Evergreen 3.0.6
---------------
This release is a security release that fixes cross-site scripting
(XSS) vulnerabilities in the Evergreen public catalog. This release
also includes several other bugfixes improving on Evergreen 3.0.5.

Security Issue: XSS Vulnerability in Public Catalog
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This release fixes several cross-site scripting (XSS) vulnerabilities
in the public catalog. When upgrading, Evergreen administrators should
review whether any of the following templates have been customized
or overridden. If so, either the template should be replaced with the
stock version or the XSS fix (which entails adding the `| html` filter
in several places) applied to the customized version.

* `Open-ILS/src/templates/opac/parts/record/contents.tt2`
* `Open-ILS/src/templates/opac/parts/record/copy_counts.tt2`
* `Open-ILS/src/templates/opac/parts/record/issues-mfhd.tt2`

Note that exploiting the XSS vulnerabilities fixed in this release
would require either the ability to create maliciously-constructed
MARC bibliographic or holdings records or the ability to set a
maliciously constructed organizational unit name.

Other Bugfixes
~~~~~~~~~~~~~~
Evergreen 3.0.6 also includes the following changes:

* When using 'Selection Lists -> Edit MARC Order Record' in the web
  staff client, now only one click is required to save the MARC
  record rather than two.
* The volume/copy editor in the web staff client now better handles
  editing multiple items that have different sets of statistical
  category values assigned to them.
* The act of merging bibliographic records now updates bookbags
  that referred to the source bibliographic record rather than
  effectively deleting entries for that record.
* Additional columns were added to the Holds Pull List in the
  web staff client.
* The patron registration form in the web staff client now correctly
  manages setting user preferences.
* An error in a pgTAP unit test was corrected.

* The "Replace Barcode" function now makes it more difficult for staff
members to attempt to create blank patron barcodes.
* The patron bills screen now prevents staff members from double-clicking
on the Apply Payment button (which otherwise would apply two payments).

Evergreen 3.0.3
----------------
Upgrade Notes
~~~~~~~~~~~~~
* The upgrade script for 3.0.3 contains a post-transaction command to forcibly
update the visibility attributes of all bibs that make use of Located URIs or
bib sources. It may take a while to run on large datasets.  If it it running
too long, it can be canceled and the following psql commands will create and
run a script that will perform the same action serially over time without
blocking writes to bibs:
----
\t
\o /tmp/luri_visibility_update.sql
SELECT 'UPDATE biblio.record_entry SET ' ||
  'vis_attr_vector = biblio.calculate_bib_visibility_attribute_set(id) ' ||
  'WHERE id = ' || id || '; SELECT ' || id || ';'
FROM biblio.record_entry
  WHERE id IN (
            SELECT  DISTINCT cn.record
              FROM  asset.call_number cn
              WHERE NOT cn.deleted
                    AND cn.label = '##URI##'
                    AND EXISTS (
                        SELECT  1
                          FROM  asset.uri_call_number_map m
                          WHERE m.call_number = cn.id
                    )
                UNION
            SELECT id FROM biblio.record_entry WHERE source IS NOT NULL

        );
\o
\t
\i /tmp/luri_visibility_update.sql
----

It will output the id of each updated bib so that the script can be killed
and then edited to remove completed bibs.  The remainder can be run at a
later time.

NOTE: When the internal flag 'ingest.reingest.force_on_same_marc' is enabled,
we do NOT update the bib's visibility attributes, as doing so causes a loop
and an eventual trigger stack violation.  This flag should ONLY be used when
forcing reingest of record attributes (NOT visibility attributes), search,
facet, and display fields, so if using this flag under normal operation,
proceed at your own risk and know that Located URI and bib source changes
will not be reflected in the visibility attributes of the record.

Bug Fixes
~~~~~~~~~
This release contains several bug fixes improving on Evergreen 3.0.1:

* Fixes several issues related to the display of located URIs and records with
bib sources in search results.
* Setting `opac_visible` to false for a copy location group now hides only
the location group itself, rather than also hiding every single copy in the
group.
* Fixes a bug that prevented the copy editor from displaying the _fine level_
and _loan duration_ fields.
* The "Edit Items" grid action in the Item Status interface will now open
in the combined volume/copy editor in batch.  This makes the behavior
consistent with the "Edit Selected Items" grid action in the copy
buckets interface.
* Staff members are now required to choose a billing type when creating a
bill on a user account.
* The Web client now provides staff users with an alert and option to
override when an item with the Lost and Paid status is checked in.
* Fixes a bug where the Web client offline circ interface was not able
to set its working location.
* Fixes an issue that prevented the ADMIN_COPY_TAG permission from being
granted.
* The MARC editor in the Web staff client now presents bib sources in
alphabetical order.
* Both circulation and grocery bills are now printed when a staff user selects
a patron account and clicks "Print Bills".
* Fixes an issue in the XUL serials interface the "Receive move/selected"
action from succeeding.
* Fixes a typo in the user password testing interface.

Evergreen 3.0.2
----------------
This release contains several bug fixes improving on Evergreen 3.0.1:

* Copy templates created in XUL Holdings Maintenance will now be
automatically converted and displayed in the web staff client's
volume/copy editor.
* The list of report templates now includes a column indicating whether
the template was originally created in the XUL staff client or the web
staff client; staff need to know this since report templates created in
one interface cannot be edited in the other.

in the web staff client, including
** Pending Copy Buckets
** Copy Buckets
** Checkin/Capture Holds
** Holds Shelf
** Patron Bills History
** Patron Checkout
** Patron Holds
** Patron Items Out
** Copy Editor
** In-House Uses
** Renew Items
** Bib Record View Holds
** Transit List
* Many patron fields have been redacted from the web staff client's patron
and record holds grids, leaving patron name, username, and ID.
* Fixes two bugs where patron records could fail to be saved upon editing.
* The web staff patron editor now better warns staff users about
duplicate names, IDs, phone numbers, and email addresses.
* Human readable labels are now displayed for certain fields in standing
penalty records.

primary and secondary ID values.
* The web staff client's billing full details page now displays
information about the staff user that created a payment.
* The web staff client now requires staff users to explicitly set a
billing type when adding a manual bill.
* The web staff client's patron bill annotation modal now works.
* Patron barcode search completion in the web staff client now allows
the user to select from all of the matching patron records.
* The Hold Shelf Slip print template in the web staff client now has
access to the call number.

now include copy barcode and title.
* Fixes a bug that resulted in some catalog searches unexpectedly
timing out.
* Fixes a bug that resulted in catalog searches that specify a location
limit returning incorrect results.
* Fixes a bug where deleted copies could make records visible in the
public catalog.
* Fixes a bug where certain queries on copies used in the public catalog
could be very slow.
* Fixes a bug place a hold request in the public catalog could result
in "forgetting" the type and library of the user's previous search.
* The web staff client now respects staff user session timeouts, and
will log out all open tabs if a user's session has timed out.
* The web staff Z39.50 page will now give the staff user an alert if
they attempt to import a record with a duplicate TCN.
* Fixes a bug that prevented copy notes, copy tags, and copy bucket
entries from being deleted.
* Fixes a bug that made using the volume/copy editor to change a copy's
price problematic.
* The administration interface for hard due dates now ensures that
new (or edited) ceiling dates have their time component set to end
of day, resolving an issue where ceiling dates would not be applied
during the ceiling date itself.
* The web staff client can now include dynamic information in browser
tab titles, e.g., "Smith, Jane - Checkout".
* The Concerto sample data set now includes data allowing for testing
placing holds on monographic parts.
* Asset merging during bibliographic record merging now correctly
recognizes call number prefixes and suffixes and deletes disused
call number records.
* Fixes a bug where displaying user surveys could result in PCRUD
drone starvation.
* Fixes a bug where pg_restore of an Evergreen database could fail
to create certain indexes on the `actor.usr` table.

from saving column configuration changes in the web staff client.
* Fixes a bug in the web staff client where a billing prompt did not
correctly display after marking an item damaged in those systems that

3.0.0 Upgrade notes
-------------------

The minimum version of PostgreSQL required to run Evergreen 3.0 is
PostgreSQL 9.4. Evergreen 3.0 also requires OpenSRF 3.0.0 or later.

Change to Names of Shared Libraries
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
OpenSRF 3.0 changes how the shared libraries for services written in
C are named.  If upgrading from an earlier version of Evergreen,
`opensrf.xml` should be edited so that shared library file names
listed in the `<implementation>` tag start with "lib".  For example,

[source,sh]
---------------------------------------------------------------------
            <open-ils.cstore>
                <language>C</language>
                <implementation>oils_cstore.so</implementation>
---------------------------------------------------------------------

should be changed to:

[source,sh]
---------------------------------------------------------------------
            <open-ils.cstore>
                <language>C</language>
                <implementation>liboils_cstore.so</implementation>
---------------------------------------------------------------------

SIP Bugfix Requires SIPServer Upgrade
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The fix for Launchpad Bug 1542495: "OpenILS::SIP::clean_text() can
crash" requires that you also upgrade SIPServer with the fix for
Launchpad Bug 1463943: "Non-ascii Unicode characters in messages cause
SIP client problems."  This means that if you use SIP2 with Evergreen,
you must also upgrade SIPServer to the latest commit in the Git
repository.  Conversely, if you upgrade SIPServer to the latest commit
in Git, you must also upgrade Evergreen or, at least, apply the patch
for Launchpad Bug 1542495.  These two patches are complementary and
cannot be applied independently of one another.

`open-ils.auth.login`
~~~~~~~~~~~~~~~~~~~~~
The new `open-ils.auth.login` API must be added to the list of `<log_protect>`
API's in the `opensrf_core.xml` file.

Sample diff:

RTL CSS Stylesheet
~~~~~~~~~~~~~~~~~~
Administrators of Evergreen who use RTL locales and who have customized
`style-rtl.css.tt2` should now incorporate their customizations into
`style.css.tt2`.

Multi-Time Zone Installations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Evergreen consortia that span more than one time zone, the following
query will adjust all historical, unaged circulations so
that if their due date field is pushed to the end of the day, it is done
in the circulating library's time zone, and not the server time zone.

It is safe to run this after any change to library time zones.

Running this is not required, as no code before this change has
depended on the time string of '23:59:59'.  It is also not necessary
if all of your libraries are in the same time zone, and that time zone
is the same as the database's configured time zone.

[source,sql]

            end if;
        end loop;
    end loop;
end;
$$;
----


Deprecation of XUL staff client
-------------------------------
Starting with the release of 3.0.0, patches that fix XUL bugs will not
be merged into master or backported unless they meet one or more of
the following conditions:

a. the bug is a security issue
b. the bug involves the destruction of data
c. the bug is a regression of functionality in the XUL staff client
   introduced by other work done to Evergreen

Under no circumstances will XUL staff client feature enhancements be merged.

This policy will continue through the 3.0.x and 3.1.x maintenance
release cycles, and will become moot upon the release of 3.2.0, when
the XUL staff client is slated to be entirely removed.


3.0.0 New Features
------------------

New Staff Client
~~~~~~~~~~~~~~~~

Evergreen 3.0 features a new, modern staff client that runs in the web browser
and can be used on desktop and mobile devices. All functional areas of the 
system, including circulation, cataloging, acquisitions, serials, reports,
booking, administration, and offline circulation, are available in the new staff 
client. Chrome and Firefox are officially supported for use with the web client.

Library staff will no longer need to download separate software to perform most 
actions in Evergreen. A Chrome plugin called Hatch will be available as a 
separate installation for workstations that require seamless, dialog-free
printing to multiple printers.  

In addition to adding more portability and stability, the new staff client also
presents a cleaner and more modern interface for users. By virtue of running in
a browser, actions that users are accustomed to performing on other web sites
should now be available in the Evergreen client.

The old, XUL client will continue to be available to allow for a gradual 
transition to the browser-based client, but no new features will be added. The
old client will totally be removed from Evergreen in the Fall 2018 3.2.0
release.



Administration
~~~~~~~~~~~~~~



New EDI Order Generator 
^^^^^^^^^^^^^^^^^^^^^^^

Configuration
+++++++++++++

. New database tables exist for configuring vendor-specific EDI order 
attributes.

 * `acq.edi_attr .
  ** List of EDI order generation toggles, e.g. "INCLUDE_COPIES" to add 
     GIR segments
 * `acq.edi_attr_set`
  ** Collection of `edi_attr`s.  Each edi_account may be linked to one
     `edi_attr_set`.
  ** One `edi_attr_set` per known vendor is added to the stock data, matching
     the stock configuration found in the JEDI template.
 * `acq.edi_attr_set_map`
  ** Link between `edi_attr`s and `edi_attr_set`s.

. EDI Attribute Sets are manged via a new (browser client only) configuration
  interface at 'Administration -> Acquisitions Administration -> EDI
  Attribute Sets'.

. Each `acq.edi_account` should be linked to an `acq.edi_attr_set`.  If a link
  is not set, default values will be used.  Links between an EDI account
  and an attribute set are managed in the EDI Accounts configuration 
  interface.

. Local modifications to the stock EG JEDI template are managed by modifying
  and/or adding additional `edi_att_set`s as needed.

. A new `edi_order_pusher.pl` script is added which replaces the functionality
  of `edi_pusher.pl`.  `edi_pusher.pl` is still available.

. After moving to `edi_order_pusher.pl`, the JEDI Action/Trigger event
  definition is no longer required and can be disabled.

Migration
+++++++++

EDI accounts have a new boolean field 'Use EDI Attributes' (`use_attrs`) that
specifies whether PO's generated via the account should be built using 
EDI attributes or fall back to traditional JEDI A/T template generation.

This allows sites to activate EDI attributes on a per-account basis, making 
it possible to migrate piecemeal to EDI attributes.  For the initial roll
out of this new feature, no accounts will be configured to use EDI 
attributes by default.  





3 Day Courtesy Notice by SMS
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
New optional SMS text notification to be sent out 3 days prior to the due
date of any circulating item for patrons who have an SMS text number and
carrier stored in their accounts. This action trigger is disabled by default,
but can be enabled and modified by going into 'Administration -> Local Administration ->
Notifications / Action Triggers'.

You may wish to make use of granularity so that these messages are batched
and sent at the same time each day.




Add Description Field to Circulation and Hold Configuration Entries
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The circulation and hold policy configuration rules now each have a
description field. This allows administrators to add comments to
describe the purpose of each rule.




Apache Internal Port Configuration Option
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Apache configuration now supports a new variable which allows admins to
specify the port used by Apache to handle HTTP traffic.  The value is
used for HTTP requests routed from Perl handlers back to the same Apache
instance, like added content requests.  Use this when running Apache
with a non-standard port, typical with a proxy setup.  Defaults to "80".

[source,conf]
-------------------------------------------------------------------
<Location /eg>
    ...
    PerlSetVar OILSWebInternalHTTPPort "7080"
    ...
</Location>
-------------------------------------------------------------------




Configurable Bib Record Display Fields
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

'Administration -> Server Administration -> MARC Search/Facet Fields' have 2 new configuration 
fields: 'Display Field?' and 'Display XPath'.

When 'Display Field' is set to true, data from the field will be extracted
from each record and added to a new table of display data for each bib 
record.  

If a value is present in the 'Display XPath' field, this XPath will be
applied to the extracted data *after* the base XPath (from the 'XPath' 
field) is applied to each field.

This data acts as a replacement for the various and sundry ways bib record 
data is currently extracted, including inline XPath in the TPAC, reporter 
views, real-time 'MVR' compilation from MODS, etc. and will be available
to the user interface, notification templates, etc. for rendering bib 
records.  

The browser client gets a new service 'egBibDisplay' which is capable
of translating the display field data from various formats into 
data more suitable for JavaScript usage.

The database gets 3 new views for representing display data in various
formats:

 * `metabib.flat_display_entry`
  ** List of all display fields linked to their configuration.
 * `metabib.compressed_display_entry`
  ** Same as `metabib.flat_display_entry` except there's one row
     per display field type, with 'multi' rows compressed into
     JSON arrays.  Non-multi fields are represented as JSON 
     strings/numbers.
 * `metabib.wide_display_entry`
  ** Tabular view of display field data, one column per well-known
     field.  Values are represented JSON, consistent with 
     `metabib.flat_display_entry`.  The view does *not* contain locally
     configured display fields, as each field must be encoded in
     the view and IDL definition.  This is essentially a replacement 
     for `reporter.simple_record`.

Reingesting
+++++++++++

After making changes to display field configuration, it's possible to 
reingest only display field data in the database using the following:

[source,sql]
---------------------------------------------------------------------
SELECT metabib.reingest_metabib_field_entries(id, TRUE, FALSE, TRUE, TRUE, 
  (SELECT ARRAY_AGG(id)::INT[] FROM config.metabib_field WHERE display_field))
  FROM biblio.record_entry WHERE NOT deleted AND id > 0;
---------------------------------------------------------------------





Fix COPY_STATUS_LONGOVERDUE.override Permission Typo
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The existing permission was incorrectly created with a code of
`COPY_STATUS_LONGOVERDUE.override`, while the event thrown requires a
permission with a code of `COPY_STATUS_LONG_OVERDUE.override`.  This
update changes the permission code to match what the event requires.





Hold Targeter V2 Repairs and Improvements
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Make the batch targeter more resilient to a single-hold failure.
* Additional batch targeter info logging.
* Set `OSRF_LOG_CLIENT` in `hold_targeter_v2.pl` for log tracing
* Removes the confusingly named `--target-all` option
 ** The same behavior can be achieved by using `--retarget-interval "0s"`
* Removes `--skip-viable` (see `--soft-retarget-interval` below)

New --next-check-interval Option
++++++++++++++++++++++++++++++++
Specify how long after the current run time the targeter will retarget
the currently affected holds. Applying a specific interval is useful
when the retarget-interval is shorter than the time between targeter
runs.

For example, if the targeter is run nightly at midnight with a
`--retarget-interval 36h`, you would set `--next-check-interval` to `48hr`,
since the holds won't be processed again until 48 hours later. This
ensures that the org unit closed date checks are looking at the correct
date. 

This setting overrides the default behavior of calculating the next 
retarget time from the retarget-interval.

New --soft-retarget-interval Option
+++++++++++++++++++++++++++++++++++
This is a replacement for (and rebranding of) the `--skip-viable` option. 
The new option allows for time-based soft-targeting instead simple binary 
on/off soft-targeting.

How soft-targeting works:

* Update hold copy maps for all affected holds
* Holds with viable targets (on the pull list) are otherwise left alone.
* Holds without viable targets are retargeted in the usual manner. 





New marc_export --descendants Option
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The `marc_export` script has a new option, `--descendants`.  This option
takes one argument of an organizational unit shortname.  It works much
like the existing `--library` option except that it is aware of the
org. tree and will export records with holdings at the specified
organizational unit and all of its descendants.  This is handy if you
want to export the records for all of the branches of a system.  You
can do that by specifying this option and the system's shortname,
instead of specifying multiple `--library` options for each branch.

The `--descendants` option can be repeated, as the `--library` option can.
All of the specified org. units and their descendants will be included
in the output.  It can also be combined with individual `--library`
options when necessary.




RTL and LTR Public Catalog Stylesheets Merged
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The RTL stylesheet for the public catalog,
`templates/opac/css/style-rtl.css.tt2`, has been merged into the LTR
one (`templates/opac/css/style.css.tt2`). The combined stylesheet
template will provide RTL or LTR styles based on the value of
the `rtl` flag of the active locale. An `rtl` variable is also available
in the template to allow the correct style to be chosen.




Miscellaneous Improvements
^^^^^^^^^^^^^^^^^^^^^^^^^^

 * If a filter is in effect in the Library Settings Editor,
   the filter will continue to be applied after a user 
   changes the selected library.
 * Copy templates used for serials now correctly link to age
   protection rules and MARC item type values (for the
   "Circ as Type" field). During upgrade, the database update
   will set to NULL any age protection and circ as type fields
   in serial copy templates that do not point to defined values.




Obsolete Internal Flag Removed
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

An obsolete and unused `ingest.disable_metabib_field_entry` internal
flag was removed from the `config.internal_flags` table.  It was
rendered obsolete by the addition of the 3 flags to control the
browse, search, and facet indexing.




Tweaks to Caching/Expiry of Public Catalog Assets
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The default cache expiration time for static assets (e.g.,
CSS, image, and JavaScript files) in the public catalog and
the Kid's PAC has been increased to one year. Links to all
such assets now have a cache-busting value tacked on as a
query parameter. This value is refreshed when `autogen.sh` is
run, but it can also be manually set by adjusting the
`ctx.cache_key` Template Toolkit variable.




Action/Trigger Events Data Purging
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Action/Trigger event definitions have a new field called 'Retention 
Interval'.  When an optional interval value is applied, events and
template output data linked to the event definition will be deleted
from the database once they reach the specified age.

Retention Interval Restrictions for Passive Hooks
+++++++++++++++++++++++++++++++++++++++++++++++++

Restrictions are placed on retention interval values for event definitions
using passive hooks to prevent data from being deleted while it's still
needed by the system.

The presence of event data is how the system knows not to send duplicate
events.  As long as a scenario exists where a duplicate event may be
generated, the events must be retained.

To apply a retention interval value to a passive-hook event definition:

 * The event definition must have a max_delay value.
 * The retention interval must be larger than the difference between
   the `delay` and `max_delay` values.

For example, if the `delay` is 7 days and `max_delay` is 10 days, the retention
interval must be greater than 3 days to ensure no duplicate events are 
created between the first event on day 7 and the end of the event validity
window on day 10.

Deployment
++++++++++

A new `purge_at_events.sh` script is installed in the bin directory
(typically `/openils/bin`) which should be added to CRON for regular
maintenance.

NOTE: On large data sets, this script can take a long time to run and
create higher than normal I/O load as it churns though the event and
event_output tables.  You may wish to run the script by hand the first
time so it can be monitored.  It can be run in psql like so:

[source,sql]
---------------------------------------------------------------
SELECT action_trigger.purge_events();
---------------------------------------------------------------

NOTE: On *very* large data sets (10s to 100s of millions of event and
event_output rows), it may be advisable to first repopulate the `event`
and `event_output` tables with only the desired data before starting
regular purges.  This can be done, for example, using the copy to temp
table, truncate source table, repopulate source table from temp table
approach.  This will be much faster than the `purge_events()` function
in cases where most of the data will be purged.

Hook Data Cleanup
+++++++++++++++++

A number of `action_trigger.hook` entries which have always been treated
as active hooks, though are configured as passive hooks, have been 
updated to properly reflect the non-passive-ness.  This allows for 
simpler configuration of their retention interval values.





Remove JSPAC Redirects
^^^^^^^^^^^^^^^^^^^^^^
Future versions of Evergreen will no longer contain automatic redirects
from JSPAC URLs to TPAC URLs, with the exception of `myopac.xml`, given
that the JSPAC is no longer supported.  Existing sites, however, may
wish to retain JSPAC redirects in their Apache configuration files since
JSPAC URLs may still be used in the wild to access their catalogs.

The original JSPAC URL redirects are all retained in the file 
`Open-ILS/examples/jspac_redirects.conf` for reference.




API
~~~



New open-ils.auth.login API
^^^^^^^^^^^^^^^^^^^^^^^^^^^
The `open-ils.auth` service has a new API for requesting an authentication
token.  It performs the same steps as the 
`open-ils.auth.authenticate.init` and `.complete` APIs in a single call,
using the bare password.  No intermediate password hashing is required.

The paramaters are the same as the `.complete` call with a few modifications.

1. Using the generic 'identifier' parameter in combination with the
   'org' parameter allows the API to reliably determine if an identifier
   value is a username or barcode.  The caller is no longer required to 
   make that determination up front.  

2. The 'nonce' parameter is no longer used.





Batch Patron Contact Invalidation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following methods are used to mark patron contact fields
as invalid by moving the invalid value to a standing penalty:

 * `open-ils.actor.invalidate.email`
 * `open-ils.actor.invalidate.day_phone`
 * `open-ils.actor.invalidate.evening_phone`
 * `open-ils.actor.invalidate.other_phone`

These methods now accept a fifth argument specifying the value
of the contact field, e.g., a specific phone number or email
address. If supplied, and if a specific patron ID (the first
argument) is not supplied, all patrons with that specific contact
value will have it marked invalid.




Architecture
~~~~~~~~~~~~



Pure-SQL catalog searching
^^^^^^^^^^^^^^^^^^^^^^^^^^
Public and staff catalog search is now both more accurate and faster
by redesigning how the visibility of records is calculated.




Cataloging
~~~~~~~~~~



Authority Record and Headings Browse Improvements
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Various improvements are made to support for authority records
and headings browsing:

 * The MARC to MADS XSLT stylesheet is now used as part of parsing
   headings from authority records. Since the MODS and MADS stylesheets
   extract headings in similar ways, duplicate browse entries are now
   much less likely to occur.
 * A new configuration table, `authority.heading_field`, is now used
   to specify how headings should be extracted from authority records.
 * Related headings can now be identified as narrower or broader when
   browsing in the public catalog.
 * See references are now more reliably included in the browse list.
 * Scope (public) notes now display only under the main heading.
 * There is now a global flag, Display related headings (see-also) in browse,
   that can be used to control whether related headings (see-alsos) are
   displayed in the public catalog list.
 * A complete set of thesauruses are now included in the seed data.  Thesauruses
   can now be identified using short and long codes.
 * The labels for see and see-also references in the public catalog are 
   a bit more patron-friendly, and can now be tweaked via TPAC template
   customization in the browse.tt2 file.





Copy Tags and Digital Bookplates
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Copy tags will allow staff to apply custom, pre-defined labels or tags
to copies.  Copy tags are searchable in both the staff client and public
catalog.  This feature was designed to be used for Digital Bookplates to
attach donation or memorial information to copies, but may be used for
broader purposes to tag items.

Each copy tag can either be publicly-visible or visible only to staff.
Copy tags also have types that can be used for restricting catalog
searches on copy tags to particular types.

Copy tags are displayed in the copy table in the record summary page in
the public catalog, and a new library setting can be used to add
a "Digital Bookplate" search field.  Copy tags can also be used
as a search filter, e.g.,

  * `copy_tag(bookplate, jane smith)`: search for records that have a
    copy tag of type 'bookplate' whose value contains 'jane smith'.
  * `copy_tag(*, jane smith)`: search for records that have a
    copy tag of any type whose value contains 'jane smith'.

All staff-side interfaces related to copy tags exist only in the web
staff client.  There are two new administration interfaces for managing
copy tags and copy tag types. The copy editor now has a 'Copy Tags'
button for applying copy tags to copies; that interface can also be
used to create new copy tags on the fly. Furthermore, the copy buckets
interface now has an 'Apply Tags' action for assigning tags to groups
of copies.

Permissions
+++++++++++

Two new permission are included:

  * `ADMIN_COPY_TAG_TYPES`: required to create a new tag type under
     'Administration -> Server Administration -> Copy Tag Types'
  * `ADMIN_COPY_TAG`: required to create a new tag under
    'Administration -> Local Administration -> Copy Tags'

The existing permission `UPDATE_COPY` controls whether or not a user
can link copies to tags.

Library Settings
++++++++++++++++
A new library setting, 'Enable Digital Bookplate Search', controls
whether to display a 'Digital Bookplate' field in the search index
drop-downs in the catalog. A 'Digital Bookplate' search will include
all records that have a copy that matches the tag specified by the user.
It should be noted that this library setting does not affect the
display of copy tags on the catalog record summary page.




Include Call Number Prefixes and Suffixes in Export and Z39.50 output
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The call number prefix and suffix, when present, are now included in
subfields $k and $m of the 852 field when running `marc_export` with
the `--items` switch. Similarly, when using Evergreen as a Z39.50
server configured to embed item data in 852 fields, the affixes are now
included in subfields $k and $m.




Circulation
~~~~~~~~~~~



Batch Editing of Patron Records
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
There is a now a new interface analogous to the Copy Bucket interface
to select and group a set of users into a User Bucket.
The addition of users to a User Bucket is possible from the Patron Search
interface by the use of a new grid Action, and directly on the User Bucket
interface by user barcode. It is also possible to add users to a User
Bucket by uploading a text file that contains a list of user barcodes.

From this interface it is possible to perform a set of specific batch update
operations on user records.

Editing Users
+++++++++++++

These fields can now be changed in batch via an action on the User Bucket
grid if the staff user has the `UPDATE_USER` permission:

 * Active flag
 * Primary Permission Group (group application permissions consulted)
 * Juvenile flag
 * Home Library (`UPDATE_USER` checked against both old and new value)
 * Privilege Expiration Date
 * Barred flag (`BAR_PATRON` permission consulted)
 * Internet Access Level

Changes made in this interface can be rolled back.

As a batch process, rather than a direct edit, this mechanism explicitly skips
processing of Action/Trigger event definitions for user update.

Deleting Users
++++++++++++++

The batch edit mechanism also allows for the batch deletion of user.  The staff
user must have both the `UPDATE_USER` and `DELETE_USER` permissions.

Changes made in this interface can be rolled back.

As a batch process, rather than a direct edit, this mechanism explicitly skips
processing of Action/Trigger event definitions for user deletion.

This mechanism does not use the Purge User functionality, but instead simply
marks the users as deleted.

Editing Statistical Category Entries
++++++++++++++++++++++++++++++++++++

All users in the bucket can have their Statistical Category Entries
modified. Unlike user data field updates, modification of Statistical
Category Entries is permanent and cannot be rolled back.

As a batch process, rather than a direct edit, this mechanism explicitly skips
processing of Action/Trigger event definitions for user update.

New Service Requirement
+++++++++++++++++++++++

This new functionality makes use of the QStore service (`open-ils.qstore`), which was previously
unused in production.  If this service has been removed from the configuration
of a live Evergreen instances, it will need to be added back in order for
batch user editing to succeed.




Honor Timezone of the Acting Library
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Summary
+++++++

* Display day-granular due dates in the circulating library's timezone.
* Only display the date portion of the due date for day-granular circulations.
* Display the full timestamp, in the client's timezone rather than the circulation library's, for hourly circulations.
* Provide infrastructure for more advanced formatting of timestamps.
* Override the built-in AngularJS date filter with an implementation that uses moment.js, providing consistency and better standards compliance.

Details
+++++++

This is a followup to the work done for 2.12, where we added the ability
for the client to specify a timezone in which timestamps should be interpreted
in business logic and the database.

Most specifically, this work focuses on circulation due dates and the closed
date editor. Due dates, where displayed using stock templates (including
receipt templates) and used for fine calculation, are now manipulated in the
library's configured timezone. This is controlled by the new 'lib.timezone'
setting available via the Library Settings Editor, loaded from the server when
required. Additionally, closings are recorded in the library's timezone so that
due date calculation is more accurate. The closed date editor is also
taught how to display closings in the
closed library's timezone. Closed date entries also explicitly record if they
are a full day closing, or a multi-day closing. This significantly simplifies
the editor, and may be useful in other contexts.

To accomplish this, we use the moment.js library and the moment-timezone addon.
This is necessary because the stock AngularJS date filter does not understand
locale-aware timezone values, which are required to support DST. A simple
mapper translates the differences in format values from AngularJS date to
moment.js.

Of special note are a set of new filters used for formatting timestamps under
certain circumstances. The new egOrgDateInContext, egOrgDate, and egDueDate
filters provide the functionality, and autogrid is enhanced to make use of
these where applicable. egGrid and egGridField are also taught to accept
default and field-specific options for applying date filters. These filters may
be useful in other or related contexts.

The egDueDate filter, used for all existing displays of due date via Angular
code, intentionally interprets timestamps in two different ways WRT timezone,
based on the circulation duration. If the duration is day-granular (that is,
the number of seconds in the duration is divisible by 86,400, or 24 hours worth
of seconds) then the date is interpreted as being in the circulation library's
timezone. If it is an hourly loan (any duration that does not meet the
day-granular criterium) then it is instead displayed in the client's timezone,
just as all other timestamps currently are, because of the previous Evergreen
timezone work.

The public catalog is adjusted to always display the due date in the circulating
library's timezone. Because the public catalog displays only the date portion of the due
date field, this difference is currently considered acceptable. If this proves
to be a problem in the future, a minor adjustment can be made to match the
egDueDate filter logic.

Now that due dates are globally stored in the configured timezone of the
circulating library, the automatic adjustment to day-granular due dates needs
to take those timezones into account.

An optional SQL command is provided by the upgrade script to retroactively
adjust existing due dates after library configuration is complete.





Enhancements to Hard Due Date Functionality
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It will now be possible to delete Hard Due Date Values for dates that have
passed. Also, the Hard Due Date updater will no longer change Ceiling Dates
to a past date. This allows editing Ceiling Dates directly in a Hard Due Date
as well as scheduling Ceiling Date changes via Hard Due Date Values.




Patron Search by Birth Date
^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Now you can include the patron birth year and/or birth month and/or
  birth day when searching for patrons using the web staff client.
* Day and month values are exact matches.  E.g. month "1" (or "01")
  matches January, "12" matches December.
* Year searches are "contains" searches.  E.g. year "15" matches 2015,
  1915, 1599, etc.  For exact matches use the full 4-digit year.



Patron Search from Place Hold
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This feature allows staff members, when placing a
hold on behalf of a patron in the web staff client, to search for
patrons by names and other searchable patron information, rather than
relying on barcode alone. In particular, after performing a catalog
search or going to a specific bib record and clicking the 'Place Hold'
button, the form now includes a 'Patron Search' button. This button
will open a dialog allowing the staff member search for and select
a patron record.




Retrieve Recent Patrons 
^^^^^^^^^^^^^^^^^^^^^^^

Adds a new library setting 'Number of Retrievable Recent Patrons' 
('ui.staff.max_recent_patrons') that specifies the number of recently
retrieved patrons that can be re-fetched from the staff client.

A value of 0 means no recent patrons can be retrieved.
A value greater than 1 means staff will be able to retrieve multiple
recent patrons via a new Circulation 'Retrieve Recent Patrons' menu entry.

The default value is 1 for backwards compatibility.






Fuller title in XUL client Simplified Pull List
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The Simplified Pull List in the XUL client will now display subfields 245$n and
$p in the title field. The addition will make it easier for staff to distinguish
between different parts or seasons in a series.





Transit Cancel Time and Terminology Change
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Transit Cancel Time
+++++++++++++++++++

Previously, Evergreen deleted canceled (aborted) transits from the database.  Now
the rows in `action.transit_copy`, `action.hold_transit_copy`, and `action.reservation_transit_copy`
are preserved in the database, though still not visible to the end user in the staff client.
This allows for better tracking of when transits are canceled for the purposes of knowing
which staff member canceled the transit, etc.

NOTE: This change may require the re-creation of transit reports to filter out canceled
transits from the results.  Cloning the template and adding a 'Base Filter' of 'Cancel Time 
Is NULL' will suffice.

"Canceled Transit" Terminology Change
+++++++++++++++++++++++++++++++++++++

The term "abort" has been replaced with "cancel" in all of the affected user interfaces.
For internal continuity, however, the following permission codes have not changed:

 * `ABORT_TRANSIT`
 * `ABORT_REMOTE_TRANSIT`
 * `ABORT_TRANSIT_ON_LOST`
 * `ABORT_TRANSIT_ON_MISSING`




Client
~~~~~~

Offline Circulation Available in Web Staff Client
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Offline circulation is now available in the web staff client. In order to use the
offline interface, users must first log into the web staff client, perform
a patron search, select a user from the results, and open the patron editor
interface to collect all the relevent configuration information for the 
workstation. In addition, the offline interface available from the Circulation
menu provides a 'Download block list' button for users who are logged in.

As is the case in the old staff client, users can check materials in and out,
renew items, and create new patron accounts while offline. The patron fields
available in the offline patron registration editor are the same ones that
are available to staff when working online.



Add Circ Modifier to Record Detail Page in Staff TPAC
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The circulation modifier field is added to the table of copies to make
more information available to staff without having to open
the Holdings View.





Date+Time Format Settings for Web Client
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This change deprecates the existing 'Format Dates' and 'Format Times' settings
and adds two settings for use with the webstaff client:

  * 'Format Dates with this pattern'
  * 'Format Date+Time with this pattern'

These settings use format strings as documented here:

https://docs.angularjs.org/api/ng/filter/date

There is overlap with how the Dojo formats worked, but also some differences.

The original 'Format Dates' and 'Format Times' settings worked together, but the
new settings work independently.  Certain field elements will use one, and
certain field elements will use the other.  These distinctions are hard-coded
in the various UI templates, with the idea being that timestamp fields in
which the date component alone is sufficient information (for example, date of birth)
will use the 'Format Dates' setting.  Fields where the time component is
important (for example, checkout time) will use the 'Format Date+Time' setting.

When the settings 'Format Dates' and 'Format Date+Time' are unset, we will default
to "shortDate" (M/d/yy) and "short" (M/d/yy h:mm a), respectively.





Global Option to Remove Sound for a Specific Event
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
A new `nosound.wav` file has been added to the web client. The file can be used
to globally disable audio alerts for a specific event on an Evergreen system.

For example, to silence the alert that sounds after a successful patron search:

[source,sh]
----
mkdir -p /openils/var/web/audio/notifications/success/patron/
cd /openils/var/web/audio/notifications/success/patron/
ln -s ../../nosound.wav by_search.wav
----


Documentation
~~~~~~~~~~~~~

The official Evergreen manual has been split into eight new manuals, each
designed for a specific audience. This new approach is designed to make
the documentation more readable and usable.

The specific audiences for the new manuals are:

* Acquisitions staff
* Circulation staff
* Cataloging staff
* Public services staff who use the public catalog
* Serials staff
* System administrators who use the command line
* System administrators who use the Web client
* System administrators and programmers who wish to integrate Evergreen
with other technologies

All manuals are available at http://docs.evergreen-ils.org


Public catalog
~~~~~~~~~~~~~~

Improvements to ebook API
^^^^^^^^^^^^^^^^^^^^^^^^^

Evergreen now supports checking out and placing holds on
OverDrive and OneClickdigital ebook titles from within the public
catalog.  This is an experimental feature.  It is not recommended for production
use without careful testing.

When ebook integration is enabled, a "Check Out E-Item" link will be
displayed when viewing an ebook title from a supported vendor in the
catalog.  Clicking on the link allows the user to check out and download
that title from the vendor directly within the catalog.

If no copies are available for the title, a "Place Hold on E-Item" link
is displayed instead, and the user may place a hold on the title.  (Note
that some vendors require the user's account to have an email address
before permitting a hold.)

My Account includes the ability to view current ebook checkouts and
holds, download already-checked-out titles, and cancel holds.

For API integration to work, you need to request API access from the
vendor, and the vendor must have a way of authenticating your patrons.
Your Evergreen system also needs to be configured for ebook API
integration, following the instructions in the command line system
administration manual


This feature assumes that you are importing MARC records supplied by the
vendor into your Evergreen system, using Vandelay or some other MARC
import method.  This feature does not search the vendor's online
collections or automatically import vendor records into your system; it
merely augments records that are already in Evergreen.

Improvements to Bill Payment Pages
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The bill payment pages in the public catalog have been revamped
to

 * use the term "charges" instead of "fees"
 * include images of credit cards accepted
 * make the default print receipt template match other itemized receipts;
   note that this change is not automatically applied when upgrading.
 * display billing type
 * add button to pay only selected charges
 * reformat the credit card number input page





Clickable Copy Locations
^^^^^^^^^^^^^^^^^^^^^^^^
Adds a URL field to the copy locations editor. When a URL is entered in this field, 
the associated copy location will display as a link in the public catalog summary display.
This link can be useful for retrieving maps or other directions to the copy
location to aid users in finding material.




Download Checkout History CSV Fixed for Large Number of Circulations
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Downloading checkout history as a CSV from My Account has been fixed
for users with a large circulation history.  Previously, this would
time out for patrons with more than 100 or so circulations.

This feature no longer uses the action/trigger mechanism and the public catalog
now generates the CSV directly.  The old action/trigger code is still
present in the database and should be removed at some point in the
near future.




Google Books Preview Rewrite
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The Google Books Preview functionality in record detail pages has been
rewritten to modernize its style and optimize its performance:

* The Dojo JavaScript framework is no longer used, saving approximately
  150K of JavaScript and CSS and four network requests per page load.
* The Embedded Viewer is not loaded unless a possible preview is found,
  saving more network and memory overhead.
* The Google Books Loader is used to load the Embedded Viewer instead of the
  https://productforums.google.com/forum/#!topic/books-api/lZrq5cWKrTo;context-place=forum/books-api[deprecated
  Google Loader].
* All variables are self-contained and do not pollute the global namespace.
* Event listeners are registered to handle clicks, rather than attaching
  `href="javascript:function()"` to <a> elements.
* Book previews are displayed in a panel sized according to the viewport
  of the browser, improving its appearance on both mobile and desktop
  browsers.
* The rewritten code is now served up directly from
  `/js/ui/default/opac/ac_google_books.js` rather than as a TT2 template.




jQuery for the Public Catalog
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This release adds optional support for jQuery in the public catalog.  This support
is enabled by setting the `ctx.want_jquery` variable to a true value in the
`config.tt2` template.





New Popularity Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^
New popularity parameters for in-house use over time and for count of distinct
organizational units that own a title are now available. Evergreen sites
can use these parameters to create new statistical popularity badges for
sorting in the catalog by Most Popular or by Popularity-Adjusted Relevance.

The in-house use parameters will apply a badge to titles that have the most
in-house use activity over time. The organizational unit count parameter
will apply a badge to titles owned by the most number of libraries in a
consortium. Ownership is determined by the copy's circulation library.




Option to Suspend Holds at the Time They are Placed
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Users now have the option to suspend a hold at the same time they place the
hold. The 'Place Hold' screen has a checkbox that can be enabled for users
who want to suspend a hold at the time it is placed. There is also an option
to set the activation date at the same time. This option is also available
when placing holds on a batch of titles from 'My List' and will apply to
all the titles in the batch.





Reports
~~~~~~~



Fix to reporter.classic_current_circ View
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The `reporter.classic_current_circ` view, which is part of some
extra views defined in `Open-ILS/src/sql/Pg/example.reporter-extension.sql`,
has been fixed to not exclude loans for patrons who do not have a
billing address set. Users of this view should rerun
`Open-ILS/src/sql/Pg/example.reporter-extension.sql` during upgrade.




New Report Source Table Allowing Report of "Last" Deleted copy
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This source table allows you to construct a clever aggregate report template
which will report bibliographic IDs where a library or a group of libraries 
no longer have a copy attached but *had* a copy attached. This is especially
useful when a holdings sync is required with an external vendor.


Instructions for creating a report template with this source:

  * Create a new report template using "Library Holdings Count with Deleted" as the source
  * Add "Has Only Deleted Copies 0/1" (Min) to the Aggregate Filters -> Change Value to "1"
  * Add "Last Edit Date" (Max) to Aggregate Filters.  In Aggregate Filters, change the operator to "Between"
  * Add Circulation Library -> "Organizational Unit ID" to Base Filters, with the Raw Data transform.  In the list of Base Filters, change the operator to "In list"
  * Add "Bib ID" to Displayed Fields
  * Add "Last Edit Date" to Displayed Fields and Change Transform to Max
  * Add "Has Only Deleted Copies 0/1" to Displayed Fields and Change Transform to Min
  * Add "Total copies attached" to Displayed Fields and Change Transform to Sum


This template will only output bibliographic IDs where all of the copies for the specified branch(es)
are deleted. Furthermore, it will only output bibs whose copies were edited (deleted) during the 
specified date range. Unfortunately the user will have to manually type the date range without the date
picker. This view will also allow you to answer questions like "Show me bibs where I have one visible
copy and more than two deleted copies."




Add Provider to Provider Note Link
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The Provider reporting source now includes a link to the Provider Note reporting source.




Link ILS User and Working Location Reporting Sources
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The Working Location reporting source now has labels
and it is now linked to the ILS User reporting source, allowing
reports to display or filter on staff working location.




New Circulation Report Source "All Circulation Combined Types"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This report source will allow you to create a single report template for all of the following:

 * In-house uses
 * In-house uses of non-cataloged items
 * Circulations
 * Circulations of non-cataloged items

To distinguish between these different types of library use, it's important to display these columns
in your report templates:

 * Item Type
 * Circulation Type





Reports Template Searching
^^^^^^^^^^^^^^^^^^^^^^^^^^
A new form appears along the top of the reports interface for searching
report templates.  Once found, typical template actions (e.g. create new
report) are available from within the results interface.

Searches may be performed across selected (visible) folders or all 
folders visible to the logged in user.

Searches are case-insensitive, any word order, with left-anchored words.  
All searched words must appear in at least one of the searched fields.

Examples
++++++++

 * Searching for 'stat cat' matches:
  ** stat cat
  ** statistical category
  ** categories, statistical
  ** patrons (stat cat)
 * Searching for 'stat cat' does not match:
  ** stat 
   *** both words must be present in the searched field(s)
  ** stat location
    *** location contains 'cat' but it's not left-anchored.

Reporter Paging
+++++++++++++++

The templates, reports, and output interfaces now support paging via 
new 'Next', 'Prev', and 'Start' links next to the output limit selector.






Serials
~~~~~~~



Web Staff Client Serials Module
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The serials module has been ported over to the web staff
client, implementing a unified serials interface that combines
ideas from both the serial control view and alternate serials
control view from the old staff client.

In addition to carrying over functionality that was available
in the old staff client, several new features are included:

* the ability to save prediction pattern codes as templates
  that can be shared and reused within an Evergreen database
* a more streamlined interface for managing subscriptions,
  distributions, and streams
* it is no longer necessary to create a starting issue in
  order to predict a run of issues; the dialog box for
  generating a set of predicted issues now lets you specify
  the starting point directly.
* the ability to more directly edit MFHDs
    
The new serials interfaces can be accessed from the record
details page via a Serials drop-down button that links to
a subscription management page, a quick-receive action, and
a MFHD management page. There is also a new 'Serials Administration'
page where prediction pattern and serial copy templates can
be managed.




SIP
~~~



SIP Bugfix Changes How Encoding Is Determined in Configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The combined fix for the above mentioned SIP bugs alters the way that
SIPServer looks up the output encoding in the configuration file (typically
`oils_sip.xml`).  SIPServer now looks for the encoding in the following
places:

1. An +encoding+ attribute on the +account+ element for the currently active SIP account.
2. The +encoding+ element that is a child of the +institution+ element of the currently active SIP account.
3. The +encoding+ element that is a child of the +implementation_config+ element that is itself a child of the +institution+ element of the currently active SIP account.
4. If none of the above exist, then the default encoding (ASCII) is used.

Number 3 is provided to ease the transition to the new code.  It is
the current location of the +encoding+ element in the sample
configuration file and as such, where it is likely to be found in
actual files.  It is recommended that you alter your configuration to
move this element out of the +implementation_config+ element and into
its parent +institution+ element.  Ideally, SIPServer should *not* look into
the implementation config, and this check may be removed at some time
in the future.
