Evergreen 3.0 Release Notes
===========================
:toc:
:numbered:

Upgrade notes
-------------

The minimum version of PostgreSQL required to run Evergreen 3.0 is PostgreSQL 9.4.

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.


New Features
------------



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.  It 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 features, 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 Admin > 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
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Admin -> Server Admin -> '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.

Upgrade notes
+++++++++++++
Administrators of Evergreen who use RTL locales and who have customized
`style-rtl.css.tt2` should now incorporate their customizations into
`style.css.tt2`.




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 correct 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 to 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.

Upgrade Notes
+++++++++++++

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

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 now
   a bit more patron-friendly, and can now be tweaked via TPAC template
   customization.





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
     Server Administration->Copy Tag Types
  * `ADMIN_COPY_TAG`: required to create a new tag under
    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 settings 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 of 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 against users.

Editing users
+++++++++++++

The 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

Each change set requires a name. Buckets may have multiple change sets. All
users in the Bucket at the time of processing are updated when the change
set is processed, and change sets are processed immediately upon successful
creation. The interface delivers progress information regarding the
processing stage and percent of completion.

While processing the users, the original value for each field edited is
recorded for potential future rollback. Users can examine the success and
failure of applied change sets.

The user will be able to rollback the entire change set, but not parts thereof.
The rollback will affect only those users that were successfully updated by the
original change set and may be different from the current set of users in the
Bucket. Users can manually discard change sets, removing them from the
interface but preventing future rollback.

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.

Each delete set requires a name. Buckets may have multiple delete sets. All
users in the Bucket at the time of processing are marked as deleted when
the delete set is processed. The interface delivers progress information
regarding the processing stage and percent of completion.

While processing the users, the original value for the "deleted" field will be
recorded for potential future rollback. Users are able to examine the
success and failure of applied delete sets in the same interface used for the
above described change sets.

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. No named change
sets are required. The interface will deliver progress information regarding
the processing stage and percent of completion.

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, 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.

Upgrade note
++++++++++++

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.

Details
+++++++

This is a followup to the work done in bug 1485374, 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'
YAOUS, loaded from the server when required. Additionally, closings are
recorded in the library's timezone so that 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 work in 1485374.

The OPAC is adjusted to always display the due date in the circulating
library's timezone. Because the OPAC 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.

This work, as with 1485374, was funded by SITKA, and we thank them for their
partnership in making this happen!





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 based 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

Add Circ Modifier to Record Detail Page in Staff TPAC
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The circ_modifier field is added to the table of copies to make
more information available to staff without having to open
the Holdings Maintenance 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, DOB)
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:

  * mkdir -p /openils/var/web/audio/notifications/success/patron/
  * cd /openils/var/web/audio/notifications/success/patron/
  * ln -s ../../nosound.wav by_search.wav





OPAC

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 OPAC summary display.




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 OPAC
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 TPAC
^^^^^^^^^^^^^^^^^^^
This release adds optional support for jQuery in the TPAC.  This support
is enabled by setting the ctx.want_jquery variable to a true value in the
config.tt2 TPAC 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 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.

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.
