[28679] Unable to click "Log in to your account" when GoogleOpenIDConnect is enabled
This fixes the login link in the OPAC when GoogleOpenIDConnect is enabled. It removes modal-related markup which was causing the link to fail.
[28455] If TrackLastPatronActivity is enabled we should update 'lastseen' field on checkouts
This updates the 'lastseen' date for a patron when items are checked out (when TrackLastPatronActivity is enabled). (The last seen date is displayed on the patron details page.)
[28868] Masthead.inc is missing class name
This patch adds back the class 'mastheadsearch' which was lost during the upgrade to Bootstrap 4 in Bug 20168.
[22801] Advance search yr uses copydate instead of date-of-publication
This fixes the advanced search form in the OPAC and staff interface so that the publication date (and range) uses the value(s) in 008 instead of 260$c when using Elasticsearch.
[28747] Clarify wording on RestrictionBlockRenewing syspref
This clarifies the wording for the RestrictionBlockRenewing system preference to make it clear that when set to Allow, it only allows renewal using the staff interface.
[28567] Pick-up location is not saved correctly when creating a new library
This fixes an issue when adding a new library - the pick-up location was always saving as "Yes", even when no was selected.
[28704] Library MARCOrgCode field needs maxlength attribute
This fixes an error that occurs when you enter a "MARC organization code" in the form for adding and editing libraries. With this change the input field is limited to 16 characters.
[28689] Extra %s in alert message when saving an item
This removes an unnecessary %s in the alert message when there are errors in the cataloging add item form (for example when mandatory fields are not entered).
