[30997] "CGI::param called in list context" warning in detail.pl flooding error log
This fixes the cause of "CGI::param called in list context from" warning messages that appear in the log files when viewing record detail pages in the staff interface.
[30786] Capitalization in (Opac)AdvancedSearchTypes
This fixes the descriptions for the AdvancedSearchTypes and OpacAdvancedSearchTypes system preferences - sentence case is now used for "..Shelving location..".
[30234] Serial local covers don't appear in the staff interface for other libraries with SeparateHoldings
This fixes the display of item-specific local cover images in the staff interface. Before this, item images were not shown for holdings on the record's details view page.
[31005] Cannot edit patrons in other categories if an extended attribute is mandatory and limited to a category
This fixes an error when a mandatory patron attribute limited to a specific patron category was causing a '500 error' when editing a patron not in that category.
[30883] Authorities merge is limited to 100 biblio with Elasticsearch
This fixes the hard-coded limit of 100 when merging authorities (when Elasticsearch is the search engine). When merging authorities where the term is used over 100 times, only the first 100 authorities would be merged and the old term deleted, irrespective of the value set in the AuthorityMergeLimit system preference.
[30958] OPAC Overdrive search result page broken for translations
Sponsored by Melbourne Athenaeum Library, Australia
[28355] Add warning note about Email SMS driver option for SMSSendDriver
This updates the text for the SMSSendDriver system preference. The Email SMS driver option is no longer recommended unless you use a dedicated SMS to Email gateway. Many mobile providers offer inconsistent support for the email to SMS gateway (sometimes it works, and sometimes it doesn't), which can cause frustration for patrons.
[30989] Tags with some special characters are not encoded right
This fixes tags with special characters (such as +) so that the searching returns results when the tag is selected (from the record detail view in the OPAC and staff interface, and from the search results, tag cloud, and list pages in the OPAC).
The Koha manual is maintained in Sphinx. The home page for Koha documentation is
