[29596] Add Yiddish language
This enhancement adds the Yiddish (יידיש) language to Koha. Yiddish now appears as an option for refining search results in the staff interface advanced search (Search > Advanced search > More options > Language and Language of original) and the OPAC (Advanced search > More options > Language).
[28610] Elasticsearch 7 - hits.total is now an object
Sponsored by Lund University Library
This is one of the changes to have Koha compatible with ElasticSearch 7. This one also causes the full end of compatibility with ElasticSearch 5. Users are advised to upgrade as soon as possible to ElasticSearch 7 since version 5 and 6 are not supported anymore by their developers.
[30402] Authority import hanging when replacing matched record
Sponsored by Educational Services Australia SCIS
[29957] Cookies not removed after logout
This patch adds a new config variable to koha-conf.xml called do_not_remove_cookie. By default, all cookies are cleared now. But you could uncomment the KohaOpacLanguage entry to preserve it.
[30159] Fix display of validation of important fields when biblio cataloguing
Sponsored by Education Services Australia SCIS
This patch adds a check for both mandatory and important fields when validating bibliographic records during cataloguing.
[27812] Remove the ability to transmit a patron's plain text password over email
This bugfix/enhancement improves the default security of Koha by removing the pass of the plain text password to the ACCTDETAILS notice on patron creation.
WARNING: You will need to update your notice template if you were relying on
<<borrowers.password>>
in this notice.

Sponsored by Steiermärkische Landesbibliothek
