Koha 20.11.08 is a bugfix/maintenance release.

It includes 19 bugfixes.

System requirements

You can learn about the system components (like OS and database) needed for running Koha here: https://wiki.koha-community.org/wiki/System_requirements_and_recommendations

Critical bugs fixed


  • [28586] Cannot resolve a claim

    This fixes an issue with the ‘Returned claims’ feature (enabled by setting a value for ClaimReturnedLostValue)- resolving returned claims now works as expected.

    Before this fix, an attempt to resolve a claim resulted in the page hanging and the claim not being able to be resolved.


  • [28523] Patrons with the most checkouts (bor_issues_top.pl) is failing with MySQL 8
  • [28524] Most-circulated items (cat_issues_top.pl) is failing with MySQL 8

Other bugs fixed


  • [28476] Update info in docs/teams.yaml file


  • [28513] Analytic search links formed incorrectly
  • [28542] Move new authority from Z39.50/SRU to a button

    This makes the layout for creating new authorities consistent with creating new records – there is now a separate button ‘New from Z39.50/SRU’ (rather than being part of the drop-down list).

Fines and fees

  • [28344] One should be able to issue refunds against payments that have already been cashed up.


  • [28582] Can’t enqueue letter HASH(0x55edf1806850) at /usr/share/koha/Koha/ArticleRequest.pm line 123.


  • [28388] Search result set is lost when viewing the MARC plain view (opac-showmarc.pl)
  • [28422] OPAC MARC detail view doesn’t correctly evaluate holdability

    In the normal and ISBD detail views for a record in the OPAC the ‘Place hold’ link only appears if a hold can actually be placed. This change fixes the MARC detail view so that it is consistent with the normal and ISBD detail views. (Before this, a ‘Place hold’ link would appear for the MARC detail, even if a hold couldn’t be placed, for example if an item was recorded as not for loan.)

  • [28545] Noisy uninitialized warn at opac-MARCdetail.pl line 313

    This removes “..Use of uninitialized value in concatenation (.) or string at..” warning messages from the plack-opac-error.log when accessing the MARC view page for a record in the OPAC.

Searching – Zebra

  • [21286] Advanced search for Corporate-name creates Zebra errors

    This fixes the advanced search in the staff interface so that searching using the ‘Corporate name’ index now works correctly when the QueryAutoTruncate system preference is not enabled. Before this a search (using Zebra) for a name such as ‘House plants’ would not return any results and generate error messages in the log files.


  • [28280] Item types configuration page doesn’t use Price filter for default replacement cost and processing fee

    This fixes the display of ‘Default replacement cost’ and a
    ‘Processing fee (when lost)’ when adding item types so that amounts use two decimals instead of six.

  • [28423] JavaScript error on MARC modifications page

    This patch makes a minor change to the MARC modifications template (Staff interface > Administration > MARC modification templates) so that the “mmtas” variable isn’t defined if there is no JSON to be assigned as its value.

  • [28427] Terminology: Shelf should be list
  • [28522] Correct eslint errors in staff-global.js

Test Suite

  • [28479] TestBuilder.pm uses incorrect method for checking if objects to be created exists


  • [27929] Regex option in item batch modification is hidden for itemcallnumber if 952$o linked to cn_browser plugin
  • [28191] Update wording on batch patron deletion to reflect changes from bug 26517
