Koha 25.05.11 is a bugfix/maintenance release.

It includes 1 enhancements, 34 bugfixes and 2 security bugs.

System requirements

You can learn about the system components (like OS and database) needed for running Koha on the community wiki.

Security bugs

• 38414 Reports permissions not properly enforced
• 42361 SQL Injection in reports/catalogue_out.pl via Filter parameter (error-based, triggered when Criteria matches /branchcode/)

Bugfixes

Architecture, internals, and plumbing

Critical bugs fixed

• 41328 All KohaTable tables broken in Vue components
• 42071 Suggestion does not load when viewing the suggestion
  

  This fixes suggestion details not showing when you click the title in the staff interface suggestions management table.

  (Related to changes made by Bug 41857 – Suggestions table actions broken (Update manager and Delete selected), added in Koha 26.05.)

• 42098 EDIFACT edi_cron.pl runs disabled plugins due to bug in Koha::Plugins::Handler::run
  Closes a loophole in our plugin handler that meant that some plugin methods may have run even when the plugin was marked as disabled.

Cataloging

Other bugs fixed

• 41417 500 error when creating new authorized values from additem.pl

Circulation

Critical bugs fixed

• 34000 Don’t allow auto-generated cardnumbers to be re-used, it may give access of services to the next patron created

Other bugs fixed

• 41518 “Scheduled for automatic renewal” displays even if patron does not allow automatic renewals
  

  This change makes the “Scheduled for automatic renewal” text only appear in the renew column of checkouts table in the staff interface and OPAC when the item will actually be considered for automatic renewal.

  The text was showing, even if the item would not automatically be renewed due to automatic renewals being disallowed at the patron level.

  This now matches the criteria that misc/cronjobs/automatic_renewals.pl uses for processing automatic renewals.

• 41886 Biblio::check_booking counts checkouts on non-bookable items causing false clashesSponsored by Büchereizentrale Schleswig-Holstein

Fines and fees

Critical bugs fixed

• 29923 Do not generate overpayment refund from writeoff of fine

Notices

Other bugs fixed

• 41393 Advance notices should set the reply to address

OPAC

Other bugs fixed

• 41558 Broken links to tab on opac-user
  

  This fixes and standardizes links to tabs for the patron summary section in the OPAC (such as Checked out, Overdue, Charges, Holds, and so on).

  In the past, we have used several different ways (some that work, some that don’t) to construct the links to the tabs.

  Now, to directly link to a tab in the summary section, add ?tab=opac-user-* to the URL when you are in the summary section (where * = tab name from the anchor when you hover over the tab, for example checkouts (for Checked out), overdues (for Overdue), fines (for Overdue), recalls (for Recalls)).

• 41970 PA_CLASS does not show in fieldset ID on opac-memberentry.pl

Patrons

Critical bugs fixed

• 42423 Submit button in patron search from header never submits
  

  This fixes the patron search in the staff interface header.

  If the search you enter didn’t show any autocomplete results, clicking the arrow to search didn’t do anything.

  Now, it will use the search you entered and show any results.

Other bugs fixed

• 41675 Username value is ignored in Patron quick-add form
• 41904 “Use of uninitialized value…” warning in del_message.plSponsored by Ignatianum University in Cracow
• 41986 Names in “Contact information” need more clarity
  

  This changes the “Contact information” section on the patron details page (moremember.pl) to:
  – show the “Middle name” field (where it exists)
  – show the “Preferred name” field at the top (where it differs from the “First name”).

Reports

Other bugs fixed

• 41715 Argument “YYYY-MM-DD” isn’t numeric in numeric lt (<)… warnings in issues_stats.pl
  

  Removes the cause of “[WARN] Argument “YYYY-MM-DD” isn’t numeric in numeric lt (<) at /kohadevbox/koha/reports/issues_stats.pl line 224.” warnings from the plack-intranet-error.log when using the from and to date filter in the circulation statistics report in the staff interface.

  This was happening because a numerical comparison was used to compare the dates, instead of a string comparison.

SIP2

Other bugs fixed

• 36752 Remove TODO about missing summary info in the SIP2 code
• 41811 SIP server will inadvertently remove non-alphanumeric characters from the end of a message
• 41818 SIP2 message in AF field should be stripped of newlines and carriage returns

Searching

Other bugs fixed

• 41444 Fetch transfers directly for search results
• 41496 Item search copy sharable link not workingSponsored by Lund University Library

Staff interface

Other bugs fixed

• 41958 Rename BibTex to BibTeX (with a capital X) for the staff interface cart and list download options (to match the OPAC)
  

  This renames BibTex to BibTeX (with a capital X) for the staff interface cart and list download options (to match the OPAC).

• 41976 [Vue] LinkWrapper.vue isn’t scoped properly
• 41989 addbook shows the translated interface
  Fixes an issue with templates that meant incorrect translations could be shown on the addbook page.

System Administration

Other bugs fixed

• 41360 Transport cost matrix assumes all transfers are disabled upon first use
  

  This adds three new toolbar buttons to make batch modifications to the transport cost matrix table easier (when UseTransportCostMatrix is enabeld):

  • Enable all cells
  • Disable empty cells
  • Populate empty cells, with selectable values from 0 to 100

  Templates

Other bugs fixed

• 40787 Plugins buttons misaligned when search box is enabled
• 41838 Fix automatic tab selection on MARC subfield edit pagesSponsored by Athens County Public Libraries
• 42014 Patron lists tab shows blank content when no patron lists exist
