Consistently use find_by_identifier for authentication.
40811 Enhance Koha::File::Transport API
This enhancement introduces a modernized dual API design for Koha’s file transport system, making it easier for developers to work with FTP, SFTP, and local file operations.Key ImprovementsSimplified API (Recommended)
– Automatic connection management – no need for manual connect() / disconnect() calls
– Per-operation directory control via options hashref
– Stateless operations safe for concurrent usage# Simple one-line operations
$transport->upload_file($local, $remote, { path => ‘/custom/’ });
$transport->download_file($remote, $local);
$transport->list_files({ path => ‘/incoming/’ });

Traditional API (Still Supported)
– Manual connection and directory management when needed
– Ideal for multiple operations in the same directory
– Full backward compatibility maintained

# Explicit control when needed
$transport->change_directory(‘/work/’);
$transport->upload_file($local, ‘file1.txt’);
$transport->upload_file($local, ‘file2.txt’);

Standardized Architecture
– Consistent template method pattern across all transport types (SFTP, FTP, Local)
– Clear separation between public API and protocol-specific implementation
– Improved authentication handling with fixes for password-less connections

This is an internal API enhancement that improves code maintainability and developer experience without affecting end-user functionality.
40993 Do not allow direct calls of value_builder scripts
This report adds an Apache RewriteRule to prevent hitting cataloguing value_builder scripts (aka framework plugins) directly. They are supposed to be called only via plugin_launcher.pl.

Cataloging

Enhancements

17387 Add an undelete feature for items/biblios
When a bibliographic record or item is deleted in Koha, the data is moved to the
deletedbiblio, deletedbiblioitems, and deleteditems tables rather than being
permanently removed. This new feature exposes those tables through a dedicated staff
interface and REST API, enabling authorised users to restore that data back into the
active catalogue.

New Features
- A Restore Deleted Records page is accessible from the Cataloguing module home page,
  presenting two tables: one for deleted bibliographic records and one for deleted items.
- Each table displays key identifying information such as biblio ID, title, barcode, and
  the date the record was deleted.
- A date range filter in the sidebar allows staff to narrow results by deletion date.
- Restoring a deleted item whose parent bibliographic record is also deleted will
  present a warning modal, prompting the user to restore the bibliographic record first.
- Restoring a deleted bibliographic record opens a modal listing any associated deleted
  items, with checkboxes allowing the user to select which items (if any) to restore
  alongside the bibliographic record.
- Restored records are automatically re-indexed in the search engine (Zebra /
  Elasticsearch) upon restoration.
- Restore actions are written to the action log (RESTORE action for both biblios
  and items), providing an audit trail.
- Library group membership is taken into account during permission checks, so staff are
  only able to restore records within their permitted scope.
  
  New REST API Endpoints
New endpoints have been added to the Koha REST API to support programmatic restoration
of deleted records:
- POST /api/v1/deleteditems/{item_id}/restore — restore a single deleted item
- POST /api/v1/deletedbiblios/{biblio_id}/restore — restore a single deleted
  bibliographic record
- GET /api/v1/deleteditems — list deleted items (supports embedding associated biblio
  data and pagination headers)
- GET /api/v1/deletedbiblios — list deleted bibliographic records (supports embedding
  associated deleted items)
  
  New Permission
A new restore_deleted_records permission has been added as a child of the
Cataloguing permissions group. Users must be granted this permission to access the
Restore Deleted Records page and to use the restore API endpoints.

Important Notes
- Restoration is only possible for records still present in the deleted records tables.
  Data in related tables (e.g. link tracker, holds history) that was cascade-deleted when
  the record was removed cannot be recovered by this tool.
- A restored record will be re-inserted with its original biblio/item ID where possible.
- This feature does not constitute a full “soft delete” or undo system — it is a targeted
  recovery tool for data held in Koha’s existing deleted-record tables.

32773 Have the ability to have more than 1 Fast Add framework

This enhancement adds the ability for libraries to use multiple bibliographic frameworks for Fast add.

Administrators with the manage_marc_frameworks permission can now enable MARC bibliographic frameworks to be used as Fast add frameworks.

Library staff with the fast_cataloging permission will be able to create and edit Fast add enabled bibliographic records. They will be able to create items for Fast add enabled records and edit the attached items if allowed by library or library group.

A Fast add badge will be displayed in the details of Fast add enabled bibliographic records.

33857 Reduce and resize local cover images

Previously, uploading a JPEG cover image to Koha’s local cover image store caused the file to be re-encoded as PNG, increasing file sizes by up to 10×. A 170 KB JPEG would be stored as ~930 KB.

After this fix, images are stored in their original format. The same image is now stored at ~92 KB — roughly half the original size, with no quality loss.

This affects all installations using the LocalCoverImages system preference.
39418 Add authorized value lists for MARC21 RDA Carrier, Content, and Media Vocabularies
This enhancement adds authorized value lists for use in MARC21 tags 336 – Content Type, 337 – Media Type, and 338 – Carrier Type, subfields $a and $b. Note: Manual updates are required to your frameworks to link the subfields to the authorized value lists.

The six new authorized value lists:
- RDACARRIER
- RDACARRIER_CODE
- RDACONTENT
- RDACONTENT_CODE
- RDAMEDIA
- RDAMEDIA_CODE

40031 Creation of a new MARC modification template should redirect to have the template ID in the URL

This updates the URL when adding a new MARC modification template (Cataloging > Batch editing > MARC modification templates). It adds the template ID to the URL so that you can directly link to the template.

Previously, you had to click Edit actions from the list of templates, and couldn’t directly link to the template to see the actions:
– Previous URL after adding a template:
STAFF-INTERFACE-URL/cgi-bin/koha/tools/marc_modification_templates.pl
– New URL after adding a template:
STAFF-INTERFACE-URL/cgi-bin/koha/tools/marc_modification_templates.pl?template_id=(template_id)&op=select_template

40633 Add keyboard shortcut to advanced cataloging editor for fixed length field plugins

This enhancement adds a keyboard shortcut to the advanced cataloging editor to open the value builder plugins for the MARC leader, 006, 007, and 008 fields. This shortcut defaults to Control-Shift-H but can be customized as desired.

40841 Limit z39.50 targets to specific libraries

This enhancement adds the option to limit the Z3950/SRU targets to specific libraries.

Within larger systems, catalogers at individual library may have different z39.50 targets that they prefer to use or are allowed access to.
41060 Add a value_builder to check if ISSN is valid
This enhancement adds a new cataloging plugin (value builder) for validating ISSNs. If you enter an invalid ISSN, a browser pop-up window warns that the ISSN is invalid, but you can ignore this (the field is highlighted in yellow) and still save the record.For new installations, the validate_issn.pl plugin is added to the bibliographic frameworks by default for 022$a (MARC21) or 011$a (UNIMARC).For existing installations, update your frameworks manually.
41170 Highlight previously edited item on add items page
This patch adds highlighting of the most recently edited/added item on the ‘add items page’
The feature allows catalogers to identify recent item and confirm their edits or compare to other items in the catalog.
41902 Allow configuration of bibliographic information to be shown on new record duplicate check
This enhancement adds a way to display more bibliographic information when Koha suspects a newly-created bibliographic record may be a duplicate of an existing record. This is done through “Tools” > “Additional content” > “Record display customizations”, using the new display location of StaffDuplicateCheckPage. Information to be displayed is defined in TemplateToolkit and styled with HTML. Available data includes the contents of the biblio table and the full MARC record.

Circulation

Enhancements

7376 Transfer limits should be checked at check-in

This patch introduces new controls to prevent a check-in at a library where transfer rules would forbid the item transfer back to this item’s home/issuing library.

For items set to ‘float’ transfer rules are not set as the check-in would not trigger a transfer.

Sponsored by National Library of Finland
16131 Error messages for library transfers show with bullet points

When transferring items (Circulation > Transfers > Transfer), any error messages are shown as a bulleted list in one alert box.

If there is only one error, it looks a bit odd having a bulleted list with only one item.

With this enhancement, each error message is now shown in its own alert box.

23415 Notify patron fines when renewing
It was possible to renew items for patrons who had fines over the accepted limit on the renew item page or from their list of checkouts.

This enhancement adds a new system preference, AllowFineOverrideRenewing, to allow staff to renew items for patrons with fines greater than value in FineNoRenewal (previously OPACFineNoRenewals).

New features
- New system preference AllowFineOverrideRenewing. It allows staff to renew items for patrons whose fines are over the amount set in the FineNoRenewals system preference. Otherwise, renewing is prevented. If renewing items is allowed, staff are still required to confirm if they really want to renew items for the patron.
Changes made to system preferences and API endpoints
- These system preferences were renamed as they are now also used in the staff interface (not just the OPAC):
  - OPACFineNoRenewals was renamed FineNoRenewal.
  - OPACFineNoRenewalsIncludeCredits was renamed FineNoRenewalsIncludeCredits.
  - OPACFineNoRenewalsBlockAutoRenew was renamed FineNoRenewalsBlockAutoRenew.
- Adds support to the REST API renewal endpoints for the AllowFineOverrideRenewing functionality.
Important notes
- There were several places in the code where the auto-renewal error code was written as “auto_too_much_oweing” instead of “auto_too_much_owing”.
- The same typo was also present in example notices templates, and possibly in notice templates saved in the database.
- The typo is automatically fixed with a database update.

26993 Allow StoreLastBorrower to retain a locally-defined number of previous borrowers

This enhancement expands the StoreLastBorrower system preference to allow for the retention of a locally defined number of previous borrowers for a given item. This enhancement also introduces a mechanism that will delete any extra borrowers stored in the items_last_borrower table that exceed the number set in the StoreLastBorrower system preference.
28530 Allow configuration of floating limits by item type
This enhancement adds the ability to define and enforce a maximum number of items per item type to be held at each library when items are allowed to float. This feature is enabled with the UseLibraryFloatLimits system preference. Float limits are defined within Administration. Items checked in at a library that has met its float limit for that item type will be transferred to the branch with the lowest ratio of held items to allowed items.
30331 Allow RenewalPeriodBase behavior to differ between manual and automatic renewals
This patchset splits the RenewalPeriodBase system preference into two separate system preferences so the renewal base period can be controlled separately for for manual and automatic renewals. The new system preferences are ManualRenewalPeriodBase and AutomaticRenewalPeriodBase.
32682 Add permission for viewing patron reading history
This enhancement adds a new permission for viewing parton’s reading history. ( view_checkout_history )
Now when intranetreadinghistory is enabled staff must also have the specific ‘view_checkout_history’ permission in order to view a patron’s reading history. With intranetreadinghistory turned off the no users are able to view patron’s reading history.
37707 Lead/Trail times should work in combination
37966 When overriding a hold to renew a book the due date becomes “now” if not specified
39802 Add CircControl equivalent system preference for lost item fees and actions

This enhancement adds a new system preference: LostChargesControl which is used to determine the branch that is used to look up the circulation rule for charging lost fees when an item is marked lost.

Choices are:
library the item is from (follows HomeOrHolding)
library the patron is from
library you are logged in at

Currently this is only used by the longoverdue cronjob. Selecting “library you are logged in at” will cause the cronjob to cancel as there is no branch – this mimics current behavior, but is more verbose.

40364 Add permission for viewing patron holds history

This enhancement adds a new permission for viewing parton’s hold history. ( view_holds_history )
Now when IntranetReadingHistoryHolds is enabled staff must also have the specific ‘view_holds_history’ permission in order to view a patron’s hold history. With IntranetReadingHistoryHolds turned off the no users are able to view patron’s hold history.
41134 Add table settings to transfers

This enhancement adds standard table settings to the transfers table (Circulation > Transfers > Transfer). This includes options to change the columns shown, export data, and to configure the default table settings.

41338 Hold found dialog does not show item home and check-in libraries
41539 Include item barcode in waiting hold message on patron record

This enhancement adds the item barcode to the holds waiting information on a patron’s check out and details page.

This makes it easier for circulation staff to copy the barcode to check the item out when a patron picks it up (where this is the library workflow and a self-service option is not available.

Before: Title (Item type), Author. Hold place on DD-MM-YY
After: Title (Item type), Author. (Barcode) Hold place on DD-MM-YY

Command-line Utilities

Enhancements

23260 Anonymize (remove) patron data from items_last_borrower

This enhancement allows the automatic deletion of data from the items_last_borrower table. This data is generated based on the StoreLastBorrower system preference. Deletion of this data performed by the new cronjob anonymize_last_borrowers.pl, with its behavior governed by the new system preferences AnonymizeLastBorrower and AnonymizeLastBorrowerDays. When the cronjob is run, entries in items_last_borrower are anonymized if older than the number of days defined in AnonymizeLastBorrowerDays.
33308 Add ability to to use SFTP with runreport.pl

38549 Make create_superlibrarian.pl script accept a name parameter

This enhancement enables the user to supply a surname parameter when creating a superlibrarian user via the commandline script create_superlibrarian.pl. Koha patrons MUST have a name, so if no surname is provided, the userid will be used for the surname instead.

41062 Expand cronjob erm_run_harvester.pl with parameter for providers

This enhancement adds a new option to define specific providers in the cronjob erm_run_harvester.pl that are used to run the harvesting for COUNTER Reports in the ERM module.
Use parameter –provider-id or -p
The parameter provider-id is repeatable.
If the parameter for provider-id is not used all active providers will be harvested (as before).
The script will check if these providers are active (as before).

The database data types for these fields are tinytext in the borrowers table and varchar(10) in the borrower_modifications table:
- streetnumber (a patron’s main address street number field)
- B_streetnumber (a patron’s alternate address street number field)
This enhancement updates the borrower_modifications table so that the fields are now tinytext, consistent with the borrowers table.

New features

39320 Create a ‘landing page’ for ERM
This adds a customizable landing page to the ERM module. Staff members can remove, add, and reorganise landing page “widgets” to customize the landing page layout to suit their needs (all widgets are shown by default):
- Counts: shows the number of ERM related resources such as agreements, licenses, local packages, local titles, etc.
- Licenses needing action: shows licenses that need action – it filters licenses by status and end date (this is configurable from the settings menu item for the widget).
- Run eUsage report: lets you select a saved eUsage report to run.

Fines and fees

Enhancements

35612 Record branch context in accountlines.branchcode for OVERDUE, LOST, and PROCESSING fees

This enhancement allows the optional recording of the branch used when generating an accountline.

For OVERDUE fees, the branch chosen by CircControl will be reflected here. For LOST and PROCESSING fees, the branch chosen by LostChargesControl will be reflected here.

This development will allow librarians to reference charges against the circ rules to determine which branches rule was applied when creating a fine.
36506 Processing fee should be configurable by library

This enhancement adds a new section to the Circulation and fines rules page, and allows the configuration of processing fees per branch and itemtype.

Following the LostChargesControl syspref, the rule will be chosen based on the branch selected and items will be charged the corresponding processing fee when marked lost if there is one defined.

40255 Allow custom debit descriptions

This patchset allows for the ability to set custom debit descriptions via Notices and Slips by adding a new module called “Debit description (custom)” to notices/slips.. By using a Debit description (custom) notice/slip with the same name as a debit type, a custom debit description will be used instead of the default.

Hold requests

Enhancements

3492 Move hold fee setting into circulation rules
Hold fees can now be configured through the circulation rules matrix, providing much more granular control over hold charges based on patron category, item type, and library combinations.

Previously, hold fees (reservefee) could only be set at the patron category level in the patron category administration. This enhancement integrates hold fees into the main circulation rules system, where they follow the standard rule hierarchy with automatic fallback handling.

Key changes:
- Hold fees can now be set for specific combinations of patron category, item type, and library
- The deprecated reservefee field has been removed from patron categories
- Hold fee configuration appears as a new column in the circulation rules matrix
- Hold fees follow the same rule precedence as other circulation rules (most specific rule wins, with fallback to broader rules)
For administrators:

After upgrading, you may want to review your circulation rules and update hold fees where appropriate. Any existing hold fees previously set at the patron category level will have been migrated to the circulation rules.

40435 Allow CanBookBeRenewed to consider future holds

Historically, renewals are not blocked for future holds (which are only possible when enabled). This report adds a new preference FutureHoldsBlockRenewals to override that behavior. If you enable it, renewals are blocked by future holds when they are not further away than the threshhold used for Holds to Pull in preference ConfirmFutureHolds.
40769 Highlight hold fees when placing a hold from the staff interface
This enhancement adds hold fee information display in the staff interface’s hold
request interface, bringing it to feature parity with the OPAC.The OPAC already shows patrons the fee that will be charged for placing
a hold, but the staff interface did not display this information when staff
place holds on behalf of patrons. This creates a transparency gap where
staff cannot inform patrons about potential charges.
41957 Hyperhold/hold group information should show on ‘Hold found’ modal
This enhancement adds a notification to the hold found modal when the hold to be filled is part of a group. The modal will include the message “part of a hold group” and a link to the holds table in the patron’s account.
41983 Holds queue should show when holds are part of a group
This adds “(part of a hold group)” to the holds queue (under the title in the title column), when hold groups are enabled (DisplayAddHoldGroups system preference).

This enhancement fixes the staff interface home page so that the “Self-registrations from” alert is only shown if the staff patron has the correct permissions. Before this, the alert was shown when the staff patron didn’t have any borrower permissions.

40794 Add an id to the div containing payments tabs

An id=”account-tabs” attribute has been added to the account/payment tab navigation (Transactions, Make a payment, Create manual invoice, Create manual credit). This allows for easier customization and targeting with CSS/JS without conflicting with the global toptabs navigation.
41411 Streetnumber field is limited to 10 characters despite being tinytext
The input form for a patron’s main and alternative address street number fields are limited to 10 characters, even though the underlying database field can have up to 255 characters.This enhancement removes this 10-character limit, which makes it more useful where house names are used instead of house numbers.
41749 Add patron consent status display to staff patron detail page
Adds a “Consents” section to the staff patron detail page. It shows the patron’s privacy consent status (when PrivacyPolicyConsent
is enabled) and any plugin-defined consent types.Each consent displays with visual status indicators:
– Green checkmark with timestamp when consent was given
– Red X with timestamp when consent was refused
– Gray “Not specified” when no consent recorded
41814 Limit the maximum age for patron categories without a specified range

This patch adds a new system preference PatronAgeRestriction, which acts in the same way PatronSelfRegistrationAgeRestriction (a restriction on the maximum age of a borrower), except for the intranet. It will also act as the maximum age restrictor on the OPAC, in the event that the PatronSelfRegistrationAgeRestriction is not set.

Plugin architecture

Enhancements

36542 In C4/AddBiblio, plugin hook after_biblio_action is triggered before the record is actually saved

This bug fix moves when the after_biblio_action plugin hook is triggered so the record can be saved before the plugin hook is called. This will let the plugin save biblionumbers on newly created records that would otherwise not be generated yet.
39522 Add hooks to allow ‘Valuebuilder’ plugins to be installableSponsored by OpenFifth
40095 It would be beneficial to send the page when calling intranet_js plugin hooks

The get_plugins_intranet_js method now passes the current script name
(controller) to plugins via a ‘page’ parameter, allowing plugins to
determine which page/controller is being displayed.

This will allow plugin authors to only return JS that’s relevant to the
current page when they wish to do so.
40972 New hook: extend MARC filter
42150 Allow plugins to register Vue islands via registerIsland()
The islands module provides Koha’s Vue component architecture but does not expose a public API for external registration. This enhancement enables plugins to contribute Vue islands to the staff interface.
It also lays the groundwork for bug 42189 which allows plugins to create new dashboard widgets.

Reports

Enhancements

39043 Style improvement to guided reports controlsSponsored by Athens County Public Libraries
39164 Add max_statement_time to SQL report queries

This patchset adds the abilty to set a maximum execution time in seconds for SQL report queries. Reports exceeding this limit will be automatically terminated. This is configured in the koha-conf.xml file by setting the report_sql_max_statement_time_seconds parameter. By default this is turned off.
40896 Run report button should be disabled after click
The “Run report” buttons in the guided reports interface are now disabled upon click and display a spinner icon, preventing accidental duplicate submissions that could overload the system. This improvement uses a new reusable throttled button component that automatically re-enables after a configurable timeout and correctly handles browser back-forward cache navigation. The component wraps icons in semantic containers for accessibility (aria-busy) and is designed to be reused across other parts of the staff interface.
41918 Prevent users from running the same report multiple times concurrently
41919 Limit number of current reports a single user can run simultaneously
42190 Add datatables to reports
This enhancement allows report results to be viewed with the DataTables feature used elsewhere in Koha. DataTables allows sorting by any column in the results as well as dynamic filtering. Export options within the DataTables view include a new Copy option and export data respecting the user’s current sorting and filtering.
42406 Create permission to allow user to delete only their own reports

SIP2

Enhancements

41214 Cash register should only show if UseCashRegisters sys pref is enabled

This change turns the display of the ‘cash register’ field in SIP2 accounts to become conditional depending on whether the UseCashRegisters sys pref is enabled or not.
For developers: This changes the hideIn option for VueJS framework resources, now allowing it to be a callback function which is checked in real-time, dictating whether a field is displayed or not.
41311 Add ability for SIP to send patron home library ( branchcode ) in AO field
41383 SIP2 server does not search patrons by unique patron attributes (alternate IDs unusable in SIP2)

Searching

Enhancements

36920 Greater/less than search option on item search page to Barcode-drop-down menu

This enhancement adds greater than and less than search options on item search page field drop-down menu. With them staff can search e.g. items which have release year starting from specific year.

Searching – Elasticsearch

Enhancements

21820 Zebraqueue should not be added to when only Elasticsearch is used

We added a new syspref “ElasticsearchEnableZebraQueue”. If disabled, no data will be written to the zebraqueue table, because usually when using Elasicsearch you don’t need to also run Zebra.

But if your workflows require changed biblio/auths to show up in the zebraqueue table, set the syspref to “enable”. When upgrading, the old behavior will be kept, i.e. the syspref is set to “enable”. New installations will default to “disable”.
22639 Ability to export Elasticsearch mappings and facets settings
This enhancement adds an ‘Export mappings’ button to the Elasticsearch mappings configuration page to download the current search field mappings as YAML.
36550 koha-elasticsearch commit default should be configurable
You can now set custom defaults for koha-elasticsearch in /etc/default/koha-common. You can still override the defaults using the command line.
36849 Add more tags to Elasticsearch mapping for title, title as phrase

This enhancement adds these fields to the ‘title’ index for new installations using Elasticsearch: 440$a, 600$t, 800$t, 810$t, 830$n$p. This makes records with information in these fields findable in the staff interface and OPAC, and in the advanced search, when using the ‘Title’ and ‘Title as phrase’ options.

Note: Existing installations will need to either manually add these, or reset the mappings.

23909 SCO allows to check out items with Waiting state if AllowItemsOnHoldCheckoutSCO

This enhancement extends the options in the system preferences AllowItemsOnHoldCheckoutSCO and AllowItemsOnHoldCheckoutSIP. When a patron attempts via the web-based self-checkout or SIP to check out an item on which another patron has a hold, libraries now have the option to block all checkouts, allow the checkout if the hold is pending, or allow the checkout if the hold is pending or waiting. The new system preference AllowHoldCheckoutOverride governs whether or not staff with sufficient permissions should be able to check out on-hold items to other patrons via the staff client.

This enhancement adds a new system preference SeparateHoldingsByGroup. When this preference is enabled and the logged-in library is part of a library group marked Use for staff search groups, the holdings table will include a tab listing all items with a homebranch within that group. When SeparateHoldings is also enabled, the Other holdings tab will only include items not owned by either the logged-in library or a library sharing a group with the logged-in library.
36698 Display ‘diff’ nicely in action logs
This enhancement adds styling to the diff column in the action logs to make it more human readable.
38728 Add option to automatically trigger cashup summary modal after cashup
This enhancement automatically displays the cash register summary in a pop-up window after recording a cashup (from both the individual cash register details page and the cash registers summary page).
38946 Add serial enumeration to inventory table
This change adds a “Serial enumeration / chronology” column into the inventory results. This is particularly useful when doing inventory/stocktake with serials which share the same call number but have different volume numbers. This new column can be hidden by clicking “Columns” and hiding it or going into table settings.
39142 Add debug permission to allow user to toggle JS and CSS customizations on/off
This fix adds GUI controls to disable custom CSS and JS on the page. It also includes a system preference, user flag, to control managing this along with updates to permissions for being able to do this. This works alongside the pre-existing url parameters to disable custom css and JS in the page.
40816 Upgrade DataTables from 2.1.8 to 2.3.4
This enhancement upgrades the DataTables JavaScript library from version 2.1.8 to 2.3.4.This brings in upstream fixes and improvements released since 2.1.8, including bug fixes and general stability updates.No functional changes are expected in Koha beyond those provided by the updated DataTables library.
40933 Add SMS support under Add message feature

For those using the MySQL database. Starting from MySQL 5.7.31 and MySQL 8.0.20, mysqldump requires the PROCESS privilege to access tablespace metadata by default. Without this privilege, backup operations fail with permission errors.

This fixes this issue by adding the –no-tablespaces flag to the dbflag variable. This prevents mysqldump from attempting to access tablespace metadata, allowing backups to complete successfully without requiring the PROCESS privilege.

This fixes the UNIX user/group ownership of the log files intranet-error.log and opac-error.log inside /var/log/koha/<instance>/.
Previously, running koha-create --request-db followed by koha-create --populate-db would result in the two log files being owned by root/root.

41145 Logging patron attributes logs even if there’s no changes (26.05.00,25.11.01)
This prevents misleading patron attribute modification logs, when a library batch imports patrons with the BorrowersLog system preference set to ‘Log’. It now correctly only shows a log entry when a patron attribute value is changed.

Example:
- Before the change: for an existing patron with a patron attribute of INSTID:1234, with a re-import the log shows { “attribute.INSTID” : { “after” : “1234”, “before” : “” } }, even though there is no change to the patron attribute.
- After the change:
  . No log entry is shown if there is no change to the patron attribute.
  . If there is a change to the patron attribute (for example, changed to 5678 on a re-import), it is now correctly shown – { “attribute.INSTID” : { “after” : “5678”, “before” : “1234” } }

35380 PUT /biblios/:biblio_id doesn’t apply record overlay rules (26.05.00,25.11.05)
This fixes API requests that update a bibliographic record (PUT /biblios/:biblio_id) so that they apply the record overlay rules if defined in Administration > Catalog > Record overlay rules > Module = source.The predefined values for record sources are:
– batchmod (Batch record modification)
– intranet (Staff interface MARC editor)
– batchimport (Stage MARC import)

– bulkmarcimport (Bulk import command line script)
– import_lexile (Lexile.com scores from CSV using the command line script)
and can be expanded in Administration > Catalog > Record sources.
41614 additional_contents REST endpoint broke the display location filter (26.05.00,25.11.05)
This fixes a regression that resulted in an empty list in the “Display location” filter in the sidebar for Tools > Additional tools > HTML customizations. Only All, OPAC, and Staff Interface options were shown in the dropdown list, instead of the full list of display locations.(Regression caused by Bug 39900 – Add public REST endpoint for additional_contents, in Koha 25.11 and 25.05.)
42053 Bug 37893 DBUpdate does not always add the new userflags/permissions (26.05.00,25.11.05)
This patch adds the ‘sip2’ user flag to systems on which it does not exist. This flag was introduced in Bug 37893 but due to an error in the upgrade script it was not added to systems without existing SIP configuration.

This fixes editing and showing OpacLibraryInfo HTML customizations information in the staff interface and OPAC:
1. Staff interface:
  - When editing a library (Koha administration > Libraries > Actions > Edit)
    . the links to edit OpacLibraryInfo entries for the OPAC information field are now correct (previously, they may have linked to an incorrect HTML customization)
    . if there is more than one OpacLibraryInfo entry, all entries are now shown (only one entry was shown previously)
  - When viewing library information (Koha administration > Libraries > Name > [click library name]), all the OpacLibraryInfo entries are now shown
2. OPAC:
  - All the entries for a library (including any ‘All libraries’ entries for OpacLibraryInfo) are now shown on the library information page (from the ‘Libraries’ link under the quick search bar)
  - In a record’s holdings table, the pop-up window when you click on the current library for an item now correctly shows all entries

41682 Syspref discrepancies between new and upgraded installs (26.05.00,25.11.03)
This fixes several system preferences discrepancies and adds tests, including:
- Setting options to NULL when options=””
- Fixing the explanation when different
- Fixing the wrong order (some rows had options=explanation)
- Fixing the wrong type “Yes/No” => “YesNo”
- Removed StaffLoginBranchBasedOnIP: both StaffLoginLibraryBasedOnIP and StaffLoginBranchBasedOnIP are in the database for upgraded installs
- Adding a description for ApiKeyLog
- Fixing ‘integer’ vs. ‘Integer’ inconsistency
- Fixing ‘cancelation’ typo
- Improving the tests:
  - Compare sysprefs.sql and the database content for options, explanation and type
  - Catch type not defined
  - Catch incorrect YesNo values (must be 0 or 1)
An example where discrepancies have crept in during upgrades includes warnings in the About Koha > System information – the system preferences had no value (either 1 or 0) in the ‘value’ field:
* Warning System preference ‘ILLHistoryCheck’ must be ‘0’ or ‘1’, but is ”.
* Warning System preference ‘ILLOpacUnauthenticatedRequest’ must be ‘0’ or ‘1’, but is ”.
* Warning System preference ‘SeparateHoldingsByGroup’ must be ‘0’ or ‘1’, but is ”.

41934 Empty table header in course reserves table causes accessibility error (26.05.00,25.11.05)
This fixes an accessibility issue with the course reserves table in the OPAC (OPAC > Course reserves): “Table header text should not be empty”.Previously when responsive table controls were shown for the list of course reserves (a green “+” button is shown when the browser window is narrower and all the columns can’t be displayed), there was no title for the column header with the controls.Now, the column header has the text “Expand” when the responsive controls are shown.

27115 Restarting koha-common fails to restart SIP2 server (26.05.00,25.11.02)
This fixes an issue when stopping and restarting SIP servers using koha-sip – it would sometimes not restart the SIP servers.This was because a restart could attempt the –start command while a previous SIP server was still running. This could result in the SIP server not restarting at all.The fix replaces daemon --stop with start-stop-daemon --stop in the code, to ensure that all the running SIP servers are actually stopped before restarting.

– lodash from ^4.17.12 to ^4.17.23 (MODERATE)
– minimatch from ^3.0.2 to ^3.1.4 (HIGH)Yarn resolutions added to pin secure versions of transitive dependencies:
– form-data ^2.5.4 (CRITICAL)
– fast-xml-parser ^4.5.4 (CRITICAL)
– braces ^3.0.3 (HIGH)
– qs ^6.14.1 (HIGH)
– serialize-javascript ^7.0.3 (HIGH)

41345 Regression: Clicking the ‘Ignore’ button on hold found modal for already-waiting hold does not dismiss the modal (again) (26.05.00,25.11.01,25.05.09)
This fixes a regression when checking in an item. Clicking the “Ignore” option in the dialog box, when an item already has a waiting status, just reloaded the dialog box. Clicking the “Ignore” option now closes the dialog box and works as expected.
41352 Bookings to Collect Help does not take you to the correct place in the manual (26.05.00,25.11.01)
This fixes the link to the help for the Circulation > Holds and bookings > Bookings to collect page – it now links to the correct place in the documentation, instead of the documentation home page.
41451 Hold history search fails when itemtype column present (26.05.00,25.11.01)
This fixes filtering on a patron’s holds history when AllowHoldItemTypeSelection is enabled. This previously produced a 500 error when searching, but now works as expected.
41456 Item type filter on the hold history view does not work correctly (26.05.00,25.11.01)
This fixes the patron’s holds history table in the staff interface. The search filter now works as expected – using the library name or library code and requested item type name or item type code (when AllowHoldItemTypeSelection is enabled) now work as expected, and the column filters for both of these now use dropdown lists.

41518 “Scheduled for automatic renewal” displays even if patron does not allow automatic renewals (26.05.00,25.11.04,25.05.11)
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.
41788 Make running the holds queue on click optional (26.05.00,25.11.05)
This patch adds a system preference ‘UseHoldsQueueFilterOptions’. When it is enabled it prevents the direct running of the holds queue by clicking on the ‘Holds queue’ links. With it enabled it will present the user with filter options before running the holds queue. This is to prevent excessive running of the holds queue which can cause slowdowns on larger systems.

41097 Deduping authorities script (dedup_authorities.pl) can die on duplicated ids (26.05.00,25.11.04)
This fixes the deduping authorities maintenance script (misc/maintenance/dedup_authorities.pl) so that it now works and displays the output from the merging of authority records as expected.Previously, it seemed to generate duplicate IDs, for example:

Before

41316 Using patron-homelibrary option for overdue notices does not change which rules are used (26.05.00,25.11.04)
41967 cleanup_database.pl ignores integer values for –labels and –cards and defaults to 1 day (26.05.00,25.11.05)
This fixes a bug in the cleanup_database.pl script to delete label batches and patron card batches older than X days. Before this fix, if the –labels or –cards argument was passed in the cronjob, all batches older than 1 day were deleted, regardless of the value passed in the argument.
42273 ‘idenfity’ typo in categories table (26.05.00,25.11.05)
Fixes the spelling in the database comment for the categorycode field (in the categories table): ‘idenfity’ to ‘identify’.
41120 Click on New data provider breaks functionality (26.05.00,25.11.03)
This fixes adding a new data provider after creating a new data provider (ERM > eUsage > Data providers > New data provider).If you created a new data provider, clicked close after the information about the provider was shown, then went to add another new data provider – nothing happened: you got an empty page, and there was an error in the browser developer tools console.

41386 Adding 0.00 as value for “Expired hold charge” in circulation rules can lead to exception Koha::Exceptions::Account::AmountNotPositive (26.05.00,25.11.05)

Using value 0.00 in “Expired hold charge” rule on circulation rules caused Koha to die with exception Koha::Exceptions::Account::AmountNotPositive when expired hold charge was added for patron. This was caused by error in if statement in method Koha::Hold->cancel which allowed value 0.00 to be passed to method add_debit. This method then raised exception since value 0.00 is not positive. This patch fixes the erroneous if statement in method Koha::Hold->cancel.

41267 It should be possible to prevent some itemtypes from filling other biblio level holds (26.05.00,25.11.05)
41335 Toggling the hold options does not always work in opac-reserve (26.05.00,25.11.05)

When DisplayMultiItemHolds is enabled, item selection for specific items is done via checkboxes; no item is preselected unless there is only one. Otherwise an item is selected via radio buttons. The first one is preselected.
41416 Poor performance when clicking ‘Update hold(s)’ on request.pl for records with many holds (26.05.00,25.11.02)
41432 Add prefetch to improve performance of holds page (26.05.00,25.11.01)
This improves the performance of the holds request page for a record in the staff interface.
41801 FixPriority recursive calls for lowestPriority holds can be removed (26.05.00,25.11.05)
This performance update optimizes the C4::Reserves->FixPriority function. Previously, when adjusting holds on a record with many “lowest priority” requests, Koha would use recursive calls that repeatedly touched every hold on the record. This caused significant slowdowns (lag) when managing large hold queues.
41849 Cancelling filled hold from group does not cancel remaining pending holds from group or indicate that it’s a hyperhold (26.05.00,25.11.05)
This patch adds a new option to the modal displayed when checking in an item that is already waiting for a hold. If the hold is part of a group, the modal will offer the option to cancel all holds in the group rather than just the hold for the item that has been checked in.
A new REST API endpoint (POST /patrons/{patron_id}/hold_groups/{hold_group_id}/cancel) has been added to achieve this functionality. The new endpoint will:
-Cancel all holds within a specified hold group.
-Accept a cancellation reason
-Return a 204 on success
-Return a 404 when the hold group cannot found or does not exist.The endpoint requires the ‘reserveforothers’ permission.
41878 No logs for grouping existing holds or ungrouping a hyperhold (26.05.00,25.11.05)
With this patch, Koha will record a holds modification in the action logs each time a hold is grouped or ungrouped.
41880 Logs for moved holds don’t indicate original bib number/item number (26.05.00,25.11.05)
If a record-level hold is moved from one record to another (or an item-level hold is moved from one item to another), and no change was made to the hold before it was moved, there was no way to identify the record or item for the original hold (when HoldsLog is enabled).With this change, both the old record (or item) number and new record number (or item) are now shown in the log viewer Info and Diff columns.This is shown in the diff column as O for the old biblionumber (or itemnumber) and N for the new biblionumber (or itemnumber).Example for the Diff column for a record-level hold that was moved:
- Before (note “O”:”11″ and “N”:11):
  {“D”:{“biblionumber”:{“O”:”11″,”N”:11},”timestamp”:{“O”:”2026-02-28 02:39:44″,”N”:”2026-02-28 02:42:02″}}}
- After (note “N”:11 and “O”:262):
  {“D”:{“biblionumber”:{“N”:11,”O”:262},”timestamp”:{“O”:”2026-02-28 02:54:57″,”N”:”2026-02-28 02:55:18″}}}
Example for the Diff column for a record-level hold that was moved:
- Before (note that no biblionumbers or itemnumbers are shown):
  {“D”:{“timestamp”:{“N”:”2026-02-28 02:51:07″,”O”:”2026-02-28 02:50:00″}}}
- After (note that the new and old biblionumbers and itemnumbers are now shown):
  {“D”:{“biblionumber”:{“O”:139,”N”:255},”itemnumber”:{“N”:563,”O”:296},”timestamp”:{“N”:”2026-02-28 02:59:33″,”O”:”2026-02-28 02:58:34″}}}
- 41956 Show hold_group_id in patron holds table rather than visual_hold_group_id (26.05.00)
- 42147 Action logs for hold creation contain less data (26.05.00,25.11.05)
  Prior to version 25.05.05, the action logs for creating a hold used to show the full hold data in the “info” column, but starting in 25.05.05 the “info” column only shows the hold id, and other hold information is not logged when the hold is created. This restores other hold values to the hold creation action logs, so that libraries can easily look up the starting priority and options that were selected when the hold was first placed.
- 42255 Grouped holds counted inconsistently for circ rules (26.05.00,25.11.05)
  This fixes placing holds when group holds are enabled (DisplayAddHoldGroups system preference), so that a group hold only counts as one hold.
Previously, each hold in the hold group was counted as a hold. So if the “Holds allowed (total)” or “Maximum total holds allowed (count)” circulation and fine rules values were exceeded you would not be able to place additional holds and get a message “Too many holds: [patron name] can place of the requested holds for a maximum of XX total holds.”.

Example: if the total holds allowed is set to 2 and a group hold was placed on two records, this was counted as 2 holds – placing an additional hold would result in the the “Too many holds” message.

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)).

41585 Refunds don’t always appear on the register page (26.05.00,25.11.05)
This patch fixes two issues with cash refunds on the register page:

Previously, in UNIMARC instances, a search for “Corporate Body
Name” authorities (authtypecode ‘CO’) in the OPAC or in the
Staff interface would return “Collective Title” (authtypecode ‘CO_UNI_TI’) authorities as well. This has now been fixed. NOTE: this was a Zebra-only issue, Elasticsearch is not affected.
27826 Self checkout dies on ‘?’ as a barcode (26.05.00,25.11.05)
This fixes the self-checkout feature so that barcodes with characters (such as ? or +) work. Previously, attempting to check out an item with such a barcode resulted in an error page.
41645 Make self-checkout use responsive CSS (26.05.00,25.11.04)
This change fixes the self check-out (SCO) so that it works with responsive CSS, which makes it more mobile friendly. This is especially useful when providing SCO on a tablet.

42200 SelfCheckTimeout being interpreted in milliseconds instead of seconds (26.05.00)
This fixes the timeout for the self-checkout system. The value in SelfCheckTimeout is in seconds, but milliseconds were used in the code. (For example, instead of the timeout happening after 120 seconds (2 minutes) you were logged out after 120 milliseconds!)(This was caused by a change in Bug 38365 – Add Content-Security-Policy HTTP header to HTML responses, added in Koha 26.05.)
36136 Flatpickr allows selecting date from the past on copied serial subscriptions (26.05.00,25.11.03)
36466 Incorrect date value stored when “Published on” or “Expected on” are empty (26.05.00,25.11.03,25.05.09)
Editing a serial and removing the dates in the “Published on” and “Expected on” fields generated a 500 error (Serials > [selected serial] > Serial collection).This fixes the error and:
– Sets the data in the database to NULL
– Shows the dates as “Unknown” in the serial collection table for the “Date published” and “Date received” columns
– Changes any existing 0000-00-00 dates in the database to NULL (for existing installations)
37796 Generated issue has incorrect number in pattern when receiving (26.05.00,25.11.01)
This fixes an issue with incorrect numbering patterns and the next expected issue shown, after a serial is received.Example of an incorrect numbering pattern before this fix:
– Monthly serial received for August 2025 (its status shows as ‘Arrived’ for August 2025).
– The next expected serial was then shown as August 2025 instead of September 2025 (its status was shown as ‘Expected’ with a incorrect numbering pattern of August 2025)

34353 We don’t need ‘SpineLabelShowPrintOnBibDetails’ anymore (26.05.00)
This removes the SpineLabelShowPrintOnBibDetails system preference, as columns shown on the bibliographic details page holding table are customizable using table settings.(Upgrading takes into account the current settings. For, example if SpineLabelShowPrintOnBibDetails was set to show, then it will be visible unless the table setting for spinelabel was set to “Is hidden by default”.)

41484 Wording of ‘On hold’, ‘Booked’, and ‘Recalled’ in issues table can be confusing (26.05.00,25.11.02)
This updates the wording of messages on a patron’s checkouts tab (under the check out and details sections) to avoid confusion when another patron has placed a hold, booking, or recall.Messages changed:
– Recalled => Item recalled by another patron
– Booked => Item booked for another patron
