42498 Accessibility - Page tabs/pagination on results in opac produces accessibility error "Aria state or property has invalid value"
Sponsored by Athens County Public Libraries
This fixes a 500 page error[1] when creating a suggestion in the staff interface if: - the EmailPurchaseSuggestions system preference is set to "email address of library", and - the library for acquisition information is set to "Any".
[1] Can't call method "inbound_email_address" on an undefined value at /kohadevbox/koha/Koha/Suggestion.pm line 107
This fixes entering suggestions using the staff interface. When making a suggestion the default library selected was "Any". The default library is now the current library you are logged in as.
After creating a suggestion, the staff patron is now redirected back to the patron's purchase suggestion page. Previously, they stayed on the list of suggestions on the suggestion management page in acquisitions.
(This fixes an error introduced by Bug 39721 - Remove GetSuggestion from C4/Suggestions.pm, added to Koha 26.05 and 25.11.)
41705 Popup blockers may be triggered by options to automatically display payment receipt for printing after making a payments

This fixes the "Staged & ready (0)" tab for curbside pickups (Circulation > Holds and bookings > Curbside pickup) so that it uses "and" instead of "&" in the table title, as per the terminology guidelines (when CurbsidePickup is enabled).
This fixes indexing of records, so that when a new title is added in the ERM module (ERM > eHoldings > Local > Titles) and 'Create bibliographic record' is selected, the new record can be found when searching.
This fixes the labels for facets in the OPAC. Customized facets generated from mappings.yaml were displayed with the technical type_id instead of the proper label.
For example, for a facet defined as "su-gen" with a label of "Genre/Form", "su-gen" was used as the label instead of "Genre/Form".
(This is related to Bug 25314 - Make OPAC facets collapse, added to Koha 26.05.00,25.11.04.)
42154 Bug 38714 hid the "New match check" link in record matching rules
