System requirements
You can learn about the system components (like OS and database) needed for running Koha on the community wiki.
This patch updates the ILS-DI authorized IPs preference to deny all IPs not listed in the preference.
Previously if no text was entered the ILS-DI service was accessible by all IPs, now it requires explicitly defining the IPs that can access the service.
Upgrading libraries using ILS-DI should check that they have the necessary IPs defined in the system preference.
36049 Rounding prices sometimes leads to incorrect results
This fixes the values and totals shown for orders when rounding prices using the OrderPriceRounding system preference. Example: vendor price for an item is 18.90 and the discount is 5%, the total would show as 17.95 instead of 17.96.

This fixes authentication checking so that the $sessionID is consistently returned (sometimes it was returning the session object). (Note: $sessionID is returned on a successful login, while $session is returned when there is a cookie for an authenticated session.)
37656 XSS in Advanced editor for Z39.50 search results
Sponsored by Chetco Community Public Library
This fixes the hover message when attempting to grant the
superlibrarian
permission (Access to all librarian functions) to a patron. It changes the message to use the correct system preference name "The system preference ProtectSuperlibrarianPrivileges is enabled", instead of "..ProtectSuperlibrarian...".(The message appears over the tick box next to the permission name if the patron attempting to set the permissions is not a super librarian, and the ProtectSuperlibrarianPrivileges is set to "Allow only superlibrarians" - only super librarians can give other staff patrons superlibrarian access.)
37369 Item search column filtering can't use descriptions

31450 HTML customizations and news will not display on OPAC without a publication date
This fixes the display of news, HTML customizations, and pages on the OPAC - a publication date is now required for all types of additional content. Previously, news items and HTML customizations were not shown if they didn't have a publication date (this behavour was not obvious from the forms).

37654 XSS in batch record import for the citation column
Sponsored by Chetco Community Public Library
This fixes the table for the batch patron modification tool (Tools > Patrons and circulation > Batch patron modification). When you scrolled down the page so that table header rows are "sticky", and then scrolled to the right, the table header columns were fixed instead of changing to match the column contents.
