Changes & Improvements

  • Changed ticket zoom information widget to count only open tickets with the same customer when Ticket::Frontend::ZoomCustomerTickets is enabled.
  • Increased length of the password column for users, customer_user, and mail_account.
  • Improved handling of read-only fields for CustomerUser::DB and CustomerCompany::DB backends.

Bug Fixes

  • Fixed: Znuny redirects after login to the default view even when an ExternalURL parameter with an Action is encoded in the link.
  • Fixed: TemplateGenerator broken when using RichText.
  • Fixed: Customer interface PopupClose function loaded agent interface header/footer, referencing unsupported features. Added CustomerPopupClose function.
  • Fixed: The tags <OTRS_TICKET> and <OTRS_MERGE_TO_TICKET> could only be used once in Ticket::Frontend::AutomaticMergeText due to missing 'global' flag. Thanks to Tim Püttmanns (@tipue-dev), maxence (PR#753).
