nhaisLOCAL libraries will be upgraded to Koha version 22.11 in the coming months. The exact date for your upgrade will be posted when available in the news area on the left of the staff homepage.
The staff interface has been redesigned for this release. You can take a test drive of the new look at ByWater's demo site. Use bywater for both username and password. The site is refreshed every 3 hours and all changes are reset so play around all you like. Any data added to the site will be deleted.
