Koha Community Announces 22.11 Release

The Koha Community, home of the world's first free and open-source library system, announced last month that the Koha 22.11 release is available. Koha 22.11.00 is a major release, that comes with 13 new features, 351 enhancements, 3 security fixes, and 551 bugfixes.

Tomas, 22.11 Release Manager, and Software and System Maintainer, commented on the release.

It’s been a particularly busy release with several big challenges. I’m grateful for the chance I had to serve as Release Manager, and for this great community and its members, who invested their time to make this happen.

Special thanks to:

  • Martin
  • Nick, Kyle, and Lucas
  • Katrina
  • Owen
  • the ByWater folks, for all the hugs and support

all of whom have been promptly available to tackle the different problems we faced through this vertiginous cycle.


The Koha Community would like to dedicate the release of Koha 22.11 to Rosalie Blake.

Rosalie was the Head Librarian at Horowhenua Library Trust when Koha was started and without her, Koha would not exist. She was an inspiring leader and innovator and took the risk of her career entrusting Chris, Joanne, Rachel, and Simon to deliver the original project that became the international sensation we all know and love.

She was also a practicing Justice of the Peace, a stalwart of the Levin Pottery Club and much-loved mother of Simon and Jeremy, and a grandmother of Ben, Toby, Anna, Charlotte, and Billy.
