Kolab 3 vs Kolab 4

Kolab has undergone a major revision from generation 3 to generation 4.

The following is a short list of major changes:

  • Kolab is now at its core a PHP application in laravel, which integrates all services via an API.
  • Historically, groupware data has been stored in XML messages in IMAP (so called Kolab Objects). This is no longer the case. Kolab now uses Cyrus provided DAV for Calendar/Tasks/Contacts and the Kolab Files API for files.
  • Packages are no longer the primary distribution mechanism with a switch to conatinerized deployments.
  • LDAP is no longer used by Kolab.
  • The Webadmin panel has been replaced by Kolab Cockpit.
  • pykolab/kolabd/wallace functionality has been integrated into the central Kolab API.
