+- Bug fixes and improvements
+
+# New background processor
+
+- MISP has been using CakeResque for its background jobs for the better part of a decade. Whilst it has served us well, the library has been stale for a long time and carries a (for us) unnecesary complexity and is generally the most difficult part of the application to debug
+- Luciano "@righel" Righetti has implemented a completely new, compatible background processing engine using Supervisord
+- Queue and execute jobs the same way as you are used to from before, monitor worker progress via the tools provided by supervisord in addition to MISP
+- No scheduling capabilities, these were an unnecesary overhead for us before as we relied on corn jobs as our prefered scheduling mechanism anyway
+- Expect more improvements to this library over the course of the next months, but feel free to switch to using it already now
+- Currently it is completely optional and the old background processor will still be supported for a while
+- Be aware that manual setup steps are required to get the new processor working, refer to [the upgrade guide](https://gist.github.com/righel/8ebc6c84341f2aea7d0bfa124e535ef8) on the procedure, if you decide to start using it already now
+
+# Various CLI changes
+
+- Jakub Onderka has been doing a fair bit of refactoring and improvement of the CLI libraries
+- additional administrative tools added to help monitor and manage your MISP instance (such as redis memory diagnostics, mysql table optimisation tool, etc)
+
+# Various improvements
+
+- The previous version introduced a new STIX library as a replacement for the old one. This change did end up causing some update issues for some installations, the built in updater is now aware of this change and should allow you to easily update via the UI/API updater, with the new STIX library working as intended
+- A long list of improvements, thanks to all contributors! For a detailed list of changes, head over to the [changelog](https://www.misp-project.org/Changelog.txt)
