Hi @pjankauskas
Welcome back to the community!
It is good that you ask because it’s generally the recommended practice to be aware of the release notes before upgrading. In every release, there are release notes which provide all the necessary details about changes as well as if there’s anything that the user needs to change.
For version 2.42, please check out this post: DHIS2 version 42 and Android Capture 3.2 are now available!
Thanks!
