Great @David_Muturi1 to see you in the community! Thank you for being a proud member.
As you can see in the patch release note announcement, you can find all the links (which are on Github):
There’s also the upgrade notes in the list. dhis2-releases/releases/2.39/README.md at master · dhis2/dhis2-releases · GitHub
You can always find them in the community site under the tag patch-releases or release .
They are available on the site as well, DHIS 2.39 Overview - DHIS2 so I hope you have more than one option to access.
I hope this helps. Thanks!
