This is a checklist of the steps to do a stable release. Some of this can be automated in the future.

Branching[edit]

Make sure all release blocker bugs are resolved
Make sure whatsnew.txt is up to date
branch wip -> rel/codename
Put the release codename into codename.txt on the branch, also update the svn revision where the branch happened
Run docs/update-html.sh after updating codename.txt, so it updates the codename in the .xml. (Note that none of the distrib or release scripts do this automatically.)
Update any of the README-* files which reference release codename at the top

Release Building[edit]

On each build environment, run the release scripts in the rel/codename branch in the release folder. (make sure the repo is fully updated)
Run release-linux-x86.sh on a 32 bit Linux build env
Run release-linux-x86_64.sh on a 64 bit Linux build env
Run release-mac.sh on a Mac build env
Run release-win.bat on a Windows build env
Run release-android.sh on a Linux Android build env

Files will be available from https://hamsterrepublic.com/ohrrpgce/archive/
Ask the denizens of SlimeSalad forums and Discord to test
Download and test for each platform
To sanity-check the "Distribute Game" menu, you can ssh into motherhamster.org (HamsterRepublic.com) and run script/ohrstable.sh -p to update the stable links just for the player-only files.
- Note that if this release increments the packaging_version in buildinfo.ini as compared to the previous release, then this test may break the "Distribute Game" feature of previous stable versions, and should only be done briefly, with caution

Some of the above steps may need to be repeated if problems are found in the testing phase
To finalize the release, ssh into motherhamster.org (HamsterRepublic.com) and run script/ohrstable.sh to update all the links.
Run the release/release-docs.sh script from the rel/codename branch on a Linux dev env
Run the release/release-itchio.sh script from any branch on a Linux computer

Update the links on the Downloads page
Update the page that describes the release to say it is current.
Modify previous release page to mention that it's obsolete
Update Current version to redirect to the new release's page
Update any other relevant pages in Category:Articles that change at each release
Remove the {{WIP}} tag for any pages that mention WIP features when appropriate.
Mention the update on the News page

Add a "rel:..." label for the new release
Replace the rel: nightlies label on any open bugs with the new rel label (some of these bugs may actually have been present in the previous release, but that's OK)
Add a milestone for the next release
