How to release RawTherapee

1. Tea
2. Pull and update
3. Run:

   ./tools/generateTranslationDiffs

   Perform final language file updates.
4. Run:

   dos2unix rtdata/languages/* and rtdata/profiles/*

5. Once RELEASE_NOTES.txt, language files, profiles, a new splash screen, etc. are ready, commit to new branch:

   git checkout -b release-5.2 && git commit -a -m "Preparing for release 5.2-rc1"

6. Once others have revised the changes, merge this "release-5.2" branch into "releases":

   git checkout releases

   git pull

   git merge release-5.2

7. Tag:

   git tag -a "5.2-rc1" -m "Tagged RawTherapee 5.2-rc1"

   git push origin "5.2-rc1"

8. Make a source tarball and upload it to the website:

   ./tools/generateSourceTarball

   sha1sum rawtherapee-5.1-rc1.tar.xz > rawtherapee-5.1-rc1.tar.xz.sha1

9. When ready for a final release (5.2, not 5.2-rc3), do as above, merge "release-5.2" into "releases", tag and deleted "release-5.2". Never delete branch "releases".
