HarfBuzz release walk-through checklist:

1. Open gitk and review changes since last release.

   • git diff $(git describe | sed 's/-.*//').. src/*.h prints all public API changes.

     Document them in NEWS. All API and API semantic changes should be clearly marked as API additions, API changes, or API deletions. Document deprecations. Ensure all new API / deprecations are in listed correctly in docs/harfbuzz-sections.txt

     If there's a backward-incompatible API change (including deletions for API used anywhere), that's a release blocker. Do NOT release.

2. Based on severity of changes, decide whether it's a minor or micro release number bump,

3. Search for REPLACEME on the repository and replace it with the chosen version for the release.

4. Make sure you have correct date and new version at the top of NEWS file,

5. Bump version in configure.ac line 3,

6. Do "make distcheck", if it passes, you get a tarball. Otherwise, fix things and commit them separately before making release, Note: Check src/hb-version.h and make sure the new version number is there. Sometimes, it does not get updated. If that's the case, "touch configure.ac" and rebuild. TODO: debug.

7. "make release-files". Enter your GPG password. This creates a sha256 hash and signs it.

8. Now that you have release files, commit NEWS, configure.ac, and src/hb-version.h, as well as any REPLACEME changes you made. The commit message is simply the release number. Eg. "1.4.7"

9. Tag the release and sign it: Eg. "git tag -s 1.4.7 -m 1.4.7". Enter your GPG password again.

10. Build win32 bundle.

a. Put contents of this on your ~/.local/i686-w64-mingw32,

b. Run ../mingw32.sh --with-uniscribe script to configure harfbuzz with mingw in a subdirector (eg. winbuild/),

c. make

d. Back in the parent directory, run ./UPDATE.sh(available below) to build win32 bundle.

11. Copy all artefacts to users.freedesktop.org and move them into /srv/www.freedesktop.org/www/software/harfbuzz/release There should be four files. Eg.:

-rw-r--r--  1 behdad eng 1592693 Jul 18 11:25 harfbuzz-1.4.7.tar.bz2
-rw-r--r--  1 behdad eng      89 Jul 18 11:34 harfbuzz-1.4.7.tar.bz2.sha256
-rw-r--r--  1 behdad eng     339 Jul 18 11:34 harfbuzz-1.4.7.tar.bz2.sha256.asc
-rw-r--r--  1 behdad eng 2895619 Jul 18 11:34 harfbuzz-1.4.7-win32.zip

12. While doing that, quickly double-check the size of the .tar.bz2 and .zip files against their previous releases to make sure nothing bad happened. They should be in the ballpark, perhaps slightly larger. Sometimes they do shrink, that's not by itself a stopper.

13. Push the commit and tag out: "git push --follow-tags". Make sure it's pushed both to freedesktop repo and github.

14. Go to GitHub release page here, edit the tag, upload artefacts and NEWS entry and save.
