checklist = 2 | 3 | == Source release == 4 | 5 | - Check for uncommitted changes to master. 6 | - Update OPUS_LT_* API versioning in configure.ac. 7 | - Tag the release commit with 'git tag -s vN.M'. 8 | - Include release notes in the tag annotation. 9 | - Verify 'make distcheck' produces a tarball with 10 | the desired name. 11 | - Push tag to public repo. 12 | - Upload source package 'opus-${version}.tar.gz' 13 | - Add to https://svn.xiph.org/releases/opus/ 14 | - Update checksum files 15 | - svn commit 16 | - Copy to archive.mozilla.org/pub/opus/ 17 | - Update checksum files there as well. 18 | - Add release notes to https://git.xiph.org/opus-website.git 19 | - Update links and checksums on the downloads page. 20 | - Add a copy of the documentation to 21 | and update the links. 22 | - Update /topic in #opus IRC channel. 23 | 24 | Releases are commited to https://svn.xiph.org/releases/opus/ 25 | which propagates to downloads.xiph.org, and copied manually 26 | to https://archive.mozilla.org/pub/opus/ 27 | 28 | Website updates are committed to https://git.xiph.org/opus-website.git 29 | which propagates to https://opus-codec.org/ 30 | 31 | == Binary release == 32 | 33 | We usually build opus-tools binaries for MacOS and Windows. 34 | 35 | Binary releases are copied manually to 36 | https://archive.mozilla.org/pub/opus/win32/ 37 | 38 | For Mac, submit a pull request to homebrew. 39 | 40 | == Website updates == 41 | 42 | For major releases, recreate the files on https://opus-codec.org/examples/ 43 | with the next encoder. 44 |
