Following the 1.2.0beta1 release two weeks ago, a final 1.2.0 release of theora was wrapped up today. This new release is tagged in the Xiph gitlab theora instance and you can fetch it from the Theora home page as soon as someone with access find time to update the web pages. In the mean time (automatically removed after 14 days) the release tarball is also available as a git build artifact from CI build of the release tag.

The list of changes since The 1.2.0beta release from the CHANGES file in the tarball look like this:

libtheora 1.2.0 (2025 March 29)

• Bumped minor SONAME versions as oc_comment_unpack() implementation changed.
• Added example wrapper script encoder_example_ffmpeg (#1601 #2336).
• Improve comment handling on platforms where malloc(0) return NULL (#2304).
• Added pragma in example code to quiet clang op precedenca warnings.
• Adjusted encoder_example help text.
• Adjusted README, CHANGES, pkg-config and spec files to better reflect current release (#2331 #2328).
• Corrected english typos in source and build system.
• Switched http links to https in doc and comments where relevant. Did not touch RFC drafts.

When I a few days ago discovered that a security problem reported against the theora library last year was still not fixed, and because I was already up to speed on Xiph development, I decided it was time to wrap up a new theora release. This new release was tagged in the Xiph gitlab theora instance Saturday. You can fetch the new release from the Theora home page.

The list of changes since The 1.2.0alpha1 release from the CHANGES file in the tarball look like this:
