This release backports important security fixes from Firefox 115.3.1. There were no Android-specific security backports from Firefox 115.3.0.
This is our sixth alpha release in the 13.0 series which represents a transition from Firefox 102-esr to Firefox 115-esr. It is also our first release-candidate build for 13.0 stable. If you find any issues, please report them on our gitlab or on the Tor Project forum.
We have completed our annual esr transition audit, and the final reports should be available in our tor-browser-spec repository in the audits directory. All of the interesting upstream patches have either been disabled or found to not be a problem for us on closer inspection.
Build Output Naming Updates
As a reminder from the 13.0a3 release post, we have made the naming scheme for all of our build outputs mutually consistent. If you are a downstream packager or in some other way download Tor Browser artifacts in scripts or automation, you will have a bit more work to do beyond bumping the version number once the 13.0 alpha stabilizes. All of our current build outputs can be found in the distribution directory
