Tor Browser 13.0.11 is now available from the Tor Browser download page and also from our distribution directory.

This is an emergency release which updates our the domain fronting configuration for the Snowflake pluggable transport and the moat connection to the rdsys backend used by the censorship circumvention system.

A known issue is that the source archives do not match likely due to a change in xz-utils (the underlying source in the archive is identical, only the compressed archive differs). This is not considered a blocker for this release and is being tracked here:

• https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/41102
