New release candidate: Tor 0.4.6.4-rc

There's a new release candidate available for download. If you build Tor from source, you can download the source code for 0.4.6.4-rc from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely next week.

Remember, this is a not a stable release yet: but we still hope that people will try it out and look for bugs before the official stable release comes out in June.

Tor 0.4.6.4-rc fixes a few bugs from previous releases. This, we hope, the final release candidate in its series: unless major new issues are found, the next release will be stable.

Changes in version 0.4.6.4-rc - 2021-05-28

Minor features (compatibility):
- Remove an assertion function related to TLS renegotiation. It was used nowhere outside the unit tests, and it was breaking compilation with recent alpha releases of OpenSSL 3.0.0. Closes ticket 40399.
Minor bugfixes (consensus handling):
- Avoid a set of bugs that could be caused by inconsistently preferring an out-of-date consensus stored in a stale directory cache over a more recent one stored on disk as the latest consensus. Fixes bug 40375; bugfix on 0.3.1.1-alpha.
