Greetings!
There's a new stable Tor release today, 0.4.6.6. It changes very little since 0.4.6.5: the only significant change is that we merged the fix for the issue that was preventing builds with older versions of GCC.
As usual, you can find the release at https://dist.torproject.org/ .
If you are already shipping Tor 0.4.6.5, there is no reason to upgrade to 0.4.6.6. If you have had problems compiling 0.4.6.5, this release should fix them for you.
Here's the changelog:
Changes in version 0.4.6.6 - 2021-06-30 Tor 0.4.6.6 makes several small fixes on 0.4.6.5, including one that allows Tor to build correctly on older versions of GCC. You should upgrade to this version if you were having trouble building Tor 0.4.6.5; otherwise, there is probably no need.
o Minor bugfixes (compilation): - Fix a compilation error when trying to build Tor with a compiler that does not support const variables in static initializers. Fixes bug 40410; bugfix on 0.4.6.5. - Suppress a strict-prototype warning when building with some versions of NSS. Fixes bug 40409; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (testing): - Enable the deterministic RNG for unit tests that covers the address set bloomfilter-based API's. Fixes bug 40419; bugfix on 0.3.3.2-alpha.
Official announcement to follow after the website has updated.
Best wishes,
