Changes
Below are the major changes of the released versions and links to more detailed release notes.
Stable
Yesterday, we quietly released version 0.4.8.20 to allow relay operators some time to upgrade and help mitigate medium-severity remote crash issues that were reported a few days ago through the HackerOne platform.
We have reserved two TROVE entries for these issues: TROVE-2025-014 and TROVE-2025-015.
Once a sufficient number of relays have upgraded, we will make the tickets associated with these TROVE entries public in the near future.
In the meantime, if any relay operators experience crashes or unusually high memory usage, please report it to us via the Tor relays mailing list: tor-relays@lists.torproject.org.
As of this announcement, our 0.4.8.20 Debian package on https://deb.torproject.org is now available. And so, as always, please upgrade as soon as possible.
Thank you!
