New release candidate: Tor 0.4.5.4-rc

There's a new release candidate available for download. If you build Tor from source, you can download the source code for 0.4.5.4-rc from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely around this coming Tuesday.

Tor 0.4.5.4-rc is the second release candidate in its series. It fixes several bugs present in previous releases.

We expect that the stable release will be the same, or almost the same, as this release candidate, unless serious bugs are found.

Changes in version 0.4.5.4-rc - 2021-01-22

Major bugfixes (authority, IPv6):
- Do not consider multiple relays in the same IPv6 /64 network to be sybils. Fixes bug 40243; bugfix on 0.4.5.1-alpha.
Major bugfixes (directory cache, performance, windows):
- Limit the number of items in the consensus diff cache to 64 on Windows. We hope this will mitigate an issue where Windows relay operators reported Tor using 100% CPU, while we investigate better solutions. Fixes bug 24857; bugfix on 0.3.1.1-alpha.
