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.

In our last article, published in RIPE's website, we described the work that happened in 2020 related to giving IPv6 support to the Tor network. Tor 0.4.5.1-alpha is the first release that includes all the work described in the RIPE article. Relays running 0.4.5.1-alpha are the first to report IPv6 bandwidth statistics.

There's a new release candidate available for download. If you build Tor from source, you can download the source code for 0.4.5.3-rc from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release in 3-4 days.
We're getting closer and closer to stable here, so I hope that people will try this one out and report any bugs they find.
Tor 0.4.5.3-rc is the first release candidate in its series. It fixes several bugs, including one that broke onion services on certain older ARM CPUs, and another that made v3 onion services less reliable.
Though we anticipate that we'll be doing a bit more clean-up between now and the stable release, we expect that our remaining changes will be fairly simple. There will be at least one more release candidate before 0.4.5.x is stable.
Changes in version 0.4.5.3-rc - 2021-01-12
- Major bugfixes (onion service v3):
- Stop requiring a live consensus for v3 clients and services, and allow a "reasonably live" consensus instead. This allows v3 onion services to work even if the authorities fail to generate a consensus for more than 2 hours in a row. Fixes bug 40237; bugfix on 0.3.5.1-alpha.
- Minor features (crypto):
- Fix undefined behavior on our Keccak library. The bug only appeared on platforms with 32-byte CPU cache lines (e.g. armv5tel) and would result in wrong digests. Fixes bug 40210; bugfix on 0.2.8.1-alpha. Thanks to Bernhard Übelacker, Arnd Bergmann and weasel for diagnosing this.
It's with deep sorrow that we share that our dear friend, colleague, and Tor core contributor Karsten Loesing passed away on the afternoon of Friday, December 18, 2020. No one is prepared for such an unimaginable loss. Our deepest sympathies go to Karsten's family at this moment, his wife and his children.
