There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.3.4-rc from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely later this week.
This is a release candidate: unless we find new significant bugs in it, the stable release for the 0.4.3.x series will be substantially the same as this release.
Tor 0.4.3.4-rc is the first release candidate in its series. It fixes several bugs from earlier versions, including one affecting DoS defenses on bridges using pluggable transports.
There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.3.3-alpha from the download page on the website. Packages should be available over the coming days, including a new alpha Tor Browser.
Remember, this is an alpha release: you should only run this if you'd like to find and report more bugs than usual.
Tor 0.4.3.3-alpha fixes several bugs in previous releases, including TROVE-2020-002, a major denial-of-service vulnerability that affected all released Tor instances since 0.2.1.5-alpha. Using this vulnerability, an attacker could cause Tor instances to consume a huge amount of CPU, disrupting their operations for several seconds or minutes. This attack could be launched by anybody against a relay, or by a directory cache against any client that had connected to it. The attacker could launch this attack as much as they wanted, thereby disrupting service or creating patterns that could aid in traffic analysis. This issue was found by OSS-Fuzz, and is also tracked as CVE-2020-10592.
We do not have reason to believe that this attack is currently being exploited in the wild, but nonetheless we advise everyone to upgrade as soon as packages are available.
There are also new stable releases coming out today; I'll describe them in an upcoming post.
We have new releases today. If you build Tor from source, you can download the source code for 0.4.2.7 from the download page on the website. Packages should be available within the next several days, including a new Tor Browser.
There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.3.2-alpha from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely in the coming week.
Remember, this is an alpha release: you should only run this if you'd like to find and report more bugs than usual.
This is the second stable alpha release in the Tor 0.4.3.x series. It fixes several bugs present in the previous alpha release. Anybody running the previous alpha should upgrade and look for bugs in this one instead.
We have two new stable releases today. If you build Tor from source, you can download the source code for 0.4.2.6 from the download page on our website. Packages should be available within the next several weeks, with a new Tor Browser by mid-February.
This is the first alpha release in the 0.4.3.x series. It includes improved support for application integration of onion services, support for building in a client-only mode, and newly improved internal documentation (online at https://src-ref.docs.torproject.org/tor/). It also has numerous other small bugfixes and features, as well as improvements to our code's internal organization that should help us write better code in the future.
Ater months of work, we have a new stable release series! If you build Tor from source, you can download the source code for 0.4.2.5 on the website. Packages should be available within the next several weeks, with a new Tor Browser around January 7.
I'd like to tell you about some of our work your contributions can help over the coming year. I'll be focusing on things that my team works on in the "tor" program itself.

Remember, this is a release candidate: there may still be more bugs here than usual. We'd love to know about any new ones, so that we can try to get them fixed before we call this series stable.
Tor 0.4.2.4-rc is the first release candidate in its series. It fixes several bugs from earlier versions, including a few that would result in stack traces or incorrect behavior.
