Tor 0.3.5.5-alpha includes numerous bugfixes on earlier releases, including several that we hope to backport to older release series in the future.

There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.3.5.4-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release by mid-December.

Remember, this is an alpha release: you should only run this if you'd like to find and report more bugs than usual.

Tor 0.3.5.4-alpha includes numerous bugfixes on earlier versions and improves our continuous integration support. It continues our attempts to stabilize this alpha branch and build it into a foundation for an acceptable long-term-support release.

Changes in version 0.3.5.4-alpha - 2018-11-08

• Major bugfixes (compilation, rust):
  • Rust tests can now build and run successfully with the --enable-fragile-hardening option enabled. Doing this currently requires the rust beta channel; it will be possible with stable rust once Rust version 1.31 is released. Patch from Alex Crichton. Fixes bugs 27272, 27273, and 27274. Bugfix on 0.3.1.1-alpha.
• Major bugfixes (embedding, main loop):
  • When DisableNetwork becomes set, actually disable periodic events that are already enabled. (Previously, we would refrain from enabling new ones, but we would leave the old ones turned on.) Fixes bug 28348; bugfix on 0.3.4.1-alpha.

There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.3.5.3-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely in the next few weeks.

Tor 0.3.5.2-alpha fixes several bugs in 0.3.5.1-alpha, including one that made Tor think it had run out of sockets. Anybody running a relay or an onion service on 0.3.5.1-alpha should upgrade.

There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.3.5.1-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release some time this week.

Tor 0.3.5.1-alpha is the first release of the 0.3.5.x series. It adds client authorization for modern (v3) onion services, improves bootstrap reporting, begins reorganizing Tor's codebase, adds optional support for NSS in place of OpenSSL, and much more.

Changes in version 0.3.5.1-alpha - 2018-09-18

• Major features (onion services, UI change):
  • For a newly created onion service, the default version is now 3. Tor still supports existing version 2 services, but the operator now needs to set "HiddenServiceVersion 2" in order to create a new version 2 service. For existing services, Tor now learns the version by reading the key file. Closes ticket 27215.
• Major features (relay, UI change):
  • Relays no longer run as exits by default. If the "ExitRelay" option is auto (or unset), and no exit policy is specified with ExitPolicy or ReducedExitPolicy, we now treat ExitRelay as 0. Previously in this case, we allowed exit traffic and logged a warning message. Closes ticket 21530. Patch by Neel Chauhan.
  • Tor now validates that the ContactInfo config option is valid UTF- 8 when parsing torrc. Closes ticket 27428.

Changes in version 0.3.4.2-alpha - 2018-06-12

• Directory authority changes:
  • Add an IPv6 address for the "dannenberg" directory authority. Closes ticket 26343.
• Major bugfixes (security, directory authority, denial-of-service, also in 0.3.3.6):
  • Fix a bug that could have allowed an attacker to force a directory authority to use up all its RAM by passing it a maliciously crafted protocol versions string. Fixes bug 25517; bugfix on 0.2.9.4-alpha. This issue is also tracked as TROVE-2018-005.
