New Release: Tor 0.3.4.6-rc

There's a new alpha release available for download. If you build Tor from source, you can download the source code for Tor 0.3.4.6-rc from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release by some time next month.

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

Tor 0.3.4.6-rc fixes several small compilation, portability, and correctness issues in previous versions of Tor. This version is a release candidate: if no serious bugs are found, we expect that the stable 0.3.4 release will be (almost) the same as this release.

Changes in version 0.3.4.6-rc - 2018-08-06

• Major bugfixes (event scheduler):
  • When we enable a periodic event, schedule it in the event loop rather than running it immediately. Previously, we would re-run periodic events immediately in the middle of (for example) changing our options, with unpredictable effects. Fixes bug 27003; bugfix on 0.3.4.1-alpha.
• Minor features (compilation):
  • When building Tor, prefer to use Python 3 over Python 2, and more recent (contemplated) versions over older ones. Closes ticket 26372.

• Minor features (geoip):
  • Update geoip and geoip6 to the July 3 2018 Maxmind GeoLite2 Country database. Closes ticket 26674.
• Minor features (Rust, portability):
  • Rust cross-compilation is now supported. Closes ticket 25895.
• Minor bugfixes (compilation):
  • Fix a compilation warning on some versions of GCC when building code that calls routerinfo_get_my_routerinfo() twice, assuming that the second call will succeed if the first one did. Fixes bug 26269; bugfix on 0.2.8.2-alpha.
• Minor bugfixes (controller):
  • Report the port correctly when a port is configured to bind to "auto". Fixes bug 26568; bugfix on 0.3.4.1-alpha.
  • Parse the "HSADDRESS=" parameter in HSPOST commands properly. Previously, it was misparsed and ignored. Fixes bug 26523; bugfix on 0.3.3.1-alpha. Patch by "akwizgran".
• Minor bugfixes (correctness, flow control):
  • Upon receiving a stream-level SENDME cell, verify that our window has not grown too large. Fixes bug 26214; bugfix on svn r54 (pre-0.0.1)
• Minor bugfixes (memory, correctness):
  • Fix a number of small memory leaks identified by coverity. Fixes bug 26467; bugfix on numerous Tor versions.
• Minor bugfixes (portability):
  • Avoid a compilation error in test_bwmgt.c on Solaris 10. Fixes bug 26994; bugfix on 0.3.4.1-alpha.
• Minor bugfixes (testing, compatibility):
  • When running the ntor_ref.py and hs_ntor_ref.py tests, make sure only to pass strings (rather than "bytes" objects) to the Python subprocess module. Python 3 on Windows seems to require this. Fixes bug 26535; bugfix on 0.2.5.5-alpha (for ntor_ref.py) and 0.3.1.1-alpha (for hs_ntor_ref.py).
