Source code for Tor 0.3.3.8 is now available; You can download the source code from the usual place on the website. Packages should be available within the next several weeks, with a new Tor Browser by some time in September. (Don't worry, this isn't an urgent release for clients.)

There's also a non-stable release (0.3.4.4-rc) coming out today: for that announcement, see the tor-talk mailing list.

Changes in version 0.3.3.8 - 2018-07-09 Tor 0.3.3.8 backports several changes from the 0.3.4.x series, including fixes for a memory leak affecting directory authorities.

o Major bugfixes (directory authority, backport from 0.3.4.3-alpha): - Stop leaking memory on directory authorities when planning to vote. This bug was crashing authorities by exhausting their memory. Fixes bug 26435; bugfix on 0.3.3.6.

o Major bugfixes (rust, testing, backport from 0.3.4.3-alpha): - Make sure that failing tests in Rust will actually cause the build to fail: previously, they were ignored. Fixes bug 26258; bugfix on 0.3.3.4-alpha.

o Minor features (compilation, backport from 0.3.4.4-rc): - When building Tor, prefer to use Python 3 over Python 2, and more recent (contemplated) versions over older ones. Closes ticket 26372.

o Minor features (geoip): - Update geoip and geoip6 to the July 3 2018 Maxmind GeoLite2 Country database. Closes ticket 26674.

o Minor features (relay, diagnostic, backport from 0.3.4.3-alpha): - Add several checks to detect whether Tor relays are uploading their descriptors without specifying why they regenerated them. Diagnostic for ticket 25686.

o Minor bugfixes (circuit path selection, backport from 0.3.4.1-alpha): - Don't count path selection failures as circuit build failures. This change should eliminate cases where Tor blames its guard or the network for situations like insufficient microdescriptors and/or overly restrictive torrc settings. Fixes bug 25705; bugfix on 0.3.3.1-alpha.

o Minor bugfixes (compilation, backport from 0.3.4.4-rc): - 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.

o Minor bugfixes (control port, backport from 0.3.4.4-rc): - Handle the HSADDRESS= argument to the HSPOST command properly. (Previously, this argument was misparsed and thus ignored.) Fixes bug 26523; bugfix on 0.3.3.1-alpha. Patch by "akwizgran".

o Minor bugfixes (memory, correctness, backport from 0.3.4.4-rc): - Fix a number of small memory leaks identified by coverity. Fixes bug 26467; bugfix on numerous Tor versions.

o Minor bugfixes (relay, backport from 0.3.4.3-alpha): - Relays now correctly block attempts to re-extend to the previous relay by Ed25519 identity. Previously they would warn in this case, but not actually reject the attempt. Fixes bug 26158; bugfix on 0.3.0.1-alpha.

o Minor bugfixes (restart-in-process, backport from 0.3.4.1-alpha): - When shutting down, Tor now clears all the flags in the control.c module. This should prevent a bug where authentication cookies are not generated on restart. Fixes bug 25512; bugfix on 0.3.3.1-alpha.

o Minor bugfixes (testing, compatibility, backport from 0.3.4.4-rc): - When running the hs_ntor_ref.py test, 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 0.3.1.1-alpha. - When running the ntor_ref.py test, 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.
