+Changes in version 0.3.3.5-rc - 2018-04-15
+ Tor 0.3.3.5-rc fixes various bugs in earlier versions of Tor,
+ including some that could affect reliability or correctness.
- - Directory authorities no longer vote in favor of the Guard flag for
- relays that don't advertise directory support. Starting in Tor
- 0.3.0.1-alpha, Tor clients have been avoiding using such relays in the
- Guard position, leading to increasingly broken load balancing for the
- 5%-or-so of Guards that don't advertise directory support. Fixes bug
- 22310; bugfix on 0.3.0.6.
+ This is the first release candidate in the 0.3.3 series. If we find no
+ new bugs or regression here, then the first stable 0.3.3 release will
+ be nearly identical to this one.
- o Major bugfixes (protover, voting):
+ o Major bugfixes (security, protover, voting):
- Revise Rust implementation of protover to use a more memory-
efficient voting algorithm and corresponding data structures, thus
- avoiding a potential (but small impact) DoS attack where specially
- crafted protocol strings would expand to several potential
- megabytes in memory. In the process, several portions of code were
- revised to be methods on new, custom types, rather than functions
- taking interchangeable types, thus increasing type safety of the
- module. Custom error types and handling were added as well, in
- order to facilitate better error dismissal/handling in outside
- crates and avoid mistakenly passing an internal error string to C
- over the FFI boundary. Many tests were added, and some previous
- differences between the C and Rust implementations have been
- remedied. Fixes bug 24031; bugfix on 0.3.3.1-alpha.

o Minor features (config options):
- Change the way the default value for MaxMemInQueues is calculated.
- We now use 0.4 * RAM if the system have 8 GB RAM or more, otherwise
- we use the former value of 0.75 * RAM. Closes ticket 24782.
+ We now use 40% of the hardware RAM if the system has 8 GB RAM or

o Minor features (geoip):
- Update geoip and geoip6 to the April 3 2018 Maxmind GeoLite2
Country database. Closes ticket 25718.
- o Minor bugfix (Exit node DNS retries):
- - Re-attempt timed-out DNS queries 3 times before failure, since our
- timeout is 5 seconds for them, but clients wait 10-15. Also allow
- slightly more timeouts per resolver before giving up on it in the
- case where an exit has multiple resolvers configured. Fixes bug
- 21394; bugfix on 0.3.1.9.

o Minor bugfixes (client):
- When using a listed relay as a bridge, and also using
microdescriptors, and considering that relay as a non-bridge in a
- circuit, consider its microdescriptor as a valid source of
- information about that relay. Fixes bug 25691; bugfix

- o Minor bugfixes (configuration):

o Minor bugfixes (controller):
- Restore the correct operation of the RESOLVE command, which had
been broken since we added the ability to enable/disable DNS on
specific listener ports. Fixes bug 25617; bugfix on 0.2.9.3-alpha.
