  Tor 0.2.5.4-alpha includes several security and performance

  improvements for clients and relays, including blacklisting authority

  signing keys that were used while susceptible to the OpenSSL

  "heartbleed" bug, fixing two expensive functions on busy relays,

  improved TLS ciphersuite preference lists, support run-time hardening

  on compilers that support AddressSanitizer, and more work on the Linux

  sandbox code.

  There are also several usability fixes for clients (especially clients

  that use bridges), two new TransPort protocols supported (one on

  OpenBSD, one on FreeBSD), and various other bugfixes.

  This release marks end-of-line for Tor 0.2.2.x; those Tor versions

  have accumulated many known flaws; everyone should upgrade.
