Changes in version 0.2.3.8-alpha - 2011-11-??

  o Major bugfixes:

    - Correctly sanity-check that we don't underflow on a memory

      allocation (and then assert) for hidden service introduction

      point decryption. Bug discovered by Dan Rosenberg. Fixes bug 4410;

      bugfix on 0.2.1.5-alpha.

    - Fix a rare assertion failure when checking whether a v0 hidden

      service descriptor has any usable introduction points left, and

      we don't have enough information to build a circuit to the first

      intro point named in the descriptor. The HS client code in

      0.2.3.x no longer uses v0 HS descriptors, but this assertion can

      trigger on (and crash) v0 HS authorities. Fixes bug 4411.

      Bugfix on 0.2.3.1-alpha; diagnosed by frosty_un.

    - Don't crash when we, as the bridge authority, are asked for our own

      descriptor. Bugfix on 0.2.3.7-alpha, reported by Lucky Green.

  o Minor bugfixes:

    - Fix a memory leak when we check whether a hidden service

      descriptor has any usable introduction points left. Fixes bug

      4424. Bugfix on 0.2.2.25-alpha.

    - Fix a memory leak in launch_direct_bridge_descriptor_fetch() that

      occurred when a client tried to fetch a descriptor for a bridge

      in ExcludeNodes. Fixes #4383; bugfix on 0.2.2.25-alpha.

  o Packaging changes:

    - Make it easier to automate expert package builds on Windows

      by removing an absolute path from makensis.exe command.

  o Code simplifications and refactoring:

    - Remove some redundant #include directives throughout the code.

      Patch from Andrea Gelmini.
