Changes 2.7.3:
* Lots of little incremental bug fixes and enhancements in this release.
* Finally got some fixes out there for you Yahoo users behind some
  particularly annoying firewalls and proxies, among other fixes.  Enjoy!

Changes 2.7.2:
* We discovered a security issue in Pidgin 2.7.0 and 2.7.1 and decided to
  release a patched version quickly.  This release contains the fix for that
  crash, and a few other minor fixes.
