mainly fixing the ultralisk splash bug, but i bet they did some things more, the patch was around 25mbyte big or so.
edit:
* Fixed an issue where Ultralisk cleave range was being unintentionally extended by larger targets.
* Fixed an issue where the Phoenix's Graviton Beam was automatically canceled if you used it just after the Phoenix reached 50 energy.
* Fixed an issue where queuing Return Cargo on a worker would cause it to ignore the built-in delay after it finished gathering.
* Fixed an issue where players watching older replays or saved games would experience stuttering.
* Fixed an issue where some Mac users were unable to join games properly.
