August 2014 beta build was a really small update and the only one in year 2014. To be honest, my feeling also was that project has been abandoned. ST3 was silent for about a year and is supported by the single developer (as far as I understand it). No updates (except for one in August) in the times of Atom release, this looked like there was no more motivation for the Sublime Text developer. I am really happy that it's not true and Sublime is active again in 2015.
