That specific Aug 2014 update was probably in response to the Spring 2014 bans which made the tool safer. I've seen some local friends still use and even recommend it, and is probably safe now.

Though by that time it doesn't have much market share, thus there were only few bans reported which it supposedly caused.

Though better alternatives these times are KCV (where you choose a fork to follow. forks are just versions done by different people who implement separate updates).

Or if your system cannot support .NET Framework 4 (WinXP, Linux, Mac), you can go for a lightweight Chrome Browser extension, KC3, maintained by me.
