shortly after releasing releasing qf-newtree beta 7, the quakeforge team has released quakeforge 0.3.0 which is available at their download page. The list of changes would be too long to list and contain a lot of uninteresting stuff (at least for most players). If you want to know what has changed check the Changelog or browse their news.
Unluckily QuakeForge, nor any other "new" quakeworld client supports a good cheat protection which is required by online leagues, but you can never know ;)
