The best version so far in my opinion, very stable loads of features great job.
From a web developers perspective my favourite features are the new re-factoring and CSS3 support.
For me NetBeans 7.1, EXTJS, PACKTAG and DWR are all you need to build good one page web apps.
Get NetBeans 7.1 here for a full set of features go here.
Still no usable Geronimo support though.
