Earlier this year ., i tried its beta drop v2 .... had issues with plugins ie downloadAll and google toolbar.,,,

today i installed it on my test machine... it is working like charm.,. no bugs yet...

look has been changed ie buttons images .. plugins also recognize new version .. and install / update themselved..

i felt that memory usage has been optimized... it uses less mem than its predecessor...

i heard that bookmark rating has been kool (like google page rank)... but i never tried any of those...

so in short... my say is ., ,go for it ., . it is nice release ., and worth 3years of developers work/effort
