Ofc I won't update while its in beta, just asking for people's experience with 4.1 generally , did anyone test it thoroughly, is there really some performance and overall boost ? I had 4.0 on live site, was good first week, after that performance hit from time to time was awful, plus lot of small bugs, posting youtube links was really buggy. And there isn't much themes for 4.x as well, skiners are telling coding in 4.x is a mess. Doing little research for skins,mods etc for guild website , not yet sure to concentrate on 3.4 or 4.x. Maybe 4.x is flashy but atm 3.4 looks safer and more stable.
