Read the disclaimer at the top of post#1.
Every build is a beta as they are based on the nightlies.
These builds are at the bleeding edge of development and nobody is forcing you to update everyday. If there is something in a new build that you can't live with then go back to your previous build or wait and read what others are finding before you update.
For me the last build is the best to date. The only problem for me was one SOD.
I don't see the "so many issues" you are complaining about.
Well I am still on 5/29, but myself and others have really bad lags and lots of FC/wait messages on the most recent builds, plus the SODs.
I realize they are all beta, thats why I put "stable" in quotes, sometimes the nightly builds bring cyanogenmod updates but more problems. I have seen some other builds (maybe in the NAND section) that do the beta and stable release thing.
