You can speed up the release of sme 8 by testing sme8beta4 (and yum update to beta5). Report your findings.
You should ALWAYS check hardware compatibility with the base OS that sme uses.
Using sme8beta4/5 should be OK, as it is well developed, you really have no choice with that hardware.
I'm sure there are plans to release a final sme 8, but it has always been said there is no specific timeframe, it will be ready when it is ready. More testers and developers would help speed up the process.
It has also been said in the past that upgrades from beta to final release is not guaranteed or supported. It has been known to work OK in the past, but some users have also reported problems.
The only sure answer here, is to reinstall a fresh copy of sme 8 final, when it is released.
