In software testing terminology Alpha testing is done by the client in the presence of the tester or developers and the test environment is not open for the end user...
Cosmetics come last.....Beta version software is likely to be useful for internal demonstrations and previews to select customers, but unstable and not yet ready for release.
Why are you testing Alpha and Beta releases on your users....
First it was 4.20, now Woof....
I would never spring a non final release upon an unsuspecting newbie...
I give them the tried and true...(Currently, for me, 4.12 and 3.01)
Better first impression, hmmm.."Looks cool" or "Rock solid"...
It only takes a minute to show them how easy it is to "customize" the looks....
I go with "Stable"....
But thats me....
