Then what was so odd? You must be confused.
I had all the previews before beta 1, I then installed beta 1 over DP5, did not get the DP6 update, installed DP6 manually over beta 1, now i don't get beta 2 either.
So, I don't get updates for the DP's nor the beta's, so that's why I find it 'odd'.

Officially gb doesn't even exist.
Gb or GB.
