Excellent work, thanks guys 
Window links are not working.
Hi, just a quick question. Will be possible, in the future, to import, or create on the fly, meshes with more than 64k verts?
This could be usefull in a lot of situations.
In Unity 5.0.0b19 the problem with rectangular DDS textures has been fixed. Good work!!

Is this release based on 4.6.1 changes?
The Windows Editor and WebPlayer links are giving out an 404 Error.

Says my beta 5 trial key expired?
Do current Pro 4.x Users still have access to the beta?
Did we ever?
It was my understanding that only Unity 5 Pro pre-orderers had access to the beta.
I just re-read the download page and it says that you’ll have a 5.x key on your keys page if you have access, and that key is necessary to use the beta.
If I choose a culling mask for the directional light it still is effecting the the geometry that is on a different layer. Someone have this issue too? It’s a directional light with no shadow.
I’ve prepared a whole collection of bug-reports but did not send yet) Some bugs is less, thanks! But unfortunately left many …
Sorry, my cut’n’paste of some component links were broken. Thanks for noting it. Should be fixed now.
No. The 4.6 merge happened shortly after our internal cut-off. It should catch up with b20.
