Sage 3.0.2.rc0 released

Hello folks,

this is 3.0.2.rc0, the likely final release of the 3.0.2 series and hopefully next to identical to the final 3.0.2. What is new?

• Franco Saliola and Peter Jipsen's posets and semi-lattive patch
• Robert Miller's self-orthogonal binary codes
• Bjarke Hammersholt Roune's Frobby is now an optional spkg
• Pbuild should now pass the doctests since #3097 has been fixed

In addition there were the usual bug fixes. Please build and doctest as usual and report any issues you see.

Sources and a sage.math-only binary in the usual places:

• Sage 3.0.2 sources
  
• Sage 3.0.2 sage.math-only binary
  

Cheers,

Michael
