I'm sorry for being a moron, but I cannot figure out which of these is the most recent release of the 1.5 branch: 1.5/ 20-Nov-2012 15:48 - 1.5a1/ 20-Nov-2012 15:52 - 1.5a2/ 20-Nov-2012 15:52 - 1.5b1/ 20-Nov-2012 15:54 - 1.5b2/ 20-Nov-2012 15:54 - 1.5rc1/ 23-Nov-2012 08:36 - 1.5rc2/ 20-Nov-2012 15:56 - 1.5rc3/ 20-Nov-2012 15:57 I had hoped to use the time-stamp but that doesn't seem to help so much. Is a=alpha, b=beta, rc=release candidate and therefore "1.5" is the latest? And if there was a p=patch, that would be newer than "1.5"? Again, I know this is a dumb question. Thanks for your tolerance.
