FME 2013 was released Jan 15 with Build 13261
Now I find Build 13264 in the download area and FME Pedia has the info that FME 2013 is Build 13264. see: http://fmepedia.safe.com/articles/FAQ/Build-Numbers-for-FME-Versions
I couldn't find any info about the difference between 13261 and 13264 ?!
We want to build on top of official FME 2013. This confusion is unexpected and not really helpful.
