timeline

I understand that there will be a 1.3.6 and 2.0, on separate development paths. I need to make one of my GL sites easy for my successor to upgrade, so want to avoid using PhpLinks/Forum plugins. Will there be proper categories in the 1.3.6 release? and will there be some form of threaded discussion forum? Also, what is a reasonable timescale for 1.3.6? Are we looking at a month, or six? A timescale would help me plan development of my site. Thanks for any input.

Cheers, Euan.
