Subject Re: [math] release plan for 3.0 ?
Date Wed, 23 Nov 2011 13:41:08 GMT
As a [math] outsider and curious watcher of the [math] "sub-ML" I can offer
the XP mantra: release early, release often. It will never be perfect ;)
Take care of API breaking changes, release 3, tweak features for 3.1 and so
on.

2c,
Gary
