As of this date MWM 22.214.171.124.1 is the latest version.
MWM tends to rebuild every two months.
Another one SHOULD be out in the May 2010 time frame but we NEVER
guarantee that time frame. Its an educated guess...but a pretty reliable
It is every other month. MWM 126.96.36.199 was just released last week.
Though MWM 2.0 is technically released, there is no upgrade path yet - and it's not really released for implementation teams yet.
There will continue to be MWM 1.5.x releases, roughly every other month, for probably the rest of this year. I imagine Product will announce later this year updated release schedules, migration plans, etc concerning 2011 and beyond.
