Re: [Emc-users] gmoccapy versions?

Yay! This is a good decision. Just a stepping stone to 2.7. (which won't be as long as 2.6 was) I have seen all the sausage making - with the relatively few people actively working on linuxcnc - big features/improvements are in the works. (and this takes time) (but thing are coalescing..)
