Re: [m2m-atl-dev] Feature proposal: ATL research VM with built-in composition support

Hello Andreza,

The new VM should be available in CVS shortly after approval (+- 1 week?).
Release will take longer, as this must be done together with the main ATL
releases. The PMC_Approved flag has been set by now, so the code is one step
further in the IP process. I'm not sure what other steps are necessary, and
how long the entire approval process will take, though.

If you really want to try out the code already, you can take a look at:
http://soft.vub.ac.be/soft/research/mdd/emftvm
N.B. The Eclipse committed code will *not* be compatible with the above
version of EMFTVM due to rebranding (package names, plug-in IDs, etc.), and
the above version will be discontinued as soon as EMFTVM is part of ATL.

Regards,
Dennis
