Hi Derek,

as Xpand, Xtend and Check are technically one language (with just a
couple of different coarse-grained concepts and file extensions) they
are all part of M2T/Xpand.

Cheers,
Sven

Hi Sven,

I asked this over on oAW forum a while back, but I'm wondering if we
could consider eclipse versions of all of this close to production
ready. In other words, would it make sense for oAW consumers with
mature projects to begin migrating now?

thanks,

Miles

Hi Miles,

we don't state, that you can savely migrate now.
Officially you should wait till June.
There'll be some minor changes in TMF Xtext until June, which might
force people to change their projects accordingly.
Also Xpand is not yet migrated completely. It seems that we missed some
fixes from the oAW 4.3.1 stream, but we'll have the migration completed
for M7. Note that we of course already use Xpand, Xtend and Check in TMF
Xtext.
Moreover we find TMF Xtext to be much more solid and flexible and it
even now has more documentation.

So if you want to give it a try, be sure that we'll help you. :-)
