There has been some progress with the latest multiple scala version
support recently, and it just hit the latest nightly ! We'd love a bit
of help hashing out the kinks and details !
If you're interested in testing it out on your 2.10 projects, here's a
blog post describing the latest changes, and how you can help :

The latest nightly is available here:
http://download.scala-ide.org/nightly-scala-ide-4.0.x-211x
We would be tremendously grateful if developers were to try it out,
open a couple of 2.10 projects, and report what works for them and
what doesn't. We already have further improvements that are going to
build on top of this for the next milestone, but we'd love to hear
from you in the meantime.
