The AspectJ 5 M2 candidate build (see the aspectj-users list for more
info) is now available in the latest AJDT development build, version
188.8.131.5250325175227, available from: http://www.eclipse.org/ajdt/download.html with one version for Eclipse 3.0
and another for Eclipse 3.1M5a.
We'll put out an AJDT 1.2.0M3 release after AspectJ 5 M2 has been declared
"final". We're also close to another Eclipse 3.1 release (M6 is due 1
April), so we'll try to add support for that and release soon afterwards).
