Wicketstuff versions

[Charles Deal]

I'm a little confused about the versioning for Wicketstuff.  I am currently
using inmethod-grid, jquery, and yui.  All three projects now have a
1.4-SNAPSHOT and a 1.4.2-SNAPSHOT version and (inmethod-grid and yui both
have a 1.4.1 release version).  What is the difference between the two
SNAPSHOT versions?  I tried searching on it and looking at the Wicketstuff
Wiki, but could not find an explanation.  Which should we be using?
