I don't normally bother announcing changes to my DiffEqs packages, but a couple of significant things cause me to ask everyone who has these packages to download the new version. Both issues relate to the extension of DSolve and NDSolve to accept input in matrix-vector form. First, I've changed the code so that these extensions are only applied if $VersionNumber < 5.0, since in version 5.0, the extensions aren't needed. Second, I had apparently extended DSolve a bit *too* far, since it was giving wrong answers!
