We released a new version of the Wave Preview server yesterday, and
there was one resolved issue from the issue tracker:
Issue 591: Bug: Robot unable to resize Image object
Those changes are also documented in the changelog:
http://code.google.com/p/google-wave-resources/wiki/WaveAPIsChangeLog
If you find a regression bug, please report it in the issue tracker if
others confirm your suspicions.
Note: There is a known regression bug with event.getButtonName(). This
should be fixed in next release.
