[jQuery] bug in click() after upgrade to svn $Rev: 670 $ from $Rev: 415 $

[jQuery] bug in click() after upgrade to svn $Rev: 670 $ from $Rev: 415 $

I use click() on an <a> and inside the callback I return false, to not execute the <a>.
when I upgraded to the latest svn version... it seems not to be returning my false, the <a> is invoked and I leave my page.
I switched back (to prove my sanity) and it worked again.
Is this bug known?
