Can anyone in the BC Beta confirm whether ChangeActionBarPage (for AddOns like ReactionBar) and CancelPlayerBuff (for AddOns like ezDismount) are still able to be called while in combat from scripts or macros?

Rejoice ye! They do indeed work!

I went and kicked some snow in the face of a Winter Wolf, then attempted these two lines:

/changeactionbar 5
/script CancelPlayerBuff( 0 )

The observed results:

* my bar rolled over to set # 5
* Aspect of the Hawk was dismissed

Uhmm... that you can use them in macros does not mean you can use them in scripts ;)
They are buffing the macro interface so many mods won't be needed anymore :9
