I see that some plugins doesn't work as expected anymore.
So, this can be related to removed/changed functions in BBLog.
Important:
All technical changes will always be in the last DEV Version of BBLog before the live release so there is time (mostly 1-2 weeks) to check your plugin against new changes and fix problems if there be some.
There is always a topic where you can see when a new DEV version has released.
Here a list of technical things that have been changed in BBLog 4.0.0
* BBLog.alert() have been removed - BBLog natively don't need it anymore - Use BBLog.popup() instead.
* BBLog.prompt() have been removed - BBLog natively don't need it anymore - Use BBLog.popup() instead.
