I had this exact same problem when I upgraded and it really freaked me out. All you need to type is: '/filter macros all'
(You might want to play around with the setting '/filter macros enhanced' , but '/filter macros all' should reset everything.
Yea, somehow in the readme/changelog it was not indicated that the default /filter setting was going to change with the new release :) (Or, at least it changed on mine! ..hehe)
