Timestretch and continue working, great!

Did this feature arrive in C9 or is it new in C9.5?

I can set up a mass of files to timestretch, pitch shift etc. and instead of locking me out while it chews it all over, I can carry on working! I’ve not seen this mentioned in the promotion, but it’'s a useful time-saver.

EDIT: Aah, I understand this is Direct Offline Processing! I used to go shopping while the computer worked through a big set of files!
