Yeah, I questioned that in the IRC channel and some of the others were confused about that. I can only hope Wayne just messed up the order of some of the items.
KiCad really needs a release soon. There are so many huge features that have only received testing by people using nightlies.
In the IRC Wayne said that he had been hoping for a pre-release for FOSDEM, but has slipped. Full turn off of Legacy would leave too many holes, unless his build is far ahead of Nightly.
I am all for continuing deprecation of Legacy, but right now I still have to switch to it frequently due to a few things missing
Time to do some testing, looking at the Nightly build size two big steps in file size happened on the 16th and the 19th this month, so something significant has been added
