Continuum on current fast ring build

[Sammibulin]

So I haven't been following the fast ring change logs as of late because I have found this update so far to be not very interesting for mobile. Especially when compared to the anniversary update for mobile. My question is, I know that Windowed Apps and continuum improvements are planned for this update, but have they been implemented yet? I haven't seen any info or videos on these improvements other than a MSFT display video put out a while ago.
