latest RT patches for the latest 4.20.6 release

Hello,

I found linux-stable-rt-4.20.2.tar.gz but the latest official patches are for 4.19.15 (in the rt directory).

While I can run the diffs against the regular 4.20.2 tree I'm curious if there will be official patches released against that version, or better yet, against current 4.20.6 stable version?

thanks Michael Umansky
