Re: Start of the NuttX 9.0 release cycle

[Gregory Nutt]

I agree that we should not let trivial cosmetic things onto the release
branch.  We should only permit showstopping, critical bugfixes onto the
release branch.  It is probably a fair comment that we brought too much
unimportant stuff in and the confuses things.  Let's add that to the
TIL:  Only showstopping, critical bugfixes my come into the release
branch.  Once the release branch is cut, it is not changed for any
reason other than to correct user-exposure to bugs.
I don't know how unimportant are the things that got back-ported.
There are 10 commits back-ported in nuttx/.  3 of them deal with bugs
in macOS build.  3 are pure typos, 1 is a typo that broke the cxd56xx
build if certain files were chosen,  1 updated the TODO file (some
lines about a bug were outdated/incorrect), and last 2 were for tools
and release notes (both needed by the final release).

I don't know how important the macOS changes are, but most if not all of 
the others were certainly not show-stopping, critical bugs. The 
stability and clarity of the release would probably be more important.
