If you can wait then no, 10.x.0 are the "releases".  If you are using
pre-built binaries from some Linux distribution or other distributor
then the distributor usually picks up the current branch head for you.

Well, all of GCC 10.x.[01] are one major release with a major release
cadence of about one year.  Everything else inbetween is just accumulated
bugfixes with the "conveniece" of us doing 10.2.0 and later 10.3.0 at
random points to officially release a tarball with accumulated bugfixes.

You could say we should make it GCC 10.bugfix-nr and thus only have
two numbers ;)
