The final tag should have a format similar to the old one: nuttx-9.0.0 (or nuttx-9.0.0-rc1 for an RC) The version.sh script needs the "-" to parse the tag.
It would seem that if we wanted to make an April 30 release, we should create the tarball now and ask for beta testers. Or do you have some other plan to qualify the release.
Can the nightly build be directed to build the releasse branch?
