A new upstream Toolbx release was made:
https://github.com/containers/toolbox/releases/tag/0.0.99.6

It will be good to ship this in RHEL 9 to give customers the latest fixes and improvements. It is already in Fedora Rawhide, and is going through Bodhi for Fedoras 39, 40 and 41.

If nothing major goes wrong, then I am planning to shrink wrap this release into a pretty dot-zero version number after two weeks or so. It should have almost zero changes to the code, and is mainly intended to break our current string of nine-nine releases with something that's easy for people to remember and talk about.
