LibreCAD as a whole is not polished enough for the project maintainer to feel comfortable making a major release just yet (but we’re pretty close). Within the project “major release” means a supported release that packagers from different distros can reference and at the moment the pace of development, feature implementation, menu swap-a-roo and bug squashing just doesn’t justify freezing a version number.
So its in “very high beta”. Regardless whether an “rc2” or “rc3” suffixes the release, its already very usable and the more folks who can easily get access to it the better our bug checking (and possibly manual) will be. To that end I have rolled v1.0.0rc2 x86 and AMD64 RPMs for Fedora 14, 15 and 16 as well as for EPEL 6 environments (I think it should work on EPEL 5-type systems, but I could be wrong) and am hosting them here. This is a temporary situation that will change once we do have a major release and LibreCAD gets incorporated into the mainstream Fedora and EPEL repositories.
Until then feedback, recommendations, etc. are of course welcome. If you’re interested in getting involved this bounce page will help you find anything you might be looking for.
