There were more than 250 commits since 2.2.0-alpha, thus it was overdue to get rid of the alpha in the tag now.
With some more improvements in the last couple weeks, we switch directly to Release Candidate as the response from community is, that the master branch is stable.
There are only some minor changes in the line before the final 2.2.0 release.
Punctual with the release of 2.2.0-rc1 SourceForge’s file upload is down because they moved to a new datacenter this week. They work hard on it.
When the upload is available again, we will supply the new installer there.
Source code and a Windows installer is available on GitHub already: LibreCAD-Installer-2.2.0-rc1.exe
