I'm happy to announce the RC3 release of the upcoming 3.0.1 point release
It fixes a GridField regression introduced in 3.0.1-rc2.
3.0.1 should be a drop in upgrade for 3.0.0, fixing issues that either weren't critical enough to hold off the release of 3.0.0, or have been discovered in testing since 3.0.0 was released. Assuming no blocking issues are found, this RC release will become the final 3.0.1 release soon.
We request anyone developing a site on 3.0.0 upgrade now, to ensure there are no blocker issues with upgrading that would affect the 3.0.1 release.
