Hi, The breaking window for Superset 4.0 is over and no more breaking changes are accepted on master. We’re back to SemVer (https://semver.org/) constraints. We’ll generate 4.0 RC1 and begin the stabilization phase where we ask for help from the community to keep the focus on fixes and testing.
Thanks to everyone who contributed during the breaking window. If you missed it, don’t worry, 5.0 is not too far. You can check our release schedule at https://github.com/apache/superset/wiki/Release-Process#schedule. Best regards, Michael S. Molina
