InfluxDB 2.0.0 Beta 15 has been released, featuring several potentially breaking changes, including the removal of the `migrate` command from the `influxd` binary, restrictions on variable names in the UI to avoid conflicts with Flux reserved words, and enhancements such as improved CLI tooling, enhanced UI performance, and an upgraded Flux Query Engine. The release is not intended for production use and invites users to provide feedback through the InfluxDB Community Slack channel.
