What is ending

The opposite page to the preview radar. Runtimes losing support, models being retired, APIs going away, and behaviour changes with a date attached — on one countdown, nearest first.

    The Supervisor API API Agents

    The Beta API for supervisor agents reaches end of life and stops being available.

    Move to a custom agent deployed on Databricks Apps, which is the documented path.

Dates come from the Databricks documentation and are re-checked by the agent. A runtime version is supported for roughly six months, and a long-term support version for three years from its general availability. Model retirements get at least three months of notice after the deprecation is announced.

Newsletter

Know before the date, not after

End-of-support dates are announced months ahead and then forgotten. Tick “Deprecations and end of support” and the ones that touch what you use arrive in your inbox while there is still time to move.
