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.
6 inside ninety days
No date, but on the way out
4Still works. Do not start anything new on it.
- no dateannounced 1 Oct 2022Trigger.Once in Structured Streaming Feature Streaming Trigger intervals in Structured Streaming
Deprecated since Databricks Runtime 11.3 LTS, and still all over older tutorials.
Use Trigger.AvailableNow, which processes in several batches instead of one and does not fall over on a large backlog.
- no dateannounced 1 Jan 2026dbx by Databricks Labs Feature Ecosystem & Tools Databricks Labs, the tools around the platform Declarative Automation Bundles and the Databricks CLI
No longer actively maintained. Its own README points elsewhere.
Deployments move to bundles. Expect to find dbx in repositories for years yet.
- no dateannounced 1 Jan 2026Hyperopt Feature Experiments
The open-source project is no longer maintained and it is gone from the machine learning runtime after 16.4 LTS.
Optuna on a single node, or Ray Tune when the search has to be distributed.
- no dateannounced 1 Jan 2026Personal access tokens Feature Workspace
Now documented as the legacy way to authenticate.
Use OAuth, and in continuous integration use workload identity federation rather than a long-lived token in a secret.
Already gone
1Here because older tutorials still recommend them, and because an incident on one of these starts with an upgrade.
- 43 days ago31 Jul 2026The legacy SQL editor Feature SQL Editor
Retired in late July 2026, and the individual opt-out went with it.
Nothing to do beyond learning where things moved in the current editor.
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.
