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.

This is not planning any more. If it is in production, it is this week’s work.

    DeepSeek V4 Pro (0813) Model Serving Foundation Model APIs

    DeepSeek V4 Pro (0813) is retired from Foundation Model APIs on 30 October 2026. Databricks names DeepSeek V4.1 Flash as the replacement.

    Move workloads to DeepSeek V4.1 Flash, and follow the deprecated and retired models guidance for anything pinned to the 0813 version.

    Genie One MCP Beta endpoint (/api/2.0/mcp/genie) APIplatform Agents Agent tools as Unity Catalog functions Model Context Protocol on Databricks Coding agents on Databricks, and how to keep them safe

    The Beta MCP endpoint for Genie One is deprecated. Genie One is now the MCP Service system.ai.genie_one_mcp, reached through Unity Gateway and asking for the ai-gateway OAuth scope instead of genie.

    Point clients at system.ai.genie_one_mcp and change the scope to ai-gateway. The per-space Genie Agent server at /api/2.0/mcp/genie/{genie_space_id} is a different endpoint and is not affected.

    Databricks Runtime 10.4 LTS Runtimeplatform Compute

    The last announced end of life among the old long-term support releases.

    Move the workloads still pinned to it. Anything this old will need testing, not just a version bump.

This quarter

1

Time to schedule the upgrade, not to start investigating it.

    Old-format OpenSharing recipient tokens Behaviour change Discover Sharing data with OpenSharing

    Tokens issued in the old format expire, at the latest, on this date.

    Rotate recipient credentials before then, or the sharing partner loses access without warning.

Within the year

2

Dated and certain. Put it in a plan while the plan is still cheap.

  1. in 96 days1 Feb 2027
    Databricks Runtime 14.3 LTS Runtimeplatform Compute

    Long-term support ends, so no more fixes and no more support tickets against it.

    Plan the jump to 16.4 LTS or later. Check the behaviour changes between them rather than assuming a clean swap.

  2. in 295 days19 Aug 2027
    Databricks Runtime 15.4 LTS Runtimeplatform Compute

    Long-term support ends.

    Still comfortable, but note it is the floor for several features, so upgrading unlocks as much as it costs.

Beyond a year

3

Far enough away to choose deliberately: build on the long-term support version, not the one ending first.

  1. in 559 days9 May 2028
    Databricks Runtime 16.4 LTS Runtimeplatform Compute

    Long-term support ends.

    A reasonable target for anything being upgraded today.

  2. in 725 days22 Oct 2028
    Databricks Runtime 17.3 LTS Runtimeplatform Compute

    Long-term support ends.

    The safer target if the workload can take the newer behaviour.

  3. in 956 days10 Jun 2029
    Databricks Runtime 18 LTS Runtimeplatform Compute

    Long-term support ends. The longest runway currently published.

    Where a new project should start.

No date, but on the way out

Still works. Do not start anything new on it.

  1. no dateannounced 1 Oct 2022
    Trigger.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.

  2. no dateannounced 1 Jan 2026
    Hyperopt 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.

  3. no dateannounced 1 Jan 2026
    Personal 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.

  4. no dateannounced 1 Jan 2026
    dbx 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.

  5. no dateannounced 18 Aug 2026
    Deprecated system table columns and schemas Behaviour change Catalog System tables

    Two lineage columns stopped being populated during 2026, and two schemas now hold empty tables.

    Queries against them return nothing rather than failing, which is the worse failure mode. Check any dashboard built on them.

Already gone

10

Here because older tutorials still recommend them, and because an incident on one of these starts with an upgrade.

  1. 241 days ago1 Mar 2026
    Databricks Runtime 12.2 LTS Runtimeplatform Compute

    Support ended in March 2026.

    Upgrade. There is no support path left for it.

  2. 166 days ago15 May 2026
    Llama 3.1 405B Model Serving

    Retired from pay-per-token in February 2026 and from provisioned throughput in May.

    The documented replacement is GPT OSS 120B.

  3. 105 days ago15 Jul 2026
    Databricks Runtime 18.0 Runtimeplatform Compute

    A non-long-term-support release, supported for about six months.

    Move to 18 LTS. This is the pattern for every non-LTS version, so pin to LTS unless you need something newer.

  4. 104 days ago16 Jul 2026
    GPT-5.1 Codex Max, Codex Mini and GPT-5.2 Codex Model Serving

    Three OpenAI coding models retired together in July 2026.

    GPT-5.5 replaces the Max and 5.2 variants, GPT-5.4 Codex Mini replaces the Mini.

  5. 89 days ago31 Jul 2026
    The 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.

  6. 67 days ago22 Aug 2026
    Databricks Runtime 13.3 LTS Runtimeplatform Compute

    Support ended in August 2026.

    Clusters pinned here are running unsupported. Treat any incident on them as an upgrade first.

  7. 44 days ago14 Sept 2026
    Workspace entitlement inheritance becomes mandatory Behaviour change Workspace

    The enforcement date for inherited entitlements, with no opt-out left.

    Check any automation that sets entitlements on system groups: that is what breaks.

  8. 28 days ago30 Sept 2026
    The Supervisor API APIplatform 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.

  9. 26 days ago2 Oct 2026
    Gemini 2.5 Flash and 2.5 Pro Model Serving

    Both retire on the same day, Flash from pay-per-token and Pro from provisioned throughput.

    Databricks points at Gemini 3.1 Pro or 3.5 Flash. Budget time for re-evaluating, not just renaming the endpoint.

  10. 19 days ago9 Oct 2026
    Claude Sonnet 4 on Foundation Model APIs Model Serving

    Retired from pay-per-token serving. Requests to it will stop working.

    Move to Claude Sonnet 4.6 and re-run your evaluations: a newer model is not a drop-in for prompt behaviour.

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.
