Databricks vs Fission: at a glance
What is Databricks?
Databricks lands DBR 18.2 GA on Spark 4.1; the 18.x line is the active story, older LTS pages are mostly doc refreshes.
The substantive shipping event in the window is Databricks Runtime 18.2 GA on May 4, the latest minor in a fast 18.x cadence on Spark 4.1.0 (18.0 in January, 18.1 in March, 18.2 Beta on April 8, GA on May 4). The rest of the recent feed is an April 13 documentation refresh that updated release notes for older LTS versions — 14.3, 15.4, 16.4, 17.3, 13.3 — without new shipping behind them.
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

Databricks
5.0INFRA · APISANALYTICS
Databricks lands DBR 18.2 GA on Spark 4.1; the 18.x line is the active story, older LTS pages are mostly doc refreshes.
◆ Current state
The substantive shipping event in the window is Databricks Runtime 18.2 GA on May 4, the latest minor in a fast 18.x cadence on Spark 4.1.0 (18.0 in January, 18.1 in March, 18.2 Beta on April 8, GA on May 4). The rest of the recent feed is an April 13 documentation refresh that updated release notes for older LTS versions — 14.3, 15.4, 16.4, 17.3, 13.3 — without new shipping behind them.
◆ Where it's heading
Databricks is pushing Spark 4.1 hard through the runtime line: JDK 21 default in 18.x, breaking changes around NULL preservation and partition columns, aggressive deprecation of older behaviors (input_file_name removal, AWS SDK v1 shading). The 18.x cadence is roughly one minor every six weeks, and 16.4 LTS is acting as the bridge for customers needing to migrate Scala 2.12 code to 2.13 before they can move to 17 or 18.
◆ Prediction
Expect an 18.x LTS designation later in 2026 once the line stabilizes, with continued behavioral hardening and more shaded dependency cleanup. Doc refreshes for older LTS versions — particularly 13.3 LTS, which is close to its August 2026 end-of-support — will likely keep landing as Databricks pushes customers up the runtime stack.

Fission's release feed carries only RC tags, and none of them say what shipped
◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely.

The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
