## Summary Addresses the "Documented policy for how long we will support Spark versions" item on the 1.0.0 tracker (#4082). Adds two subsections under **Apache Spark Version Support** in `about/versioning_policy.md`: - **New Version Adoption** — Comet does not commit to a timeline for adopting a new Spark minor (effort varies by release). Supported status requires an official upstream GA; experimental support may be published for pre-GA releases (previews, RCs, snapshots) but is explicitly not a commitment and can lag, break, or be withdrawn at any time. - **Support Lifetime** — Comet aligns with the upstream Spark maintenance window. Once upstream ends maintenance for a Spark minor, Comet deprecates it in the next Comet minor release and removes it in the following one, giving at least one Comet minor release of prior notice. Example: Spark 3.4 deprecated in Comet 1.0.0, removed in Comet 1.1.0. Also adds a cross-link from `compatibility/spark-versions.md` back to the policy so users hitting a deprecation warning can find the rule behind it. The new "New Version Adoption" section links to the existing contributor guide (`adding_a_new_spark_version.md`) for the mechanical bring-up steps and experimental-to-supported promotion criteria. ## Test plan - [ ] Prettier check passes (`npx prettier "**/*.md" --write` — no diff) - [ ] `docs/source/about/versioning_policy.md` renders cleanly in Sphinx - [ ] Cross-link from `spark-versions.md` to `versioning_policy.md#apache-spark-version-support` resolves -- This is an automated message from the Apache Git Service.
