Tracker issue apache#4082 (1.0.0 release) calls out a documented policy for how long Comet supports Spark versions. This adds two subsections under Apache Spark Version Support in the versioning policy: - New Version Adoption: Comet does not commit to a timeline for adopting a new Spark minor. Supported status requires an official upstream GA; experimental support may be published for pre-GA releases but is not a commitment. - Support Lifetime: Comet aligns with upstream Spark's maintenance window. Once upstream ends maintenance for a Spark minor, Comet deprecates it in the next minor release and removes it in the following one, giving at least one Comet minor release of prior notice. Also cross-links the compatibility page's deprecation warnings to the new policy section so users hitting a warning can find the rule behind it.
