Hi, All.
>From Today, we have `branch-3.0` as a tool of `Feature Freeze`.
https://github.com/apache/spark/tree/branch-3.0
All open JIRA issues whose type is `Improvement` or `New Feature` and had
`3.0.0` as a `Target Version` are changed accordingly first.
- Most of them are re-targeted to `3.1.0`.
- Some of them are resolved according to the JIRA content.
- Some unauthorized target versions are removed according to the
community policy.
To sum up, we have no open `Improvement/New Feature` JIRA issues targeting
`3.0.0` officially. For exceptional cases, we will discuss on them case by
case during `3.0.0 QA` phase.
Bests,
Dongjoon
