Description

For now, this issue aims to collect ideas for planning Apache Spark 4.0.0.

We will add more items which will be excluded from Apache Spark 3.5.0 (Feature Freeze: July 16th, 2023).

Spark 2: 2016.07 (2.0.0) ~ 2021.05 (2.4.8)
Spark 3: 2020.06 (3.0.0) ~ 2026.xx (3.5.x)
Spark 4: 2025.02 (4.0.0, NEW)
- January 15th 2025	Code freeze. Release branch cut.
- February 1st 2025	QA period. Focus on bug fixes, tests, stability and docs. Generally, no new features merged.
- February 15th 2025	Release candidates (RC), voting, etc. until final release passes
