This parameter affects major versions 7.5 and 8.1, and indeed should not affect 6.5.

The default value of tidb_enable_clustered_index is INT_ONLY in version 5.0.0.

From the release dates, version 7.5.0 is earlier than 6.5.10. It seems that the documentation should mention that the feature was introduced starting from version v6.5.x…

@MrSylar The documentation is very detailed, thumbs up :+1:

This parameter was introduced in 7.5 and is not available in 6.5.10.

So the RN for 6.5.10 has some issues.

Disabling tidb_enable_async_merge_global_stats is the default merge global status method in versions 7.1 and 6.5.

@hawkingrei

However, version 6.5 does not have this parameter. Writing it like this in the release notes can easily confuse users.
