[ajaygeorge]

@mshang816 did you resolve all the Missing Release Notes.?
e.g. The Clickhouse connector is marked as resolved but I don't see any Release notes for it.

[highker]

Are these general changes or connector-specific changes? They look to be misc items...

[rschlussel]

This note can be removed since it's included by the other distinct limit release note (cc: @kaikalur )

[ajaygeorge]

Mostly looking good now.
Some more minor comments.

• clickhouse

it looks to me the two commits just added a connector for clickhouse then upgraded it 1.1. So I think it only needs one entry in the release note, no ?
