[ywkaras]

For #10683 , I don't know if the deprecation needs to be move from What's New to Upgrading.

[ywkaras]

#9334 was cleanup to #6609 . #6609 is a plugin API extension . It's documented but not noted in What's New. If the extension was present in 9.x , it wasn't documented at all.

[maskit]

Updated the list based on the query results.

[brbzull0]

shouldn't we also track #11025 as new feature? (txn_box experimental plugin?) Original PR have no new feature tag, probably it should have it.
