We avoid the term "column filtering" here; we talk about column lists.
Maybe it could be "This release introduces row filtering for publishers
and the ability to specify an optional column list for each table".
Also, there are docs to this feature:

It's very strange to have jsonlog and pg_walinspect in the same
paragraph.  Also, pg_walinspect isn't either logging or configuration.
Maybe put it under "other notable changes"?
