where_object_changes no longer supports reading YAML from a text
|
|
column. The old implementation was inaccurate, returning more records
|
|
than you wanted. This feature was deprecated in 8.1.0 and removed in
|
|
9.0.0. The json and jsonb datatypes are still supported. See
|

discussion at https://github.com/paper-trail-gem/paper_trail/pull/997
