Change record status: 
Project: 
Introduced in branch: 
8.2.x
Introduced in version: 
8.2.0
Description: 

Previously, it was impossible to update comment entities using the standard PATCH method over core REST http.

Now, developers can use both JSON normalization/serialization and HAL+JSON to update a comment resource.

Example request:
Method: PATCH
URI: /comment/1
Header: Content-Type: application/json
Payload:

{
  "langcode":[{"value":"en"}],
  "subject":[{"value":"New Subject"}],
  "uid":[{"target_id":"1","url":"/discasaurus.com/user/1"}],
  "status":[{"value":"1"}],
  "comment_type":[{"target_id":"comment"}],
  "default_langcode":[{"value":"1"}],
  "comment_body":[{"value":"<p>New body...</p>","format":"basic_html"}]
}

The change was simultaneously introduced in 8.2.x and 8.1.x
