Latest commit 392fd09 Feb 16, 2017 @nylen nylen REST API: Cast revision author ID to int.
The `post_author` field is a string internally, but we need to cast it to an integer in the REST API.  This was already done for posts, but not for revisions.  The field is already declared as an integer in both controllers.

Fixes #39871.
