Micropub version 2.1.0 for WordPress was released. It contains no exciting new features as Micropub is fairly stable.

Micropub now checks WordPress capabilities more effectively. It will now throw an error if the user tries to edit a post authored by another user if they do not have that permission, for example.
Default Titles and captions weren’t being set for images when uploaded.
Fix a variety of timezone related bugs
Added support for the proposed draft scope. If the token has this scope and not the create scope, then it will only allow posts to be created as drafts.
Return the created URL in the Micropub response to support an automation use case.
Add filters to allow a custom post type or custom taxonomy to be set during creation.
No longer support the ‘post’ scope as permission to do anything. It will map to a combination of create and update.
Misc unit test tweaks for consistency.
