Is “Headers and client library minor version mismatch” error is fixed in 4.5.1?… As we understand, its not an error, it was a message suppressed in earlier WP version which is rightfully been revoked in WP 4.5… But is there a simple way we can fix this thru dashboard or a pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party?..

  Thank you for the report! We’ve seen a few other reports of similar warnings, so I’ve added a fix for it – see #36629 for further information. The fix is in the just-released 4.5.1-RC2 package.

  Thanks for the reminder! I just refreshed the nightly build for the 4.5 branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch"., you should see 4.5.1-RCrelease candidate One of the final stages in the version release cycle, this version signals the potential to be a final release to the public.
