Upgrading WordPress is typically fairly easy but you have to either upload every single file from the download or you have to weed what has been modified and what has not. Typically a list of modified files is provided by WordPress which makes it easy to follow along and upgrade your WP version however it is a pain to upload every single file in the release. The below article has two main objectives which first is to provide you an easy to read summary of enhancements, resolved bugs, and new features and second will be to provide you a zip file with only the modified files in the WordPress upgrade. We will do our best to provide such an article for all future WP releases within a couple days of the public release.
