WordPress today released a new version which is WordPress 3.6 across everywhere. It’s called
WordPress 3.6 “Oscar”
The new version of WordPress 3.6 comes with a beautiful new blog-centric theme, bullet-proof autosave and post locking, a revamped revision browser, native support for audio and video embeds, and improved integrations with Spotify, Rdio, and SoundCloud.
Features: Revamped Revisions save every change and the new interface allows you to scroll easily through changes to see line-by-line who changed what and when.
Post Locking and Augmented Autosave will especially be a boon to sites where more than a single author is working on a post.
A new audio/video API gives you access to metadata like ID3 tags.
You can now choose HTML5 markup for things like comment and search forms, and comment lists.
