WordPress 3.6 includes several new features such as post formats, audio/video embedding, autosave, post locking, and an improved user interface. Post formats allow categorizing posts visually as standard, gallery, video, or other types. Audio and video can now be embedded directly in posts. Autosave locally saves posts every 15 seconds to prevent loss of work. Post locking prevents simultaneous editing of the same post. The user interface was updated with a larger font, more spacing, and a darker sidebar. The new Twenty Thirteen theme is blog-focused and utilizes the new post formats.
