Live Theme Previews
Try on New ThemesGone are the days of rushing to update your header, background, and the like as soon as you activate a new theme. You can now customize these options beforeactivating a new theme. Note: this feature is available for installed themes only.
Customize Current ThemeSatisfy your curiosity and try on a fresh coat of paint — you can also use the live preview mode to customize your current theme. Look for the Customize link on the Themes screen.
Flexible SizesYou can decide for yourself how tall or wide your custom header image should be. From now on, themes will provide a recommended image size for custom headers rather than a fixed requirement. Note: this feature requires theme support.
Choose from Media LibraryTired of re-uploading the same custom header image every time you check out a new theme? Now you can choose header images from your media library for easier customization.
Share Tweets with StyleYou can now embed individual tweets in posts. It includes action links that allow readers to reply to, retweet, and favorite the tweet without leaving your site. Just paste a tweet URL on its own line. This works with URLs from some other sites, too. For more, see the Codex article on Embeds.
HTML SupportBasic HTML support has been added to the caption field in the image uploader. This allows you to add links — great for photo credits or licensing details — and basic formatting such as bold and italicized text.
