Just a quick review of some interesting changes – from the updated 3.2.4 platform
Live theme previews
Try on New Themes
Gone 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 before activating a new theme. Note: this feature is available for installed themes only.
Customize Current Theme
Satisfy 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.
Better Captions
HTML Support
Basic 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.
