WordPress version 4.2 is newly available for download.
Update now to the new “Powell” WP release to take advantage of any security improvements it may include.
Named after legendary jazz pianist Bud Powell, WordPress 4.2 features smoother plugin updates, improved functionality for character-based languages like Japanese and Korean, easier previewing of themes in the Customizer, and a number of other improvements.
The WordPress clipping bookmarklet that makes content curation a breeze, Print This, has also been improved and updated.
Be sure to backup your WordPress install before updating to avoid any glitches!
