What’s new in WordPress 4.2

WordPress 4.2 was released this week. This new release contains several improvements such as an improved ‘Press This’, extended Characters support, better plugin upgrades and Tumblr and Kickstarter oEmbed support.

New and improved ‘Press This’

Press This isn’t new, but it’s been revitalized with some new features.

Press This is a bookmarklet that you can drag and drop to your browser’s bookmarks bar or add to your mobile home screen. This allows you to easily publish any content on the web to your WordPress site with a simple click or tap.

Press This will now automatically find images, excerpt, and title for the content you are re-publishing and embed it to a post on the fly. This will make re-publishing the content a lot faster and easier.

Native Chinese, Japanese, Korean Character and Emoji symbol support

WordPress 4.2 will automatically switch your utf-8 database to utf8mb4. This means that WordPress can now use 4 byte characters rather than 3.

4 byte characters lets you use any Unicode character, which opens up support for Chinese, Japanese, Korean characters and symbols, including the popular emoticon characters emoji.

A better plugin update experience

Plugins are an essential component for websites and need constantly updated. With WordPress 4.2 you’re not taken away from the plugin update page while updating the plugins. This means less clicks, which is always a good thing.

Permalinks turn URLs like:
