- FIX – Shortcodes: Protect newlines inside of CDATA.
Below are the list of revised files:
Because this is a security release, everyone (all WordPress users) are strongly advised to immediately upgrade/update. If you have enabled Auto Updates then you don’t have to lift a finger as the system will automatically update the software for you. For those who didn’t, you can do it by logging in and heading to Dashboard > Updates then click Update Now.
If you prefer to do the update manually, you can do so by downloading the WordPress 4.2.4 zip file and uploading it via your FTP client.
Make sure you backup your database and other important or custom files. You might also want to deactivate all active plugins before proceeding with the upgrade to prevent any issues or hiccups.
Prevention is better than cure so please make time to update your WordPress blog/website ASAP. Keep safe and have a nice day!
