WordPress 4.5.3 was released today, as announced on WordPress.org.
This is a security update, it is important to apply it as soon as possible. This fixes several vulnerabilities and resolves some bugs from earlier releases.
WordPress Update Process
Anyone that is set to receive minor or major/minor core updates on our system will automatically receive this. Our systems are starting to update sites now.
Updates from the WordPress auto-updater are also rolling out as I write this.
Minor updates like this are less likely to cause problems, and given the nature of this update, I would encourage you to update immediately if you don’t have auto-updates turned on.
If you haven’t updated to WordPress 4.5 yet, this would be a good time to do that as well, as most plugins/themes have been updated for compatibility.
As always, if you have any questions, please login to https://secure.lightningbase.com and open a ticket, we’ll be happy to help.
