On the PHP.net site they've made an announcement about releases of all currently supported major PHP versions with bugfix/security releases.
The PHP development team announces the immediate availability of PHP [7.0.33, 7.1.25, and 7.2.13]. Five security-related issues were fixed in this release. All PHP 7.0 users are encouraged to upgrade to this version.
You can download these latest releases from either the main downloads page or windows.php.net for the Windows executables.
There's also a note for the PHP 7.0.33 release based on the release and support timelines: this will be the final release, of any kind, for the PHP 7.0.x branch including security support. If you haven't already upgraded past version 7.0.x, there's never been a better time!
