If you’re still on an older version of ClassicPress, we recommend that you update your site(s) as soon as possible.
The changes in ClassicPress
1.0.0-beta2 are pulled from WordPress 4.9.9, which has the same security fixes as WordPress 5.0.1.
We’ve also fixed all known cases of an issue where certain security scanners were incorrectly detecting ClassicPress sites as WordPress 1.0.0.
