Today we are releasing bbPress 2.5.13, which fixes a few small bugs we’ve noticed since 2.5.12 was released, and also adds some sanitization to anonymous user data that went missing from previous versions.
If your site allows anonymous users (users without registered accounts) to create topics & replies in your forums, you’ll want to upgrade to 2.5.13 right away. This feature is not very widely used on public forums because spammers very aggressively target these kinds of sites, but for communities that rely on this feature, please know you can safely upgrade to 2.5.13 without any issues.
Also, remember that since bbPress 2.5.12, the minimum WordPress version allowed is 4.7. If you need to use a previous version of WordPress, you will want to continue to use 2.5.11.
bbPress 2.6 is still in the release candidate phase while we tie up some loose ends across WordPress.org, but I’ll let you know when it’s ready to go!
