Just wanted to let everyone know that Concrete 8.5.9 is now available. This is hot on the heels of 8.5.8, but unfortunately 8.5.8 contained a couple bugs making it difficult to upload files, and inadvertently changed the requirements to PHP 5.6 (instead of 5.5.9). 8.5.9 should fix those issues. Those are the only changes.
If you’re running 8.5.8 it’s highly recommended you upgrade to 8.5.9. If you’re running an earlier version of 8, 8.5.9 is also highly recommended due to its improvements, security and bug fixes.
