Most importantly, this fixes an issue where malicious actors can create accounts on closed-registration #WriteFreely instances running the previous v0.16 or below.
We've heard reports of this ACTIVELY being exploited today across many WriteFreely instances -- multi- and single-user.
We advise ALL WriteFreely admins to upgrade immediately. You may also notice many unwanted accounts on your instance that need to be manually cleaned up. We'll be adding admin tools to make this quicker soon.
