hey folks! we're changing the innards of the code that renders posts on our way to turning on inline attachments; the post composer still isn't capable of creating posts with attachments inline, but we're working on that right now.
this change has a big risk of subtle bugs so we're starting by rolling it out to 10% of users; please keep an eye out for any posts that look weird in a way that you think might be unintentional, and let us know. we'll finish rolling it out hopefully within the next week or so.
