The sorting order in the “Release Announcements” forum works differently than the other forums. You can not “bump” a topic there by posting it in. The sorting order is determined by when the post was originally created and a few other factors. You’re more than welcome to continue to post in the same topic, but keep in mind how the threads are sorted.

Thanks, that's quite useful to know. Yeah I ended up feeling like it was easier to just do it with individual threads after all so I don't have to try to shuffle content around. Maybe there's a benefit to one big thread (assuming it even gets seen), but for now individual threads are easier and given what you've said probably get seen more anyway unless you've got a huge following.
