This thread is for reporting bugs or discussing recent changes to the site. This is the replacement for the Danbooru 2 Issues Topic.
You can also make feature requests here. If your request needs a lot of discussion, you can also open a new thread for it.
If you're reporting a bug or have a feature request, it's a good idea to also report it on Github. To do that, just go to https://github.com/danbooru/danbooru/issues/new. Otherwise it's easy for things to get lost in the shuffle when they're buried in a long megathread.
For changelogs, see the Danbooru changelog thread.
