+Since December 1 2024, pub.drawpile.net no longer allows hosting sessions with the old version of Drawpile on it. That version was released over 3 years ago. Automatic reminders were sent to every session that was hosted with the old version for the past half year asking folks to tell us if there's a reason they can't update and nothing came up.
+
+The reason we're updating is because the old version is a good bit more annoying to administer. Future versions of Drawpile also won't be infinitely backward-compatible, so administrators would need to keep a bunch of old versions around to handle reported sessions, which they don't want to do.
+
+If pub.drawpile.net is telling you that you can't host with your old version, you can update it by installing the new version over it. You can get that <a href="https://drawpile.net/">from drawpile.net</a>.
+
+If for some reason that isn't an option, tell us about it. Ideally, we can fix whatever issue you're having. Check out <a href="https://drawpile.net/help/">the main help page</a> for how to get in contact.
+
+Otherwise, while it's not recommended to stick around on old, unsupported software, there's still servers that allow hosting with the old version. Most of the ones you can find <a href="https://drawpile.net/communities/">on the community servers page</a> still allow it. You can also <a href="/help/common/hosting#hosting-on-your-computer">host on your own computer</a>, with some network setup required, or set up <a href="/help/server/dedicatedserver">your own dedicated server</a>.
