We have seen a recent increase in replies to older threads that are no longer relevant to the current platform version.
In order to avoid confusing new users, we have started a clean-up effort of closing older threads that have been created more than a year ago. This project is to simply close threads (no content will be removed), so that if similar issues exist in the most recent platform update, the user must create a new thread.
Please note that during this project users may notice an increase in the "unread posts" count due to the thread closure notification.
Thank you for your understanding!
