Tl’dr: No, you may not post a release more than once. Even with a major update to a release, it is not allowed to post another thread. Just update the old one.
From this post: Releases Rules and FAQ
Please keep the forums tidy for example by combining similar releases into one topic and not reposting your releases, use your current topic to post updates. You may only post new topics every 12 hours.
Though sometimes it really grinds my gears seeing some users doing the same stuff over and over with a different color and logo.
