I think you're overthinking it. It may seem like needless clutter, but a single topic for every newsworthy feature is probably going to be more effective than some complex system to ensure the same topic can be reused.

Though, it wouldn't be complex. When the Guild updates, place a description as the latest post, and retitle the thread with the current Guild version and the date.
