I just noticed this today: Description: Bleeding edge version of Sylpheed and from the website: Origin Sylpheed-Claws started as the bleeding-edge version of Sylpheed, in order to act as a testbed for new features for Sylpheed. The idea was to regularly resync with Hiroyuki's main branch, and vice-versa. Sylpheed-Claws then evolved into the stable extended version of Sylpheed, and is now an entity in its own right, mainly due to different goals and the fact that syncing both codebases doesn't happen anymore. So... yeah... they don't share codebases anymore, so it's not a bleeding edge version of Sylpheed. :)
