Tuwunel should not be recommended to new users.
Keep in mind the claim of being official is not true: this is a claim by one of the former co-maintainers of conduwuit, to claim legitimacy over other projects like continuwuity. Additionally, tuwunel's maintainer has openly made threats against the maintainers of continuwuity, aswell as being formally banned from the foundation for actively abusing protocol exploits. I'm not sure I'd trust a project primarily maintained by them for these reasons. Additionally, it's maintainer appears to currently also be pushing for publishing how to exploit the security vulnerabilities from the upcoming security release.
— aur tuwunel-git, corroborated by nex (CoI: continuwuity maintainer; has received death thrrats from tuwunel developers) in #offtopic:continuwuity.org a few upgrades ago
If you're already running a homeserver, I don't care; switching homeserver software is hell. I run a continuwuity at pool.net.eu.org, which has been doing fine.
