No there is none. A beta for testing purposes exists, but it's not recommended to use that in production. A lot of extensions still need to be upgraded and the core team is still working on two audits made available by the NLnet grant, for accessibility and for security. Of the former we have the report, the latter is still pending.
Our goal has always been to release V2 this year, but we really want to have it well tested before we do that.
