6 months after the last major release, we just put sabre/dav 2.1 live.

I’m very excited to announce that we finally have support for CalDAV scheduling (rfc6638), which is a big deal and was hard to implement.

This means that invitations can get processed automatically, delivered to other CalDAV users, and clients that support scheduling will be able to accept or decline invites directly on the server, and ask for free-busy information.

We also now support vCard 4.0 (rfc6350), jCard (rfc7095) and converting between vCard 3, 4, and jCard using content-negotiation.

Thanks all! I hope it’s well received :)

The full announcement can be found on the website.

As usual, we also prepared a migration document if you are upgrading from and older version.
