sabre/vobject 4.0.1 release

We just released sabre/vobject 4.0.1.

This version contains a small change related to iTIP messages. When we generate a CANCEL, message the object now contains a DTEND.

Upgrade sabre/vobject by running:

composer update sabre/vobject

If this didn't upgrade you to 4.0.1, make sure that your composer.json file has a line that looks like this:

"sabre/vobject" : "~4.0.1"

Full changelog of this release can be found on Github.
