sabre/dav 3.2.2 released

We just released sabre/dav 3.2.2. This release fixes a regression introduced with sabre/dav 3.2.1 related to CardDAV synchronization.

sabre/dav 3.2.1 released

We just released sabre/dav 3.2.1. This release improves syncing large calendars when using SQLite and adds a new feature that allows CardDAV clients to use property-filters when requesting addressbooks (thanks @DeepDiver1975).

sabre/uri 2.1.0 and 1.2.0 released

We just released sabre/uri 2.1.0 and 1.2.0. This release adds a new pure-php fallback parser for uris to work around two problems with PHP's parse_url(), which had trouble with uris that start with a scheme:/// (triple-slash) and relative uri containing an unencoded colon.
