SabreDAV

A problem with the hiding action interface in the HTML browser for non-collections was fixed. Addressbook-query is now correctly returned from the {DAV:}supported-report-set property. Bugs in the groupwareserver.php example were fixed. A problem with rejecting PUT requests with Content-Range was fixed.

CardDAV support and an experimental WebDAV client were added.

The framework is now officially 'stable'. A workaround was included for a serious MS Office bug that caused saves to fail. API-level support for the ACL HTTP method was added. This only affects you if you're implementing custom filesystems with ACL support.

It's not possible to disable listing of nodes that are denied read access by ACL. A few properties in CalDAV classes have changed from private to protected. Issue 119 has been fixed: terrible things could happen when relying on guessBaseUri, the server was running on the root of the domain, and a user tried to access a file ending in .php. This is a slight BC break. Issue 118 has been fixed: lock tokens in If headers without a URI should be treated as the request URI, not 'all relevant URIs.

Support was added for big chunks of RFC3744 (ACL), with a couple of exceptions. Support for CalDAVProxy (calendar delegation) was added. All "principal" related functionality has been moved from Sabre_DAV_Auth to the new Sabre_DAVACL package. The Sabre_VObject package was added for easy iCalendar parsing. Sabre_CalDAV_ICSExportPlugin was added for supporting the "Subscribe to calendar" feature found in some calendaring tools. Many more bugs were fixed.
