Version 0.6.12 * if well-known URI detection fails with I/O errors, ignore it instead of aborting * if current-user-principal is not supported by the server, use the user-given URL is the principal URL * determine availability of CalDAV/CardDAV by whether a calendar/address-book home set is available * if DAV:displayname is not available for a collection, use its URL path instead * remove SSLPeerUnverifiedException handling (Apache HttpClient doesn't use this exception) * use Depth: 1 (instead of Depth: 0) for multi-get REPORT requests * don't display address books in "Select collections" UI if CardDAV is not available * don't display calendars in "Select collections" UI if CalDAV is not available With these changes, we have successfully tested: * Synology DiskStation with CalDAV+CardDAV * mail.de with CalDAV+CardDAV * web.de with CalDAV+CardDAV
