• The zip release ships with sabre/vobject 2.0.5.
• Changed: To be compatibile with MS Office 2011 for Mac, a workaround was
  removed that was added to support old versions of Windows XP (pre-SP3).
  Indeed! We needed a crazy workaround to work with one MS product in the past,
  and we can't keep that workaround to be compatible with another MS product.
• Fixed: expand-properties REPORT had incorrect values for the href element.
• Fixed: Range requests now work for non-seekable streams. (Thanks Alfred
  Klomp).
• Fixed: Changed serialization of {DAV:}getlastmodified and {DAV:}supportedlock
  to improve compatiblity with MS Office 2011 for Mac.
• Changed: reverted the automatic translation of 'DAV:' xml namespaces to
  'urn:DAV' when parsing files. Issues were reported with libxml 2.6.32, on a
  relatively recent debian release, so we'll wait till 2015 to take this one out
  again.
• Added: Sabre_DAV_Exception_ServiceUnavailable, for emitting 503's.
