• Added: MIME-Directory grouping support in the VObject library. This is very
  useful for people attempting to parse vcards.
• BC Break: Adding parameters with the VObject libraries now overwrites the
  previous parameter, rather than just add it. This makes more sense for 99% of
  the cases.
• BC Break: lib/Sabre.autoload.php is now removed in favor of
  lib/Sabre/autoload.php.
• Deprecated: Sabre_DAV_Directory is now deprecated and will be removed in a

  'action' to reduce the chance of collisions.

  (Issue 60).

• Added: VObject library can now automatically map iCalendar properties to
  custom classes.

1.4.3

• Fixed: datatype of lastmodified field in mysql.calendars.sql. Please change
  the DATETIME field to an INT to ensure this field will work correctly.

• Fixed: Issue 119: 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

• Fixed: Issue 118: Lock tokens in If headers without a uri should be treated as
  the request uri, not 'all relevant uri's.
• Fixed: Issue 120: PDO backend was incorrectly fetching too much locks in cases
  where there were similar named locked files in a directory.

1.4.1

• Fixed: Sabre_DAV_Locks_Backend_PDO returned too many locks.
• Fixed: Sabre_HTTP_Request::getHeader didn't return Content-Type when running
  on apache, so a few workarounds were added.
• Change: Slightly changed CalDAV Backend API's, to allow for heavy
  optimizations. This is non-bc breaking.

1.4.0

• Added: Partly RFC3744 ACL support.
• Added: Calendar-delegation (caldav-proxy) support.
• BC break: In order to fix Issue 99, a new argument had to be added to
  Sabre_DAV_Locks_Backend_*::getLocks classes. Consult the classes for details.
• Deprecated: Sabre_DAV_Locks_Backend_FS is now deprecated and will be removed
  in a later version. Use PDO or the new File class instead.

• Added: updateProperties event.
• Added: Principal listings and calendar-access can now be done privately,
  disallowing users from accessing or modifying other users' data.
• Added: You can now pass arrays to the Sabre_DAV_Server constructor. If it's an
  array with node-objects, a Root collection will automatically be created, and
  the nodes are used as top-level children.
• Added: The principal base uri is now customizable. It used to be hardcoded to
  'principals/[user]'.
• Added: getSupportedReportSet method in ServerPlugin class. This allows you to
  easily specify which reports you're implementing.
• Added: A '..' link to the HTML browser.
• Fixed: Issue 99: Locks on child elements were ignored when their parent nodes
  were deleted.

• Fixed: Issue 59: Allowing the user to override the authentication realm in
  Sabre_CalDAV_Server.
• Update: Issue 97: Looser time-range checking if there's a recurrence rule in
  an event. This fixes 'missing recurring events'.

1.3.0

• Added: childExists method to Sabre_DAV_ICollection. This is an api break, so
  if you implement Sabre_DAV_ICollection directly, add the method.
• Changed: Almost all HTTP method implementations now take a uri argument,
  including events. This allows for internal rerouting of certain calls. If you
  have custom plugins, make sure they use this argument. If they don't, they
  will likely still work, but it might get in the way of future changes.
• Changed: All getETag methods MUST now surround the etag with double-quotes.
  This was a mistake made in all previous SabreDAV versions. If you don't do
  this, any If-Match, If-None-Match and If: headers using Etags will work
  incorrectly. (Issue 85).
• Added: Sabre_DAV_Auth_Backend_AbstractBasic class, which can be used to easily
  implement basic authentication.
• Removed: Sabre_DAV_PermissionDenied class. Use Sabre_DAV_Forbidden instead.
• Removed: Sabre_DAV_IDirectory interface, use Sabre_DAV_ICollection instead.

• Fixed: If-Modified-Since and If-Unmodified-Since would be incorrect if the
  date is an exact match.
• Fixed: Support for multiple ETags in If-Match and If-None-Match headers.
• Fixed: Improved baseUrl handling.

• Updated: Refactoring in Sabre_CalDAV to make everything a bit more ledgable.
• Fixed: Issue 88, Issue 89: Fixed compatibility for running SabreDAV on
  Windows.
• Fixed: Issue 86: Fixed Content-Range top-boundary from 'file size' to 'file
  size'-1.
