-	  removed in a future version.
-	* Fixed: Restoring old setting after changing
-	  libxml_disable_entity_loader.
-	* Fixed: Issue #422: Preconditions were not being set on PUT on non-

-	* Changed: Sabre\DAV\Client::verifyPeer is now a protected property
-	 (instead of private).

-
-1.7.5-stable (2013-03-01)
-	* The zip release ships with sabre/vobject 2.0.6.
-	* Change: No longer advertising support for 4.0 vcards. iOS and OS X
-	  address book don't handle this well, and just advertising 3.0 support
-	  seems like the most logical course of action.
-	* Added: ->setVerifyPeers to Sabre_DAV_Client (greatly resisting against
-	  it, don't use this..).
-
-1.7.4-stable (2013-01-19)
-	* 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.
-
-1.7.3-stable (2012-12-01)

-	  functionality.
-	* Fixed: Issue 174. Sending back HTTP/1.0 for requests with this version.
-
-1.7.2-stable (2012-11-08)
-	* The zip release ships with sabre/vobject 2.0.5.

-	  property-search'.
-	* Fixed: [#153] Allowing for relative http principals in iMip requests.
-	* Added: Support for cs:first-name and cs:last-name properties in sharing
-	  invites.
-	* Fixed: Made a bunch of properties protected, where they were private
-	  before.
-	* Added: Some non-standard properties for sharing to improve
-	  compatibility.
-	* Fixed: some bugfixes in postgres sql script.
-	* Fixed: When requesting some properties using PROPFIND, they could show
-	  up as both '200 Ok' and '403 Forbidden'.
-	* Fixed: calendar-proxy principals were not checked for deeper principal
-	  membership than 1 level.
-	* Fixed: setGroupMemberSet argument now correctly receives relative
-	  principal urls, instead of the absolute ones.
-	* Fixed: Server class will filter out any bonus properties if any extra
-	  were returned. This means the implementor of the IProperty class can be
-	  a bit lazier when implementing.
-
-Note: bug numbers after this line refer to Google Code tickets. We're using
-github now.
-
-1.7.1-stable (2012-10-07)
-	* Fixed: include path problem in the migration script.
-
-1.7.0-stable (2012-10-06)
-	* BC Break: The calendarobjects database table has a bunch of new
-	  fields, and a migration script is required to ensure everything will
-	  keep working. Read the wiki for more details.
-	* BC Break: The ICalendar interface now has a new method: calendarQuery.
-	* BC Break: In this version a number of classes have been deleted, that
-	  have been previously deprecated. Namely:
-		- Sabre_DAV_Directory (now: Sabre_DAV_Collection)
-		- Sabre_DAV_SimpleDirectory (now: Sabre_DAV_SimpleCollection)
-	* BC Break: Sabre_CalDAV_Schedule_IMip::sendMessage now has an extra
-	  argument. If you extended this class, you should fix this method. It's
-	  only used for informational purposes.
-	* BC Break: The DAV: namespace is no longer converted to urn:DAV. This was
-	  a workaround for a bug in older PHP versions (pre-5.3).
-	* Removed: Sabre.includes.php was deprecated, and is now removed.
-	* Removed: Sabre_CalDAV_Server was deprecated, and is now removed. Please
-	  use Sabre_DAV_Server and check the examples in the examples/ directory.
-	* Changed: The Sabre_VObject library now spawned into it's own project!
-	  The VObject library is still included in the SabreDAV zip package.
-	* Added: Experimental interfaces to allow implementation of caldav-sharing.
-	  Note that no implementation is provided yet, just the api hooks.
-	* Added: Free-busy reporting compliant with the caldav-scheduling
-	  standard. This allows iCal and other clients to fetch other users'
-	  free-busy data.
-	* Added: Experimental NotificationSupport interface to add
-	  caldav notifications.
-	* Added: VCF Export plugin. If enabled, it can generate an export of an
-	  entire addressbook.
-	* Added: Support for PATCH using a SabreDAV format, to live-patch files.
-	* Added: Support for Prefer: return-minimal and Brief: t headers for
-	  PROPFIND and PROPPATCH requests.
-	* Changed: Responsibility for dealing with the calendar-query is now
-	  moved from the CalDAV plugin to the CalDAV backends. This allows for
-	  heavy optimizations.
-	* Changed: The CalDAV PDO backend is now a lot faster for common
-	  calendar queries.
-	* Changed: We are now using the composer autoloader.
-	* Changed: The CalDAV backend now all implement an interface.
-	* Changed: Instead of Sabre_DAV_Property, Sabre_DAV_PropertyInterface is
-	  now the basis of every property class.
-	* Update: Caching results for principal lookups. This should cut down
-	  queries and performance for a number of heavy requests.
-	* Update: ObjectTree caches lookups much more aggresively, which will help
-	  especially speeding up a bunch of REPORT queries.
-	* Added: Support for the schedule-calendar-transp property.
-	* Fixed: Marking both the text/calendar and text/x-vcard as UTF-8
-	  encoded.
-	* Fixed: Workaround for the SOGO connector, as it doesn't understand
-	  receiving "text/x-vcard; charset=utf-8" for a contenttype.
-	* Added: Sabre_DAV_Client now throws more specific exceptions in cases
-	  where we already has an exception class.
-	* Added: Sabre_DAV_PartialUpdate. This plugin allows you to use the
-	  PATCH method to update parts of a file.
-	* Added: Tons of timezone name mappings for Microsoft Exchange.
-	* Added: Support for an 'exception' event in the server class.
-	* Fixed: Uploaded VCards without a UID are now rejected. (thanks Dominik!)
-	* Fixed: Rejecting calendar objects if they are not in the
-	  supported-calendar-component list. (thanks Armin!)
-	* Fixed: Issue 219: serialize() now reorders correctly.
-	* Fixed: Sabre_DAV_XMLUtil no longer returns empty $dom->childNodes
-	  if there is whitespace in $dom.
-	* Fixed: Returning 409 Conflict instead of 500 when an attempt is made to
-	  create a file as a child of something that's not a collection.
-	* Fixed: Issue 237: xml-encoding values in SabreDAV error responses.
-	* Fixed: Returning 403, instead of 501 when an unknown REPORT is
-	  requested.
-	* Fixed: Postfixing slash on {DAV:}owner properties.
-	* Fixed: Several embarrassing spelling mistakes in docblocks.

-	  arbitrary file on windows servers. (CVE-2013-1939).
-
-1.6.7-stable (2013-03-01)
-	* Change: No longer advertising support for 4.0 vcards. iOS and OS X
-	  address book don't handle this well, and just advertising 3.0 support
-	  seems like the most logical course of action.
-	* Added: ->setVerifyPeers to Sabre_DAV_Client (greatly resisting against
-	  it, don't use this..).
-
-1.6.6-stable (2013-01-19)
-	* Fixed: Backported a fix for broken XML serialization in error responses.
-	 (Thanks @DeepDiver1975!)

-	  requests.
-	* Fixed: Problem with POST requests to the outbox if mailto: was not lower
-	  cased.
-	* Fixed: Yearly recurrence rule expansion on leap-days no behaves
-	  correctly.
-	* Fixed: Correctly checking if recurring, all-day events with no dtstart
-	  fall in a timerange if the start of the time-range exceeds the start of
-	  the instance of an event, but not the end.
-	* Fixed: All-day recurring events wouldn't match if an occurence ended
-	  exactly on the start of a time-range.
-	* Fixed: HTTP basic auth did not correctly deal with passwords containing
-	  colons on some servers.
-	* Fixed: Issue 228: DTEND is now non-inclusive for all-day events in the

-	  tuesday of the month, if this day did not exist.
-	* Added: New HTTP status codes from draft-nottingham-http-new-status-04.
-
-1.6.1-stable (2012-03-05)
-	* Added: createFile and put() can now return an ETag.
-	* Added: Sending back an ETag on for operations on CardDAV backends. This
-	  should help with OS X 10.6 Addressbook compatibility.

-	  implement the getSupportedPrivilegeSet method. See website for details.
-	* BC Break: Moved functions from Sabre_CalDAV_XMLUtil to
-	  Sabre_VObject_DateTimeParser.
-	* BC Break: The Sabre_DAVACL_IPrincipalCollection now has two new methods:
-	  'searchPrincipals' and 'updatePrincipal'.
-	* BC Break: Sabre_DAV_ILockable is removed and all related per-node
-	  locking functionality.
-	* BC Break: Sabre_DAV_Exception_FileNotFound is now deprecated in favor of
-	  Sabre_DAV_Exception_NotFound. The former will be removed in a later
-	  version.
-	* BC Break: Removed Sabre_CalDAV_ICalendarUtil, use Sabre_VObject instead.
-	* BC Break: Sabre_CalDAV_Server is now deprecated, check out the
-	  documentation on how to setup a caldav server with just
-	  Sabre_DAV_Server.
-	* BC Break: Default Principals PDO backend now needs a new field in the
-	  'principals' table. See the website for details.
-	* Added: Ability to create new calendars and addressbooks from within the
-	  browser plugin.
-	* Added: Browser plugin: icons for various nodes.

-	  be specified in Sabre_VObject_Property::$classMap.
-	* Added: Ability for plugins to tell the ACL plugin which principal
-	  plugins are searchable.
-	* Added: [DAVACL] Per-node overriding of supported privileges. This allows
-	  for custom privileges where needed.
-	* Added: [DAVACL] Public 'principalSearch' method on the DAVACL plugin,
-	  which allows for easy searching for principals, based on their
-	  properties.
-	* Added: Sabre_VObject_Component::getComponents() to return a list of only
-	  components and not properties.
-	* Added: An includes.php file in every sub-package (CalDAV, CardDAV, DAV,
-	  DAVACL, HTTP, VObject) as an alternative to the autoloader. This often
-	  works much faster.
-	* Added: Support for the 'Me card', which allows Addressbook.app users
-	  specify which vcard is their own.
-	* Added: Support for updating principal properties in the DAVACL principal
-	  backends.
-	* Changed: Major refactoring in the calendar-query REPORT code. Should
-	  make things more flexible and correct.
-	* Changed: The calendar-proxy-[read|write] principals will now only appear
-	  in the tree, if they actually exist in the Principal backend. This should
-	  reduce some problems people have been having with this.
-	* Changed: Sabre_VObject_Element_* classes are now renamed to
-	  Sabre_VObject_Property. Old classes are retained for backwards
-	  compatibility, but this will be removed in the future.

-	  CalDAV backend, allowing for more optimizations.
-	* Fixed: Much faster implementation of Sabre_DAV_URLUtil::encodePath.
-	* Fixed: {DAV:}getcontentlength may now be not specified.
-	* Fixed: Issue 66: Using rawurldecode instead of urldecode to decode paths
-	  from clients. This means that + will now be treated as a literal rather
-	  than a space, and this should improve compatibility with the Windows
-	  built-in client.
-	* Added: Sabre_DAV_Exception_PaymentRequired exception, to emit HTTP 402
-	  status codes.
-	* Added: Some mysql unique constraints to example files.
-	* Fixed: Correctly formatting HTTP dates.
-	* Fixed: Issue 94: Sending back Last-Modified header for 304 responses.

-	* Changed: Properties are now also automatically mapped to their
-	  appropriate classes, if they are created using the add() or __set()
-	  methods.
-	* Changed: Cloning VObject objects now clones the entire tree, rather than
-      just the default shallow copy.
-	* Added: Support for recurrence expansion in the CALDAV:calendar-multiget
-	  and CALDAV:calendar-query REPORTS.
-	* Changed: CalDAV PDO backend now sorts calendars based on the internal
-	  'calendarorder' field.
-	* Added: Issue 181: Carddav backends may no optionally not supply the carddata in
-	  getCards, if etag and size are specified. This may speed up certain
-	  requests.
-	* Added: More arguments to beforeWriteContent and beforeCreateFile (see
-	  WritingPlugins wiki document).
-	* Added: Hook for iCalendar validation. This allows us to validate
-	  iCalendar objects when they're uploaded. At the moment we're just
-	  validating syntax.
-	* Added: VObject now support Windows Timezone names correctly (thanks
-	  mrpace2).
-	* Added: If a timezonename could not be detected, we fall back on the
-	  default PHP timezone.
-	* Added: Now a Composer package (thanks willdurand).
-	* Fixed: Support for \N as a newline character in the VObject reader.
-	* Added: afterWriteContent, afterCreateFile and afterUnbind events.
-	* Added: Postgresql example files. Not part of the unittests though, so
-	  use at your own risk.
-	* Fixed: Issue 182: Removed backticks from sql queries, so it will work
-	  with Postgres.
-
-1.5.9-stable (2012-04-16)

-	  quotes. (Fixes emClient compatibility).
-
-1.5.8-stable (2012-02-22)
-	* Fixed: Issue 95: Another timezone parsing issue, this time in
-	  calendar-query.
-

-	* Fixed: Issue 191: beforeUnlock was triggered twice.
-

-	* Fixed: DATE-TIME encoding was wrong in VObject. (we used 'DATETIME').

-	* Added: An experimental WebDAV client.
-	* Added: MIME-Directory grouping support in the VObject library. This is
-	  very useful for people attempting to parse vcards.

-	  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 future version. Use Sabre_DAV_Collection instead.

-	  protected.
-	* 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 file ending in .php. This is a slight BC break.
-	* 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

-
-1.4.1-beta (2011-02-26)
-	* 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.

-	* Added: Partly RFC3744 ACL support.
-	* Added: Calendar-delegation (caldav-proxy) support.

-	  removed in a later version. Use PDO or the new File class instead.

-	  To use: Add the Sabre_CalDAV_ICSExportPlugin, and add ?export to your
-	  calendar url.

-	  hardcoded to 'principals/[user]'.

-	  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 (2010-10-14)
-	* 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.

-	  available.
-	* Added: Cache layer in the ObjectTree.
-	* Added: Tree classes now have a delete and getChildren method.

-	  ledgable.
-	* Fixed: Issue 88, Issue 89: Fixed compatibility for running SabreDAV on
-	   Windows.

-	* Fixed: Improved unittests and build system
-
-1.0.4-stable (2010-01-11)
-	* Fixed: needed 2 different releases. One for googlecode and one for

-
-1.0.3-stable (2010-01-11)

-	* Changed: Custom complex properties and exceptions now get an instance of
-	  Sabre_DAV_Server as their first argument in serialize()
-	* Changed: Href complex property now prepends server's baseUri
-	* Changed: delete before an overwriting copy/move is now handles by server
-	  class instead of tree classes
-	* Changed: events must now explicitly return false to stop execution.
-	  Before, execution would be stopped by anything loosely evaluating to
-	  false.
-	* Changed: the getPropertiesForPath method now takes a different set of
-	  arguments, and returns a different response. This allows plugin
-	  developers to return statuses for properties other than 200 and 404. The
-	  hrefs are now also always calculated relative to the baseUri, and not
-	  the uri of the request.
-	* Changed: generatePropFindResponse is renamed to generateMultiStatus, and
-	  now takes a list of properties similar to the response of
-	  getPropertiesForPath. This was also needed to improve flexibility for
-	  plugin development.
-	* Changed: Auth plugins are no longer included. They were not yet stable
-	  quality, so they will probably be reintroduced in a later version.
-	* Changed: PROPPATCH also used generateMultiStatus now.
-	* Removed: unknownProperties event. This is replaced by the
-	  afterGetProperties event, which should provide more flexibility.
-	* Fixed: Only calling getSize() on IFile instances in httpHead()
-	* Added: beforeBind event. This is invoked upon file or directory creation
-	* Added: beforeWriteContent event, this is invoked by PUT and LOCK on an
-	  existing resource.
-	* Added: beforeUnbind event. This is invoked right before deletion of any
-	  resource.
-	* Added: afterGetProperties event. This event can be used to make
-	  modifications to property responses.
-	* Added: beforeLock and beforeUnlock events.
-	* Added: afterBind event.
-	* Fixed: Copy and Move could fail in the root directory. This is now
-	  fixed.
-	* Added: Plugins can now be retrieved by their classname. This is useful
-	  for inter-plugin communication.
-	* Added: The Auth backend can now return usernames and user-id's.
-	* Added: The Auth backend got a getUsers method
-	* Added: Sabre_DAV_FSExt_Directory now returns quota info
-
-0.12.1-beta (2009-09-11)
-	* Fixed: UNLOCK bug. Unlock didn't work at all
-
-0.12-beta (2009-09-10)
-	* Updated: Browser plugin now shows multiple {DAV:}resourcetype values
-	  if available.
-	* Added: Experimental PDO backend for Locks Manager
-	* Fixed: Sending Content-Length: 0 for every empty response. This
-	  improves NGinx compatibility.
-	* Fixed: Last modification time is reported in UTC timezone. This improves
-	  Finder compatibility.
-
-0.11-beta (2009-08-11)
-	* Updated: Now in Beta
-	* Updated: Pear package no longer includes docs/ directory. These just
-	  contained rfc's, which are publically available. This reduces the
-	  package from ~800k to ~60k
-	* Added: generatePropfindResponse now takes a baseUri argument
-	* Added: ResourceType property can now contain multiple resourcetypes.
-	* Fixed: Issue 13.
-
-0.10-alpha (2009-08-03)
-	* Added: Plugin to automatically map GET requests to non-files to
-	  PROPFIND (Sabre_DAV_Browser_MapGetToPropFind). This should allow
-	  easier debugging of complicated WebDAV setups.
-	* Added: Sabre_DAV_Property_Href class. For future use.
-	* Added: Ability to choose to use auth-int, auth or both for HTTP Digest
-	  authentication. (Issue 11)
-	* Changed: Made more methods in Sabre_DAV_Server public.
-	* Fixed: TemporaryFileFilter plugin now intercepts HTTP LOCK requests
-	  to non-existent files. (Issue 12)
-	* Added: Central list of defined xml namespace prefixes. This can reduce
-	  Bandwidth and legibility for xml bodies with user-defined namespaces.
-	* Added: now a PEAR-compatible package again, thanks to Michael Gauthier
-	* Changed: moved default copy and move logic from ObjectTree to Tree class
-
-0.9-alpha (2009-07-21)
-	* Changed: Major refactoring, removed most of the logic from the Tree
-	  objects. The Server class now directly works with the INode, IFile
-	  and IDirectory objects. If you created your own Tree objects,
-	  this will most likely break in this release.
-	* Changed: Moved all the Locking logic from the Tree and Server classes
-	  into a separate plugin.
-	* Changed: TemporaryFileFilter is now a plugin.
-	* Added: Comes with an autoloader script. This can be used instead of
-	  the includer script, and is preferred by some people.
-	* Added: AWS Authentication class.
-	* Added: simpleserversetup.py script. This will quickly get a fileserver
-	  up and running.
-	* Added: When subscribing to events, it is now possible to supply a
-	  priority. This is for example needed to ensure that the Authentication
-	  Plugin is used before any other Plugin.
-	* Added: 22 new tests.
-	* Added: Users-manager plugin for .htdigest files. Experimental and
-	  subject to change.
-	* Added: RFC 2324 HTTP 418 status code
-	* Fixed: Exclusive locks could in some cases be picked up as shared locks
-	* Fixed: Digest auth for non-apache servers had a bug (still not actually
-	  tested this well).
-
-0.8-alpha (2009-05-30)
-	* Changed: Renamed all exceptions! This is a compatibility break. Every
-	  Exception now follows Sabre_DAV_Exception_FileNotFound convention
-	  instead of Sabre_DAV_FileNotFoundException.
-	* Added: Browser plugin now allows uploading and creating directories
-	  straight from the browser.
-	* Added: 12 more unittests
-	* Fixed: Locking bug, which became prevalent on Windows Vista.
-	* Fixed: Netdrive support
-	* Fixed: TemporaryFileFilter filtered out too many files. Fixed some
-	  of the regexes.
-	* Fixed: Added README and ChangeLog to package
-
-0.7-alpha (2009-03-29)
-	* Added: System to return complex properties from PROPFIND.
-	* Added: support for {DAV:}supportedlock.
-	* Added: support for {DAV:}lockdiscovery.
-	* Added: 6 new tests.
-	* Added: New plugin system.
-	* Added: Simple HTML directory plugin, for browser access.
-	* Added: Server class now sends back standard pre-condition error xml
-	bodies. This was new since RFC4918.
-	* Added: Sabre_DAV_Tree_Aggregrate, which can 'host' multiple Tree objects
-	into one.
-	* Added: simple basis for HTTP REPORT method. This method is not used yet,
-	but can be used by plugins to add reports.
-	* Changed: ->getSize is only called for files, no longer for collections.
-	r303
-	* Changed: Sabre_DAV_FilterTree is now Sabre_DAV_Tree_Filter
-	* Changed: Sabre_DAV_TemporaryFileFilter is now called
-	Sabre_DAV_Tree_TemporaryFileFilter.
-	* Changed: removed functions (get(/set)HTTPRequest(/Response)) from Server
-	class, and using a public property instead.
-	* Fixed: bug related to parsing proppatch and propfind requests. Didn't
-	show up in most clients, but it needed fixing regardless. (r255)
-	* Fixed: auth-int is now properly supported within HTTP Digest.
-	* Fixed: Using application/xml for a mimetype vs. text/xml as per RFC4918
-	sec 8.2.
-	* Fixed: TemporaryFileFilter now lets through GET's if they actually
-	exist on the backend. (r274)
-	* FIxed: Some methods didn't get passed through in the FilterTree (r283).
-	* Fixed: LockManager is now slightly more complex, Tree classes slightly
-	less. (r287)
-
-0.6-alpha (2009-02-16)
-	* Added: Now uses streams for files, instead of strings.
-	  This means it won't require to hold entire files in memory, which can be
-	  an issue if you're dealing with big files. Note that this breaks
-	  compatibility for put() and createFile methods.
-	* Added: HTTP Digest Authentication helper class.
-	* Added: Support for HTTP Range header
-	* Added: Support for ETags within If: headers
-	* Added: The API can now return ETags and override the default Content-Type
-	* Added: starting with basic framework for unittesting, using PHPUnit.
-	* Added: 49 unittests.
-	* Added: Abstraction for the HTTP request.
-	* Updated: Using Clark Notation for tags in properties. This means tags
-	are serialized as {namespace}tagName instead of namespace#tagName
-	* Fixed: HTTP_BasicAuth class now works as expected.
-	* Fixed: DAV_Server uses / for a default baseUrl.
-	* Fixed: Last modification date is no longer ignored in PROPFIND.
-	* Fixed: PROPFIND now sends back information about the requestUri even
-	  when "Depth: 1" is specified.
-
-0.5-alpha (2009-01-14)
-	* Added: Added a very simple example for implementing a mapping to PHP
-	  file streams. This should allow easy implementation of for example a
-	  WebDAV to FTP proxy.
-	* Added: HTTP Basic Authentication helper class.
-	* Added: Sabre_HTTP_Response class. This centralizes HTTP operations and
-	  will be a start towards the creating of a testing framework.
-	* Updated: Backwards compatibility break: all require_once() statements
-	  are removed
-	  from all the files. It is now recommended to use autoloading of
-	  classes, or just including lib/Sabre.includes.php. This fix was made
-	  to allow easier integration into applications not using this standard
-	  inclusion model.
-	* Updated: Better in-file documentation.
-	* Updated: Sabre_DAV_Tree can now work with Sabre_DAV_LockManager.
-	* Updated: Fixes a shared-lock bug.
-	* Updated: Removed ?> from the bottom of each php file.
-	* Updated: Split up some operations from Sabre_DAV_Server to
-	  Sabre_HTTP_Response.

-	* Added: Phing build scripts
-	* Added: PEAR package
-	* Fixed: MOVE bug identified using finder.

-	* Added: Working PROPPATCH method (doesn't support custom properties yet)
-	* Added: Temporary filename handling system
