	  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

	  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

	  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)

	* 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!)

1.6.5-stable (2012-10-04)
	* Fixed: Workaround for line-ending bug OS X 10.8 addressbook has.
	* Added: Ability to allow users to set SSL certificates for the Client
	  class. (Thanks schiesbn!).

	  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
	  calendar-query REPORT and free-busy calculations.

	  https://bugs.kde.org/show_bug.cgi?id=300047
	* Fixed: Issue 217: Sabre_DAV_Tree_FileSystem was pretty broken.

	  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.

	  iterator if the recurrence was YEARLY, with a BYMONTH rule, and either
	  BYDAY or BYMONTHDAY match the first day of the month.

	  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.
	* Added: Support for FREEBUSY reports!
	* Added: Support for creating principals with admin-level privileges.

	  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.
	* Added: Sabre_VObject_Component_VEvent, Sabre_VObject_Component_VJournal,
	  Sabre_VObject_Component_VTodo and Sabre_VObject_Component_VCalendar.
	* 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)
	* Fixed: Issue with parsing timezone identifiers that were surrounded by
	  quotes. (Fixes emClient compatibility).

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

	  creating files.
	* Fixed: The ICSExportPlugin now considers ACL's.

	  could result in much lower memory use.
	* Fixed: Issue 187: Sabre_DAV_UUIDUtil was missing from includes file.
	* Fixed: Issue 191: beforeUnlock was triggered twice.

1.5.6-stable (2012-01-07)

	* Fixed: GuessContentType plugin now supports mixed case file extensions.
	* Fixed: DATE-TIME encoding was wrong in VObject. (we used 'DATETIME').

	  property.

1.5.2-stable (2011-09-21)
	* Fixed: carddata and calendardata MySQL fields are now of type

	  for IAddressBook.
	* Added: Sabre_VObject_Property::add() to add duplicate parameters to
	  properties.

	* Added: An experimental WebDAV client.
	* 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 future version. Use Sabre_DAV_Collection instead.
	* Deprecated: Sabre_DAV_SimpleDirectory is now deprecated and will be

	  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
	  cases where there were similar named locked files in a directory.

	* 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.
	* BC break: In order to fix Issue 99, a new argument had to be added to

	  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.

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

	  Sabre_DAV_Server::getPlugin().
	* Added: beforeGetProperties event.
	* 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.

	  hardcoded to 'principals/[user]'.
	* Added: getSupportedReportSet method in ServerPlugin class. This allows

	  root node.
	* Added: Global way to easily supply new resourcetypes for certain node
	  classes.
	* 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 (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.

	  'file size'-1.

	* Fixed: Improved unittests and build system

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

	  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.

	  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: The Auth backend got a getUsers method
	* Added: Sabre_DAV_FSExt_Directory now returns quota info

	  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.
	* Fixed: examples are now actually included in the pear package.

0.4-alpha (2008-11-05)
	* Passes all litmus tests!
	* Added: more examples
	* Added: Custom property support
	* Added: Shared lock support
	* Added: Depth support to locks
	* Added: Locking on unmapped urls (non-existent nodes)
	* Fixed: Advertising as WebDAV class 3 support

	* Added: temporary file filter: support for smultron files.
	* Added: Phing build scripts
	* Added: PEAR package
	* Fixed: MOVE bug identified using finder.
	* Fixed: Using gzuncompress instead of gzdecode in the temporary file
	  filter. This seems more common.

0.2-alpha (2008-05-27)
	* Somewhat working in Windows clients
	* Added: Working PROPPATCH method (doesn't support custom properties yet)
	* Added: Temporary filename handling system
	* Added: Sabre_DAV_IQuota to return quota information
	* Added: PROPFIND now reads the request body and only supplies the
	  requested properties

	* First release!
	* Passes litmus: basic, http and copymove test.
	* Fully working in Finder and DavFSv2
