[friendica-addons.git] / dav / SabreDAV / ChangeLog

1.7.0-alpha (2012-??-??)
    * 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)
            - Sabre_VObject_Element_DateTime (now: .._Property_DateTime)
                - Sabre_VObject_Element_MultiDateTime (-> .._Property_MultiDateTime)
        * 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.
        * New feature: Support for caldav notifications!
        * 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.
        * 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.
        * 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: Workaround for 10.8 Mountain Lion vCards, as it needs \r line
          endings to parse them correctly.

1.6.4-stable (2012-??-??)
        * Fixed: Issue 220: Calendar-query filters may fail when filtering on
          alarms, if an overridden event has it's alarm removed.
        * Fixed: Compatibility for OS/X 10.8 iCal in the IMipHandler.
        * Fixed: Issue 222: beforeWriteContent shouldn't be called for lock
          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.

1.6.3-stable (2012-06-12)
        * Added: It's now possible to specify in Sabre_DAV_Client which type of
          authentication is to be used.
        * Fixed: Issue 206: Sabre_DAV_Client PUT requests are fixed.
        * Fixed: Issue 205: Parsing an iCalendar 0-second date interval.
        * Fixed: Issue 112: Stronger validation of iCalendar objects. Now making
          sure every iCalendar object only contains 1 component, and disallowing
          vcards, forcing every component to have a UID.
        * Fixed: Basic validation for vcards in the CardDAV plugin.
        * Fixed: Issue 213: Workaround for an Evolution bug, that prevented it
          from updating events.
        * Fixed: Issue 211: A time-limit query on a non-relative alarm trigger in
          a recurring event could result in an endless loop.
        * Fixed: All uri fields are now a maximum of 200 characters. The Bynari
          outlook plugin used much longer strings so this should improve
          compatibility.
        * Fixed: Added a workaround for a bug in KDE 4.8.2 contact syncing. See
          https://bugs.kde.org/show_bug.cgi?id=300047
        * Fixed: Issue 217: Sabre_DAV_Tree_FileSystem was pretty broken.

1.6.2-stable (2012-04-16)
        * Fixed: Sabre_VObject_Node::$parent should have been public.
        * Fixed: Recurrence rules of events are now taken into consideration when
          doing time-range queries on alarms.
        * Fixed: Added a workaround for the fact that php's DateInterval cannot
          parse weeks and days at the same time.
        * Added: Sabre_DAV_Server::$exposeVersion, allowing you to hide SabreDAV's
          version number from various outputs.
        * Fixed: DTSTART values would be incorrect when expanding events.
        * Fixed: DTSTART and DTEND would be incorrect for expansion of WEEKLY
          BYDAY recurrences.
        * Fixed: Issue 203: A problem with overridden events hitting the exact
          date and time of a subsequent event in the recurrence set.
        * Fixed: There was a problem with recurrence rules, for example the 5th
          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.
        * Fixed: Fixed a bug where an infinite loop could occur in the recurrence
          iterator if the recurrence was YEARLY, with a BYMONTH rule, and either
          BYDAY or BYMONTHDAY match the first day of the month.
        * Fixed: Events that are excluded using EXDATE are still counted in the
          COUNT= parameter in the RRULE property.
        * Added: Support for time-range filters on VALARM components.
        * Fixed: Correctly filtering all-day events.
        * Fixed: Sending back correct mimetypes from the browser plugin (thanks
          Jürgen).
        * Fixed: Issue 195: Sabre_CardDAV pear package had an incorrect dependency.
        * Fixed: Calendardata would be destroyed when performing a MOVE request.

1.6.0-stable (2012-02-22)
        * BC Break: Now requires PHP 5.3
        * BC Break: Any node that implemented Sabre_DAVACL_IACL must now also
          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.
        * Added: Possibility to let server send out invitation emails on behalf of
          CalDAV client, using Sabre_CalDAV_Schedule_IMip.
        * Changed: beforeCreateFile event now passes data argument by reference.
        * Changed: The 'propertyMap' property from Sabre_VObject_Reader, must now
          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.
        * Added: Sabre_VObject_FreeBusyGenerator to generate free-busy reports
          based on lists of events.
        * Added: Sabre_VObject_RecurrenceIterator to find all the dates and times
          for recurring events.
        * Fixed: Issue 97: Correctly handling RRULE for the calendar-query REPORT.
        * Fixed: Issue 154: Encoding of VObject parameters with no value was
          incorrect.
        * Added: Support for {DAV:}acl-restrictions property from RFC3744.
        * Added: The contentlength for calendar objects can now be supplied by a
          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.

1.5.7-stable (2012-02-19)
        * Fixed: VObject properties are now always encoded before components.
        * Fixed: Sabre_DAVACL had issues with multiple levels of privilege
          aggregration.
        * Changed: Added 'GuessContentType' plugin to fileserver.php example.
        * Fixed: The Browser plugin will now trigger the correct events when
          creating files.
        * Fixed: The ICSExportPlugin now considers ACL's.
        * Added: Made it optional to supply carddata from an Addressbook backend
          when requesting getCards. This can make some operations much faster, and
          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)

1.5.5-stable (2011-12-16)
        * Fixed: CalDAV time-range filter workaround for recurring events.
        * Fixed: Bug in Sabre_DAV_Locks_Backend_File that didn't allow multiple
          files to be locked at the same time.

1.5.4-stable (2011-10-28)
        * Fixed: GuessContentType plugin now supports mixed case file extensions.
        * Fixed: DATE-TIME encoding was wrong in VObject. (we used 'DATETIME').
        * Changed: Sending back HTTP 204 after a PUT request on an existing resource
          instead of HTTP 200. This should fix Evolution CardDAV client
          compatibility.
        * Fixed: Issue 95: Parsing X-LIC-LOCATION if it's available.
        * Added: All VObject elements now have a reference to their parent node.

1.5.3-stable (2011-09-28)
        * Fixed: Sabre_DAV_Collection was missing from the includes file.
        * Fixed: Issue 152. iOS 1.4.2 apparantly requires HTTP/1.1 200 OK to be in
          uppercase.
        * Fixed: Issue 153: Support for files with mixed newline styles in
          Sabre_VObject.
        * Fixed: Issue 159: Automatically converting any vcard and icalendardata
          to UTF-8.
        * Added: Sabre_DAV_SimpleFile class for easy static file creation.
        * Added: Issue 158: Support for the CARDDAV:supported-address-data
          property.

1.5.2-stable (2011-09-21)
        * Fixed: carddata and calendardata MySQL fields are now of type
          'mediumblob'. 'TEXT' was too small sometimes to hold all the data.
        * Fixed: {DAV:}supported-report-set is now correctly reporting the reports
          for IAddressBook.
        * Added: Sabre_VObject_Property::add() to add duplicate parameters to
          properties.
        * Added: Issue 151: Sabre_CalDAV_ICalendar and Sabre_CalDAV_ICalendarObject
          interfaces.
        * Fixed: Issue 140: Not returning 201 Created if an event cancelled the
          creation of a file.
        * Fixed: Issue 150: Faster URLUtil::encodePath() implementation.
        * Fixed: Issue 144: Browser plugin could interfere with
          TemporaryFileFilterPlugin if it was loaded first.
        * Added: It's not possible to specify more 'alternate uris' in principal
          backends.

          non-collections.
        * Fixed: addressbook-query is now correctly returned from the
          {DAV:}supported-report-set property.
        * Fixed: Issue 142: Bugs in groupwareserver.php example.
        * Fixed: Issue 139: Rejecting PUT requests with Content-Range.

1.5.0-stable (2011-08-12)
        * Added: CardDAV support.
        * 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
          removed in a future version. Use Sabre_DAV_SimpleCollection instead.
        * Fixed: Problem with overriding tablenames for the CalDAV backend.
        * Added: Clark-notation parser to XML utility.
        * Added: unset() support to VObject components.
        * Fixed: Refactored CalDAV property fetching to be faster and simpler.
        * Added: Central string-matcher for CalDAV and CardDAV plugins.

        * Fixed: VObject bug: wouldn't parse parameters if they weren't specified
          in uppercase.
        * Fixed: VObject bug: Parameters now behave more like Properties.
        * Fixed: VObject bug: Parameters with no value are now correctly parsed.
        * Changed: If calendars don't specify which components they allow, 'all'
          components are assumed (e.g.: VEVENT, VTODO, VJOURNAL).
        * Changed: Browser plugin now uses POST variable 'sabreAction' instead of
          'action' to reduce the chance of collisions.

1.4.4-stable (2011-07-07)
        * Fixed: Issue 131: Custom CalDAV backends could break in certain cases.
        * Added: The option to override the default tablename all PDO backends
          use. (Issue 60).
        * Fixed: Issue 124: 'File' authentication backend now takes realm into
          consideration.
        * Fixed: Sabre_DAV_Property_HrefList now properly deserializes. This
          allows users to update the {DAV:}group-member-set property.
        * Added: Helper functions for DateTime-values in Sabre_VObject package.
        * Added: VObject library can now automatically map iCalendar properties to
          custom classes.

1.4.3-stable (2011-04-25)
        * Fixed: Issue 123: Added workaround for Windows 7 UNLOCK bug.
        * Fixed: datatype of lastmodified field in mysql.calendars.sql. Please
          change the DATETIME field to an INT to ensure this field will work
          correctly.
        * Change: Sabre_DAV_Property_Principal is now renamed to
          Sabre_DAVACL_Property_Principal.
        * Added: API level support for ACL HTTP method.
        * Fixed: Bug in serializing {DAV:}acl property.
        * Added: deserializer for {DAV:}resourcetype property.
        * Added: deserializer for {DAV:}acl property.
        * Added: deserializer for {DAV:}principal property.

1.4.2-beta (2011-04-01)
        * Added: It's not possible to disable listing of nodes that are denied
          read access by ACL.
        * Fixed: Changed a few properties in CalDAV classes from private to
          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.

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.
        * Change: Slightly changed CalDAV Backend API's, to allow for heavy
          optimizations. This is non-bc breaking.

1.4.0-beta (2011-02-12)
        * 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.
        * Deprecated: The Sabre_CalDAV_ICalendarUtil class is now marked
          deprecated, and will be removed in a future version. Please use
          Sabre_VObject instead.
        * Removed: All principal-related functionality has been removed from the
          Sabre_DAV_Auth_Plugin, and moved to the Sabre_DAVACL_Plugin.
        * Added: VObject library, for easy vcard/icalendar parsing using a natural
          interface.
        * Added: Ability to automatically generate full .ics feeds off calendars.
          To use: Add the Sabre_CalDAV_ICSExportPlugin, and add ?export to your
          calendar url.
        * Added: Plugins can now specify a pluginname, for easy access using
          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.
        * 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 90: lockdiscovery property and LOCK response now include a
          {DAV}lockroot element.
        * Fixed: Issue 96: support for 'default' collation in CalDAV text-match
          filters.
        * Fixed: Issue 102: Ensuring that copy and move with identical source and
          destination uri's fails.
        * Fixed: Issue 105: Supporting MKCALENDAR with no body.
        * Fixed: Issue 109: Small fixes in Sabre_HTTP_Util.
        * Fixed: Issue 111: Properly catching the ownername in a lock (if it's a
          string)
        * Fixed: Sabre_DAV_ObjectTree::nodeExist always returned false for the
          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.
        * Removed: Sabre_DAV_PermissionDenied class. Use Sabre_DAV_Forbidden
          instead.
        * Removed: Sabre_DAV_IDirectory interface, use Sabre_DAV_ICollection
          instead.
        * Added: Browser plugin now uses {DAV:}displayname if this property is
          available.
        * Added: Cache layer in the ObjectTree.
        * Added: Tree classes now have a delete and getChildren method.
        * 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.
        * Fixed: Issue 67: Non-seekable stream support in ::put()/::get().
        * Fixed: Issue 65: Invalid dates are now ignored.
        * Updated: Refactoring in Sabre_CalDAV to make everything a bit more
          ledgable.

           Windows.
        * Fixed: Issue 86: Fixed Content-Range top-boundary from 'file size' to
          'file size'-1.

1.2.4 (2010-07-13)
        * Fixed: Issue 62: Guessing baseUrl fails when url contains a
          query-string.
        * Added: Apache configuration sample for CGI/FastCGI setups.

        * Fixed: Issue 56: Incorrect behaviour for If-None-Match headers and GET
          requests.

        * Fixed: Issue 38, Allowing custom filters to be added to
          TemporaryFileFilter.
        * Fixed: Issue 53, ETags in the If: header were always failing. This
          behaviour is now corrected.
        * Added: Apache Authentication backend, in case authentication through
          .htaccess is desired.
        * Updated: Small improvements to example files.

1.2.0 (2010-05-24)

        * Added: text/plain is used for .txt files in GuessContentType plugin.
        * Added: support for principal-property-search and
          principal-search-property-set reports.
        * Added: Issue 31: Hiding exception information by default. Can be turned
          on with the Sabre_DAV_Server::$debugExceptions property.

          debugging.
        * Fixed: Issue 36: Incorrect variable name, throwing error in some
          requests.
        * Fixed: Issue 37: Incorrect smultron regex in temporary filefilter.
        * Fixed: Issue 33: Converting ISO-8859-1 characters to UTF-8.

        * Added: More unittests.
        * Added: SabreDAV version to all error responses.
        * Added: URLUtil class for decoding urls.
        * Changed: Now using pear.sabredav.org pear channel.

        * Fixed: Issue 27: encoding entities in property responses.
        * Added: naturalselection script now allows the user to specify a 'minimum

        * Added: RFC5689 - Extended MKCOL support.
        * Fixed: Evolution support for CalDAV.
        * Fixed: PDO-locks backend was pretty much completely broken. This is
          100% unittested now.
        * Added: support for ctags.
        * Fixed: Comma's between HTTP methods in 'Allow' method.

        * Changed: Moved Sabre_DAV_Server::parseProps to
          Sabre_DAV_XMLUtil::parseProperties.

1.1.0-alpha (2010-03-01)
        * Note: This version is forked from version 1.0.5, so release dates may be
          out of order.
        * Added: CalDAV - RFC 4791
        * Removed: Sabre_PHP_Exception. PHP has a built-in ErrorException for
          this.
        * Added: PDO authentication backend.
        * Added: Example sql for auth, caldav, locks for sqlite.
        * Added: Sabre_DAV_Browser_GuessContentType plugin

          the case for for example {DAV:}principal.
        * Changed: The Href property class can now optionally create non-relative
          uri's.

          on with the Sabre_DAV_Server::$debugExceptions property.
        * Added: Moved autoload from lib/ to lib/Sabre/autoload.php. This is also
          the case in the upcoming 1.2.0, so it will improve future compatibility.

1.0.14-stable (2010-04-15)
        * Fixed: double namespace declaration in multistatus responses.

1.0.13-stable (2010-03-30)

        * Added: SabreDAV version to all error responses.
        * Added: URLUtil class for decoding urls.
        * Updated: Now using pear.sabredav.org pear channel.

1.0.11-stable (2010-03-23)
        * Non-public release. This release is identical to 1.0.10, but it is used
          to test releasing packages to pear.sabredav.org.

1.0.10-stable (2010-03-22)
        * Fixed: Issue 34: Invalid Lock-Token header response.
        * Added: Issue 35: Addign SabreDAV version to HTTP OPTIONS responses.

        * Fixed: Issue 21: typos causing errors
        * Fixed: Issue 23: Comma's between methods in Allow header.
        * Added: Sabre_DAV_ICollection interface, to aid in future compatibility.
        * Added: Sabre_DAV_Exception_Forbidden exception. This will replace
          Sabre_DAV_Exception_PermissionDenied in the future, and can already be
          used to ensure future compatibility.

1.0.7-stable (2010-02-24)
        * Fixed: Issue 19 regression for MS Office

1.0.6-stable (2010-02-23)
        * Fixed: Issue 19: HEAD requests on Collections

1.0.5-stable (2010-01-22)
        * Fixed: Fatal error when a malformed url was used for unlocking, in
          conjuction with Sabre.autoload.php due to a incorrect filename.
        * Fixed: Improved unittests and build system

1.0.4-stable (2010-01-11)
        * Fixed: needed 2 different releases. One for googlecode and one for
          pearfarm. This is to retain the old method to install SabreDAV until
          pearfarm becomes the standard installation method.

1.0.3-stable (2010-01-11)
        * Added: RFC4709 support (davmount)
        * Added: 6 unittests
        * Added: naturalselection. A tool to keep cache directories below a
          specified theshold.
        * Changed: Now using pearfarm.org channel server.

1.0.1-stable (2009-12-22)
        * Fixed: Issue 15: typos in examples
        * Fixed: Minor pear installation issues

1.0.0-stable (2009-11-02)
        * Added: SimpleDirectory class. This class allows creating static
          directory structures with ease.
        * 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.

          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.

        * Fixed: Locking bug, which became prevalent on Windows Vista.
        * Fixed: Netdrive support

        * 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: 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.

        * 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

0.3-alpha (2008-06-29)
        * Fully working in MS Windows clients.
        * 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.

        * Somewhat working in Windows clients
        * Added: Working PROPPATCH method (doesn't support custom properties yet)
        * Added: Temporary filename handling system

        * First release!
        * Passes litmus: basic, http and copymove test.
