-3.2.0-alpha1 (2016-05-09)
--------------------------
-
-* Database changes for CalDAV. If you are using the CalDAV PDO backends, you
-  must migrate. Run `./bin/migrateto32.php` for more info.
-* Support for WebDAV Resource Sharing, an upcoming standard.
-* Added support for sharing in the CalDAV PDO backend! Users can now invite
-  others to their calendar and give them read/read-write access!
-* #397: Support for PSR-3. You can now log exceptions with your favourite
-  psr3-compatible logging tool.
-* #825: Actual proper, tested support for PostgreSQL. We require version 9.5.
-* Removed database migration script for sabre/dav 1.7. To update from that
-  version you now first need to update to sabre/dav 3.1.
-* Removed deprecated function: `Sabre\DAV\Auth\Plugin::getCurrentUser()`.
-* #774: Fixes for getting free disk space on Windows.
-* #803: Major changes in the sharing API. If you were using an old sabre/dav
-  sharing api, head to the website for more detailed migration notes.
-* #657: Support for optional auth using `{DAV:}unauthorized` and `{DAV:}all`
-  privileges. This allows you to assign a privilege to a resource, allowing
-  non-authenticated users to access it. For instance, this could allow you
-  to create a public read-only collection.
-* #812 #814: ICS/VCF exporter now includes a more useful filename in its
-  `Content-Disposition` header. (@Xenopathic).
-* #801: BC break: If you were using the `Href` object before, it's behavior
-  now changed a bit, and `LocalHref` was added to replace the old, default
-  behavior of `Href`. See the migration doc for more info.
-* Removed `Sabre\DAVACL\Plugin::$allowAccessToNodesWithoutACL` setting.
-  Instead, you can provide a set of default ACL rules with
-  `Sabre\DAVACL\Plugin::setDefaultAcl()`.
-* Introduced `Sabre\DAVACL\ACLTrait` which contains a default implementation
-  of `Sabre\DAV\IACL` with some sane defaults. We're using this trait all over
-  the place now, reducing the amount of boilerplate.
-* Plugins can now control the "Supported Privilege Set".
-* Added Sharing, ICSExport and VCFExport plugins to `groupwareserver.php`
-  example.
-* The `{DAV:}all` privilege is now no longer abstract, so it can be assigned
-  directly. We're using the `{DAV:}all` privilege now in a lot of cases where
-  we before assigned both `{DAV:}read` and `{DAV:}write`.
-* Resources that are not collections no longer support the `{DAV:}bind` and
-  `{DAV:}unbind` privileges.
-* Corrected the CalDAV-scheduling related privileges.
-* Doing an `UNLOCK` no longer requires the `{DAV:}write-content` privilege.
-* Added a new `getPrincipalByUri` plugin event. Allowing plugins to request
-  quickly where a principal lives on a server.
-* Renamed `phpunit.xml` to `phpunit.xml.dist` to make local modifications easy.
-* Functionality from `IShareableCalendar` is merged into `ISharedCalendar`.
-* #751: Fixed XML responses from failing `MKCOL` requests.
-* #600: Support for `principal-match` ACL `REPORT`.
-* #599: Support for `acl-principal-prop-set` ACL `REPORT`.
-* #798: Added an index on `firstoccurence` field in MySQL CalDAV backend. This
-  should speed up common calendar-query requests.
-* #759: DAV\Client is now able to actually correctly resolve relative urls.
-* #671: We are no longer checking the `read-free-busy` privilege on individual
-  calendars during freebusy operations in the scheduling plugin. Instead, we
-  check the `schedule-query-freebusy` privilege on the target users' inbox,
-  which validates access for the entire account, per the spec.
-* The zip release ships with [sabre/vobject 4.1.0][vobj],
-  [sabre/http 4.2.1][http], [sabre/event 3.0.0][evnt],

-------------------

-* #721: Events are now handled in the correct order for `COPY` requests.

--------------------------
-

-  list. This should fix iOS attendee autocomplete support.
-* Changed: Moved all 'notifications' functionality from `Sabre\CalDAV\Plugin`
-  to a new plugin: `Sabre\CalDAV\Notifications\Plugin`. If you want to use
-  notifications-related functionality, just add this plugin.

-  now receive both vCard 3.0 and 4.0.
-* Added: #444. Collections can now opt-in to support high-speed `MOVE`.
-* Changed: PropertyStorage backends now have a `move` method.

-  PROPFIND request is being done. (@aklomp)
-* Changed: Now return HTTP errors when an addressbook-query REPORT is done
-  on a uri that's not a vcard. This should help with debugging this common
-  mistake.

-  instead of 501, as per RFC7231.
-* Added: Browser plugin can now display the contents of the

-------------------
-

-  so this makes it slightly easier to write code that works in both branches.
-* #497: Making sure we're initializing the sync-token field with a value after
-  migration.
-* The zip release ships with [sabre/vobject 3.3.4][vobj],

-  [sabre/http 2.0.3][http], and [sabre/event 1.0.0][evnt].

-  document][mi20] for more information. This allows for creation of a generic
-  property storage, and other property-related functionality that was not
-  possible before.
-* BC Break: Removed `propertyUpdate`, `beforeGetProperties` and
-  `afterGetProperties` events.
-* Fixed: #413: Memory optimizations for the CardDAV PDO backend.
-* Updated: Brand new browser plugin with more debugging features and a design

-* Making it easier for implementors to override how the CardDAV addressbook
-  home is located.

-* Fixed: Issues #430, #431, #433: Locks plugin didn't not properly release

-* Fixed: #175. Returning ETag header upon a failed `If-Match` or
-  `If-None-Match` check.

-  Sabre_DAV_PartialUpdate_IFile interface is now deprecated and will be
-  removed in a future version.
-* Added: `Sabre\DAV\Exception\LengthRequired`.

--------------------------
-
-* The zip release ships with sabre/vobject 3.1.3, sabre/http 2.0.0alpha5, and
-  sabre/event 1.0.0.
-* BC Break: The CardDAV and CalDAV BackendInterface each have a new method:
-  getMultipleCards and getMultipleCalendarObjects. The Abstract and PDO backends
-  have default implementations, but if you implement that interface directly,
-  this method is now required.
-* BC Break: XML property classes now receive an extra argument in their
-  unserialize method ($propertyMap). This allows for recursively parsing
-  properties, if needed.
-* BC Break: Now using sabre/event for event emitting/subscription. For plugin
-  authors this means Server::subscribeEvent is now Server::on, and
-  Server::broadcastEvent is now Server::emit.

-  CalDAV.
-* Added: BasicCallback authenticaton backend, for creating simple authentication
-  systems without having to define any classes.
-* Added: A $transactionType property on the server class. This can be used for
-  logging and performance measuring purposes.
-* Fixed: If event handlers modify the request body from a PUT request, an ETag
-  is no longer sent back.
-* Added: Sabre\DAV\IMultiGet to optimize requests that retrieve information
-  about lists of resources.
-* Added: MultiGet support to default CalDAV and CardDAV backends, speeding up
-  the multiget and sync reports quite a bit!
-* Added: ICSExportPlugin can now generate jCal, filter on time-ranges and expand
-  recurrences.
-* Fixed: Read-only access to calendars still allows the sharee to modify basic
-  calendar properties, such as the displayname and color.
-* Changed: The default supportedPrivilegeSet has changed. Most privileges are no
-  longer marked as abstract.
-* Changed: More elegant ACL management for CalendarObject and Card nodes.
-* Added: Browser plugin now marks a carddav directory as type Directory, and a
-  shared calendar as 'Shared'.
-* Added: When debugExceptions is turned on, all previous exceptions are also
-  traversed.
-* Removed: Got rid of the Version classes for CalDAV, CardDAV, HTTP, and DAVACL.
-  Now that there's no separate packages anymore, this makes a bit more sense.
-* Added: Generalized the multistatus response parser a bit more, for better
-  re-use.
-* Added: Sabre\DAV\Client now has support for complex properties for PROPPATCH.
-  (Issue #299).
-* Added: Sabre\DAV\Client has support for gzip and deflate encoding.

-  cards.
-* Added: The ability for plugins to validate custom tokens in If: headers.

-  system.
-* Added: Checking preconditions for MOVE, COPY, DELETE and PROPPATCH methods.
-* Added: has() method on DAV\Property\SupportedReportSet.
-* Added: If header now gets checked (with ETag) all the time. Before the dealing
-  with the If-header was a responsibility of the Locking plugin.
-* Fixed: Outbox access for delegates.
-* Added: Issue 333: It's now possible to override the calendar-home in the
-  CalDAV plugin.
-* Added: A negotiateContentType to HTTP\Request. A convenience method.
-* Fixed: Issue 349: Denying copying or moving a resource into it's own subtree.
-* Fixed: SabreDAV catches every exception again.
-* Added: Issue #358, adding a component=vevent parameter to the content-types
-  for calendar objects, if the caldav backend provides this info.

-------------------
-
-* The zip release ships with sabre/vobject 2.0.6.

-* 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'.

-  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 (2012-10-07)
-------------------
-
-* Fixed: include path problem in the migration script.
-
-
-1.7.0 (2012-10-06)
-------------------
-

-  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

-* 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

-  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 (2013-01-19)
-------------------

-* 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

-
-1.6.1 (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

-  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: Calendardata would be destroyed when performing a MOVE request.
-
-

-  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.

-* 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.

-  codes.
-* Added: Some mysql unique constraints to example files.
-* Fixed: Correctly formatting HTTP dates.

-  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.

-  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.

-  lib/Sabre/autoload.php.
-* Deprecated: Sabre_DAV_Directory is now deprecated and will be removed in a

-  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

-* Fixed: Issue 118: Lock tokens in If headers without a uri should be treated as
-  the request uri, not 'all relevant uri's.

------------------------
-

-* 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.

-  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

-  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.

-  size'-1.
-

-1.0.0 (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()

-  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

-* 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
-

-----------------------
-
-* Changed: Major refactoring, removed most of the logic from the Tree objects.

-  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

-* 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.

-  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

-  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.

-* 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
-
-
-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.
-
-
-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
-
-
-0.1-alpha (2008-04-04)
-----------------------
-
-* First release!
-* Passes litmus: basic, http and copymove test.
-* Fully working in Finder and DavFS2.
-
-Project started: 2007-12-13

-Contributing to sabre projects
-==============================
-
-Want to contribute to sabre/dav? Here are some guidelines to ensure your patch
-gets accepted.
-
-
-Building a new feature? Contact us first
-----------------------------------------
-
-We may not want to accept every feature that comes our way. Sometimes
-features are out of scope for our projects.
-
-We don't want to waste your time, so by having a quick chat with us first,
-you may find out quickly if the feature makes sense to us, and we can give
-some tips on how to best build the feature.
-
-If we don't accept the feature, it could be for a number of reasons. For
-instance, we've rejected features in the past because we felt uncomfortable
-assuming responsibility for maintaining the feature.
-
-In those cases, it's often possible to keep the feature separate from the
-sabre projects. sabre/dav for instance has a plugin system, and there's no
-reason the feature can't live in a project you own.
-
-In that case, definitely let us know about your plugin as well, so we can
-feature it on [sabre.io][4].
-
-We are often on [IRC][5], in the #sabredav channel on freenode. If there's
-no one there, post a message on the [mailing list][6].
-
-
-Coding standards
-----------------
-
-sabre projects follow:
-
-1. [PSR-1][1]
-2. [PSR-4][2]
-
-sabre projects don't follow [PSR-2][3].
-
-In addition to that, here's a list of basic rules:
-
-1. PHP 5.4 array syntax must be used every where. This means you use `[` and
-   `]` instead of `array(` and `)`.
-2. Use PHP namespaces everywhere.
-3. Use 4 spaces for indentation.
-4. Try to keep your lines under 80 characters. This is not a hard rule, as
-   there are many places in the source where it felt more sensibile to not
-   do so. In particular, function declarations are never split over multiple
-   lines.
-5. Opening braces (`{`) are _always_ on the same line as the `class`, `if`,
-   `function`, etc. they belong to.
-6. `public` must be omitted from method declarations. It must also be omitted
-   for static properties.
-7. All files should use unix-line endings (`\n`).
-8. Files must omit the closing php tag (`?>`).
-9. `true`, `false` and `null` are always lower-case.
-10. Constants are always upper-case.
-11. Any of the rules stated before may be broken where this is the pragmatic
-    thing to do.
-
-
-Unit test requirements
-----------------------
-
-Any new feature or change requires unittests. We use [PHPUnit][7] for all our
-tests.
-
-Adding unittests will greatly increase the likelyhood of us quickly accepting
-your pull request. If unittests are not included though for whatever reason,
-we'd still _love_ your pull request.
-
-We may have to write the tests ourselves, which can increase the time it takes
-to accept the patch, but we'd still really like your contribution!
-
-To run the testsuite jump into the directory `cd tests` and trigger `phpunit`.
-Make sure you did a `composer install` beforehand.
-
-Release process
----------------
-
-Generally, these are the steps taken to do releases.
-
-1. Update the changelog. Every repo will have a `CHANGELOG.md` file. This file
-   should have a new version, and contain all the changes since the last
-   release. I generally run a `git diff` to figure out if I missed any changes.
-   This file should also have the current date.
-2. If there were BC breaks, this usually now means a major version bump.
-3. Ensure that `lib/Version.php` or `lib/DAV/Version.php` also matches this
-   version number.
-4. Tag the release (Example `git tag 3.0.1` and push the tag (`git push --tags`).
-5. (only for the sabre/dav project), create a zip distribution. Run
-   `php bin/build.php`.
-6. For the relevant project, go to github and click the 'releases' tab. On this
-   tab I create the release with the relevant version. I also set the
-   description of the release to the same information of the changelog. In the
-   case of the `sabre/dav` project I also upload the zip distribution here.
-7. Write a blog post on sabre.io. This also automatically updates twitter.

-
-* Fixed: Issue #55. \r must be stripped from property values.
-* Fixed: Issue #65. Putting quotes around parameter values that contain a colon.
-
-
-2.1.2 (2013-08-02)
-------------------
-
-* Fixed: Issue #53. A regression in RecurrenceIterator.
-
-
-2.1.1 (2013-07-27)
-------------------
-
-* Fixed: Issue #50. RecurrenceIterator gives incorrect result when exception
-  events are out of order in the iCalendar file.
-* Fixed: Issue #48. Overridden events in the recurrence iterator that were past
-  the UNTIL date were ignored.
-
-
-2.1.0 (2013-06-17)
-------------------
-
-* This version is fully backwards compatible with 2.0.\*. However, it contains a
-  few new API's that mimic the VObject 3 API. This allows it to be used a
-  'bridge' version. Specifically, this new version exists so SabreDAV 1.7 and
-  1.8 can run with both the 2 and 3 versions of this library.
-* Added: Property\DateTime::hasTime().
-* Added: Property\MultiDateTime::hasTime().
-* Added: Property::getValue().
-* Added: Document class.
-* Added: Document::createComponent and Document::createProperty.
-* Added: Parameter::getValue().
-
-
-2.0.7 (2013-03-05)
-------------------
-
-* Fixed: Microsoft re-uses their magic numbers for different timezones,
-  specifically id 2 for both Sarajevo and Lisbon). A workaround was added to
-  deal with this.
-
-
-2.0.6 (2013-02-17)
-------------------
-
-* Fixed: The reader now properly parses parameters without a value.
-
-
-2.0.5 (2012-11-05)
-------------------
-
-* Fixed: The FreeBusyGenerator is now properly using the factory methods for
-  creation of components and properties.
-
-
-2.0.4 (2012-11-02)
-------------------
-
-* Added: Known Lotus Notes / Domino timezone id's.
-
-
-2.0.3 (2012-10-29)
-------------------
-
-* Added: Support for 'GMT+????' format in TZID's.
-* Added: Support for formats like SystemV/EST5EDT in TZID's.
-* Fixed: RecurrenceIterator now repairs recurrence rules where UNTIL < DTSTART.
-* Added: Support for BYHOUR in FREQ=DAILY (@hollodk).
-* Added: Support for BYHOUR and BYDAY in FREQ=WEEKLY.
-
-
-2.0.2 (2012-10-06)
-------------------
-
-* Added: includes.php file, to load the entire library in one go.
-* Fixed: A problem with determining alarm triggers for TODO's.
-
-
-2.0.1 (2012-09-22)
-------------------
-
-* Removed: Element class. It wasn't used.
-* Added: Basic validation and repair methods for broken input data.
-* Fixed: RecurrenceIterator could infinitely loop when an INTERVAL of 0 was
-  specified.
-* Added: A cli script that can validate and automatically repair vcards and
-  iCalendar objects.
-* Added: A new 'Compound' property, that can automatically split up parts for
-  properties such as N, ADR, ORG and CATEGORIES.
-* Added: Splitter classes, that can split up large objects (such as exports)
-  into individual objects (thanks @DominikTo and @armin-hackmann).
-* Added: VFREEBUSY component, which allows easily checking wether timeslots are
-  available.
-* Added: The Reader class now has a 'FORGIVING' option, which allows it to parse
-  properties with incorrect characters in the name (at this time, it just allows
-  underscores).
-* Added: Also added the 'IGNORE_INVALID_LINES' option, to completely disregard
-  any invalid lines.
-* Fixed: A bug in Windows timezone-id mappings for times created in Greenlands
-  timezone (sorry Greenlanders! I do care!).
-* Fixed: DTEND was not generated correctly for VFREEBUSY reports.
-* Fixed: Parser is at least 25% faster with real-world data.
-
-
-2.0.0 (2012-08-08)
-------------------
-
-* VObject is now a separate project from SabreDAV. See the SabreDAV changelog
-  for version information before 2.0.
-* New: VObject library now uses PHP 5.3 namespaces.
-* New: It's possible to specify lists of parameters when constructing
-  properties.
-* New: made it easier to construct the FreeBusyGenerator.
