+## 2.0.0 (2019-06-06)
+
+### Codebase
+
+- Ported to Python 3
+
+### Core
+
+- Improved Logging
+- Removed the AutoAdd feature on the core. It's now handled with the AutoAdd
+  plugin, which is also shipped with Deluge, and it does a better job and
+  now, it even supports multiple users perfectly.
+- Authentication/Permission exceptions are now sent to clients and recreated
+  there to allow acting upon them.
+- Updated SSL/TLS Protocol parameters for better security.
+- Make the distinction between adding to the session new unmanaged torrents
+  and torrents loaded from state. This will break backwards compatibility.
+- Pass a copy of an event instead of passing the event arguments to the
+  event handlers. This will break backwards compatibility.
+- Allow changing ownership of torrents.
+- File modifications on the auth file are now detected and when they happen,
+  the file is reloaded. Upon finding an old auth file with an old format, an
+  upgrade to the new format is made, file saved, and reloaded.
+- Authentication no longer requires a username/password. If one or both of
+  these is missing, an authentication error will be sent to the client
+  which should then ask the username/password to the user.
+- Implemented sequential downloads.
+- Provide information about a torrent's pieces states
+- Add Option To Specify Outgoing Connection Interface.
+- Fix potential for host_id collision when creating hostlist entries.
+
+### Gtk UI
+
+- Ported to GTK3 (3rd-party plugins will need updated).
+- Allow changing ownership of torrents.
+- Host entries in the Connection Manager UI are now editable.
+- Implemented sequential downloads UI handling.
+- Add optional pieces bar instead of a regular progress bar in torrent status tab.
+- Make torrent opening compatible with all Unicode paths.
+- Fix magnet association button on Windows.
+- Add keyboard shortcuts for changing queue position:
+  - Up: `Ctrl+Alt+Up`
+  - Down: `Ctrl+Alt+Down`
+  - Top: `Ctrl+Alt+Shift+Up`
+  - Bottom: `Ctrl+Alt+Shift+Down`
+
+### Web UI
+
+- Server (deluge-web) now daemonizes by default, use '-d' or '--do-not-daemonize' to disable.
+- Fixed the '--base' option to work for regular use, not just with reverse proxies.
+
+### Blocklist Plugin
+
+- Implemented whitelist support to both core and GTK UI.
+- Implemented IP filter cleaning before each update. Restarting the deluge
+  daemon is no longer needed.
+- If "check_after_days" is 0(zero), the timer is not started anymore. It
+  would keep updating one call after the other. If the value changed, the
+  timer is now stopped and restarted using the new value.

-FAQ
-==========================
-
-How to start the various user-interfaces
-
-    Gtk:
-        deluge --ui gtk
-    Console:
-        deluge --ui null
-    Web:
-        deluge --ui web
-        Go to http://localhost:8112/ default-password = "deluge"
-
-I started "deluge" but i don't see the gtk-ui
-
-    The deluge command remembers the last interface it started. Be explicit and type one of the full "deluge -u <interface>" commands listed above.
-
-Why is deluge still listed in my system tray even after I close it ?
-
-    You closed the gtk user-interface but you did not close the daemon. Choose "Quit & Shutdown Daemon" to close both Daemon and gtk-ui.
-
-How do I start the daemon ?
-
-    deluged
-
-How do I start the daemon with logging to console ?
-
-    deluged -d
-
-I can't connect to the daemon from another machine
-
-    * Configure the daemon to allow remote connections
-    * Restart the daemon.
-
-    Note: do not do this on a public ip , use the webui for unsecure networks.
-
-I upgraded from 0.5 and plugin x is missing
-
-    1.0 is a rewrite, all old 0.5 plugins have to be rewritten.

-"""Simple XML-RPC Server.
-
-This module can be used to create simple XML-RPC servers
-by creating a server and either installing functions, a
-class instance, or by extending the SimpleXMLRPCServer
-class.
-
-It can also be used to handle XML-RPC requests in a CGI
-environment using CGIXMLRPCRequestHandler.
-
-A list of possible usage patterns follows:
-
-1. Install functions:
-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_function(pow)
-server.register_function(lambda x,y: x+y, 'add')
-server.serve_forever()
-
-2. Install an instance:
-
-class MyFuncs:
-    def __init__(self):
-        # make all of the string functions available through
-        # string.func_name
-        import string
-        self.string = string
-    def _listMethods(self):
-        # implement this method so that system.listMethods
-        # knows to advertise the strings methods
-        return list_public_methods(self) + \
-                ['string.' + method for method in list_public_methods(self.string)]
-    def pow(self, x, y): return pow(x, y)
-    def add(self, x, y) : return x + y
-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_introspection_functions()
-server.register_instance(MyFuncs())
-server.serve_forever()
-
-3. Install an instance with custom dispatch method:
-
-class Math:
-    def _listMethods(self):
-        # this method must be present for system.listMethods
-        # to work
-        return ['add', 'pow']
-    def _methodHelp(self, method):
-        # this method must be present for system.methodHelp
-        # to work
-        if method == 'add':
-            return "add(2,3) => 5"
-        elif method == 'pow':
-            return "pow(x, y[, z]) => number"
-        else:
-            # By convention, return empty
-            # string if no help is available
-            return ""
-    def _dispatch(self, method, params):
-        if method == 'pow':
-            return pow(*params)
-        elif method == 'add':
-            return params[0] + params[1]
-        else:
-            raise 'bad method'
-
-server = SimpleXMLRPCServer(("localhost", 8000))
-server.register_introspection_functions()
-server.register_instance(Math())
-server.serve_forever()
-
-4. Subclass SimpleXMLRPCServer:
-
-class MathServer(SimpleXMLRPCServer):
-    def _dispatch(self, method, params):
-        try:
-            # We are forcing the 'export_' prefix on methods that are
-            # callable through XML-RPC to prevent potential security
-            # problems
-            func = getattr(self, 'export_' + method)
-        except AttributeError:
-            raise Exception('method "%s" is not supported' % method)
-        else:
-            return func(*params)
-
-    def export_add(self, x, y):
-        return x + y
-
-server = MathServer(("localhost", 8000))
-server.serve_forever()
-
-5. CGI script:
-
-server = CGIXMLRPCRequestHandler()
-server.register_function(pow)
-server.handle_request()

 Deluge Config Module
+
+This module is used for loading and saving of configuration files.. or anything
+really.
+
+The format of the config file is two json encoded dicts:
+
+<version dict>
+<content dict>
+
+The version dict contains two keys: file and format.  The format version is
+controlled by the Config class.  It should only be changed when anything below
+it is changed directly by the Config class.  An example of this would be if we
+changed the serializer for the content to something different.
+
+The config file version is changed by the 'owner' of the config file.  This is
+to signify that there is a change in the naming of some config keys or something
+similar along those lines.
+
+The content is simply the dict to be saved and will be serialized before being
+written.
+
+Converting
+
+Since the format of the config could change, there needs to be a way to have
+the Config object convert to newer formats.  To do this, you will need to
+register conversion functions for various versions of the config file. Note that
+this can only be done for the 'config file version' and not for the 'format'
+version as this will be done internally.
