General:

• Add support for registration fallback. This is a page hosted on the server
  which allows a user to register for an account, regardless of what client
  they are using (e.g. mobile devices).
• Added new default push rules and made them configurable by clients:
  • Suppress all notice messages.
  • Notify when invited to a new room.
  • Notify for messages that don't match any rule.
  • Notify on incoming call.

Federation:

• Added per host server side rate-limiting of incoming federation requests.
• Added a /get_missing_events/ API to federation to reduce number of
  /events/ requests.

Configuration:

• Added configuration option to disable registration:
  disable_registration.
• Added configuration option to change soft limit of number of open file
  descriptors: soft_file_limit.
• Make tls_private_key_path optional when running with no_tls.

Application services:

• Application services can now poll on the CS API /events for their events,
  by providing their application service access_token.
• Added exclusive namespace support to application services API.
