⚠️ If you are upgrading from Mjolnir or a previous version of Draupnir, please not that the option protectAllJoinedRooms is not working. See #706.

Upgrade Steps

There are no manual upgrade steps, the new protections are automatically
enabled. The only thing you should note is that Draupnir now enables the new
roomStateBackingStore by default. This improves the startup time of Draupnir
considerably but if you need to disable it, see the config documentation
here.

There are also no upgrade steps to upgrading to v2.0.0 from Mjolnir.

Please see the
documentation
if you are installing Draupnir for the first time.

What's changed

TL;DR everything is so much better.

• Draupnir is now much less dependant on commands and will automatically send
  prompts to the management room. Prompts are sent for inviting Draupnir to
  protect rooms, watch policy lists, banning users, and unbanning users.

• Draupnir is much more responsive. Draupnir now does not need to request any
  data from the homeserver before applying new bans or to ban new users.

• Draupnir now uses a persistent revision system for room state, members,
  policies, and policy matches. By using revisions, Draupnir only has to process
  room state once in terms of simple deltas as room state is updated.

• Draupnir offers a
  room state backing store,
  allowing Draupnir to startup quickly, even when deployed at distance from the
  homeserver.

• Protection messages have been revised to present information more efficiently
  in the management room.

• A safe mode has been introduced that can be used to recover Draupnir in
  situations where watched lists or protected rooms become unjoinable.

• All commands now use the new command-oriented
  interface-manager.

• Protection settings have been reworked. The !draupnir protections show
  command now shows all configurable settings for a given protection and
  describes how they can be modified.

In addition to hundreds of other significant fixes, UX improvements, and other
changes that would be too detailed to list in this changelog. For a full list of
changes, please review the
