v2.3.0-beta.1

[v2.3.0-beta.1]

Added

• A new protection has been added to automatically suspend resident users
  matching policies from Draupnir's watched lists
  (HomeserverUserPolicyProtection). If the policies match
  automaticallyRedactForReasons then the management will also be prompted for
  a purging deactivation to remove the user's messages.

• !draupnir deactivate <user id> now prompts for confirmation and has a
  --purge-messages option, which will restrict the user's account while all of
  their messages are redacted.

• !draupnir unrestrict <user id> command that will unsuspend / unshadowban the
  user's account.

• !draupnir suspend <user id> command that uses the synapse admin API to
  suspend users.

Changed

• The Redaction Synchronisation Protection has been improved in a few ways:
  • Invitations in protected rooms will be rejected as part of the redaction
    process when they are sent from users being redacted (e.g. as a brigading
    tactic).
  • User redaction will now be triggered on bans and the reason will be scanned
    for automaticallyRedactForReasons from Draupnir's config.

Fixed

• The Draupnir bot itself is now excluded from the MentionLimitProtection thanks
  to @nexy7574 in #815.

• MessageIsMediaProtection now correctly checks for noop thanks to @FSG-Cat in
  #807.

• Redactions are now ignored in BasicFloodingProtection thanks to @nexy7574 in
  #805

• @FSG-Cat has changed some more mentions of Mjolnir to Draupnir in
  #796.
