v1.6.4

This is a bugfix release.

ChangeLog

Bot

• Bugfix: In Mjölnir-for-all, make sure that config.bot.displayName is always set, by @Yoric in 9693149

v1.6.3

ChangeLog

Bot

• Bugfix: !mjolnir config get was broken, should now be fixed by @jesopo in 5824539.
• Feature: Support for decentralized abuse report (MSC3215). Use command !mjolnir rooms setup <room alias/ID> reporting to setup a room so that users can decide to send abuse reports to moderators (who can read the offending messages) instead of homeserver administrators (who typically cannot) by @Yoric in fa5fbee, 5b509a2. Sending an abuse report this way currently requires Element Web Develop with Labs feature report_to_moderator.
• Feature: Mjölnir-for-all bot now has a nicer name and is easier to invite by @Yoric in d83127e.

Hosting

• Feature: Early support for OpenMetrics/Prometheus. If you are hosting your Mjölnir, this will let you monitor e.g. CPU usage, memory usage, number of Matrix errors, ... Additional probes may be added in the future. Off by default. By @Yoric in c3cb22b

Security

• Bumping up dependency json5 to 1.0.2 by @dependabot in 1451ac9

v1.6.2

Changelog

Year

• We are now in 2023. Happy New Year to all!

Bot

• Change of behavior The bot can now start even if it doesn't manage to resolve some policy rooms. Note that this situation is not ideal, because a broken policy room means that your protections are most likely broken, but at least users are now able to use Mjölnir to fix that list by @Yoric in 433ff7e.
• Change of behavior Setting autojoinOnlyIfManager is now true by default by @Gnuxie in 1d3da94.
• Performance improvement Changing the policy sync algorithm means that we need fewer communications with the homeserver whenever there are policy list changes by @Gnuxie in 704bb66.

Monitoring

• Mjölnir now supports sending events and alerts to a Sentry server by @Yoric in 2915757.

Dependencies

• Bump express 4.17.3 in dafbd20

v1.6.1

Changelog

Bot:

• Change of behaviour: Mjolnir now supports specifying the config file with the argument --mjolnir-config. It is highly recommended that you do this as opposed to relying on the environment variable NODE_ENV. The documentation for running with docker and from source have been updated accordingly.
• Change of behaviour: If you had run latest since v1.5.0 or v1.6.0, briefly mjolnir would have loaded default.yaml if NODE_ENV was unset, whereas previously it would have loaded development.yaml. This led to highly confusing behaviour as the documentation for running from source had instructed users to create development.yaml without setting NODE_ENV=development while running mjolnir, which was how mjolnir understood to load development.yaml in all previous versions. Silently loading the default was an undocumented new behaviour that has now been removed.
• Fixed a bug where if config.protectAllJoinedRooms was enabled mjolnir would temporarily start protecting all watched policy lists at startup. by @Gnuxie in #431. Thanks to @cremesk for reporting.

v1.6.0

Changelog

Bot:

Changes of behaviour:

• Use stable prefixes for policy recommendations (m.ban instead of org.matrix.mjolnir.ban) by @deepbluev7 in #329
• Always echo policy list changes. List changes are now always enabled, whereas before they where only shown with config.verboseLogging. Mjolnir now no longer hides changes made by the same mjolnir account, providing the user with feedback for changes they have made to policy lists after using the ban/unban commands. by @Gnuxie in #401
• Replaced acceptInvitesFromGroup with acceptInvitesFromSpace. by @Gnuxie in #338
• Policy lists created by mjolnir will now be done so with support for MSC3784. by @Gnuxie in #386

Everything else:

• Fix the WordList protection which was matching every message. by @Gnuxie in #427
• Rework the banning and unbanning of entities in PolicyLists by @Gnuxie in #345:
  • Unbanning no longer searches for rules by state_key but by entity.
  • Users with longer mxids can now be banned.
  • Mjolnir no longer waits for the next client sync before applying server ACL and member bans after using the ban command
• Improve the clarity of the unban command. Users marked as banned by the Flooding and FirstMessageIsMedia protections can now be unbanned with the ban command. Using the unban command without true will now warn the user that room level bans will not be overridden. by @Gnuxie in #402
• Fix config.protectAllJoinedRooms leaking into explicitly protected rooms and mjolnir trying to protect watched lists in some circumstances. You would only have been impacted by this if you ran latest. by @Gnuxie in #385
• Add policy list shortcodes to status command output by @tanriol in #312
• Fix typo in config set command response by @sharp-tailed in #382
• Fixed a bug where Mjolnir would temporarily apply a stale m.room.server_acl event to rooms during batching by @Gnuxie in #33

• Fix example to have correct incantation by @erikjohnston in #358
