BotKit 0.4.0

Released on March 30, 2026.

@fedify/botkit

• Upgraded Fedify to 2.1.2.

  • BotKit now targets Fedify 2.0's modular package layout, using @fedify/vocab, @fedify/vocab-runtime, and @fedify/denokv where appropriate.
  • Message.language and SessionPublishOptions.language now use Intl.Locale instead of LanguageTag.
  • Bot software versions now use plain strings instead of SemVer objects.
  • Removed the parseSemVer(), SemVer, LanguageTag, and parseLanguageTag() public exports.

• BotKit now acknowledges unverified remote Delete activities signed by permanently gone actors with 202 Accepted instead of 401 Unauthorized.

  • This applies only when Fedify reports a keyFetchError and the remote actor's key fetch returned 410 Gone.
  • The unverified activity is not passed to BotKit event handlers, but the successful response stops repeated redelivery attempts from the remote server.

• Added FEP-5711 inverse properties to the bot actor's outbox and followers collections.

• Added a remote follow button to the web interface. [#10, #14 by Hyeonseo Kim]

  • Added a Follow button on the bot's profile page that allows users to follow the bot from their own fediverse instance without manual searching.
  • When clicked, the button opens a modal dialog where users can enter their fediverse handle (e.g., @username@instance.com).
  • The feature uses WebFinger to discover the user's instance and automatically redirects to the appropriate follow page using the OStatus subscribe protocol.

• Added Session.republishProfile() to broadcast profile changes to followers. [#18]

  • The new method sends an ActivityPub Update activity for the bot actor to the bot's followers.
  • This makes profile updates such as display name, bio, avatar, and header image propagate without waiting for the next post.

@fedify/botkit-postgres

• Added a new PostgreSQL repository package, @fedify/botkit-postgres, which provides PostgresRepository, PostgresRepositoryOptions, and initializePostgresRepositorySchema(). [#11, #19]
