v2.0.0

We're pleased to announce Oragono 2.0.0, a major update with a wide range of enhancements and fixes. Highlights include:

  • Support for storing chat history in a MySQL backend
  • Full "bouncer" functionality, including "always-on" clients that remain present on the server even when disconnected
  • LDAP support contributed by @mattouille
  • Support for the ratified labeled-response IRCv3 capability
  • Enhanced support for Kubernetes
  • Many new service commands, improving management of client certificates, vhosts, and channel ownership

Many thanks to @csmith, @mattouille, and @xPaw for contributing patches, to @csmith and @wrmsr for contributing code reviews, to @bogdomania, @brenns10, @daurnimator, @ekianjo, horseface, @ivucica, @jesopo, @jwheare, KoDi, lover, @notbandali, @poVoq, @TETYYS, and @zaher for reporting issues, and to @bogdomania and Nuve for contributing translations.

This release includes changes to the config file format, including two breaking changes:

  1. Backwards compatibility with the old server.listen format for configuring listeners has been removed; you must now use the server.listeners format that was introduced in 1.2.0.
  2. The two sections server.connection-limits and server.connection-throttling have been consolidated into one new section, server.ip-limits.

Other changes to the config file format are backwards compatible and do not require updating before restart. To minimize potential downtime, we suggest the following workflow:

  1. Without upgrading your oragono binary, edit your config file to add new server.listeners and server.ip-limits sections, based on the example config file
  2. Rehash your server, confirming that the new config file is valid for for the previous version of the server
  3. Upgrade your oragono binary to the new 2.0.x version and restart your server
  4. Once your deployment is stable on 2.0.x, delete the old server.listen, server.connection-limits, and server.connection-throttling sections from your config, and rehash your server to confirm

This release includes a database change. If you have datastore.autoupgrade set to true in your configuration, it will be automatically applied when you restart Oragono. Otherwise, you can update the database manually by running oragono upgradedb (see the manual for complete instructions).
