v2.14.0-rc1

We're pleased to be publishing the release candidate for v2.14.0 (the official release should follow within two weeks or so). This release contains primarily bug fixes, with the addition of some new authentication mechanisms for integrating with web clients.

This release includes changes to the config file format, all of which are fully backwards-compatible and do not require updating the file before upgrading. It includes no changes to the database file format.

Many thanks to @al3xandros, donio, @eeeeeta, @emersion, @Eriner, @eskimo, @Herringway, @jwheare, @knolley, pathof, @poVoq, @progval, @RNDpacman, and @xnaas for contributing patches, reporting issues, and helping test.

Config changes

• Added accounts.oauth2 and accounts.jwt-auth blocks for configuring OAuth2 and JWT authentication (#2004)
• Added protocol and local-address options to accounts.registration.email-verification, to force emails to be sent over IPv4 (or IPv6) or to force the use of a particular source address (#2142)
• Added limits.realnamelen, a configurable limit on the length of realnames. If unset, no limit is enforced beyond the IRC protocol line length limits (the previous behavior). (#2123, thanks @eskimo!)
• Added the accept-hostname option to the webirc config block, allowing Ergo to accept hostnames passed from reverse proxies on the WEBIRC line. Note that this will have no effect under the default/recommended configuration, in which cloaks are used instead (#1686, #2146, thanks @RNDpacman!)
• The default/recommended value of limits.chan-list-modes (the size limit for ban/except/invite lists) was raised to 100 (#2081, #2165, #2167)

Added

• Added support for the OAUTHBEARER SASL mechanism, allowing Ergo to interoperate with Gamja and an OAuth2 provider (#2004, #2122, thanks @emersion!)
• Added support for the IRCV3BEARER SASL mechanism, allowing Ergo to accept OAuth2 or JWT bearer tokens (#2158)
• Added support for the legacy rfc1459 and rfc1459-strict casemappings (#2099, #2159, thanks @xnaas!)
• The new ergo defaultconfig subcommand prints a copy of the default config file to standard output (#2157, #2160, thanks @al3xandros!)

Fixed

• NICK and QUIT from invisible members of auditorium channels are no longer recorded in history (#2133, #2137, thanks @knolley and @poVoq!)
• If channel registration was disabled, registered channels could become inaccessible after rehash; this has been fixed (#2130, thanks @eeeeeta!)
• Attempts to use unrecognized SASL mechanisms no longer count against the login throttle, improving compatibility with Pidgin (#2156, thanks donio and pathof!)
• Fixed database autoupgrade on Windows, which was previously broken due to the use of a colon in the backup filename (#2139, #2140, thanks @Herringway!)
• Fixed handling of NS CERT ADD <user> <fp> when an unprivileged user invokes it on themself (#2128, #2098, thanks @Eriner!)
• Fixed missing human-readable trailing parameters for two multiline FAIL messages (#2043, #2162, thanks @jwheare and @progval!)
• Fixed symbol sent by 353 RPL_NAMREPLY for secret channels (#2144, #2145, thanks savoyard!)

Changed

• Trying to claim a registered nickname that is also actually in use by another client now produces 433 ERR_NICKNAMEINUSE as expected (#2135, #2136, thanks savoyard!)
• SAMODE now overrides the enforcement of limits.chan-list-modes (the size limit for ban/except/invite lists) (#2081, #2165)
• Certain unsuccessful MODE changes no longer send 324 RPL_CHANNELMODEIS and 329 RPL_CREATIONTIME (#2163)
• Debug logging for environment variable configuration overrides no longer prints the value, only the key (#2129, #2132, thanks @eeeeeta!)

Internal

• Official release builds use Go 1.22.4
