ergochat/ergo v2.16.0-rc1

on GitHub

We're pleased to be publishing the release candidate for v2.16.0 (the official release should follow within a week or so). This release contains bug fixes and some minor updates.

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 @csmith, @delthas, donio, @emersion, @KlaasT, @knolley, @Mailaender, and @prdes for reporting issues and helping test.

Config changes

• Added server.additional-isupport for publishing arbitrary ISUPPORT tokens (#2220, #2240)
• Added server.command-aliases to configure aliases for server commands (#2229, #2236)
• Added options to roleplay to customize the NUH's sent for NPC and SCENE. Roleplay remains deprecated and disabled by default. (#2237)

Security

• Mitigated HTTP DoS attacks by rejecting IRC sessions that begin with an HTTP verb, such as POST. If you were relying on this to create IRC sessions via an HTTP client, please open an issue. (#2239)

Added

• Added an HTTP API, providing programmatic access to Ergo functionality (#2231, thanks @KlaasT!)
• Added SAFERATE to 005 ISUPPORT tokens (#2223, thanks @delthas!)
• Added support for ed25519-sha256 for DKIM. However, enabling this algorithm is not recommended since mainstream email providers still do not support it. (#1041, #2242)

Fixed

• Fixed CHATHISTORY TARGETS from MySQL backend reporting incorrect timestamps when the server timezone is not UTC (#2224)
• Fixed batch name parameter in draft/isupport responses (#2253)
• Fixed NS UNREGISTER not deleting the stored push subscriptions (#2254)
• Fixed cases where NS SAREGISTER could create clients without applying the default user modes (#2252, #2254, thanks donio!)
• Improved validation of CHATHISTORY parameters (#2248, #2249, thanks @prdes!)
• Added validation to ensure the MOTD is UTF-8 when enforce-utf8 is enabled (the recommended default) (#2228, #2233, thanks @KlaasT!)
• The client's own QUIT line now respects the server-time capability (#2218, #2219)
• Fixed sending unnecessary replies to certain invalid MODE changes (#2213)
• Improved safety of ISUPPORT length limits (#2241)

Changed

• The draft/message-redaction capability is no longer advertised when allow-individual-delete is disabled (#2215, #2216, thanks @delthas!)
• Receiving the UTF-8 BOM (byte-order mark) at the start of an IRC connection now produces an explicit error (#2244, #2247, thanks @csmith, @Mailaender!)

Internal

• Release builds use Go 1.24.3 (#2217)
