Release Notes

ergochat/ergo (ghcr.io/ergochat/ergo)

v2.18.0

Compare Source

We're pleased to be publishing v2.18.0, a new stable release. This release adds support for PostgreSQL and SQLite as history backends, expands the HTTP API, and includes bug fixes and minor improvements.

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.

Due to the additional database drivers included in the default build, the size of the Ergo executable binary has increased since v2.17.0 (for example, the Linux binary for x86-64 has increased from 16.2 MiB to 26.1 MiB). See docs/BUILD.md if you need to build a smaller binary. Conversely, if you were already building from source, you may need to adjust your build commands in order to maintain parity; consult that file for details.

Config changes

• Added server.postgresql block to configure a PostgreSQL history backend. (#​2322, #​2347)
• Added server.sqlite block to configure a SQLite history backend. (#​2352)
• Added metadata.operator-only-modification to restrict metadata changes to IRC operators with the metadata capability (#​2287, #​2369, thanks @​clbm87!)
• Added server.initial-notice to send a configurable notice to clients immediately after they connect, which can be used for open proxy detection (e.g., with HOPM) (#​2317, thanks Stryker!)

Added

• Added support for PostgreSQL and SQLite as history backends (#​2322, #​2352, thanks @​felix, @​NyaaaWhatsUpDoc, @​poVoq!)
• Added new HTTP API endpoints (thanks @​clbm87, flurry, @​furudean, @​mauropcorrea!):
  • /v1/list to list channels (#​2358)
  • /v1/defcon to view or modify the DEFCON level (#​2359)
  • /v1/ns/passwd to change account passwords (#​2329)
• Added support for draft/ACCOUNTREQUIRED in 005 ISUPPORT tokens when accounts.require-sasl is enabled (#​2341)

Fixed

• Push notifications now include the msgid tag, as required by the specification (#​2350)
• Fixed some cases where environment variable config overrides did not apply as expected (e.g., individual oper entries can now be overridden without replacing the entire opers block) (#​2275, #​2362, thanks th0th!)
• Fixed error cases in CS DEOP and EXTJWT causing client disconnection (#​2345, #​2346, thanks @​k4ct0!)
• Fixed some REDACT responses (#​2319, #​2320)
• Fixed some FAIL responses to WEBPUSH (#​2351)
• The +l (user limit) channel mode now rejects non-positive values with an appropriate error (#​2325, thanks @​progval!)
• Clients monitoring a user now receive METADATA notifications for that user even without the extended-monitor capability (#​2309, #​2310)
• Improved handling of PROXY protocol errors on proxy: true listeners (#​2334)
• The accounts.bcrypt-cost config value is now validated at config load time (#​2311, #​2312, thanks @​rys!)

Changed

• HTTP API: reorganized NickServ-related endpoints under a /v1/ns/ prefix (/v1/ns/info, /v1/ns/list, /v1/ns/passwd). The previous endpoint names (/v1/account_details, /v1/account_list) are retained as aliases for backwards compatibility. (#​2329)
• The /v1/check_auth API endpoint now supports certificate fingerprint authentication (#​2354, thanks flurry!)
• Reduced the deadline for proxy: true listeners to read the PROXY protocol header from 1 minute to 5 seconds (#​2334)

Internal

• Added build tags to control which optional features are built; see docs/BUILD.md for details (#​2356)
• Official release builds use Go 1.26.1 (#​2330)
