What is Ergo?

Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.

Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.

What is Mailu?

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures

Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.

Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.

◆ Current state

Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.

◆ Where it's heading

This is a project with a stable release ritual and a narrow remit: be a modern IRC server that implements the spec correctly and runs as a single binary. Feature work arrives as specification support rather than product invention. The exception is the operational surface — history backends and the HTTP API — where Ergo has been steadily making itself easier to run alongside existing infrastructure instead of as a self-contained island.

◆ Prediction

The v2.19.0 final should follow its release candidate within a week or two on the established pattern; the config-format break flagged in that RC is the main thing operators will need to handle on upgrade.

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures

◆ Current state

Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.

◆ Where it's heading

The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.

◆ Prediction

The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.
