What is Converse.js?

Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.

Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.

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.

Converse.js vs Ergo: editorial side-by-side

C2.5

Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.

◆ Current state

Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.

◆ Where it's heading

The project is in a stabilisation phase on the 14 line, with encryption correctness as the main concern. Releases are months apart.

◆ Prediction

Expect further 14.0.x patches for encryption and browser compatibility; no next major is signalled.

2.5

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.
