Stalwart keeps filling in mail-standard gaps with a steady maintenance release
Stalwart is an all-in-one mail and collaboration server, and v0.16.10 is a characteristic release: a cluster of standards-compliance and configuration additions — IDN support, OAuth public-client handling, an IMAP extension, ACME key reuse — rather than a headline feature. The single visible entry shows maintenance-mode breadth, not directional change.
Chatwoot adds voice to close the last channel gap in its omnichannel support suite
Chatwoot is an open-source omnichannel customer-support platform spanning live chat, email, WhatsApp, social channels, and a help center, with an AI agent called Captain. The headline recent move is voice: phone and WhatsApp calls now run in beta, closing the one major channel gap in an otherwise text-complete product. Around it, steady investment in Captain (auto-syncing knowledge base, Custom Tools to call external APIs, mobile AI Assist), help-center depth (a documentation layout, LLM-aware articles, bulk and translation tooling), and agent-workflow polish (assignment policies, a Participating view).

The single visible entry shows maintenance-mode breadth, not directional change.
The work points at closing protocol gaps and smoothing operations — root redirects, ACME renewal key reuse, OAuth edge cases — to make Stalwart a drop-in replacement across more deployments. This is consolidation: widening compatibility so fewer environments hit a missing-standard wall.
Expect continued point releases in the same vein: incremental RFC coverage and deployment-ergonomics fixes. With only one entry visible, there is no signal of a larger architectural shift.

Chatwoot is rounding out into a complete omnichannel support suite — adding voice to become genuinely all-channel while making Captain more capable and self-maintaining through fresh knowledge bases, external tool calls, and handoff tuning. The throughline is cutting manual upkeep and channel-switching for support teams, and pushing AI deeper into both answering and knowledge management.
Expect voice to mature out of beta with call routing and reporting (the team flagged these as next), and Captain to keep gaining agentic capability, given the voice-beta roadmap notes and the Custom Tools and auto-sync cadence.
