Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.
After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
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).

Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
The product is in active maintenance mode rather than feature expansion. Investment is going into making the local sync layer more robust — mailbox conflict resolution, IMAP IDLE kill switch, vault retries on Linux — and the auth surface harder, with FIDO2 polish and TLS pin scoping. The arc reads as catching up on technical debt and shoring up security posture after a quieter year, not reshaping the product.
Expect the v3.2x cadence to continue with similar bug-fix and security flavor: more Go toolchain work, incremental IMAP edge-case handling, and continued error-UX tightening. The release notes do not surface anything that would hint at a v4 reshape or a meaningful new capability in the near term.

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.
