Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.

The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
The product is converging on a model where AI Agents handle routine conversations while human agents handle escalations, with channels increasingly auto-enrolled (missed calls become conversations, calendar events surface in the inbox). The channel expansion pace (TikTok, Microsoft 365, Google Calendar within weeks) suggests a deliberate push to cover every channel a business customer might use.
Voice channel integration — handling inbound calls with AI Agents rather than just converting missed calls into follow-ups — would complete the omnichannel picture respond.io is assembling.

Misskey's last two cycles are about making servers cheaper and safer to run: tighter Sentry data-collection defaults in 2026.10, lower memory and newer Node versions in 2026.11. Each one carries a breaking requirement that admins must check before upgrading.
Expect 2026.11.x patch releases for upgrade problems, especially around custom NODE_OPTIONS and systemd units. The entries do not show what the next feature cycle will target.
