Changelog

What changed in Zihin.

Product milestones, month by month — in human language, not endpoint language.

May 2026

  1. Feature

    Session Control — pause, intervene and block without touching the agent

    Five new levers to control attendance without editing the agent: suspend a specific conversation, take over manually replying through the agent's own channel, cancel an in-progress turn (loop or wrong answer), block a contact across all your tenant's agents, and view a contact's aggregated cross-session history. No quota cost when control blocks.

  2. Feature

    Builder Agent — edit your agents by chatting with AI

    Builder Chat is now an AI agent that understands your agents' configuration and proposes validated changes. You describe what you want to adjust — persona, tools, triggers, MCP servers, security policies, skills, workflow, database connections — and Builder creates proposals you approve with one click. Each proposal is validated before becoming a real change, and nothing applies without your confirmation.

  3. Feature

    Long-term memory — agents remember contacts across sessions

    Agent memory is now persistent and cross-session: what it learns about a contact in one conversation is available in the next, even days later. You choose which agents need long-term memory (continuous support, follow-up, customer profile) and which don't (one-shot tasks, public agents without a fixed identity) — per-agent control, without affecting the others.

April 2026

  1. ReleasePublic beta

    Public site launched in beta

    New routes (/sobre, /contato, /seguranca), LGPD consent banner, legal pages (terms, privacy, cookies) and SEO foundations (sitemap, JSON-LD). Ready for organic traffic.

  2. Feature

    Workroom: live sessions and replay

    Every execution event now streams tenant-wide via SSE. Full replay of past sessions, with phases, tool calls and per-call latencies.

  3. Feature

    Zihin Tunnel in production

    First pilot client connected via Tunnel. Outbound WebSocket, on-premise credentials, zero open ports on the client's firewall.

  4. Feature

    Multi-agent with team memory

    An agent can invoke another agent via the invoke_agent tool. Shared memory across agents in the same pipeline. Depth limit controlled by policy.
