v1.4.0 — 2026-10-02
Large saved attachments can be read in chunks and searched across extracted text. Excel keeps sheets, cell addresses and numbers; formulas are not executed. For a scanned PDF, the model sees the first four pages and discloses a partial view of longer files.
Migrate from OpenClaw in “Import”: upload an export, review the preview and apply your selection. A backup is made before applying; results and rollback are in the history. Warnings and skipped items need your decision; migration does not promise support for every third-party plugin.
Update Core in “System & settings” and modules in “Plugins”. Versions are independent: app and its module 1.1.6, Telegram 1.0.3, MAX 1.0.2. After updating, check your agent, attachments and channel on your own installation.
v1.0 — baseline
The baseline capabilities of the v1.0 line, as a reference point for later
changes.
A finished product, not a framework. A single self-hosted service combines
the control-plane and the turn engine; a typical install is one service plus
PostgreSQL.
Host-native, no Docker. Deployed as a release tarball managed by systemd;
no containers or orchestrators.
Multi-agent orchestration with sub-agents and reasoning strategies
(plan-steps, reflect, debate, best-of-N, self-heal).
First-class agents with personas, a structured prompt and a per-agent
model.
Long-term memory (Einstein) — facts extracted as reviewable claims and
promoted to memory; recall is wrapped in a data-fence against prompt injection.
Knowledge / RAG with citations, plus deep_research for multi-step
reports.
Channels — Telegram, Bitrix24, SIP telephony and the mobile and desktop
app, extended by installable connectors in later releases.
OpenAI-compatible API — POST /v1/chat/completions with SSE streaming.
No mandatory paid models — runs on free/local models and a Codex/ChatGPT
subscription transport; per-tenant BYOK is optional.
Security as a baseline property — an encrypted credential vault, enterprise
SSO (SAML / LDAP / SCIM / OIDC), Postgres Row-Level Security for tenant
isolation, human-in-the-loop approval gates and audit.
A plugin marketplace with one-click, host-native install.
