build version is visible in the Admin UI and in the
API explorer (Swagger).
v1.4.5 — 2026-10-09
Security
Go 1.26.9 includes security fixes for the standard library.
Updated golang.org/x/net to 0.60.0 for HTTP/2 security fixes.
v1.4.4 — 2026-10-08
Fixed
OpenDesign and VoiceStudio preparation shows the current stage and downloaded bytes during installation, with clear failure stages and reasons that do not expose addresses, paths or secrets.
Preparing the studio cache no longer waits for an unrelated service-manager check; interruption cancels downloads and removes incomplete temporary preparation files.
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.
