AgentOS 1.2.0 (LTS) - Process System, Syscall ABI 1.0 & Multi-Framework Ecosystem

AgentOS 1.2.0 (LTS)

AgentOS v1.2.0 is a major milestone release transforming AgentOS into a comprehensive, multi-tenant Agent Operating System Kernel.

Highlights

• Agent Process System: Dual-model execution (Task → Run → Attempt + AgentService → AgentInstance).
• Supervisor Engine: Self-healing auto-restart, heartbeat auto-reap, zero-downtime rolling upgrades (max_surge, max_unavailable), and automated rollback.
• Syscall ABI 1.0.0: Frozen POSIX-modeled system call table across 8 subsystems (Tool, Model, Memory, IPC, Runtime, Service, Resource, Effect).
• Durable IPC Subsystem: Cross-agent mailbox messaging, correlation ID, reply-to, and receiver deduplication.
• Kernel Effect Engine: Monotonic lease fencing, SHA-256 idempotency protection, and non-replayable UNKNOWN state.
• Conformance Certification Kit: Single-command verification suite (agentos conformance) producing AgentOS Compatible = PASS.
• Multi-Framework Ecosystem: Verified out-of-the-box adapters for LangGraph, AutoGen, CrewAI, OpenAI Agents SDK, and Custom In-House Agents.

Reliability & Soak Invariants

• Manual/Fixed-Host 72h/7d Evidence Completed: Verified zero lost tasks, zero lost IPC messages, and monotonic fencing (Evidence); scheduled CI reproduction pending self-hosted runners.

Frozen Public Contracts

• Syscall ABI: 1.0.0 (proto/agentos/syscall/v1/syscall.proto)
• IPC Protocol: agentos.ipc.v1 (proto/agentos/ipc/v1/ipc.proto)
• Service Protocol: agentos.service.v1 (proto/agentos/service/v1/service.proto)
• Effect Protocol: agentos.effect.v1 (proto/agentos/effect/v1/effect.proto)
• Runtime Protocol: agentos.runtime.v1 (proto/agentos/runtime/v1/runtime.proto)
• Gateway Protocol: agentos.gateway.v1 (proto/agentos/gateway/v1/gateway.proto)
• Control REST API: v1 (api/openapi/control-v1.yaml)
