Full Changelog: https://github.com/theuselessai/plit-gw/commits/v0.3.2

v0.2.0 — CLI Tool & Foundation

msg-gateway v0.2.0

Second release — introduces the gw-cli command-line client, Cargo workspace restructure, and major feature additions across the gateway.

Binaries

Binary	Size	Description
gw-server	13M	Gateway server (renamed from msg-gateway)
gw-cli	6.6M	CLI client for chat, admin, and agent integration

Highlights

gw-cli — New CLI Tool

• Interactive chat REPL (gw-cli chat) with WebSocket streaming
• One-shot send (gw-cli send) — pipe-friendly, reads from stdin or --text
• WebSocket listener (gw-cli listen) — streams JSONL for agents and scripts
• Credential management (gw-cli credentials list/create/activate/deactivate)
• Health check (gw-cli health) — exit code 0/1 for scripting
• TTY-aware output: human-readable on terminal, JSON when piped
• Environment variable support: GATEWAY_URL, GATEWAY_TOKEN, GATEWAY_ADMIN_TOKEN

CEL-Based Guardrails

• Inbound message filtering with CEL expressions
• Hot-reload: rule changes apply without restart
• Actions: block (reject with 403) or log (audit only)
• XDG-compliant config path resolution

OpenCode Backend (Built-in)

• REST + SSE integration with session management
• File attachment support and long response handling
• Fire-and-forget with SSE response delivery

Named Backends with Per-Credential Routing

• Multiple backend instances (e.g. separate Pipelit + OpenCode)
• Each credential routes to a specific named backend
• External backend subprocess protocol

Other Improvements

• Cargo workspace restructure (gw-server + gw-cli)
• File upload API with multipart support
• Message format redesign: files[], extra_data, reply_to_message_id
• E2E test framework with Cucumber-JS (19+ scenarios)
• External backend adapter subprocess protocol
• Comprehensive documentation updates

Upgrade Notes

• Binary renamed: msg-gateway → gw-server
• Config route fields changed: workflow_id/trigger_id → workflow_slug/trigger_node_id (to match Pipelit API)
• New config fields: guardrails_dir, backends_dir, backend_port_range
