## Current Release

NVIDIA NeMo Relay 0.5 adds dynamic plugin SDKs and lifecycle controls, verified
CLI installers and readiness diagnostics, stable token and cost field semantics,
and stronger request and trace lineage behavior.

The most important compatibility notes are:

* Plugin configuration now lives in `plugins.toml`. Move plugin settings out of
  `config.toml`; the `--plugin-config` CLI option has been removed.
* Registered LLM request and tool execution intercepts now return canonical
  outcomes. Rebuild development native plugins and `grpc-v1` workers against
  0.5.
* The experimental `nemo-relay-wasm` package, Cursor CLI support, and
  patch-based integrations have been removed.
* Go and the raw C FFI remain experimental and source-first. Node.js 24 or
  newer remains the minimum supported Node.js version.

## Release Scope

This release includes:

* Dynamic plugin discovery, trust policy and attestation gates, and lifecycle
  controls through the `nemo-relay` CLI.
* A Rust native plugin SDK for trusted in-process `rust_dynamic` plugins, plus
  `grpc-v1` worker support through Rust and Python SDKs.
* Schema-aware dynamic-plugin configuration and editing through `plugins.toml`.
* Verified Unix and Windows CLI installers, and expanded `nemo-relay doctor`
  readiness diagnostics for agent hosts and plugin configuration.
* Canonical LLM request and tool execution intercept outcomes with ordered
  pending marks across the runtime and supported bindings.
* Automatic Dynamo session-lineage headers on managed LLM requests and
  turn-scoped CLI trace correlation.
* Stable normalized token and cost semantics for provider response codecs and
  ATOF, ATIF, OpenInference, and OpenTelemetry projections.
