v0.2.0

[0.2.0] - 2026-10-02

Added

• Opt-in routes[].input.developer_role_as_user to wrap developer messages as
  tagged user messages at their original positions, with a fixed convention
  appended to top-level instructions. The setting defaults to false and does
  not affect native ChatGPT or OpenAI API requests.
• Coverage for message order, string and content-block preservation, stable
  translated prefixes, route isolation, and JSON/SSE tool-call round trips.

Breaking

• Removed routes[].input.developer_role_as_system. Delete this field from
  existing configurations before upgrading; validation rejects it. Enable
  developer_role_as_user where tagged-user conversion is needed. With the new
  setting disabled, developer messages and top-level instructions are preserved.

v0.1.0

[0.1.0] - 2026-09-30

Added

• Initial public release of the loopback Responses API router, native catalog
  merge, self-hosted routes, and macOS LaunchAgent/Linux systemd user-service
  lifecycle commands.
• setup for safe first-run configuration, bundled native catalog generation,
  service installation, health verification, and optional Codex configuration.
• Local release packaging for darwin/arm64 and linux/amd64 artifacts.
• MIT License.

Changed

• Router configuration now follows XDG configuration paths and generated
  catalogs follow XDG data paths.

Breaking

• The former ~/.local/lib/codex-model-router/ combined installation is no
  longer the default. Existing custom configuration and catalog paths remain
  supported through --config and explicit catalog.output_file values; see
  the migration instructions in the configuration reference.
