 ## What's new
 
+- **1.7.0 — Evidence-backed evaluations:** Added durable eval suites, runs, comparisons, invalidation and rescoring, correctness/quality/performance gates, cost per verified success, and effort recommendations. The complete workflow is available through the CLI; MCP only mirrors selected surfaces and is optional. Security gates now cover repository leaks, vulnerable dependencies, workflow hardening, privacy, and forbidden staged files. See the [Eval Contract](docs/planr-spec/EVAL_CONTRACT_V1.md), [CLI Reference](docs/CLI_REFERENCE.md), and the [1.7.0 changelog](CHANGELOG.md#170---2026-07-22).
 - **1.6.0 — Human map observation:** Added a condensed boxed diagram, live two-terminal watching, accessible state colors, and clearer satisfied dependency routes. These views are intentionally for human supervision; agents keep using the default tree or JSON snapshots. See [Task Graph Model](docs/TASK_GRAPH_MODEL.md), [CLI Reference](docs/CLI_REFERENCE.md), and the [1.6.0 changelog](CHANGELOG.md#160---2026-07-21).
 - **1.5.2 — Standalone core, optional Switchloom:** Planr consumes provider-neutral repository declarations and route evidence only; it works without any routing files, and requested-only routing metadata is not execution proof. Optional model-routing lifecycle is external, with [Switchloom v0.2.1](https://github.com/instructa/switchloom/releases/tag/v0.2.1) verified as the repository-local handoff outside Planr. Start with [Model Routing](docs/MODEL_ROUTING.md), [Switchloom](https://switchloom.ai), the [Switchloom repository](https://github.com/instructa/switchloom), its tagged [setup quickstart](https://github.com/instructa/switchloom/blob/v0.2.1/README.md#setup-from-the-website) and [lifecycle docs](https://github.com/instructa/switchloom/blob/v0.2.1/docs/preset-composition.md#repository-lifecycle-commands), and the [Changelog](CHANGELOG.md).
 - **1.4.0 — Verified presets:** Added policy-driven composition, evaluation, signed registry evidence, and the public catalog. See the [1.4.0 release notes](https://github.com/instructa/planr/releases/tag/v1.4.0).
