+- **`kosli evaluate trail` and `kosli evaluate trails`** — evaluate one or more trails against a [Rego](https://www.openpolicyagent.org/docs/latest/policy-language/) policy and get a structured pass/fail decision. Use `--attestations` to filter which attestations are checked, and `--output json` for machine-readable results. Exit code reflects the policy decision, making it ideal for CI/CD gates. See the [evaluate trail](/client_reference/kosli_evaluate_trail) and [evaluate trails](/client_reference/kosli_evaluate_trails) reference for details.
+- **Multi-environment K8s reporting** — `kosli snapshot k8s` now accepts a `--config-file` flag to report multiple Kosli environments in a single command. Define environment-to-namespace mappings in a YAML file instead of running the command once per environment. See the [snapshot k8s](/client_reference/kosli_snapshot_k8s) reference.
+- **Helm chart v2.0.0** — the [k8s-reporter Helm chart](/helm/k8s_reporter) now uses a `reporterConfig.environments` list, enabling multi-environment reporting from a single chart installation. This is a breaking change from v1.x — see the chart README for migration steps.
