#### ⚠️ Breaking Changes - Migration Required

This release enforces stricter validation and **removes support for
deprecated YAML syntax**. You must update your test files when
upgrading.

##### Required Changes to Your YAML Files

##### 1. Replace `contains` with `regexp`

```yaml

# ❌ Old (no longer works)
logs:
  - logql: '{job="app"}'
    contains: ["error"]

# ✅ New
logs:
  - logql: '{job="app"}'
    regexp: "error"
```

```diff
logs:
  - logql: '{job="app"}'
-   contains: ["error"]
+   regexp: "error"
```

##### 2. Remove `spans` array from traces

```yaml

# ❌ Old (no longer works)
traces:
  - traceql: '{}'
    spans:
      - name: "GET /api"

# ✅ New
traces:
  - traceql: '{}'
    equals: "GET /api"
```

```diff
traces:
  - traceql: '{}'
-   spans:
-     - name: "GET /api"
+   equals: "GET /api"
```

##### 3. Update profile flamebearers

```yaml

# ❌ Old (no longer works)
profiles:
  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:
      contains: "my-function"

# ✅ New
profiles:
  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:
      equals: "my-function"
```

```diff
profiles:
  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:
-     contains: "my-function"
+     equals: "my-function"
```

***

##### What Changed

- **Enforced validation for deprecated fields** - Previously deprecated
syntax now causes test failures
- **Added comprehensive test coverage** - 70+ unit tests ensure proper
validation of all YAML configurations
- **Stricter input validation** - HTTP methods, schemes, status codes,
and request bodies are now strictly validated

These changes improve the reliability and consistency of OATS test
definitions.
