### Breaking Changes
* The following queries have been removed from the `security-and-quality` suite.
They are not intended to produce user-facing
alerts describing vulnerabilities.

* `actions/reusable-workflow-sinks`

* `actions/reusable-workflow-summaries`
### Bug Fixes
* Assigned a `security-severity` to the query `actions/excessive-secrets-exposure`.
## 0.5.4
### New Features
* CodeQL and Copilot Autofix support for GitHub Actions is now Generally Available.
### Bug Fixes
* Alerts produced by the query `actions/missing-workflow-permissions` now include a minimal set of recommended permissions in the alert message, based on well-known actions seen within the workflow file.

## 4.3.0
### New Features
* New classes `TypeofType`, `TypeofExprType`, and `TypeofTypeType` were introduced, which represent the C23 `typeof` and `typeof_unqual` operators. The `TypeofExprType` class represents the variant taking an expression as its argument. The `TypeofTypeType` class represents the variant taking a type as its argument.
* A new class `IntrinsicTransformedType` was introduced, which represents the type transforming intrinsics supported by clang, gcc, and MSVC.
* Introduced `hasDesignator()` predicates to distinguish between designated and positional initializations for both struct/union fields and array elements.
* Added the `isVla()` predicate to the `ArrayType` class. This allows queries to identify variable-length arrays (VLAs).
