## 0.6.27
No user-facing changes.

### Major Analysis Improvements
* Fixed alert messages in `actions/artifact-poisoning/critical` and `actions/artifact-poisoning/medium` as they previously included a redundant placeholder in the alert message that would on occasion contain a long block of yml that makes the alert difficult to understand. Also improved the wording to make it clearer that it is not the artifact that is being poisoned, but instead a potentially untrusted artifact that is consumed. Finally, changed the alert location to be the source, to align more with other queries reporting an artifact (e.g. zipslip) which is more useful.
### Minor Analysis Improvements
* The query `actions/missing-workflow-permissions` no longer produces false positive results on reusable workflows where all callers set permissions.

## 10.1.0
### New Features
* A new predicate `getSwitchCase` was added to the `SwitchStmt` class, which yields the `n`th `case` statement from a `switch` statement.
* Data flow barriers and barrier guards can now be added using data extensions. For more information see [Customizing library models for C and C++](https://codeql.github.com/docs/codeql-language-guides/customizing-library-models-for-cpp/).
### Minor Analysis Improvements
* Added taint flow models for the `Strsafe.h` header from the Windows SDK.
## 10.0.0
### Breaking Changes
* The deprecated `NonThrowingFunction` class has been removed, use `NonCppThrowingFunction` instead.
* The deprecated `ThrowingFunction` class has been removed, use `AlwaysSehThrowingFunction` instead.
### New Features
* Added a subclass `AutoconfConfigureTestFile` of `ConfigurationTestFile` that represents files created by GNU autoconf configure scripts to test the build configuration.
## 9.0.0
### Breaking Changes
* The `SourceModelCsv`, `SinkModelCsv`, and `SummaryModelCsv` classes and the associated CSV parsing infrastructure have been removed from `ExternalFlow.qll`. New models should be added as `.model.yml` files in the `ext/` directory.
### New Features
* Added a subclass `MesonPrivateTestFile` of `ConfigurationTestFile` that represents files created by Meson to test the build configuration.
* Added a class `ConstructorDirectFieldInit` to represent field initializations that occur in member initializer lists.
* Added a class `ConstructorDefaultFieldInit` to represent default field initializations.
* Added a class `DataFlow::IndirectParameterNode` to represent the indirection of a parameter as a dataflow node.
* Added a predicate `Node::asIndirectInstruction` which returns the `Instruction` that defines the indirect dataflow node, if any.
* Added a class `IndirectUninitializedNode` to represent the indirection of an uninitialized local variable as a dataflow node.
### Minor Analysis Improvements
* Added `HttpReceiveHttpRequest`, `HttpReceiveRequestEntityBody`, and `HttpReceiveClientCertificate` from Win32's `http.h` as remote flow sources.
* Added dataflow through members initialized via non-static data member initialization (NSDMI).
## 8.0.3
No user-facing changes.
## 8.0.2
No user-facing changes.
## 8.0.1
### Minor Analysis Improvements
* Inline expectations test comments, which are of the form `// $ tag` or `// $ tag=value`, are now parsed more strictly and will not be recognized if there isn't a space after the `$` symbol.
## 8.0.0
### Breaking Changes
* CodeQL version 2.24.2 accidentally introduced a syntactical breaking change to `BarrierGuard<...>::getAnIndirectBarrierNode` and `InstructionBarrierGuard<...>::getAnIndirectBarrierNode`. These breaking changes have now been reverted so that the original code compiles again.
* `MustFlow`, the inter-procedural must-flow data flow analysis library, has been re-worked to use parameterized modules. Like in the case of data flow and taint tracking, instead of extending the `MustFlowConfiguration` class, the user should now implement a module with the `MustFlow::ConfigSig` signature, and instantiate the `MustFlow::Global` parameterized module with the implemented module.
### Minor Analysis Improvements
* Refactored the "Year field changed using an arithmetic operation without checking for leap year" query (`cpp/leap-year/unchecked-after-arithmetic-year-modification`) to address large numbers of false positive results.
### Bug Fixes
* The `allowInterproceduralFlow` predicate of must-flow data flow configurations now correctly handles direct recursion.
