+* 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.

+## 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).

+## 1.6.1
+
+### Minor Analysis Improvements
+
+* Added `AllocationFunction` models for `aligned_alloc`, `std::aligned_alloc`, and `bsl::aligned_alloc`.
+* The "Comparison of narrow type with wide type in loop condition" (`cpp/comparison-with-wider-type`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
+* The "Multiplication result converted to larger type" (`cpp/integer-multiplication-cast-to-long`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
+* The "Suspicious add with sizeof" (`cpp/suspicious-add-sizeof`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
+* The "Wrong type of arguments to formatting function" (`cpp/wrong-type-format-argument`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
+* The "Implicit function declaration" (`cpp/implicit-function-declaration`) query has been upgraded to `high` precision. However, for `build-mode: none` databases, it no longer produces any results. The results in this mode were found to be very noisy and fundamentally imprecise.
+
+## 1.6.0
+
+### Query Metadata Changes
+
+* The `@security-severity` metadata of `cpp/cgi-xss` has been increased from 6.1 (medium) to 7.8 (high).
+
+### Minor Analysis Improvements
+
+* The "Extraction warnings" (`cpp/diagnostics/extraction-warnings`) diagnostics query no longer yields `ExtractionRecoverableWarning`s for `build-mode: none` databases. The results were found to significantly increase the sizes of the produced SARIF files, making them unprocessable in some cases.
+* Fixed an issue with the "Suspicious add with sizeof" (`cpp/suspicious-add-sizeof`) query causing false positive results in `build-mode: none` databases.
+* Fixed an issue with the "Uncontrolled format string" (`cpp/tainted-format-string`) query involving certain kinds of formatting function implementations.
+* Fixed an issue with the "Wrong type of arguments to formatting function" (`cpp/wrong-type-format-argument`) query causing false positive results in `build-mode: none` databases.
+* Fixed an issue with the "Multiplication result converted to larger type" (`cpp/integer-multiplication-cast-to-long`) query causing false positive results in `build-mode: none` databases.
