+### Pull Request checklist
+
+#### All query authors
+
+- [ ] A change note is added if necessary. See [the documentation](https://github.com/github/codeql/blob/main/docs/change-notes.md) in this repository.
+- [ ] All new queries have appropriate `.qhelp`. See [the documentation](https://github.com/github/codeql/blob/main/docs/query-help-style-guide.md) in this repository.
+- [ ] QL tests are added if necessary. See [Testing custom queries](https://docs.github.com/en/code-security/codeql-cli/using-the-advanced-functionality-of-the-codeql-cli/testing-custom-queries) in the GitHub documentation.
+- [ ] New and changed queries have correct query metadata. See [the documentation](https://github.com/github/codeql/blob/main/docs/query-metadata-style-guide.md) in this repository.
+
+#### Internal query authors only
+
+- [ ] Autofixes generated based on these changes are valid, only needed if this PR makes significant changes to `.ql`, `.qll`, or `.qhelp` files. See [the documentation](https://github.com/github/codeql-team/blob/main/docs/best-practices/validating-autofix-for-query-changes.md) (internal access required).
+- [ ] Changes are validated [at scale](https://github.com/github/codeql-dca/) (internal access required).
+- [ ] Adding a new query? Consider also [adding the query to autofix](https://github.com/github/codeml-autofix/blob/main/docs/updating-query-support.md#adding-a-new-query-to-the-query-suite).

+## 2.1.0
+
+### New Features
+
+* Added a new predicate `DataFlow::getARuntimeTarget` for getting a function that may be invoked by a `Call` expression. Unlike `Call.getTarget` this new predicate may also resolve function pointers.
+* Added the predicate `mayBeFromImplicitlyDeclaredFunction()` to the `Call` class to represent calls that may be the return value of an implicitly declared C function.
+* Added the predicate `getAnExplicitDeclarationEntry()` to the `Function` class to get a `FunctionDeclarationEntry` that is not implicit.
+* Added classes `RequiresExpr`, `SimpleRequirementExpr`, `TypeRequirementExpr`, `CompoundRequirementExpr`, and `NestedRequirementExpr` to represent C++20 requires expressions and the simple, type, compound, and nested requirements that can occur in `requires` expressions.
+
+### Minor Analysis Improvements
+
+* The function call target resolution algorithm has been improved to resolve more calls through function pointers. As a result, dataflow queries may have more results.
+
+## 2.0.2
+
+### Minor Analysis Improvements
+
+* Added taint flow model for `fopen` and related functions.
+* The `SimpleRangeAnalysis` library (`semmle.code.cpp.rangeanalysis.SimpleRangeAnalysis`) now generates more precise ranges for calls to `fgetc` and `getc`.
+
+## 2.0.1
+
+No user-facing changes.
+
+## 2.0.0
+
+### Breaking Changes
+
+* Deleted many deprecated taint-tracking configurations based on `TaintTracking::Configuration`. 
+* Deleted many deprecated dataflow configurations based on `DataFlow::Configuration`. 
+* Deleted the deprecated `hasQualifiedName` and `isDefined` predicates from the `Declaration` class, use `hasGlobalName` and `hasDefinition` respectively instead.
+* Deleted the `getFullSignature` predicate from the `Function` class, use `getIdentityString(Declaration)` from `semmle.code.cpp.Print` instead.
+* Deleted the deprecated `freeCall` predicate from `Alloc.qll`. Use `DeallocationExpr` instead.
+* Deleted the deprecated `explorationLimit` predicate from `DataFlow::Configuration`, use `FlowExploration<explorationLimit>` instead.
+* Deleted the deprecated `getFieldExpr` predicate from `ClassAggregateLiteral`, use `getAFieldExpr` instead.
+* Deleted the deprecated `getElementExpr` predicate from `ArrayOrVectorAggregateLiteral`, use `getAnElementExpr` instead.
+
+### New Features
+
+* Added a class `C11GenericExpr` to represent C11 generic selection expressions. The generic selection is represented as a `Conversion` on the expression that will be selected.
+* Added subclasses of `BuiltInOperations` for the `__is_scoped_enum`, `__is_trivially_equality_comparable`, and `__is_trivially_relocatable` builtin operations.
+* Added a subclass of `Expr` for `__datasizeof` expressions.
+
+### Minor Analysis Improvements
+
+* Added a data flow model for `swap` member functions, which were previously modeled as taint tracking functions. This change improves the precision of queries where flow through `swap` member functions might affect the results.
+* Added a data flow model for `realloc`-like functions, which were previously modeled as a taint tracking functions. This change improves the precision of queries where flow through `realloc`-like functions might affect the results.
+
+## 1.4.2
+
+No user-facing changes.
+
+## 1.4.1
+
+No user-facing changes.
+
+## 1.4.0
+
+### New Features
+
+* A `getTemplateClass` predicate was added to the `DeductionGuide` class to get the class template for which the deduction guide is a guide.
+* An `isExplicit` predicate was added to the `Function` class that determines whether the function was declared as explicit.
+* A `getExplicitExpr` predicate was added to the `Function` class that yields the constant boolean expression (if any) that conditionally determines whether the function is explicit.
+* A `isDestroyingDeleteDeallocation` predicate was added to the `NewOrNewArrayExpr` and `DeleteOrDeleteArrayExpr` classes to indicate whether the deallocation function is a destroying delete. 
+
+### Minor Analysis Improvements
+
+* The controlling expression of a `constexpr if` is now always recognized as an unevaluated expression.
+* Improved performance of alias analysis of large function bodies. In rare cases, alerts that depend on alias analysis of large function bodies may be affected.
+* A `UsingEnumDeclarationEntry` class has been added for C++ `using enum` declarations. As part of this, synthesized `UsingDeclarationEntry`s are no longer emitted for individual enumerators of the referenced enumeration.
+
+## 1.3.0
+
+### New Features
+
+* Models-as-data alert provenance information has been extended to the C/C++ language. Any qltests that include the edges relation in their output (for example, `.qlref`s that reference path-problem queries) will need to be have their expected output updated accordingly.
+* Added subclasses of `BuiltInOperations` for `__builtin_has_attribute`, `__builtin_is_corresponding_member`, `__builtin_is_pointer_interconvertible_with_class`, `__is_assignable_no_precondition_check`, `__is_bounded_array`, `__is_convertible`, `__is_corresponding_member`, `__is_nothrow_convertible`, `__is_pointer_interconvertible_with_class`, `__is_referenceable`, `__is_same_as`, `__is_trivially_copy_assignable`, `__is_unbounded_array`, `__is_valid_winrt_type`, `_is_win_class`, `__is_win_interface`, `__reference_binds_to_temporary`, `__reference_constructs_from_temporary`, and `__reference_converts_from_temporary`.
+* The class `NewArrayExpr` adds a predicate `getArraySize()` to allow a more convenient way to access the static size of the array when the extent is missing.
+
+## 1.2.0
+
+### New Features
+
+* The syntax for models-as-data rows has been extended to make it easier to select sources, sinks, and summaries that involve templated functions and classes. Additionally, the syntax has also been extended to make it easier to specify models with arbitrary levels of indirection. See `dataflow/ExternalFlow.qll` for the updated documentation and specification for the model format.
+* It is now possible to extend the classes `AllocationFunction` and `DeallocationFunction` via data extensions. Extensions of these classes should be added to the `lib/ext/allocation` and `lib/ext/deallocation` directories respectively.
+
+### Minor Analysis Improvements
+
+* The queries "Potential double free" (`cpp/double-free`) and "Potential use after free" (`cpp/use-after-free`) now produce fewer false positives.
+* The "Guards" library (`semmle.code.cpp.controlflow.Guards`) now also infers guards from calls to the builtin operation `__builtin_expect`. As a result, some queries may produce fewer false positives.
+
