     Each language-specific directory contains further subdirectories that group queries based on their `@tags` or purpose.
     - Experimental queries and libraries are stored in the `experimental` subdirectory within each language-specific directory in the [CodeQL repository](https://github.com/github/codeql). For example, experimental Java queries and libraries are stored in `java/ql/src/experimental` and any corresponding tests in `java/ql/test/experimental`.
-    - Experimental queries need to include `experimental` in their `@tags`
     - The structure of an `experimental` subdirectory mirrors the structure of its parent directory.
     - Select or create an appropriate directory in `experimental` based on the existing directory structure of `experimental` or its parent directory.

-## 0.7.3
-
-### Minor Analysis Improvements
-
-* Deleted the deprecated `hasCopyConstructor` predicate from the `Class` class in `Class.qll`.
-* Deleted many deprecated predicates and classes with uppercase `AST`, `SSA`, `CFG`, `API`, etc. in their names. Use the PascalCased versions instead.
-* Deleted the deprecated `CodeDuplication.qll` file.
-
-## 0.7.2
-
-### New Features
-
-* Added an AST-based interface (`semmle.code.cpp.rangeanalysis.new.RangeAnalysis`) for the relative range analysis library.
-* A new predicate `BarrierGuard::getAnIndirectBarrierNode` has been added to the new dataflow library (`semmle.code.cpp.dataflow.new.DataFlow`) to mark indirect expressions as barrier nodes using the `BarrierGuard` API.
-
-### Major Analysis Improvements
-
-* In the intermediate representation, handling of control flow after non-returning calls has been improved. This should remove false positives in queries that use the intermedite representation or libraries based on it, including the new data flow library.
-
-### Minor Analysis Improvements
-
-* The `StdNamespace` class now also includes all inline namespaces that are children of `std` namespace.
-* The new dataflow (`semmle.code.cpp.dataflow.new.DataFlow`) and taint-tracking libraries (`semmle.code.cpp.dataflow.new.TaintTracking`) now support tracking flow through static local variables.
-
-## 0.7.1
-
-No user-facing changes.
-
-## 0.7.0
-
-### Breaking Changes
-
-* The internal `SsaConsistency` module has been moved from `SSAConstruction` to `SSAConsitency`, and the deprecated `SSAConsistency` module has been removed.
-
-### Deprecated APIs
-
-* The single-parameter predicates `ArrayOrVectorAggregateLiteral.getElementExpr` and `ClassAggregateLiteral.getFieldExpr` have been deprecated in favor of `ArrayOrVectorAggregateLiteral.getAnElementExpr` and `ClassAggregateLiteral.getAFieldExpr`.
-* The recently introduced new data flow and taint tracking APIs have had a
-  number of module and predicate renamings. The old APIs remain in place for
-  now.
-* The `SslContextCallAbstractConfig`, `SslContextCallConfig`, `SslContextCallBannedProtocolConfig`, `SslContextCallTls12ProtocolConfig`, `SslContextCallTls13ProtocolConfig`, `SslContextCallTlsProtocolConfig`, `SslContextFlowsToSetOptionConfig`, `SslOptionConfig` dataflow configurations from `BoostorgAsio` have been deprecated. Please use `SslContextCallConfigSig`, `SslContextCallGlobal`, `SslContextCallFlow`, `SslContextCallBannedProtocolFlow`, `SslContextCallTls12ProtocolFlow`, `SslContextCallTls13ProtocolFlow`, `SslContextCallTlsProtocolFlow`, `SslContextFlowsToSetOptionFlow`.
-
-### New Features
-
-* Added overridable predicates `getSizeExpr` and `getSizeMult` to the `BufferAccess` class (`semmle.code.cpp.security.BufferAccess.qll`). This makes it possible to model a larger class of buffer reads and writes using the library.
-
-### Minor Analysis Improvements
-
-* The `BufferAccess` library (`semmle.code.cpp.security.BufferAccess`) no longer matches buffer accesses inside unevaluated contexts (such as inside `sizeof` or `decltype` expressions). As a result, queries using this library may see fewer false positives.
-
-### Bug Fixes
-
-* Fixed some accidental predicate visibility in the backwards-compatible wrapper for data flow configurations. In particular `DataFlow::hasFlowPath`, `DataFlow::hasFlow`, `DataFlow::hasFlowTo`, and `DataFlow::hasFlowToExpr` were accidentally exposed in a single version.
-
-## 0.6.1
-
-No user-facing changes.
-
-## 0.6.0
-
-### Breaking Changes
-
-* The `semmle.code.cpp.commons.Buffer` and `semmle.code.cpp.commons.NullTermination` libraries no longer expose `semmle.code.cpp.dataflow.DataFlow`. Please import `semmle.code.cpp.dataflow.DataFlow` directly.
-
-### Deprecated APIs
-
-* The `WriteConfig` taint tracking configuration has been deprecated. Please use `WriteFlow`.
-
-### New Features
-
-* Added support for merging two `PathGraph`s via disjoint union to allow results from multiple data flow computations in a single `path-problem` query.
-
-### Major Analysis Improvements
-
-* A new C/C++ dataflow library (`semmle.code.cpp.dataflow.new.DataFlow`) has been added.
-  The new library behaves much more like the dataflow library of other CodeQL supported
-  languages by following use-use dataflow paths instead of def-use dataflow paths.
-  The new library also better supports dataflow through indirections, and new predicates
-  such as `Node::asIndirectExpr` have been added to facilitate working with indirections.
-
-  The `semmle.code.cpp.ir.dataflow.DataFlow` library is now identical to the new
-  `semmle.code.cpp.dataflow.new.DataFlow` library.
-* The main data flow and taint tracking APIs have been changed. The old APIs
-  remain in place for now and translate to the new through a
-  backwards-compatible wrapper. If multiple configurations are in scope
-  simultaneously, then this may affect results slightly. The new API is quite
-  similar to the old, but makes use of a configuration module instead of a
-  configuration class.
-
-### Minor Analysis Improvements
-
-* Deleted the deprecated `hasGeneratedCopyConstructor` and `hasGeneratedCopyAssignmentOperator` predicates from the `Folder` class.
-* Deleted the deprecated `getPath` and `getFolder` predicates from the `XmlFile` class.
-* Deleted the deprecated `getMustlockFunction`, `getTrylockFunction`, `getLockFunction`, and `getUnlockFunction` predicates from the `MutexType` class.
-* Deleted the deprecated `getPosInBasicBlock` predicate from the `SubBasicBlock` class.
-* Deleted the deprecated `getExpr` predicate from the `PointerDereferenceExpr` class.
-* Deleted the deprecated `getUseInstruction` and `getDefinitionInstruction` predicates from the `Operand` class.
-* Deleted the deprecated `isInParameter`, `isInParameterPointer`, and `isInQualifier` predicates from the `FunctionInput` class.
-* Deleted the deprecated `isOutParameterPointer`, `isOutQualifier`, `isOutReturnValue`, and `isOutReturnPointer` predicate from the `FunctionOutput` class.
-* Deleted the deprecated 3-argument `isGuardPhi` predicate from the `RangeSsaDefinition` class.

-### Breaking Changes
-
-The predicates in the `MustFlow::Configuration` class used by the `MustFlow` library (`semmle.code.cpp.ir.dataflow.MustFlow`) have changed to be defined directly in terms of the C++ IR instead of IR dataflow nodes.
-
-### Deprecated APIs
-
-* Deprecated `semmle.code.cpp.ir.dataflow.DefaultTaintTracking`. Use `semmle.code.cpp.ir.dataflow.TaintTracking`.
-* Deprecated `semmle.code.cpp.security.TaintTrackingImpl`. Use `semmle.code.cpp.ir.dataflow.TaintTracking`.
-* Deprecated `semmle.code.cpp.valuenumbering.GlobalValueNumberingImpl`. Use `semmle.code.cpp.valuenumbering.GlobalValueNumbering`, which exposes the same API.
-
-### Minor Analysis Improvements
-
-* The `ArgvSource` flow source now uses the second parameter of `main` as its source instead of the uses of this parameter.
-* The `ArgvSource` flow source has been generalized to handle cases where the argument vector of `main` is not named `argv`.
-* The `getaddrinfo` function is now recognized as a flow source.
-* The `secure_getenv` and `_wgetenv` functions are now recognized as local flow sources.
-* The `scanf` and `fscanf` functions and their variants are now recognized as flow sources.
-* Deleted the deprecated `getName` and `getShortName` predicates from the `Folder` class.

-
-No user-facing changes.
-
-## 0.4.4
-
-No user-facing changes.
-
-## 0.4.3
-
-### Minor Analysis Improvements
-
-* Fixed bugs in the `FormatLiteral` class that were causing `getMaxConvertedLength` and related predicates to return no results when the format literal was `%e`, `%f` or `%g` and an explicit precision was specified.
-
-## 0.4.2
-
-No user-facing changes.
-
-## 0.4.1
-
-No user-facing changes.
-
-## 0.4.0
-
-### Deprecated APIs
-
-* Some classes/modules with upper-case acronyms in their name have been renamed to follow our style-guide. 
-  The old name still exists as a deprecated alias.
-
-### New Features
-
-* Added subclasses of `BuiltInOperations` for `__is_same`, `__is_function`, `__is_layout_compatible`, `__is_pointer_interconvertible_base_of`, `__is_array`, `__array_rank`, `__array_extent`, `__is_arithmetic`, `__is_complete_type`, `__is_compound`, `__is_const`, `__is_floating_point`, `__is_fundamental`, `__is_integral`, `__is_lvalue_reference`, `__is_member_function_pointer`, `__is_member_object_pointer`, `__is_member_pointer`, `__is_object`, `__is_pointer`, `__is_reference`, `__is_rvalue_reference`, `__is_scalar`, `__is_signed`, `__is_unsigned`, `__is_void`, and `__is_volatile`.
-
-### Bug Fixes
-
-* Fixed an issue in the taint tracking analysis where implicit reads were not allowed by default in sinks or additional taint steps that used flow states.
-
-## 0.3.5
-
-## 0.3.4
-
-### Deprecated APIs
-
-* Many classes/predicates/modules with upper-case acronyms in their name have been renamed to follow our style-guide. 
-  The old name still exists as a deprecated alias.
-
-### New Features
-
-* Added support for getting the link targets of global and namespace variables.
-* Added a `BlockAssignExpr` class, which models a `memcpy`-like operation used in compiler generated copy/move constructors and assignment operations.
-
-### Minor Analysis Improvements
-
-* All deprecated predicates/classes/modules that have been deprecated for over a year have been deleted.
-
-## 0.3.3
-
-### New Features
-
-* Added a predicate `getValueConstant` to `AttributeArgument` that yields the argument value as an `Expr` when the value is a constant expression.
-* A new class predicate `MustFlowConfiguration::allowInterproceduralFlow` has been added to the `semmle.code.cpp.ir.dataflow.MustFlow` library. The new predicate can be overridden to disable interprocedural flow.
-* Added subclasses of `BuiltInOperations` for `__builtin_bit_cast`, `__builtin_shuffle`, `__has_unique_object_representations`, `__is_aggregate`, and `__is_assignable`.
-
-### Major Analysis Improvements
-
-* The IR dataflow library now includes flow through global variables. This enables new findings in many scenarios.
-
-## 0.3.2
-
-### Bug Fixes
-
-* Under certain circumstances a variable declaration that is not also a definition could be associated with a `Variable` that did not have the definition as a `VariableDeclarationEntry`. This is now fixed, and a unique `Variable` will exist that has both the declaration and the definition as a `VariableDeclarationEntry`.
-
-## 0.3.1
-
-### Minor Analysis Improvements
-
-* `AnalysedExpr::isNullCheck` and `AnalysedExpr::isValidCheck` have been updated to handle variable accesses on the left-hand side of the C++ logical "and", and variable declarations in conditions.
-
-## 0.3.0
-
-### Deprecated APIs
-
-* The `BarrierGuard` class has been deprecated. Such barriers and sanitizers can now instead be created using the new `BarrierGuard` parameterized module.
-
-### Bug Fixes
-
-* `UserType.getADeclarationEntry()` now yields all forward declarations when the user type is a `class`, `struct`, or `union`.
-
-## 0.2.3
-
-### New Features
-
-* An `isBraced` predicate was added to the `Initializer` class which holds when a C++ braced initializer was used in the initialization.
-
-## 0.2.2
-
-### Deprecated APIs
-
- * The `AnalysedString` class in the `StringAnalysis` module has been replaced with `AnalyzedString`, to follow our style guide. The old name still exists as a deprecated alias.
-
-### New Features
-
-* A `getInitialization` predicate was added to the `ConstexprIfStmt`, `IfStmt`, and `SwitchStmt` classes that yields the C++17-style initializer of the `if` or `switch` statement when it exists.
-
-## 0.2.1
-
-## 0.2.0
-
-### Breaking Changes
-
-* The signature of `allowImplicitRead` on `DataFlow::Configuration` and `TaintTracking::Configuration` has changed from `allowImplicitRead(DataFlow::Node node, DataFlow::Content c)` to `allowImplicitRead(DataFlow::Node node, DataFlow::ContentSet c)`.
-
-### Minor Analysis Improvements
-
-* More Windows pool allocation functions are now detected as `AllocationFunction`s.
-* The `semmle.code.cpp.commons.Buffer` library has been enhanced to handle array members of classes that do not specify a size.
-
-## 0.1.0
-
-### Breaking Changes
-
-* The recently added flow-state versions of `isBarrierIn`, `isBarrierOut`, `isSanitizerIn`, and `isSanitizerOut` in the data flow and taint tracking libraries have been removed.
-
-### New Features
-
-* A new library `semmle.code.cpp.security.PrivateData` has been added. The new library heuristically detects variables and functions dealing with sensitive private data, such as e-mail addresses and credit card numbers.
-
-### Minor Analysis Improvements
-
-* The `semmle.code.cpp.security.SensitiveExprs` library has been enhanced with some additional rules for detecting credentials.
-
-## 0.0.13
-
-## 0.0.12
-
-### Breaking Changes
-
-* The flow state variants of `isBarrier` and `isAdditionalFlowStep` are no longer exposed in the taint tracking library. The `isSanitizer` and `isAdditionalTaintStep` predicates should be used instead.
-
-### Deprecated APIs
-
-* Many classes/predicates/modules that had upper-case acronyms have been renamed to follow our style-guide. 
-  The old name still exists as a deprecated alias.
-
-### New Features
-
-* The data flow and taint tracking libraries have been extended with versions of `isBarrierIn`, `isBarrierOut`, and `isBarrierGuard`, respectively `isSanitizerIn`, `isSanitizerOut`, and `isSanitizerGuard`, that support flow states.
-
-### Minor Analysis Improvements
-
-* `DefaultOptions::exits` now holds for C11 functions with the `_Noreturn` or `noreturn` specifier.
-* `hasImplicitCopyConstructor` and `hasImplicitCopyAssignmentOperator` now correctly handle implicitly-deleted operators in templates.
-* All deprecated predicates/classes/modules that have been deprecated for over a year have been deleted.
-
-## 0.0.11
-
-### Minor Analysis Improvements
-
-* Many queries now support structured bindings, as structured bindings are now handled in the IR translation.
-
-## 0.0.10
-
-### New Features
-
-* Added a `isStructuredBinding` predicate to the `Variable` class which holds when the variable is declared as part of a structured binding declaration.
-
-## 0.0.9
