-## 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.

-### 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.

-
-* 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`.

-## 0.3.3
-
-### 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.

-
-### 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.
