-## 0.12.8
-
-No user-facing changes.
-
-## 0.12.7
-
-### Minor Analysis Improvements
-
-* Added destructors for named objects to the intermediate representation.
-
-## 0.12.6
-
-### New Features
-
-* A `getInitialization` predicate was added to the `RangeBasedForStmt` class that yields the C++20-style initializer of the range-based `for` statement when it exists.
-
-## 0.12.5
-
-### New Features
-
-* Added the `PreprocBlock.qll` library to this repository.  This library offers a view of `#if`, `#elif`, `#else` and similar directives as a tree with navigable parent-child relationships.
-* Added a new `ThrowingFunction` abstract class that can be used to model an external function that may throw an exception.
-
-## 0.12.4
-
-### Minor Analysis Improvements
-
-* Deleted many deprecated predicates and classes with uppercase `XML`, `SSA`, `SAL`, `SQL`, etc. in their names. Use the PascalCased versions instead.
-* Deleted the deprecated `StrcatFunction` class, use `semmle.code.cpp.models.implementations.Strcat.qll` instead.
-
-## 0.12.3
-
-### Deprecated APIs
-
-* The `isUserInput`, `userInputArgument`, and `userInputReturned` predicates from `SecurityOptions` have been deprecated. Use `FlowSource` instead.
-
-### New Features
-
-* `UserDefineLiteral` and `DeductionGuide` classes have been added, representing C++11 user defined literals and C++17 deduction guides.
-
-### Minor Analysis Improvements
-
-* Changed the output of `Node.toString` to better reflect how many indirections a given dataflow node has.
-* Added a new predicate `Node.asDefinition` on `DataFlow::Node`s for selecting the dataflow node corresponding to a particular definition.
-* The deprecated `DefaultTaintTracking` library has been removed.
-* The `Guards` library has been replaced with the API-compatible `IRGuards` implementation, which has better precision in some cases.
-
-### Bug Fixes
-
-* Under certain circumstances a function declaration that is not also a definition could be associated with a `Function` that did not have the definition as a `FunctionDeclarationEntry`. This is now fixed when only one definition exists, and a unique `Function` will exist that has both the declaration and the definition as a `FunctionDeclarationEntry`.
-
 ## 0.12.2
