+## 10.2.0
+
+### Deprecated APIs
+
+* The `UsingAliasTypedefType` class has been deprecated. Use `TypeAliasType` instead.
+
+### New Features
+
+* Added a `getOriginalTemplate` predicate to `TemplateClass`, `TemplateFunction`, `TemplateVariable`, and `AliasTemplateType`, which yields the class member template the template was generated from. The predicates only have results for templates that are members of class template instantiations.
+* Added `AliasTemplateType` and `AliasTemplateInstantiationType` classes, representing C++ alias templates and their instantiations.
+
+### Minor Analysis Improvements
+
+* Added flow source models for `scanf_s` and related functions.
+* Added a `Call` column to `LocalFlowSourceFunction::hasLocalFlowSource` and `RemoteFlowSourceFunction::hasRemoteFlowSource`. The old predicates without a `Call` column continue to be supported.
