+## 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
