 Pinning an action to a full length commit SHA is currently the only way to use a non-immutable action as an immutable release.

+## 5.4.0
+
+### New Features
+
+* Exposed various SSA-related classes (`Definition`, `PhiNode`, `ExplicitDefinition`, `DirectExplicitDefinition`, and `IndirectExplicitDefinition`) which were previously only usable inside the internal dataflow directory.
+
+### Minor Analysis Improvements
+
+* The `cpp/overrun-write` query now recognizes more bound checks and thus produces fewer false positives.
+
+## 5.3.0
+
+### Deprecated APIs
+
+* The `UnknownDefaultLocation`, `UnknownExprLocation`, and `UnknownStmtLocation` classes have been deprecated. Use `UnknownLocation` instead.
+
+### New Features
+
+* Added a `isFinalValueOfParameter` predicate to `DataFlow::Node` which holds when a dataflow node represents the final value of an output parameter of a function.
+
+### Minor Analysis Improvements
+
+* The `FunctionWithWrappers` library (`semmle.code.cpp.security.FunctionWithWrappers`) no longer considers calls through function pointers as wrapper functions.
+* The analysis of C/C++ code targeting 64-bit Arm platforms has been improved. This includes support for the Arm-specific builtin functions, support for the `arm_neon.h` header and Neon vector types, and support for the `fp8` scalar type. The `arm_sve.h` header and scalable vectors are only partially supported at this point.
+* Added support for `__fp16 _Complex` and `__bf16 _Complex` types
+* Added `sql-injection` sink models for the Oracle Call Interface (OCI) database library functions `OCIStmtPrepare` and `OCIStmtPrepare2`.
