+# LLVM dependency supports both dynamic and static linking
+
+The LLVM dependency has been improved to consistently use dynamic linking.
+Previously recent version (>= 3.9) would link dynamically while older versions
+would link statically.
+
+Now LLVM also accepts the `static` keyword to enable statically linking to LLVM
+modules instead of dynamically linking.
