+Lorenz 0.4.4
+============
+
+Lorenz 0.4.4 is the combination of bugs identified in the development of Lorenz 0.5.0, specifically
+with regards to the mapping format implementations, in addition to a faulty mapping model method.
+
+## IO
+
+- TSRG: Don't write empty class line for parents
+- TSRG: Correct a length check, preventing some **valid** mappings from being read
+- Enigma: Output field types properly, using the *obfuscated* type
+
+## Mapping Model
+
+- Fix the faulty implementation of `ClassMapping::hasMappings`, specifically it did'nt consider method
+  argument mappings
