-# A =import= definition TODO
-TBA
+Through the =import= definition it is possible to load external specifications and modules into the specification.
+The provided identifier path is used to search inside the specification base path for the requested specification.
+If the imported specification does belong to an external module, the import has to be defined externally via a CASM project YAML file.
+By default, if no import renaming (=as= identifier) is specified, the last identifier in the given import path is used.

+This is the fourth official release of the CASM project.
+It introduces three improvements.
+It introduces three improvements and this time all improvements are language related.
+First, we have a module and import system for our language. Through a new =import= syntax it is possible to load external specifications and modules into the current specification.
+Second, the CASM language allows UTF-8 symbols in comments, string literals, and certain characters for identifier names. 
+Last but not least, we changed the =init= definition to be optional in CASM specifications to support =import= only specifications as well.
