+## 1.4.3
+
+This release moves to using a new syntax (`::`) to separate the key and value portions of a map definition in the maps file. Backwards compatibility is maintained for the existing `:` syntax, but this has been deprecated and should not be used. Please update any existing map configurations to use the new syntax.
+
+This release also adds additional validation to catch errors associated with specifying a registry in a map definition key that includes the `:<port_number>` syntax. Previously this would result in an error and a stack trace. This is now handled gracefully and the new map separator syntax should allow for registries to include ports going forward.
