… instead of Object so client code can avoid type casting.

 - #179 API Change to remove full JRE dependency and require only Compact Profile. Replace use of `java.awt.Point` with `picocli.CommandLine.Help.TextTable.Cell`. Thanks to [webfolderio](https://github.com/webfolderio).
 - #196 API Change: `Option::type()` and `Parameters::type()` now return empty array by default (was `{String.class}`).
+- #205 API Change: `CommandLine::getCommand` now returns a generic type instead of Object so client code can avoid type casting.
 - #130 New feature: Options and positional parameters can now be mixed on the command line.
 - #196 New feature: Infer type from collections and maps when `type` annotation not specified. Thanks to [ddimtirov](https://github.com/ddimtirov) for the suggestion.
 - #197 New feature: Use `type` attribute to determine conversion target type instead of field type. This allows fields to be declared as interfaces or abstract types (or arrays/collections/maps of these) and via the `type` attribute picocli will be able to convert String arguments to concrete implementation objects.
