Everything needed to run a comprehensive dev environment.
Just type X_ and pick a service from autocomplete;
new dev modules will be added as they are built.
The only dev service not included in the uber jar is xapi-dev-maven,
as it includes all runtime dependencies of maven, adding ~4 seconds to build time,
and 6 megabytes to the final output jar size (without xapi-dev-maven, it's ~1MB).
The newest version!
