v0.1.0

This is the first public release of LiveLoad.

For the full development journey (and basically my personal development diary) from an empty repo to this release, see the Devlog.

If you are just getting started with LiveLoad, the Writing Your First Scenario guide is the best place to start. It covers everything from basic navigation to throttles, assigns, and the full scenario lifecycle.
