			# 1.0.0 -> 2.0.0
			The option `nodeFlags` was renamed to `v8flags` for accuracy. It can now be a callback taking method that yields an array of flags, or an array literal.

			# 0.11 -> 0.12
			For the environment passed into the `launch` callback, `configNameRegex` has been renamed to `configNameSearch`. It now returns an array of valid config names instead of a regular expression.

			# 0.10 -> 0.11
			The method signature for `launch` was changed in this version of Liftoff.

			You must now provide your own options parser and pass your desired params directly into `launch` as the first argument. The second argument is now the invocation callback that starts your application.

			To replicate the default functionality of 0.10, use the following:
			```js
			const Liftoff = require('liftoff');
			const MyApp = new Liftoff({name:'myapp'});
			const argv = require('minimist')(process.argv.slice(2));
			const invoke = function (env) {
			console.log('my environment is:', env);
			console.log('my cli options are:', argv);
			console.log('my liftoff config is:', this);
			};
			MyApp.launch({
			cwd: argv.cwd,
			configPath: argv.myappfile,
			require: argv.require,
			completion: argv.completion
			}, invoke);
			```
