umzug 3.0.0-beta.1 on Node.js NPM

Removed the deprecated storage aliases: none, json and sequelize. To upgrade: just use Storage, JsonStorage and SequelizeStorage instead.
Removed the upName and downName options, which allowed you to have migrations whose exported functions had custom names (not just up and down). To upgrade: stop using this option and either rename the functions in your migrations to up and down or use the wrap option (or customResolver option) to change that automatically before umzug reads it.
