Migration from 5.x to 6.0.0 should be smooth. Change any instance of
env.get(target, default) to env.get(target).default(default). For example:

// Old 5.x code
const emailAddr = env.get('EMAIL_ADDR', '[email protected]').asString()

// New 6.x compatible code
const emailAddr = env.get('EMAIL_ADDR').default('[email protected]').asString()
