6.0.0 (2020-09-30)

Features

• API: Add 4 cities instead of 2 in formatting and data (952aeb5)
• data: Automatic data update (dc2bb99)

BREAKING CHANGES

• API: The data now contains 4 cities instead of 2 for each time zone.
  This change was made because some important cities are sometimes not the most
  populated (San Francisco for example).
