    - DATE, TIME and DATETIME types can now take optional storage_format and
      regexp argument. storage_format can be used to store those types using
      a custom string format. regexp allows to use a custom regular expression
      to match string values from the database.
    - Time and DateTime types now use by a default a stricter regular
      expression to match strings from the database. Use the regexp argument
      if you are using data stored in a legacy format.
    - __legacy_microseconds__ on SQLite Time and DateTime types is not
      supported anymore. You should use the storage_format argument instead.
    - Date, Time and DateTime types are now stricter in what they accept as
      bind parameters: Date type only accepts date objects (and datetime ones,
      because they inherit from date), Time only accepts time objects, and
      DateTime only accepts date and datetime objects.
