v4.0.0

4.0.0 (2024-01-25)

⚠ BREAKING CHANGES

• Date objects now have a type
  discriminator, in the form of a "type" field, which
  is always set to the string "Date". The isDate and
  isValidDate functions will not consider a value to
  be a Date unless the discriminator is present. Most
  other functions continue to accept objects without
  this field, but if it is present it must be set to
  the string "Date". This is to guard against errors
  caused by similar objects such as DateTimes or
  Timestamps being accidentally passed to date
  functions. The type discriminator also makes it easy
  to discriminate Dates from other types in type
  unions.
• node: node versions < 18, 19 are no longer
  supported.
