1.41.0

• Support standard version 22.0.0
  • Allow with expressions to update Optional values using ?
  • Add showConstructor keyword
• BUG FIX: Fix pretty-printing of time zones
  • Timezones with a negative offset were previously being rendered with two
    leading minus signs instead of one
• BUG FIX: dhall freeze --cache to work with standard version 21.0.0
  • dhall freeze will now use missing sha256:… for the first import so that
    the latter import will be tried if the import is not in cache
  • The old behavior is incompatible with standard version 21.0.0 because the
    new behavior of the ? operator doesn't fall back on hash mismatches
• BUG FIX: Allow with expression to update a field named Some
  • This fixes a discrepancy between the Haskell implementation and the standard
    where the Haskell implementation would not permit
    { Some = 0 } with Some = 1
• Fix dhall {format,lint,freeze} to preserve leading shebangs
• Add FromDhall instances for Int{8,16,32,64}
