1.39.0

• Supports version 20.2.0 of the standard
  • Add support for Unix shebangs
• BREAKING CHANGE TO THE API: dhall {format,freeze,lint} now accept multiple
  files
  • The --inplace flag is no longer necessary and you can now specify
    multiple files to update in place on the command line, like
    dhall format foo.dhall bar.dhall
  • The --inplace flag is still accepted, but does nothing, and will emit a
    warning
  • This is a breaking change to the API for formatting/freezing/linting files
    because now you can specify multiple inputs instead of one input
• BREAKING CHANGE: Pre-6.0.0 hashes are no longer supported
  • The interpreter no longer provides backwards compatibility for integrity
    checks computed before standard version 6.0.0
  • This is a breaking change to the API of the Dhall.Binary module, where
    certain utilities are no longer parameterized on a StandardVersion
  • This is also a breaking change to any Dhall code that depended on these
    really old integrity checks
• BUG FIX: Formatting ≡ now correctly preserves the original character set
• BUG FIX: Don't panic on Text/replace ""
• Quasiquotation support for Dhall
  • You can now convert a Dhall expression to the corresponding syntax tree
    using a quasiquoter like this: [dhall| \x -> x + 2 ]
• New Dhall.Marshal.{Encode,Decode} modules
  • These modules split up the Dhall module into two smaller modules for
    encoding and decoding logic, respectively
  • The Dhall module still re-exports the same functionality as before, so
    this is not a breaking change
• Support GHC 9.0.1
• Fixes and improvements to code formatting
  • Improve pretty-printing of sha256
