dhall-1.9.0

• Feature: BREAKING CHANGE TO LANGUAGE AND API: Add constructors keyword
  • This new keyword generates constructors from a union type
    • See the updated Haskell tutorial for more details
  • This means that constructors is now a reserved keyword
  • This adds a new Constructors constructor to the Expr type
  • See: #199
• Feature: BREAKING CHANGE TO THE API: dhall-format preserves interpolation
  • This changes the TextLit constructor to represent an interpolated Text
    literal
  • See: #220
• Feature: You can now define type synonyms using let
  • See: #202
• Feature: Extend valid set of quoted labels
  • See: dhall-lang/dhall-lang#65
  • See: dhall-lang/dhall-lang#77
• Performance: Improve startup time when importing files, but not URLs
  • See: #194
• Security: localhost/127.0.0.1 imports no longer count as local imports
  • Specifically: they cannot import environment variables or files
  • See: #197
• Security: Fix potential type-checking bug
  • See: #198
• Fix: BREAKING CHANGE TO API: Improve localization of error messages
  • This required fixing the type of normalize/shift/subst to preserve
    the first type parameter of Expr (i.e. they no longer delete Note
    constructors)
  • A new denote function was added for the explicit purpose of deleting
    Note constructors
  • See: #218
• Expose MissingEnvironmentVariable exception type
  • See: #196
• Add genericAuto
  • See: #195
• Add inputWith
  • See: #222
• AddloadWithContext
  • See: #215
• Add pair/unit/string/list
  • See: #227
