Log Message:
lang/dhall: Update to 1.42.1

1.42.1

    Add several new entrypoints to Dhall module [#2534] / [#2544]

    Build against latest versions of:
        ansi-terminal
        optparse-applicative
        optparse-generic
        lens
        template-haskell [#2532] / [#2542]
        unix-compat 1.42.0

    Supports standard version 23.0.0
        BREAKING CHANGE TO THE API AND LANGUAGE: Language support for Bytes literals
            This is a breaking change to the API due to adding new Bytes and \ 
BytesLiteral constructors to the Expr type
            This is a breaking change to the language now that Bytes is a \ 
reserved identifier
        BREAKING CHANGE TO THE API AND LANGUAGE: New {Date,Time,TimeZone}/show \ 
builtins
            This is a breaking change to the API due to adding new \ 
{Date,Time,TimeZone}Show constructors to the Expr type
            This is a breaking change to the language now that \ 
{Date,Time,TimeZone}/show are not reserved identifiers

    BREAKING CHANGE: dhall lint no longer sorts let bindings
        This had to be removed because the old behavior was not always correct
        The old behavior would sometimes change the behavior of a Dhall program \ 
or break the program
        Out of an abundance of caution we're disabling the feature until it can \ 
be properly fixed (which is't trivial)

    BUG FIX: Fix pretty-printing of Time literals
        The pretty-printer was stripping leading zeros from the fractional \ 
component of seconds

    BUG FIX: Fix custom normalizers to work for things other than functions
        Before this change you could extend the language with custom functions, \ 
but not custom values (e.g. foo = 1)

    BUG FIX: Don't URL encode path components
        The pretty-printer was URL-encoding path components, which is not \ 
correct (according to the standard)
        URL path components are supposed to be already URL-encoded by the user \ 
and left undisturbed by the interpreter (which is now what it correctly does)

    New dhall package command: #2478, #2508
        This command makes it easier to turn a directory full of Dhall \ 
expressions into a dhall package (e.g. package.dhall)

    Improved dhall to-directory-tree subcommand
        The dhall to-directory-tree subcommand now optionally supports \ 
specifying metadata for generated paths
        For a worked example, see: \ 
https://github.com/dhall-lang/dhall-haskell/blob/main/dhall/examples/to-directory-tree.dhall

    dhall freeze --cache --all is now idempotent: #2486, #2500
        Before this change a second run would fail due to attempting to resolve \ 
the missing import it would generate

    New Template Haskell options for adding strictness annotations to generated \ 
Haskell types

    Template Haskell can now generate higher-kinded Haskell types from \ 
higher-kinded Dhall types

    New Dhall.Freeze utilities for working with custom evaluators

    Add Data instances for Import and various other types

    Add Eq instances for InvalidDecoder and ExtractError
