    Changes for jq:

    Update to version 1.7.1:

     * Make the default background color more suitable for bright      backgrounds.
     * Allow passing the inline jq script after --.
     * Fix possible uninitialised value dereference if jq_init() fails
     * Simplify paths/0 and paths/1.
     * Reject U+001F in string literals.
     * Remove unused nref accumulator in block_bind_library.
     * Remove a bunch of unused variables, and useless assignments.
     * main.c: Remove unused EXIT_STATUS_EXACT option.
     * Actually use the number correctly casted from double to int as      index.
     * src/builtin.c: remove unnecessary jv_copy-s in      type_error/type_error2.
     * Remove undefined behavior caught by LLVM 10 UBSAN.
     * Convert decnum to binary64 (double) instead of decimal64.
     This makes jq behave like the JSON specification suggests and      more similar to other languages.
     * Fix memory leaks on invalid input for ltrimstr/1 and      rtrimstr/1.
     * Fix memory leak on failed get for setpath/2.
     * Fix nan from json parsing also for nans with payload that      start with 'n'.
     * Allow carriage return characters in comments.
     * Generate links in the man page.
     * Add extern C for C++.
     * Make object key color configurable using JQ_COLORS environment      variable.
     * Change the default color of null to Bright Black.
     * Respect NO_COLOR environment variable to disable color output.
     * Improved --help output. Now mentions all options and nicer      order.
     * Fix multiple issues of exit code using --exit-code/-e option.
     * Add --raw-output0 for NUL (zero byte) separated output.
     * Fix assert crash and validate JSON for --jsonarg.
     * Remove deprecated --argfile option.
     * Use decimal number literals to preserve precision. Comparison      operations respects precision but arithmetic operations might      truncate.
     * Adds new builtin pick(stream) to emit a projection of the      input object or array.
     * Adds new builtin debug(msgs) that works like debug but applies      a filter on the input before writing to stderr.
     * Adds new builtin scan($re; $flags). Was documented but not      implemented.
     * Adds new builtin abs to get absolute value. This potentially      allows the literal value of numbers to be preserved as length      and fabs convert to float.
     * Allow if without else-branch. When skipped the else-branch      will be . (identity).
     * Allow use of $binding as key in object literals.
     * Allow dot between chained indexes when using .['index']
     * Allow dot for chained value iterator .[], .[]?
     * Fix try/catch catches more than it should.
     * Speed up and refactor some builtins, also remove      scalars_or_empty/0.
     * Now halt and halt_error exit immediately instead of continuing      to the next input.
     * Fix issue converting string to number after previous convert      error.
     * Fix issue representing large numbers on some platforms causing      invalid JSON output.
     * Fix deletion using assigning empty against arrays.
     * Allow keywords to be used as binding name in more places.
     * Allow using nan as NaN in JSON.
     * Expose a module's function names in modulemeta.
     * Fix contains/1 to handle strings with NUL.
     * Fix stderr/0 to output raw text without any decoration.
     * Fix nth/2 to emit empty on index out of range.
     * Fix implode to not assert and instead replace invalid unicode      codepoints.
     * Fix indices/1 and rindex/1 in case of overlapping matches in      strings.
     * Fix sub/3 to resolve issues involving global search-and-replace      (gsub) operations.
     * Fix empty regular expression matches.
     * Fix overflow exception of the modulo operator.
     * Fix string multiplication by 0 (and less than 1) to emit empty      string.
     * Fix segfault when using libjq and threads.
     * Fix constant folding of division and reminder with zero      divisor.
     * Fix error/0, error/1 to throw null error.
     * Simpler and faster transpose.
     * Simple and efficient implementation of walk/1.
     * Remove deprecated filters leaf_paths, recurse_down.
