Release v1.21.0 · sharkdp/hyperfine

Features

Add support for minutes and hours in --time-unit, as well as short and plural aliases such as ms, seconds, and min, see #960 (@sharkdp)
Expose $HYPERFINE_ITERATION to --prepare and --conclude commands, see #781 and #807 (@willcl-ark)
Show elapsed time during the initial benchmark run, see #416 and #581 (@devonhollowood)
Add colors to --help output, see #841 (@starsep)

With --parameter-scan or --parameter-list, --reference now selects an existing benchmark by its full displayed name instead of running a separate reference command. The name must match exactly one benchmark; use --command-name instead of --reference-name in this mode, see #847 and #979 (@sharkdp)
Format times in CSV exports with six decimal places, see #966 and #972 (@sharkdp)
Update dependencies and raise the minimum supported Rust version to 1.97, see #934 (@sharkdp)

Make Markdown, AsciiDoc, and Org-mode exports compare against the specified reference, and label faster and slower results in command-sorted comparisons with --reference, see #811 and #979 (@sharkdp)
Reject zero values for --runs, --min-runs, and --max-runs instead of allowing invalid run counts, see #923 (@VXNCXNX, @sharkdp)
Reject negative parameter-scan steps before expanding ranges, avoiding hangs and excessive memory use, see #951 (@Likio3000)
Preserve existing export files when command options are invalid, see #950 (@Likio3000)
Truncate export files when rewriting results to avoid leaving trailing bytes, see #970 (@sharkdp)
Preserve backticks in command names in Markdown exports, see #947 (@Likio3000)
Handle broken output pipes gracefully instead of panicking, see #932 (@Mathjk)
Collect peak memory usage separately for each command on Unix, so commands no longer inherit the peak memory usage of earlier commands, see #965 (@sharkdp)
Preserve 100-nanosecond precision in Windows CPU times, see #964 (@sharkdp)
Python scripts: Correct the interpretation of Welch's t-test results, see #943 (@sharkdp)

Build binaries for Windows ARM64 and Linux ARM64 musl, see #922 and #924 (@meop)
Refactor measurement, statistics, and formatting code to use typed quantities, see #954, #958, #961, #967, #969, #971, and #976 (@sharkdp)
Improve documentation and examples, including comparisons across Git branches, iteration variables, reference commands, and selective failure handling, see #899, #900, #929, and #940 (@xfocus3, @ded-furby, @Likio3000, @sharkdp)
