v1.13.0

Features

• Added a new --shell=none/-N option to disable the intermediate
  shell for executing the benchmarked commands. Hyperfine normally
  measures and subtracts the shell spawning time, but the intermediate
  shell always introduces a certain level of measurement noise. Using
  --shell=none/-N allows users to benchmark very fast commands
  (with a runtime on the order of a few milliseconds). See #336, #429,
  and #487 (@cipriancraciun and @sharkdp)
• Added --setup/-s option that can be used to run make all or
  similar. It runs once per set of tests, like --cleanup/-c (@avar)
• Added new plot_progression.py script to debug background
  interference effects.

Changes

• Breaking change: the -s short option for --style is now used for
  the new --setup option.
• The environment offset randomization is now also available on Windows,
  see #484

Other

• Improved documentation and test coverage, cleaned up code base for
  future improvements.
