devtools 2.4.4

• install(reload = TRUE) now calls pkgload::unregister() instead
  of pkload::unload() (#2349). This allows the package to keep
  functioning if it is still in use in the R session (e.g. through
  event handlers).

• test() no longer calls load_all() twice. test_active_file()
  now calls load_all() via testthat.

• aspell_env_var() does a better job of matching R CMD check behaviour,
  which is only to use aspell, not hunspell or ispell (#2376).

• Installing devtools now installs pkgdown, profvis, bench, miniUI,
  and urlchecker, ensuring that you have everything needed for package
  development (#2388).

• dev_sitrep() has been updated for the calendar-based version number scheme
  adopted by the RStudio IDE in September 2021 (#2397, #2410).
