 - Fixed `--with-shell` on Windows not detecting cmd, PowerShell, and pwsh, which made fzf quote commands and entries for a POSIX shell (#4936) (@vimkim)
     - e.g. With `--with-shell "cmd.exe /d /c"`, `--preview '"C:\Program Files\nu\bin\nu.exe" --version'` failed
 - `transform-nth` and `transform-with-nth` (and their `bg-` variants) no longer split the output at `|`

+- Fixed `--no-sort` being ignored in filter mode with `--sync`, `--tac`, or `--bench` (#4940) (@NavpreetSSidhu)
