 ### Added
 
+- `pkgi` (install) and `pkgr` (uninstall, with `-p`/`--purge` and `-d`/`--deps`)
+  commands for apt, dnf/yum, zypper, pacman, apk, portage, xbps and nix; both
+  accept `-y`/`--yes` and `-n`/`--dry-run` and use `sudo` (or `doas`) when needed.
 - `utaz -i` / `--ignore-case` and `-s` / `--case-sensitive` switches to match
   archive extensions case-insensitively or not; the default is set by the new
   `UTAZ_DEFAULT_IGNORE_CASE` key of the `[compress]` section (default `0`).

 - `compress.sh`: option flags and loop variables no longer leak into the
   interactive shell.
