   leaked a variable.
 - `packages.sh`: `pkgf ls` now looks the command up in the `PATH`; `pkgs`
   accepts patterns starting with `-`; `suse` is recognised in `ID_LIKE`.
+- `processes.sh`: `ku -9 user` / `kt -KILL pid` were rejected by option parsing
+  although documented (kill-style signals are now extracted before `getopt`);
+  `ku` accepts numeric user IDs (killall only takes names), checks all users
+  before killing, returns a failure status when a kill fails, and refuses
+  root and the current user; `kt` no longer re-parses its options for each
+  child, validates the PID and refuses the current shell; `ppn` matched PIDs
+  and names such as `kde-bash` (now exact); `ppg`/`gpid` fallbacks no longer
+  match their own `awk`; `PPU_DEFAULT_FORMAT` documented with its real value.
 - `compress.sh`: option flags and loop variables no longer leak into the
   interactive shell.
