 | `conf_save` | conf | Save or update a key=value pair in a configuration section: `conf_save <section> <key> <value>`; replaces an existing key in place or appends it to the section (creating the section if absent); works through a symlinked file and keeps its permissions; the value must be single-line and the running shell is not updated (applies at next load) |
 | `disp` | disp | Display formatted info / warning / error / debug messages; long messages are word-wrapped and continuation lines are indented to align with the message text; honours `NO_COLOR`, `QUIET=1` (hides info messages) and `DEBUG` > 1 (shows debug messages); warnings, errors and debug go to stderr |
 | `dwl` | net | Download a URL using curl, wget, or fetch transparently; supports `-t <seconds>` / `--timeout <seconds>` to cap the transfer time |
-| `expandlist` | filefct | Expand glob expressions into a quoted, separated list |
+| `expandlist` | filefct | Expand glob expressions into a quoted, separated list; names with spaces are kept whole, `\`, `"`, `$` and `` ` `` are escaped, and the separator (`-s`, `-n` or `EXPANDLIST_DEFAULT_SEPARATOR`) may use escapes such as `\n` |
 | `fake_compile` | fun | Simulate a long compilation process with random warnings and errors |
-| `file_stats` | filefct | Display file size statistics for a path |

-| `findzero` | filefct | Find empty files in the given or current directory |
+| `findzero` | filefct | Find empty files in the given or current directory; `--delete` does not follow symlinks |
 | `gacp` | git | Add, commit and push changes; auto-pulls with rebase first if needed |
 | `genpwd` | pwd | Generate one or more random secure passwords with configurable constraints |
 | `ggraph` | git | Display a decorated git history graph |

   `\_`-style escapes are protected from emphasis/link parsing; `NO_COLOR` is
   honoured in tables and headings; fewer subprocesses when rendering tables;
   newlines in arguments no longer break option parsing.
+- `filefct.sh`: `findzero` with `fd` listed (and `--delete` removed) one-byte
+  files; `findzero --delete` could remove symlinks to empty files; `rmspc`
+  overwrote existing files, passed a wrong replacement character to
+  subdirectories with `-r -c X`, followed symlinked directories and mishandled
+  `&` as replacement; `expandlist` split names containing spaces, ignored `\n` in
+  its separator and reset the caller's `nullglob`; `file_stats` histogram was
+  unordered, `--min` was exclusive and invalid sizes silently gave no result;
+  `findbig` accepted an invalid configured limit; names starting with `-` are
+  handled; `finddead` and `findzero` no longer return 1 when the last entry
+  was skipped.
 - `compress.sh`: option flags and loop variables no longer leak into the
   interactive shell.
