@@ -71,6 +71,15 @@ Versions follow `MAJOR.MINOR.PATCH-REVISION_STAGE_N` (e.g. `3.99.1-4_rc_1`).
   `busy` documented in its usage now works; `grep`/`read` no longer mangle
   patterns starting with `-` or lines with leading blanks; `awk` is no longer
   forked for each pause.
+- `git.sh`: `gprune --deep` never deleted anything (`<branch>@{upstream}` fails
+  once the remote branch is gone; it now reads the configured upstream ref);
+  `gprune` returned 1 on success and could not be told which branches are
+  protected (`GIT_MAIN_BRANCH` is now honoured); `greset` stashed the local
+  changes before checking that the target exists, ignored untracked files
+  outside the current directory and cleaned only below it; `gsync` could fetch
+  a different remote than the one it rebased on; `gacp`/`gsync` handle remote
+  and branch names containing slashes, and refuse a detached HEAD; `ggraph`
+  rejects a limit of 0; internal helpers are exported with the commands.
 - `compress.sh`: option flags and loop variables no longer leak into the
   interactive shell.
