+
+### Fixed
+- **`prompt.sh`** — `\$Last_Command` in PS1 was escaped, preventing the exit
+  code from ever appearing in the prompt (the local variable no longer exists
+  when PS1 is rendered by bash). Removed the backslash so the value is embedded
+  at `set_prompt` build time.
+- **`filefct.sh` — `file_stats()`** — a stray unconditional `shift` after
+  `esac` doubled-shifted arguments already shifted by each `case` branch;
+  successive options such as `-H -d` were silently skipped.
+- **`packages.sh` — `pkgs()`** — replaced the unreliable binary-presence test
+  (`command -v dpkg / rpm`) with the new `get_pkgmgr` function. Also corrected
+  a typo in the "no package manager" error message (`avialable` → `available`).
+- **`processes.sh` — `kt()`** — copy-paste error: usage error message read
+  `"Usage: ppg <string>"` instead of `"Usage: kt <pid>"`.
+
+### Added
+- **`packages.sh` — `get_pkgmgr()`** — new exported helper that detects the
+  active package manager of the running distribution. Detection first reads
+  `/etc/os-release` (`ID` then `ID_LIKE`), then falls back to a
+  fixed-priority binary scan. Supported families: `apt`, `dnf`, `yum`,
+  `zypper`, `pacman`, `apk`, `portage`, `xbps`, `nix`. Returns 1 when
+  nothing is identified. Available to all future commands in `packages.sh`.

-## 3. Development environment
+## 3. Branch policy
 
-| Requirement | Minimum version | Notes |
+| Branch | Purpose |
+|---|---|
+| `master` | Main development branch — new features and enhancements go here |
+| `<version>` (e.g. `3.x`) | Maintenance branch for a released version — bugfixes backported from `master` |
+
+**New functionality** must always target `master`.
+
+**Bugfixes** must target the branch where the bug was introduced:
+- If the bug exists in a released version, open the fix against that version's
+  maintenance branch first, then cherry-pick onto `master`.
+- If the bug is only in `master` (unreleased), fix it directly on `master`.
+- During a release-candidate cycle, bugfixes go on the `x.*` branch and are
+  merged back into `master` before the final release.
+
+Do **not** add new features to a maintenance branch.
+
+---
+
+## 4. Versioning scheme
+
+Versions follow the format **`MAJOR.MINOR.PATCH`** where the `MINOR` number
+conveys the development stage of the next major release:
+
+| Minor range | Stage | Rules |
+|---|---|---|
+| `x.90.y` | **Alpha** toward `x+1` | Stays on `master`. Development is open: new features are welcome, regressions are acceptable. |
+| `x.95.y` | **Beta** toward `x+1` | The `x+1.*` maintenance branch is created at this point. No regression unless absolutely necessary; new features still allowed. |
+| `x.99.y` | **RC** toward `x+1` | Bugfixes only. No new features. No regression allowed. Becomes `x+1.0.0` when stable. |
+
+Examples: `3.90.1` is the first alpha toward `4.0`, `3.99.2` is the second
+release candidate for `4.0`.
+
+The `PATCH` number increments freely within a stage. A bump in `MINOR`
+(e.g. `90` → `95`) always indicates a stage promotion in development phase.
+
+Any experimental version must have it's dedicated branch.
