-### 2.1. Initial configuration
+### 2.1. Interactive vs non-interactive shells
+
+`profile.sh` detects whether the current shell is interactive.
+
+In interactive shells (typical terminal sessions), profile enables
+interactive-only features such as:
+- aliases from `[aliases]`
+- bash completion scripts from `profile.d/bash-completion/`
+- prompt initialization (`PROMPT_COMMAND` and timer hook)
+- welcome display (`showinfo`) and startup update check (`check_updates -q`)
+
+In non-interactive shells (typical script execution), those features are
+intentionally skipped to avoid side effects and startup noise. Public functions
+remain available after sourcing, so scripts can still call profile helpers.

+## [4.1.0] — 2026-05-07
+
+### Added
+- `profile.sh --install` command to automatically configure profile loading in
+  shell startup files.
+- `--install --bashrc` and `--install --profile` target selectors for
+  single-file installation.
+- **`git.sh`** — entirely new module providing git workflow helpers: `gst`,
+  `ggraph`, `gsync`, `gacp`, `greset`, `gwip`, `gprune`, `groot`.
+- Dedicated git helper completions under `profile.d/bash-completion/`, loaded
+  automatically in interactive sessions from `profile.d/bash-completion/*.sh`.
+
+### Changed
+- `disp` now wraps long messages on terminal width, avoids mid-word splits, and
+  aligns continuation lines with the message body after the prefix.
+- `help` now supports `help <command>` and delegates to `<command> --help`.
+- `taz` now supports `-p auto` / `--parallel=auto` to automatically use the
+  runtime CPU count. This mode is now the default via
+  `TAZ_DEFAULT_THREADS=auto`.
+- `taz` keeps backward compatibility with legacy `TAZ_DEFAULT_THREADS=0`
+  values by interpreting `0` as `auto`.
+
+### Fixed
+- Startup responsiveness improved: `check_updates -q` now uses a short network
+  timeout so unavailable/slow networks no longer delay prompt readiness.
+- `dwl` gained timeout support (`-t` / `--timeout`) and is now used by quiet
+  startup update checks to enforce fast failure.
+- `profile.sh` now detects direct execution and warns that it is designed to be
+  sourced.
+
+## [4.0.0] — 2026-04-23
+
+### Added
+- New `profile.conf` reference template at `doc/profile.conf.example`.
+- Dynamic locale shortcuts generated from `SET_LOCALE` and startup default
+  language selection through `DEFAULT_LANG`.
+- Prompt theming system with bundled themes (`default`, `dark`, `light`,
+  `solarized`, `solarized-light`, `monokai`, `monochrome`, `abyss`, `plasma`,
+  `adwaita`) and per-key prompt color overrides.
+- Module defaults exposed as configuration keys in `profile.conf`.
+
+### Changed
+- `utaz` now supports a wider range of archive formats.
+- Prompt and theme rendering improved, including better 24-bit color support.
+- Overall code quality and maintainability improved across modules.
+
+### Documentation
+- README updated with full function reference and configuration tables.
+- New and expanded docs in `doc/` (`CONTRIBUTING.md`, `FAQ.md`, `todo.md`).
+- Historical releases imported from `history.txt` into this changelog.
+
+---
+
+## [3.99.2-4_rc_2] — 2026-04-21
+
+### 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`.

+|---|---|---|
+| `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.

 ## Installation & loading
 
+**Q: How do I install profile automatically into my shell startup files?**
+
+Run the installer directly (no need to source first):
+```bash
+bash <installpath>/profile/profile.sh --install
+```
+This appends the required `source` line to both `~/.bashrc` and `~/.profile`.
+To target only one file:
+```bash
+bash <installpath>/profile/profile.sh --install --bashrc
+bash <installpath>/profile/profile.sh --install --profile
+```
+The operation is idempotent — running it again will not add a duplicate line.
+
+---
+
+**Q: I ran `profile.sh` directly and got a warning about sourcing.**
+
+profile.sh is designed to be *sourced*, not executed:
+```bash
+source <installpath>/profile/profile.sh
+```
+The only exception is `--install`, which must be passed to a direct execution
+(`bash profile.sh --install`) to set up the sourcing line automatically.

+**Q: Can I use profile functions in scripts?**
+
+Yes. The supported way is to source `profile.sh` from a Bash script:
+```bash
+#!/usr/bin/env bash
+source /path/to/profile/profile.sh
+
+taz -p auto -f lz mydir
+```
+You can also source one module directly (for example
+`profile.d/compress.sh`) if you only need a subset of functions.
+
+When you source a module directly, profile configuration parsing/loading from
+`profile.sh` is skipped, so defaults from `profile.conf` are not applied unless
+your script loads them explicitly.
+
+`profile.sh` also detects whether the current shell is interactive. In
+non-interactive shells (typical script execution), interactive-only features
+are intentionally disabled: prompt setup, aliases, welcome/info messages, and
+startup update checks are not enabled.
+
+In all cases, avoid aliases in scripts. Use real commands/functions instead,
+because alias expansion is interactive-shell oriented and can be disabled or
+behave differently in non-interactive execution.

+## Git helpers
+
+**Q: What git helper functions does profile provide?**
+
+All git helpers are defined in `profile.d/git.sh` (new in 4.1.0):
+
+| Command | Purpose |
+|---|---|
+| `gst` | Compact status with branch tracking info |
+| `ggraph` | Decorated history graph |
+| `gsync` | Fetch and rebase onto upstream |
+| `gacp` | Add, commit and push in one command |
+| `greset` | Reset to upstream, stashing local changes first |
+| `gwip` | Quick WIP checkpoint commit |
+| `gprune` | Delete merged local branches |
+| `groot` | Print or cd to repository root |
+
+All commands accept `-h` / `--help`.
+
+---
+
+**Q: Tab completion for `gacp` does not show modified files.**
+
+Profile ships dedicated completions in `profile.d/bash-completion/git-completion.sh`,
+loaded automatically in interactive sessions. If completions are missing,
+check that the system git completion is installed:
+```bash
+# Debian / Ubuntu
+apt-get install bash-completion
+# Fedora / RHEL
+dnf install bash-completion
+```
+When the native git completion helpers are available, `gacp` path completion
+behaves exactly like `git add` (modified files, untracked files, directories).
+
+---
+
+**Q: `gacp` says "No files specified" even though I passed `-a`.**
+
+The `-a` / `--auto` flag adds all modified files (equivalent to `git add -A`).
+The default depends on `GIT_GACP_AUTO_ADD` in `profile.conf`:
+```ini
+[git]
+GIT_GACP_AUTO_ADD = 1
+```
+Set to `1` to make `-a` the default.

 ---
 
+**Q: How do I limit how long `dwl` waits for a download?**
+
+Use the `-t` / `--timeout` option:
+```bash
+dwl -t 5 https://example.com/file.txt /tmp/file.txt
+```
+This sets a 5-second cap on both the connection and the overall transfer.
+The timeout is propagated to `curl` (`--max-time` + `--connect-timeout`),
+`wget` (`--timeout`), or `fetch` (`-T`) transparently.
+
+---
+
+**Q: The prompt takes a long time to appear when my network is unavailable.**
+
+Fixed in 4.1.0. `check_updates -q` (called at startup) now enforces a
+3-second network timeout. If the update server is unreachable the check
+fails silently and the prompt appears immediately.
+
+---
+
+**Q: `help` only shows a list of functions. Can I get usage for a specific one?**
+
+Yes — pass the command name as an argument:
+```bash
+help gacp
+help dwl
+help taz
+```
+This calls `<command> --help` and prints the full usage for that function.
+
+---
+
 **Q: `pkgs` does not find packages I know are installed.**
 
-`pkgs` delegates to `dpkg -l` (Debian/Ubuntu) or `rpm -qa` (RHEL/Fedora).
-If your distribution uses a different package manager (pacman, apk, brew …)
-it is not yet supported. See `doc/todo.md` for the tracking issue.
+`pkgs` uses `get_pkgmgr` to detect the active package manager and delegates
+to the appropriate tool. Supported families: `apt` (Debian/Ubuntu),
+`dnf` / `yum` (RHEL/Fedora), `zypper` (openSUSE), `pacman` (Arch),
+`apk` (Alpine), `portage` (Gentoo), `xbps` (Void), `nix`, `brew` (macOS).
+If your distribution is not detected, run `get_pkgmgr` to see what is
+identified, and check that the package manager binary is in your `PATH`.
