+* Patched package-manager to kpmx to publish on pypi
+
+
+## [1.7.0] - 2025-12-14
+
+* * New *pkgmgr publish* command to publish repository artifacts to PyPI based on the *MIRRORS* file.
+* Automatically selects the current repository when no explicit selection is given.
+* Publishes only when a semantic version tag is present on *HEAD*; otherwise skips with a clear info message.
+* Supports non-interactive mode for CI environments via *--non-interactive*.
+
+
+## [1.6.4] - 2025-12-14
+
+* * Improved reliability of Nix installs and updates, including automatic resolution of profile conflicts and better handling of GitHub 403 rate limits.
+* More stable launcher behavior in packaged and virtual-env setups.
+* Enhanced mirror and remote handling: repository owner/name are derived from URLs, with smoother provisioning and clearer credential handling.
+* More reliable releases and artifacts due to safer CI behavior when no version tag is present.
+
+
+## [1.6.3] - 2025-12-14
+
+* ***Fixed:*** Corrected repository path resolution so release and version logic consistently use the canonical packaging/* layout, preventing changelog and packaging files from being read or updated from incorrect locations.
+
+
+## [1.6.2] - 2025-12-14
+
+* **pkgmgr version** now also shows the installed pkgmgr version when run outside a repository.
+
+
+## [1.6.1] - 2025-12-14
+
+* * Added automatic retry handling for GitHub 403 / rate-limit errors during Nix flake installs (Fibonacci backoff with jitter).
+
+
+## [1.6.0] - 2025-12-14
+
+* *** Changed ***
+- Unified update handling via a single top-level `pkgmgr update` command, removing ambiguous update paths.
+- Improved update reliability by routing all update logic through a central UpdateManager.
+- Renamed system update flag from `--system-update` to `--system` for clarity and consistency.
+- Made mirror handling explicit and safer by separating setup, check, and provision responsibilities.
+- Improved credential resolution for remote providers (environment → keyring → interactive).
+
+*** Added ***
+- Optional system updates via `pkgmgr update --system` (Arch, Debian/Ubuntu, Fedora/RHEL).
+- `pkgmgr install --update` to force re-running installers and refresh existing installations.
+- Remote repository provisioning for mirrors on supported providers.
+- Extended end-to-end test coverage for update and mirror workflows.
+
+*** Fixed ***
+- Resolved “Unknown repos command: update” errors after CLI refactoring.
+- Improved Nix update stability and reduced CI failures caused by transient rate limits.
+
+
+## [1.5.0] - 2025-12-13
+
+* - Commands now show live output while running, making long operations easier to follow
+- Error messages include full command output, making failures easier to understand and debug
+- Deinstallation is more complete and predictable, removing CLI links and properly cleaning up repositories
+- Preview mode is more trustworthy, clearly showing what would happen without making changes
+- Repository configuration problems are detected earlier with clear, user-friendly explanations
+- More consistent behavior across different Linux distributions
+- More reliable execution in Docker containers and CI environments
+- Nix-based execution works more smoothly, especially when running as root or inside containers
+- Existing commands, scripts, and workflows continue to work without any breaking changes

By exporting these values, every Make target (e.g., build, build-no-cache, build-missing, test-container, test-unit, test-e2e) and every delegated script in scripts/build/ and scripts/test/ now receives a consistent view of the supported distributions and their base container images.

 ## Features 🚀
 
-### Multi-distro development & packaging
+PKGMGR enables multi-distro development and packaging by managing multiple
+repositories from a single configuration file. It drives complete release
+pipelines across Linux distributions using Nix flakes, Python build metadata,
+native OS packages such as Arch, Debian and RPM formats, and additional ecosystem
+integrations like Ansible.
 
-* Manage **many repositories at once** from a single `config/config.yaml`.
-* Drive full **release pipelines** across Linux distributions using:
+All functionality is exposed through a unified `pkgmgr` command-line interface
+that works identically on every supported distribution. It combines repository
+management, Git operations, Docker and Compose orchestration, as well as
+versioning, release and changelog workflows. Many commands support a preview
+mode, allowing you to inspect the underlying actions before they are executed.
 
-  * Nix flakes (`flake.nix`)
-  * PyPI style builds (`pyproject.toml`)
-  * OS packages (PKGBUILD, Debian control/changelog, RPM spec)
-  * Ansible Galaxy metadata and more.
-
-### Rich CLI for daily work
-
-All commands are exposed via the `pkgmgr` CLI and are available on every distro:
-
-* **Repository management**
-
-  * `clone`, `update`, `install`, `delete`, `deinstall`, `path`, `list`, `config`
-* **Git proxies**
-
-  * `pull`, `push`, `status`, `diff`, `add`, `show`, `checkout`,
-    `reset`, `revert`, `rebase`, `commit`, `branch`
-* **Docker & Compose orchestration**
-
-  * `build`, `up`, `down`, `exec`, `ps`, `start`, `stop`, `restart`
-* **Release toolchain**
-
-  * `version`, `release`, `changelog`, `make`
-* **Mirror & workflow helpers**
-
-  * `mirror` (list/diff/merge/setup), `shell`, `terminal`, `code`, `explore`
-
-Many of these commands support `--preview` mode so you can inspect the
-underlying Git or Docker calls without executing them.

 ## Installation ⚙️
 
 PKGMGR can be installed using `make`.
 The setup mode defines **which runtime layers are prepared**.
-
 ---
 
+### Download
+
+```bash
+git clone https://github.com/kevinveenbirkenbach/package-manager.git
+cd package-manager
+```
+
+### Dependency installation (optional)
+
+System dependencies required **before running any *make* commands** are installed via:
+
+```
+scripts/installation/dependencies.sh
+```
+
+The script detects and normalizes the OS and installs the required **system-level dependencies** accordingly.
+
+### Install
+
+```bash
+git clone https://github.com/kevinveenbirkenbach/package-manager.git
+cd package-manager
+make install
+```

-## Run without installation (Nix)
+Alles klar 🙂
+Hier ist der **RUN-Abschnitt ohne Gedankenstriche**, klar nach **Nix, Docker und venv** getrennt:
 
-Run PKGMGR directly via Nix Flakes.
+---
+
+## Run PKGMGR 🧰
+
+PKGMGR can be executed in different environments.
+All modes expose the same CLI and commands.
+
+---
+
+### Run via Nix (no installation)
 
 ```bash
 nix run github:kevinveenbirkenbach/package-manager#pkgmgr -- --help
 ```
 
-Example:
+---
 
-```bash
-nix run github:kevinveenbirkenbach/package-manager#pkgmgr -- version pkgmgr
-```
+### Run via Docker 🐳
 
-Notes:
+PKGMGR can be executed **inside Docker containers** for CI, testing and isolated
+workflows.
+---
 
-* full flake URL required
-* `--` separates Nix and PKGMGR arguments
-* can be used alongside any setup mode
+#### Container types
+
+Two container types are available.
+
+
+| Image type | Contains                      | Typical use             |
+| ---------- | ----------------------------- | ----------------------- |
+| **Virgin** | Base OS + system dependencies | Clean test environments |
+| **Stable** | PKGMGR + Nix (flakes enabled) | Ready-to-use workflows  |
+
+Example images:
+
+* Virgin: `pkgmgr-arch-virgin`
+* Stable: `ghcr.io/kevinveenbirkenbach/pkgmgr:stable`
+
+
+Use **virgin images** for isolated test runs,
+use the **stable image** for fast, reproducible execution.
 
 ---
 
-## Usage 🧰
+#### Run examples
 
-After installation, the main entry point is:
+```bash
+docker run --rm -it \
+  -v "$PWD":/src \
+  -w /src \
+  ghcr.io/kevinveenbirkenbach/pkgmgr:stable \
+  pkgmgr --help
+```
+
+---
+
+### Run via virtual environment (venv)
+
+After activating the venv:
 
 ```bash
 pkgmgr --help
 ```
 
-This prints a list of all available subcommands.
-The help for each command is available via:
+---
+
+This allows you to choose between zero install execution using Nix, fully prebuilt
+Docker environments or local isolated venv setups with identical command behavior.

-Installer for Nix flakes.
-
-If a repository contains flake.nix and the 'nix' command is available, this
-installer will try to install profile outputs from the flake.
-
-Behavior:
-  - If flake.nix is present and `nix` exists on PATH:
-      * First remove any existing `package-manager` profile entry (best-effort).
-      * Then install one or more flake outputs via `nix profile install`.
-  - For the package-manager repo:
-      * `pkgmgr` is mandatory (CLI), `default` is optional.
-  - For all other repos:
-      * `default` is mandatory.
-
-Special handling:
-  - If PKGMGR_DISABLE_NIX_FLAKE_INSTALLER=1 is set, the installer is
-    globally disabled (useful for CI or debugging).
-
-The higher-level InstallationPipeline and CLI-layer model decide when this
-installer is allowed to run, based on where the current CLI comes from
-(e.g. Nix, OS packages, Python, Makefile).

-PythonInstaller — install Python projects defined via pyproject.toml.
-
-Installation rules:
-
-1. pip command resolution:
-      a) If PKGMGR_PIP is set → use it exactly as provided.
-      b) Else if running inside a virtualenv → use `sys.executable -m pip`.
-      c) Else → create/use a per-repository virtualenv under ~/.venvs/<repo>/.
-
-2. Installation target:
-      - Always install into the resolved pip environment.
-      - Never modify system Python, never rely on --user.
-      - Nix-immutable systems (PEP 668) are automatically avoided because we
-        never touch system Python.
-
-3. The installer is skipped when:
-      - PKGMGR_DISABLE_PYTHON_INSTALLER=1 is set.
-      - The repository has no pyproject.toml.
-
-All pip failures are treated as fatal.
