Release version 1.3.0

* Ensure nix is reachable for sudo on CentOS by providing /usr/bin and /usr/sbin fallbacks when absent
* Keep /usr/local/bin as primary CI path without breaking non-login shells
* Never overwrite distro-managed nix binaries (Arch-safe)
* Stabilize e2e and virgin-user tests across all distros

+## [1.3.0] - 2025-12-12
+
+* **Minor release – Stability & CI hardening**
+
+* Stabilized Nix resolution and global symlink handling across Arch, CentOS, Debian, and Ubuntu
+* Ensured Nix works reliably in CI, sudo, login, and non-login shells without overriding distro-managed paths
+* Improved error handling and deterministic behavior for non-root environments
+* Refactored Docker and CI workflows for reproducible multi-distro virgin tests
+* Made E2E tests more realistic by executing real CLI commands
+* Fixed Python compatibility and missing dependencies on affected distros
+
+
+## [1.2.1] - 2025-12-12
+
+* **Changed**
+
+* Split container tests into *virtualenv* and *Nix flake* environments to clearly separate Python and Nix responsibilities.
+
+**Fixed**
+
+* Fixed Nix installer permission issues when running under a different user in containers.
+* Improved reliability of post-install Nix initialization across all distro packages.
+
+**CI**
+
+* Replaced generic container tests with explicit environment checks.
+* Validate Nix availability via *nix flake* tests instead of Docker build-time side effects.
+
+
+## [1.2.0] - 2025-12-12
+
+* **Release workflow overhaul**
+
+* Introduced a fully structured release workflow with clear phases and safeguards
+* Added preview-first releases with explicit confirmation before execution
+* Automatic handling of *latest* tag when a release is the newest version
+* Optional branch closing after successful releases with interactive confirmation
+* Improved safety by syncing with remote before any changes
+* Clear separation of concerns (workflow, git handling, prompts, versioning)
+
+
+## [1.1.0] - 2025-12-12
+
+* Added *branch drop* for destructive branch deletion and introduced *--force/-f* flags for branch close and branch drop to skip confirmation prompts.
+
+
+## [1.0.0] - 2025-12-11
+
+* **1.0.0 – Official Stable Release 🎉**
+*First stable release of PKGMGR, the multi-distro development and package workflow manager.*
+
+---
+
+**Key Features**
+
+**Core Functionality**
+
+* Manage many repositories with one CLI: `clone`, `update`, `install`, `list`, `path`, `config`
+* Proxy wrappers for Git, Docker/Compose and Make
+* Multi-repo execution with safe *preview mode*
+* Mirror management: `mirror list/diff/merge/setup`
+
+**Releases & Versioning**
+
+* Automated SemVer bumps, tagging and changelog generation
+* Supports PKGBUILD, Debian, RPM, pyproject.toml, flake.nix
+
+**Developer Tools**
+
+* Open repositories in VS Code, file manager or terminal
+* Unified workflows across all major Linux distros
+
+**Nix Integration**
+
+* Cross-distro reproducible builds via Nix flakes
+* CI-tested across all supported environments
+
+---
+
+**Summary**
+PKGMGR 1.0.0 unifies repository management, build tooling, release automation and reproducible multi-distro workflows into one cohesive CLI tool.
+
+*This is the first official stable release.*
+
+
 ## [0.10.2] - 2025-12-11
 
 * * Stable tag now updates only when a new highest version is released.

+operating systems** (Arch, Debian, Ubuntu, Fedora, CentOS, …).
+
+PKGMGR is implemented in **Python** and uses **Nix (flakes)** as a foundation for
+distribution-independent builds and tooling. On top of that it provides a rich
+CLI that proxies common developer tools (Git, Docker, Make, …) and glues them
+together into repeatable development workflows.
+
+---
+
+## Why PKGMGR? 🧠
+
+Traditional distro package managers like `apt`, `pacman` or `dnf` focus on a
+single operating system. PKGMGR instead focuses on **your repositories and
+development lifecycle**:
+
+* one configuration for all your repos,
+* one CLI to interact with them,
+* one Nix-based layer to keep tooling reproducible across distros.
+
+You keep using your native package manager where it makes sense – PKGMGR
+coordinates the *development and release flow* around it.
+
+---
 
 ## Features 🚀
 
-- **Installation & Setup:**  
+### Multi-distro development & packaging
-  Create executable wrappers with auto-detected commands (e.g. `main.sh` or `main.py`).
+
-  
+* Manage **many repositories at once** from a single `config/config.yaml`.
-- **Git Operations:**  
+* Drive full **release pipelines** across Linux distributions using:
-  Easily perform `git pull`, `push`, `status`, `commit`, `diff`, `add`, `show`, and `checkout` with extra parameters passed through.
+
-  
+  * Nix flakes (`flake.nix`)
-- **Configuration Management:**  
+  * PyPI style builds (`pyproject.toml`)
-  Manage repository configurations via a default file (`config/defaults.yaml`) and a user-specific file (`config/config.yaml`). Initialize, add, delete, or ignore entries using subcommands.
+  * OS packages (PKGBUILD, Debian control/changelog, RPM spec)
-  
+  * Ansible Galaxy metadata and more.
-- **Path & Listing:**  
+
-  Display repository paths or list all configured packages with their details.
+### Rich CLI for daily work
-  
+
-- **Custom Aliases:**  
+All commands are exposed via the `pkgmgr` CLI and are available on every distro:
-  Generate and manage custom aliases for easy command invocation.
+
+* **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.
+
+### Full development workflows
+
+PKGMGR is not just a helper around Git commands. Combined with its release and
+versioning features it can drive **end-to-end workflows**:
+
+1. Clone and mirror repositories.
+2. Run tests and builds through `make` or Nix.
+3. Bump versions, update changelogs and tags.
+4. Build distro-specific packages.
+5. Keep all mirrors and working copies in sync.
+
+The extensive E2E tests (`tests/e2e/`) and GitHub Actions workflows (including
+“virgin user” and “virgin root” Arch tests) validate these flows across
+different Linux environments.

 ## Installation ⚙️
 
-Clone the repository and ensure your `~/.local/bin` is in your system PATH:
+### 1. Get the latest stable version
+
+For a stable setup, use the **latest tagged release** (the tag pointed to by
+`latest`):
 
 ```bash
 git clone https://github.com/kevinveenbirkenbach/package-manager.git
 cd package-manager
+
+# Optional but recommended: checkout the latest stable tag
+git fetch --tags
+git checkout "$(git describe --tags --abbrev=0)"
 ```
 
-Install make and pip if not installed yet:
+### 2. Install via Make
+
+The project ships with a Makefile that encapsulates the typical installation
+flow. On most systems you only need:
 
 ```bash
-pacman -S make python-pip
+# Ensure make, Python and pip are installed via your distro package manager
+# (e.g. pacman -S make python python-pip, apt install make python3-pip, ...)
+
+make install
 ```
 
-Then, run the following command to set up the project:
+This will:
+
+* create or reuse a Python virtual environment,
+* install PKGMGR (and its Python dependencies) into that environment,
+* expose the `pkgmgr` executable on your PATH (usually via `~/.local/bin`),
+* prepare Nix-based integration where available so PKGMGR can build and manage
+  packages distribution-independently.
+
+For development use, you can also run:
 
 ```bash
 make setup
 ```
 
-The `make setup` command will:
+which prepares the environment and leaves you with a fully wired development
-- Make `main.py` executable.
+workspace (including Nix, tests and scripts).
-- Install required packages from `requirements.txt`.
+
-- Execute `python main.py install` to complete the installation.
+---
+
+## Usage 🧰
+
+After installation, the main entry point is:
+
+```bash
+pkgmgr --help
+```
+
+This prints a list of all available subcommands, for example:
+
+* `pkgmgr list --all` – show all repositories in the config
+* `pkgmgr update --all --clone-mode https` – update every repository
+* `pkgmgr release patch --preview` – simulate a patch release
+* `pkgmgr version --all` – show version information for all repositories
+* `pkgmgr mirror setup --preview --all` – prepare Git mirrors (no changes in preview)
+* `pkgmgr make install --preview pkgmgr` – preview make install for the pkgmgr repo
+
+The help for each command is available via:
+
+```bash
+pkgmgr <command> --help
+```

+# Release Action
+
+This module implements the `pkgmgr release` workflow.
+
+It provides a controlled, reproducible release process that:
+- bumps the project version
+- updates all supported packaging formats
+- creates and pushes Git tags
+- optionally maintains a floating `latest` tag
+- optionally closes the current branch
+
+The implementation is intentionally explicit and conservative to avoid
+accidental releases or broken Git states.
+
+---
+
+## What the Release Command Does
+
+A release performs the following high-level steps:
+
+1. Synchronize the current branch with its upstream (fast-forward only)
+2. Determine the next semantic version
+3. Update all versioned files
+4. Commit the release
+5. Create and push a version tag
+6. Optionally update and push the floating `latest` tag
+7. Optionally close the current branch
+
+All steps support **preview (dry-run)** mode.
+
+---
+
+## Supported Files Updated During a Release
+
+If present, the following files are updated automatically:
+
+- `pyproject.toml`
+- `CHANGELOG.md`
+- `flake.nix`
+- `PKGBUILD`
+- `package-manager.spec`
+- `debian/changelog`
+
+Missing files are skipped gracefully.
+
+---
+
+## Git Safety Rules
+
+The release workflow enforces strict Git safety guarantees:
+
+- A `git pull --ff-only` is executed **before any file modifications**
+- No merge commits are ever created automatically
+- Only the current branch and the newly created version tag are pushed
+- `git push --tags` is intentionally **not** used
+- The floating `latest` tag is force-pushed only when required
+
+---
+
+## Semantic Versioning
+
+The next version is calculated from existing Git tags:
+
+- Tags must follow the format `vX.Y.Z`
+- The release type controls the version bump:
+  - `patch`
+  - `minor`
+  - `major`
+
+The new tag is always created as an **annotated tag**.
+
+---
+
+## Floating `latest` Tag
+
+The floating `latest` tag is handled explicitly:
+
+- `latest` is updated **only if** the new version is the highest existing version
+- Version comparison uses natural version sorting (`sort -V`)
+- `latest` always points to the commit behind the version tag
+- Updating `latest` uses a forced push by design
+
+This guarantees that `latest` always represents the highest released version,
+never an older release.
+
+---
+
+## Preview Mode
+
+Preview mode (`--preview`) performs a full dry-run:
+
+- No files are modified
+- No Git commands are executed
+- All intended actions are printed
+
+Example preview output includes:
+- version bump
+- file updates
+- commit message
+- tag creation
+- branch and tag pushes
+- `latest` update (if applicable)
+
+---
+
+## Interactive vs Forced Mode
+
+### Interactive (default)
+
+1. Run a preview
+2. Ask for confirmation
+3. Execute the real release
+
+### Forced (`--force`)
+
+- Skips preview and confirmation
+- Skips branch deletion prompts
+- Executes the release immediately
+
+---
+
+## Branch Closing (`--close`)
+
+When `--close` is enabled:
+
+- `main` and `master` are **never** deleted
+- Other branches:
+  - prompt for confirmation (`y/N`)
+  - can be skipped using `--force`
+- Branch deletion happens **only after** a successful release
+
+---
+

+
+## Design Goals
+
+- Deterministic and reproducible releases
+- No implicit Git side effects
+- Explicit tag handling
+- Safe defaults for interactive usage
+- Automation-friendly forced mode
+- Clear separation of concerns:
+  - `workflow.py` – orchestration
+  - `git_ops.py` – Git operations
+  - `prompts.py` – user interaction
+  - `versioning.py` – SemVer logic
+
+---
+
+## Summary
+
+`pkgmgr release` is a **deliberately strict** release mechanism.
+
+It trades convenience for safety, traceability, and correctness — making it
+suitable for both interactive development workflows and fully automated CI/CD

-Release helper for pkgmgr (public entry point).
-
-This package provides the high-level `release()` function used by the
-pkgmgr CLI to perform versioned releases:
-
-  - Determine the next semantic version based on existing Git tags.
-  - Update pyproject.toml with the new version.
-  - Update additional packaging files (flake.nix, PKGBUILD,
-    debian/changelog, RPM spec) where present.
-  - Prepend a basic entry to CHANGELOG.md.
-  - Move the floating 'latest' tag to the newly created release tag so
-    the newest release is always marked as latest.
-
-Additional behaviour:
-  - If `preview=True` (from --preview), no files are written and no
-    Git commands are executed. Instead, a detailed summary of the
-    planned changes and commands is printed.
-  - If `preview=False` and not forced, the release is executed in two
-    phases:
-      1) Preview-only run (dry-run).
-      2) Interactive confirmation, then real release if confirmed.
-    This confirmation can be skipped with the `force=True` flag.
-  - Before creating and pushing tags, main/master is updated from origin
-    when the release is performed on one of these branches.
-  - If `close=True` is used and the current branch is not main/master,
-    the branch will be closed via branch_commands.close_branch() after
-    a successful release.

-A powerful toolchain that unifies and automates workflows across heterogeneous
+repositories and packaging formats (pyproject.toml, flake.nix,
-project ecosystems. pkgmgr is not only a package manager — it is a full 
+PKGBUILD, debian, Ansible, …) with one CLI.
