+## [1.8.0] - 2025-12-15
+
+* *** New Features: ***
+- **Silent Updates**: You can now use the `--silent` flag during installs and updates to suppress error messages for individual repositories and get a single summary at the end. This ensures the process continues even if some repositories fail, while still preserving interactive checks when not in silent mode.
+- **Repository Scaffolding**: The process for creating new repositories has been improved. You can now use templates to scaffold repositories with a preview and automatic mirror setup.
+
+*** Bug Fixes: ***
+- **Pip Installation**: Pip is now installed automatically on all supported systems. This includes `python-pip` for Arch and `python3-pip` for CentOS, Debian, Fedora, and Ubuntu, ensuring that pip is available for Python package installations.
+- **Pacman Keyring**: Fixed an issue on Arch Linux where package installation would fail due to missing keys. The pacman keyring is now properly initialized before installing packages.
+
+
+## [1.7.2] - 2025-12-15
+
+* * Git mirrors are now resolved consistently (origin → MIRRORS file → config → default).
+* The `origin` remote is always enforced to use the primary URL for both fetch and push.
+* Additional mirrors are added as extra push targets without duplication.
+* Local and remote mirror setup behaves more predictably and consistently.
+* Improved test coverage ensures stable origin and push URL handling.
+
+
+## [1.7.1] - 2025-12-14
+
+* 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.
