 ## Release Notes
 
+### [1.0.0-alpha.6](https://github.com/runemalm/py-dependency-injection/releases/tag/v1.0.0-alpha.6) (2024-03-23)
+
+- **Factory Registration:** Added support for registering dependencies using factory functions for dynamic instantiation.
+- **Instance Registration:** Enabled registering existing instances as dependencies.
+- **Tag-based Registration and Resolution:** Introduced the ability to register and resolve dependencies using tags for flexible dependency management.
+
 ### [1.0.0-alpha.5](https://github.com/runemalm/py-dependency-injection/releases/tag/v1.0.0-alpha.5) (2024-03-03)
 
 - **Critical Package Integrity Fix**: This release addresses a critical issue that affected the packaging of the Python library in all previous alpha releases (1.0.0-alpha.1 to 1.0.0-alpha.4). The problem involved missing source files in the distribution, rendering the library incomplete and non-functional.
