+This post gives an overview of the recent updates to the _Writing an OS in Rust_ blog and the used libraries and tools.
+
+I finished my master thesis and got my degree this month, so I only had limited time for my open source work. I still managed to perform a few minor updates, including code simplications for the _Paging Implementation_ post and the evaluation of GitHub Actions as a CI service.
+
+## `blog_os`
+
+- [Improve Paging Implementation Post](https://github.com/phil-opp/blog_os/pull/666): Improves and simplifies the code in multiple places
+- [Use GitHub Actions to build and deploy blog](https://github.com/phil-opp/blog_os/pull/660)
