+See [the merged pull request list](https://github.com/phil-opp/blog_os/pulls?q=is%3Apr+is%3Aclosed+merged%3A2020-10-01..2020-11-01) for the complete set of changes this month. Thanks a lot to all contributors!

+In case you speak Persian: There is currently an open pull request to [add a Persian translation of `Bare Bones` chapter](https://github.com/phil-opp/blog_os/pull/878) that needs reviews. Thanks to everyone involved!

+In [in our previous status update](@/this-month/2020-09/index.md#phil-opp-blog-os) I described my plans to rewrite the blog on top of the upcoming UEFI bootloader. In the past month I started rewriting the _Minimal Rust Kernel_ post for this. Unfortunately, I'm still facing build-related issues because of [limitations of Cargo's config files](https://github.com/rust-lang/cargo/pull/8757#issuecomment-713897532). To resolve these (and other) `.cargo/config` issues, I created a proposal on the Rust internals forum to [make some `.cargo/config` options available in `Cargo.toml` too](https://internals.rust-lang.org/t/proposal-move-some-cargo-config-settings-to-cargo-toml/13336). Feel free to join the discussion if it's relevant to you!
