+## Project Updates
+
+In this section, we give an overview of notable changes to the projects hosted under the [`rust-osdev`] organization.
+
+[`rust-osdev`]: https://github.com/rust-osdev/about
+
+### [`x86_64`](https://github.com/rust-osdev/x86_64)
+
+The `x86_64` crate provides various abstractions for `x86_64` systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.
+
+In September, we merged the following changes:
+
+- [Add `clean_up` and `clean_up_with_filter`](https://github.com/rust-osdev/x86_64/pull/264) for deallocating unused page tables
+- [Add exception vector type](https://github.com/rust-osdev/x86_64/pull/303)
+- [Bump `bit_field` to 0.10.1](https://github.com/rust-osdev/x86_64/pull/306)
+- [Release version 0.14.5](https://github.com/rust-osdev/x86_64/pull/304)
+- [Move segment types into a new registers::segmentation module](https://github.com/rust-osdev/x86_64/pull/309)
+- [Release version 0.14.6](https://github.com/rust-osdev/x86_64/pull/310)
+
+Thanks to [@Freax13](https://github.com/Freax13), [@npmccallum](https://github.com/npmccallum), and [@mkroening](https://github.com/mkroening) for their contributions!
+
+
+### [`uefi-rs`](https://github.com/rust-osdev/uefi-rs)
+
+The `uefi` crate provides safe and performant wrappers for [UEFI](https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface), the successor to the BIOS.
+
+This month, we merged the following changes:
+
+- [Improve macro errors](https://github.com/rust-osdev/uefi-rs/pull/277)
+- [Implement missing methods of `DebugSupport`](https://github.com/rust-osdev/uefi-rs/pull/290)
+- [macros: add compilation tests](https://github.com/rust-osdev/uefi-rs/pull/286)
+- [Remove attribute to enable `const_panic`](https://github.com/rust-osdev/uefi-rs/pull/296)
+- [Add a test command to build.py and also use it in the CI](https://github.com/rust-osdev/uefi-rs/pull/283)
+
+Thanks to [@necauqua](https://github.com/necauqua) and [@timrobertsdev](https://github.com/timrobertsdev) for their contributions!
+
+### [`bootloader`](https://github.com/rust-osdev/bootloader)
+
+The `bootloader` crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables.
+
+We finally merged a long-desired feature this month:
+
+- [Framebuffer configuration](https://github.com/rust-osdev/bootloader/pull/179) <span class="gray">(published as `v0.10.9`)</span>
+
+Thanks to [@anellie](https://github.com/anellie) for this contribution!
+
+### [`multboot2`](https://github.com/rust-osdev/multiboot2)
+
+The `multiboot2` crate provides abstraction types for the boot information of multiboot2 bootloaders.
+
+It is now part of a workspace and lives next to the new crate `multiboot2-header`.
+
+The following changes were merged this month:
+
+- [Code style improvements + optional CI job (clippy, rustfmt, rustdoc)](https://github.com/rust-osdev/multiboot2/pull/92)
+- [std in tests; hash for TagType](https://github.com/rust-osdev/multiboot2/pull/94) 
+- [editorconfig file](https://github.com/rust-osdev/multiboot2/pull/93)
+- [prepared cargo workspace, as discussed in PR #79](https://github.com/rust-osdev/multiboot2/pull/86)
+
+The changes were published as <span class="gray">`v0.12.2`</span>.
+
+
+### [`multboot2-header`](https://github.com/rust-osdev/multiboot2) (**new**)
+
+The `multiboot2-header` crate provides abstraction types for the Multiboot2 header 
+and a builder struct to construct these headers. The corresponding repository was 
+prepared ([#86](https://github.com/rust-osdev/multiboot2/pull/86)) and the initial release 
+is expected in early October. See [#95](https://github.com/rust-osdev/multiboot2/pull/95) for more details.
