+## 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
+
+### [`uefi-rs`](https://github.com/rust-osdev/uefi-rs)
+
+<span class="maintainers">Maintained by [@GabrielMajeri](https://github.com/GabrielMajeri) and [@nicholasbishop](https://github.com/nicholasbishop)</span>
+
+The `uefi` crate provides safe and performant wrappers for [UEFI](https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface), the successor to the BIOS.
+
+We merged the following changes in May:
+
+#### Improvements
+
+- [Change logger max level to be set by feature](https://github.com/rust-osdev/uefi-rs/pull/429)
+- [Release new versions of the crates](https://github.com/rust-osdev/uefi-rs/pull/432) <span class="gray">(published `uefi v0.16.0`, `uefi-macros v0.7.0`, and `uefi-services v0.13.0`)</span>
+- [Implement `Deref` and `DerefMut` for `ScopedProtocol`](https://github.com/rust-osdev/uefi-rs/pull/434)
+- [Implement `core::fmt::Write` for `Serial`](https://github.com/rust-osdev/uefi-rs/pull/437)
+- [Add documentation links](https://github.com/rust-osdev/uefi-rs/pull/426)
+
+#### Fixes
+
+- [Fix an accidental `*const` conversion](https://github.com/rust-osdev/uefi-rs/pull/423)
+- [Fix compilation of the xtask package under Windows and add to CI](https://github.com/rust-osdev/uefi-rs/pull/438)
+- [Switch back to automatic `Debug` derive for `Header` struct](https://github.com/rust-osdev/uefi-rs/pull/435)
+- [Check table version before calling UEFI 2.0+ functions](https://github.com/rust-osdev/uefi-rs/pull/436)
+
+Thanks to [@JonahPlusPlus](https://github.com/JonahPlusPlus), [@raccog](https://github.com/raccog), and [@verticalegg](https://github.com/verticalegg) for their contributions!
+
+### [`bootloader`](https://github.com/rust-osdev/bootloader)
+
+<span class="maintainers">Maintained by [@phil-opp](https://github.com/phil-opp), [@rybot666](https://github.com/rybot666), and [@64](https://github.com/64)</span>
+
+The `bootloader` crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we merged the following new feature:
+
+- [Add UEFI PXE support](https://github.com/rust-osdev/bootloader/pull/237) to load a kernel from a TFTP server
+
+This feature will be part of the upcoming `v0.11` release. Thanks to [@Freax13](https://github.com/Freax13) for this contribution!
+
+### [`pci_types`](https://github.com/rust-osdev/pci_types)
+
+The `pci_types` library provides types for accessing and configuring PCI devices from Rust operating systems. Lots of this code (e.g. identifying devices by class codes) can be shared
+between projects, and would benefit from community contributions.
+
+We merged the following change in May:
+
+- [PCI capabilities and status register support](https://github.com/rust-osdev/pci_types/pull/3)
+
+Thanks to [@alesharik](https://github.com/alesharik) for this contribution!
+
+### [`xhci`](https://github.com/rust-osdev/xhci)
+
+<span class="maintainers">Maintained by [@toku-sa-n](https://github.com/toku-sa-n)</span>
+
+The `xhci` crate provides types of xHCI structires, such as Registers and TRBs.
+
+We merged the following fix this month:
+
+- [fix(StructuralParameters2): Bit range in `max_scratchpad_buffers_hi`](https://github.com/rust-osdev/xhci/pull/134) <span class="gray">([published](https://github.com/rust-osdev/xhci/pull/135) as `v0.8.4`)</span>
+
+Thanks to [@Yuna-Tomi](https://github.com/Yuna-Tomi) for this contribution!
