+### [`bootloader`](https://github.com/rust-osdev/bootloader)
+
+The `bootloader` crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we fixed some build errors that were caused by the update to LLVM 12 in recent Rust nightlies:
+
+- [Fix linker errors on latest nightlies](https://github.com/rust-osdev/bootloader/pull/139) <span class="gray">(published as `v0.9.15`)</span>
+- [Replace all remaining `lea`s with `mov` + `offset`](https://github.com/rust-osdev/bootloader/pull/140) <span class="gray">(published as `v0.9.16`)</span>
+
+We also made some good progress on the [UEFI rewrite](https://github.com/rust-osdev/bootloader/pull/130):
+
+- [Set up VESA mode properly instead of hardcoding it](https://github.com/rust-osdev/bootloader/pull/130/commits/7f7fec78ffb7125a7eb0312698714d7897bf9fb9)
+- [Detect actual pixel format instead of hardcoding it (BIOS)](https://github.com/rust-osdev/bootloader/pull/130/commits/58564910a743ec48e6c1b3113151d96c7b54ca63)
+- [Use `quote` crate for creating `Config` struct instead of debug impls](https://github.com/rust-osdev/bootloader/pull/130/commits/f7478eba3034c98bde0c7725ce21a7b56a473d61)
+- [Allow specifying addresses as TOML integers too](https://github.com/rust-osdev/bootloader/pull/130/commits/ba9d943dbb18ef756979f1d2c14df297c1003b45)
+- [Add docs for crate and `Config` struct](https://github.com/rust-osdev/bootloader/pull/130/commits/536e0f6b53b8dcd53b6125c3383dec3bdb7a3cc3)

+
+### [`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 March, we merged these changes:
+
+- [Implement `Clone` for `PageTable`](https://github.com/rust-osdev/x86_64/pull/236) <span class="gray">(published as `v0.13.3`)</span>
+- [Implement more fmt traits for addr types](https://github.com/rust-osdev/x86_64/pull/237) <span class="gray">(published as `v0.13.4`)</span>

+
+### [`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. In March, we merged the following changes:
+
+- [Expose device path types](https://github.com/rust-osdev/uefi-rs/pull/202)
+- [Fix running tests in CI](https://github.com/rust-osdev/uefi-rs/pull/203)
+- [Fix typo in regular.rs](https://github.com/rust-osdev/uefi-rs/pull/204)

 ## Personal Projects
 
 In this section, we describe updates to personal projects that are not directly related to the `rust-osdev` organization. Feel free to [create a pull request](https://github.com/rust-osdev/homepage/pulls) with the updates of your OS project for the next post.
