+## Announcements, News, and Blog Posts
+
+Here we collect news, blog posts, etc. related to OS development in Rust.
+
+
+- [Announcing Asterinas 0.18.0](https://asterinas.github.io/2026/06/04/announcing-asterinas-0.18.0.html)
+- [This Month in Redox - May 2026](https://www.redox-os.org/news/this-month-260531/)
+ - The latest Redox update covers an EEVDF scheduler, page flipping and plane support in the Intel graphics driver, a COSMIC monitor and XFCE port, and large I/O and RedoxFS performance improvements.
+- [Zinnia](https://zinnia-os.org/)
+ - A Unix-like kernel written almost entirely in Rust that boots on real x86_64 hardware and can run Wayland/X11 desktop sessions (Weston, XFCE). Drivers are loaded as modular Rust ELF libraries at boot.
+- [LearnixOS](https://www.learnix-os.com/)
+ - A book that teaches OS development from scratch in Rust, covering memory allocators, paging, filesystems, and kernel logic.
+- [Hardware Is Asynchronous. Most of Our Operating Systems Still Aren't.](https://vorjdux.com/articles/hardware-is-async.html)
+ - An article arguing that operating systems should treat asynchrony as the default rather than layering it on top of blocking abstractions, drawing on work from [CharlotteOS](https://github.com/charlotte-os/charlotte-os), an experimental modern OS written in Rust.
+- [Building an AsyncIO executor for the 3DS (pt 1!)](https://blog.cat-girl.gay/3ds-async-part-one/)
+ - Building a from-scratch async I/O executor for the Nintendo 3DS.
+

+In this section, we collect recent updates to `rustc`, `cargo`, and other tooling that are relevant to Rust OS development.
+
+
+
+- [Move `std::io::Error` into `core`](https://github.com/rust-lang/rust/pull/155625)
+ - Makes I/O error handling available in `no_std`
+ - Now the rest of `std::io` can be moved to `core`/`alloc` too, including the `Read` and `Write` traits. See the [open PR](https://github.com/rust-lang/rust/pull/156527) and the [tracking issue](https://github.com/rust-lang/rust/issues/154046) for details.

+ - Stabilizes `Box::as_ptr` and `Box::as_mut_ptr`
+ - These methods can be used to create multiple pointers to the same `Box` that don't invalidate each other.
+- [staticlib: hide internal symbols](https://github.com/rust-lang/rust/pull/155338)
+ - A new `-Zstaticlib-hide-internal-symbols` flag hides non-exported Rust symbols in static libraries, shrinking binaries by 5–12% in non-LTO builds.
+- [`asm!` support for the Xtensa architecture](https://github.com/rust-lang/rust/pull/147302)
+ - Inline assembly for Xtensa (ESP32 and related chips) lands in-tree after years in the esp-rs fork.

+### [`bootloader`](https://github.com/rust-osdev/bootloader)
+Maintained by [@phil-opp](https://github.com/phil-opp) and [@Freax13](https://github.com/Freax13)
+
+The `bootloader` crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. The following changes landed in early July, but we want to mention them already because they affect users building against recent Rust nightlies:
+
+- Recent Rust nightlies renamed the `x86-softfloat` target ABI to `softfloat`. This update adjusts the bootloader's custom targets accordingly, on both the latest release and the `v0.9` branch.
+ - [Change `rustc-abi` in custom targets from `x86-softfloat` to `softfloat`](https://github.com/rust-osdev/bootloader/pull/569)

+Maintained by [@phip1611](https://github.com/phip1611)
+
+Simple yet highly configurable low-level driver for 16550 UART devices,
+typically known and used as serial ports or COM ports.
+
+We merged the following change this month:
+
+- [lib: change signature of Uart16550::config() to be more flexible](https://github.com/rust-osdev/uart_16550/pull/61)

+## Other Projects
+
+In this section, we describe updates to Rust OS 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.

+
+### [`mkroening/elf-symbols`](https://github.com/mkroening/elf-symbols)
+(Section written by [@mkroening](https://github.com/mkroening))
+
+When developing an OS, you often need some information about the loaded kernel image:
+
+- Where has the loader loaded the kernel to?
+- How large is the loaded kernel?
+- Where do the text segment and the data segment end?
+- How do I get the kernel TLS image?
+
+These questions can be answered by building non-relocatable images, by writing custom linker scripts, or by having a custom loader that provides this information somehow.
+
+But there is another way!
+In fact, the main ELF linkers that I am aware of ([BFD], [gold], [LLD], [mold], and [Wild]) all have built-in ELF symbols that answer these questions when not using custom linker scripts.
+Unfortunately, many are poorly documented, so I created the [elf-symbols] crate that exposes and documents them.
+All symbols are tested on the aforementioned linkers.
+The documentation shows when each linker gained support for the respective symbol.
+
+The following symbols are straightforward:
+
+- `__executable_start` (`executable_start()`) is the start of the executable.
+- `_etext` (`text_end()`) is the end of the text segment.
+- `_edata` (`data_end()`) is the end of the data segment.
+- `_end` (`executable_end()`) is the end of the executable.
+
+`__ehdr_start` (`elf_header()`) is especially interesting.
+It allows programs to examine themselves by reading their ELF headers (file headers and program headers).
+This can be used to get TLS image information, for example.
+
+Note that these symbols are ELF specific, though, so they cannot be used when linking to something else, such as a PE32+ UEFI executable.
+
+#### Examples
+
+```rust
+println!("Executable start: {:p}", elf_symbols::executable_start());
+println!("ELF header: {:p}", elf_symbols::elf_header());
+println!("Text segment end: {:p}", elf_symbols::text_end());
+println!("Data segment end: {:p}", elf_symbols::data_end());
+println!("Executable end: {:p}", elf_symbols::executable_end());
+```

+### [`phil-opp/blog_os`](https://github.com/phil-opp/blog_os)
+(Section written by [@phil-opp](https://github.com/phil-opp))
+
+We merged the following changes to the [_Writing an OS in Rust_](https://os.phil-opp.com/) blog. These landed in early July, but we mention them here since they keep the code building on the latest Rust nightly:
+
+- [Fix target spec: use `softfloat` instead of `x86-softfloat`](https://github.com/phil-opp/blog_os/pull/1484)
+- [Fix blog: the `x86-softfloat` feature was renamed to `softfloat`](https://github.com/phil-opp/blog_os/pull/1485)
+- [Update for new Rust error messages](https://github.com/phil-opp/blog_os/pull/1486)
+- [Update blog to zola 0.22.1](https://github.com/phil-opp/blog_os/pull/1487)
