+# The Embedded Working Group Newsletter - 3
+
+> 2018-04-14
+
+This is the third bi-weekly newsletter of the [Embedded WG] where we highlight new progress, celebrate cool projects, thank the community, and advertise projects that need help!
+
+If you want to mention something in [the next newsletter], make sure to leave a comment on the issue.
+
+[the next newsletter]: https://github.com/rust-lang-nursery/embedded-wg/issues/84
+[Embedded WG]: https://github.com/rust-lang-nursery/embedded-wg
+
+## Highlights
+
+* Crates for the Embedded Rust Ecosystem are now being tracked in the [Awesome Embedded Rust] repository
+* Progress has been made as part of the [Embedded Rust on Stable] initiative, including:
+    * `extern crate compiler_builtins` is [now included in the no_std prelude]
+    * [xargo no longer needed] for ARM Cortex-M development
+* We also made some progress on simplifying the embedded development setup: You can now link Embedded Rust programs [using lld]
+* [Wilfried] kicked off a blog series about [using embedded rust]
+* [Andre Richter] is writing a tutorial for using Rust to write [bare metal Raspberry Pi 3] applications
+* The Embedonomicon and the Embedded Rust Books are [now kept] in the [Embedded WG] repository, and pull requests are welcome!

+## Embedded Projects
+
+If you have an embedded project or blog post you would like to have featured in the Embedded WG Newsletter, make sure to mention it on the tracking issue for [the next newsletter], we would love to show it off!
+
+* [japaric] released an initial version of [cargo-binutils], which will allow you to use LLVM's binutils (like `nm`, `size`, `objcopy`, etc.) in the format `cargo objcopy` (once [issue 49584] has landed)
+* [myeisha] released the first version of their [thumb2-stack-size] tool, which helps determine the maximum stack size used in embedded code

+
+## Help Wanted
+
+* We need help working on [RFC2070], stabilizing usage of custom Panic behavior. [nagisa] is willing to mentor!
+* If you use inline assembly in your Embedded Rust programs, help us capture what assembly operations are [used most often] so we can stabilize them as intrinsics
+
