+# The Embedded Working Group Newsletter - 8
+
+> 2018-07-29
+
+This is the eighth 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.

+
+## Highlights
+
+* [libm], the `no_std` port of MUSL's math library led by [japaric] has finished its' first release! It can now be used by embedded (or `wasm`!) targets that need support for math functions.
+* [droogmic] is working on [microrust], a port of [japaric]'s Discovery book for the BBC MicroBit, based on the Nordic nRF51
+* [Hideki Sekine] and [Vaishali Thakkar] have landed initial support for an [Embedded CI Harness] in the [`rust-lang/rust`] repo as part of the [Increasing Rust's Reach] project. This opens the door for tests that will help prevent regressions in `rustc` and `cargo` for ARM Cortex-M targets
+* [CMSIS intrinsics] for ARM Cortex processors have landed in [stdsimd]. Check out the [the docs] in nightly soon<sup>†</sup> for info, thanks to [Paolo Teti] and [japaric]!
+* [Ashley Williams] released [cargo-generate], a CLI tool for generating Cargo projects from a template, reducing the need to manually write boilerplate code. If you write some embedded templates, [let us know]!
+
+†: The CMSIS intrinsics will show up in the docs after the next successful nightly build (after 2018-07-30)

+## Help Wanted
+
+* The Embedded-WG is looking for someone to write an [RFC for ARM Intrinsics] to get them stabilized
+* [Jonathan Pallant] is looking for ideas to implement for the Monotron project. Check out the [monotron blog post] for more details!
+* The [libm] project is looking for help with [refactoring] in order to better support chips without hardware double-floating-point support
