+* The `min_const_fn` feature [has landed], allowing for stable use of `const fn` functions in an embedded context in the upcoming 1.31 release of Rust!
+* [Frank Pagliughi] has kicked off [`rust-industrial-io`], a crate providing an interface to `libiio` on linux, which is used for communication with industrial sensors and actuators
+* [gregokent] has started development on [`cortex-r-rt`], a runtime crate for Cortex-R processors
+* The HAL Impl crate for the Texas Instruments TM4C123 now [works on 1.30-beta]! **Now is a great time to ensure that your embedded crates will work flawlessly with the 2018 Edition of Rust!**
