This is the 17th changelog for Knurling-rs, our push to sustainably build better tooling for developing and debugging Rust software for embedded systems. Knurling-rs includes a suite of tools that make it easier to develop, log, debug, and test your embedded Rust libraries and applications!

This changelog got delayed to monday, because of the release work for defmt (read more below!).

Knurling-rs is supported by our sponsors on GitHub. If you're interested in seeing more projects like this, consider becoming a sponsor today!

Highlights 🎉

Last friday was a big day release day for the Knurling project, with defmt, defmt-parser, defmt-macros, defmt-decoder, defmt-print, defmt-itm, defmt-rtt, defmt-test, panic-probe and probe-run all maturing to v0.2.0!

There are many great improvements, especially noteworthy:

• We've added the trait defmt::Format for many more types, namely i128, u128, f64, char, std::marker::PhantomData<T>, std::convert::Infallible and core::time::Duration.
• "Display hints" help you by specifying the format in which to display the data you're printing. Find all the details in #270!
• defmt_test features many improvements, for example support for returning Result<T, E>, compatibility for rust-analyzer's "Run Test"-button and a new #[should_error] attribute.
• Overall we did a lot of refactoring and improved much internal code.

Head over to the code editor of your choice and give it a try! 💪
