this requires you to install [`cargo-release`]. note that this does not include a URL pointing to the diff on GitHub as is usually done in changelogs since `embassy` is a mono-repo and the GH UI doesn't offer a commit view per folder (see the [GH feature request] for this).

Embassy RP HAL
HALs implement safe, idiomatic Rust APIs to use the hardware capabilities, so raw register manipulation is not needed.
The embassy-rp HAL targets the Raspberry Pi RP2040 as well as RP235x microcontroller. The HAL implements both blocking and async APIs for many peripherals. The benefit of using the async APIs is that the HAL takes care of waiting for peripherals to complete operations in low power mode and handling interrupts, so that applications can focus on more important matters.
embassy-time time driver
If the time-driver feature is enabled, the HAL uses the TIMER peripheral as a global time driver for embassy-time, with a tick rate of 1MHz.
Embedded-hal
The embassy-rp HAL implements the traits from embedded-hal (v0.2 and 1.0) and embedded-hal-async, as well as embedded-io and embedded-io-async.
Interoperability
This crate can run on any executor.
Optionally, some features requiring embassy-time can be activated with the time-driver feature. If you enable it,
you must link an embassy-time driver in your project.
