# Changes in 0.1.4
* Add defmt feature, deriving defmt::Format where it makes sense.
# Changes in 0.1.3
* Update heapless dependency.
While this change may be observable to those who attempt to downcast the heapless item returned through an `impl Trait` return,
that change is not regarded as breaking
(for this is the very kind of change such a return is there to allow).
* Update README.
# Changes in 0.1.2
* Added `downcast` feature providing a `downcast_from` method to readable and writable messages based on coap-message 0.3.2 features.
* Fixed read view of options of writable message to not emit spurious empty options.
# Changes in 0.1.1
* Added alloc feature / heap::HeapMessage implementation.
# Changes in 0.1.0
* Moved out of coap-message-utils.
