*Sourced from [cortex-m-rtfm's changelog](https://github.com/rtfm-rs/cortex-m-rtfm/blob/master/CHANGELOG.md).*

> ## v0.5.0 - 2019-11-14
> 
> ### Added
> 
> - Experimental support for homogeneous and heterogeneous multi-core
>   microcontrollers has been added. Support is gated behind the `homogeneous` and
>   `heterogeneous` Cargo features.
> 
> ### Changed
> 
> - [breaking-change][] [RFC 155] "explicit `Context` parameter" has been
>   implemented.
> 
> [RFC 155]: [rtic-rs/rtic#155](https://github-redirect.dependabot.com/rtfm-rs/cortex-m-rtfm/issues/155)
> 
> - [breaking-change][] [RFC 147] "all functions must be safe" has been
>   implemented.
> 
> [RFC 147]: [rtic-rs/rtic#147](https://github-redirect.dependabot.com/rtfm-rs/cortex-m-rtfm/issues/147)
> 
> - All the queues internally used by the framework now use `AtomicU8` indices
>   instead of `AtomicUsize`; this reduces the static memory used by the
>   framework.
> 
> - [breaking-change][] when the `capacity` argument is omitted, the capacity of
>   the task is assumed to be `1`. Before, a reasonable (but hard to predict)
>   capacity was computed based on the number of `spawn` references the task had.
> 
> - [breaking-change][] resources that are appear as exclusive references
>   (`&mut-`) no longer appear behind the `Exclusive` newtype.
> 
> - [breaking-change][] the `timer-queue` Cargo feature has been removed. The
>   `schedule` API can be used without enabling any Cargo feature.
> 
> - [breaking-change][] when the `schedule` API is used the type of
>   `init::Context.core` changes from `cortex_m::Peripherals` to
>   `rtfm::Peripherals`. The fields of `rtfm::Peripherals` do not change when
>   Cargo features are enabled.
> 
> - [breaking-change][] the monotonic timer used to implement the `schedule` API
>   is now user configurable via the `#[app(monotonic = ..)]` argument. IMPORTANT:
>   it is now the responsibility of the application author to configure and
>   initialize the chosen `monotonic` timer during the `#[init]` phase.
> 
> - [breaking-change][] the `peripherals` field is not include in `init::Context`
>   by default. One must opt-in using the `#[app(peripherals = ..)]` argument.
> 
> - [breaking-change][] the `#[exception]` and `#[interrupt]` attributes have been
>   removed. Hardware tasks are now declared using the `#[task(binds = ..)]`
>   attribute.
