`Resource.claim_mut` has been renamed to `Mutex.lock` and its signature has
changed (no `Threshold` token is required).
- [breaking-change] The name of the library has changed to `rtfm`. The package
name is still `cortex-m-rtfm`.
- [breaking-change] `cortex_m_rtfm::set_pending` has been renamed to
`rtfm::pend`.
### Added
- Software tasks, which can be immediately spawn and scheduled to run in the
future.
- `Instant` and `Duration` API.
- Integration with the [`Singleton`] abstraction.
[`Singleton`]: https://docs.rs/owned-singleton/0.1.0/owned_singleton/
### Removed
- [breaking-change] The `Threshold` token has been removed.
- [breaking-change] The `bkpt` and `wfi` re-exports have been removed.
- [breaking-change] `rtfm::atomic` has been removed.
## [v0.3.4] - 2018-08-27
### Changed
- The documentation link to point to GH pages.
## [v0.3.3] - 2018-08-24
### Fixed
- Compilation with latest nightly
## [v0.3.2] - 2018-04-16
### Added
- Span information to error messages
### Changed
- Some non fatal error messages have become warning messages. For example, specifying an empty list
of resources now produces a warning instead of a hard error.
## [v0.3.1] - 2018-01-16
### Fixed
- Documentation link
## [v0.3.0] - 2018-01-15
### Added
- [feat] `&'static mut` references can be safely created by assigning resources to `init`. See the
`init.resources` section of the `app!` macro documentation and the `safe-static-mut-ref` example
for details.
### Changed
- [breaking-change] svd2rust dependency has been bumped to v0.12.0
- [breaking-change] resources assigned to tasks, or to idle, that were not declared in the top
`resources` field generate compiler errors. Before these were assumed to be peripherals, that's no
longer the case.
- [breaking-change] the layout of `init::Peripherals` has changed. This struct now has two fields:
`core` and `device`. The value of the `core` field is a struct that owns all the core peripherals
of the device and the value of the `device` field is a struct that owns all the device specific
peripherals of the device.
## [v0.2.2] - 2017-11-22
### Added
- Support for runtime initialized resources ("late" resources).
## [v0.2.1] - 2017-07-29
### Fixed
- Link to `app!` macro documentation.
## [v0.2.0] - 2017-07-29
### Added
- The `app!` macro, a macro to declare the tasks and resources of an
application.
- The `Resource` trait, which is used to write generic code that deals with
resources.
- Support for system handlers like SYS_TICK.
### Changed
- [breaking-change] The signature of the `atomic` function has changed.
- [breaking-change] The threshold token has become a concrete type and lost its
`raise` method.
### Removed
- [breaking-change] The `tasks!` and `peripherals!` macros.
- [breaking-change] The ceiling and priority tokens.
- [breaking-change] The `Local`, `Resource` and `Peripheral` structs.
- [breaking-change] The traits related to type level integers.
## [v0.1.1] - 2017-06-05
### Changed
