## [Unreleased]
|
||||
|
||||
- Move dispatchers from extern block to app argument.
|
||||
### Added
|
||||
|
||||
- Allow annotating resources to activate special resource locking behaviour.
|
||||
- `#[lock_free]`, there might be several tasks with the same priority accessing
|
||||
the resource without critical section.
|
||||
- `#[task_local]`, there must be only one task, similar to a task local
|
||||
resource, but (optionally) set-up by init. This is similar to move.
|
||||
|
||||

||||
|
||||
- [breaking-change] [PR 368] `struct Resources` changed to attribute `#[resources]` on a struct.
|
||||
|
||||
- [breaking-change] [PR 368] Mod over const, instead of `const APP: () = {` use `mod app {`.
|
||||
|
||||
- [breaking-change] [PR 372] Init function always return `LateResources` for a symmetric API.
|
||||
|
||||
- [PR 355] Multi-core support was removed to reduce overall complexity.
