## Unreleased

## 0.4.0 - 2023-12-05

- Removed `arch-xtensa`. Use the executor provided by the HAL crate (`esp-hal`, `esp32s3-hal`, etc...) instead.
- Added an arena allocator for tasks, allowing using the `main` and `task` macros on Rust 1.75 stable. (it is only used if the `nightly` feature is not enabled. When `nightly` is enabled, `type_alias_impl_trait` is used to statically allocate tasks, as before).

## 0.3.3 - 2023-11-15

- Add `main` macro reexport for Xtensa arch.
- Remove use of `atomic-polyfill`. The executor now has multiple implementations of its internal data structures for cases where the target supports atomics or doesn't.

## 0.3.2 - 2023-11-06

- Use `atomic-polyfill` for `riscv32`
- Removed unused dependencies (static_cell, futures-util)

## 0.3.1 - 2023-11-01

- Fix spurious "Found waker not created by the Embassy executor" error in recent nightlies.

## 0.3.0 - 2023-08-25

- Replaced Pender. Implementations now must define an extern function called `__pender`.
- Made `raw::AvailableTask` public
- Made `SpawnToken::new_failed` public
- You can now use arbitrary expressions to specify `#[task(pool_size = X)]`

## 0.2.1 - 2023-08-10
