# 0.2.0 (November 26, 2019)
A major breaking change. Most implementation and APIs have changed one way or
another. This changelog entry contains a highlight
### Changed
- APIs are updated to use `async / await`.
- most `tokio-*` crates are collapsed into this crate.
- Scheduler is rewritten.
- `tokio::spawn` returns a `JoinHandle`.
- A single I/O / timer is used per runtime.
- I/O driver uses a concurrent slab for allocating state.
- components are made available via feature flag.
- Use `bytes` 0.5
- `tokio::codec` is moved to `tokio-util`.
### Removed
- Standalone `timer` and `net` drivers are removed, use `Runtime` instead
- `current_thread` runtime is removed, use `tokio::runtime::Runtime` with
`basic_scheduler` instead.
# 0.1.21 (May 30, 2019)
### Changed
- Bump `tokio-trace-core` version to 0.2 (#1111).

### Added
- `tokio::runtime::Builder::panic_handler` allows configuring handling
panics on the runtime (#1055).
# 0.1.19 (April 22, 2019)
### Added
- Re-export `tokio::sync::Mutex` primitive (#964).
