Release Date: 2018-07-30 // over 5 years ago
    • The changelog is back!
    • ✅ Compatiblity with futures API in latest nightly
    • Code examples and doc improvements
      • IO: Methods of traits AsyncReadExt, AsyncWriteExt
      • Future:
      • Methods of trait TryFutureExt
      • Free functions empty, lazy, maybe_done, poll_fn and ready
      • Type FutureOption
      • Macros join!, select! and pending!
      • Stream: Methods of trait TryStreamExt
    • Added TryStreamExt combinators map_ok, map_err, err_into, try_next and try_for_each
    • ➕ Added Drain, a sink that will discard all items given to it. Can be created using the drain function
    • 🛠 Bugfix for the write_all combinator
    • AsyncWrite impl for Cursor<T: AsMut<[u8]>>
    • FuturesUnordered optimization: Since the context stores a &LocalWaker reference, it was possible to avoid cloning the Arc of the waker
    • Futures-rs now uses Clippy
    • We now use in-band lifetimes
    • The join! and select! macros are now exposed by the futures-preview crate
    • The project logo was added to the README.md
    • 📌 sink::MapErr::get_pinned_mut is now called get_pin_mut
    • We now use the unstable use_extern_macros feature for macro reexports
    • 🍎 CI improvements: Named CI jobs, tests are now run on macOS and Linux, the docs are generated and Clippy needs to pass
    • 🚚 #[deny(warnings)] was removed from all crates and is now only enforced in the CI
    • We now have a naming convention for type paramters: Fut future, F function, St stream, Si sink, S sink & stream, R reader, W writer, T value, E error
    • 🔨 "Task" is now defined as our term for "lightweight thread". The code of the executors and FuturesUnordered was refactored to align with this definition.
