  • v1.11.0 Changes

    March 22, 2022

    ๐Ÿš€ This release improves compile times by up to 55% on initial builds, and up to 75% on recompilation. Additionally we've added a few new APIs and made some tweaks.

    โž• Added

    • TcpListener::into_incoming to convert a TcpListener into a stream of incoming TCP connections

    โœ‚ Removed

    • ๐Ÿ“š The internal extension_trait macro had been removed. This drastically improves compile times for async-std, but changes the way our documentation is rendered. This is a cosmetic change only, and all existing code should continue to work as it did before.

    ๐Ÿ”„ Changed

    • Some internal code has been de-macro-ified, making for quicker compile times.
    • 0๏ธโƒฃ We now use the default recursion limit.

    ๐Ÿ“„ Docs

    • ๐Ÿ›  Several docs improvements / fixes.
  • v1.10.0 Changes

    August 25, 2021

    ๐Ÿš€ This release comes with an assortment of small features and fixes.

    โž• Added

    • ๐Ÿ‘ฏ File now implements Clone so that Files can be passed into closures for use in spawn_blocking.
      • File's contents are already wrapped in Arcs, so the implementation of Clone is straightforward.
    • task::try_current() which returns a handle to the current task if called within the context of a task created by async-std.
    • async_std::io now re-exports WriteExt directly.

    ๐Ÿ›  Fixed

    • write! now takes already written bytes into account on File.

    Internal

    • TcpStream now properly makes use of vectored IO.
    • The net::*::Incoming implementations now do less allocation.

    ๐Ÿ“„ Docs

    • ๐Ÿ›  Several docs improvements / fixes.
  • v1.9.0 Changes

    January 15, 2021

    ๐Ÿšš This patch stabilizes the async_std::channel submodule, removes the ๐Ÿ”€ deprecated sync::channel types, and introduces the tokio1 feature.

    ๐Ÿ†• New Channels

    ๐Ÿš€ As part of our 1.8.0 release last month we introduced the new ๐Ÿ—„ async_std::channel submodule and deprecated the unstable ๐Ÿ”€ async_std::sync::channel types. You can read our full motiviation for this ๐Ÿ”„ change in the last patch notes. But the short version is that the old ๐Ÿ”€ channels had some fundamental problems, and the sync submodule is a bit of a mess.

    ๐Ÿš€ This release of async-std promotes async_std::channel to stable, and ๐Ÿ”€ fully removes the async_std::sync::channel types. In practice many โฌ†๏ธ libraries have already been upgraded to the new channels in the past month, and this will enable much of the ecosystem to switch off "unstable" versions of async-std.

    use async_std::channel;
    
    let (sender, receiver) = channel::unbounded();
    
    assert_eq!(sender.send("Hello").await, Ok(()));
    assert_eq!(receiver.recv().await, Ok("Hello"));
    

    Tokio 1.0 compat

    ๐Ÿš€ The Tokio project recently released version 1.0 of their runtime, and the async-std team would like to congratulate the Tokio team on achieving this milestone.

    ๐Ÿš€ This release of async-std adds the tokio1 feature flag, enabling Tokio's TLS constructors to be initialized within the async-std runtime. This is in โž• addition to the tokio02 and tokio03 feature flags which we were already exposing.

    In terms of stability it's worth noting that we will continue to provide ๐Ÿ‘Œ support for the tokio02, tokio03, and tokio1 on the current major ๐Ÿš€ release line of async-std. These flags are part of our public API, and ๐Ÿ‘ removing compat support for older Tokio versions is considered a breaking ๐Ÿ”„ change.

    • ๐Ÿ”’ Migrated RwLock and Barrier to use the async-lock crate internally (#925)
    • Replaced uses of deprecated the compare_and_swap method with compare_exchange (#927)
  • v1.8.0 Changes

    December 04, 2020

    This patch introduces async_std::channel, a new submodule for our async channels implementation. channels have been one of async-std's most requested features, and have existed as "unstable" for the past year. We've been cautious about stabilizing channels, and this caution turned out to be warranted: we realized our channels could hang indefinitely under certain circumstances, and people ended up expressing a need for unbounded channels.

    So today we're introducing the new async_std::channel submodule which exports the async-channel crate, and we're marking the older unstable async_std::sync::channel API as "deprecated". This release includes both APIs, but we intend to stabilize async_std::channel and remove the older API in January. This should give dependent projects a month to upgrade, though we can extend that if it proves to be too short.

    ๐Ÿ”€ The rationale for adding a new top-level channel submodule, rather than extending sync is that the std::sync and async_std::sync submodule are a bit of a mess, and the libs team [has been talking about splitting std::sync up](https://github.com/rust-lang/rfcs/pull/2788#discussion_r339092478) into separate modules. The stdlib has to guarantee it'll forever be backwards compatible, but async-std does not (we fully expect a 2.0 once we have async closures & traits). So we're experimenting with this change before std does, with the expectation that this change can serve as a data point when the libs team decides how to proceed in std.
