• tracing: avoid huge trace span names (#3074).

Added

• net: TcpSocket::reuseport(), TcpSocket::set_reuseport() (#3083).
• net: TcpSocket::reuseaddr() (#3093).
• net: TcpSocket::local_addr() (#3093).

Tokio v0.3.2

Adds AsyncFd as a replacement for v0.2's PollEvented.

• sync: oneshot::Sender::poll_closed() (#3032).

Tokio v0.3.1

This release fixes a use-after-free in the IO driver. Additionally, the read_buf and write_buf methods have been added back to the IO traits, as the bytes crate is now on track to reach version 1.0 together with Tokio.

Fixed

• net: fix use-after-free (#3019).
• fs: ensure buffered data is written on shutdown (#3009).

Added

• io: copy_buf() (#2884).

• rt: Runtime::spawn_blocking() (#2980).
• sync: watch::Sender::is_closed() (#2991).

Tokio v0.3.0

This represents a 1.0 beta release. APIs are polished and future-proofed. APIs not included for 1.0 stabilization have been removed.

Biggest changes are:

• I/O driver internal rewrite. The windows implementation includes significant changes.
• Runtime API is polished, especially with how it interacts with feature flag
