1.47.0 (July 25th, 2025)

This release adds poll_proceed and cooperative to the coop module for
cooperative scheduling, adds SetOnce to the sync module which provides

This release fixes incorrect spawn locations in runtime task hooks for tasks spawned using tokio::spawn rather than Runtime::spawn. This issue only effected the spawn location in TaskMeta::spawned_at, and did not effect task locations in Tracing events.

1.45.1 (May 24th, 2025)

This fixes a regression on the wasm32-unknown-unknown target, where code that previously did not panic due to calls to Instant::now() started failing. This is due to the stabilization of the first time-based metric.

Fixed

This release fixes a soundness issue in the broadcast channel. The channel
accepts values that are Send but !Sync. Previously, the channel called
clone() on these values without synchronizing. This release fixes the channel
by synchronizing calls to .clone() (Thanks Austin Bonander for finding and
reporting the issue).

Compare Source

1.44.0 (March 7th, 2025)

This release changes the from_std method on sockets to panic if a blocking socket is provided. We determined this change is not a breaking change as Tokio is not intended to operate using blocking sockets. Doing so results in runtime hangs and should be considered a bug. Accidentally passing a blocking socket to Tokio is one of the most common user mistakes. If this change causes an issue for you, please comment on #​7172.

Added
