Release Notes

tokio-rs/tokio (tokio)

v1.46.1: Tokio v1.46.1

1.46.1 (July 4th, 2025)

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.

Unstable

• runtime: add TaskMeta::spawn_location tracking where a task was spawned
  (#​7440)
