Tokio v0.2.18

on GitHub

Fixes a regression with LocalSet that allowed !Send futures to cross threads.

This change makes LocalSet !Send. The Send implementation was accidentally added in v0.2.14. Removing the Send implementation is not considered a breaking change as it fixes a soundness bug and the implementation was accidental.

Fixes

• task: LocalSet was incorrectly marked as Send (#2398)
• io: correctly report WriteZero failure in write_int (#2334)
