Release Notes

rust-lang/futures-rs (futures)

v0.3.31

Compare Source

• Fix use after free of task in FuturesUnordered when dropped future panics (#​2886)
• Fix soundness bug in task::waker_ref (#​2830)
  This is a breaking change but allowed because it is soundness bug fix.
• Fix bugs in AsyncBufRead::read_line and AsyncBufReadExt::lines (#​2884)
