0.3.31 - 2024-10-05

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)
Fix parsing issue in select!/select_biased! (#2832) This is technically a breaking change as it will now reject a very odd undocumented syntax that was previously accidentally accepted.
Work around issue due to upstream Waker::will_wake change (#2865)
Add stream::Iter::{get_ref,get_mut,into_inner} (#2875)
Add future::AlwaysReady (#2825)
Relax trait bound on non-constructor methods of io::{BufReader,BufWriter} (#2848)
