Release rayon 1.4.1 (2020-09-29)

• The new flat_map_iter and flatten_iter methods can be used to flatten sequential iterators, which may perform better in cases that don't need the nested parallelism of flat_map and flatten.
• The new par_drain method is a parallel version of the standard drain for collections, removing items while keeping the original capacity. Collections that implement this through ParallelDrainRange support draining items from arbitrary index ranges, while ParallelDrainFull always drains everything.
• The new positions method finds all items that match the given predicate and returns their indices in a new iterator.

Release rayon-core 1.8.1 (2020-09-17)

• Fixed an overflow panic on high-contention workloads, for a counter that was meant to simply wrap. This panic only occurred with debug assertions enabled, and was much more likely on 32-bit targets.

Release rayon 1.4.0 / rayon-core 1.8.0 (2020-08-24)

• Implemented a new thread scheduler, RFC 5, which uses targeted wakeups for new work and for notifications of completed stolen work, reducing wasteful CPU usage in idle threads.
• Implemented IntoParallelIterator for Range<char> and RangeInclusive<char> with the same iteration semantics as Rust 1.45.
• Relaxed the lifetime requirements of the initial scope closure.
