AI Summary

Key Highlights

  • Fixed soundness issue in broadcast channel
  • Synchronized calls to `.clone()` to prevent data races

Full Release Notes

This release fixes a soundness issue in the broadcast channel. The channel accepts values that are `Send` but `!Sync`. Previously, the channel called `clone()` on these values without synchronizing. This release fixes the channel by synchronizing calls to `.clone()` (Thanks Austin Bonander for finding and reporting the issue).
