The broadcast channel internally calls clone on the stored value when receiving it, and only requires T:Send. This means that using the broadcast channel with values that are Send but not Sync can trigger unsoundness if the clone implementation makes use of the value being !Sync.
Thank you to Austin Bonander for finding and reporting this issue.
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).
