+# 1.42.1 (April 7nd, 2025)
+
+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).
+
+### Fixed

+- sync: synchronize `clone()` call in broadcast channel ([#7232])
