 # Changelog
 
+## v0.34.2
+
+*January 12, 2021*
+
+This release fixes a substantial bug in evidence handling where evidence could
+sometimes be broadcast before the block containing that evidence was fully committed,
+resulting in some nodes panicking when trying to verify said evidence.
+
+Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint).
+
