 # Changelog
 
+## v0.31.3
+
+*April 1st, 2019*
+
+This release includes two security sensitive fixes: it ensures generated private
+keys are valid, and it prevents certain DNS lookups that would cause the node to
+panic if the lookup failed.
+
+### BUG FIXES:
+
+- [crypto/secp256k1] [\#3439](https://github.com/tendermint/tendermint/issues/3439)
+    Ensure generated private keys are valid by randomly sampling until a valid key is found.
+    Previously, it was possible (though rare!) to generate keys that exceeded the curve order.
+    Such keys would lead to invalid signatures.
+- [p2p] [\#3522](https://github.com/tendermint/tendermint/issues/3522) Memoize
+  socket address in peer connections to avoid DNS lookups. Previously, failed
+  DNS lookups could cause the node to panic.
+
