+This release adds a check to verify that V5 transactions in the mempool have the correct consensus branch ID; 
+Zebra would previously accept those and return a transaction ID (indicating success) even though they would
+be eventually rejected by the block consensus checks. Similarly, Zebra also now returns an error when trying
+to submit transactions that would eventually fail some consensus checks (e.g. double spends) but would also 
+return a transaction ID indicating success.  The release also bumps
 Zebra's initial minimum protocol version such that this release of Zebra will always reject connections with peers advertising
 a network protocol version below 170,120 on Mainnet and 170,110 on Testnet instead of accepting those connections until Zebra's
 chain state reaches the NU6 activation height.
+The `getblock` RPC method has been updated and now returns some additional information
+such as the block height (even if you provide a block hash) and other fields as supported
+by the `getblockheader` RPC call.
