 Fixes
 -----
 
-**FAB-XXXXX: component - fix title**
+**peer and orderer PKCS#11 - Always Finalize the PKCS#11 FindObject Operation**
+
+In certain error paths, a PKCS#11 session was not finalized, leaving the session
+in a locked state so that it could not be reused.
+This fix finalizes session handles even in error paths, so that the session can be reused
+by subsequent calls.
+
+**orderer - Allow tick interval override via orderer.yaml**
+
+If a raft network becomes unstable, sometimes, adjusting the tick
+interval duration can be effective to restore it. However, the tick interval is
+stored in the channel configuration, so if the network is not operational,
+modifying it is very challenging. This fix adds Consensus.TickIntervalOverride
+option to orderer.yaml configuration, allowing the channel configuration parameter
+to be overridden from the local configuration.
+
+**FAB-18244: orderer - Single node orderer will not start due to inconsistent state**
+
+If using a single node orderer, it was possible to get into an inconsistent state where
+a Raft WAL snapshot was taken but an in-flight block at the associated height is not yet written.
+This fix resolves the inconsistent state by writing the last block, so that the
+single node orderer can start.
+
+**orderer - Remove duplicate orderer server TLS root CAs**
+
+This fix reduces processing overhead when an ordering service node participates
+in many channels.
+
+**peer - incorrect handling of values set to empty byte array in node chaincode**
 
-Fix description
+Peer should handle key values set to nil or empty byte arrays as a delete of the key.
+While the behavior worked as expected when using Go chaincode and Java chaincode, if using
+node chaincode it did not work correctly when setting key values to empty byte arrays.
+This fix ensures that peer will interpret empty byte arrays as deletes even for node chaincodes.
+If using node chaincode with private data, if you had set private data values to an empty byte array,
+the private data hash would have been committed incorrectly to the state database.
+To repair the state database, after applying the fix, with the peer stopped,
+request that the state database be rebuilt by calling "peer node rebuild-dbs"
+or by deleting the state database. Upon the next start, the peer will rebuild the state
+database from the already processed block store.
+If subsequent transactions had referenced the existence of such a private data hash by
+calling GetPrivateDataHash, then the subsequent transactions may have been
+processed incorrectly and the peer will need to additionally reprocess blocks,
+which can be triggered by calling "peer node reset" instead of "peer node rebuild-dbs".
+If using regular channel data only and not private data, the empty byte array will
+not have been committed, and therefore no action is required on the peer beyond applying the fix.
