Confluent Intelligence likely was the biggest announcement. It’s a combination of three products:

wal3 uses a cryptographic hash to create a setsum of the data in the log. This setsum is an associative and commutative hash function that is used to verify the integrity of the log. Because of the way the hash function is constructed, it is possible to compute a new setsum from an existing setsum and the setsum of a new fragment. This allows us to get cryptographic-strength integrity checking of the log. We go into this at length in the verifiability section below.
