High level summary
- Made the 
LocalTxMonitor HasTx cross-era behavior less surprising. - Finalized the tests in 
ouroboros-consensus for the UTXO-HD branch, except the mempool-parallel test which is still failing sometimes. - Fixed an upstream complication in 
quickcheck-state-machine related to Parallel state machines which should allow us for an easier and more understandable setup of the parallel mempool tests. - Drafted parallel state machine testing infrastructure for 
quickcheck-dynamic. Eventually could be used to replace the QSM infra for mempool parallel tests. - Cleaned up the 
Cardano.API.LedgerState module, required for UTXO-HD integration. - We have been working on Node release 8.10. The changes upstream are integrated all the way to Node. Tests and benchmarks are pending. The versions of Consensus, Ledger, and Networking are released, and we will focus next on releasing CLI, API, and finally Node.
