- Replace-By-Fee Cooperative Close is a new cooperative channel close mechanism, which addresses an oft-requested protocol update enabling the channel closing peer to pay for the closing transaction, along with the flexibility for either peer to increase the transaction fee via RBF.
- Migration of Invoices to Native SQL helps to reduce LND startup time by allowing existing LND users to migrate their Invoice data from kvdb store to native SQL schema.
- Improved payment reliability, driven by optimized pathfinding, now powered by more accurate probability estimates from our bimodal model.
- Testnet4 support for LND, to provide a more stable environment for testing without the block storms that have affected testnet3.
I'm really looking forward to a well functioning postgres db for LND. Shouldn't be too hard to advocate for using expiring locks for master selection and give node runners relatively trivial HA.
