This release delivers full Windows support, and incremental improvements to the node in Byron mode, including improvements in logging, reduced disk I/O and network error handling improvements.
Most of the current development focus is on the Shelley mode. This release includes the initial integration of the Shelley ledger and Ourboros Praos consensus within the node. The Shelley features are not available in the Byron mode, and so not available on the Cardano mainnet. For the curious: following releases will include the CLI tools needed to run the node in Shelley mode locally.
Deployed on the mainnet on 28 April 2020.

This is another cumulative release of the new Cardano node. Since the 1.3.0 release there has been continued development and improvements in all the layers, particularly in the consensus layer.
The most user visible improvements are that the memory use is now stable and the syncing performance is significantly improved compared to earlier releases, and compared to the old cardano-sl
node.
Nodes were deployed on the mainnet on 5th February 2020. These nodes are supporting the use of the new explorer backend by exchanges and other partners. These nodes are not yet being used to create blocks. The migration of the core block-producing nodes to this new cardano-node
implementation will become possible after the Ouroboros BFT hard fork.

The first release of new implementation of the Cardano node
Represents complete rewrite compared to cardano-sl
Has new modular design. The cardano-node is the top level for the node and aggregates the other components from other packages: consensus, ledger and networking, with configuration, CLI, logging and monitoring
Compatible with the Byron mainnet. It can validate blocks from Ouroboros Classic and create blocks after the BFT hard fork
The node no longer incorporates wallet or explorer functionality. The wallet backend and explorer backend are separate components; these run in separate external processes that communicate with the node via local IPC
