This release includes support in the cardano-cli for multi-signature addresses and transactions. It also resolves a problem that has been affecting pool operators at the 48-hour mark within each epoch. It has various other minor improvements and fixes detailed below.
The "Live View" mode for the Cardano node is being deprecated in favour of a new external "RT View" (RT for real-time) monitoring tool which is cross-platform and has a richer browser-based interface. The new RT View component will be released separately. The Live View mode is still available in this release of the node, but will be removed in a future release.
