Release Notes for cardano-cli (10.2.0.0 to 10.4.0.0)

Main changes

• Added cardano-cli latest query ledger-peer-snapshot for a snapshot of big ledger peers used when syncing in Genesis
  (feature)
  PR 727

  A new query subcommand ledger-peer-snapshot was introduced to serialize a snapshot of big ledger peers. These relays will be relied on by network layer when a node is syncing up in Genesis consensus mode, since a node may not have any or up to date information from its own ledger which are the big ledger peer relays.

• Added the debug check-node-configuration --node-configuration-file node-config.json command
  that reads node-config.json and checks that the hashes of genesis files are correct.
  (feature)
  PR 923 based on ADR 5

• Added anchor data hash checks to transaction build
  (feature)
  PR 951

  This version adds a built-in check that allows cardano-cli to verify anchor data linked by a transaction at the time it is being built if using the command transaction build. The cardano-cli will automatically try to download the referenced anchor data, hash it, and check the obtained hash against the one in the transaction, letting the user know if there is a mismatch.
