Upgrade instructions

Changelog

• Tested with cardano-node 9.1.0 and cardano-cli 9.2.1.0.

• New landing page and updated documentation style. #1560

• Fixed pruning of transactions when a snapshot is requested:

  • Before, the hydra-node would re-apply transactions in the wrong order which made already "seen" transactions (indicated by TxValid) disappear from the local ledger state and also not get snapshotted.
  • Details in #1559

• Add TLS support for the API server via --tls-cert and --tls-key command line options. #1555

Contributors

• @fstoqnov-iohk made their first contribution in #1549
