Cardano Explorer 1.3.0

This Cardano Explorer release resolves a number of issues, improves documentation and makes use of the latest library updates. Importantly it has a change in the API for transaction submission in the cardano-tx-submit component. There is new Cardano Explorer API documentation.

Compatible with Cardano node 1.5.0.

Deployed 5 Feb 2020.

Improvements

• API change in cardano-tx-submit for transaction submission. It now requires
  • the HTTP content-type to be given as application/cbor
  • the transaction format must be the raw binary transaction as it appears on the chain
• Added more specific error message when a posted transaction is hex encoded
• Included example of testnet configuration and updated README on how to use it
• Documented submission API and how to generate example transactions
• Updated docker image with logging all runit services to stdout
• Added validation for genesis address paging (#219)
• Created Swagger Cardano Explorer API documentation https://input-output-hk.github.io/cardano-explorer/

Resolved issues

• /api/blocks/txs/{blkHash} endpoint (#195)
• Ada/Lovelace denomination issue (#197)
• JSON rendering for addresses to match old API
• /api/genesis/address returns the same addresses for different pages (#183)

Known Issues

• The pageSize argument is hard coded to be 10 (#182). This will not be fixed, but there will be a new better-designed set of explorer APIs in a future release.
