Version/4.16.1

Changelog

Changed

• Read the node's lowest available block height from the Tendermint RPC
  /status endpoint (sync_info.earliest_block_height) instead of probing
  the LCD and parsing its error message. This requires the new VUE_APP_RPC
  environment variable pointing at the node's RPC. VUE_APP_FIRST_HEIGHT is
  removed: when the RPC is unreachable the explorer now surfaces an error,
  with no fallback
