v1.17.0

This release primarily focuses on ability to support better DeFi projects alongwith some value addition for existing clients by bringing in 10 new endpoints (paired with 2 deprecations), few additional optional input parameters , and some additional output columns to existing endpoints. The only breaking change/fix is for output returned for tx_info.

Also, dbsync 13.1.0.x has been released and is recommended to be used for this release. It is recommended you shutdown services temporarily while you upgrade, and perhaps better off re-synching from genesis for preview/preprod as the recreation of indexes are not as optimal as fresh-ly created ones for postgres tiling point of view.

This release is meant to be used for non-mainnet (guild,preview and preprod) networks.

Deprecations

• /asset_address_list - Renamed to asset_addresses keeping naming line with other endpoints (old endpoint will be retired in future release)
• /asset_policy_info - Renamed to policy_asset_info keeping naming line with other endpoints (old endpoint will be retired in future release)

New Endpoints

• /asset_addresses - Equivalent of deprecated /asset_address_list #110
• /asset_nft_address - Returns address where the specified NFT sits on #110
• /account_utxos - Returns brief details on non-empty UTxOs associated with a given stake address #110
• /asset_info_bulk - Bulk version of /asset_info #110
• /asset_token_registry - Returns assets registered via token registry on github #110
• /credential_utxos - Returns UTxOs associated with a payment credential #110
• /param_updates - Returns list of parameter update proposals applied to the network #110
• /policy_asset_addresses - Returns addresses with quantity for each asset on a given policy #110
• /policy_asset_info - Equivalent of deprecated /asset_policy_info but with more details in output #110
• /policy_asset_list - Returns list of asset under the given policy (including supply) #110

Data Input/Output Changes

• Input - /account_addresses - Add optional _first_only and _empty flags to show only first address with tx or to include empty addresses to output #110
• Input - /epoch_info - Add optional _include_next_epoch field to show next epoch stats if available (eg: nonce, active stake) #110
• Output (addition) - /account_assets , /address_assets , /address_info, /tx_info, /tx_utxos - Add decimals to output #110
• Output (addition) - /policy_asset_info - Add minting_tx_hash, total_supply, mint_cnt, burn_cnt and creation_time fields to the output #110
• Output (breaking) - /tx_info - Change _invalid_before and _invalid_after to text field #110
• Output (breaking/removal) - tx_info - Remove the field plutus_contracts > [array] > outputs as there is no logic to connect it to inputs spending #110
