Support /accounts?liquidity_pool={:pool_id} and update the response from /accounts/{:acc_id}

Update

  • A new type of trustline called liquidity_pool_shares was added, which is included in the account balances array and causes a breaking change (see below) (#688).
  • Clients can now filter the results from the /accounts endpoint based on participation in a certain liquidity pool (#688).

Breaking Changes

  • The balances array from an account response now supports liquidity pool balances (#688).
    • the asset_type field can now be liquidity_pool_shares.
    • buying_liabilities, selling_liabilities, asset_code, and asset_issuer are omitted from the response for pool shares because they are not relevant to liquidity pools.
  • Update the ChangeTrustOperationResponse interface so it can conform to a change in a liquidity pool trustline (#688).
    • asset_type can now be liquidity_pool_shares.
    • asset_code and asset_issuer are now optional.
    • Added liquidity_pool_id as an optional field.
