##0.7.37

• Deprecations

  1. Removed humanistic amount detection in transaction.payment. Passing 1XRP as the payment amount no longer works.
  2. remote.setServer uses full server URL rather than hostname. Example: remote.setServer('wss://s.ripple.com:443')`
  3. Removed constructors for deprecated transaction types from transaction.js.
  4. Removed invoiceID option from transaction.payment. Instead, use the transaction.invoiceID method.
  5. Removed transaction.transactionManager getter.

• Improved multi-server support. Servers are now ranked dynamically, and transactions are broadcasted to all connected servers.

• Automatically ping connected servers. Client configuration now should contain ping: <seconds> to specify the ping interval.

• Added transaction.lastLedger to specify LastLedgerSequence. Setting it this way also ensures that the sequence is not bumped on subsequent requests.

• Added optional remote.accountTx binary parsing.

    {
      binary: true,
      parseBinary: false
    }
  

• Improve test coverage

• Added blob vault client. The vault client facilitates interaction with ripple's namespace and blob vault or 3rd party blob vaults using ripple's blob vault software (https://github.com/ripple/ripple-blobvault). A list of the available functions can be found at docs/VAULTCLIENT.md

##0.7.35

• LastLedgerSequence is set by default on outgoing transactions. This refers to the last valid ledger index (AKA sequence) for a transaction. By default, this index is set to the current index (at submission time) plus 8. In theory, this allows ripple-lib to deterministically fail a transaction whose submission request timed out, but whose associated server continues to emit ledger_closed events.

• Transactions that err with telINSUF_FEE_P will be automatically resubmitted. This error indicates that the Fee supplied in the transaction submission request was inadquate. Ideally, the Fee is tracked by ripple-lib in real-time, and the resubmitted transaction will most likely succeed.

• Added Transaction.iff(function(callback) { }). Callback expects first argument to be an Error or null, second argument is a boolean which indicates whether or not to proceed with the transaction submission. If an iff function is specified, it will be executed prior to every submission of the transaction (including resubmissions).

• Transactions will now emit presubmit and postsubmit events. They will be emitted before and after a transaction is submitted, respectively.

• Added Transaction.summary(). Returns a summary of a transaction in semi-human-readable form. JSON-stringifiable.

• Remote.requestAccountTx() with binary: true will automatically parse transactions.

• Added Remote.requestAccountTx filter, map, and reduce.

  remote.requestAccountTx({
    account: 'retc',
    ledger_index_min: -1,
    ledger_index_max: -1,
    limit: 100,
    binary: true,

    filter: function(transaction) {
      return transaction.tx.TransactionType === 'Payment';
    },

    map: function(transaction) {
      return Number(transaction.tx.Amount);
    },

    reduce: function(a, b) {
      return a + b;
    },

    pluck: 'transactions'
  }, console.log)

• Added persistence hooks.

• General performance improvements, especially for long-running processes.
