# ripple-lib Release History

Subscribe to [the **ripple-lib-announce** mailing list](https://groups.google.com/forum/#!forum/ripple-lib-announce) for release announcements. We recommend that ripple-lib users stay up-to-date with the latest stable release.

## UNRELEASED

* Expose ripple-address-codec methods. These are static methods on RippleAPI, so you do not need to create a RippleAPI instance.
  * `classicAddressToXAddress` / `xAddressToClassicAddress`
  * `isValidXAddress` / `isValidClassicAddress`
  * `encodeSeed` / `decodeSeed`
  * `encodeAccountID` / `decodeAccountID`
  * `encodeNodePublic` / `decodeNodePublic`
  * `encodeAccountPublic` / `decodeAccountPublic`
  * `encodeXAddress` / `decodeXAddress`

Example 1. Encode an X-address with tag 4294967295:
```js
const RippleAPI = require('ripple-lib').RippleAPI
const xAddress = RippleAPI.classicAddressToXAddress('rGWrZyQqhTp9Xu7G5Pkayo7bXjH4k4QYpf', 4294967295)
console.log(xAddress)
```

Output for Example 1:
```
XVLhHMPHU98es4dbozjVtdWzVrDjtV18pX8yuPT7y4xaEHi
```

Example 2. Encode a test address for use with Testnet or Devnet:
```js
const RippleAPI = require('ripple-lib').RippleAPI
const address = RippleAPI.classicAddressToXAddress('r3SVzk8ApofDJuVBPKdmbbLjWGCCXpBQ2g', 123, true)
console.log(address)
```

Output for Example 2:
```
T7oKJ3q7s94kDH6tpkBowhetT1JKfcfdSCmAXbS75iATyLD
```

Example 3. Decode an X-address:
```js
const RippleAPI = require('ripple-lib').RippleAPI
const address = RippleAPI.xAddressToClassicAddress('XVLhHMPHU98es4dbozjVtdWzVrDjtV18pX8yuPT7y4xaEHi')
console.log(address)
```

Output for Example 3:
```js
{
  classicAddress: 'rGWrZyQqhTp9Xu7G5Pkayo7bXjH4k4QYpf',
  tag: 4294967295,
  test: false
}
```

```

## 1.2.0 (2019-03-19)

This release:

* changes the way you handle errors for the `prepare*` methods.
* improves the `message` field of `RippledError`s.
* allows `Sequence` to be set in the transaction JSON provided to
  `prepareTransaction`.

For details, continue reading:

### [BREAKING CHANGE] `prepare*` methods reject the Promise on error

The `prepare*` methods now always reject the Promise when an error occurs, instead of throwing.

Previously, the methods would synchronously throw on validation errors, despite being asynchronous methods that return Promises.

In other words, to handle errors in the past, you would need to use a try/catch block:

```
// OBSOLETE - no need for try/catch anymore
try {
  api.preparePayment(address, payment, instructions).then(prepared => {
    res.send(prepared.txJSON);
  }).catch(error => {
    // Handle asynchronous error
  });
} catch (error) {
    // Handle synchronous error
}
```

Now, you can rely on the Promise's `catch` handler, which is called with the error when the Promise is rejected:

```
api.preparePayment(address, payment, instructions).then(prepared => {
  res.send(prepared.txJSON);
}).catch(error => {
  // Handle error
});
```

This applies to:
* preparePayment
* prepareTrustline
* prepareOrder
* prepareOrderCancellation
* prepareSettings
* prepareEscrowCreation
* prepareEscrowExecution
* prepareCheckCreate
* prepareCheckCash
* prepareCheckCancel
* preparePaymentChannelCreate
* preparePaymentChannelClaim
* preparePaymentChannelFund

### Improved `RippledError` `message`

Previously, `RippledErrors` (errors from rippled) used rippled's `error` field as the `message`.

Now, the `error_message` field is used as the `message`.

This helps to surface the specific cause of an error.

For example, before:
```
[RippledError(invalidParams, { error: 'invalidParams',
  error_code: 31,
  error_message: 'Missing field \'account\'.',
  id: 3,
  request: { command: 'account_info', id: 3 },
  status: 'error',
  type: 'response' })]
```

After:
```
[RippledError(Missing field 'account'., { error: 'invalidParams',
  error_code: 31,
  error_message: 'Missing field \'account\'.',
  id: 3,
  request: { command: 'account_info', id: 3 },
  status: 'error',
  type: 'response' })]
```

In this case, you can see at a glance that `account` is the missing field.

The `error` field is still available in `errorObject.data.error`.

When `error_message` is not set (as with e.g. error 'entryNotFound'), the `error` field is used as the `message`.

### [BUG FIX] `prepareTransaction` does not overwrite the `Sequence` field

The `prepareTransaction` method now allows `Sequence` to be set in the Transaction JSON object, instead of overwriting it with the account's expected sequence based on the state of the ledger.

Previously, you had to use the `sequence` field in the `instructions` object to manually set a transaction's sequence number.

### New in rippled 1.2.1

As this is the first release of ripple-lib following the release of rippled 1.2.1, we would like to highlight the following API improvements:

1. The [`delivered_amount` field](https://developers.ripple.com/partial-payments.html#the-delivered-amount-field) has been added to the `ledger` method, and to transaction subscriptions.

        api.getLedger({includeTransactions: true, includeAllData: true, ledgerVersion: 17718771}).then(...)

    You can also call `ledger` directly:

        request('ledger', {...}).then(...)

## 1.0.0 (2018-08-30)

We are pleased to announce the release of `ripple-lib` version 1.0.0.

This version features a range of changes and improvements that make the library
more capable and flexible. It includes new methods for accessing rippled APIs,
including subscriptions.

When using this version with `rippled` for online functionality, we recommend
using `rippled` version 1.0.1 or later.

Here is a summary of the changes since `ripple-lib` version 0.22.0, which was
the last non-beta version.

### New Features

+ [Add `request()`, `hasNextPage()`, and `requestNextPage()` for accessing `rippled`
  APIs](https://github.com/ripple/ripple-lib/blob/09541dae86bc859bf5928ac65b2645dfaaf7f8b1/docs/index.md#rippled-apis).
+ Add `prepareTransaction()` for preparing raw `txJSON`.
+ XRP amounts can be specified in drops. Also, `xrpToDrops()` and `dropsToXrp()`
  are available to make conversions.
+ `getTransaction` responses can include a new `channelChanges` property that
  describes the details of a payment channel.

### Data Validation and Errors

+ [Amounts in drops and XRP are checked for
  validity](https://github.com/ripple/ripple-lib/blob/develop/HISTORY.md#100-beta1-2018-05-24).
+ [A maximum fee is now
  imposed](https://github.com/ripple/ripple-lib/blob/develop/HISTORY.md#100-beta2-2018-06-08). Exceeding it causes a `ValidationError` to be
  thrown.
+ Errors are improved and more data validation was added.
+ Bug fix: `getPaths` now filters paths correctly and works correctly when the
  destination currency is XRP.

### Breaking Changes

The following changes were introduced in 1.0.0.

+ `getTransaction()` and `getTransactions()`
  + The `specification.destination.amount` field has been removed from the parsed transaction response.
  + To determine the amount that a transaction delivered, use `outcome.deliveredAmount`.
  + If you require the provisional requested `Amount` from the original transaction:
    + Use `getTransaction`'s `includeRawTransaction` option, or
    + Use `getTransactions`'s `includeRawTransactions` option, or
    + Use the rippled APIs directly with `request`. For example, call the API methods `tx`, `account_tx`, etc.
+ `getLedger()` response object
  + The `rawTransactions` field has been removed (for consistency with `getTransaction()` and `getTransactions()`).
  + Instead, within each `transaction`, use the new `rawTransaction` JSON string.
  + The `metaData` field has been renamed to `meta` for consistency with rippled's `tx` method.
  + `ledger_index` has been added to each raw transaction.

```

## 1.0.0-beta.5 (2018-08-11)

+ [Fix a TypeScript error by importing the `Prepare` type](https://github.com/ripple/ripple-lib/commit/7cd517268bda5fe74b91dad02fedf8b51b7eae9b)

## 1.0.0-beta.4 (2018-08-10)

+ [Add `prepareTransaction()`](https://github.com/ripple/ripple-lib/pull/898)
+ Internal improvements and cleanup

## 1.0.0-beta.3 (2018-07-17)

+ For payment channel transactions, `getTransaction` includes a new
  `channelChanges` property that describes the details of the payment channel.
  (#920)

### Bug Fixes

+ A bug caused calculated fees to use too many decimal places. This was fixed by
  rounding fees to 6 decimal places. (#912)
+ When using the Settings transaction to set up a multi-signing list, the
  threshold and weights fields are required. (#909)
+ Docs: Fix the MIMETYPE in examples with memos. (#914)

```

## 1.0.0-beta.2 (2018-06-08)

### Breaking Changes

+ During transaction preparation, there is now a maximum fee. Also, when a transaction is signed, its fee is checked and an error is thrown if the fee exceeds the maximum. The default `maxFeeXRP` is `'2'` (2 XRP). Override this value in the RippleAPI constructor.
+ Attempting to prepare a transaction with an exact `fee` higher than `maxFeeXRP` causes a `ValidationError` to be thrown.
+ Attempting to sign a transaction with a fee higher than `maxFeeXRP` causes a `ValidationError` to be thrown.
+ The value returned by `getFee()` is capped at `maxFeeXRP`.

### Other Changes

+ In Transaction Instructions, the `maxFee` parameter is deprecated. Use the `maxFeeXRP` parameter in the RippleAPI constructor.

#### Overview of new fee limit

Most users of ripple-lib do not need to make any code changes to accommodate the new soft limit on fees. The limit is designed to protect against the most severe cases where an unintentionally high fee may be used.

+ When having ripple-lib provide the fee with a `prepare*` method, a maximum fee of `maxFeeXRP` (default 2 XRP) applies. You can prepare more economical transactions by setting a lower `maxFeeXRP`, or support high-priority transactions by setting a higher `maxFeeXRP` in the RippleAPI constructor.
+ When using `sign` with a Fee higher than `maxFeeXRP`, a `ValidationError` is thrown.

```

## 1.0.0-beta.1 (2018-05-24)

### Breaking Changes

+ Amounts in drops and XRP are checked for validity. Some
  methods may now throw a `BigNumber Error` or `ValidationError` if the amount
  is invalid. This may include methods that previously did not throw.
+ Note that 1 drop is equivalent to 0.000001 XRP and 1 XRP is equivalent to 1,000,000 drops.
+ Using drops is recommended. All rippled APIs require XRP amounts to be
  expressed in drops.

### Other Changes

+ Allow specifying amounts in drops for consistency with the `rippled`
  APIs.
+ Export `xrpToDrops()` and `dropsToXrp()` functions.
+ Potentially breaking change: Improve errors. For example, `RippledError` now includes the full response from
  the `rippled` server ([#687](https://github.com/ripple/ripple-lib/issues/687)). `NotConnectedError`
  may be thrown with a different message than before.

+ [Add `request`, `hasNextPage`, and
  `requestNextPage`](https://github.com/ripple/ripple-lib/pull/887).
  + This provides support for all rippled APIs, including subscriptions.

When using rippled APIs, you must:
+ For all XRP amounts, use drops (1 drop = 0.000001 XRP).
+ Instead of `counterparty`, use `issuer`.

The check is a promise from the source of the check that the destination of the check may cash the check and receive up to the SendMax specified on the check. The check may have an (optional) expiration, after which the check may no longer be cashed.
  + **CheckCancel** removes the check from the ledger without transferring funds. Either the check's source or destination can cancel the check at any time. After a check has expired, any account can cancel the check.
  + **CheckCash** is a request by the destination of the check to transfer a requested amount of funds, up to the check's SendMax, from the source to the destination. The destination may receive less than the SendMax due to transfer fees.
+ [Add support for the Deposit Authorization account root flag](https://github.com/ripple/ripple-lib/pull/852)
+ [Generate .ts.d TypeScript declaration files](https://github.com/ripple/ripple-lib/pull/851)

## 0.10.0

+ [Transaction changes](https://github.com/ripple/ripple-lib/pull/221)
+ **Important** `tef*` and `tel*` and errors will no longer be presented as
final. Rather than considering these errors final, ripple-lib will wait until
the `LastLedgerSequence` specified in the transaction is exceeded.  This makes
failures more definitive, and ensures that no transaction will resubmit
indefinitely.
+ A new, final tej-class error is introduced to account for transactions that
are locally determined to have expired: `tejMaxLedger`.
+ [Allow per transaction fees to be set, `transaction.setFixedFee()`](https://github.com/ripple/ripple-lib/commit/9b22f279bcbe60ee6bcf4b7fa60a48e9c197a828)
+ [Improve memo support](https://github.com/ripple/ripple-lib/commit/1704ac4ae144c0ce54afad86f644c75a632080b1)
    - Add `MemoFormat` property for memo
    - Enforce `MemoFormat` and `MemoType` to be valid ASCII
    - Support `text` and `json` MemoFormat
+ [Update sjcl library](https://github.com/ripple/ripple-lib/commit/3204998fcb6f31d6c90532a737a4adb8a1e420f6)
    - Improved entropy by taking advantage of platform crypto
    - Use jscl's k256 curve instead of altering the c256 curve with k256 configuration
    - **Deprecated:** The c256 curve is linked to the k256 curve to provide backwards compatibility, this link will be removed in the future
+ [Fix empty queue check on reconnect](https://github.com/ripple/ripple-lib/commit/3c21994adcf72d1fbd87d453ceb917f9ad6df4ec)

## 0.9.2

__BREAKING CHANGES__
+ [Change accountRequest method signature](https://github.com/ripple/ripple-lib/commit/6f5d1104aa3eb440c518ec4f39e264fdce15fa15)

__OTHER CHANGES__
+ [Add paging behavior for account requests, `account_lines` and `account_offers`](https://github.com/ripple/ripple-lib/commit/722f4e175dbbf378e51b49142d0285f87acb22d7)
+ [Add max_fee setter to transactions to set max fee the submitter is willing to pay](https://github.com/ripple/ripple-lib/commit/24587fab9c8ad3840d7aa345a7037b48839e09d7)
+ [Fix: cap IOU Amounts to their max and min value](https://github.com/ripple/ripple-lib/commit/f05941fbc46fdb7c6fe7ad72927af02d527ffeed)

Example on how to use paging with `account_offers`:
```js
// A valid `ledger_index` or `ledger_hash` is required to provide a reliable result.
// Results can change between ledger closes, so the provided ledger will be used as base.
var options = {
    account: < rippleAccount >,
    limit: < Number between 10 and 400 >,
    ledger: < valid ledger_index or ledger_hash >
}

// The `marker` comes back in an account request if there are more results than are returned
// in the current response. The amount of results per response are determined by the `limit`.
if (marker) {
    options.marker = < marker >;
}

var request = remote.requestAccountOffers(options);
```

+ Make npm test runnable in Windows.
+ Fix several stability issues, see merged PR's for details
+ Fix bug in Amount.to_human_full()
+ Fix undefined fee states when connecting to a rippled that is syncing

## 0.8.0

+ Orderbook: Added tracking of offer funds for determining when offers are not funded
+ Orderbook: Added tests
+ Orderbook: Update owner funds
+ Transactions: If transaction errs with `tefALREADY`, wait until all possible submissions err with the same before emitting `error`. Fixes a client "Transaction malformed" bug.

## 0.7.39

+ Improvements to multi-server support. Fixed an issue where a server's score was not reset and connections would keep dropping after being connected for a significant amount of time.
+ Improvements in order book support. Added support for currency pairs with interest bearing currencies. You can request an order book with hex, ISO code or full name for the currency.
+ Fix value parsing for amount/currency order pairs, e.g. `Amount.from_human("XAU 12345.6789")`
+ Improved Amount parsing from human readable string given a hex currency, e.g. `Amount.from_human("10 015841551A748AD2C1F76FF6ECB0CCCD00000000")`
+ Improvements to username normalization in the vault client
+ Add 2-factor authentication support for vault client
+ Removed vestiges of Grunt, switched to Gulp

## 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.
    ```js
      {
        binary: true,
        parseBinary: false
      }
    ```
+ Added full currency name support, e.g. `Currency.from_json('XRP').to_human({full_name:'Ripples'})` will return `XRP - Ripples`
+ Improved interest bearing currency support, e.g. `Currency.from_human('USD - US Dollar (2.5%pa)')`
+ 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](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 inadequate. 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.

```js
  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.
