++ [**Breaking change**: Change accountRequest method signature](https://github.com/ripple/ripple-lib/commit/6f5d1104aa3eb440c518ec4f39e264fdce15fa15)
+
++ [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`:
+```
+// 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);
+```
+
+[Full working example](https://github.com/geertweening/ripple-lib-scripts/blob/master/account_offers_paging.js)
+
+
+##0.9.1

+
++ Currency: add `show_interest` flag to show or hide interest in `Currency.to_human()` and `Currency.to_json()` [Example use in tests](https://github.com/ripple/ripple-lib/blob/947ec3edc2e7c8f1ef097e496bf552c74366e749/test/currency-test.js#L123)
+
++ Configurable maxAttempts for transaction submission ([d107092](https://github.com/ripple/ripple-lib/commit/d10709254061e9e4416d2cb78b5cac1ec0d7ffa5))

+
+
+##0.8.2
+
++ Currency: Allow mixed letters and numbers in currencies
+
++ Deprecate account_tx map/reduce/filterg
+
++ Fix: correct requestLedger arguments
+
++ Fix: missing subscription on error events for some server methods
+
++ Fix: orderbook reset on reconnect
+
++ Fix: ripple-lib crashing. Add potential missing error handlers
+
+
+##0.8.1
+
++ Wallet: Add Wallet class that generates wallets
+
++ 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.
+
++ Transactions: Track submissions, don't bother submitting to unconnected servers
+
++ Request: `request.request()` now accepts an array of servers as first argument. Servers can be represented with URL, or the server object itself.
+
++ Request: `request.broadcast()` now returns the number of servers request was sent to
+
++ Server: Acquire host information from server without additional request
+
++ Amount: Add a constant for the maximum canonical value that can be expressed as a Ripple value
+
++ Amount: Make Constants static fields on the class, instead of a seperate export
+
+
+##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 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.
+
+```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)
+```
+

-##Initializing a remote connection
+[![NPM](https://nodei.co/npm/ripple-lib.png)](https://www.npmjs.org/package/ripple-lib)
 
-[ripple-lib.remote](https://github.com/ripple/ripple-lib/blob/develop/src/js/ripple/remote.js) is responsible for managing connections to rippled servers.
+###Features
+
++ Connect to a rippled server in JavaScript (Node.js or browser)
++ Issue [rippled API](https://ripple.com/wiki/JSON_Messages) requests
++ Listen to events on the Ripple network (transaction, ledger, etc.)
++ Sign and submit transactions to the Ripple network

+
+##Installation
+
+**Via npm for Node.js**
+
+```
+  $ npm install ripple-lib
+```
+
+**Via bower (for browser use)**
+
+```
+  $ bower install ripple
+```
+
+See the [bower-ripple repo](https://github.com/ripple/bower-ripple) for additional bower instructions
+
+
+**Building ripple-lib from github**
+
+```
+  $ git clone https://github.com/ripple/ripple-lib
+  $ npm install
+  $ npm run build
+```
+
+Then use the minified `build/ripple-*-min.js`
+
+##Quickstart
+
+`Remote.js` ([remote.js](https://github.com/ripple/ripple-lib/blob/develop/src/js/ripple/remote.js)) is the point of entry for interacting with rippled
 
 ```js
+/* Loading ripple-lib with Node.js */
 var Remote = require('ripple-lib').Remote;
 
+/* Loading ripple-lib in a webpage */
+// var Remote = ripple.Remote;
+
 var remote = new Remote({
-  trusted: false,
-  servers: [ 
-    { 
-        host: ''
-      , port: 1111,
-      , secure: true
-    } 
-  ]
+  // see the API Reference for available options
+  servers: [ 'wss://s1.ripple.com:443' ]
 });
 
-remote.connect();
-```
-
-Once a connection is formed to any of the supplied servers, a `connect` event is emitted, indicating that the remote is ready to begin fulfilling requests. When there are no more connected servers to fulfill requests, a `disconnect` event is emitted. If you send requests before ripple-lib is connected to any servers, requests are deferred until the `connect` event is received.
-
-```js
-var remote = new Remote({ /* options */ }).connect();
-remote.request_server_info(function(err, info) { }); // will defer until connected
-```
-
-##Remote functions
-
-Each remote function returns a `Request` object. is object is an `EventEmitter`. You may listen for success or failure events from each request, or provide a callback. Example:
-
-```js
-var request = remote.request_server_info();
-request.on('success', function(res) { 
-  //handle success conditions
-});
-request.on('error', function(err) { 
-  //handle error conditions
-});
-request.request();
-```
-
-Or:
-
-```js
-remote.request_server_info(function(err, res) {
-  
+remote.connect(function() {
+  /* remote connected */
+  remote.requestServerInfo(function(err, info) {
+    // process err and info
+  });
 });
 ```

+3. Create a new `Remote` and connect to the network:
+  ```js
+
+  var options = {
+    trace :         false,
+    trusted:        true,
+    local_signing:  true,
+    servers: [
+      { host: 's-west.ripple.com', port: 443, secure: true }
+    ]
+  }
+
+  var remote = new Remote({options});
+
+  remote.connect(function(err, res) {
+    /* remote connected, use some remote functions here */
+  });
+  ```
+  __NOTE:__ See the API Reference for available [`Remote` options](REFERENCE.md#1-remote-options)
+
+4. You're connected! Read on to see what to do now.
+
+
+##Sending rippled API requests
+
+`Remote` contains functions for constructing a `Request` object. 
+
+A `Request` is an `EventEmitter` so you can listen for success or failure events -- or, instead, you can provide a callback.
+
+Here is an example, using [requestServerInfo](https://ripple.com/wiki/JSON_Messages#server_info).
+
++ Constructing a `Request` with event listeners
+```js
+var request = remote.requestServerInfo();
+
+request.on('success', function onSuccess(res) {
+  //handle success
+});
+
+request.on('error', function onError(err) {
+  //handle error
+});
+
+request.request();
+```
+
++ Using a callback:
+```js
+remote.request('server_info', function(err, res) {
+  if (err) {
+    //handle error
+  } else {
+    //handle success
+  }
+});
+```
+
+__NOTE:__ See the API Reference for available [`Remote` functions](REFERENCE.md#2-remote-functions)
+
+
+##Listening to the network
+
+See the [wiki](https://ripple.com/wiki/JSON_Messages#subscribe) for details on subscription requests.
+
+```js
+ /* Loading ripple-lib with Node.js */
+  var Remote = require('ripple-lib').Remote;
+
+  /* Loading ripple-lib in a webpage */
+  // var Remote = ripple.Remote;
+
+  var remote = new Remote({options});
+
+  remote.connect(function() {
+    var remote = new Remote({
+      // see the API Reference for available options
+      servers: [ 'wss://s1.ripple.com:443' ]
+    });
+
+    remote.connect(function() {
+      console.log('Remote connected');
+
+      var streams = [
+        'ledger',
+        'transactions'
+      ];
+    
+      var request = remote.requestSubscribe(streams);
+    
+      request.on('error', function(error) {
+        console.log('request error: ', error);
+      });
+    
+    
+      // the `ledger_closed` and `transaction` will come in on the remote
+      // since the request for subscribe is finalized after the success return
+      // the streaming events will still come in, but not on the initial request
+      remote.on('ledger_closed', function(ledger) {
+        console.log('ledger_closed: ', JSON.stringify(ledger, null, 2));
+      });
+    
+      remote.on('transaction', function(transaction) {
+        console.log('transaction: ', JSON.stringify(transaction, null, 2));
+      });
+    
+      remote.on('error', function(error) {
+        console.log('remote error: ', error);
+      });
+    
+      // fire the request
+      request.request();
+    });
+  });

+##Submitting a payment to the network
+
+Submitting a payment transaction to the Ripple network involves connecting to a `Remote`, creating a transaction, signing it with the user's secret, and submitting it to the `rippled` server. Note that the `Amount` module is used to convert human-readable amounts like '1XRP' or '10.50USD' to the type of Amount object used by the Ripple network.
+
+```js
+/* Loading ripple-lib Remote and Amount modules in Node.js */ 
+var Remote = require('ripple-lib').Remote;
+var Amount = require('ripple-lib').Amount;
+
+/* Loading ripple-lib Remote and Amount modules in a webpage */
+// var Remote = ripple.Remote;
+// var Amount = ripple.Amount;
+
+var MY_ADDRESS = 'rrrMyAddress';
+var MY_SECRET  = 'secret';
+var RECIPIENT  = 'rrrRecipient';
+var AMOUNT     = Amount.from_human('1XRP');
+
+var remote = new Remote({ /* Remote options */ });
+
+remote.connect(function() {
+  remote.setSecret(MY_ADDRESS, MY_SECRET);
+
+  var transaction = remote.createTransaction('Payment', {
+    account: MY_ADDRESS, 
+    destination: RECIPIENT, 
+    amount: AMOUNT
+  });
+
+  transaction.submit(function(err, res) {
+    /* handle submission errors / success */
+  });
+});
+```
+
+###A note on transaction fees
+
+A full description of network transaction fees can be found on the [Ripple Wiki](https://ripple.com/wiki/Transaction_Fee).
+
+In short, transaction fees are very small amounts (on the order of ~10) of [XRP drops](https://ripple.com/wiki/Ripple_credits#Notes_on_drops) spent and destroyed with every transaction. They are largely used to account for network load and prevent spam. With `ripple-lib`, transaction fees are calculated locally by default and the fee you are willing to pay is submitted along with your transaction.
+
+Since the fee required for a transaction may change between the time when the original fee was calculated and the time when the transaction is submitted, it is wise to use the [`fee_cushion`](REFERENCE.md#1-remote-options) to ensure that the transaction will go through. For example, suppose the original fee calculated for a transaction was 10 XRP drops but at the instant the transaction is submitted the server is experiencing a higher load and it has raised its minimum fee to 12 XRP drops. Without a `fee_cusion`, this transaction would not be processed by the server, but with a `fee_cusion` of, say, 1.5 it would be processed and you would just pay the 2 extra XRP drops.
+
+The [`max_fee`](REFERENCE.md#1-remote-options) option can be used to avoid submitting a transaction to a server that is charging unreasonably high fees.
+
+
+##4. Submitting a trade offer to the network
+
+Submitting a trade offer to the network is similar to submitting a payment transaction. Here is an example for a trade that expires in 24 hours where you are offering to sell 1 USD in exchange for 100 XRP:
+
+```js
+/* Loading ripple-lib Remote and Amount modules in Node.js */ 
+var Remote = require('ripple-lib').Remote;
+var Amount = require('ripple-lib').Amount;
+
+/* Loading ripple-lib Remote and Amount modules in a webpage */
+// var Remote = ripple.Remote;
+// var Amount = ripple.Amount;
+
+var MY_ADDRESS = 'rrrMyAddress';
+var MY_SECRET  = 'secret';
+var GATEWAY = 'rrrGateWay';
+
+var remote = new Remote({ /* Remote options */ });
+
+remote.connect(function() {
+  remote.setSecret(MY_ADDRESS, MY_SECRET);
+
+  var transaction = remote.createTransaction('OfferCreate', {
+    account: MY_ADDRESS,
+    taker_pays: '1',
+    taker_gets: '1/USD/' + GATEWAY
+  });
+
+  transaction.submit(function(err, res) {
+    /* handle submission errors / success */
+  });
+});
+```

+
+#Request constructor functions
+
+Some requests have helper methods to construct the requests object and set properties on the message object. These will often be the more used requests and the helper methods is the preferred way of constructing these requests.
+Other request can still be made, but the type will have to be passed in directly to request constructor. See examples below.
+
+If the method is camelCased and starts with `request`, it's a helper method that wraps the request constructor.

+##Transaction events
+
+[Transaction](https://github.com/ripple/ripple-lib/blob/develop/src/js/ripple/transaction.js) objects are EventEmitters. They may emit the following events.
+
++ `final` Transaction has erred or succeeded. This event indicates that the transaction has finished processing.
++ `error` Transaction has erred. This event is a final state.
++ `success` Transaction succeeded. This event is a final state.
++ `presubmit` Immediately before transaction is submitted
++ `postsubmit` Immediately after transaction is submitted
++ `submitted` Transaction has been submitted to the network. The submission may result in a remote error or success.
++ `resubmitted` Transaction is beginning resubmission.
++ `proposed` Transaction has been submitted *successfully* to the network. The transaction at this point is awaiting validation in a ledger.
++ `timeout` Transaction submission timed out. The transaction will be resubmitted.
++ `fee_adjusted` Transaction fee has been adjusted during its pending state. The transaction fee will only be adjusted if the remote is configured for local fees, which it is by default.
++ `abort` Transaction has been aborted. Transactions are only aborted by manual calls to `#abort`.
++ `missing` Four ledgers have closed without detecting validated transaction
++ `lost` Eight ledgers have closed without detecting validated transaction. Consider the transaction lost and err/finalize.
+
+##Complete payment example

+var transaction = remote.createTransaction('Payment', {
+  account: MY_ADDRESS,
+  destination: DEST_ADDRESS,
+  amount: AMOUNT
+});
+
+transaction.on('resubmitted', function() {
+  // initial submission failed, resubmitting
+});
+
+transaction.submit(function(err, res) {
+ // submission has finalized with either an error or success.
+ // the transaction will not be retried after this point
