 # ripple-lib Release History
 
+## 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)
+
+The SHA-256 checksums for the browser version of this release can be found
+below.

+
+## 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.
+
+If you have any questions or concerns, please open an issue on GitHub.

+
+## 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.

XRP has a maximum value of `100000000000` (1e11). Some RippleAPI methods accept XRP in order to maintain compatibility with older versions of the API. For consistency with the `rippled` APIs, we recommend formally specifying XRP values in *drops* in all API requests, and converting them to XRP for display.

 **Non-XRP values** have 16 decimal digits of precision, with a maximum value of `9999999999999999e80`. The smallest positive non-XRP value is `1e-81`.

+# rippled APIs
+
+ripple-lib relies on [rippled APIs](https://ripple.com/build/rippled-apis/) for all online functionality. With ripple-lib version 1.0.0 and higher, you can easily access rippled APIs through ripple-lib. Use the `request()`, `hasNextPage()`, and `requestNextPage()` methods:
+* Use `request()` to issue any `rippled` command, including `account_currencies`, `subscribe`, and `unsubscribe`. [Full list of API Methods](https://ripple.com/build/rippled-apis/#api-methods). 
+* Use `hasNextPage()` to determine whether a response has more pages. This is true when the response includes a [`marker` field](https://ripple.com/build/rippled-apis/#markers-and-pagination).
+* Use `requestNextPage()` to request the next page of data.
+
+When using rippled APIs, [specify XRP amounts in drops](https://ripple.com/build/rippled-apis/#specifying-currency-amounts). 1 XRP = 1000000 drops.
+
+## Listening to streams
+
+The `rippled` server can push updates to your client when various events happen. Refer to [Subscriptions in the `rippled` API docs](https://ripple.com/build/rippled-apis/#subscriptions) for details.
+
+Note that the `streams` parameter for generic streams takes an array. For example, to subscribe to the `validations` stream, use `{ streams: [ 'validations' ] }`.
+
+The string names of some generic streams to subscribe to are in the table below. (Refer to `rippled` for an up-to-date list of streams.)
+
+Type | Description
+---- | -----------
+`server` | Sends a message whenever the status of the `rippled` server (for example, network connectivity) changes.
+`ledger` | Sends a message whenever the consensus process declares a new validated ledger.
+`transactions` | Sends a message whenever a transaction is included in a closed ledger.
+`transactions_proposed` | Sends a message whenever a transaction is included in a closed ledger, as well as some transactions that have not yet been included in a validated ledger and may never be. Not all proposed transactions appear before validation. Even some transactions that don't succeed are included in validated ledgers because they take the anti-spam transaction fee.
+`validations` | Sends a message whenever the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
+`manifests` | Sends a message whenever the server receives a manifest.
+`peer_status` | (Admin-only) Information about connected peer `rippled` servers, especially with regards to the consensus process.
+
+When you subscribe to a stream, you must also listen to the relevant message type(s). Some of the available message types are in the table below. (Refer to `rippled` for an up-to-date list of message types.)
+
+Type | Description
+---- | -----------
+`ledgerClosed` | Sent by the `ledger` stream when the consensus process declares a new fully validated ledger. The message identifies the ledger and provides some information about its contents.
+`validationReceived` | Sent by the `validations` stream when the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
+`manifestReceived` | Sent by the `manifests` stream when the server receives a manifest.
+`transaction` | Sent by many subscriptions including `transactions`, `transactions_proposed`, `accounts`, `accounts_proposed`, and `book` (Order Book). See [Transaction Streams](https://ripple.com/build/rippled-apis/#transaction-streams) for details.
+`peerStatusChange` | (Admin-only) Reports a large amount of information on the activities of other `rippled` servers to which the server is connected.
+
+To register your listener function, use `connection.on(type, handler)`.
+
+Here is an example of listening for transactions on given account(s):
+```
+const account = 'rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn' // Replace with the account you want notifications for
+api.connect().then(() => { // Omit this if you are already connected
+
+  // 'transaction' can be replaced with the relevant `type` from the table above
+  api.connection.on('transaction', (event) => {
+
+      // Do something useful with `event`
+      console.log(JSON.stringify(event, null, 2))
+  })
+
+  api.request('subscribe', {
+      accounts: [ account ]
+  }).then(response => {
+      if (response.status === 'success') {
+          console.log('Successfully subscribed')
+      }
+  }).catch(error => {
+      // Handle `error`
+  })
+})
+```
+
+The subscription ends when you unsubscribe or the WebSocket connection is closed.
+
+For full details, see [rippled Subscriptions](https://ripple.com/build/rippled-apis/#subscriptions).
