+### 0.7.4 / 2020-05-22
+
+- Avoid crashing if `process.version` does not contain any digits
+- Emit `ping` and `pong` events from the `Server` driver
+- Require http-parser-js >=0.5.1 which fixes the bug we addressed in 0.7.3
+
+### 0.7.3 / 2019-06-13
+
+- Cap version of http-parser-js below 0.4.11, which introduced a bug that

+  the handshake response if chunked encoding is specified
+
+### 0.7.2 / 2019-06-13
+
+(This version was pulled due to an error when publishing)
+
+### 0.7.1 / 2019-06-10
+
+- Catch any exceptions produced while generating a handshake response and send a
+  `400 Bad Request` response to the client
+- Pick the RFC-6455 protocol version if the request contains any of the headers
+  used by that version
+- Use the `Buffer.alloc()` and `Buffer.from()` functions instead of the unsafe
+  `Buffer()` constructor
+- Handle errors encountered while handling malformed draft-76 requests
+- Change license from MIT to Apache 2.0
+
+### 0.7.0 / 2017-09-11
+
+- Add `ping` and `pong` to the set of events users can listen to
+- Replace the bindings to Node's HTTP parser with `http-parser-js`
+
+### 0.6.5 / 2016-05-20
+
+- Don't mutate buffers passed in by the application when masking
+
+### 0.6.4 / 2016-01-07
+
+- If a number is given as input for a frame payload, send it as a string
+
+### 0.6.3 / 2015-11-06
+
+- Reject draft-76 handshakes if their Sec-WebSocket-Key headers are invalid
+- Throw a more helpful error if a client is created with an invalid URL
+
+### 0.6.2 / 2015-07-18
+
+- When the peer sends a close frame with no error code, emit 1000
+
+### 0.6.1 / 2015-07-13
+
+- Use the `buffer.{read,write}UInt{16,32}BE` methods for reading/writing numbers
+  to buffers rather than including duplicate logic for this
+
+### 0.6.0 / 2015-07-08
+
+- Allow the parser to recover cleanly if event listeners raise an error
+- Add a `pong` method for sending unsolicited pong frames
+
+### 0.5.4 / 2015-03-29
+
+- Don't emit extra close frames if we receive a close frame after we already
+  sent one
+- Fail the connection when the driver receives an invalid
+  `Sec-WebSocket-Extensions` header
+
+### 0.5.3 / 2015-02-22

+- Don't treat incoming data as WebSocket frames if a client driver is closed
+  before receiving the server handshake

+
+- Don't allow drivers to be created with unrecognized options

+- It is now possible to call `close()` before `start()` and close the driver
+
+### 0.3.5 / 2014-07-06
+
+- Don't hold references to frame buffers after a message has been emitted
+- Make sure that `protocol` and `version` are exposed properly by the TCP driver
