 # Changelog
 All notable changes to this project will be documented in this file.
 
+## [unreleased] - 2019-06-09
+### Changed
+- mbedtls and zlib are searched with find_package, and we use the vendored version if nothing is found
+- travis CI uses g++ on Linux
+
 ## [4.0.0] - 2019-06-09
 ### Changed
 - WebSocket::send() sends message in TEXT mode by default
 - WebSocketMessage sets a new binary field, which tells whether the received incoming message is binary or text
 - WebSocket::send takes a third arg, binary which default to true (can be text too)
 - WebSocket callback only take one object, a const ix::WebSocketMessagePtr& msg
-- Add explicite WebSocket::sendBinary
+- Add explicit WebSocket::sendBinary method
 - New headers + WebSocketMessage class to hold message data, still not used across the board
 - Add test/compatibility folder with small servers and clients written in different languages and different libraries to test compatibility.
 - ws echo_server has a -g option to print a greeting message on connect
