 # Changelog
 
 
+## [v3.2.0](https://github.com/Cylix/tacopie/releases/tag/3.2.0)
+### Tag
+`3.2.0`
+### Date
+November 13th, 2017
+### Changes
+* fork support: allow set_default_io_service to take nullptr. In order to safely fork, call set_default_io_service(nullptr) to make sure the io_service destructor is called and all underlying threads joined.
+* fix: timeout for connection not working due to invalid param to select, now working
+* improvement: make sure socket is in blocking mode before connection (#32) as it differs from one OS to another
+* improvement: check for non-blocking connect errors with getsockopt to avoid connect reporting a successful connection followed by a call to disconnection handler (now connect report a failed connection as expected).
+### Additions
+* ipv6 support (connect, bind and accept operations, on tcp_server and tcp_client)
+### Removals
+None
