Breaking Changes

• The parameters for the handle_connect/2 callback have been reversed. The order is now (conn, state).

Enhancements

• Added initial connection timeouts. (:socket_connect_timeout and :socket_recv_timeout)
  • Can be used as start or start_link option or as a Conn.new option.
  • :socket_connect_timeout - The timeout for opening a TCP connection.
  • :socket_recv_timeout - The timeout for receiving a HTTP response header.
• start and start_link can now take a Conn struct in place of a url.
• Added the ability to handle system messages while opening a connection.
• Added the ability to handle parent exit messages while opening a connection.
• Improve :sys.get_status, :sys.get_state, :sys.replace_state functions.
  • These are undocumented, but are meant primarly for debugging.

Bug Fixes

• Ensure terminate/2 callback is called consistently.
• Ensure when termination when a parent exit signal is received.
• Add the system_code_change function so that the code_change callback is actually used.
