This release makes the client more bulletproof than ever. Simply put: right now, even if you do a loop to publish messages at a very fast rate, the client will not break and will not loose functionality (ACKs will still be sent, etc.).

:sparkles: Enhancements

• SSL/TLS support has been added. Note you need the not yet stable esp8266/Arduino 2.4.0 and the -DASYNC_TCP_SSL_ENABLED=1 build flag

:bug: Bugfixes

• Fix packet ID being incremented even if the packet cannot be sent
• Make sure ACKs are sent even if the TCP buffer is full

:memo: Docs

• Provide information about the memory usage
