v0.8.0: SSL/TLS and stability

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.).

✨ 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

🐛 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

📝 Docs

• Provide information about the memory usage

v0.7.1: Fix for QoS 0

🐛 Bugfixes

• A successful publish was always returning 0. Now, it returns a dummy 1 to differentiate from the 0 of a failed sending

v0.7.0: yet more stability

✨ Enhancements

• Return 0 from publish, subscribe and unsubscribe if there's not enough TCP space to send the packet

🐛 Bugfixes

• Fix Keep Alive
• Fix cases where a reconnection takes two times before actually reconnecting
• Fix the example to automatically reconnect to Wi-Fi
