v1.5

• Added ESP32 compatibility.
• Added the possibility of using the MQTT client without handling the WiFi connection (#9).
• Wiser memory management for WiFiClient and PubSubClient instanciation.

v1.4.1

Fix an initialization issue with serial debugging (bug from v1.4)

v1.4

• Memory optimisation: remove the use of an additionnal buffer in mqttMessageReceivedCallback
• Add support for MQTT last will message.
• Add support for MQTT persistence (cleanSession = false)
• Constructor modification :
  • onConnectionEstablished explicit argument has been removed, the callback will alway be named onConnectionEstablished and you MUST implement it in your sketch.
  • enableSerialLogs has been removed, now you need to call enableDebuggingMessages if you want to enable them.
  • enableWebUpdater has been removed, now you need to call enableHTTPWebUpdater if you want to enable it.
  • MQTT port default to 1883, can be changed from constructor

Upgrading to new constructor format is recommended but the old one still work.

v1.3

• Subscribe function is corrected to avoid "multiple" handlers (thanks to @grafspirt)
• New constructor formulation that allow to pass few arguments (thanks to @grafspirt)
  • Upgrading your code to match the new constructor form is recommended, but the old one still work.
• Serial messages are normalized (thanks to @grafspirt)
• Documentation changes
• Code formating changes
• Corrected the example folder name

v1.2

• Added the possibility to unsubscibe (thanks to @MatasJu)
• Many improvement and optimisations.
  • Removed uses of std::function
  • Indentation fixes
  • Use #define instead of static const class members
  • String type was used too much while it was not necessary. Replaced most of them with uses of char arrays
  • Renamed some variables for better code reading
  • Better MQTT serial logs
  • Better wifi connection attempts handling, should solve the issue encontered by PiterKh (#2)
  • Better handling of received messages in mqttMessageReceivedCallback
  • Added comments to the exemple sketch

v1.1

Renamed Esp8266MQTTClient to EspMQTTClient

v1.0
