2.4.0 Long waiting on develop :)

New features:

• Additional architectures: ESP8266, ESP32 (experimental)
• Ethernet (LAN or MQTT) with W5100 or ENC28J60
• Add multiple hardware combinations to platformio.ini so the user doesn't need to customize it so often
• add EEPROM_OFFSET option

Improvements:

• Change button logic to be more independent from relays
• Create wrapper for MySensors dependency so it can be better tested

2.3.2 Minor fixes to stable version

• improve Virtual pins
• typos fixes and revert remove "xstr" macro
• add timestamp to default serial monitor output

2.3.1 Fixes and cleanup after release 2.3.0

• cleanup - remove some commented code
• add some inline directive
• increase relay and button description to 30 characters
• updated documentation (especially PROGMEM directive)
• fixed expander compilation errors
• added expander support in Configuration class
• added unit tests for Configuration class
• added compilation option in platformio.ini to increase serial buffer when having communication problems (SERIAL_RX_BUFFER_SIZE)

2.3.0 - Big architecture refactoring and new functionality - dependent relays

New functionality:

• Dependent relays and new configuration option "dependsOn"

Technical changes:

• Completely new software architecture to separate responsibility and add hardware abstraction for unit testing:
  • New class ButtonService
  • New class RelayService
  • New class Switch (hardware layer for buttons)
  • Separate class for every button type
  • Arduino abstraction layer - Arduino specific items located in ArduinoAbstract.h/cpp files
    • Common Pins interface including expander implementation
  • new class Eeprom - EEPROM abstraction for testing
  • new class Configuration
• Unit testing in native mode (on local PC) - thanks to Arduino abstraction/mock most code can be unit tested
• Ability to validate configuration in native mode
• Removed Bounce2 library
• Configuration and all strings moved to flash memory - free SRAM memory
• Removed all usages of String class (less memory consumption)
• All serial output using C++ streams ("Serial << …")
• A lot of dynamic memory allocation, but mostly only at startup
• Unfortunately, the above comes at a cost with a lot of dynamic memory allocation, but mostly only during boot and never freed up

Sensor reporting

• reporting REED_SWITCH as S_DOOR in MySensors

Stable release
