Soon. One of the big changes of 2.1.9 is for OS 2.3 to transition to use UIPEthernet library so that it can support similar functionalities already in place in OS 3.0, and also using UIPEthernet makes it easy to integrate cloud features through Blynk. The other big change is to move controller settings and program settings all to SD card, so that expand the number of parameters and programs without blowing out the EEPROM on OS 2.3. I’ve got most of library transition part done, but it still needs quite a bit of testing and debugging.
