Esp8266 RTOS SDK Version?


I’m developing software for AVR and now I want to switch to ESP8266 (RTOS SDK). For some time I’m looking for information about RTOS SDK version used in PlatformIO. Is it 1., 2. or 3.0?? I can’t find good information about this. Do you could give me some reliable information about this??

P.S. for me PlatformIO with VSCode is super stuff for developing AVR. Very good job!!

Best Regards
