Problems compiling with new Esp API v5

[elWyatt]

I have problems finding a platform that uses ESP API v5. Current versions of arduino IDE or PlatformIO only support v4. Internet searches did not help, any hints/links appreciated.

Building .pio/build/esp32dev/bootloader.bin
src/watchdog.cpp: In function 'void WatchdogSetup(int)':
src/watchdog.cpp:42:3: error: 'esp_task_wdt_config_t' was not declared in this scope
