What is ""Release mode" in ESP-IDF context

[VinayDand]

Going through documentation for ESP32, in security topic, came across the sentence:

"For production use, flash encryption should be enabled in the "Release" mode only."

I would like to know what is meant by "Release" mode.
Is it meant as oppose to debug mode?
But ESP-IDF does not have separate Release / Debug mode compilation setting
Or I am missing something?

Please help us in understanding the sentence

Best Regards,
Vinay

For flash encryption, you choose between release mode and development mode.
