Release Notes.

The old book is about to be finished, and the new book also needs to be conceived for review by the website. I stayed up until about three o'clock in the morning last night, working on the structure. I wanted to sleep for a while and write a chapter in the morning, but I couldn't fall asleep. I was in poor condition, so I postponed the early update. I owe you one for two, and I will update 4 chapters in the evening.
