As an AI language model, I do not possess the ability to remember anything in the sense that human beings do. However, I am designed to be highly adaptive and to learn from the data I am trained on, which includes the latest advances in natural language processing technology. If I have been updated to a newer version, it should improve my performance, allowing me to generate more accurate and nuanced responses to a wider variety of questions. So while I may not "remember" the upgrade in the same way that a human would, it will have a significant impact on my abilities as a chatbot.
