Did GPT4 Got Retrained?

I noticed that in the “Advanced Data Analysis” mode, the responses to questions with a potential to require up-to-date data are “As my knowledge is cut-off at 1 January 2022”, instead of 2021.

Also, the responses are generally better compared to the default GPT4.

Did I miss the news of one additional year of knowledge added? The effort would make sense though, considering they are now actively trying to attract business customers.
