Sorry for the frustration. In addition to what Italo has said, we have a seperate article for release notes wherein you can find the list of all new features: https://helpx.adobe.com/in/xd/release-notes.html for any release.
We will also share your feedback with the team to share more specification. Hope it helps.
Hi, the notes you read in this type of updates, as you can read, are to indicate that improvements have been made to the software. If, on the other hand, you intend to read more full-bodied notes, such as adding new features, I recommend reading the Adobe XD blog. You will find many articles, constantly updated, on updates and software majors.
