Where can I see what changed in each Storage Studio update?
Short answer: See the release notes page on the Storage Studio website, or click Release notes on the Updates card in Settings → License. New features also appear in the Learning Center.
Every version's changes are listed on the release notes page. You can also reach them from the app: when an update is available, the Updates card in Settings → License has a Release notes button next to Download.
New features are also highlighted in the Learning Center (the book icon at the top of the window), which turns yellow with a small dot when there's something you haven't seen.
