Lead with the benefit
Open each item with what the customer can now do, not what the team built. One plain sentence is enough.
Group by what changed for them
Split notes into new, improved and fixed, and put anything that changes how people work at the top.
Warn about changes that need action
If a change needs a customer to do something, say so in its own line with the date. This is the line that prevents tickets.
Link the help article
Link each notable change to the help article that explains it. Update the article before you ship the note.
Brief support before the release
Send the team the notes a day early so they know what to expect and can add a saved reply for the likely question.
Watch the tickets after release
Count tickets that mention the change for a week. A spike means the note or the article missed something.
