Well... not really new. But now you need to use it.
Recent upgrades to our Invalid Date checking require the use of the Delete button, on the far right end of a Milestone row to remove a previously saved entry.
To DELETE a saved entry, click the Delete button.
New text on the screen will try to help call attention to the change in function. In the past you might have just taken out the date. After all the logic was "no date" no entry. That will still work, until you save the entry. Then you must use the Delete button. If you persist in trying to just clear the date, you will find the entry still reports on the Timeline view screens.
