If both sets of new information are about the same task, one of them will be thrown away. (This is why we want to show you new info as soon as possible, so there's less chance of it getting thrown away.)

If the changes are on different tasks, or different projects, both sets of changes will be kept.

(We're working on making it even smarter about changes, so if you change a task note on one computer and the same task's start date on a different computer, we can keep both changes.)
