The "Updates" page tells you what changed and when. Our system continually monitors for changes to aviation-related regulations and the AIM and automatically updates this app with the latest information while preserving your highlighting and bookmarks.
The scrolling text found at the top of the "Home" page tells you when we last found changes to the CFR. The number at the bottom of the page, near the "Updates" button, tells you how many FAR related changes were downloaded since you installed the app or last visited the "Updates" page. If a number is not showing, then there are no updates since you last installed the app or visited the "Updates" page.
The changes listed on the "Updates" page are grouped by date. Tap on a row to see the change details. Items highlighted in the color RED show what was removed, and items highlighted in GREEN show what was added. Tap the button at the top right of the page to navigate to that item.
