Our June Release includes Traffic Breadcrumbs, Day/Night Overlay, Aircraft on Runway Alerts, OneDrive Support for Cloud Documents, and Baro-Corrected Pressure Altitude.
Traffic Breadcrumbs 
Check the flight paths of nearby aircraft to boost your situational awareness and see which runways or procedures are in use while receiving traffic information from an ADS-B or FLARM receiver.
Tap on any airborne or grounded traffic target received via ADS-B or FLARM (not via Internet Traffic) to display its breadcrumb trail in green, along with information about the target, and tap elsewhere on the map to hide it. If enabled, your breadcrumb trail will turn gray while viewing other aircrafts’ breadcrumbs to avoid confusion.
A target’s breadcrumb starts at the first point at which the target appeared in ForeFlight, up to 30 minutes ago, and will disappear if the target disappears from ForeFlight. However, if the same target reappears within two minutes then it will retain its previous breadcrumb trail; more than two minutes, and the trail will restart from scratch.
Traffic Breadcrumbs are enabled by default, but you can disable them using the Traffic Breadcrumbs setting in Map Settings > Map Overlays while connected to an inflight traffic source.
Day/Night Overlay on Maps 
See where night has fallen around the world as well as the real-time day/night boundary directly on the map.
You can enable the new overlay in Map Settings > Day/Night Overlay. On the day side, the map appears normal, while on the night side, it is slightly darkened, with a smooth gradient at the boundary.
Zooming into the map on the night side will cause the shadow to fade and disappear to avoid obscuring map details and interfering with your workflow.
Aircraft on Runway Alerts
Receive critical safety alerts during final approach when an aircraft is present on your runway, as well as when an aircraft is approaching the runway you’re currently on, while connected to an ADS-B or FLARM receiver.
The prominent visual and audio alerts specify which runway the traffic target is occupying and visually highlight the traffic target in red.
These alerts trigger when you’re within either 2 nautical miles or 1 minute from the end of the runway, and ForeFlight detects a traffic target on that runway, and similarly for traffic targets approaching the runway you’re currently on.
You can customize the types of alerts you receive or disable them entirely in Map Settings > Alerts.
Cloud Documents: OneDrive Support
Wirelessly upload custom documents to all your signed-in devices from a connected Microsoft OneDrive folder.
Start by visiting the Documents page on ForeFlight Web, then click Add a Cloud Drive under the My Drives section.
Select OneDrive from the dropdown menu and specify the Drive name as it will appear in ForeFlight and the name of the Drive Folder in OneDrive you want to sync documents from. If you don’t specify a Drive Folder name then ForeFlight will sync all documents and supported files within your OneDrive account.
Baro-Corrected Pressure Altitude
View your corrected barometric altitude based on raw pressure readings and nearby METAR data from internet or FIS-B weather broadcasts on ForeFlight’s Instrument Panel.
To show the Instrument Panel, tap the “steam gauge” icon at the top of ForeFight’s Maps view.
To add Baro Altitude to the panel, tap on any slot to view all available instruments, then select Baro Altitude to view your corrected pressure altitude.
The Cabin Pressure and Pressure Altitude instruments just above it display the uncorrected pressure altitude, and the Nearest Baro instrument further down displays the current baro setting and the identifier of the airport from which it was received.
When baro-corrected pressure altitude is available, the altitude tape in ForeFlight’s attitude indicator (Synthetic Vision) displays this rather than GPS altitude, and indicates the current baro setting at the bottom of the tape.
This instrument will only use barometric pressure data from a reliable source (portable receivers, panel avionics, etc.), not from built-in barometers on iPads or iPhones, unlike the Cabin Pressure instrument which does utilize your device’s built-in barometer.
