3.14.10013498 Oct 1
Features
Operational Flight Plan (OFP) Integration
Guru2 now has the ability to import and display OFP data. View NOTAM and weather data documents directly in Guru2. Enter in-flight route point data (ETO, RET, ATO, and ACT), which can then be exported to BackOffice.
Please reach out to support to enabled this feature
Automatically Set Cursor at the End of Input
When entering or focusing an input field, the cursor is now automatically moved to the right of the last entered character, making it easier to erase values.
Improvements
Tail Configuration: Save and Apply Configuration Diff
Guru2 will now always use the base tail configuration. When importing a configuration from BackOffice, those settings will now be applied on top of the base configuration.
Clarified Update Tab Information
On the Update tab, the information shown when no tails are subscribed in BackOffice has been clarified.
New Deep Link API Identifier
Added a new unique identifier to the Deep Link API for exporting calculation results back to the integrator. This will be used in EFBOne deep links.
Require EFBOne account, please reach out to support to enabled this feature
Manual Updates
Added information about Balked Landing and "Use Dispatch Input" to the manual.
Bug Fixes
Prevented Flights with Overlong Flight Numbers

Fixed an issue that could occur when exiting a flight directly after creating an alternate.
Fixed an issue where dispatch runway information was unavailable when exceeding limits.
Fixed an issue that prevented NOTAMs from being created while offline on Windows.

3.14.00013498 Sep 29
Version 3.13.0 of Guru2 is now available! This release brings improvements, new updates, and features aimed at enhancing performance and stability.
Features
Nearest TAF
The nearest weather feature can now also retrieve the nearest TAF. If no TAF is available for the selected ICAO, the system will automatically attempt to fetch the closest available TAF instead.
This feature is disabled by default and can be enabled through configuration by our support team. If you would like to enable it, please contact support for assistance.
Auto Select Flight
When using multiple resource-intensive apps on iOS and switching between them, iOS may occasionally close Guru2 in the background. When returning to the app, users could end up on the start screen and would need to manually reselect the flight they were working on.
With this update, Guru2 will automatically reopen the last visited flight and restore the last active tab within that flight. If the app was closed while outside a flight, it will instead open on the Updates tab.
Auto Fill Inflight Using Dispatch Values
A new “Use Dispatch Input” button has been added to the inflight input tab. When selected, the inflight inputs are automatically populated using the corresponding values from dispatch.
Runway conditions are not transferred, as they may differ between dispatch and inflight operations.
Improvements
Display Title Bar When Not in Fullscreen (Windows)
The title bar is now displayed when the application is running in windowed mode. The application will still launch in fullscreen by default, as it is primarily designed for tablet use.
Extra NOTAM Improvements
Added hours and minutes to NOTAM start and end dates. Improved the tooltip displayed when entering an existing NOTAM ID.
Improved Display of Long Configuration Labels
Long configuration item labels on the takeoff, dispatch, and inflight input views have been adjusted to display better on smaller tablets, ensuring improved readability and layout consistency.
Added TASS Example to Manual
Added an explanation of TASS in section 5.3 of the Datacard manual, including how switching between OAT and TASS affects functionality.
The update also clarifies that these controls are interactive and includes an example demonstrating TASS usage.
Bug Fixes
Fixed an issue where a flight could neither be exported nor deleted.
Fixed unintended app size growth in some cases
If the installed app size has become unusually large, please reinstall the application to remove old data.
Make sure to export all flights before reinstalling.
Integration: The to_percent_mac value is now imported even when to_weight is not set.
Fixed numeric keyboard not automatically appearing for numeric input fields.
Several fixes related to Extra NOTAM.
