Over the next coming days, customers will gradually transition to the updated version. If you encounter any functions that are not working as expected, please notify us via the [Customer Portal](https://customer.leon.aero). ## Admin 1. Added AI Assistant to the Email Templates function. From now on, email templates can be created using AI. More details [here](https://leonsoftware.atlassian.net/wiki/spaces/wiki/pages/3778904073/Added+AI+Assistant+to+the+Email+Templates+function.+From+now+on+email+templates+can+be+created+using+AI.) 2. Added the ability to configure sending MVT messages using local dates. ## Crew 1. Modified the Crew tab in the flight edit view. The summary status dot for a crew member now takes into account the approval status of their Travel Document. 2. Added a new grouping option in the Crew Calendar by aircraft type. Grouping is based on crew ratings, making it easier to plan rosters for crew members flying different aircraft types. 3. Split the aircraft filter in Crew Calendar into two sections: active and inactive aircraft. ## Wingman and MCP 1. Wingman prompt update – significant improvements addressing real customer use cases, including: - Expanded capability to answer general aviation-related questions based only on selected official sources (ICAO, IATA, FAA, Eurocontrol). - Clearer separation between planning and execution phases, enabling more complex task handling such as generating flight reports. ## OPS 1. Extended Flight Watch (FW) with additional PAX data. It is now possible to enter Adults, Children, Infants, Male, and Female. Previously, only the total number of PAX per flight was available. ## SCHED 1. Added support for handling DEI900–999 elements in SSIM messages. These are custom elements. Operators can define the information exchanged using these elements. In the first version, aircraft registration can be transmitted. Additional flight or aircraft attributes can be easily added upon request.
