**We have just started rolling out a new version of Leon. Over the next few days, customers will be gradually switched to a new version. If you find a function not working as expected, please let us know via the [Customer Portal](https://customer.leon.aero/)**

**SALES**

- FLIGHTS FOR OWNER - in the Sales tab in the Admin Panel -> Fleet there will be a possibility to select 'Default client for owner flights'. While adding Trip in the OPS module with 'Flight for owner type' the defined client will be added by default to the Trip. For Trips booked from the Sales module, standard automatization will work
- RESERVATION - while adding Aircraft Reservation from the Sales or OPS module there will be a possibility to define the timezone UTC or Local Time in the upper part of the window

**OPS**

- OVERFLIGHT PERMITS - in case a ForeFlight integration is enabled, the 'GET COUNTRY LIST' button in the Overflight Permit(s) OPS Checklist item will add countries based on the integration data
- FLIGHT WATCH - auto-filling of 'BLOCK ON' time will be possible with Eurocontrol integration enabled. Calculation will be based on ETA from Eurocontrol and TAXI IN time from the Airport Directory

**CREW**

- CREW CALENDAR - when a crew member will be added to a flight that is crossing midnight there will be an arrow visible next to the aircraft icon in the duty box

**MX**

- SCHEDULED MAINTENANCE - while adding a Maintenance there will be a possibility to define the timezone UTC or Local Time in the upper part of the window

**Apart from the above-mentioned features, we have also made changes to Leon API which can be reviewed under this [changelog](https://bitbucket.org/leondevteam/api-documentation/src/master/changelogs/changelog-155.txt) link**
