**A new beta version of Leon has just been released. You can check it under [beta.leon.aero](http://beta.leon.aero/)** **web address and follow a list of changes below. If you find a function not working as expected, please write an e-mail to [](https://www.leonsoftware.com/javascript:/*%20This%20email%20address%20is%20being%20protected%20from%20spambots.*/).

- DOCUMENTS MANAGER - we have added Trip Sheet to the 'Documents Manager' panel in Leon. Only Leon default Trip Sheet version can be managed in this section
- CREW PANEL - flight information (schedule & crew assigned) appears now at the bottom of the screen (previously it was in a pop-up window)
- SLOTS - Leon will change both ADEP & ADES slots statuses in the checklist to '?' if ADEP has been changed
