Yes, 1.0.4 is the latest public Beta, but I am going to release 1.0.5 till Friday. However, no significant new features there, just some fixes and little enhancements, for example showing on map delayed take-offs /if applicable/, distance of EA from airfield for take off trigger in gai type mission. When user wants to add new formation he can immediatelly check on the map the airfield location where the unit is currently stationed, etc.).
I am open to your suggestions and feature requests.
