A post to the Eagle Dynamics forums has word that version 1.5.0 of DCS World is now available in open beta, offering the chance to test fly updates to this combat flight simulation that includes a graphics revamp (thanks InBlack). They also announce that open beta testing is underway for their L-39 Albatros module that adds this light jet to the game. This page is where to find the downloads along with details on testing, and this video shows off the L-39 Albatros.
