On Tuesday, June 18, a new development version of the software, MegaMek was released. The java-based software program can be used to host games of BattleTech over the internet, solo against the AI, or hot-seat.
The latest development version is 0.35.39 and it can be found here, along with a list of changes and bugs fixed.
More than 70 bugs were handled, as well as several minor changes for the game are given. Several alternations of note include the introduction of new tech levels from the Technical Readout: Prototypes. Another new feature is a game option that will allow you to set the year the battle is occurring. If you do, then units not available then are automatically filtered out.
