22.7.2011: Version 1.1.7 is released!
This release includes automatic rocket design optimization support (Analyze → Rocket optimization). You can optimize any amount of rocket parameters for apogee altitude, maximum velocity or a number of different values.
While the automatic optimization is a powerful tool, it is very easy to optimize against particulars of the simulation methods, instead of true physical phenomena. Always keep common sense at hand and take the results with a grain of salt.
22.7.2011: Version 1.1.6 is released!
This release includes initial localization support and translations to French, German and Spanish. This is thanks to the great work of Boris du Reau, and the teams from Tripoli France, Tripoli Spain and ERIG e.V. If you prefer to use some other language than the system default, you can select the language on the "Options" tab of the preferences dialog.
The release also includes design scaling support and numerous bug fixes.
