OpenRocket 1.1.9 (2011-11-24):
-------------------------------
This release calculates rocket flight in real-world coordinates and
takes into account geodetic effects (including coriolis effect) thanks
to work by Richard Graham. Printing of transitions, nose cone
profiles and fin marking guides is available thanks to Doug Pedrick.
It also contains some usability features and bug fixes.
OpenRocket 1.1.8 (2011-08-25):

<p>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.</p>
