51 <p><span class="date">24.11.2011:</span> Version 1.1.9 is
52 <a href="download.html">released</a>!</p>
53 <p>For this version Richard Graham has implemented geodetic
54 computation methods, which take into account the curvature of the
55 Earth and the coriolis effect. The computation method is selected
56 by the <em>Geodetic calculations</em> option in the simulation
57 options. It's not <em>(yet)</em> a full spherical computation model, but
58 should be accurate enough for almost all sub-orbital needs.</p>
59 <p>Doug Pedrick has also enhanced the printing system with the
60 ability to print fin positioning guides, transition templates and
61 nose cone profiles. Other smaller enhancements and bug fixes are
63 <p><span class="date">25.8.2011:</span> Version 1.1.8 is
64 <a href="download.html">released</a>!</p>
65 <p>This release contains bug fixes to the optimization methods.
66 It also contains a workaround to a JRE bug that prevents running
67 OpenRocket on some builds of Java 7.</p>
68 <p>The web pages have also been somewhat updated and Boris du Reau has
69 created <a href="http://openrocket.trans.free.fr/">a separate site</a>
70 for coordinating the localization efforts for OpenRocket.</p>
71 <p><span class="date">12.8.2011:</span> Version 1.1.7 is
72 <a href="download.html">released</a>!</p>
73 <p>This release includes automatic rocket design optimization
74 support (<em>Analyze</em> → <em>Rocket optimization</em>).
75 You can optimize any amount of rocket parameters for apogee
76 altitude, maximum velocity or a number of different values.</p>
77 <p>While the automatic optimization is a powerful tool, it is very
78 easy to optimize against particulars of the simulation methods,
79 instead of true physical phenomena. Always keep common sense at
80 hand and take the results with a grain of salt.</p>

83 <h2>Ready packages</h2>
84 <p>These are packages ready for use and are the recommended
85 download for normal users. They are pre-packaged with motor
87 <a href="http://www.thrustcurve.org/">thrustcurve.org</a>.</p>
88 <p>OpenRocket requires <strong>Java version 6</strong> or
89 later. The Sun Java Runtime is recommended.</p>
90 <h3>Development release</h3>
91 <p>The development release contains the latest and greatest
92 features, but may contain more bugs than the stable version.

108 <h3>Stable release</h3>
109 <p>Occasionally during OpenRocket development focus will shift
110 from feature development towards getting all open bugs fix and
111 to produce a stable release. No updates are made to the
112 stable branch except for possible bug fixes, so the stable
113 release has less features than the development release.</p>
114 <p>The current stable release is

117 <h3>Running OpenRocket</h3>
118 <p>OpenRocket can be started in most graphical environments (including
119 Windows) by double-clicking the package icon. No installation is
121 <p>From the command line OpenRocket can be started by
