50 <p>For this release a major part of the simulator code has been
51 rewritten for better flexibility in future development. It also
52 includes a vastly improved thrust curve selection dialog, the
53 possibility to loading user-defined thrust curves and better
54 startup times than previous releases.</p>

67 bug fixes. It is also a stable milestone, after which development

98 <p>Occasionally during OpenRocket development focus will shift
99 from feature development towards getting all open bugs fix and
100 to produce a stable release. No updates are made to the
101 stable branch except for possible bug fixes, so the stable
