28.9.2012: Version 12.09.1 is
+ released! This is a bug-fix release,
+ fixing numerous bugs introduced in 12.09. The only new feature is
+ the option to automatically open the latest design file on startup
+ (in Edit → Preferences → Options).
+
23.9.2012: Version 12.09 for Android is
+ released! The major improvement is the
+ possibility to edit simulation parameters, thanks to work by Kevin
+ Ruland.

+
+
10.3.2012: Version 12.03 for desktop
+ and Android is released!
+
In this release the version numbering scheme has been changed.
+ From now on the version number is YY.MM indicating the
+ year and month of the release. Bug fix releases are indicated by
+ an added ".1".
+
This also marks the first release for Android devices. In this
+ first release you can open files and examine existing simulations,
+ stability data and motor files. The Android port is thanks to
+ work by Kevin Ruland.
+
Enhancements in the desktop version include saving designs in RKT
+ format thanks to Doug Pedrick, freeform fin set import form images
+ by Jason Blood, configurable stage separation
+ events, guided help tours and displaying the computed motor
+ designation class. The application has also been translated to
+ Italian by Mauro Biasutti and Russian by the Sky Dart Team.
+
24.11.2011: Version 1.1.9 is
+ released!
+
For this version Richard Graham has implemented geodetic
+ computation methods, which take into account the curvature of the
+ Earth and the coriolis effect. The computation method is selected
+ by the Geodetic calculations option in the simulation
+ options. It's not (yet) a full spherical computation model, but
+ should be accurate enough for almost all sub-orbital needs.
+
Doug Pedrick has also enhanced the printing system with the
+ ability to print fin positioning guides, transition templates and
+ nose cone profiles. Other smaller enhancements and bug fixes are
+ also included.
+
25.8.2011: Version 1.1.8 is
+ released!
+
This release contains bug fixes to the optimization methods.
+ It also contains a workaround to a JRE bug that prevents running
+ OpenRocket on some builds of Java 7.
+
The web pages have also been somewhat updated and Boris du Reau has
+ created a separate site
+ for coordinating the localization efforts for OpenRocket.
+
12.8.2011: 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.
+
10.6.2011: Version 1.1.5 is
+ released!
+
This release includes updates to the printing system which fixes
+ printing on Windows.
+
5.3.2011: Version 1.1.4 is
+ released!
+
This release includes initial printing support, thanks to Doug
+ Pedrick. Printing still has a few issues on some platforms.
+ Various bugs have also been fixed.
+
6.10.2010: Version 1.1.3 is
+ released!
+
This release includes support for moving and copying components
+ in the component tree using drag-and-drop. Use normal DnD for
+ moving, and control-drag for copy. This release also fixes a
+ severe bug in the undo system.
+
7.9.2010: A bug-fix version 1.1.2 is
+ released!
+
This release fixes a severe bug in 1.1.1 that prevented adding stages
+ to rocket designs. Users are recommended to upgrade.
+
3.9.2010: Version 1.1.1 is
+ released!
+
For this release a major part of the simulator code has been
+ rewritten for better flexibility in future development. It also
+ includes a vastly improved thrust curve selection dialog, the
+ possibility to loading user-defined thrust curves and better
+ startup times than previous releases.
+
Simulation listeners written for older versions of OpenRocket
+ are not compatible with this release.
+
21.3.2010: Version 1.1.0 is
+ released!
+
This release includes the first support for loading RockSim
+ rocket design files (.RKT), thanks to contributions by Doug
+ Pedrick. It's also the kick-off of the 1.1 development branch of
+ OpenRocket.
+
10.3.2010: Version 1.0.0 is
+ released!
+
This release includes several hundred new thrustcurves from
+ thrustcurve.org and some
+ bug fixes. It is also a stable milestone, after which development
+ on larger features will be started in a 1.1 branch. Look out
+ for it! :-)
+
17.2.2010: Version 0.9.6 is
+ released!

+ more in line with the Barrowman method and enhances the simulation
+ time step selection, in addition to fixing numerous bugs.
+
28.11.2009: Version 0.9.5 is
+ released!
+
This release fixes a serious bug in 0.9.4 that
+ prevented adding a tube coupler and centering ring to the same
+ body tube, in addition to a few smaller additions. Users of
+ 0.9.4 should upgrade immediately!
+
24.11.2009: Version 0.9.4 is
+ released!
+
This version adds support for through-the-wall fin tabs,
+ attaching components to coupler tubes, material editing, automatic
+ update checking, in addition to fixing numerous bugs.
+
1.9.2009: Version 0.9.3 is
+ released!

+ data exporting, showing flight events in plots, example rocket designs,
+ splitting clustered inner tubes and automated bug reporting.
+

+ released!
+
This version includes bug fixes for imperial unit
+ conversions and UI improvements for motor selection.
+ All users of imperial units should upgrade!
+
9.6.2009: The
+ Master's thesis for which OpenRocket
+ was written for is now available!
