Default ANNOUNCEMENT: OpenRocket version 22.02 Public Beta is underway: Download it now!

The OpenRocket team is very excited to announce that the new version of OpenRocket is at long last available for everyone to try. For now this is a public beta, which means that there are known issues still to be worked out before the final release. Nonetheless, the current version is stable and usable enough for most folks to start using it full-time.

Downloading links and detailed installation instructions are on the wiki: https://wiki.openrocket.info/Downloading_%26_Installing
Release notes: https://openrocket.info/release_notes.html

Here are the major new features:

- Pods!
- Drop-off boosters!
- Rail buttons!
- Attach freeform fins to nose cones and transitions!
- Coefficient of Drag override!
- Dave Cook’s fantastic rocket component library now included!

plus endless smaller things to make day-to-day use more enjoyable.

The beta is being released in both packaged form and as a plain JAR file (for use with Java 11 only), at the link provided above. We strongly recommend the packaged installers for most folks. Updated builds will be made available periodically during the beta period. OpenRocket can check for updates either automatically at startup, or manually. The settings for this feature are found at: Edit > Preferences > General.


This update has taken a long effort from a lot of people. Please give it a try, and let us know what you think. We hope to get back on a more regular release schedule (!) going forward.

Thanks for your continued support!

Known Issues at the Time of Release

This list will be updated on a sticky thread over at The Rocketry Forum: https://www.rocketryforum.com/threa...-it-now.171295/.

Bugs and feature requests are officially tracked on Github (https://github.com/openrocket/openrocket/issues). If you encounter a problem, please check this list first before filing a new issue. If you would prefer to just report and/or discuss it in this thread, that’s fine too. Also be sure you’re running the latest version before reporting.

See referenced issue numbers in Github for more details on each item below.
