Release Notes

OpenRocket 22.02.beta.05
(through PR#1688)

New Features
  • C_D Override for subassemblies now implemented. Please test! See this wiki help page for important instructions (fixes #1171)
  • Simulations now properly account for disabled stages (fixes #1477 and #1460)
  • Rail Button improvements:
    • Additional parameters for rail buttons (fixes #1537)
    • Added rail buttons to preset parts database
    • Scaling now supported for rail buttons (fixes #1661)
  • Don't include inactive stages in calculations. Disabling stages using the stage selector buttons now also affects the simulation results. (fixes #1477 and #1460)
  • Mass objects maintain fixed volume when container diameter changes in auto mode (fixes #1315)
  • Inner tubes can have custom inner/outer appearance (fixes #1509)

UI Improvements

Visually select child components of assembly components when selecting the parent (fixes #1489). Try selecting a pod, stage, or booster and see.
  • Significant improvements to preset selection window (fixes #1481)
  • Added sliders to Photo Studio settings (fixes #1524)
  • Show markers for pods and boosters in rocket side view (fixes #1146)

    • When setting focus to a spinner field, select the entire field by default (fixes #1506)
    • After selecting a preset, automatically highlight most commonly edited parameter (fixes #1488). So, for example, after selecting a body tube preset the Length parameter will be selected by default.
    • Restore focus to motors, recovery, stage and simulation tables after table action and others (fixes #1558). Simply put, you shouldn't need to click in the table areas just to enable keyboard shortcuts to work.
    • Use tab and arrow keys to traverse sim table (fixes #1552)
  • Added and/or improved hover texts on a bunch of different buttons and controls
  • Apply preset after double-clicking (fixes #1539)

Known Issues

Bugs and feature requests are 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.
  1. Backward compatibility: During the beta period, any design saved from the beta app should open correctly in 15.03, provided none of the new rocket design features are used. There will be some warnings upon opening the file.
  2. Java compatibility: This release of OpenRocket is guaranteed to work correctly with Java 11 and 17. As of beta 4, the packaged versions come with Java 11, and the JAR file supports either 11 or 17. Java 17 is known to have problems, but the JAR allows it if folks want to experiment. Other Java versions are not guaranteed to work correctly. (issue 1022).
  3. Packaged Installers:
    • Packages need to be signed (issue 1144)
    • File association with .ORK files is not yet working properly (issue 1135)
    • Desktop shortcut creation on Windows doesn’t seem to be working
  4. 3D Views:
    • Click-selection of components in 3D views does not work properly, and causes some strange visual behavior (issues 966, 939, 1054)
    • 3D views black out during window resizing (issue 1080)
    • 3D views may not show properly on external monitors (issue 864)
  5. Exports and Printing:
    • Decal export will only export the first decal found (issue 823)
    • Report may not include all transitions (357)
  6. Fins:
    • Fin roots displayed in unexpected ways on transitions (issue 1021)
    • Fin tabs on transitions may not display correctly
    • Tube fin CP calculation still needs work
  7. Photo Studio
    • Smoke effect may not function properly (issue 874)
    • Turning flame effect on and off can have strange effects on decal display (issue 1122)
  8. Simulation
    • Asymmetric thrust is not simulated correctly (issue 1062)
    • Plot of side force coefficient is constant at zero (issue 1060)
    • (added 2/26) Drag coefficient override of whole stage does not affect sim results (issue 1171)
    • (added 3/2) Tube fin sim results differ from 15.03 (issue 1207)
    • (added 2/26) Need to click on motor configuration to get flight data (issue 1175)
    • (added 2/26) CP calculations with fins-on-transitions less accurate (issue 1173)
    • (added 2/26) Doesn't create new simulation from new configuration reliably (issue 1163)
  9. User Interface
    • Selection buttons may be hard to read (issues 988, 1099)
  10. Motors
    • Closed issues
      • (added 2/26) Some configured motors not recognized properly (especially CTI) (issue 1174)

    • (added 2/26) Sign flip in position offset for fins when importing Rocksim file (issue 1164)
    • (added 3/4) Fins get miniaturized when importing (issue 1220)
  12. Other

    • Double-clicks may not work correctly on Macs using mouse (issue 908)

Downloaded, it runs. Windows doesn't like something and recommend against installing....just click on More Info in the splash screen and click Run Anyways.
Both MacOS and Windows want code signing keys or they give security warnings. Unfortunately, we have not been able to find a way to get a code signing key that doesn't cost money.
 
Downloaded, it runs. Windows doesn't like something and recommend against installing....just click on More Info in the splash screen and click Run Anyways.

Launch it with the java command line, i.e.

"C:\Program Files\Eclipse Adoptium\jdk-8.0.312.7-hotspot\bin\java" -Dsun.java2d.d3d=false -jar OpenRocket-15.03.jar
 
Known Issues

  1. Java compatibility: This release of OpenRocket is guaranteed to work correctly with Java 11, and that is what the packaged versions come with (please use the packaged versions!). Older or newer Java versions are not guaranteed to work correctly. (issue 1022)

Guess I'll have to download the source and apply all my gradle and upgrade changes, because I had it working under at least 3 or 4 version of Java.
 
Great Job Guys!

It's opening my old developer's test sims... but with some minor issues. 3D view doesn't fill the window.

Here's my unfinished Estes Trident (K-33)

With this version though, we should be able to do accurate (looking) wedge fins. Maybe not accurate flight data for them, but get the right appearance.

Now, as for flight data? I don't know... I work weekends, and have to get ready for work... So, that kind of stuff will have to wait.

Key word "guaranteed". If you want to run the raw jar (not recommended for most users) you'll find others also work.

Why? "Installers" are not doing anything more than running "java -jar" anyways. Unless you are specifying some command line parameters for the heap, etc.
If you don't use any of the new features, 15.03 will open a design successfully though it will give lots of warnings. If you use new features they will be ignored when you open under 15.03.

Yeah, saw after I had posted. That was not always the case with the unstable branch, thus the question.
 
Launch it with the java command line, i.e.

"C:\Program Files\Eclipse Adoptium\jdk-8.0.312.7-hotspot\bin\java" -Dsun.java2d.d3d=false -jar OpenRocket-15.03.jar
The package installer worked fine, people just need to be aware of the Windows splash screen and to click More Info so they can get the Run Anyways button to appear.

Are you running some specific jvm parameters? I didn't see any installer configuration on the unstable branch in github (well except snap :|).
 
Are people getting their files for the new version from this location:

https://wiki.openrocket.info/Downloading_&_Installing
Github has the "unstable" version afaict.
We're going to have to rename that branch... it's where the development has been for quite a while now. Oh, this is a surprise: because this is a Beta, we put the "Pre release" tag on the release. So, github is still showing 15.03 as the latest relese -- if you follow the releases link on that page, you'll find the new release.

I just want to make sure people dont have issues locating the proper file(s).
 
Ah... Ok... Found the correct version... Same issue...

OH... I like that the CG/CP marks are not on the rocket in 3D finished!!!
