Error precompiling Altro: LoadError: UndefVarError: QuadraticObjective not defined

[grotli]

When try to precompile Altro (that is run "using Altro") I get the error message below. Do you have any suggestion on what I should do?

Yes, I'm currently working on the fix for this. The new release should be out in the next couple days.

I am also experiencing this error while running the Cartpole.ipynb example. I guess it is a version issue.

Any update on this since February? Also experiencing this issue

[bjack205]

This has been fixed in the most recent releases of the packages: Altro 0.4.0, TrajectoryOptimization 0.5.0.

Thank you for the fix! The update has not appeared in the Julia package manager Pkg. Are the packages no longer registered, or is a specific version of Julia required? I am using v1.5.3, and the current versions are Altro v0.3.0 and TrajectoryOptimization c0.4.2
