My code now generates this warning. It still runs but I would like to understand why and if there is a way to make Julia happy and have the warning go away. I am using the latest Julia on Atom, on Windows 10.

Code is after the warning.

The warning happens in `OrdinaryDiffEq` and is thus not a consequence of your user code. Either `OrdinaryDiffEq` needs an update, or you must run `] up` to update your installed version of `OrdinaryDiffEq`

Edit: I created an [issue](https://github.com/JuliaDiffEq/OrdinaryDiffEq.jl/issues/592) in `OrdinaryDiffEq` to track progress. It is indeed `OrdinaryDiffEq` that requires an update.

Hopefully this PR solves the problem  
[https://github.com/JuliaDiffEq/OrdinaryDiffEq.jl/pull/593](https://github.com/JuliaDiffEq/OrdinaryDiffEq.jl/pull/593)

Edit: This PR has now been merged and the warning should go away if you temporarily check out master branch  
`] add OrdinaryDiffEq#master`

Yup this was fixed. DataStructures.jl updated and deprecated a feature we used, so we changed according to their deprecation and there should be a new version out which doesn’t throw the warning. Release should be fine now, so there shouldn’t be a need to `] add OrdinaryDiffEq#master`

I ran `] add OrdinaryDiffEq#master` yesterday - is this okay or could it cause problems down the road? I don’t understand what `#master` does.

`] add OrdinaryDiffEq#master` checks out the master branch of the repository. This branch will in general have slightly worse guarantees of working well together with other packages, so if you want to have a hassle-free environment, you can now `] add OrdinaryDiffEq` to check out the latest tagged release (you might have to `] update` first).

`] add OrdinaryDiffEq#master` will get you our current in-development code before it’s released. Of course, that should be done with caution, but if you want the bleeding edge it’s there.

I have tried ] update and ] add OrdinaryDiffEq and I am still getting this warning.

Have you restarted Julia? Otherwise, Maybe some package is holding you back. You could try to check out the master branch for a while to see if the problem goes away. What version of Ordinarydiffeq do you have,? Check. `] st`

You should use `]up`. Those versions are old.
