I’m working to update my code from Julia 0.6.3 to 0.7/1.0, and I’m running into an issue with ReverseDiffSparse.jl. I do not directly use this module, but my code does use JuMP and Ipopt.

It appears that ReverseDiffSparse.jl attempts to call Base.gamma, which was moved to SpecialFunctions.jl in the update to 0.7. Is this an issue that is solvable on my end?

Here is the warning message:

```julia
 WARNING: importing deprecated binding Base.gamma into ReverseDiffSparse.

```
