I recently upgraded to v1.5, and tried to weave a document. When I reloaded Weave, and tried using I got this warning, and it won’t start a document. I tried updating my packages, do I need fix something in Weave, is weave the best option for changing markdown or .jl files to another format?

```julia
using Weave

Weave works on v1.5. You might need to update the packages? At least the latest version works (I use it daily).

I have seen this warning with `Weave.jl` as well. It doesn’t seem to stop the package working correctly though.

I reinstalled it, I thought it should work. Not sure why it’s not.

I think I just needed to restart it. It’s completely different than v1.3 looks like it does loads in parallel now.

All I did was upgrade to the latest version and restart VS.
