Upgrade from 0.7.8 to 0.8.2, need reactive_graph now?

[nlfiedler]

Sorry, every time I upgrade Leptos I run into problems and I have to ask for help here. My apologies for failing as a developer. As the summary says, I'm upgrading Leptos from 0.7.8 to 0.8.2 and now every page fails to build with errors similar to this:

error[E0599]: the method `get` exists for struct `Signal<Vec<SendWrapper<File>>>`, but its trait bounds were not satisfied

    = note: the following trait bounds were not satisfied:

help: trait `Get` which provides `get` is implemented but not in scope; perhaps you want to import it
    |
4   + use reactive_graph::traits::Get;
    |

(The errors are all slightly different, it's not just get() and it's not just web_sys::File.)

Should I add reactive_graph as a dependency and explicitly use the traits? That seems odd since the changelog and the book don't mention this at all. I'm guessing doing something subtly wrong but I seem to be the only one having this problem.

The existing code is at https://github.com/nlfiedler/tanuki/tree/main/src/preso/leptos if you want to see the most recent version.

Thank you in advance.

These sorts of errors typically occur when you have mismatched versions of Leptos in your dependencies: for example, if you upgrade leptos from 0.7 to 0.8 but forgot to update leptos_router from 0.7 to 0.8, or when you update all the leptos dependencies but are using another library in the ecosystem that depends on 0.7 and also needs to be updated. For example when you update leptos from 0.7 to 0.8 you need to update leptos-use from 0.15 to 0.16 (see here)

Thank you, thank you. It was indeed the leptos-use and it seems that version 0.16 is not released yet, so I'll just keep waiting.
