WebSocket demo doesn't work with latest (0.12) version of actix

[yatesco]

Hi there, the examples at https://github.com/actix/examples/tree/master/websockets all use actix="0.10". Changing this to actix="0.12" fails because the context is no longer implemented against the struct correctly:

I had a look at the actix project but I couldn't see a list of CHANGES.md so I'm a bit stumped.

Are they incompatible and should I just stick with actix="0.10" for now, or is there an example of how to upgrade?

Thanks!

Yes they are incompatible. Upgrade paths will be documented after to Actix Web v4 stable release.

As you pointed out, use 0.10 for now.
