hello world project from readme, use cargo +beta run, and got:

We've discussed this in chat, and we'll be putting out a 0.99.8 release ahead of schedule to address this. Thanks for reporting!

Run into the same issue myself. Before the release of 0.99.8, a temporary workaround is to pin futures crate versions oneself if possible by adding:

futures-core-preview = "=0.3.0-alpha.18"
futures-io-preview = "=0.3.0-alpha.18"

to project's dependencies.

I published 0.99.8 with the fix mentioned above. Thanks for the report!
