ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.
                                                                                                                                                                                                
We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.                                                                                                                                                                                                                                             

nmigen-yosys 0.9.post3527.dev26 requires wasmtime~=0.19.0, but you'll have wasmtime 0.20.0 which is incompatible.**

I'm following Semantic Versioning, which requires me to use dependencies strict enough that they do not consider 0.(x+1) compatible at the time when only 0.x is released. I've already updated nmigen-yosys to be compatible with wasmtime 0.20.0, so there's no actual issue--just upgrade nmigen-yosys.
