Thanks for the PR! In principle I agree we should keep all dependencies up to date. Unfortunately CI runs into a timeout for the winrt build ... the console output shows this:

    Finished dev [unoptimized + debuginfo] target(s) in 0.04s
     Running `target\debug\examples\test_list_ports.exe`
Available input ports:

Apparently the port enumeration runs into a deadlock or something?
Do you have an idea why this might happen?

I just tried to bisect this: It works with version 0.52 but not version 0.53.
With 0.53 or 0.54 the test applications just hang when they try to do some MIDI operation ...

The windows crate has been updated to 0.56 in #151
