I am wondering what is blocking an update, I saw a few issues that were blocking for the packaging on the repo but all of them are fixed, and dependencies are now standard and up-to-date.

Hello!

I've had a brief look with cargo-debstatus[0], which matches the dependency tree 
against the crates that are available in the Debian source code archive (with 
--no-default-features to get the minimum set of libraries necessary to update):

It seems the following need to be packaged for Debian first:

- portable-pty
- serial2
- unicode-display-width

The others we would need to try if e.g. derive_more 2.X.X can be replaced with 
derive_more 1.X.X, to avoid needing to do a coordinated derive_more update as 
well. For example, nix 0.31 and 0.30 are usually trivially interchangeable, and 
it's similar for criterion.
