You can use git or path deps if you want; or set up your own registry (there is code for it, but I don&#x27;t think it&#x27;s easy to set up yet. IIRC it&#x27;s planned, thoughts welcome!)<p>&gt; Project owners update projects and don&#x27;t bump the version.<p>You cannot update code in a crates.io dep without bumping the version. And new versions only get pulled in when you do a `cargo update` or you update a package which bumps the version number of its dependency.
