Meuse 1.2.0 released!

I released today the version 1.2.0 of Meuse, your favorite Rust private registry for your crates.

What’s new

More security

Meuse needs some secrets in its configuration file, for example the PostgreSQL database password, or your S3 credentials if you are using the S3 backend for your crates.

This release allows you to set a new !secret (or !envsecret to read a value from an environment variable) YAML tags for your secrets in the configuration file.
This will indicate to Meuse that the value is a secret. If this value is leaked by mistake by the program (like printed somewhere), the secret will be replaced by a << cloaked >> string.

You may think "but why would the secret be logged/printed at the first place" ? Meuse will indeed not do that, but a mistake or a bug can happen, so I recommand you to use these tags.

New/Better metrics

New metrics were added to Meuse, and some we renamed.

Today, Meuse exposes tons of metrics, for example:

  • Internal metrics about the process, threads…​

  • HTTP requests duration and count per endpoint

  • HTTP response count per endpoint/status code

  • Metrics about the Git index (operations count and duration)

  • Number of crates, crates versions, users and downloads for the registry

Everything is exposed on /metrics, in Prometheus format.


An user found a bug when uploading on Meuse crates with dependencies renamed. The issue is now solved.

More information

You can find more information about Meuse on the project website, and the code is available on Github.
