At Cloudsmith, we aim to be the central source of truth for your dependencies and package management needs. We've added fully configurable transparent Proxying and Caching support for Debian packages, allowing users to manage their private repositories and upstream sources in one place. This feature provides benefits such as easier setup, isolation, visibility, performance, security, and control over package management. With the addition of Debian upstream proxying, Cloudsmith enables users to configure multiple upstreams with a single repository, fetch and cache packages from upstream repositories, and gain insights into their package dependencies. The new feature is easily accessible through the "Upstream Proxying" menu in Cloudsmith repositories, allowing users to set up and manage their Debian upstreams with minimal configuration.
