Python projects will now see more complete and accurate transitive dependency trees in their dependency graphs and Software Bills of Materials (SBOMs).

This feature is based on a new type of Dependabot job that builds a dependency snapshot and uploads it to the Dependency Submission API. It’s similar to dependency autosubmission, but it does not incur charges for actions minutes and can access organization-wide configurations for private registries you’ve set up for Dependabot.

This release supports all the major package managers for Python, including pip, uv, and Poetry (v1 and v2).
