## Summary
Mozilla has announced a new batch of updates to its Bugzilla (BMO) infrastructure, affecting how the bug tracking system handles API requests and data exports. The update includes a significant migration of Bug REST resources, specifically regarding attachment management, toward the native Mojo API.

Beyond API changes, the update addresses data reliability in the Extract, Transform, Load (ETL) pipeline and improves documentation workflows. These changes impact Mozilla developers, contributors, and automated tooling that interact with the Bugzilla ecosystem for issue tracking and data analysis.

## Technical updates to Bugzilla infrastructure
- **API Migration:** The Bug REST resource for attachments (including adding and updating attachments) has been migrated to the native Mojo API.
- **Data Integrity:** The BMO-ETL process now implements a full snapshot rollback if any individual table fails to export, preventing inconsistent data in dashboards and charts.
- **Documentation Workflow:** Project documentation is being migrated from reStructuredText (rst) to Markdown and will be hosted directly within Bugzilla.
- **Security and Access Control:** User group visibility via the `/rest/user?names=` endpoint has been restricted to the `can_see_groups` permission level.
- **Logging and Observability:** Fixes were applied to `log_user_request` to address instances where Mojo API routes were logging empty request URLs and user agents.

## Why it matters
These updates improve the stability and security of the tooling used by the global open-source community to report and track bugs in Mozilla projects. The transition to Mojo APIs and Markdown documentation aligns the bug tracker with modern web development standards and improves developer experience.
