Oct 1, 2025In October 2025, the snapd team delivered key business-value improvements focused on ConfDB integration, safer installation/removal flows, and CI reliability. Notable work includes API-compatible ConfDB payload changes, improved hook handling to avoid deadlocks with disabled snaps, and updates to developer-facing documentation. Structural safeguards were added to prevent disabling base snaps, and local path installation was refined to bypass unnecessary refresh checks. CI and test automation gained stronger guarantees with formatting enforcement and enhanced debug information to speed troubleshooting. These changes reduce deployment risk, improve API usability for customers, and provide a more resilient foundation for future enhancements.

Apr 1, 2025April 2025 performance/impact: In canonical/snapd, completed the Confdb Ephemeral Data Management Overhaul and exposed Confdb docs, delivering improvements in data integrity, concurrency reliability, and developer onboarding. The overhaul removes pruning for ephemeral data, introduces save/load hooks for ephemeral-affecting changes, enables early concurrency checks, and adds NestedEphemeral to confdb schemas, all contributing to robust unified view IDs and safer concurrent operation. Documentation exposure now makes Confdb docs visible to developers, reducing onboarding time and support loads. These changes reduce data-pruning risks, improve runtime reliability for ephemeral workflows, and accelerate feature development for ephemeral data workflows.

Mar 1, 2025March 2025 — Key outcomes for canonical/snapd: Modernized the Confdb data pipeline with integrated hook/view support and scheduled data loading, enabling asynchronous confdb reads for snap get and improved view handling (query-view/load-view) with refined transaction semantics. Introduced Ephemeral Confdb data support, including tests and a network data schema to manage save/load/changes/query lifecycles. Stability and API consistency improvements included relaxing client timeout checks and aligning confdb-schema naming, reducing false positives and improving developer ergonomics. These changes deliver faster, more reliable config data operations and enable ephemeral data scenarios in networked deployments, reinforcing system reliability and scalability.
