Mar 1, 2026March 2026 monthly summary for canonical/snapd: Delivered key CI/CD, security, packaging, and testing infrastructure improvements that directly increase release reliability, cross-architecture compatibility, and developer velocity. Highlights include stabilizing the static analysis workflow in CI (weekly runs, additional symlink, pinned staticcheck version, enhanced coverage tooling); firmware secboot enhancements to improve FDE reliability and event-type handling; packaging hardening for Ubuntu 16.04 to achieve dep17 compliance and improved systemd unit installation; migration of the testing framework to spread-plus with standardized qemu-system usage; and expansion of CI to include C code coverage for deeper quality signals. These efforts reduce CI noise, prevent regressions across architectures, and enable faster, safer releases across supported platforms.

Feb 1, 2026February 2026 summary for canonical/snapd focusing on delivering security, reliability, and release-readiness improvements. Key work spanned camera interface hardening, test infrastructure and upgrade-compatibility work, and packaging/release processes. Notable outcomes include improved device access control for camera (/dev/video), enlarged test coverage with bigger nested disk scenarios, and stabilizing upgrade/compatibility tests for main and upgrade paths. Release workflow adjustments were executed to bump to 2.74.1 and subsequently revert to address issues, complemented by a corrected deb release flow. Additional infrastructure refinements included adjusting mkversion.sh for deb packaging, and targeted test reliability improvements such as cloud-init workarounds and encrypted setup flow improvements, all contributing to higher security, reliability, and faster release cycles.

Dec 1, 2025December 2025: Delivered features that expand testing coverage, improve observability, and strengthen secure installation, while eliminating a cooperation pain point in hybrid TPM/fde preinstall checks. Specifically, added OpenStack backend support to the nested testing framework; enhanced logging for standby operations to improve visibility and troubleshooting; and upgraded secboot to expose preinstall check results and optimize PCR sealing for reliable installations. Fixed a bug where API calls in hybrid-tpm-fde-preinstall-check were interrupted by standby, smoothing preinstall workflows for hybrid systems. Business value includes broader OpenStack test coverage, faster issue diagnosis, and more secure, repeatable installations.

Feb 1, 2025February 2025 (2025-02) monthly summary for canonical/snapd: Delivered the Snapd 2.68.x release series with baseline 2.68 and patch releases (2.68.1/2.68.2), delivering security, performance, and compatibility improvements such as FDE enhancements, improved AppArmor prompting, Confdb experiments, expanded snap component support, bootstrapping and image prep refinements, and backend/interface updates. Implemented critical ARM-related fixes and tightened system safeguards: armhf type specifier fixes in snap-confine, ensuring correct time/value representations on ARM builds. Enforced stricter hook configuration rules for core/system snaps, with tests and validation to prevent improper usage. Reverted kernel/asset remodeling changes to preserve correct kernel/asset update behavior, correcting task dependencies. Overall, these efforts increased security, stability, and upgrade predictability, while maintaining compatibility across architectures and improving build integrity.

Dec 1, 2024December 2024: Delivered a production-ready Snapd 2.67 release with security/interface improvements and updated CI/build environment (Go version bumps, workflow updates) to ensure consistent builds. Aligned Ubuntu test environment so systemd-dev is optional in 24.10+ to reflect current packaging. Hardened the test suite and CI reliability (skip logic, non-cached core testing, clearer messaging, robust version regexes across formats), reducing flaky tests and speeding up release cycles. Overall, improved release quality, reliability, and packaging alignment, enabling faster delivery of secure features.
