May 2026 monthly summary for open-quantum-safe/liboqs: Focused on maintainability and upstream alignment through a targeted refactor that moves dependency handling logic from Jinja templates into Python. This reduces template complexity, improves testability, and lays groundwork for safer upgrades.

April 2026 highlights for open-quantum-safe/liboqs: - Key feature delivered: Upstream MAYO algorithm update and NIST compliance. Code and documentation updated to reflect latest upstream changes, aligning with NIST standards and improving the overall MAYO implementation. Commit reference: ba66c3b00c65ef0d36564b1e82d57d1effe36a72. - Major bugs fixed: None reported this month. - Overall impact and accomplishments: Provides NIST-aligned MAYO changes, enhancing compliance, reliability, and interoperability for downstream users; reduces future maintenance risk by aligning with upstream evolution; positions liboqs for upcoming standard updates. - Technologies/skills demonstrated: upstream integration, cryptographic algorithm alignment, thorough testing (full and extended tests), documentation updates, and code review/sign-off practices.

2026-03: Implemented memory-optimized build pathway for Open Quantum Safe liboqs and tightened build quality across CI, docs, and templates. Delivered a new build option (OQS_MEMOPT_BUILD) enabling memory-optimized implementations, with corresponding CMake option, oqsconfig define, and upstream META.yml tagging. Updated CI matrix and documentation to support and clarify the feature; adjusted copy-from-upstream scripts for consistency; and improved template handling. Also fixed BOM generation collisions and applied code-quality improvements (formatting fixes in generated code and simplified Jinja templates) to reduce maintenance burden. Overall, these changes enable memory-efficient deployments while increasing build reliability and traceability.

October 2025: Delivered reliability and test-stability improvements for SLH-DSA in liboqs, addressing weekly test failures and memory safety concerns, tuning CI pipelines, and updating templates for correct address sizes and constant-time tests. These changes reduced flaky tests, improved CI throughput, and reinforced cryptographic correctness.

In September 2025, completed the re-enablement of the full ACVP test suite in open-quantum-safe/liboqs, restoring pytest.main as the test driver to run all ACVP tests. This fix ensures complete test coverage, earlier detection of regressions, and more reliable validation of ACVP workflows. The change is captured in commit dd942d434463872193ba282250532ac0be15f1e3 with message 'Re-enable all ACVP tests [full tests] (#2283)'. Key impact includes improved CI reliability, higher quality gates, and faster feedback for developers working on ACVP-related validation.

April 2025 delivered governance and attribution improvements in the mlkem-c-aarch64 repo, including adding Basil Hess to the RELICENSE.md contributor list, aligning with license compliance practices, and reinforcing project transparency.

March 2025 monthly summary focusing on delivering NIST Round 2 aligned updates for MAYO and UOV with ARM64 NEON optimizations, plus documentation and spec version changes. These efforts enhance compliance, performance, and platform coverage for liboqs, supporting faster validation and broader adoption.

February 2025 monthly summary for open-quantum-safe/liboqs. Focused on stabilizing CI workflows and delivering significant cryptographic feature work. Highlights include a CI reliability improvement and the introduction of ML-KEM integration with optimized native backends and comprehensive testing across architectures, aligning with performance and standards goals.

January 2025: Focused on stabilizing cross-platform builds for pq-code-package/mlkem-c-aarch64. Implemented a Windows MSVC inline compatibility fix by replacing generic inline attributes with MSVC-specific __forceinline and __inline in sys.h, addressing compile-time inlining issues and ensuring consistent optimization across Windows. This change reduces Windows build failures, simplifies maintenance, and strengthens the repository's cross-compiler reliability. The work preserves inlining semantics and aligns with performance goals. Commit reference: 9001b42d0d14c79499a6ab8626e8498ec69a1d2e.

December 2024 monthly summary for pq-code-package/mlkem-c-aarch64 focusing on a targeted correctness fix in matrix entry generation and overall reliability improvements. Delivered a high-impact bug fix with clear commits and increased confidence in low-level cryptographic computation.

2024-11 Monthly summary for open-quantum-safe/liboqs focusing on reliability, compliance, and technical delivery. Key actions included restoring CI build workflow, s390x cross-compilation policy, and delivering ML-DSA update per FIPS 204 with API/ACVP test enhancements. These efforts improved release confidence, reduced risk, and strengthened interoperability.
