Feb 1, 2026February 2026: Focused on improving test validation, correctness under Proto3, and long-term code quality. Key changes include adding Gson-based JSON validation in YAML tests, refining Protobuf field presence checks with Proto3 explicit presence handling and associated tests, and a broad set of code-quality and maintenance improvements to align with Java 21, dependency upgrades, and static-analysis readiness. These changes reduce regression risk in metadata evolution, improve JSON validation coverage in tests, and streamline ongoing maintenance, contributing to more reliable releases and better performance.

Sep 1, 2025September 2025 was focused on strengthening data security in the fdb-record-layer and stabilizing release governance. Key work delivered centers on encryption key management for serialized data, enabling multi-key support and safer at-rest data handling, alongside a release-notes stabilization effort to ensure artifacts and documentation stay in sync after a publish issue. The work balances cryptographic capability with robust release processes to reduce risk and improve production readiness.

Mar 1, 2025Month: 2025-03 — Focused on upgrade readiness for Protobuf 4 in FoundationDB/fdb-record-layer. Delivered Protobuf 4 Upgrade Preparation by updating deprecated/removed API usage, adopting the new Protobuf API for syntax and edition checks, adjusting text format debug strings to remove newlines, and explicitly adding Guava as a dependency to enable a smooth upgrade path. Minor risk fixes: none reported. Overall impact: establishes upgrade path and reduces upgrade risk for downstream components; enables faster, safer migration to Protobuf 4.

Feb 1, 2025February 2025 summary for FoundationDB/fdb-record-layer: Implemented a dedicated PR coverage workflow to replace the fragile workflow_run-based commenting, markedly increasing the reliability of coverage reporting on PRs and ensuring PR summaries accurately reflect coverage data. Consolidated JaCoCo reports across subprojects into a single top-level artifact and ensured PR data is correctly attributed across forks by propagating PR numbers through artifact-based steps. These changes streamline CI feedback, improve reporting accuracy, and reduce maintenance overhead.
