February 2026 Monthly Summary — ydb-platform/ydb. Focus: stability, compatibility, and reproducible builds. No new feature releases this month; primary work centered on dependency drift mitigation to ensure ongoing project compatibility and CI reliability. Key deliverable: Build Dependency Compatibility: Protobuf Version Alignment. Aligned protobuf version in the build configuration from 3.21.12 to 3.20.3 to satisfy current project requirements, preventing incompatible protobufs from entering the build. Notable commits: - 691a1439dd5aadf2c52b0cbdd3ebf0f3d4c6afbf: Sync proto versions and prepare build Python from source (as described in commit message). - 6ed048ab91d331a92d8ab635849e5646c49f8ff0: referenced in the commit message for the proto/version alignment effort. Impact: reduces risk of build-time and runtime issues, stabilizes CI pipelines, and ensures compatibility for ongoing development and releases. Technologies/skills demonstrated: Build system configuration, protobuf version management, cross-repo coordination, Python-from-source builds, repository: ydb-platform/ydb.
