February 2026 monthly summary focused on iOS deployment target readiness across Buck2 and Buck2 Prelude. Key features delivered include adding iOS 17.2 to TARGET_SDK_VERSIONS in both repositories to enable deployment target constraints for a future migration. This work serves as a no-op prerequisite for the iOS 17.2 migration, supports the upcoming CI validation build, and enables the eventual FWA_IOS_VERSION bump in v278 (planned ~April). Major bugs fixed: none reported this period. Overall impact: establishes cross-repo readiness for iOS 17.2 migration, reduces migration risk, and aligns with release schedules; enables smoother upgrade paths for downstream projects relying on Buck2. Technologies/skills demonstrated: cross-repo collaboration, deployment target management, clear commit documentation, and migration planning with forward-looking CI validation and release readiness.
