February 2026 — SDK-nrf monthly summary: Delivered a targeted API configurability enhancement for the MPSL FEM API to allow optional FEM linking, decoupling FEM code from applications that do not require FEM functionality. This improves modularity, reduces dependencies, and enables leaner builds. No major bug fixes were recorded this month; the focus was on API design, maintainability, and cross-repo impact within nrfconnect/sdk-nrf. Overall impact: greater flexibility for customers integrating MPSL FEM features, faster build times, and easier onboarding for projects utilizing minimal FEM capabilities. Technologies demonstrated: API configurability design, feature flag-like configuration, and robust commit hygiene across the repository.

January 2026 (2026-01) monthly summary for nrfconnect/sdk-nrf focused on delivering an API flexibility improvement in Bluetooth controller handling. Implemented a user-overridable bt_ctlr_assert_handle via a weak symbol, enabling users to provide their own implementation without the need to wrap, increasing portability across toolchains and reducing integration friction. No major bugs fixed this month in the repository. The change is accompanied by targeted commit work in the ipc_radio area to propagate the weak symbol usage.
