Month: 2026-05. Focused on delivering configurability, efficiency, and reliability improvements across Bluetooth HCI paths and NRFX, with impactful business value through reduced NVM usage, safer defaults, and extended device support. Summary highlights include Kconfig-driven feature gating, configurable RF path compensation, security-conscious command gating, and targeted NRFXLIB enhancements for experimental hardware and SoftDevice features.

March 2026 highlights for nrfconnect/sdk-nrfxlib: Implemented documentation linting and CI workflow setup (Vale-based linting, compliance checks, and CI pipelines) to improve maintainability and documentation quality. Introduced new BLE event structures and updated SoftDevice Controller to enhance connection management and advertising capabilities. Commits 4a7ea46f922608a914a81ad26360ddaf3f248d9e and af7c4d583d6fa8cf5bcb66564376786dc99cde74 underpin these changes, with CHANGELOG.rst updates.

February 2026 highlights a focused set of Bluetooth/BT controller improvements across Zephyr, the Zephyr SDK integration, and Nordic SDK libraries, delivering increased reliability, reduced memory footprint, and improved deployment flexibility for split-build configurations. The work spans public address configuration via HCI vendor-specific commands, controller size optimizations with library modularization and conditional compilation, compatibility and QoS enhancements, event handling simplifications, manifest synchronization, and isochronous scheduling support.

January 2026 monthly summary for sdk-nrfxlib: Delivered consolidated hardware support for nRF54LM, nRF54LV, and nRF54LS across MPSL, SoftDevice Controller (SDC), and the Front-End Module. Introduced separate libraries per SoC with experimental support for the nRF54LS device, Direct Test Mode integration, and enhanced build-time library selection to ensure the correct LM/LV/LS libraries are used for various SoC configurations. Coordinated library revs across MPSL and SDC to align with new per-SoC targets and improve build reliability.

March 2025: Stability-focused month for nrfconnect/sdk-nrfxlib, delivering two critical bug fixes that directly enhance reliability in initialization and multi-link operations, with updated changelogs and manifests to improve traceability across builds.
