October 2025: Delivered key power management and interoperability improvements for nRF54LM20A-based systems in the sdk-nrf repository, including RAM powerdown support with ram_pwrdn updates and conditional RAM bank handling to reduce active current draw. Extended Matter integration with the nRF7002 shield across nRF54LM20A variants, updating configurations and sample definitions to improve real-world deployment flexibility. Fixed critical boot and configuration issues: Openthread coprocessor USB workqueue boot crash resolved by aligning with the working CLI sample configuration; cleanup of overlays to simplify nRF54 board configurations. Documented and implemented BT RX stack overflow workaround for Matter lock samples on certain NUS configurations. These changes improve power efficiency, hardware interoperability, and overall reliability, while streamlining developer workflows. Key commits span ram_pwrdn, Matter configurations, and OpenThread/BT fixes.

September 2025 monthly summary for nrfconnect/sdk-nrf focused on documentation improvements for Matter provisioning and Thread support, consolidation of power consumption testing configuration, and maintenance cleanups that simplify OpenThread samples. Key enhancements include reorganizing Matter factory data content into .rst, clarifying factory data generation guidance, and updating the nRF54LM20 maturity/status in the Thread features table. Power testing configurations were integrated into main sample definitions (removing the dedicated power snippet), while bootloader stability for nRF54LM20 was addressed by switching from picolibc to the minimal C library. A maintenance cleanup removed an unused nRF54H20 OpenThread config to reduce confusion. Overall, these changes improve maintainability, onboarding speed, and reliability, aligning with Matter/Thread roadmaps and enabling faster, more confident releases.
