April 2026: Zephyr project (zephyrproject-rtos/zephyr). Focused on reliability and correct flash layout for the mdbt50q_cx_40_dongle. Delivered a critical fix to the Flash Partition Layout by correcting storage partition offset and size in Device Tree Source, preventing overlap with bootloader and ensuring proper flash usage. The patch aligns the node name and reg at 0xDC000 with size 0x4000, eliminating flash layout conflicts and reducing risk of boot issues in production.
