February 2026 monthly summary for repository renesas/zephyr: Stability and bug-fix focus with no new features released. Delivered a critical GPIO interrupt IRQ override bug fix to ensure IRQ configurations are not overridden when a GPIO pin interrupt is disabled and subsequently re-enabled. This improves runtime reliability of GPIO interrupt handling and reduces risk of regression when reconfiguring interrupts.

2025-09 monthly summary for zephyrproject-rtos/zephyr-testing. Focused on stabilizing asynchronous ADC reads and delivering targeted reliability improvements in the AD559x/AD599x driver path. Key work delivered a fix to the async read logic to correctly handle cases with NULL async signals by also verifying that a callback is set, aligning behavior with official ADC docs and preventing driver breakdown when no explicit async signal is provided. The change improves reliability of ADC reads across all channels and reduces potential race conditions during asynchronous conversions. Overall, the month delivered improved system robustness in the ADC subsystem with minimal footprint and clear developer-focused commit messaging.
