+Compatibility Concerns
+* [#18083](https://github.com/apache/nuttx/pull/18083) !sched: Fix MISRA-C
violations
+This pull request consists of a series of commits primarily focused on
improving code quality, enhancing type safety, addressing
+ compilation warnings, and ensuring compliance with MISRA-C coding standards
across various subsystems of the NuttX operating system.
+Impact
+ Users (Application Developers): The changes are largely internal and
should not affect the functional behavior or the public
+ POSIX API for applications (e.g., timer_create, sem_wait, clock_gettime).
The primary user-facing impact is increased code
+ reliability and stability due to stricter type checking and error handling.
+ Code Quality and Maintenance: By addressing MISRA-C violations and
eliminating compiler warnings, the codebase becomes more portable,
+ predictable, and easier to maintain. The refactoring in the timer
subsystem (removing early returns, simplifying logic) improves
+ readability and reduces the risk of latent bugs.
+ Compatibility: The modifications maintain backward source compatibility.
However, developers who directly relied on the internal
+ nxclock_settime() symbol will need to adapt, as it has been removed.
+ Documentation: No direct impact on external documentation. The inline
comments within the code are updated to reflect some of the logic changes.
+ Security: While not a direct security patch, the overall hardening (e.g.,
stricter input validation) contributes to the system's
+ robustness against potential misuse.
+
+* [#18398](https://github.com/apache/nuttx/pull/18398) !boards: Align naming
of Kconfig options for interpreters
+Aligns the Kconfig option naming for interpreters. Part of twin PR
apache/nuttx-apps#3403 which should be merged first.
+
+BREAKING CHANGE:
+ All configurations using CONFIG_INTERPRETER_* options will no longer
compile due to missing symbol errors.
+ The fix is very quick: any configurations using this options should add a
trailing S following INTERPRETER in the affected Kconfig variables.
+ I believe ./tools/refresh.sh should also be capable of doing this
automatically.
