Compatibility Concerns
* [#8827](https://github.com/apache/nuttx/pull/8827) arch/nrf52: nvmc and flash should depends on ALLOW_BSD_COMPONENTS=y  
Users using nvmc and flash must allow BSD components (CONFIG_ALLOW_BSD_COMPONENTS=y).
* [#8992](https://github.com/apache/nuttx/pull/8992) stm32: Remove GPIO_{SPEED|MODE}_xxx and provide a legacy path for lazy migration  
All boards board.h should be migrated using tools/stm32_pinmap_tool.py
`tools/stm32_pinmap_tool.py --pinmap arch/arm/src/stm32h7/hardware/stm32h7x3xx_pinmap_legacy.h --addall --suffix _0 --report /include/board.h
it will output 2 sections that should be used to update the board.h.
* [#9527](https://github.com/apache/nuttx/pull/9527) sched/tls: remove PTHREAD_CLEANUP from Kconfig  
use PTHREAD_CLEANUP_STACKSIZE to enable or disable interfaces pthread_cleanup_push() and pthread_cleanup_pop().
Same as TLS_TASK_NELEM - It is no need to use two variables. Make the reserved entries more explicit
* [#8985](https://github.com/apache/nuttx/pull/8985) drivers/pipe: make pipe and named pipe (mkfifo) POSIX-compliant (blocking open)  
It would be a possible breaking change if any application was written specifically to expect an open for write-only 
(and O_NONBLOCK cleared, of course) to be non-blocking even if there are no readers.
Being able to port POSIX-compliant applications that expect open to block when opening for write-only with no readers
would enhance NuttX's objective of "to achieve a high degree of standards compliance. The primary governing standards 
are POSIX and ANSI standards". That is the case for RTP Tools, for instance.
