Compatibility Concerns
| Markdown |
|---|
* [#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. |

How to Clone the Git Repository
The Apache NuttX project uses Git SCM as its version control system.
There are two primary repositories:
- nuttx - The real time operating system itself.
- apps - Optional applications and example programs for the operating system. You can use this repository or make your own custom one.
The main "Single Source of Truth" repositories are hosted by the ASF:
These are synchronized with repositories hosted at GitHub:
The main forum for project communication, to ask a question, get involved, or contribute to NuttX, is our mailing list, dev@nuttx.apache.org. The list is publicly archived and searchable at https://lists.apache.org/list.html?dev@nuttx.apache.org. For more information, see NuttX Community.
Enthusiastic Contributors Welcome!
NuttX is a free open-source project. If you'd like to participate, whether it's to enhance documentation (even these release notes) or dive into the nitty gritty of some low-level drivers, please join us! You can join the conversation at our dev mailing list by emailing dev-subscribe@nuttx.apache.org. The mailing list is open to the public and archived.
