Release artifacts for all current and past NuttX releases can be downloaded at:
The Apache NuttX project uses Git SCM as its version control system.
There are two primary repositories:
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.
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. You can browse older messages at https://lists.apache.org/list.html?dev@nuttx.apache.org.
