This PR appears to meet the basic NuttX requirements for a release notes update. Here's a breakdown:

Meets Requirements:

• Summary: Clearly states the purpose of the PR is to add release notes. The note about commit titles provides helpful context.
• Impact: Correctly identifies this as a "Release" impact, signifying a documentation update for a specific NuttX version.
• Testing: "CI" implies the PR will be validated through the Continuous Integration system, which is standard practice.

Potential Improvements (Based on Limited Information):

• Testing (Specificity): While "CI" is sufficient, providing more details about the specific CI checks relevant to release notes would be beneficial. This could include:
  • Confirmation that the release notes build correctly (e.g., format, links).
  • Mention any automated checks for completeness against the changelog or commit history.

Overall: This PR seems aligned with NuttX requirements. Adding more specifics about the CI testing would further strengthen it.

Hi @jerpelea: Sorry I believe nuttx/releases/12.7 (a537ecd) has major issues with RISC-V vork() and Signals. Here's my test log:

signest_test: Started interfere_main pid=52
[   55.182000] riscv_exception: EXCEPTION: Instruction page fault. MCAUSE: 000000000000000c, EPC: 0000000000000000, MTVAL: 0000000000000000
[   55.182000] riscv_exception: Segmentation fault in PID 52: ostest

We fixed the RISC-V issues recently. Could you add these to the 12.7 release? Thanks!

• riscv_fork.c: Fix vfork() for kernel mode + SMP #13633
• riscv: use g_running_task store current regs #13585

FYI nuttx/releases/12.7 (10e44f8) was tested successfully with QEMU RISC-V and OSTest for rv-virt:knsh64. Stress Test of rv-virt:knsh64 was also successful for 20 iterations. Thanks! 🎉

Update: Oops we're having build issues with a typo:

• {bp-13633} riscv_fork.c: Fix vfork() for kernel mode + SMP #13789 (comment)
• build.yml: Check out the correct branch of nuttx-apps #13806
