 - CLI/Docs memory help accuracy: clarify `openclaw memory status --deep` behavior and align memory command examples/docs with the current search options. (#31803) Thanks @JasonOA888 and @Avi974.
 - Auto-reply/allowlist store account scoping: keep `/allowlist ... --store` writes scoped to the selected account and clear legacy unscoped entries when removing default-account store access, preventing cross-account default allowlist bleed-through from legacy pairing-store reads. Thanks @tdjackey for reporting and @vincentkoc for the fix.
 - Security/Nostr: harden profile mutation/import loopback guards by failing closed on non-loopback forwarded client headers (`x-forwarded-for` / `x-real-ip`) and rejecting `sec-fetch-site: cross-site`; adds regression coverage for proxy-forwarded and browser cross-site mutation attempts.
+- CLI/bootstrap Node version hint maintenance: replace hardcoded nvm `22` instructions in `openclaw.mjs` with `MIN_NODE_MAJOR` interpolation so future minimum-Node bumps keep startup guidance in sync automatically. (#39056) Thanks @onstash.
