+## V1.0.0

+- Created this page to centralize documentation updates for NanoKVM Go / NanoKVM Go+.
+- Added the NetBird remote network guide, covering installation, enabling, SSO login, and external access; added Chinese and English screenshots and sidebar entries. The guide also notes that the integration currently uses NetBird Cloud only and does not enable LAN subnet routes or DNS.
+- Added Chinese and English Sipeed Remote Network disclaimer pages for direct access from the device QR code; the pages are URL-only, with Chinese and English screenshots and a ✓/✕ note.
