What changed
OpenClaw advanced its gateway-only extended-stable line to signed version 2026.8.35. The release adds GPT-6.1 Sol support and backports fixes for updates, recovery, delegated and cron completion, secret-store rotation, explicit cron allowlists, channel integrations, remote MCP startup and clean Windows llama.cpp startup.
Why it matters
The LTS-like line now supports a current model and closes more recovery, ownership and completion failures without requiring the newest feature train. Its breadth still makes a canary and rollback proof mandatory.
What to do
Verify the signed artifact, export gateway state, then canary from the exact deployed version. Test plugin preservation, duplicate-gateway prevention, delegated and cron completion, secret rotation, allowlists, remote MCP and managed llama.cpp startup before fleet promotion.
Caveat
The improvements are project-reported rather than independently audited. It remains gateway-only, not the latest feature line, and repeated large backport rollups increase regression and client compatibility risk.
