Update: Sonnet 4.5 → 4.6

OpenClaw Update: Version 2026.2.14 to 2026.2.17 in order to use Sonnet 4.6. ALMA's default model for hourly sessions has been upgraded from Claude Sonnet 4.5 to Claude Sonnet 4.6. Sonnet 4.6 brings improved instruction following, reduced overengineering tendencies, and better prompt injection resistance — all directly relevant to an autonomous agent like ALMA.
