Claude Code v2.1.198 brings Chrome-based Claude to all users. New background Agent notifications use the Notification hook when an Agent session requires input or completes. The /dataviz skill offers chart/dashboard design guidance and a runnable color palette validator. The Gateway adds Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses automatically advance the failover chain. Background Agents now automatically commit, push, and open draft PRs after completing code work without interruption. Built-in Explore Agent inherits the main session model (up to Opus); sub-agents and context compression inherit the session's extended thinking configuration. Various fixes address brief network interruptions, excessive background classifier requests, and task panel stuck in 'Running' state.
