This release introduces live streaming of foreground subagent tool calls and results to Remote Control clients, alongside new CLI commands for session management and detailed usage/cost metrics, including prompt cache and spend limits. Critical security patches address vulnerabilities related to unauthorized file access, plugin paths, and Bash command approvals.
