Claude Code 2.1.316 lets you set subagent effort and announces the end of Opus 4.8 fast mode
Claude Code version 2.1.316 brings the CLAUDE_CODE_SUBAGENT_EFFORT variable, so that subagents run at their own effort level instead of inheriting the session's, and an option to disable the ultrathink keyword. In the enterprise gateway, monthly budgets shared per group and layered policies are added. Opus 4.8 fast mode was deprecated on 10/30 and will be removed on 11/30: after that, requests return an error, without falling back to normal mode, and Anthropic recommends migrating to Opus 5.5.
