Claude Code v2.1.94 adds Bedrock Mantle, 60% faster writes

This update focuses on enterprise-readiness and core performance, making Claude Code a more viable tool for large-scale AWS-based development.

• –Bedrock Mantle support provides a high-performance, low-latency path for AWS enterprise users via the CLAUDE_CODE_USE_MANTLE environment variable.
• –60% faster file writes significantly reduce the friction of "waiting for AI" during large refactors and multi-file updates.
• –Increased default reasoning effort to "high" for professional tiers ensures more thorough analysis and fewer errors during complex tasks.
• –Enhanced MCP limits enable processing of significantly larger tool outputs, such as comprehensive logs or massive Slack thread histories.
• –Deprecated npm installation in favor of native platform scripts signals a move toward more robust, OS-specific distribution and version management.
