Confirmation of whether it is a beta version

The Japanese documentation explicitly labels this library as a “Research Preview,” whereas the English documentation does not mention this.

• Japanese document: https://docs.anthropic.com/ja/docs/claude-code/overview
• English document: https://docs.anthropic.com/en/docs/claude-code/overview

Also, the release notes state that Claude Code has reached GA (General Availability).
Should we treat the current release as a beta / research-preview version?

Thank you for your clarification.
