🤖 AI Changelog Review

This changelog does not fully meet the outlined criteria, so I will rewrite it to ensure clarity, precision, value for users, consistency, and avoidance of internal jargon.

Rewritten Changelog:

English: Added the ability to set a maximum limit for loop node iterations using environment variables. This allows users to prevent excessive or infinite loop cycles, ensuring better control and system stability.

Chinese: 新增功能：支持通过环境变量设置循环节点的最大循环次数。用户可通过此功能防止过多或无限循环，从而更好地控制系统稳定性。

Explanation of Changes:

1. Clear understanding: Original changelog mentions "support to limit" without clarifying why or how it benefits the user. The rewrite specifies the purpose (preventing excessive loops) and benefit (control and stability).
2. Precise wording: Original phrasing "maximum number of cycles for loop nodes" might cause confusion for some non-technical users. The rewritten version specifies "loop node iterations" and explains its practical implications.
3. Value clarity: Benefits for users (system stability and control) are explicitly highlighted.
4. Consistent format: Active voice and parallel structure are used consistently.
5. No internal jargon: "Environment variables" is common terminology for technical users, and other overly technical terms were avoided.
