 # 印度占星 Skill 更新日志
 
+## 2026-10-23 — 完整数据版补上一年里的月返照和 Tithi
+
+- 当年和后两年各自列出月返照、原生 Patyayini 和 Tithi Pravesha。已有的年主、Muntha、Mudda、Sahams、Tajika 数值不改写。出生地八年总览会算；72 年的生命周期年返这一版先不做，避免一次生成几十张年返盘。
+- Skill 版本不变。
+
+## 2026-10-22 — 完整数据版标准大运表补上已有规则的子运
+
+- Narayana、Ashtottari、Yogini，以及已经按出处拆好子运的体系，标准大运表会列出子运。没有出处规则的体系写「本体系未提供子运」。Kalachakra 的子运和次小运标「简化模型」，主运仍是原来的星座年数。
+- Skill 版本不变。
+
 ## 2026-10-22 — 完整数据版写出 Jaimini Yogi 与 Ava Yogi 坐标
 
 - 这一节以前因为找不到计算模块，每张盘都是 blocked。现在用本命太阳、月亮黄经按 93°20′ 和 186°40′ 算出两点，中英附录各有一张表。空的 Tajika 候选改成一句「本年没有候选」；Goel 星座强度里没有落入行星时写「无」。
