    v0.4.2

    v0.4.2 完善水星与金星凌日搜索，支持地心看不到、但地表部分地区可见的掠凌，并更新相关地图与数据导出。

    主要变更

    • 优化凌日搜索，减少无效候选计算。
    • 增加地表掠凌判定、影轴 Gamma、半影半径及水星/金星周期族编号。
    • SVG、GeoJSON 和 KML 支持部分凌日可见区；正射图改为围绕可见区取景。
    • 更新中英文手册、示例图和回归测试。

    升级提示

    • 凌日查询现在包含地表可见事件。地心无接触时，HasExternal 为 false，地心接触时刻为空；使用 LocalTransit 查询当地接触，WindowStart / WindowEnd 仅表示求解窗口。

    v0.4.2

    v0.4.2 improves Mercury and Venus transit searches, including grazes that are invisible from Earth's centre but visible from some locations on its surface. It also updates transit maps and data exports.

    Highlights

    • Optimized transit searches to reduce unnecessary candidate calculations.
    • Added surface-graze detection, shadow-axis Gamma, penumbral radius, and transit-family numbers for Mercury and Venus.
    • Added partial-transit visibility regions to SVG, GeoJSON, and KML; orthographic maps now centre on the visible region.
    • Updated the bilingual manuals, example images, and regression tests.

    Upgrade Notes

    • Transit searches now include surface-visible events. When geocentric contacts are absent, HasExternal is false and geocentric contact times are zero. Use LocalTransit for local contacts; WindowStart and WindowEnd are search bounds, not contact times.
