What's New in Lu Ban Ruler
1.7
October 16, 2026
This update fixes a drawing issue on the ruler strip. FIXED • Where two neighbouring sections were both Good (or both Bad), the line between them was missing and they looked like a single long cell: Righteousness next to Official, Illness next to Separation, or the point where the ruler starts a new cycle (Foundation next to Wealth). Every section boundary is now ruled, just like the sub-sections, on all four rulers - Clear Opening, Yang Dwelling, Yin Dwelling and Classic Luban - and in all three languages. Measurements, the section you land in and the Good/Bad result are unchanged. IMPROVED • The screenshots in the User Guide were retaken so they match the ruler on screen.
