Here, we report an improved measurement of D⁰–$$\bar{D}$$⁰ mixing and a search for CP violation in D⁰ decays to CP -even final states K⁺K^– and π⁺π^–. The measurement is based on the final Belle data sample of 976 fb^–1. The results are y_CP = (1.11 ± 0.22 ± 0.09)% and A_Γ = (–0.03 ± 0.20 ± 0.07)%, where the first uncertainty is statistical and the second is systematic.
