     <li>[2022-11-30] :fire: PaddleSeg v2.7 is released! More details in <a href="https://github.com/PaddlePaddle/PaddleSeg/releases">Release Notes</a>.</li>
     <ul>
-        <li>Release <a href="./Matting/">PP-MattingV2</a>, a real-time human matting model with SOTA performance. Compared to previous models, the mean of error is reduced by 17.91%, the inference speed is improved by 44.6% on GPU. </li>
