present open source development in China from various dimensions. This year we set off again, combining data analysis tools and survey reports in various forms to draw a map of the Chinese open source scenarios ：以在线问卷方式搜集样本和数据，交叉对比法分析数据 Survey method: Online questionnaire to collect samples and data, cross-comparison method to analyze data 推广方法 ：线上社交媒体、博客、开源社、开源中国网站 Promotion method: Online social media, blogs 年的统计数据，并对比往年数据和其它一些公开发布的统计报告，我们有如下 一些重要发现： By analyzing the statistics for 2021 and comparing previous years' data with some other publicly released statistical reports, we have some significant findings as follows:

The technical explanation is that GIMP used to read the stream of ABR data byte by byte, and now it uses scanline reading instead. • PSD support improvements: PSD support improvements
