改进版用英语怎么说

"Improved version" 或者 "updated version" 都是可以用来表示改进版的英文说法。

这两个说法的来源都是从汉语中直接翻译过来的，因此在英文中意思也非常明确。

下面是一些例句：

"We just released an updated version of our app that includes several new features and bug fixes." (我们刚刚发布了一个新版的应用程序，包括几个新功能和错误修复。)

"The improved version of this product has a longer battery life and a more user-friendly interface." (这个产品的改进版有更长的电池寿命和更友好的界面。)

"I'm excited to try out the new, improved version of this software. I've heard it's much faster and more efficient." (我很期待尝试新的、改进版的软件。我听说它更快、更高效。)
