目前我正在学习langchain 1.0 和langchain 0.3的框架变化的情况。在阅读本次更新的过程中，发现这一次的官方文档的编排真的是太赞了，这让我这种刚刚进入 LLM应用开发的新人感觉到非常的舒适，也是十分感谢你们公司团队为此做出的巨大努力。
在学习这次langchain 1.0文档的时候，发现对langchain 家族包有一些调整。原来的langchain_community 包似乎是要被langchain_classic包替代，可是其中涉及到Document loader 并没有在langchain_classic中涉及，这让我感到十分的疑惑。

@mdrxy commented on GitHub (Nov 3, 2025):

langchain-community will continue to exist; I think where you may be confused is that langchain-classic (formerly langchain modules) performs re-exports from langchain-community

Which Document Loader are you looking for? Here's the list of what's available in classic
