我已经使用该newlfm软件包进行通信很多年了。最近，当我编写一封信时，我收到以下错误消息：
! Undefined control sequence.
\@zfancyhead ...1\hbox to\headwidth {\fancy@reset
\@zfancyvbox \headheight
{...
l.11 \begin{newlfm}
我不知道这个问题从何而来。我在 Mac 上使用最新的 TeX Live 安装，它是从 mactex.org 获得的。我没意识到自己做了什么改动，但这个问题似乎是在某个时候进行 MacTeX 更新以保持最新状态时出现的。
任何建议都将不胜感激。我有大量依赖于的通信基础newlfm！

该类似乎由于其某个依赖项的变化而被破坏（fancyhdr），即使采用从中得到的第一个示例也会textdoc newlfm出现同样的错误。
\documentclass[stdletter]{newlfm}

给出
