+### Build Procedure Change for Auto Tools
+
+You can ignore this if you are using CMake or one of the win32 build
+methods.
+
+As of release 2.10.32 the release archive file will no longer contain
+the result of running `autoreconf`. This places a new requirement on
+the target platform, that `autoreconf` and friends are installed. This
+should not be an issue for most users. If it is, you can roll your own
+auto-tooled version by untarring the distribution and running
+`autoreconf` in its root directory as follows:
+
+```sh
+autoreconf -if
+./configure --enable-freedist --enable-as-02
+make
+make dist
+```
