-### Warning: This is SdFat Version 2.
+### Warning: Major Reformat of Source in 2.2.2
 
-Earlier releases of Version 1 are here:
+There are a huge number of changes in 2.2.2 since I decided to use clang-format
+to force Google style formatting.
 
-https://github.com/greiman/SdFat/releases
+I did this to avoid warnings from the static analysis programs Cppcheck and
+cpplint.
+
+clang-format is aggressive so it may actually cause code to fail.  For example
+clang-format rearranges the order of includes according to the selected style.
 
 UTF-8 encoded filenames are supported in v2.1.0 or later.
