 Version 1.7.1-BETA:
-       Made more improvements to the compression algorithms.
+
+       Made a minor change to the LZMS compressor and decompressor to fix an
+       incompatibility with the Microsoft implementation.  In the unlikely
+       event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
+       earlier and a checksum error is reported when extracting files from it
+       with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
+       v1.7.1.
+
+       The performance of LZX compression in its default settings has been
+       improved by a further 5-10%.
 
        The default compression mode for wimcapture is now LZX compression in
        its default mode, which is the same as '--compress=maximum'.
