-Note: as mentioned in the README, wimlib generally provides a slightly better
-XPRESS compression ratio than Microsoft's software, while it generally provides
-a slightly worse LZX compression ratio than Microsoft's software. So, you may
-not want to specify \fB--recompress\fR when optimizing a LZX-compressed WIM
-created on Windows.

+Note: as of wimlib v1.5.3, wimlib's LZX compressor usually achieves the same or
+better compression than Microsoft's, but is slightly slower.

+Spend even more time compressing the data in order to achieve a more optimal
+compression ratio. This only affects LZX-compressed WIM files. Compared to the
+default \fB--recompress\fR, this will make compression about twice as slow and
+will increase the compression ratio by maybe 1%, depending on the data.
