Only the most important changes more recent than version 0.6 are noted here.
+Version 1.6.2:
+ Case-insensitive comparisons of strings (e.g. filenames) containing
+ UTF-16 codepoints above 32767 are now done correctly.
+
+ Fixed build failure on Mac OS X.
+
+ wimunmount now provides the '--new-image' option to cause changes to a
+ read-write mounted image to be committed as a new image rather than as
+ an update of the mounted image. (The corresponding new library flag is
+ WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
+
+ The LZMS ("recovery") compression chunk size, or "dictionary size", may
+ now be up to 1 GiB (1,073,741,824 bytes).
+
+ The performance of LZX ("maximum") and LZMS ("recovery") compression
+ with large chunk sizes has been slightly improved.
+
Version 1.6.1:
Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
decompressed correctly.
