Only the most important changes more recent than version 0.6 are noted here.
+Version 1.2.0:
+ Appending images to a WIM is now be done by default without re-building
+ the whole WIM. Use the --rebuild flag to get the old behavior (which
+ was to re-build the entire WIM when a new image is appended).
+
+ A new command `imagex optimize' is now available to manually re-build a
+ WIM that has wasted space due to repeated appends.
+
+ Progress information has been improved, and now arbitrary callback
+ functions can be used to show the progress of a WIM operation.
+
+ A possible bug with changing the bootable image of a WIM was fixed.
+
+ Some advisory locking is now done to prevent two processes from
+ modifying a WIM at the same time (but only in some cases). For example,
+ you cannot mount two images from a WIM read-write at the same time.
+
+ Some functions have been reorganized:
+ * wimlib_mount() renamed to wimlib_mount_image().
+ * wimlib_unmount() renamed to wimlib_unmount_image().
+ * wimlib_overwrite_xml_and_header() removed as
+ wimlib_overwrite() suffices now.
+ * wimlib_apply_image_to_ntfs_volume() removed as
+ wimlib_extract_image() suffices now.
+ * wimlib_add_image_from_ntfs_volume() removed as
+ * wimlib_add_image() suffices now.
+
+ Previously, the soname of libwim.so has been 0.0.0, despite many
+ interface changes. The soname is now updated to 1.0.0 and will now be
+ updated each release.
+
Version 1.1.0:
Resources will now be compressed using multiple threads by default.
(This applies to `imagex capture', `imagex append', and `imagex
