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). e.g. 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
+ export').
+
+ Some performance improvements in mounted WIMs.
+
+ More progress information is shown when capturing a WIM.
+
+Version 1.0.4:
+ Lots of minor fixes, code cleanups, and some documentation updates.
+ Nothing in particular is really noteworthy.
+
+Version 1.0.3:
+ LZX and XPRESS compression improvements.
+
+ Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
+ Link Bytes of the WIM.
+
+Version 1.0.2:
+ Fixed bug when capturing NTFS file with multiple named data streams.
+
+ Internally, we are now using inode structures, even though these don't
+ appear literally in the WIM file. This simplifies some of the code
+ (mainly for WIM mounting) and likely fixed a few problems, although it
+ needs more testing.
+
+Version 1.0.1:
+ Fixed problem when exporting images from XPRESS to LZX compressed WIM or
+ vice versa
+
Version 1.0.0:
Enough changes to call it version 1.0.0!
xattr or a Windows-style stream interface. Also they are supported when
capturing a WIM from NTFS or applying a WIM to NTFS.
+ Split WIMs are better supported. You may now apply an image directly
+ from a split WIM, mount an image from a split WIM read-only, or export
+ an image from a split WIM.
+
Using a capture configuration file is now supported (but not fully yet).
