+Version 1.8.4-BETA:
+       Fixed a bug where, on Windows, wimlib would change the security
+       descriptor of the target directory of an extraction even when the
+       '--no-acls' option was specified.
+
+       Added experimental support for Windows VSS (Volume Shadow Copy Service).
+       The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
+       create and use a temporary VSS snapshot when capturing a WIM image.
+
+       Added a new '--image-property' option to 'wimcapture', 'wimappend', and
+       'wiminfo'.  This option lets you assign values to elements in a WIM
+       file's XML document by name.
+
+       The wimlib_get_image_property() and wimlib_set_image_property() API
+       functions now support numerically indexed elements.

        wimlib_get_image_property() and wimlib_set_image_property().
 

+       Added support for (unsafe) in-place compaction of WIM files.
+
+       Improved performance of image export by reusing metadata resources
+       instead of always rebuilding and recompressing them.
+
+       Improved performance of wimlib_update_image() by delaying the update to
+       the WIM's XML document until a write is requested.
+
+       On Windows, the target of an extraction may now be a reparse point
+       (which will be dereferenced).
+
+       On Windows, wimlib now correctly restores non-Microsoft reparse points.
+       However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
+
+       On Windows, wimlib now has improved performance when archiving files
+       from a filesystem backed by a WIM (a "WIMBoot" setup).
