Only the most important changes more recent than version 0.6 are noted here.
+Version 1.5.2:
+ Added a new experimental LZX compressor which can be enabled by passing
+ '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
+ optimize'. (The latter is only applicable if the WIM is already
+ LZX-compressed and the '--recompress' option is also given.) The
+ experimental compressor is much slower but compresses the data slightly
+ more --- currently usually to within a fraction of a percent of the
+ results from WIMGAPI/ImageX.
+
+ A workaround has been added for compatibility with versions of WinPE
+ that interpret alternate data stream entries in the boot WIM
+ incorrectly.
+
+ An alignment bug that caused a crash in the LZX decompressor on some
+ builds was fixed.
+
+ wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
+ the WIM header when restoring the previous state of a WIM it failed to
+ successfully update.
+
+ Added a workaround to avoid an access denied error on Windows when
+ replacing a WIM file that another process has opened.
+
+Version 1.5.1:
+ wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
+ needed to be handled.
+
+ A bug in the interpretation of negative IMAGE indices in the
+ --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
+ `wimlib-imagex append' has been fixed.
+
+ A workaround has been added to successfully apply security descriptors
+ with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
+ 2013.1.13 or earlier.
+
+ `wimlib-imagex capture' can now accept the '--delta-from' option
+ multiple times.

Version 1.5.0:
Added support for "pipable" WIMs. Pipable WIMs allow capturing images
to standard output and applying images from standard input, but they are
more information.
To better support incremental backups, added support for declaring an
- image as a modified form of a prior image. See the documentation for
- the '--delta-from' option of `wimlib-imagex append'.
+ image as a modified form of another image. See the documentation for
+ the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
+ capture'.
+
+ Added supported for "delta" WIMs. See the documentation for the
+ '--delta-from' option of `wimlib-imagex capture'.
The library support for managing split WIMs has been changed to support
other arrangements, such as delta WIMs, and be easier to use. This
change is visible in `wimlib-imagex', which also can now accept the
- '--ref' option multiple times.
+ '--ref' option multiple times, and also now supports "delta" WIMs as
+ mentioned above.
wimlib now preserves WIM integrity tables by default, even if
WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
