Only the most important changes more recent than version 0.6 are noted here.
+Version 1.6.0:
+ Support for extracting and updating the new version 3584 WIMs has been
+ added. These WIMs typically pack many streams ("files") together into a
+ single compressed resource, thereby saving space. This degrades the
+ performance of random access (such as that which occurs on a mounted
+ image), but optimizations have been implemented for extraction. These
+ new WIM files also typically use a new compression format (LZMS), which
+ is similar to LZMA and can offer a better compression ratio than LZX.
+ These new WIM files can be created with Dism using '/compress recovery',
+ or using `wimcapture' using '--pack-streams', although wimlib's LZMS
+ compressor is not yet very good, the latter is not recommended. Note:
+ this new WIM format is used by the Windows 8 web downloader, but
+ important segments of the raw '.esd' files are encrypted, so wimlib will
+ not be able to extract such files until they are first decrypted.
+
+ wimlib now supports extracting files and directories from a WIM image
+ based on a "listfile" that itself contains the list of paths to extract.
+ For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
+ and for the library itself, the new APIs are wimlib_extract_pathlist()
+ and wimlib_extract_paths(). Path globs containing wildcard characters
+ are supported.
+
+ For searching WIM files, wimlib now has configurable case sensitivity.
+ The default on Windows is still case-insensitive and the default on
+ UNIX-like systems is still case-sensitive, but this can be overwridden
+ on either platform through flags to wimlib_global_init(). For
+ `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
+ can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
+ respectively.
+
+ Support for compression chunk sizes greater than the default of 32768
+ bytes has been added. A larger chunk size typically results in a better
+ compression ratio. However, the MS implementation is seemingly not
+ compatible with all chunk sizes, especially for LZX compression, so the
+ defaults remain unchanged, with the exception of the new LZMS-compressed
+ WIMs, which use a larger chunk size by default.
+
+ The compression/decompression API exported by wimlib has been changed.
+ Now one set of functions handles all supported compression formats.
+
+ `wimcapture' and `wimappend' will now display the progress of scanning
+ the directory tree to capture, in addition to the progress of writing
+ data to the WIM. The '--verbose' option no longer does anything. The
+ library API change for this is the addition of several members to
+ `struct wimlib_progress_info_scan' available to progress callbacks.
+
+ `mkwinpeimg' now correctly handles the '--start-script' option when the
+ start script is not in the working directory.
+
+ Sequential extraction, previously requested by using
+ WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
+ WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
+ behavior (extract in file order).
+
+Version 1.5.3:
+ The new LZX compressor added in v1.5.2 has been improved and is now
+ enabled by default, except when `wimcapture' or `wimappend' is run
+ *without* the '--compress' option, in which case the faster LZX
+ compressor is used (the same as before). This behavior is reasonably
+ consistent with ImageX which actually uses "fast" (XPRESS) compression
+ by default. In those cases, use '--compress=maximum' to explicitly
+ capture a WIM image using the new (slower but better) LZX compressor.
+
+ The '--compress-slow' option still exists to `wimlib-imagex optimize',
+ but its new behavior is to tweak the new LZX compressor even more to
+ produce an even better compression ratio at the cost of more time spent
+ compressing.
+
+ `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
+ which recompresses the WIM file using the specified compression TYPE.
+ The new library API function used for this is
+ wimlib_set_output_compression_type().
+
+ Added the wimlib_get_xml_data() function to allow library clients to
+ easily retrieve the raw XML data from a WIM file if needed.
+
+ Fixed a bug that could cause an error code to be incorrectly returned
+ when writing XML data containing a <WINDOWS> element.
+
+ Mounted WIM images will now correctly show the default file stream even
+ if appears in the alternate data stream entries of the corresponding WIM
+ directory entry.
+
+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 related to the interpretation of the IMAGE in the
- --update-of=[WIMFILE:]IMAGE argument to `wimlib-imagex capture' and
+ 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
