2 The library now permits making in-memory changes to a WIMStruct backed
3 by a read-only WIM file.
5 Extraction in "WIMBoot mode" without the WOF driver available no longer
6 fails if the disk containing the WIM file has too many partitions.
9 Made more improvements to the XPRESS, LZX, and LZMS compressors.
11 A number of improvements to the Windows port:
13 Fixes for setting short filenames.
15 Faster "WIMBoot" extraction.
17 Updated and slimmed down the dependent DLLs.
19 ACL inheritence bits are now restored.
21 Mandatory integrity labels are now backed up and restored.
23 Added a workaround for an issue where in rare cases, wimlib could create
24 a compressed data stream that could not be read correctly by Windows
25 after an extraction in "WIMBoot" mode.
28 Added file count progress data for
29 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
30 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
32 Added support for testing file exclusions via the user-provided
35 Some documentation improvements.
37 Made some clarifications to the license text in the COPYING file.
40 Made more improvements to the XPRESS, LZX, and LZMS compressors.
42 The default compression mode for wimcapture is now LZX compression in
43 its default mode, which is the same as '--compress=maximum'.
45 You can now specify an optional integer compression level to the
46 '--compress' option; e.g. '--compress=lzx:75'.
48 Made a minor change to the LZMS compressor and decompressor to fix an
49 incompatibility with the Microsoft implementation. In the unlikely
50 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
51 earlier and a checksum error is reported when extracting files from it
52 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
55 Added 'verify' subcommand to wimlib-imagex.
57 Notable library changes:
59 Custom compressor parameters have been removed from the library
60 in favor of the simpler level-based API.
62 Decompressor parameters have been removed entirely.
64 Library users can now specify a custom file for warning and
65 error messages to be sent to, rather than the default of
68 New progress messages:
69 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
70 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
72 New function: wimlib_verify_wim().
75 Improved compression, decompression, and extraction performance.
77 Improved compatibility with version 3584 WIM / ESD files:
78 - Add support for reading and writing multiple solid blocks per
79 archive, which WIMGAPI/DISM can create when appending an image.
80 - Correctly create solid blocks larger than 4 GiB.
82 'add' commands passed to wimupdate will now replace existing
83 nondirectory files by default. Use the --no-replace option to get the
86 The license for the library now contains an exception that allows using
87 it under the LGPL. See the COPYING file for details.
89 In reparse-point fixup mode (the default for capture), symbolic links
90 and junctions that point outside the tree being captured are no longer
91 excluded from capture.
93 Added support for "WIMBoot" capture and extraction. See the
94 documentation for the new '--wimboot' option to wimcapture and wimapply
97 On UNIX-like systems, you can now backup and restore device nodes, named
98 pipes, and sockets. In addition, 32-bit user and group IDs are now
101 The way that UNIX data is stored in WIM files has been changed. If you
102 captured any WIMs with the --unix-data option, to upgrade them you'll
103 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
104 re-capture them with --unix-data using this version.
106 wimlib now understands tagged metadata items, such as object IDs, that
107 can be stored in WIM directory entries.
109 Removed the --hardlink and --symlink options to wimapply, since I don't
110 think they are too useful and they got in the way of improving the code.
112 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
114 The 'mkwinpeimg' script now supports writing the ISO image to standard
117 The <ARCH> element in WIM XML data is now exported correctly.
119 On Windows, sparse file attributes are no longer set on extracted files.
120 Oddly enough, this actually saves disk space in some cases.
122 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
123 supported. Mounting WIM images now always requires extended attribute
124 support. Use --without-fuse to disable support for mounting WIM images;
125 this will also disable the need for extended attribute support.
127 Configuring with --enable-ssse3-sha1 now works correctly.
129 The shared library version has been bumped up. The main
130 incompatibilities are:
132 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
133 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
136 - User-provided progress functions are now registered using a
137 separate function, wimlib_register_progress_function(). The
138 'progress_func' argument to many functions no longer exists.
140 - The return value from user-provided progress functions is now
143 - A context argument has been added to the prototype of
144 user-provided progress functions.
146 - 'struct wimlib_capture_config' has been removed. The library
147 now takes the path to the configuration file directly. This
148 affects wimlib_add_image(), wimlib_add_image_multisource(),
149 and wimlib_update_image(). However, a NULL value passed in
150 the argument retains the same meaning.
152 - Removed deprecated functions: some (de)compression functions,
153 wimlib_extract_files(), and wimlib_print_metadata().
155 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
156 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
157 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
159 - Removed some progress messages:
160 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
161 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
162 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
165 - Removed some error codes. Numbering stays the same.
167 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
168 WIMLIB_UNMOUNT_FLAG_FORCE.
170 - WIM paths passed to progress functions now have a leading
174 Case-insensitive comparisons of strings (e.g. filenames) containing
175 UTF-16 codepoints above 32767 are now done correctly.
177 Fixed build failure on Mac OS X.
179 wimunmount now provides the '--new-image' option to cause changes to a
180 read-write mounted image to be committed as a new image rather than as
181 an update of the mounted image. (The corresponding new library flag is
182 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
184 The LZMS ("recovery") compression chunk size, or "dictionary size", may
185 now be up to 1 GiB (1,073,741,824 bytes).
187 The performance of LZX ("maximum") and LZMS ("recovery") compression
188 with large chunk sizes has been slightly improved.
191 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
192 decompressed correctly.
194 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
195 occurred in an unlikely case, and due to validity checks it did not
196 affect successfully created archives.
198 Fixed a minor compatibility issue with the LZMS compressor and
199 decompressor. This is *not* the default compression type and was only
200 introduced in v1.6.0. In the unlikely event that you created an
201 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
202 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
205 Memory usage for LZMS and LZX compression has been decreased.
207 wimextract now allows wildcard characters in paths specified on the
208 command line. Also, the '--strict-wildcards' option has been removed
209 and replaced with the inverse option '--nullglob'. See the
210 documentation for wimextract for more details and changes.
212 The wimlib_extract_files() function is now considered deprecated in
213 favor of wimlib_extract_paths().
215 Fixed more permissions problems when extracting files on Windows.
217 A new '--no-attributes' option has been added to wimapply and
218 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
220 The default chunk size is now set correctly when changing the
221 compression type of a WIM, for example with 'wimoptimize'.
223 The '--metadata' option to wiminfo has been replaced with the
224 '--detailed' option to wimdir.
226 In relevant wimlib-imagex commands, '--solid' may now be used as an
227 alias for '--pack-streams'.
230 Support for extracting and updating the new version 3584 WIMs has been
231 added. These WIMs typically pack many streams ("files") together into a
232 single compressed resource, thereby saving space. This degrades the
233 performance of random access (such as that which occurs on a mounted
234 image), but optimizations have been implemented for extraction. These
235 new WIM files also typically use a new compression format (LZMS), which
236 is similar to LZMA and can offer a better compression ratio than LZX.
237 These new WIM files can be created using `wimcapture' with
238 the '--compress=lzms --pack-streams' options. Note: this new WIM format
239 is used by the Windows 8 web downloader, but important segments of the
240 raw '.esd' files are encrypted, so wimlib will not be able to extract
241 such files until they are first decrypted.
243 wimlib now supports extracting files and directories from a WIM image
244 based on a "listfile" that itself contains the list of paths to extract.
245 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
246 and for the library itself, the new APIs are wimlib_extract_pathlist()
247 and wimlib_extract_paths(). Path globs containing wildcard characters
250 For searching WIM files, wimlib now has configurable case sensitivity.
251 The default on Windows is still case-insensitive and the default on
252 UNIX-like systems is still case-sensitive, but this can be overridden
253 on either platform through flags to wimlib_global_init(). For
254 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
255 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
258 Support for compression chunk sizes greater than the default of 32768
259 bytes has been added. A larger chunk size typically results in a better
260 compression ratio. However, the MS implementation is seemingly not
261 compatible with all chunk sizes, especially for LZX compression, so the
262 defaults remain unchanged, with the exception of the new LZMS-compressed
263 WIMs, which use a larger chunk size by default.
265 The compression/decompression API exported by wimlib has been changed.
266 Now one set of functions handles all supported compression formats.
268 `wimcapture' and `wimappend' will now display the progress of scanning
269 the directory tree to capture, in addition to the progress of writing
270 data to the WIM. The '--verbose' option no longer does anything. The
271 library API change for this is the addition of several members to
272 `struct wimlib_progress_info_scan' available to progress callbacks.
274 `mkwinpeimg' now correctly handles the '--start-script' option when the
275 start script is not in the working directory.
277 Sequential extraction, previously requested by using
278 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
279 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
280 behavior (extract in file order).
283 The new LZX compressor added in v1.5.2 has been improved and is now
284 enabled by default, except when `wimcapture' or `wimappend' is run
285 *without* the '--compress' option, in which case the faster LZX
286 compressor is used (the same as before). This behavior is reasonably
287 consistent with ImageX which actually uses "fast" (XPRESS) compression
288 by default. In those cases, use '--compress=maximum' to explicitly
289 capture a WIM image using the new (slower but better) LZX compressor.
291 The '--compress-slow' option still exists to `wimlib-imagex optimize',
292 but its new behavior is to tweak the new LZX compressor even more to
293 produce an even better compression ratio at the cost of more time spent
296 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
297 which recompresses the WIM file using the specified compression TYPE.
298 The new library API function used for this is
299 wimlib_set_output_compression_type().
301 Added the wimlib_get_xml_data() function to allow library clients to
302 easily retrieve the raw XML data from a WIM file if needed.
304 Fixed a bug that could cause an error code to be incorrectly returned
305 when writing XML data containing a <WINDOWS> element.
307 Mounted WIM images will now correctly show the default file stream even
308 if appears in the alternate data stream entries of the corresponding WIM
312 Added a new experimental LZX compressor which can be enabled by passing
313 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
314 optimize'. (The latter is only applicable if the WIM is already
315 LZX-compressed and the '--recompress' option is also given.) The
316 experimental compressor is much slower but compresses the data slightly
317 more --- currently usually to within a fraction of a percent of the
318 results from WIMGAPI/ImageX.
320 A workaround has been added for compatibility with versions of WinPE
321 that interpret alternate data stream entries in the boot WIM
324 An alignment bug that caused a crash in the LZX decompressor on some
327 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
328 the WIM header when restoring the previous state of a WIM it failed to
331 Added a workaround to avoid an access denied error on Windows when
332 replacing a WIM file that another process has opened.
335 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
336 needed to be handled.
338 A bug in the interpretation of negative IMAGE indices in the
339 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
340 `wimlib-imagex append' has been fixed.
342 A workaround has been added to successfully apply security descriptors
343 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
344 2013.1.13 or earlier.
346 `wimlib-imagex capture' can now accept the '--delta-from' option
350 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
351 to standard output and applying images from standard input, but they are
352 not compatible with Microsoft's software and are not created by default.
353 See the documentation for --pipable flag of `wimlib-imagex capture' for
356 To better support incremental backups, added support for declaring an
357 image as a modified form of another image. See the documentation for
358 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
361 Added supported for "delta" WIMs. See the documentation for the
362 '--delta-from' option of `wimlib-imagex capture'.
364 The library support for managing split WIMs has been changed to support
365 other arrangements, such as delta WIMs, and be easier to use. This
366 change is visible in `wimlib-imagex', which also can now accept the
367 '--ref' option multiple times, and also now supports "delta" WIMs as
370 wimlib now preserves WIM integrity tables by default, even if
371 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
372 behavior of `wimlib-imagex' whenever the WIM being operated on contains
373 an integrity table and the '--check' option is not specified.
375 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
376 (when --compress is not specified). This provides the best compression
377 ratio by default, which is usually what is desired, at a cost of some
380 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
381 is the command as in `wimlib-imagex COMMAND'; for example, it can be
382 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
383 appropriate hard links are created in UNIX installations of
384 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
385 batch files that emulate this behavior are generated.
387 Security descriptors are now extracted correctly on Windows.
389 Fixed archiving DOS names in NTFS-3g capture mode.
391 The extraction code has been rewritten and it will now be easier to
392 support new features on all supported backends (currently Win32, UNIX,
393 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
394 now supported on all backends, not just UNIX.
396 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
397 than the WAIK itself.
399 wimlib_global_init() now, by default, attempts to acquire additional
400 privileges on Windows, so library clients need not do this.
402 This update bumps the shared library version number up to 9, since it is
403 not binary compatibible with previous releases.
406 Fixed bug in `wimlib-imagex export' that made it impossible to export an
407 image from a WIM that is readonly at the filesystem level.
409 Return error code rather than segfaulting when trying to list files from
410 a non-first part of a split WIM.
412 Joining a WIM will now preserve the RP_FIX and READONLY flags.
415 On Windows, paths given to wimlib-imagex are now treated case
418 Improved behavior regarding invalid filenames; in particular, on
419 Windows, wimlib-imagex will, when extracting, now omit (with an option
420 to override this default) filenames differing only in case, or filenames
421 containing characters not valid on Windows.
423 On Windows, wimlib now supports capturing and extracting long paths
424 (longer than the so-called MAX_PATH).
426 On Windows, `wimlib-imagex update' now acquires proper privileges when
427 running as an Administrator.
429 `wimlib-imagex update' will now complain if no image is specified when
430 trying to update a multi-image WIM.
432 `wimlib-imagex update' now supports specifying a single update command
433 directly on the command line using the --command option.
435 wimlib-imagex will now choose different units for progress messages,
436 depending on the amount of data that needs to be processed.
438 `wimlib-imagex append' will now generate a unique WIM image name if no
439 name is specified and the defaulted name already exists in the WIM.
441 wimlib now allows you to create unnamed WIM images, which can then only
442 be referred to by index.
444 wimlib now allows you to explicitly declare you want write access to a
445 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
448 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
451 Progress callbacks have been added to wimlib's wimlib_update_image()
454 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
455 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
458 NTFS-3g capture now only warns about two conditions previously treated
461 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
464 wimlib now correctly detects and returns an error when reading a WIM
465 image with a cyclic directory structure. (Fun fact: such a WIM will
466 crash Microsoft's software.)
469 Added new "extract" and "update" subcommands to wimlib-imagex, along
470 with associated APIs in the library. These commands are intended mainly
471 for Windows use but can be used on UNIX as well.
473 Many documentation improvements.
475 Fixed a bug in the Windows build where relative symbolic links were not
476 captured in reparse-point fixup mode.
478 Fixed a bug in the Windows build where file handles were left open to
479 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
481 Fixed a bug in the Windows build of wimlib-imagex where globbing
482 split-WIM parts could cause the program to crash.
484 Fixed a bug where the creation time of WIM images would be shown instead
485 of the last modification time.
487 With the Windows build it is now possible to restore a WIM containing
488 symbolic links as a non-Administrator; however you will receive warnings
489 about not being able to extract the symbolic links.
492 Capturing a WIM image should now be significantly faster in most cases
493 due to improved use of the operating system's cache and avoiding reading
494 files twice whenever possible.
496 The Windows build should now work on Windows XP.
498 The Windows build now supports capturing and restoring hidden,
499 compressed, sparse, and encrypted files.
501 The Windows build now supports capturing and applying WIM images from
502 filesystems other than NTFS (with some reduced functionality).
504 The Windows build now extracts short names correctly.
506 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
507 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
508 capture' and `wimlib-imagex apply'.
510 The performance of splitting and joining WIMs should be slightly
513 The LZX and XPRESS compression and decompression functions are now
514 exported from the library.
517 Improvements and bugfixes for the Windows build.
519 Added --strict-acls options.
521 Fixed the way that wimlib determines the order of images in the WIM.
524 Since wimlib can now be used on Windows, wimlib's implementation of
525 ImageX has been renamed to wimlib-imagex to avoid confusion with
526 Microsoft's implementation of ImageX, which would have the same file
527 name ("imagex.exe"). If you really don't like this you can pass the
528 --with-imagex-progname option to `configure' to choose a different name,
529 or even simply rename the binary yourself (but the former way will
530 configure the man pages to use the chosen name).
532 Various bugs fixed in the Windows build. Mainly to do with capturing
533 and restoring alternate data streams correctly in weird cases, and
534 requesting the correct privileges when opening files. Also added the
535 --noacls options to wimlib-imagex capture, append, and apply.
537 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
538 dynamically loaded, so this may make the library compatible with Windows
539 XP (however, there may still be other problems).
542 Added experimental support for native Windows builds. Binaries can be
543 downloaded from the SourceForge page.
545 --source-list option added to `imagex capture' and `imagex append'.
547 Better support for different character encodings.
550 Storing UNIX file owners, groups, and modes in WIM images is now
551 possible using `imagex capture' with the --unix-data flag.
553 Minor bug fixes and documentation fixes.
556 NTFS capture: Fixed capturing duplicate reparse points.
558 NTFS capture: Capture first unnamed stream if there are more than one
559 (print warning instead of error).
561 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
564 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
567 Update to work with ntfs-3g version 2013.1.13.
570 Fixed truncating file to shorter but non-zero length on read-write
573 Various code cleanups and minor documentation fixes.
576 LZX and XPRESS decompression have received some additional optimizations
577 and should now be even faster. (Although, they were already pretty
578 fast--- much faster than typical I/O speeds.)
580 Fixed a bug introduced in v1.2.1 that would cause a directory tree
581 containing hard links to be captured incorrectly in some cases.
584 By default, unmounting a read-write mounted WIM with 'imagex unmount
585 --commit' will now change the WIM in-place without needing to write the
586 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
589 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
590 for a response from the daemon servicing the mounted WIM. Instead,
591 every second 'imagex unmount' will check if the daemon is still alive,
592 and keep waiting if so, otherwise terminate with an error.
594 'imagex unmount --commit' on a read-write mounted WIM will now print
595 progress information regarding the writing of new or modified streams
596 the WIM, just like when capturing or appending a WIM.
598 A small change has been made to XPRESS compression and it should improve
599 the compression ratio slightly.
601 A change was made that may improve performance slightly when applying a
602 WIM image to a NTFS volume.
604 Microsoft has managed to introduce even more bugs into their software,
605 and now the WIMs for Windows 8 have incorrect (too low) reference counts
606 for some streams. This is unsafe because such streams can be removed
607 when they are in actuality still referenced in the WIM (perhaps by a
608 different image). wimlib will now work around this problem by fixing
609 the stream reference counts. This is only done when wimlib_delete_image() is
610 called ('imagex delete') or when wimlib_mount_image() is called with
611 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
612 requires reading the metadata for all images in the WIM, so this will
613 make these operations noticably slower on WIMs with multiple images.
615 Various other bugfixes.
618 Appending images to a WIM is now be done by default without re-building
619 the whole WIM. Use the --rebuild flag to get the old behavior (which
620 was to re-build the entire WIM when a new image is appended).
622 A new command `imagex optimize' is now available to manually re-build a
623 WIM that has wasted space due to repeated appends.
625 Progress information has been improved, and now arbitrary callback
626 functions can be used to show the progress of a WIM operation.
628 A possible bug with changing the bootable image of a WIM was fixed.
630 Some advisory locking is now done to prevent two processes from
631 modifying a WIM at the same time (but only in some cases). For example,
632 you cannot mount two images from a WIM read-write at the same time.
634 Some functions have been reorganized:
635 * wimlib_mount() renamed to wimlib_mount_image().
636 * wimlib_unmount() renamed to wimlib_unmount_image().
637 * wimlib_overwrite_xml_and_header() removed as
638 wimlib_overwrite() suffices now.
639 * wimlib_apply_image_to_ntfs_volume() removed as
640 wimlib_extract_image() suffices now.
641 * wimlib_add_image_from_ntfs_volume() removed as
642 * wimlib_add_image() suffices now.
644 Previously, the soname of libwim.so has been 0.0.0, despite many
645 interface changes. The soname is now updated to 1.0.0 and will now be
646 updated each release.
649 Resources will now be compressed using multiple threads by default.

653 Some performance improvements in mounted WIMs.
655 More progress information is shown when capturing a WIM.
658 Lots of minor fixes, code cleanups, and some documentation updates.
659 Nothing in particular is really noteworthy.
662 LZX and XPRESS compression improvements.
664 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
665 Link Bytes of the WIM.
668 Fixed bug when capturing NTFS file with multiple named data streams.
670 Internally, we are now using inode structures, even though these don't
671 appear literally in the WIM file. This simplifies some of the code
672 (mainly for WIM mounting) and likely fixed a few problems, although it
676 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
680 Enough changes to call it version 1.0.0!
682 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
683 to a NTFS volume, is now supported.
685 Hard links and symbolic links have much improved support. They are
686 supported for WIM capture, WIM application, and mounted WIMs (you can
687 even make them on read-write mounted WIMs).
689 Alternate data streams are now supported on mounted WIMs through an
690 xattr or a Windows-style stream interface. Also they are supported when
691 capturing a WIM from NTFS or applying a WIM to NTFS.
693 Split WIMs are better supported. You may now apply an image directly
694 from a split WIM, mount an image from a split WIM read-only, or export
695 an image from a split WIM.
697 Using a capture configuration file is now supported (but not fully yet).
699 SHA1 message digests are checked in more places, so we can make sure
700 applied and captured data is correct.
702 Man pages have been updated and consolidated.
705 Fixed segfault when unmounting read-only WIM.
708 Support for joining and splitting WIMs.
709 Also, security data is now preserved by default.
712 Can now build with older gcc and system headers, like on CentOS 5.
715 Fixed bug that made it impossible to overwrite files in read-write
