3 Made a minor change to the LZMS compressor and decompressor to fix an
4 incompatibility with the Microsoft implementation. In the unlikely
5 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
6 earlier and a checksum error is reported when extracting files from it
7 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
10 The performance of LZX compression in its default settings has been
11 improved by a further 5-10%.
13 The default compression mode for wimcapture is now LZX compression in
14 its default mode, which is the same as '--compress=maximum'.
16 You can now specify an optional integer compression level to the
17 '--compress' or '--solid-compress' options; e.g. '--compress=lzx:75'.
18 Currently, the default level in all cases is 50. This capability
19 deprecates the '--compress-slow' (or '--recompress-slow') option to
20 several wimlib-imagex commands.
22 The '--pack-streams', '--pack-compress', and '--pack-chunk-size' options
23 to several wimlib-imagex commands have been deprecated in favor of more
24 "standard" names: '--solid', '--solid-compress', and
25 '--solid-chunk-size', respectively.
27 The XPRESS compressor no longer supports chunks larger than 65536 bytes.
28 There is little point in having larger chunks, since the LZ77 sliding
29 window for XPRESS cannot be larger than 65536 bytes. This change does
30 not affect the default XPRESS chunk size, which is 32768.
32 The new (as of v1.7.0) extraction code will no longer run out of file
33 handles when extracting many (1000+) identical files.
37 Custom compressor parameters have been removed from the library
38 in favor of the simpler level-based API.
40 Decompressor parameters have been removed entirely.
42 The maximum XPRESS chunk size has been reduced, as mentioned
45 Library users can now initialize and de-initialize the library
46 multiple times in one run of an application program.
48 Library users will now receive WIMLIB_PROGRESS_MSG_WRITE_STREAMS
49 and WIMLIB_PROGRESS_MSG_EXTRACT_STREAMS messages more frequently
50 when writing or extracting large WIM files.
52 Added experimental new write flag:
53 WIMLIB_WRITE_FLAG_SEND_DONE_WITH_FILE_MESSAGES.
55 Library users can now specify a custom file for warning and
56 error messages to be sent to, rather than the default of
60 Improved compression, decompression, and extraction performance.
62 Improved compatibility with version 3584 WIM / ESD files:
63 - Add support for reading and writing multiple solid blocks per
64 archive, which WIMGAPI/DISM can create when appending an image.
65 - Correctly create solid blocks larger than 4 GiB.
67 'add' commands passed to wimupdate will now replace existing
68 nondirectory files by default. Use the --no-replace option to get the
71 The license for the library now contains an exception that allows using
72 it under the LGPL. See the COPYING file for details.
74 In reparse-point fixup mode (the default for capture), symbolic links
75 and junctions that point outside the tree being captured are no longer
76 excluded from capture.
78 Added support for "WIMBoot" capture and extraction. See the
79 documentation for the new '--wimboot' option to wimcapture and wimapply
82 On UNIX-like systems, you can now backup and restore device nodes, named
83 pipes, and sockets. In addition, 32-bit user and group IDs are now
86 The way that UNIX data is stored in WIM files has been changed. If you
87 captured any WIMs with the --unix-data option, to upgrade them you'll
88 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
89 re-capture them with --unix-data using this version.
91 wimlib now understands tagged metadata items, such as object IDs, that
92 can be stored in WIM directory entries.
94 Removed the --hardlink and --symlink options to wimapply, since I don't
95 think they are too useful and they got in the way of improving the code.
97 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
99 The 'mkwinpeimg' script now supports writing the ISO image to standard
102 The <ARCH> element in WIM XML data is now exported correctly.
104 On Windows, sparse file attributes are no longer set on extracted files.
105 Oddly enough, this actually saves disk space in some cases.
107 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
108 supported. Mounting WIM images now always requires extended attribute
109 support. Use --without-fuse to disable support for mounting WIM images;
110 this will also disable the need for extended attribute support.
112 Configuring with --enable-ssse3-sha1 now works correctly.
114 The shared library version has been bumped up. The main
115 incompatibilities are:
117 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
118 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
121 - User-provided progress functions are now registered using a
122 separate function, wimlib_register_progress_function(). The
123 'progress_func' argument to many functions no longer exists.
125 - The return value from user-provided progress functions is now
128 - A context argument has been added to the prototype of
129 user-provided progress functions.
131 - 'struct wimlib_capture_config' has been removed. The library
132 now takes the path to the configuration file directly. This
133 affects wimlib_add_image(), wimlib_add_image_multisource(),
134 and wimlib_update_image(). However, a NULL value passed in
135 the argument retains the same meaning.
137 - Removed deprecated functions: some (de)compression functions,
138 wimlib_extract_files(), and wimlib_print_metadata().
140 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
141 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
142 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
144 - Removed some progress messages:
145 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
146 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
147 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
150 - Removed some error codes. Numbering stays the same.
152 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
153 WIMLIB_UNMOUNT_FLAG_FORCE.
155 - WIM paths passed to progress functions now have a leading
159 Case-insensitive comparisons of strings (e.g. filenames) containing
160 UTF-16 codepoints above 32767 are now done correctly.
162 Fixed build failure on Mac OS X.
164 wimunmount now provides the '--new-image' option to cause changes to a
165 read-write mounted image to be committed as a new image rather than as
166 an update of the mounted image. (The corresponding new library flag is
167 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
169 The LZMS ("recovery") compression chunk size, or "dictionary size", may
170 now be up to 1 GiB (1,073,741,824 bytes).
172 The performance of LZX ("maximum") and LZMS ("recovery") compression
173 with large chunk sizes has been slightly improved.
176 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
177 decompressed correctly.
179 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
180 occurred in an unlikely case, and due to validity checks it did not
181 affect successfully created archives.
183 Fixed a minor compatibility issue with the LZMS compressor and
184 decompressor. This is *not* the default compression type and was only
185 introduced in v1.6.0. In the unlikely event that you created an
186 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
187 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
190 Memory usage for LZMS and LZX compression has been decreased.
192 wimextract now allows wildcard characters in paths specified on the
193 command line. Also, the '--strict-wildcards' option has been removed
194 and replaced with the inverse option '--nullglob'. See the
195 documentation for wimextract for more details and changes.
197 The wimlib_extract_files() function is now considered deprecated in
198 favor of wimlib_extract_paths().
200 Fixed more permissions problems when extracting files on Windows.
202 A new '--no-attributes' option has been added to wimapply and
203 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
205 The default chunk size is now set correctly when changing the
206 compression type of a WIM, for example with 'wimoptimize'.
208 The '--metadata' option to wiminfo has been replaced with the
209 '--detailed' option to wimdir.
211 In relevant wimlib-imagex commands, '--solid' may now be used as an
212 alias for '--pack-streams'.
215 Support for extracting and updating the new version 3584 WIMs has been
216 added. These WIMs typically pack many streams ("files") together into a
217 single compressed resource, thereby saving space. This degrades the
218 performance of random access (such as that which occurs on a mounted
219 image), but optimizations have been implemented for extraction. These
220 new WIM files also typically use a new compression format (LZMS), which
221 is similar to LZMA and can offer a better compression ratio than LZX.
222 These new WIM files can be created using `wimcapture' with
223 the '--compress=lzms --pack-streams' options. Note: this new WIM format
224 is used by the Windows 8 web downloader, but important segments of the
225 raw '.esd' files are encrypted, so wimlib will not be able to extract
226 such files until they are first decrypted.
228 wimlib now supports extracting files and directories from a WIM image
229 based on a "listfile" that itself contains the list of paths to extract.
230 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
231 and for the library itself, the new APIs are wimlib_extract_pathlist()
232 and wimlib_extract_paths(). Path globs containing wildcard characters
235 For searching WIM files, wimlib now has configurable case sensitivity.
236 The default on Windows is still case-insensitive and the default on
237 UNIX-like systems is still case-sensitive, but this can be overridden
238 on either platform through flags to wimlib_global_init(). For
239 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
240 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
243 Support for compression chunk sizes greater than the default of 32768
244 bytes has been added. A larger chunk size typically results in a better
245 compression ratio. However, the MS implementation is seemingly not
246 compatible with all chunk sizes, especially for LZX compression, so the
247 defaults remain unchanged, with the exception of the new LZMS-compressed
248 WIMs, which use a larger chunk size by default.
250 The compression/decompression API exported by wimlib has been changed.
251 Now one set of functions handles all supported compression formats.
253 `wimcapture' and `wimappend' will now display the progress of scanning
254 the directory tree to capture, in addition to the progress of writing
255 data to the WIM. The '--verbose' option no longer does anything. The
256 library API change for this is the addition of several members to
257 `struct wimlib_progress_info_scan' available to progress callbacks.
259 `mkwinpeimg' now correctly handles the '--start-script' option when the
260 start script is not in the working directory.
262 Sequential extraction, previously requested by using
263 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
264 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
265 behavior (extract in file order).
268 The new LZX compressor added in v1.5.2 has been improved and is now
269 enabled by default, except when `wimcapture' or `wimappend' is run
270 *without* the '--compress' option, in which case the faster LZX
271 compressor is used (the same as before). This behavior is reasonably
272 consistent with ImageX which actually uses "fast" (XPRESS) compression
273 by default. In those cases, use '--compress=maximum' to explicitly
274 capture a WIM image using the new (slower but better) LZX compressor.
276 The '--compress-slow' option still exists to `wimlib-imagex optimize',
277 but its new behavior is to tweak the new LZX compressor even more to
278 produce an even better compression ratio at the cost of more time spent
281 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
282 which recompresses the WIM file using the specified compression TYPE.
283 The new library API function used for this is
284 wimlib_set_output_compression_type().
286 Added the wimlib_get_xml_data() function to allow library clients to
287 easily retrieve the raw XML data from a WIM file if needed.
289 Fixed a bug that could cause an error code to be incorrectly returned
290 when writing XML data containing a <WINDOWS> element.
292 Mounted WIM images will now correctly show the default file stream even
293 if appears in the alternate data stream entries of the corresponding WIM
297 Added a new experimental LZX compressor which can be enabled by passing
298 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
299 optimize'. (The latter is only applicable if the WIM is already
300 LZX-compressed and the '--recompress' option is also given.) The
301 experimental compressor is much slower but compresses the data slightly
302 more --- currently usually to within a fraction of a percent of the
303 results from WIMGAPI/ImageX.
305 A workaround has been added for compatibility with versions of WinPE
306 that interpret alternate data stream entries in the boot WIM
309 An alignment bug that caused a crash in the LZX decompressor on some
312 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
313 the WIM header when restoring the previous state of a WIM it failed to
316 Added a workaround to avoid an access denied error on Windows when
317 replacing a WIM file that another process has opened.
320 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
321 needed to be handled.
323 A bug in the interpretation of negative IMAGE indices in the
324 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
325 `wimlib-imagex append' has been fixed.
327 A workaround has been added to successfully apply security descriptors
328 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
329 2013.1.13 or earlier.
331 `wimlib-imagex capture' can now accept the '--delta-from' option
335 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
336 to standard output and applying images from standard input, but they are
337 not compatible with Microsoft's software and are not created by default.
338 See the documentation for --pipable flag of `wimlib-imagex capture' for
341 To better support incremental backups, added support for declaring an
342 image as a modified form of another image. See the documentation for
343 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
346 Added supported for "delta" WIMs. See the documentation for the
347 '--delta-from' option of `wimlib-imagex capture'.
349 The library support for managing split WIMs has been changed to support
350 other arrangements, such as delta WIMs, and be easier to use. This
351 change is visible in `wimlib-imagex', which also can now accept the
352 '--ref' option multiple times, and also now supports "delta" WIMs as
355 wimlib now preserves WIM integrity tables by default, even if
356 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
357 behavior of `wimlib-imagex' whenever the WIM being operated on contains
358 an integrity table and the '--check' option is not specified.
360 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
361 (when --compress is not specified). This provides the best compression
362 ratio by default, which is usually what is desired, at a cost of some
365 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
366 is the command as in `wimlib-imagex COMMAND'; for example, it can be
367 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
368 appropriate hard links are created in UNIX installations of
369 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
370 batch files that emulate this behavior are generated.
372 Security descriptors are now extracted correctly on Windows.
374 Fixed archiving DOS names in NTFS-3g capture mode.
376 The extraction code has been rewritten and it will now be easier to
377 support new features on all supported backends (currently Win32, UNIX,
378 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
379 now supported on all backends, not just UNIX.
381 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
382 than the WAIK itself.
384 wimlib_global_init() now, by default, attempts to acquire additional
385 privileges on Windows, so library clients need not do this.
387 This update bumps the shared library version number up to 9, since it is
388 not binary compatibible with previous releases.
391 Fixed bug in `wimlib-imagex export' that made it impossible to export an
392 image from a WIM that is readonly at the filesystem level.
394 Return error code rather than segfaulting when trying to list files from
395 a non-first part of a split WIM.
397 Joining a WIM will now preserve the RP_FIX and READONLY flags.
400 On Windows, paths given to wimlib-imagex are now treated case
403 Improved behavior regarding invalid filenames; in particular, on
404 Windows, wimlib-imagex will, when extracting, now omit (with an option
405 to override this default) filenames differing only in case, or filenames
406 containing characters not valid on Windows.
408 On Windows, wimlib now supports capturing and extracting long paths
409 (longer than the so-called MAX_PATH).
411 On Windows, `wimlib-imagex update' now acquires proper privileges when
412 running as an Administrator.
414 `wimlib-imagex update' will now complain if no image is specified when
415 trying to update a multi-image WIM.
417 `wimlib-imagex update' now supports specifying a single update command
418 directly on the command line using the --command option.
420 wimlib-imagex will now choose different units for progress messages,
421 depending on the amount of data that needs to be processed.
423 `wimlib-imagex append' will now generate a unique WIM image name if no
424 name is specified and the defaulted name already exists in the WIM.
426 wimlib now allows you to create unnamed WIM images, which can then only
427 be referred to by index.
429 wimlib now allows you to explicitly declare you want write access to a
430 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
433 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
436 Progress callbacks have been added to wimlib's wimlib_update_image()
439 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
440 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
443 NTFS-3g capture now only warns about two conditions previously treated
446 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
449 wimlib now correctly detects and returns an error when reading a WIM
450 image with a cyclic directory structure. (Fun fact: such a WIM will
451 crash Microsoft's software.)
454 Added new "extract" and "update" subcommands to wimlib-imagex, along
455 with associated APIs in the library. These commands are intended mainly
456 for Windows use but can be used on UNIX as well.
458 Many documentation improvements.
460 Fixed a bug in the Windows build where relative symbolic links were not
461 captured in reparse-point fixup mode.
463 Fixed a bug in the Windows build where file handles were left open to
464 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
466 Fixed a bug in the Windows build of wimlib-imagex where globbing
467 split-WIM parts could cause the program to crash.
469 Fixed a bug where the creation time of WIM images would be shown instead
470 of the last modification time.
472 With the Windows build it is now possible to restore a WIM containing
473 symbolic links as a non-Administrator; however you will receive warnings
474 about not being able to extract the symbolic links.
477 Capturing a WIM image should now be significantly faster in most cases
478 due to improved use of the operating system's cache and avoiding reading
479 files twice whenever possible.
481 The Windows build should now work on Windows XP.
483 The Windows build now supports capturing and restoring hidden,
484 compressed, sparse, and encrypted files.
486 The Windows build now supports capturing and applying WIM images from
487 filesystems other than NTFS (with some reduced functionality).
489 The Windows build now extracts short names correctly.
491 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
492 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
493 capture' and `wimlib-imagex apply'.
495 The performance of splitting and joining WIMs should be slightly
498 The LZX and XPRESS compression and decompression functions are now
499 exported from the library.
502 Improvements and bugfixes for the Windows build.
504 Added --strict-acls options.
506 Fixed the way that wimlib determines the order of images in the WIM.
509 Since wimlib can now be used on Windows, wimlib's implementation of
510 ImageX has been renamed to wimlib-imagex to avoid confusion with
511 Microsoft's implementation of ImageX, which would have the same file
512 name ("imagex.exe"). If you really don't like this you can pass the
513 --with-imagex-progname option to `configure' to choose a different name,
514 or even simply rename the binary yourself (but the former way will
515 configure the man pages to use the chosen name).
517 Various bugs fixed in the Windows build. Mainly to do with capturing
518 and restoring alternate data streams correctly in weird cases, and
519 requesting the correct privileges when opening files. Also added the
520 --noacls options to wimlib-imagex capture, append, and apply.
522 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
523 dynamically loaded, so this may make the library compatible with Windows
524 XP (however, there may still be other problems).
527 Added experimental support for native Windows builds. Binaries can be
528 downloaded from the SourceForge page.
530 --source-list option added to `imagex capture' and `imagex append'.
532 Better support for different character encodings.
535 Storing UNIX file owners, groups, and modes in WIM images is now
536 possible using `imagex capture' with the --unix-data flag.
538 Minor bug fixes and documentation fixes.
541 NTFS capture: Fixed capturing duplicate reparse points.
543 NTFS capture: Capture first unnamed stream if there are more than one
544 (print warning instead of error).
546 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
549 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
552 Update to work with ntfs-3g version 2013.1.13.
555 Fixed truncating file to shorter but non-zero length on read-write
558 Various code cleanups and minor documentation fixes.
561 LZX and XPRESS decompression have received some additional optimizations
562 and should now be even faster. (Although, they were already pretty
563 fast--- much faster than typical I/O speeds.)
565 Fixed a bug introduced in v1.2.1 that would cause a directory tree
566 containing hard links to be captured incorrectly in some cases.
569 By default, unmounting a read-write mounted WIM with 'imagex unmount
570 --commit' will now change the WIM in-place without needing to write the
571 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
574 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
575 for a response from the daemon servicing the mounted WIM. Instead,
576 every second 'imagex unmount' will check if the daemon is still alive,
577 and keep waiting if so, otherwise terminate with an error.
579 'imagex unmount --commit' on a read-write mounted WIM will now print
580 progress information regarding the writing of new or modified streams
581 the WIM, just like when capturing or appending a WIM.
583 A small change has been made to XPRESS compression and it should improve
584 the compression ratio slightly.
586 A change was made that may improve performance slightly when applying a
587 WIM image to a NTFS volume.
589 Microsoft has managed to introduce even more bugs into their software,
590 and now the WIMs for Windows 8 have incorrect (too low) reference counts
591 for some streams. This is unsafe because such streams can be removed
592 when they are in actuality still referenced in the WIM (perhaps by a
593 different image). wimlib will now work around this problem by fixing
594 the stream reference counts. This is only done when wimlib_delete_image() is
595 called ('imagex delete') or when wimlib_mount_image() is called with
596 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
597 requires reading the metadata for all images in the WIM, so this will
598 make these operations noticably slower on WIMs with multiple images.
600 Various other bugfixes.
603 Appending images to a WIM is now be done by default without re-building
604 the whole WIM. Use the --rebuild flag to get the old behavior (which
605 was to re-build the entire WIM when a new image is appended).
607 A new command `imagex optimize' is now available to manually re-build a
608 WIM that has wasted space due to repeated appends.
610 Progress information has been improved, and now arbitrary callback
611 functions can be used to show the progress of a WIM operation.
613 A possible bug with changing the bootable image of a WIM was fixed.
615 Some advisory locking is now done to prevent two processes from
616 modifying a WIM at the same time (but only in some cases). For example,
617 you cannot mount two images from a WIM read-write at the same time.
619 Some functions have been reorganized:
620 * wimlib_mount() renamed to wimlib_mount_image().
621 * wimlib_unmount() renamed to wimlib_unmount_image().
622 * wimlib_overwrite_xml_and_header() removed as
623 wimlib_overwrite() suffices now.
624 * wimlib_apply_image_to_ntfs_volume() removed as
625 wimlib_extract_image() suffices now.
626 * wimlib_add_image_from_ntfs_volume() removed as
627 * wimlib_add_image() suffices now.
629 Previously, the soname of libwim.so has been 0.0.0, despite many
630 interface changes. The soname is now updated to 1.0.0 and will now be
631 updated each release.
634 Resources will now be compressed using multiple threads by default.
635 (This applies to `imagex capture', `imagex append', and `imagex
638 Some performance improvements in mounted WIMs.
640 More progress information is shown when capturing a WIM.
643 Lots of minor fixes, code cleanups, and some documentation updates.
644 Nothing in particular is really noteworthy.
647 LZX and XPRESS compression improvements.
649 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
650 Link Bytes of the WIM.
653 Fixed bug when capturing NTFS file with multiple named data streams.
655 Internally, we are now using inode structures, even though these don't
656 appear literally in the WIM file. This simplifies some of the code
657 (mainly for WIM mounting) and likely fixed a few problems, although it
661 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
665 Enough changes to call it version 1.0.0!
667 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
668 to a NTFS volume, is now supported.
670 Hard links and symbolic links have much improved support. They are
671 supported for WIM capture, WIM application, and mounted WIMs (you can
672 even make them on read-write mounted WIMs).
674 Alternate data streams are now supported on mounted WIMs through an
675 xattr or a Windows-style stream interface. Also they are supported when
676 capturing a WIM from NTFS or applying a WIM to NTFS.
678 Split WIMs are better supported. You may now apply an image directly
679 from a split WIM, mount an image from a split WIM read-only, or export
680 an image from a split WIM.
682 Using a capture configuration file is now supported (but not fully yet).
684 SHA1 message digests are checked in more places, so we can make sure
685 applied and captured data is correct.
687 Man pages have been updated and consolidated.
690 Fixed segfault when unmounting read-only WIM.
693 Support for joining and splitting WIMs.
694 Also, security data is now preserved by default.
697 Can now build with older gcc and system headers, like on CentOS 5.
700 Fixed bug that made it impossible to overwrite files in read-write
704 Write byte-order mark before WIM XML data. (imagex.exe requires this to
