2 The library now permits making in-memory changes to a WIMStruct backed
3 by a read-only WIM file.
6 Made more improvements to the XPRESS, LZX, and LZMS compressors.
8 A number of improvements to the Windows port:
10 Fixes for setting short filenames.
12 Faster "WIMBoot" extraction.
14 Updated and slimmed down the dependent DLLs.
16 ACL inheritence bits are now restored.
18 Mandatory integrity labels are now backed up and restored.
20 Added a workaround for an issue where in rare cases, wimlib could create
21 a compressed data stream that could not be read correctly by Windows
22 after an extraction in "WIMBoot" mode.
25 Added file count progress data for
26 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
27 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
29 Added support for testing file exclusions via the user-provided
32 Some documentation improvements.
34 Made some clarifications to the license text in the COPYING file.
37 Made more improvements to the XPRESS, LZX, and LZMS compressors.
39 The default compression mode for wimcapture is now LZX compression in
40 its default mode, which is the same as '--compress=maximum'.
42 You can now specify an optional integer compression level to the
43 '--compress' option; e.g. '--compress=lzx:75'.
45 Made a minor change to the LZMS compressor and decompressor to fix an
46 incompatibility with the Microsoft implementation. In the unlikely
47 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
48 earlier and a checksum error is reported when extracting files from it
49 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
52 Added 'verify' subcommand to wimlib-imagex.
54 Notable library changes:
56 Custom compressor parameters have been removed from the library
57 in favor of the simpler level-based API.
59 Decompressor parameters have been removed entirely.
61 Library users can now specify a custom file for warning and
62 error messages to be sent to, rather than the default of
65 New progress messages:
66 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
67 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
69 New function: wimlib_verify_wim().
72 Improved compression, decompression, and extraction performance.
74 Improved compatibility with version 3584 WIM / ESD files:
75 - Add support for reading and writing multiple solid blocks per
76 archive, which WIMGAPI/DISM can create when appending an image.
77 - Correctly create solid blocks larger than 4 GiB.
79 'add' commands passed to wimupdate will now replace existing
80 nondirectory files by default. Use the --no-replace option to get the
83 The license for the library now contains an exception that allows using
84 it under the LGPL. See the COPYING file for details.
86 In reparse-point fixup mode (the default for capture), symbolic links
87 and junctions that point outside the tree being captured are no longer
88 excluded from capture.
90 Added support for "WIMBoot" capture and extraction. See the
91 documentation for the new '--wimboot' option to wimcapture and wimapply
94 On UNIX-like systems, you can now backup and restore device nodes, named
95 pipes, and sockets. In addition, 32-bit user and group IDs are now
98 The way that UNIX data is stored in WIM files has been changed. If you
99 captured any WIMs with the --unix-data option, to upgrade them you'll
100 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
101 re-capture them with --unix-data using this version.
103 wimlib now understands tagged metadata items, such as object IDs, that
104 can be stored in WIM directory entries.
106 Removed the --hardlink and --symlink options to wimapply, since I don't
107 think they are too useful and they got in the way of improving the code.
109 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
111 The 'mkwinpeimg' script now supports writing the ISO image to standard
114 The <ARCH> element in WIM XML data is now exported correctly.
116 On Windows, sparse file attributes are no longer set on extracted files.
117 Oddly enough, this actually saves disk space in some cases.
119 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
120 supported. Mounting WIM images now always requires extended attribute
121 support. Use --without-fuse to disable support for mounting WIM images;
122 this will also disable the need for extended attribute support.
124 Configuring with --enable-ssse3-sha1 now works correctly.
126 The shared library version has been bumped up. The main
127 incompatibilities are:
129 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
130 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
133 - User-provided progress functions are now registered using a
134 separate function, wimlib_register_progress_function(). The
135 'progress_func' argument to many functions no longer exists.
137 - The return value from user-provided progress functions is now
140 - A context argument has been added to the prototype of
141 user-provided progress functions.
143 - 'struct wimlib_capture_config' has been removed. The library
144 now takes the path to the configuration file directly. This
145 affects wimlib_add_image(), wimlib_add_image_multisource(),
146 and wimlib_update_image(). However, a NULL value passed in
147 the argument retains the same meaning.
149 - Removed deprecated functions: some (de)compression functions,
150 wimlib_extract_files(), and wimlib_print_metadata().
152 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
153 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
154 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
156 - Removed some progress messages:
157 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
158 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
159 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
162 - Removed some error codes. Numbering stays the same.
164 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
165 WIMLIB_UNMOUNT_FLAG_FORCE.
167 - WIM paths passed to progress functions now have a leading
171 Case-insensitive comparisons of strings (e.g. filenames) containing
172 UTF-16 codepoints above 32767 are now done correctly.
174 Fixed build failure on Mac OS X.
176 wimunmount now provides the '--new-image' option to cause changes to a
177 read-write mounted image to be committed as a new image rather than as
178 an update of the mounted image. (The corresponding new library flag is
179 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
181 The LZMS ("recovery") compression chunk size, or "dictionary size", may
182 now be up to 1 GiB (1,073,741,824 bytes).
184 The performance of LZX ("maximum") and LZMS ("recovery") compression
185 with large chunk sizes has been slightly improved.
188 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
189 decompressed correctly.
191 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
192 occurred in an unlikely case, and due to validity checks it did not
193 affect successfully created archives.
195 Fixed a minor compatibility issue with the LZMS compressor and
196 decompressor. This is *not* the default compression type and was only
197 introduced in v1.6.0. In the unlikely event that you created an
198 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
199 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
202 Memory usage for LZMS and LZX compression has been decreased.
204 wimextract now allows wildcard characters in paths specified on the
205 command line. Also, the '--strict-wildcards' option has been removed
206 and replaced with the inverse option '--nullglob'. See the
207 documentation for wimextract for more details and changes.
209 The wimlib_extract_files() function is now considered deprecated in
210 favor of wimlib_extract_paths().
212 Fixed more permissions problems when extracting files on Windows.
214 A new '--no-attributes' option has been added to wimapply and
215 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
217 The default chunk size is now set correctly when changing the
218 compression type of a WIM, for example with 'wimoptimize'.
220 The '--metadata' option to wiminfo has been replaced with the
221 '--detailed' option to wimdir.
223 In relevant wimlib-imagex commands, '--solid' may now be used as an
224 alias for '--pack-streams'.
227 Support for extracting and updating the new version 3584 WIMs has been
228 added. These WIMs typically pack many streams ("files") together into a
229 single compressed resource, thereby saving space. This degrades the
230 performance of random access (such as that which occurs on a mounted
231 image), but optimizations have been implemented for extraction. These
232 new WIM files also typically use a new compression format (LZMS), which
233 is similar to LZMA and can offer a better compression ratio than LZX.
234 These new WIM files can be created using `wimcapture' with
235 the '--compress=lzms --pack-streams' options. Note: this new WIM format
236 is used by the Windows 8 web downloader, but important segments of the
237 raw '.esd' files are encrypted, so wimlib will not be able to extract
238 such files until they are first decrypted.
240 wimlib now supports extracting files and directories from a WIM image
241 based on a "listfile" that itself contains the list of paths to extract.
242 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
243 and for the library itself, the new APIs are wimlib_extract_pathlist()
244 and wimlib_extract_paths(). Path globs containing wildcard characters
247 For searching WIM files, wimlib now has configurable case sensitivity.
248 The default on Windows is still case-insensitive and the default on
249 UNIX-like systems is still case-sensitive, but this can be overridden
250 on either platform through flags to wimlib_global_init(). For
251 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
252 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
255 Support for compression chunk sizes greater than the default of 32768
256 bytes has been added. A larger chunk size typically results in a better
257 compression ratio. However, the MS implementation is seemingly not
258 compatible with all chunk sizes, especially for LZX compression, so the
259 defaults remain unchanged, with the exception of the new LZMS-compressed
260 WIMs, which use a larger chunk size by default.
262 The compression/decompression API exported by wimlib has been changed.
263 Now one set of functions handles all supported compression formats.
265 `wimcapture' and `wimappend' will now display the progress of scanning
266 the directory tree to capture, in addition to the progress of writing
267 data to the WIM. The '--verbose' option no longer does anything. The
268 library API change for this is the addition of several members to
269 `struct wimlib_progress_info_scan' available to progress callbacks.
271 `mkwinpeimg' now correctly handles the '--start-script' option when the
272 start script is not in the working directory.
274 Sequential extraction, previously requested by using
275 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
276 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
277 behavior (extract in file order).
280 The new LZX compressor added in v1.5.2 has been improved and is now
281 enabled by default, except when `wimcapture' or `wimappend' is run
282 *without* the '--compress' option, in which case the faster LZX
283 compressor is used (the same as before). This behavior is reasonably
284 consistent with ImageX which actually uses "fast" (XPRESS) compression
285 by default. In those cases, use '--compress=maximum' to explicitly
286 capture a WIM image using the new (slower but better) LZX compressor.
288 The '--compress-slow' option still exists to `wimlib-imagex optimize',
289 but its new behavior is to tweak the new LZX compressor even more to
290 produce an even better compression ratio at the cost of more time spent
293 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
294 which recompresses the WIM file using the specified compression TYPE.
295 The new library API function used for this is
296 wimlib_set_output_compression_type().
298 Added the wimlib_get_xml_data() function to allow library clients to
299 easily retrieve the raw XML data from a WIM file if needed.
301 Fixed a bug that could cause an error code to be incorrectly returned
302 when writing XML data containing a <WINDOWS> element.
304 Mounted WIM images will now correctly show the default file stream even
305 if appears in the alternate data stream entries of the corresponding WIM
309 Added a new experimental LZX compressor which can be enabled by passing
310 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
311 optimize'. (The latter is only applicable if the WIM is already
312 LZX-compressed and the '--recompress' option is also given.) The
313 experimental compressor is much slower but compresses the data slightly
314 more --- currently usually to within a fraction of a percent of the
315 results from WIMGAPI/ImageX.
317 A workaround has been added for compatibility with versions of WinPE
318 that interpret alternate data stream entries in the boot WIM
321 An alignment bug that caused a crash in the LZX decompressor on some
324 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
325 the WIM header when restoring the previous state of a WIM it failed to
328 Added a workaround to avoid an access denied error on Windows when
329 replacing a WIM file that another process has opened.
332 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
333 needed to be handled.
335 A bug in the interpretation of negative IMAGE indices in the
336 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
337 `wimlib-imagex append' has been fixed.
339 A workaround has been added to successfully apply security descriptors
340 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
341 2013.1.13 or earlier.
343 `wimlib-imagex capture' can now accept the '--delta-from' option
347 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
348 to standard output and applying images from standard input, but they are
349 not compatible with Microsoft's software and are not created by default.
350 See the documentation for --pipable flag of `wimlib-imagex capture' for
353 To better support incremental backups, added support for declaring an
354 image as a modified form of another image. See the documentation for
355 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
358 Added supported for "delta" WIMs. See the documentation for the
359 '--delta-from' option of `wimlib-imagex capture'.
361 The library support for managing split WIMs has been changed to support
362 other arrangements, such as delta WIMs, and be easier to use. This
363 change is visible in `wimlib-imagex', which also can now accept the
364 '--ref' option multiple times, and also now supports "delta" WIMs as
367 wimlib now preserves WIM integrity tables by default, even if
368 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
369 behavior of `wimlib-imagex' whenever the WIM being operated on contains
370 an integrity table and the '--check' option is not specified.
372 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
373 (when --compress is not specified). This provides the best compression
374 ratio by default, which is usually what is desired, at a cost of some
377 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
378 is the command as in `wimlib-imagex COMMAND'; for example, it can be
379 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
380 appropriate hard links are created in UNIX installations of
381 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
382 batch files that emulate this behavior are generated.
384 Security descriptors are now extracted correctly on Windows.
386 Fixed archiving DOS names in NTFS-3g capture mode.
388 The extraction code has been rewritten and it will now be easier to
389 support new features on all supported backends (currently Win32, UNIX,
390 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
391 now supported on all backends, not just UNIX.
393 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
394 than the WAIK itself.
396 wimlib_global_init() now, by default, attempts to acquire additional
397 privileges on Windows, so library clients need not do this.
399 This update bumps the shared library version number up to 9, since it is
400 not binary compatibible with previous releases.
403 Fixed bug in `wimlib-imagex export' that made it impossible to export an
404 image from a WIM that is readonly at the filesystem level.
406 Return error code rather than segfaulting when trying to list files from
407 a non-first part of a split WIM.
409 Joining a WIM will now preserve the RP_FIX and READONLY flags.
412 On Windows, paths given to wimlib-imagex are now treated case
415 Improved behavior regarding invalid filenames; in particular, on
416 Windows, wimlib-imagex will, when extracting, now omit (with an option
417 to override this default) filenames differing only in case, or filenames
418 containing characters not valid on Windows.
420 On Windows, wimlib now supports capturing and extracting long paths
421 (longer than the so-called MAX_PATH).
423 On Windows, `wimlib-imagex update' now acquires proper privileges when
424 running as an Administrator.
426 `wimlib-imagex update' will now complain if no image is specified when
427 trying to update a multi-image WIM.
429 `wimlib-imagex update' now supports specifying a single update command
430 directly on the command line using the --command option.
432 wimlib-imagex will now choose different units for progress messages,
433 depending on the amount of data that needs to be processed.
435 `wimlib-imagex append' will now generate a unique WIM image name if no
436 name is specified and the defaulted name already exists in the WIM.
438 wimlib now allows you to create unnamed WIM images, which can then only
439 be referred to by index.
441 wimlib now allows you to explicitly declare you want write access to a
442 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
445 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
448 Progress callbacks have been added to wimlib's wimlib_update_image()
451 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
452 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
455 NTFS-3g capture now only warns about two conditions previously treated
458 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
461 wimlib now correctly detects and returns an error when reading a WIM
462 image with a cyclic directory structure. (Fun fact: such a WIM will
463 crash Microsoft's software.)
466 Added new "extract" and "update" subcommands to wimlib-imagex, along
467 with associated APIs in the library. These commands are intended mainly
468 for Windows use but can be used on UNIX as well.
470 Many documentation improvements.
472 Fixed a bug in the Windows build where relative symbolic links were not
473 captured in reparse-point fixup mode.
475 Fixed a bug in the Windows build where file handles were left open to
476 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
478 Fixed a bug in the Windows build of wimlib-imagex where globbing
479 split-WIM parts could cause the program to crash.
481 Fixed a bug where the creation time of WIM images would be shown instead
482 of the last modification time.
484 With the Windows build it is now possible to restore a WIM containing
485 symbolic links as a non-Administrator; however you will receive warnings
486 about not being able to extract the symbolic links.
489 Capturing a WIM image should now be significantly faster in most cases
490 due to improved use of the operating system's cache and avoiding reading
491 files twice whenever possible.
493 The Windows build should now work on Windows XP.
495 The Windows build now supports capturing and restoring hidden,
496 compressed, sparse, and encrypted files.
498 The Windows build now supports capturing and applying WIM images from
499 filesystems other than NTFS (with some reduced functionality).
501 The Windows build now extracts short names correctly.
503 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
504 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
505 capture' and `wimlib-imagex apply'.
507 The performance of splitting and joining WIMs should be slightly
510 The LZX and XPRESS compression and decompression functions are now
511 exported from the library.
514 Improvements and bugfixes for the Windows build.
516 Added --strict-acls options.
518 Fixed the way that wimlib determines the order of images in the WIM.
521 Since wimlib can now be used on Windows, wimlib's implementation of
522 ImageX has been renamed to wimlib-imagex to avoid confusion with
523 Microsoft's implementation of ImageX, which would have the same file
524 name ("imagex.exe"). If you really don't like this you can pass the
525 --with-imagex-progname option to `configure' to choose a different name,
526 or even simply rename the binary yourself (but the former way will
527 configure the man pages to use the chosen name).
529 Various bugs fixed in the Windows build. Mainly to do with capturing
530 and restoring alternate data streams correctly in weird cases, and
531 requesting the correct privileges when opening files. Also added the
532 --noacls options to wimlib-imagex capture, append, and apply.
534 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
535 dynamically loaded, so this may make the library compatible with Windows
536 XP (however, there may still be other problems).
539 Added experimental support for native Windows builds. Binaries can be
540 downloaded from the SourceForge page.
542 --source-list option added to `imagex capture' and `imagex append'.
544 Better support for different character encodings.
547 Storing UNIX file owners, groups, and modes in WIM images is now
548 possible using `imagex capture' with the --unix-data flag.
550 Minor bug fixes and documentation fixes.
553 NTFS capture: Fixed capturing duplicate reparse points.
555 NTFS capture: Capture first unnamed stream if there are more than one
556 (print warning instead of error).
558 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
561 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
564 Update to work with ntfs-3g version 2013.1.13.
567 Fixed truncating file to shorter but non-zero length on read-write
570 Various code cleanups and minor documentation fixes.
573 LZX and XPRESS decompression have received some additional optimizations
574 and should now be even faster. (Although, they were already pretty
575 fast--- much faster than typical I/O speeds.)
577 Fixed a bug introduced in v1.2.1 that would cause a directory tree
578 containing hard links to be captured incorrectly in some cases.
581 By default, unmounting a read-write mounted WIM with 'imagex unmount
582 --commit' will now change the WIM in-place without needing to write the
583 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
586 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
587 for a response from the daemon servicing the mounted WIM. Instead,
588 every second 'imagex unmount' will check if the daemon is still alive,
589 and keep waiting if so, otherwise terminate with an error.
591 'imagex unmount --commit' on a read-write mounted WIM will now print
592 progress information regarding the writing of new or modified streams
593 the WIM, just like when capturing or appending a WIM.
595 A small change has been made to XPRESS compression and it should improve
596 the compression ratio slightly.
598 A change was made that may improve performance slightly when applying a
599 WIM image to a NTFS volume.
601 Microsoft has managed to introduce even more bugs into their software,
602 and now the WIMs for Windows 8 have incorrect (too low) reference counts
603 for some streams. This is unsafe because such streams can be removed
604 when they are in actuality still referenced in the WIM (perhaps by a
605 different image). wimlib will now work around this problem by fixing
606 the stream reference counts. This is only done when wimlib_delete_image() is
607 called ('imagex delete') or when wimlib_mount_image() is called with
608 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
609 requires reading the metadata for all images in the WIM, so this will
610 make these operations noticably slower on WIMs with multiple images.
612 Various other bugfixes.
615 Appending images to a WIM is now be done by default without re-building
616 the whole WIM. Use the --rebuild flag to get the old behavior (which
617 was to re-build the entire WIM when a new image is appended).
619 A new command `imagex optimize' is now available to manually re-build a
620 WIM that has wasted space due to repeated appends.
622 Progress information has been improved, and now arbitrary callback
623 functions can be used to show the progress of a WIM operation.
625 A possible bug with changing the bootable image of a WIM was fixed.
627 Some advisory locking is now done to prevent two processes from
628 modifying a WIM at the same time (but only in some cases). For example,
629 you cannot mount two images from a WIM read-write at the same time.
631 Some functions have been reorganized:
632 * wimlib_mount() renamed to wimlib_mount_image().
633 * wimlib_unmount() renamed to wimlib_unmount_image().
634 * wimlib_overwrite_xml_and_header() removed as
635 wimlib_overwrite() suffices now.
636 * wimlib_apply_image_to_ntfs_volume() removed as
637 wimlib_extract_image() suffices now.
638 * wimlib_add_image_from_ntfs_volume() removed as
639 * wimlib_add_image() suffices now.
641 Previously, the soname of libwim.so has been 0.0.0, despite many
642 interface changes. The soname is now updated to 1.0.0 and will now be
643 updated each release.
646 Resources will now be compressed using multiple threads by default.
647 (This applies to `imagex capture', `imagex append', and `imagex
650 Some performance improvements in mounted WIMs.
652 More progress information is shown when capturing a WIM.
655 Lots of minor fixes, code cleanups, and some documentation updates.
656 Nothing in particular is really noteworthy.
659 LZX and XPRESS compression improvements.
661 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
662 Link Bytes of the WIM.
665 Fixed bug when capturing NTFS file with multiple named data streams.
667 Internally, we are now using inode structures, even though these don't
668 appear literally in the WIM file. This simplifies some of the code
669 (mainly for WIM mounting) and likely fixed a few problems, although it
673 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
677 Enough changes to call it version 1.0.0!
679 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
680 to a NTFS volume, is now supported.
682 Hard links and symbolic links have much improved support. They are
683 supported for WIM capture, WIM application, and mounted WIMs (you can
684 even make them on read-write mounted WIMs).
686 Alternate data streams are now supported on mounted WIMs through an
687 xattr or a Windows-style stream interface. Also they are supported when
688 capturing a WIM from NTFS or applying a WIM to NTFS.
690 Split WIMs are better supported. You may now apply an image directly
691 from a split WIM, mount an image from a split WIM read-only, or export
692 an image from a split WIM.
694 Using a capture configuration file is now supported (but not fully yet).
696 SHA1 message digests are checked in more places, so we can make sure
697 applied and captured data is correct.
699 Man pages have been updated and consolidated.
702 Fixed segfault when unmounting read-only WIM.
705 Support for joining and splitting WIMs.
706 Also, security data is now preserved by default.
709 Can now build with older gcc and system headers, like on CentOS 5.
712 Fixed bug that made it impossible to overwrite files in read-write
716 Write byte-order mark before WIM XML data. (imagex.exe requires this to
