2 Extracting files to a Windows PE in-memory filesystem no longer fails if
3 the target files do not yet exist. (Broken since v1.7.0, but actually a
4 result of a Microsoft bug.)
6 More fixes for wimlib on non-x86 architectures such as ARM.
8 Slight performance improvements in compression and decompression.
11 Fix for very slow export from solid WIM / ESD files.
13 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
15 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
16 may use this to treat some types of errors as non-fatal.
18 The library now permits making in-memory changes to a WIMStruct backed
19 by a read-only WIM file.
21 Fixes for "WIMBoot" extraction mode (Windows only):
23 When not using the WOF driver, extraction no longer fails if the
24 disk containing the WIM file has too many partitions.
26 When matching patterns in [PrepopulateList], all hard links of
27 each file are now considered.
29 The system registry files are now automatically treated as being
32 Added a hack to try to work around an intermittent bug in
33 Microsoft's WOF (Windows Overlay Filesystem) driver.
36 Made more improvements to the XPRESS, LZX, and LZMS compressors.
38 A number of improvements to the Windows port:
40 Fixes for setting short filenames.
42 Faster "WIMBoot" extraction.
44 Updated and slimmed down the dependent DLLs.
46 ACL inheritence bits are now restored.
48 Mandatory integrity labels are now backed up and restored.
50 Added a workaround for an issue where in rare cases, wimlib could create
51 a compressed data stream that could not be read correctly by Windows
52 after an extraction in "WIMBoot" mode.
55 Added file count progress data for
56 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
57 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
59 Added support for testing file exclusions via the user-provided
62 Some documentation improvements.
64 Made some clarifications to the license text in the COPYING file.
67 Made more improvements to the XPRESS, LZX, and LZMS compressors.
69 The default compression mode for wimcapture is now LZX compression in
70 its default mode, which is the same as '--compress=maximum'.
72 You can now specify an optional integer compression level to the
73 '--compress' option; e.g. '--compress=lzx:75'.
75 Made a minor change to the LZMS compressor and decompressor to fix an
76 incompatibility with the Microsoft implementation. In the unlikely
77 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
78 earlier and a checksum error is reported when extracting files from it
79 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
82 Added 'verify' subcommand to wimlib-imagex.
84 Notable library changes:
86 Custom compressor parameters have been removed from the library
87 in favor of the simpler level-based API.
89 Decompressor parameters have been removed entirely.
91 Library users can now specify a custom file for warning and
92 error messages to be sent to, rather than the default of
95 New progress messages:
96 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
97 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
99 New function: wimlib_verify_wim().
102 Improved compression, decompression, and extraction performance.
104 Improved compatibility with version 3584 WIM / ESD files:
105 - Add support for reading and writing multiple solid blocks per
106 archive, which WIMGAPI/DISM can create when appending an image.
107 - Correctly create solid blocks larger than 4 GiB.
109 'add' commands passed to wimupdate will now replace existing
110 nondirectory files by default. Use the --no-replace option to get the
113 The license for the library now contains an exception that allows using
114 it under the LGPL. See the COPYING file for details.
116 In reparse-point fixup mode (the default for capture), symbolic links
117 and junctions that point outside the tree being captured are no longer
118 excluded from capture.
120 Added support for "WIMBoot" capture and extraction. See the
121 documentation for the new '--wimboot' option to wimcapture and wimapply
122 for more information.
124 On UNIX-like systems, you can now backup and restore device nodes, named
125 pipes, and sockets. In addition, 32-bit user and group IDs are now
128 The way that UNIX data is stored in WIM files has been changed. If you
129 captured any WIMs with the --unix-data option, to upgrade them you'll
130 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
131 re-capture them with --unix-data using this version.
133 wimlib now understands tagged metadata items, such as object IDs, that
134 can be stored in WIM directory entries.
136 Removed the --hardlink and --symlink options to wimapply, since I don't
137 think they are too useful and they got in the way of improving the code.
139 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
141 The 'mkwinpeimg' script now supports writing the ISO image to standard
144 The <ARCH> element in WIM XML data is now exported correctly.
146 On Windows, sparse file attributes are no longer set on extracted files.
147 Oddly enough, this actually saves disk space in some cases.
149 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
150 supported. Mounting WIM images now always requires extended attribute
151 support. Use --without-fuse to disable support for mounting WIM images;
152 this will also disable the need for extended attribute support.
154 Configuring with --enable-ssse3-sha1 now works correctly.
156 The shared library version has been bumped up. The main
157 incompatibilities are:
159 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
160 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
163 - User-provided progress functions are now registered using a
164 separate function, wimlib_register_progress_function(). The
165 'progress_func' argument to many functions no longer exists.
167 - The return value from user-provided progress functions is now
170 - A context argument has been added to the prototype of
171 user-provided progress functions.
173 - 'struct wimlib_capture_config' has been removed. The library
174 now takes the path to the configuration file directly. This
175 affects wimlib_add_image(), wimlib_add_image_multisource(),
176 and wimlib_update_image(). However, a NULL value passed in
177 the argument retains the same meaning.
179 - Removed deprecated functions: some (de)compression functions,
180 wimlib_extract_files(), and wimlib_print_metadata().
182 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
183 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
184 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
186 - Removed some progress messages:
187 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
188 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
189 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
192 - Removed some error codes. Numbering stays the same.
194 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
195 WIMLIB_UNMOUNT_FLAG_FORCE.
197 - WIM paths passed to progress functions now have a leading
201 Case-insensitive comparisons of strings (e.g. filenames) containing
202 UTF-16 codepoints above 32767 are now done correctly.
204 Fixed build failure on Mac OS X.
206 wimunmount now provides the '--new-image' option to cause changes to a
207 read-write mounted image to be committed as a new image rather than as
208 an update of the mounted image. (The corresponding new library flag is
209 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
211 The LZMS ("recovery") compression chunk size, or "dictionary size", may
212 now be up to 1 GiB (1,073,741,824 bytes).
214 The performance of LZX ("maximum") and LZMS ("recovery") compression
215 with large chunk sizes has been slightly improved.
218 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
219 decompressed correctly.
221 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
222 occurred in an unlikely case, and due to validity checks it did not
223 affect successfully created archives.
225 Fixed a minor compatibility issue with the LZMS compressor and
226 decompressor. This is *not* the default compression type and was only
227 introduced in v1.6.0. In the unlikely event that you created an
228 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
229 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
232 Memory usage for LZMS and LZX compression has been decreased.
234 wimextract now allows wildcard characters in paths specified on the
235 command line. Also, the '--strict-wildcards' option has been removed
236 and replaced with the inverse option '--nullglob'. See the
237 documentation for wimextract for more details and changes.
239 The wimlib_extract_files() function is now considered deprecated in
240 favor of wimlib_extract_paths().
242 Fixed more permissions problems when extracting files on Windows.
244 A new '--no-attributes' option has been added to wimapply and
245 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
247 The default chunk size is now set correctly when changing the
248 compression type of a WIM, for example with 'wimoptimize'.
250 The '--metadata' option to wiminfo has been replaced with the
251 '--detailed' option to wimdir.
253 In relevant wimlib-imagex commands, '--solid' may now be used as an
254 alias for '--pack-streams'.
257 Support for extracting and updating the new version 3584 WIMs has been
258 added. These WIMs typically pack many streams ("files") together into a
259 single compressed resource, thereby saving space. This degrades the
260 performance of random access (such as that which occurs on a mounted
261 image), but optimizations have been implemented for extraction. These
262 new WIM files also typically use a new compression format (LZMS), which
263 is similar to LZMA and can offer a better compression ratio than LZX.
264 These new WIM files can be created using `wimcapture' with
265 the '--compress=lzms --pack-streams' options. Note: this new WIM format
266 is used by the Windows 8 web downloader, but important segments of the
267 raw '.esd' files are encrypted, so wimlib will not be able to extract
268 such files until they are first decrypted.
270 wimlib now supports extracting files and directories from a WIM image
271 based on a "listfile" that itself contains the list of paths to extract.
272 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
273 and for the library itself, the new APIs are wimlib_extract_pathlist()
274 and wimlib_extract_paths(). Path globs containing wildcard characters
277 For searching WIM files, wimlib now has configurable case sensitivity.
278 The default on Windows is still case-insensitive and the default on
279 UNIX-like systems is still case-sensitive, but this can be overridden
280 on either platform through flags to wimlib_global_init(). For
281 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
282 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
285 Support for compression chunk sizes greater than the default of 32768
286 bytes has been added. A larger chunk size typically results in a better
287 compression ratio. However, the MS implementation is seemingly not
288 compatible with all chunk sizes, especially for LZX compression, so the
289 defaults remain unchanged, with the exception of the new LZMS-compressed
290 WIMs, which use a larger chunk size by default.
292 The compression/decompression API exported by wimlib has been changed.
293 Now one set of functions handles all supported compression formats.
295 `wimcapture' and `wimappend' will now display the progress of scanning
296 the directory tree to capture, in addition to the progress of writing
297 data to the WIM. The '--verbose' option no longer does anything. The
298 library API change for this is the addition of several members to
299 `struct wimlib_progress_info_scan' available to progress callbacks.
301 `mkwinpeimg' now correctly handles the '--start-script' option when the
302 start script is not in the working directory.
304 Sequential extraction, previously requested by using
305 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
306 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
307 behavior (extract in file order).
310 The new LZX compressor added in v1.5.2 has been improved and is now
311 enabled by default, except when `wimcapture' or `wimappend' is run
312 *without* the '--compress' option, in which case the faster LZX
313 compressor is used (the same as before). This behavior is reasonably
314 consistent with ImageX which actually uses "fast" (XPRESS) compression
315 by default. In those cases, use '--compress=maximum' to explicitly
316 capture a WIM image using the new (slower but better) LZX compressor.
318 The '--compress-slow' option still exists to `wimlib-imagex optimize',
319 but its new behavior is to tweak the new LZX compressor even more to
320 produce an even better compression ratio at the cost of more time spent
323 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
324 which recompresses the WIM file using the specified compression TYPE.
325 The new library API function used for this is
326 wimlib_set_output_compression_type().
328 Added the wimlib_get_xml_data() function to allow library clients to
329 easily retrieve the raw XML data from a WIM file if needed.
331 Fixed a bug that could cause an error code to be incorrectly returned
332 when writing XML data containing a <WINDOWS> element.
334 Mounted WIM images will now correctly show the default file stream even
335 if appears in the alternate data stream entries of the corresponding WIM
339 Added a new experimental LZX compressor which can be enabled by passing
340 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
341 optimize'. (The latter is only applicable if the WIM is already
342 LZX-compressed and the '--recompress' option is also given.) The
343 experimental compressor is much slower but compresses the data slightly
344 more --- currently usually to within a fraction of a percent of the
345 results from WIMGAPI/ImageX.
347 A workaround has been added for compatibility with versions of WinPE
348 that interpret alternate data stream entries in the boot WIM
351 An alignment bug that caused a crash in the LZX decompressor on some
354 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
355 the WIM header when restoring the previous state of a WIM it failed to
358 Added a workaround to avoid an access denied error on Windows when
359 replacing a WIM file that another process has opened.
362 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
363 needed to be handled.
365 A bug in the interpretation of negative IMAGE indices in the
366 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
367 `wimlib-imagex append' has been fixed.
369 A workaround has been added to successfully apply security descriptors
370 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
371 2013.1.13 or earlier.
373 `wimlib-imagex capture' can now accept the '--delta-from' option
377 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
378 to standard output and applying images from standard input, but they are
379 not compatible with Microsoft's software and are not created by default.
380 See the documentation for --pipable flag of `wimlib-imagex capture' for
383 To better support incremental backups, added support for declaring an
384 image as a modified form of another image. See the documentation for
385 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
388 Added supported for "delta" WIMs. See the documentation for the
389 '--delta-from' option of `wimlib-imagex capture'.
391 The library support for managing split WIMs has been changed to support
392 other arrangements, such as delta WIMs, and be easier to use. This
393 change is visible in `wimlib-imagex', which also can now accept the
394 '--ref' option multiple times, and also now supports "delta" WIMs as
397 wimlib now preserves WIM integrity tables by default, even if
398 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
399 behavior of `wimlib-imagex' whenever the WIM being operated on contains
400 an integrity table and the '--check' option is not specified.
402 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
403 (when --compress is not specified). This provides the best compression
404 ratio by default, which is usually what is desired, at a cost of some
407 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
408 is the command as in `wimlib-imagex COMMAND'; for example, it can be
409 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
410 appropriate hard links are created in UNIX installations of
411 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
412 batch files that emulate this behavior are generated.
414 Security descriptors are now extracted correctly on Windows.
416 Fixed archiving DOS names in NTFS-3g capture mode.
418 The extraction code has been rewritten and it will now be easier to
419 support new features on all supported backends (currently Win32, UNIX,
420 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
421 now supported on all backends, not just UNIX.
423 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
424 than the WAIK itself.
426 wimlib_global_init() now, by default, attempts to acquire additional
427 privileges on Windows, so library clients need not do this.
429 This update bumps the shared library version number up to 9, since it is
430 not binary compatibible with previous releases.
433 Fixed bug in `wimlib-imagex export' that made it impossible to export an
434 image from a WIM that is readonly at the filesystem level.
436 Return error code rather than segfaulting when trying to list files from
437 a non-first part of a split WIM.
439 Joining a WIM will now preserve the RP_FIX and READONLY flags.
442 On Windows, paths given to wimlib-imagex are now treated case
445 Improved behavior regarding invalid filenames; in particular, on
446 Windows, wimlib-imagex will, when extracting, now omit (with an option
447 to override this default) filenames differing only in case, or filenames
448 containing characters not valid on Windows.
450 On Windows, wimlib now supports capturing and extracting long paths
451 (longer than the so-called MAX_PATH).
453 On Windows, `wimlib-imagex update' now acquires proper privileges when
454 running as an Administrator.
456 `wimlib-imagex update' will now complain if no image is specified when
457 trying to update a multi-image WIM.
459 `wimlib-imagex update' now supports specifying a single update command
460 directly on the command line using the --command option.
462 wimlib-imagex will now choose different units for progress messages,
463 depending on the amount of data that needs to be processed.
465 `wimlib-imagex append' will now generate a unique WIM image name if no
466 name is specified and the defaulted name already exists in the WIM.
468 wimlib now allows you to create unnamed WIM images, which can then only
469 be referred to by index.
471 wimlib now allows you to explicitly declare you want write access to a
472 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
475 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
478 Progress callbacks have been added to wimlib's wimlib_update_image()
481 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
482 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
485 NTFS-3g capture now only warns about two conditions previously treated
488 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
491 wimlib now correctly detects and returns an error when reading a WIM
492 image with a cyclic directory structure. (Fun fact: such a WIM will
493 crash Microsoft's software.)
496 Added new "extract" and "update" subcommands to wimlib-imagex, along
497 with associated APIs in the library. These commands are intended mainly
498 for Windows use but can be used on UNIX as well.
500 Many documentation improvements.
502 Fixed a bug in the Windows build where relative symbolic links were not
503 captured in reparse-point fixup mode.
505 Fixed a bug in the Windows build where file handles were left open to
506 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
508 Fixed a bug in the Windows build of wimlib-imagex where globbing
509 split-WIM parts could cause the program to crash.
511 Fixed a bug where the creation time of WIM images would be shown instead
512 of the last modification time.
514 With the Windows build it is now possible to restore a WIM containing
515 symbolic links as a non-Administrator; however you will receive warnings
516 about not being able to extract the symbolic links.
519 Capturing a WIM image should now be significantly faster in most cases
520 due to improved use of the operating system's cache and avoiding reading
521 files twice whenever possible.
523 The Windows build should now work on Windows XP.
525 The Windows build now supports capturing and restoring hidden,
526 compressed, sparse, and encrypted files.
528 The Windows build now supports capturing and applying WIM images from
529 filesystems other than NTFS (with some reduced functionality).
531 The Windows build now extracts short names correctly.
533 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
534 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
535 capture' and `wimlib-imagex apply'.
537 The performance of splitting and joining WIMs should be slightly
540 The LZX and XPRESS compression and decompression functions are now
541 exported from the library.
544 Improvements and bugfixes for the Windows build.
546 Added --strict-acls options.
548 Fixed the way that wimlib determines the order of images in the WIM.
551 Since wimlib can now be used on Windows, wimlib's implementation of
552 ImageX has been renamed to wimlib-imagex to avoid confusion with
553 Microsoft's implementation of ImageX, which would have the same file
554 name ("imagex.exe"). If you really don't like this you can pass the
555 --with-imagex-progname option to `configure' to choose a different name,
556 or even simply rename the binary yourself (but the former way will
557 configure the man pages to use the chosen name).
559 Various bugs fixed in the Windows build. Mainly to do with capturing
560 and restoring alternate data streams correctly in weird cases, and
561 requesting the correct privileges when opening files. Also added the
562 --noacls options to wimlib-imagex capture, append, and apply.
564 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
565 dynamically loaded, so this may make the library compatible with Windows
566 XP (however, there may still be other problems).
569 Added experimental support for native Windows builds. Binaries can be
570 downloaded from the SourceForge page.
572 --source-list option added to `imagex capture' and `imagex append'.
574 Better support for different character encodings.
577 Storing UNIX file owners, groups, and modes in WIM images is now
578 possible using `imagex capture' with the --unix-data flag.
580 Minor bug fixes and documentation fixes.
583 NTFS capture: Fixed capturing duplicate reparse points.
585 NTFS capture: Capture first unnamed stream if there are more than one
586 (print warning instead of error).
588 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
591 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
594 Update to work with ntfs-3g version 2013.1.13.
597 Fixed truncating file to shorter but non-zero length on read-write
600 Various code cleanups and minor documentation fixes.
603 LZX and XPRESS decompression have received some additional optimizations
604 and should now be even faster. (Although, they were already pretty
605 fast--- much faster than typical I/O speeds.)
607 Fixed a bug introduced in v1.2.1 that would cause a directory tree
608 containing hard links to be captured incorrectly in some cases.
611 By default, unmounting a read-write mounted WIM with 'imagex unmount
612 --commit' will now change the WIM in-place without needing to write the
613 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
616 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
617 for a response from the daemon servicing the mounted WIM. Instead,
618 every second 'imagex unmount' will check if the daemon is still alive,
619 and keep waiting if so, otherwise terminate with an error.
621 'imagex unmount --commit' on a read-write mounted WIM will now print
622 progress information regarding the writing of new or modified streams
623 the WIM, just like when capturing or appending a WIM.
625 A small change has been made to XPRESS compression and it should improve
626 the compression ratio slightly.
628 A change was made that may improve performance slightly when applying a
629 WIM image to a NTFS volume.
631 Microsoft has managed to introduce even more bugs into their software,
632 and now the WIMs for Windows 8 have incorrect (too low) reference counts
633 for some streams. This is unsafe because such streams can be removed
634 when they are in actuality still referenced in the WIM (perhaps by a
635 different image). wimlib will now work around this problem by fixing
636 the stream reference counts. This is only done when wimlib_delete_image() is
637 called ('imagex delete') or when wimlib_mount_image() is called with
638 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
639 requires reading the metadata for all images in the WIM, so this will
640 make these operations noticably slower on WIMs with multiple images.
642 Various other bugfixes.
645 Appending images to a WIM is now be done by default without re-building
646 the whole WIM. Use the --rebuild flag to get the old behavior (which
647 was to re-build the entire WIM when a new image is appended).
649 A new command `imagex optimize' is now available to manually re-build a
650 WIM that has wasted space due to repeated appends.
652 Progress information has been improved, and now arbitrary callback
653 functions can be used to show the progress of a WIM operation.
655 A possible bug with changing the bootable image of a WIM was fixed.
657 Some advisory locking is now done to prevent two processes from
658 modifying a WIM at the same time (but only in some cases). For example,
659 you cannot mount two images from a WIM read-write at the same time.
661 Some functions have been reorganized:
662 * wimlib_mount() renamed to wimlib_mount_image().
663 * wimlib_unmount() renamed to wimlib_unmount_image().
664 * wimlib_overwrite_xml_and_header() removed as
665 wimlib_overwrite() suffices now.
666 * wimlib_apply_image_to_ntfs_volume() removed as
667 wimlib_extract_image() suffices now.
668 * wimlib_add_image_from_ntfs_volume() removed as
669 * wimlib_add_image() suffices now.
671 Previously, the soname of libwim.so has been 0.0.0, despite many
672 interface changes. The soname is now updated to 1.0.0 and will now be
673 updated each release.
676 Resources will now be compressed using multiple threads by default.
677 (This applies to `imagex capture', `imagex append', and `imagex
680 Some performance improvements in mounted WIMs.
682 More progress information is shown when capturing a WIM.
685 Lots of minor fixes, code cleanups, and some documentation updates.
686 Nothing in particular is really noteworthy.
689 LZX and XPRESS compression improvements.
691 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
692 Link Bytes of the WIM.
695 Fixed bug when capturing NTFS file with multiple named data streams.
697 Internally, we are now using inode structures, even though these don't
698 appear literally in the WIM file. This simplifies some of the code
699 (mainly for WIM mounting) and likely fixed a few problems, although it
703 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
707 Enough changes to call it version 1.0.0!
709 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
710 to a NTFS volume, is now supported.
712 Hard links and symbolic links have much improved support. They are
713 supported for WIM capture, WIM application, and mounted WIMs (you can
714 even make them on read-write mounted WIMs).
716 Alternate data streams are now supported on mounted WIMs through an
717 xattr or a Windows-style stream interface. Also they are supported when
718 capturing a WIM from NTFS or applying a WIM to NTFS.
720 Split WIMs are better supported. You may now apply an image directly
721 from a split WIM, mount an image from a split WIM read-only, or export
722 an image from a split WIM.
724 Using a capture configuration file is now supported (but not fully yet).
726 SHA1 message digests are checked in more places, so we can make sure
727 applied and captured data is correct.
729 Man pages have been updated and consolidated.
732 Fixed segfault when unmounting read-only WIM.
735 Support for joining and splitting WIMs.
736 Also, security data is now preserved by default.
739 Can now build with older gcc and system headers, like on CentOS 5.
742 Fixed bug that made it impossible to overwrite files in read-write
746 Write byte-order mark before WIM XML data. (imagex.exe requires this to
