2 The LZX compression ratio has been slightly improved. The default mode,
3 LZX level 50, is now almost as good as the old LZX level 100, while
4 being nearly the same speed as before.
6 Decompression performance has been slightly improved.
8 Filenames are now always listed in NTFS collation order.
10 On UNIX-like systems, wimlib can now process Windows filenames that are
11 not valid Unicode due to the presence of unpaired surrogates.
13 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
14 addition of surrogate codepoints. Consequently, the environmental
15 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
16 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
18 wimlib no longer depends on iconv.
20 Reduced memory usage slightly.
22 When a WIM image is applied in NTFS-3G mode, security descriptors are
23 now created in NTFS v3.0 format when supported by the volume.
25 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
26 been removed. Users are advised to upgrade to a later version of
30 On UNIX, wimlib can now overwrite readonly files when extracting.
32 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
33 NTFS permissions") set on some existing directories after extraction.
35 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
36 driver is not loaded, wimlib can now correctly register a new WIM file
37 with the target volume when the target volume previously had had WIM
40 Added a new testing program.
42 Clarified the main license text and updated public domain dedications
43 for certain files to be more thorough.
46 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
48 Reduced memory usage when exporting large numbers of WIM images.
50 Non UTF-8 locales are now detected correctly.
52 Addressed compiler warnings and enabled "silent" make rules by default.
54 Windows-specific updates:
55 Fixed a bug where duplicate backslashes could be generated in
56 link targets when extracting symbolic links and junctions.
58 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
59 work if their full path contained a space.
61 Fixed bugs related to scanning SMB filesystems.
63 Added warning message about known issue with WindowsApps folder.
65 Added instructions for building from source on Windows.
67 VSS support is no longer marked "experimental".
69 Added missing license file for libdivsufsort-lite.
72 Added experimental support for Windows VSS (Volume Shadow Copy Service).
73 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
74 create and use a temporary VSS snapshot when capturing a WIM image.
76 Implemented setting of Windows-specific XML information, such as
77 architecture, system root, and version details. This information is now
78 automatically set in newly captured WIM images, when appropriate.
80 Improved performance of directory tree scans on Windows.
82 On Windows, to improve capture performance, wimlib now sometimes opens
83 files by inode number rather than by path. This is enabled for
84 wimcapture and wimappend, but for now other applications have to opt-in.
86 The progress messages printed by wimlib-imagex while writing WIM files
87 have been slightly tweaked.
89 Progress information for directory tree scans now counts all hard links.
90 Also, on Windows "\\?\" is no longer stripped from the current path.
92 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
93 'wiminfo'. This option lets you assign values to elements in a WIM
94 file's XML document by name.
96 The wimlib_get_image_property() and wimlib_set_image_property() API
97 functions now support numerically indexed elements.
99 Fixed a bug where, on Windows, wimlib would change the security
100 descriptor of the target directory of an extraction even when the
101 '--no-acls' option was specified.
104 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
105 some Microsoft software would not correctly recognize data in the
106 resulting filesystem.
108 Made some small improvements to the compression algorithms:
109 LZX compression ratio was slightly improved.
110 XPRESS compression ratio and speed was slightly improved.
111 LZMS compression speed was slightly improved.
113 Improved handling of WIM XML data. wimlib no longer drops unrecognized
114 elements when exporting images. In addition, two API functions were
115 added for better access to elements in the XML document:
116 wimlib_get_image_property() and wimlib_set_image_property().
118 Added support for (unsafe) in-place compaction of WIM files.
120 Improved performance of image export by reusing metadata resources
121 instead of always rebuilding and recompressing them.
123 Improved performance of wimlib_update_image() by delaying the update to
124 the WIM's XML document until a write is requested.
126 On Windows, the target of an extraction may now be a reparse point
127 (which will be dereferenced).
129 On Windows, wimlib now correctly restores non-Microsoft reparse points.
130 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
132 On Windows, wimlib now has improved performance when archiving files
133 from a filesystem backed by a WIM (a "WIMBoot" setup).
135 Several improvements to System Compression (compact mode) support:
137 wof.sys (or wofadk.sys) is now automatically attached to the
138 target volume if needed.
140 Compact-mode extractions now work correctly with wofadk.sys on
141 older versions of Windows.
143 For compatibility with the Windows bootloader, the requested
144 compression format now is overridden on certain files.
146 Other minor bugfixes.
149 This release primarily contains various minor bug fixes and
150 improvements, including:
152 Improved handling of deep directory structures.
154 Fixed a bug where on 32-bit systems, the library could enter an
155 infinite loop if a WIM file was malformed in a specific way.
157 Added a workaround for a case where libntfs-3g may report
158 duplicate streams in an NTFS file.
160 Windows symbolic links and junctions in mounted WIM images are
161 now automatically rewritten to be valid in the mounted location.
163 Reparse point fixes: correctly handle the "ReparseReserved"
164 field, and correctly handle "empty" (data-less) reparse points.
166 On Windows, wimlib now acquires SeManageVolumePrivilege, which
167 is needed to create externally backed files using the
170 Improved validation of filenames.
172 Improved LZMS decompression speed.
174 The configure script now honors alternate pkg-config settings.
176 Links have been updated to point to the new website.
178 In addition, experimental support has been added for compressing
179 extracted files using System Compression on Windows 10. This
180 functionality is available through the new '--compact' option to
181 'wimapply' and 'wimextract' as well as new library flags.
184 Fixed a bug in the LZX decompressor: malicious input data could cause
185 out of bounds writes to memory (since wimlib v1.2.2).
187 The output of the 'wiminfo' command now consolidates various boolean
188 flags (such as "Relative path junction") into a single line.
190 A file can now have both an unnamed data stream ("file contents") and a
191 reparse point stream. Such files can exist as a result of the use of
192 certain Windows features, such as offline storage, including "OneDrive".
193 wimlib will now store and restore both streams on Windows as well as in
194 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
196 On Windows, named data streams of encrypted files are no longer stored
197 twice in WIM archives.
199 On Windows, named data streams are now correctly extracted to existing
200 "readonly" directories. Before, an error would be reported.
202 On Windows, it is now possible to do a "WIMBoot mode" extraction with
203 non-standalone WIMs such as delta WIMs.
205 On Windows, when doing an extraction in "WIMBoot mode", files larger
206 than 4 gigabytes are now never extracted as externally backed. This
207 works around a bug in Microsoft's "WOF" driver.
209 The '--enable-verify-compression' configure option has been removed. If
210 you want to verify a WIM file, use the 'wimverify' program.
212 The way the "file count", "directory count", "total bytes", and "hard
213 link bytes" image statistics (stored in the WIM XML data) is calculated
214 has been slightly changed.
216 In mounted WIM images, the disk usage provided for each file (st_blocks)
217 is now the compressed size rather than the uncompressed size.
219 The performance of the NTFS-3g and Windows capture modes has been
222 On UNIX-like systems, symbolic links whose targets contain the backslash
223 character are now handled correctly (losslessly).
226 Improved the LZX compressor. It is now 15-20% faster than before and
227 provides a slightly better compression ratio.
229 Improved the LZMS compressor. It now provides a compression ratio
230 slightly better than WIMGAPI while still being faster and using slightly
233 The compression chunk size in solid resources, e.g. when capturing or
234 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
235 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
236 better compression ratio and is the same value that WIMGAPI uses. The
237 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
238 lower than WIMGAPI's memory usage, but if it is too much, it is still
239 possible to choose a lower value, e.g. with the '--solid-chunk-size'
240 option to wimlib-imagex.
242 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
243 accept the 'K', 'M', and 'G' suffixes.
245 Files are now sorted by name extension when creating a solid WIM file.
247 Fixed various issues related to capture/apply of EFS-encrypted files on
250 The file list printed by 'wimdir' is now sorted by the platform-specific
251 case sensitivity setting, rather than always case sensitively. This
252 also affects the library function wimlib_iterate_dir_tree().
254 On Windows, some error and warning messages have been improved.
257 The Windows binary distribution no longer contains third party DLLs.
258 These dependencies are instead compiled directly into the libwim DLL.
260 Added more fixes for wimlib on non-x86 architectures such as ARM.
262 Extracting files to a Windows PE in-memory filesystem no longer fails if
263 the target files do not yet exist.
265 Improved the performance of XPRESS compression and LZMS decompression.
267 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
268 It will automatically be faster on newer Intel and AMD processors.
270 Removed the --with-imagex-progname and --enable-more-assertions
274 Fix for very slow export from solid WIM / ESD files.
276 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
278 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
279 may use this to treat some types of errors as non-fatal.
281 The library now permits making in-memory changes to a WIMStruct backed
282 by a read-only WIM file.
284 Fixes for "WIMBoot" extraction mode (Windows only):
286 When not using the WOF driver, extraction no longer fails if the
287 disk containing the WIM file has too many partitions.
289 When matching patterns in [PrepopulateList], all hard links of
290 each file are now considered.
292 The system registry files are now automatically treated as being
293 in [PrepopulateList].
295 Added a hack to try to work around an intermittent bug in
296 Microsoft's WOF (Windows Overlay Filesystem) driver.
299 Made more improvements to the XPRESS, LZX, and LZMS compressors.
301 A number of improvements to the Windows port:
303 Fixes for setting short filenames.
305 Faster "WIMBoot" extraction.
307 Updated and slimmed down the dependent DLLs.
309 ACL inheritence bits are now restored.
311 Mandatory integrity labels are now backed up and restored.
313 Added a workaround for an issue where in rare cases, wimlib could create
314 a compressed data stream that could not be read correctly by Windows
315 after an extraction in "WIMBoot" mode.
318 Added file count progress data for
319 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
320 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
322 Added support for testing file exclusions via the user-provided
325 Some documentation improvements.
327 Made some clarifications to the license text in the COPYING file.
330 Made more improvements to the XPRESS, LZX, and LZMS compressors.
332 The default compression mode for wimcapture is now LZX compression in
333 its default mode, which is the same as '--compress=maximum'.
335 You can now specify an optional integer compression level to the
336 '--compress' option; e.g. '--compress=lzx:75'.
338 Made a minor change to the LZMS compressor and decompressor to fix an
339 incompatibility with the Microsoft implementation. In the unlikely
340 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
341 earlier and a checksum error is reported when extracting files from it
342 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
345 Added 'verify' subcommand to wimlib-imagex.
347 Notable library changes:
349 Custom compressor parameters have been removed from the library
350 in favor of the simpler level-based API.
352 Decompressor parameters have been removed entirely.
354 Library users can now specify a custom file for warning and
355 error messages to be sent to, rather than the default of
358 New progress messages:
359 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
360 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
362 New function: wimlib_verify_wim().
365 Improved compression, decompression, and extraction performance.
367 Improved compatibility with version 3584 WIM / ESD files:
368 - Add support for reading and writing multiple solid blocks per
369 archive, which WIMGAPI/DISM can create when appending an image.
370 - Correctly create solid blocks larger than 4 GiB.
372 'add' commands passed to wimupdate will now replace existing
373 nondirectory files by default. Use the --no-replace option to get the
376 The license for the library now contains an exception that allows using
377 it under the LGPL. See the COPYING file for details.
379 In reparse-point fixup mode (the default for capture), symbolic links
380 and junctions that point outside the tree being captured are no longer
381 excluded from capture.
383 Added support for "WIMBoot" capture and extraction. See the
384 documentation for the new '--wimboot' option to wimcapture and wimapply
385 for more information.
387 On UNIX-like systems, you can now backup and restore device nodes, named
388 pipes, and sockets. In addition, 32-bit user and group IDs are now
391 The way that UNIX data is stored in WIM files has been changed. If you
392 captured any WIMs with the --unix-data option, to upgrade them you'll
393 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
394 re-capture them with --unix-data using this version.
396 wimlib now understands tagged metadata items, such as object IDs, that
397 can be stored in WIM directory entries.
399 Removed the --hardlink and --symlink options to wimapply, since I don't
400 think they are too useful and they got in the way of improving the code.
402 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
404 The 'mkwinpeimg' script now supports writing the ISO image to standard
407 The <ARCH> element in WIM XML data is now exported correctly.
409 On Windows, sparse file attributes are no longer set on extracted files.
410 Oddly enough, this actually saves disk space in some cases.
412 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
413 supported. Mounting WIM images now always requires extended attribute
414 support. Use --without-fuse to disable support for mounting WIM images;
415 this will also disable the need for extended attribute support.
417 Configuring with --enable-ssse3-sha1 now works correctly.
419 The shared library version has been bumped up. The main
420 incompatibilities are:
422 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
423 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
426 - User-provided progress functions are now registered using a
427 separate function, wimlib_register_progress_function(). The
428 'progress_func' argument to many functions no longer exists.
430 - The return value from user-provided progress functions is now
433 - A context argument has been added to the prototype of
434 user-provided progress functions.
436 - 'struct wimlib_capture_config' has been removed. The library
437 now takes the path to the configuration file directly. This
438 affects wimlib_add_image(), wimlib_add_image_multisource(),
439 and wimlib_update_image(). However, a NULL value passed in
440 the argument retains the same meaning.
442 - Removed deprecated functions: some (de)compression functions,
443 wimlib_extract_files(), and wimlib_print_metadata().
445 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
446 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
447 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
449 - Removed some progress messages:
450 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
451 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
452 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
455 - Removed some error codes. Numbering stays the same.
457 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
458 WIMLIB_UNMOUNT_FLAG_FORCE.
460 - WIM paths passed to progress functions now have a leading
464 Case-insensitive comparisons of strings (e.g. filenames) containing
465 UTF-16 codepoints above 32767 are now done correctly.
467 Fixed build failure on Mac OS X.
469 wimunmount now provides the '--new-image' option to cause changes to a
470 read-write mounted image to be committed as a new image rather than as
471 an update of the mounted image. (The corresponding new library flag is
472 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
474 The LZMS ("recovery") compression chunk size, or "dictionary size", may
475 now be up to 1 GiB (1,073,741,824 bytes).
477 The performance of LZX ("maximum") and LZMS ("recovery") compression
478 with large chunk sizes has been slightly improved.
481 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
482 decompressed correctly.
484 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
485 occurred in an unlikely case, and due to validity checks it did not
486 affect successfully created archives.
488 Fixed a minor compatibility issue with the LZMS compressor and
489 decompressor. This is *not* the default compression type and was only
490 introduced in v1.6.0. In the unlikely event that you created an
491 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
492 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
495 Memory usage for LZMS and LZX compression has been decreased.
497 wimextract now allows wildcard characters in paths specified on the
498 command line. Also, the '--strict-wildcards' option has been removed
499 and replaced with the inverse option '--nullglob'. See the
500 documentation for wimextract for more details and changes.
502 The wimlib_extract_files() function is now considered deprecated in
503 favor of wimlib_extract_paths().
505 Fixed more permissions problems when extracting files on Windows.
507 A new '--no-attributes' option has been added to wimapply and
508 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
510 The default chunk size is now set correctly when changing the
511 compression type of a WIM, for example with 'wimoptimize'.
513 The '--metadata' option to wiminfo has been replaced with the
514 '--detailed' option to wimdir.
516 In relevant wimlib-imagex commands, '--solid' may now be used as an
517 alias for '--pack-streams'.
520 Support for extracting and updating the new version 3584 WIMs has been
521 added. These WIMs typically pack many streams ("files") together into a
522 single compressed resource, thereby saving space. This degrades the
523 performance of random access (such as that which occurs on a mounted
524 image), but optimizations have been implemented for extraction. These
525 new WIM files also typically use a new compression format (LZMS), which
526 is similar to LZMA and can offer a better compression ratio than LZX.
527 These new WIM files can be created using `wimcapture' with
528 the '--compress=lzms --pack-streams' options. Note: this new WIM format
529 is used by the Windows 8 web downloader, but important segments of the
530 raw '.esd' files are encrypted, so wimlib will not be able to extract
531 such files until they are first decrypted.
533 wimlib now supports extracting files and directories from a WIM image
534 based on a "listfile" that itself contains the list of paths to extract.
535 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
536 and for the library itself, the new APIs are wimlib_extract_pathlist()
537 and wimlib_extract_paths(). Path globs containing wildcard characters
540 For searching WIM files, wimlib now has configurable case sensitivity.
541 The default on Windows is still case-insensitive and the default on
542 UNIX-like systems is still case-sensitive, but this can be overridden
543 on either platform through flags to wimlib_global_init(). For
544 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
545 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
548 Support for compression chunk sizes greater than the default of 32768
549 bytes has been added. A larger chunk size typically results in a better
550 compression ratio. However, the MS implementation is seemingly not
551 compatible with all chunk sizes, especially for LZX compression, so the
552 defaults remain unchanged, with the exception of the new LZMS-compressed
553 WIMs, which use a larger chunk size by default.
555 The compression/decompression API exported by wimlib has been changed.
556 Now one set of functions handles all supported compression formats.
558 `wimcapture' and `wimappend' will now display the progress of scanning
559 the directory tree to capture, in addition to the progress of writing
560 data to the WIM. The '--verbose' option no longer does anything. The
561 library API change for this is the addition of several members to
562 `struct wimlib_progress_info_scan' available to progress callbacks.
564 `mkwinpeimg' now correctly handles the '--start-script' option when the
565 start script is not in the working directory.
567 Sequential extraction, previously requested by using
568 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
569 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
570 behavior (extract in file order).
573 The new LZX compressor added in v1.5.2 has been improved and is now
574 enabled by default, except when `wimcapture' or `wimappend' is run
575 *without* the '--compress' option, in which case the faster LZX
576 compressor is used (the same as before). This behavior is reasonably
577 consistent with ImageX which actually uses "fast" (XPRESS) compression
578 by default. In those cases, use '--compress=maximum' to explicitly
579 capture a WIM image using the new (slower but better) LZX compressor.
581 The '--compress-slow' option still exists to `wimlib-imagex optimize',
582 but its new behavior is to tweak the new LZX compressor even more to
583 produce an even better compression ratio at the cost of more time spent
586 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
587 which recompresses the WIM file using the specified compression TYPE.
588 The new library API function used for this is
589 wimlib_set_output_compression_type().
591 Added the wimlib_get_xml_data() function to allow library clients to
592 easily retrieve the raw XML data from a WIM file if needed.
594 Fixed a bug that could cause an error code to be incorrectly returned
595 when writing XML data containing a <WINDOWS> element.
597 Mounted WIM images will now correctly show the default file stream even
598 if appears in the alternate data stream entries of the corresponding WIM
602 Added a new experimental LZX compressor which can be enabled by passing
603 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
604 optimize'. (The latter is only applicable if the WIM is already
605 LZX-compressed and the '--recompress' option is also given.) The
606 experimental compressor is much slower but compresses the data slightly
607 more --- currently usually to within a fraction of a percent of the
608 results from WIMGAPI/ImageX.
610 A workaround has been added for compatibility with versions of WinPE
611 that interpret alternate data stream entries in the boot WIM
614 An alignment bug that caused a crash in the LZX decompressor on some
617 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
618 the WIM header when restoring the previous state of a WIM it failed to
621 Added a workaround to avoid an access denied error on Windows when
622 replacing a WIM file that another process has opened.
625 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
626 needed to be handled.
628 A bug in the interpretation of negative IMAGE indices in the
629 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
630 `wimlib-imagex append' has been fixed.
632 A workaround has been added to successfully apply security descriptors
633 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
634 2013.1.13 or earlier.
636 `wimlib-imagex capture' can now accept the '--delta-from' option
640 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
641 to standard output and applying images from standard input, but they are
642 not compatible with Microsoft's software and are not created by default.
643 See the documentation for --pipable flag of `wimlib-imagex capture' for
646 To better support incremental backups, added support for declaring an
647 image as a modified form of another image. See the documentation for
648 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
651 Added supported for "delta" WIMs. See the documentation for the
652 '--delta-from' option of `wimlib-imagex capture'.
654 The library support for managing split WIMs has been changed to support
655 other arrangements, such as delta WIMs, and be easier to use. This
656 change is visible in `wimlib-imagex', which also can now accept the
657 '--ref' option multiple times, and also now supports "delta" WIMs as
660 wimlib now preserves WIM integrity tables by default, even if
661 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
662 behavior of `wimlib-imagex' whenever the WIM being operated on contains
663 an integrity table and the '--check' option is not specified.
665 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
666 (when --compress is not specified). This provides the best compression
667 ratio by default, which is usually what is desired, at a cost of some
670 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
671 is the command as in `wimlib-imagex COMMAND'; for example, it can be
672 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
673 appropriate hard links are created in UNIX installations of
674 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
675 batch files that emulate this behavior are generated.
677 Security descriptors are now extracted correctly on Windows.
679 Fixed archiving DOS names in NTFS-3g capture mode.
681 The extraction code has been rewritten and it will now be easier to
682 support new features on all supported backends (currently Win32, UNIX,
683 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
684 now supported on all backends, not just UNIX.
686 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
687 than the WAIK itself.
689 wimlib_global_init() now, by default, attempts to acquire additional
690 privileges on Windows, so library clients need not do this.
692 This update bumps the shared library version number up to 9, since it is
693 not binary compatibible with previous releases.
696 Fixed bug in `wimlib-imagex export' that made it impossible to export an
697 image from a WIM that is readonly at the filesystem level.
699 Return error code rather than segfaulting when trying to list files from
700 a non-first part of a split WIM.
702 Joining a WIM will now preserve the RP_FIX and READONLY flags.
705 On Windows, paths given to wimlib-imagex are now treated case
708 Improved behavior regarding invalid filenames; in particular, on
709 Windows, wimlib-imagex will, when extracting, now omit (with an option
710 to override this default) filenames differing only in case, or filenames
711 containing characters not valid on Windows.
713 On Windows, wimlib now supports capturing and extracting long paths
714 (longer than the so-called MAX_PATH).
716 On Windows, `wimlib-imagex update' now acquires proper privileges when
717 running as an Administrator.
719 `wimlib-imagex update' will now complain if no image is specified when
720 trying to update a multi-image WIM.
722 `wimlib-imagex update' now supports specifying a single update command
723 directly on the command line using the --command option.
725 wimlib-imagex will now choose different units for progress messages,
726 depending on the amount of data that needs to be processed.
728 `wimlib-imagex append' will now generate a unique WIM image name if no
729 name is specified and the defaulted name already exists in the WIM.
731 wimlib now allows you to create unnamed WIM images, which can then only
732 be referred to by index.
734 wimlib now allows you to explicitly declare you want write access to a
735 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
738 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
741 Progress callbacks have been added to wimlib's wimlib_update_image()
744 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
745 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
748 NTFS-3g capture now only warns about two conditions previously treated
751 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
754 wimlib now correctly detects and returns an error when reading a WIM
755 image with a cyclic directory structure. (Fun fact: such a WIM will
756 crash Microsoft's software.)
759 Added new "extract" and "update" subcommands to wimlib-imagex, along
760 with associated APIs in the library. These commands are intended mainly
761 for Windows use but can be used on UNIX as well.
763 Many documentation improvements.
765 Fixed a bug in the Windows build where relative symbolic links were not
766 captured in reparse-point fixup mode.
768 Fixed a bug in the Windows build where file handles were left open to
769 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
771 Fixed a bug in the Windows build of wimlib-imagex where globbing
772 split-WIM parts could cause the program to crash.
774 Fixed a bug where the creation time of WIM images would be shown instead
775 of the last modification time.
777 With the Windows build it is now possible to restore a WIM containing
778 symbolic links as a non-Administrator; however you will receive warnings
779 about not being able to extract the symbolic links.
782 Capturing a WIM image should now be significantly faster in most cases
783 due to improved use of the operating system's cache and avoiding reading
784 files twice whenever possible.
786 The Windows build should now work on Windows XP.
788 The Windows build now supports capturing and restoring hidden,
789 compressed, sparse, and encrypted files.
791 The Windows build now supports capturing and applying WIM images from
792 filesystems other than NTFS (with some reduced functionality).
794 The Windows build now extracts short names correctly.
796 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
797 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
798 capture' and `wimlib-imagex apply'.
800 The performance of splitting and joining WIMs should be slightly
803 The LZX and XPRESS compression and decompression functions are now
804 exported from the library.
807 Improvements and bugfixes for the Windows build.
809 Added --strict-acls options.
811 Fixed the way that wimlib determines the order of images in the WIM.
814 Since wimlib can now be used on Windows, wimlib's implementation of
815 ImageX has been renamed to wimlib-imagex to avoid confusion with
816 Microsoft's implementation of ImageX, which would have the same file
817 name ("imagex.exe"). If you really don't like this you can pass the
818 --with-imagex-progname option to `configure' to choose a different name,
819 or even simply rename the binary yourself (but the former way will
820 configure the man pages to use the chosen name).
822 Various bugs fixed in the Windows build. Mainly to do with capturing
823 and restoring alternate data streams correctly in weird cases, and
824 requesting the correct privileges when opening files. Also added the
825 --noacls options to wimlib-imagex capture, append, and apply.
827 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
828 dynamically loaded, so this may make the library compatible with Windows
829 XP (however, there may still be other problems).
832 Added experimental support for native Windows builds. Binaries can be
833 downloaded from the SourceForge page.
835 --source-list option added to `imagex capture' and `imagex append'.
837 Better support for different character encodings.
840 Storing UNIX file owners, groups, and modes in WIM images is now
841 possible using `imagex capture' with the --unix-data flag.
843 Minor bug fixes and documentation fixes.
846 NTFS capture: Fixed capturing duplicate reparse points.
848 NTFS capture: Capture first unnamed stream if there are more than one
849 (print warning instead of error).
851 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
854 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
857 Update to work with ntfs-3g version 2013.1.13.
860 Fixed truncating file to shorter but non-zero length on read-write
863 Various code cleanups and minor documentation fixes.
866 LZX and XPRESS decompression have received some additional optimizations
867 and should now be even faster. (Although, they were already pretty
868 fast--- much faster than typical I/O speeds.)
870 Fixed a bug introduced in v1.2.1 that would cause a directory tree
871 containing hard links to be captured incorrectly in some cases.
874 By default, unmounting a read-write mounted WIM with 'imagex unmount
875 --commit' will now change the WIM in-place without needing to write the
876 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
879 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
880 for a response from the daemon servicing the mounted WIM. Instead,
881 every second 'imagex unmount' will check if the daemon is still alive,
882 and keep waiting if so, otherwise terminate with an error.
884 'imagex unmount --commit' on a read-write mounted WIM will now print
885 progress information regarding the writing of new or modified streams
886 the WIM, just like when capturing or appending a WIM.
888 A small change has been made to XPRESS compression and it should improve
889 the compression ratio slightly.
891 A change was made that may improve performance slightly when applying a
892 WIM image to a NTFS volume.
894 Microsoft has managed to introduce even more bugs into their software,
895 and now the WIMs for Windows 8 have incorrect (too low) reference counts
896 for some streams. This is unsafe because such streams can be removed
897 when they are in actuality still referenced in the WIM (perhaps by a
898 different image). wimlib will now work around this problem by fixing
899 the stream reference counts. This is only done when wimlib_delete_image() is
900 called ('imagex delete') or when wimlib_mount_image() is called with
901 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
902 requires reading the metadata for all images in the WIM, so this will
903 make these operations noticably slower on WIMs with multiple images.
905 Various other bugfixes.
908 Appending images to a WIM is now be done by default without re-building
909 the whole WIM. Use the --rebuild flag to get the old behavior (which
910 was to re-build the entire WIM when a new image is appended).
912 A new command `imagex optimize' is now available to manually re-build a
913 WIM that has wasted space due to repeated appends.
915 Progress information has been improved, and now arbitrary callback
916 functions can be used to show the progress of a WIM operation.
918 A possible bug with changing the bootable image of a WIM was fixed.
920 Some advisory locking is now done to prevent two processes from
921 modifying a WIM at the same time (but only in some cases). For example,
922 you cannot mount two images from a WIM read-write at the same time.
924 Some functions have been reorganized:
925 * wimlib_mount() renamed to wimlib_mount_image().
926 * wimlib_unmount() renamed to wimlib_unmount_image().
927 * wimlib_overwrite_xml_and_header() removed as
928 wimlib_overwrite() suffices now.
929 * wimlib_apply_image_to_ntfs_volume() removed as
930 wimlib_extract_image() suffices now.
931 * wimlib_add_image_from_ntfs_volume() removed as
932 * wimlib_add_image() suffices now.
934 Previously, the soname of libwim.so has been 0.0.0, despite many
935 interface changes. The soname is now updated to 1.0.0 and will now be
936 updated each release.
939 Resources will now be compressed using multiple threads by default.
940 (This applies to `imagex capture', `imagex append', and `imagex
943 Some performance improvements in mounted WIMs.
945 More progress information is shown when capturing a WIM.
948 Lots of minor fixes, code cleanups, and some documentation updates.
949 Nothing in particular is really noteworthy.
952 LZX and XPRESS compression improvements.
954 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
955 Link Bytes of the WIM.
958 Fixed bug when capturing NTFS file with multiple named data streams.
960 Internally, we are now using inode structures, even though these don't
961 appear literally in the WIM file. This simplifies some of the code
962 (mainly for WIM mounting) and likely fixed a few problems, although it
966 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
970 Enough changes to call it version 1.0.0!
972 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
973 to a NTFS volume, is now supported.
975 Hard links and symbolic links have much improved support. They are
976 supported for WIM capture, WIM application, and mounted WIMs (you can
977 even make them on read-write mounted WIMs).
979 Alternate data streams are now supported on mounted WIMs through an
980 xattr or a Windows-style stream interface. Also they are supported when
981 capturing a WIM from NTFS or applying a WIM to NTFS.
983 Split WIMs are better supported. You may now apply an image directly
984 from a split WIM, mount an image from a split WIM read-only, or export
985 an image from a split WIM.
987 Using a capture configuration file is now supported (but not fully yet).
989 SHA1 message digests are checked in more places, so we can make sure
990 applied and captured data is correct.
992 Man pages have been updated and consolidated.
995 Fixed segfault when unmounting read-only WIM.
998 Support for joining and splitting WIMs.
999 Also, security data is now preserved by default.
1002 Can now build with older gcc and system headers, like on CentOS 5.
1005 Fixed bug that made it impossible to overwrite files in read-write
1009 Write byte-order mark before WIM XML data. (imagex.exe requires this to
