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 On UNIX-like systems, wimlib can now process Windows filenames that are
7 not valid Unicode due to the presence of unpaired surrogates.
9 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
10 addition of surrogate codepoints. Consequently, the environmental
11 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
12 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
14 wimlib no longer depends on iconv.
16 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
17 been removed. Users are advised to upgrade to a later version of
21 On UNIX, wimlib can now overwrite readonly files when extracting.
23 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
24 NTFS permissions") set on some existing directories after extraction.
26 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
27 driver is not loaded, wimlib can now correctly register a new WIM file
28 with the target volume when the target volume previously had had WIM
31 Added a new testing program.
33 Clarified the main license text and updated public domain dedications
34 for certain files to be more thorough.
37 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
39 Reduced memory usage when exporting large numbers of WIM images.
41 Non UTF-8 locales are now detected correctly.
43 Addressed compiler warnings and enabled "silent" make rules by default.
45 Windows-specific updates:
46 Fixed a bug where duplicate backslashes could be generated in
47 link targets when extracting symbolic links and junctions.
49 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
50 work if their full path contained a space.
52 Fixed bugs related to scanning SMB filesystems.
54 Added warning message about known issue with WindowsApps folder.
56 Added instructions for building from source on Windows.
58 VSS support is no longer marked "experimental".
60 Added missing license file for libdivsufsort-lite.
63 Added experimental support for Windows VSS (Volume Shadow Copy Service).
64 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
65 create and use a temporary VSS snapshot when capturing a WIM image.
67 Implemented setting of Windows-specific XML information, such as
68 architecture, system root, and version details. This information is now
69 automatically set in newly captured WIM images, when appropriate.
71 Improved performance of directory tree scans on Windows.
73 On Windows, to improve capture performance, wimlib now sometimes opens
74 files by inode number rather than by path. This is enabled for
75 wimcapture and wimappend, but for now other applications have to opt-in.
77 The progress messages printed by wimlib-imagex while writing WIM files
78 have been slightly tweaked.
80 Progress information for directory tree scans now counts all hard links.
81 Also, on Windows "\\?\" is no longer stripped from the current path.
83 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
84 'wiminfo'. This option lets you assign values to elements in a WIM
85 file's XML document by name.
87 The wimlib_get_image_property() and wimlib_set_image_property() API
88 functions now support numerically indexed elements.
90 Fixed a bug where, on Windows, wimlib would change the security
91 descriptor of the target directory of an extraction even when the
92 '--no-acls' option was specified.
95 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
96 some Microsoft software would not correctly recognize data in the
99 Made some small improvements to the compression algorithms:
100 LZX compression ratio was slightly improved.
101 XPRESS compression ratio and speed was slightly improved.
102 LZMS compression speed was slightly improved.
104 Improved handling of WIM XML data. wimlib no longer drops unrecognized
105 elements when exporting images. In addition, two API functions were
106 added for better access to elements in the XML document:
107 wimlib_get_image_property() and wimlib_set_image_property().
109 Added support for (unsafe) in-place compaction of WIM files.
111 Improved performance of image export by reusing metadata resources
112 instead of always rebuilding and recompressing them.
114 Improved performance of wimlib_update_image() by delaying the update to
115 the WIM's XML document until a write is requested.
117 On Windows, the target of an extraction may now be a reparse point
118 (which will be dereferenced).
120 On Windows, wimlib now correctly restores non-Microsoft reparse points.
121 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
123 On Windows, wimlib now has improved performance when archiving files
124 from a filesystem backed by a WIM (a "WIMBoot" setup).
126 Several improvements to System Compression (compact mode) support:
128 wof.sys (or wofadk.sys) is now automatically attached to the
129 target volume if needed.
131 Compact-mode extractions now work correctly with wofadk.sys on
132 older versions of Windows.
134 For compatibility with the Windows bootloader, the requested
135 compression format now is overridden on certain files.
137 Other minor bugfixes.
140 This release primarily contains various minor bug fixes and
141 improvements, including:
143 Improved handling of deep directory structures.
145 Fixed a bug where on 32-bit systems, the library could enter an
146 infinite loop if a WIM file was malformed in a specific way.
148 Added a workaround for a case where libntfs-3g may report
149 duplicate streams in an NTFS file.
151 Windows symbolic links and junctions in mounted WIM images are
152 now automatically rewritten to be valid in the mounted location.
154 Reparse point fixes: correctly handle the "ReparseReserved"
155 field, and correctly handle "empty" (data-less) reparse points.
157 On Windows, wimlib now acquires SeManageVolumePrivilege, which
158 is needed to create externally backed files using the
161 Improved validation of filenames.
163 Improved LZMS decompression speed.
165 The configure script now honors alternate pkg-config settings.
167 Links have been updated to point to the new website.
169 In addition, experimental support has been added for compressing
170 extracted files using System Compression on Windows 10. This
171 functionality is available through the new '--compact' option to
172 'wimapply' and 'wimextract' as well as new library flags.
175 Fixed a bug in the LZX decompressor: malicious input data could cause
176 out of bounds writes to memory (since wimlib v1.2.2).
178 The output of the 'wiminfo' command now consolidates various boolean
179 flags (such as "Relative path junction") into a single line.
181 A file can now have both an unnamed data stream ("file contents") and a
182 reparse point stream. Such files can exist as a result of the use of
183 certain Windows features, such as offline storage, including "OneDrive".
184 wimlib will now store and restore both streams on Windows as well as in
185 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
187 On Windows, named data streams of encrypted files are no longer stored
188 twice in WIM archives.
190 On Windows, named data streams are now correctly extracted to existing
191 "readonly" directories. Before, an error would be reported.
193 On Windows, it is now possible to do a "WIMBoot mode" extraction with
194 non-standalone WIMs such as delta WIMs.
196 On Windows, when doing an extraction in "WIMBoot mode", files larger
197 than 4 gigabytes are now never extracted as externally backed. This
198 works around a bug in Microsoft's "WOF" driver.
200 The '--enable-verify-compression' configure option has been removed. If
201 you want to verify a WIM file, use the 'wimverify' program.
203 The way the "file count", "directory count", "total bytes", and "hard
204 link bytes" image statistics (stored in the WIM XML data) is calculated
205 has been slightly changed.
207 In mounted WIM images, the disk usage provided for each file (st_blocks)
208 is now the compressed size rather than the uncompressed size.
210 The performance of the NTFS-3g and Windows capture modes has been
213 On UNIX-like systems, symbolic links whose targets contain the backslash
214 character are now handled correctly (losslessly).
217 Improved the LZX compressor. It is now 15-20% faster than before and
218 provides a slightly better compression ratio.
220 Improved the LZMS compressor. It now provides a compression ratio
221 slightly better than WIMGAPI while still being faster and using slightly
224 The compression chunk size in solid resources, e.g. when capturing or
225 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
226 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
227 better compression ratio and is the same value that WIMGAPI uses. The
228 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
229 lower than WIMGAPI's memory usage, but if it is too much, it is still
230 possible to choose a lower value, e.g. with the '--solid-chunk-size'
231 option to wimlib-imagex.
233 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
234 accept the 'K', 'M', and 'G' suffixes.
236 Files are now sorted by name extension when creating a solid WIM file.
238 Fixed various issues related to capture/apply of EFS-encrypted files on
241 The file list printed by 'wimdir' is now sorted by the platform-specific
242 case sensitivity setting, rather than always case sensitively. This
243 also affects the library function wimlib_iterate_dir_tree().
245 On Windows, some error and warning messages have been improved.
248 The Windows binary distribution no longer contains third party DLLs.
249 These dependencies are instead compiled directly into the libwim DLL.
251 Added more fixes for wimlib on non-x86 architectures such as ARM.
253 Extracting files to a Windows PE in-memory filesystem no longer fails if
254 the target files do not yet exist.
256 Improved the performance of XPRESS compression and LZMS decompression.
258 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
259 It will automatically be faster on newer Intel and AMD processors.
261 Removed the --with-imagex-progname and --enable-more-assertions
265 Fix for very slow export from solid WIM / ESD files.
267 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
269 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
270 may use this to treat some types of errors as non-fatal.
272 The library now permits making in-memory changes to a WIMStruct backed
273 by a read-only WIM file.
275 Fixes for "WIMBoot" extraction mode (Windows only):
277 When not using the WOF driver, extraction no longer fails if the
278 disk containing the WIM file has too many partitions.
280 When matching patterns in [PrepopulateList], all hard links of
281 each file are now considered.
283 The system registry files are now automatically treated as being
284 in [PrepopulateList].
286 Added a hack to try to work around an intermittent bug in
287 Microsoft's WOF (Windows Overlay Filesystem) driver.
290 Made more improvements to the XPRESS, LZX, and LZMS compressors.
292 A number of improvements to the Windows port:
294 Fixes for setting short filenames.
296 Faster "WIMBoot" extraction.
298 Updated and slimmed down the dependent DLLs.
300 ACL inheritence bits are now restored.
302 Mandatory integrity labels are now backed up and restored.
304 Added a workaround for an issue where in rare cases, wimlib could create
305 a compressed data stream that could not be read correctly by Windows
306 after an extraction in "WIMBoot" mode.
309 Added file count progress data for
310 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
311 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
313 Added support for testing file exclusions via the user-provided
316 Some documentation improvements.
318 Made some clarifications to the license text in the COPYING file.
321 Made more improvements to the XPRESS, LZX, and LZMS compressors.
323 The default compression mode for wimcapture is now LZX compression in
324 its default mode, which is the same as '--compress=maximum'.
326 You can now specify an optional integer compression level to the
327 '--compress' option; e.g. '--compress=lzx:75'.
329 Made a minor change to the LZMS compressor and decompressor to fix an
330 incompatibility with the Microsoft implementation. In the unlikely
331 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
332 earlier and a checksum error is reported when extracting files from it
333 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
336 Added 'verify' subcommand to wimlib-imagex.
338 Notable library changes:
340 Custom compressor parameters have been removed from the library
341 in favor of the simpler level-based API.
343 Decompressor parameters have been removed entirely.
345 Library users can now specify a custom file for warning and
346 error messages to be sent to, rather than the default of
349 New progress messages:
350 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
351 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
353 New function: wimlib_verify_wim().
356 Improved compression, decompression, and extraction performance.
358 Improved compatibility with version 3584 WIM / ESD files:
359 - Add support for reading and writing multiple solid blocks per
360 archive, which WIMGAPI/DISM can create when appending an image.
361 - Correctly create solid blocks larger than 4 GiB.
363 'add' commands passed to wimupdate will now replace existing
364 nondirectory files by default. Use the --no-replace option to get the
367 The license for the library now contains an exception that allows using
368 it under the LGPL. See the COPYING file for details.
370 In reparse-point fixup mode (the default for capture), symbolic links
371 and junctions that point outside the tree being captured are no longer
372 excluded from capture.
374 Added support for "WIMBoot" capture and extraction. See the
375 documentation for the new '--wimboot' option to wimcapture and wimapply
376 for more information.
378 On UNIX-like systems, you can now backup and restore device nodes, named
379 pipes, and sockets. In addition, 32-bit user and group IDs are now
382 The way that UNIX data is stored in WIM files has been changed. If you
383 captured any WIMs with the --unix-data option, to upgrade them you'll
384 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
385 re-capture them with --unix-data using this version.
387 wimlib now understands tagged metadata items, such as object IDs, that
388 can be stored in WIM directory entries.
390 Removed the --hardlink and --symlink options to wimapply, since I don't
391 think they are too useful and they got in the way of improving the code.
393 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
395 The 'mkwinpeimg' script now supports writing the ISO image to standard
398 The <ARCH> element in WIM XML data is now exported correctly.
400 On Windows, sparse file attributes are no longer set on extracted files.
401 Oddly enough, this actually saves disk space in some cases.
403 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
404 supported. Mounting WIM images now always requires extended attribute
405 support. Use --without-fuse to disable support for mounting WIM images;
406 this will also disable the need for extended attribute support.
408 Configuring with --enable-ssse3-sha1 now works correctly.
410 The shared library version has been bumped up. The main
411 incompatibilities are:
413 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
414 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
417 - User-provided progress functions are now registered using a
418 separate function, wimlib_register_progress_function(). The
419 'progress_func' argument to many functions no longer exists.
421 - The return value from user-provided progress functions is now
424 - A context argument has been added to the prototype of
425 user-provided progress functions.
427 - 'struct wimlib_capture_config' has been removed. The library
428 now takes the path to the configuration file directly. This
429 affects wimlib_add_image(), wimlib_add_image_multisource(),
430 and wimlib_update_image(). However, a NULL value passed in
431 the argument retains the same meaning.
433 - Removed deprecated functions: some (de)compression functions,
434 wimlib_extract_files(), and wimlib_print_metadata().
436 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
437 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
438 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
440 - Removed some progress messages:
441 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
442 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
443 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
446 - Removed some error codes. Numbering stays the same.
448 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
449 WIMLIB_UNMOUNT_FLAG_FORCE.
451 - WIM paths passed to progress functions now have a leading
455 Case-insensitive comparisons of strings (e.g. filenames) containing
456 UTF-16 codepoints above 32767 are now done correctly.
458 Fixed build failure on Mac OS X.
460 wimunmount now provides the '--new-image' option to cause changes to a
461 read-write mounted image to be committed as a new image rather than as
462 an update of the mounted image. (The corresponding new library flag is
463 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
465 The LZMS ("recovery") compression chunk size, or "dictionary size", may
466 now be up to 1 GiB (1,073,741,824 bytes).
468 The performance of LZX ("maximum") and LZMS ("recovery") compression
469 with large chunk sizes has been slightly improved.
472 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
473 decompressed correctly.
475 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
476 occurred in an unlikely case, and due to validity checks it did not
477 affect successfully created archives.
479 Fixed a minor compatibility issue with the LZMS compressor and
480 decompressor. This is *not* the default compression type and was only
481 introduced in v1.6.0. In the unlikely event that you created an
482 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
483 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
486 Memory usage for LZMS and LZX compression has been decreased.
488 wimextract now allows wildcard characters in paths specified on the
489 command line. Also, the '--strict-wildcards' option has been removed
490 and replaced with the inverse option '--nullglob'. See the
491 documentation for wimextract for more details and changes.
493 The wimlib_extract_files() function is now considered deprecated in
494 favor of wimlib_extract_paths().
496 Fixed more permissions problems when extracting files on Windows.
498 A new '--no-attributes' option has been added to wimapply and
499 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
501 The default chunk size is now set correctly when changing the
502 compression type of a WIM, for example with 'wimoptimize'.
504 The '--metadata' option to wiminfo has been replaced with the
505 '--detailed' option to wimdir.
507 In relevant wimlib-imagex commands, '--solid' may now be used as an
508 alias for '--pack-streams'.
511 Support for extracting and updating the new version 3584 WIMs has been
512 added. These WIMs typically pack many streams ("files") together into a
513 single compressed resource, thereby saving space. This degrades the
514 performance of random access (such as that which occurs on a mounted
515 image), but optimizations have been implemented for extraction. These
516 new WIM files also typically use a new compression format (LZMS), which
517 is similar to LZMA and can offer a better compression ratio than LZX.
518 These new WIM files can be created using `wimcapture' with
519 the '--compress=lzms --pack-streams' options. Note: this new WIM format
520 is used by the Windows 8 web downloader, but important segments of the
521 raw '.esd' files are encrypted, so wimlib will not be able to extract
522 such files until they are first decrypted.
524 wimlib now supports extracting files and directories from a WIM image
525 based on a "listfile" that itself contains the list of paths to extract.
526 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
527 and for the library itself, the new APIs are wimlib_extract_pathlist()
528 and wimlib_extract_paths(). Path globs containing wildcard characters
531 For searching WIM files, wimlib now has configurable case sensitivity.
532 The default on Windows is still case-insensitive and the default on
533 UNIX-like systems is still case-sensitive, but this can be overridden
534 on either platform through flags to wimlib_global_init(). For
535 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
536 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
539 Support for compression chunk sizes greater than the default of 32768
540 bytes has been added. A larger chunk size typically results in a better
541 compression ratio. However, the MS implementation is seemingly not
542 compatible with all chunk sizes, especially for LZX compression, so the
543 defaults remain unchanged, with the exception of the new LZMS-compressed
544 WIMs, which use a larger chunk size by default.
546 The compression/decompression API exported by wimlib has been changed.
547 Now one set of functions handles all supported compression formats.
549 `wimcapture' and `wimappend' will now display the progress of scanning
550 the directory tree to capture, in addition to the progress of writing
551 data to the WIM. The '--verbose' option no longer does anything. The
552 library API change for this is the addition of several members to
553 `struct wimlib_progress_info_scan' available to progress callbacks.
555 `mkwinpeimg' now correctly handles the '--start-script' option when the
556 start script is not in the working directory.
558 Sequential extraction, previously requested by using
559 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
560 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
561 behavior (extract in file order).
564 The new LZX compressor added in v1.5.2 has been improved and is now
565 enabled by default, except when `wimcapture' or `wimappend' is run
566 *without* the '--compress' option, in which case the faster LZX
567 compressor is used (the same as before). This behavior is reasonably
568 consistent with ImageX which actually uses "fast" (XPRESS) compression
569 by default. In those cases, use '--compress=maximum' to explicitly
570 capture a WIM image using the new (slower but better) LZX compressor.
572 The '--compress-slow' option still exists to `wimlib-imagex optimize',
573 but its new behavior is to tweak the new LZX compressor even more to
574 produce an even better compression ratio at the cost of more time spent
577 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
578 which recompresses the WIM file using the specified compression TYPE.
579 The new library API function used for this is
580 wimlib_set_output_compression_type().
582 Added the wimlib_get_xml_data() function to allow library clients to
583 easily retrieve the raw XML data from a WIM file if needed.
585 Fixed a bug that could cause an error code to be incorrectly returned
586 when writing XML data containing a <WINDOWS> element.
588 Mounted WIM images will now correctly show the default file stream even
589 if appears in the alternate data stream entries of the corresponding WIM
593 Added a new experimental LZX compressor which can be enabled by passing
594 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
595 optimize'. (The latter is only applicable if the WIM is already
596 LZX-compressed and the '--recompress' option is also given.) The
597 experimental compressor is much slower but compresses the data slightly
598 more --- currently usually to within a fraction of a percent of the
599 results from WIMGAPI/ImageX.
601 A workaround has been added for compatibility with versions of WinPE
602 that interpret alternate data stream entries in the boot WIM
605 An alignment bug that caused a crash in the LZX decompressor on some
608 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
609 the WIM header when restoring the previous state of a WIM it failed to
612 Added a workaround to avoid an access denied error on Windows when
613 replacing a WIM file that another process has opened.
616 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
617 needed to be handled.
619 A bug in the interpretation of negative IMAGE indices in the
620 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
621 `wimlib-imagex append' has been fixed.
623 A workaround has been added to successfully apply security descriptors
624 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
625 2013.1.13 or earlier.
627 `wimlib-imagex capture' can now accept the '--delta-from' option
631 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
632 to standard output and applying images from standard input, but they are
633 not compatible with Microsoft's software and are not created by default.
634 See the documentation for --pipable flag of `wimlib-imagex capture' for
637 To better support incremental backups, added support for declaring an
638 image as a modified form of another image. See the documentation for
639 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
642 Added supported for "delta" WIMs. See the documentation for the
643 '--delta-from' option of `wimlib-imagex capture'.
645 The library support for managing split WIMs has been changed to support
646 other arrangements, such as delta WIMs, and be easier to use. This
647 change is visible in `wimlib-imagex', which also can now accept the
648 '--ref' option multiple times, and also now supports "delta" WIMs as
651 wimlib now preserves WIM integrity tables by default, even if
652 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
653 behavior of `wimlib-imagex' whenever the WIM being operated on contains
654 an integrity table and the '--check' option is not specified.
656 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
657 (when --compress is not specified). This provides the best compression
658 ratio by default, which is usually what is desired, at a cost of some
661 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
662 is the command as in `wimlib-imagex COMMAND'; for example, it can be
663 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
664 appropriate hard links are created in UNIX installations of
665 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
666 batch files that emulate this behavior are generated.
668 Security descriptors are now extracted correctly on Windows.
670 Fixed archiving DOS names in NTFS-3g capture mode.
672 The extraction code has been rewritten and it will now be easier to
673 support new features on all supported backends (currently Win32, UNIX,
674 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
675 now supported on all backends, not just UNIX.
677 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
678 than the WAIK itself.
680 wimlib_global_init() now, by default, attempts to acquire additional
681 privileges on Windows, so library clients need not do this.
683 This update bumps the shared library version number up to 9, since it is
684 not binary compatibible with previous releases.
687 Fixed bug in `wimlib-imagex export' that made it impossible to export an
688 image from a WIM that is readonly at the filesystem level.
690 Return error code rather than segfaulting when trying to list files from
691 a non-first part of a split WIM.
693 Joining a WIM will now preserve the RP_FIX and READONLY flags.
696 On Windows, paths given to wimlib-imagex are now treated case
699 Improved behavior regarding invalid filenames; in particular, on
700 Windows, wimlib-imagex will, when extracting, now omit (with an option
701 to override this default) filenames differing only in case, or filenames
702 containing characters not valid on Windows.
704 On Windows, wimlib now supports capturing and extracting long paths
705 (longer than the so-called MAX_PATH).
707 On Windows, `wimlib-imagex update' now acquires proper privileges when
708 running as an Administrator.
710 `wimlib-imagex update' will now complain if no image is specified when
711 trying to update a multi-image WIM.
713 `wimlib-imagex update' now supports specifying a single update command
714 directly on the command line using the --command option.
716 wimlib-imagex will now choose different units for progress messages,
717 depending on the amount of data that needs to be processed.
719 `wimlib-imagex append' will now generate a unique WIM image name if no
720 name is specified and the defaulted name already exists in the WIM.
722 wimlib now allows you to create unnamed WIM images, which can then only
723 be referred to by index.
725 wimlib now allows you to explicitly declare you want write access to a
726 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
729 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
732 Progress callbacks have been added to wimlib's wimlib_update_image()
735 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
736 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
739 NTFS-3g capture now only warns about two conditions previously treated
742 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
745 wimlib now correctly detects and returns an error when reading a WIM
746 image with a cyclic directory structure. (Fun fact: such a WIM will
747 crash Microsoft's software.)
750 Added new "extract" and "update" subcommands to wimlib-imagex, along
751 with associated APIs in the library. These commands are intended mainly
752 for Windows use but can be used on UNIX as well.
754 Many documentation improvements.
756 Fixed a bug in the Windows build where relative symbolic links were not
757 captured in reparse-point fixup mode.
759 Fixed a bug in the Windows build where file handles were left open to
760 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
762 Fixed a bug in the Windows build of wimlib-imagex where globbing
763 split-WIM parts could cause the program to crash.
765 Fixed a bug where the creation time of WIM images would be shown instead
766 of the last modification time.
768 With the Windows build it is now possible to restore a WIM containing
769 symbolic links as a non-Administrator; however you will receive warnings
770 about not being able to extract the symbolic links.
773 Capturing a WIM image should now be significantly faster in most cases
774 due to improved use of the operating system's cache and avoiding reading
775 files twice whenever possible.
777 The Windows build should now work on Windows XP.
779 The Windows build now supports capturing and restoring hidden,
780 compressed, sparse, and encrypted files.
782 The Windows build now supports capturing and applying WIM images from
783 filesystems other than NTFS (with some reduced functionality).
785 The Windows build now extracts short names correctly.
787 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
788 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
789 capture' and `wimlib-imagex apply'.
791 The performance of splitting and joining WIMs should be slightly
794 The LZX and XPRESS compression and decompression functions are now
795 exported from the library.
798 Improvements and bugfixes for the Windows build.
800 Added --strict-acls options.
802 Fixed the way that wimlib determines the order of images in the WIM.
805 Since wimlib can now be used on Windows, wimlib's implementation of
806 ImageX has been renamed to wimlib-imagex to avoid confusion with
807 Microsoft's implementation of ImageX, which would have the same file
808 name ("imagex.exe"). If you really don't like this you can pass the
809 --with-imagex-progname option to `configure' to choose a different name,
810 or even simply rename the binary yourself (but the former way will
811 configure the man pages to use the chosen name).
813 Various bugs fixed in the Windows build. Mainly to do with capturing
814 and restoring alternate data streams correctly in weird cases, and
815 requesting the correct privileges when opening files. Also added the
816 --noacls options to wimlib-imagex capture, append, and apply.
818 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
819 dynamically loaded, so this may make the library compatible with Windows
820 XP (however, there may still be other problems).
823 Added experimental support for native Windows builds. Binaries can be
824 downloaded from the SourceForge page.
826 --source-list option added to `imagex capture' and `imagex append'.
828 Better support for different character encodings.
831 Storing UNIX file owners, groups, and modes in WIM images is now
832 possible using `imagex capture' with the --unix-data flag.
834 Minor bug fixes and documentation fixes.
837 NTFS capture: Fixed capturing duplicate reparse points.
839 NTFS capture: Capture first unnamed stream if there are more than one
840 (print warning instead of error).
842 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
845 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
848 Update to work with ntfs-3g version 2013.1.13.
851 Fixed truncating file to shorter but non-zero length on read-write
854 Various code cleanups and minor documentation fixes.
857 LZX and XPRESS decompression have received some additional optimizations
858 and should now be even faster. (Although, they were already pretty
859 fast--- much faster than typical I/O speeds.)
861 Fixed a bug introduced in v1.2.1 that would cause a directory tree
862 containing hard links to be captured incorrectly in some cases.
865 By default, unmounting a read-write mounted WIM with 'imagex unmount
866 --commit' will now change the WIM in-place without needing to write the
867 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
870 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
871 for a response from the daemon servicing the mounted WIM. Instead,
872 every second 'imagex unmount' will check if the daemon is still alive,
873 and keep waiting if so, otherwise terminate with an error.
875 'imagex unmount --commit' on a read-write mounted WIM will now print
876 progress information regarding the writing of new or modified streams
877 the WIM, just like when capturing or appending a WIM.
879 A small change has been made to XPRESS compression and it should improve
880 the compression ratio slightly.
882 A change was made that may improve performance slightly when applying a
883 WIM image to a NTFS volume.
885 Microsoft has managed to introduce even more bugs into their software,
886 and now the WIMs for Windows 8 have incorrect (too low) reference counts
887 for some streams. This is unsafe because such streams can be removed
888 when they are in actuality still referenced in the WIM (perhaps by a
889 different image). wimlib will now work around this problem by fixing
890 the stream reference counts. This is only done when wimlib_delete_image() is
891 called ('imagex delete') or when wimlib_mount_image() is called with
892 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
893 requires reading the metadata for all images in the WIM, so this will
894 make these operations noticably slower on WIMs with multiple images.
896 Various other bugfixes.
899 Appending images to a WIM is now be done by default without re-building
900 the whole WIM. Use the --rebuild flag to get the old behavior (which
901 was to re-build the entire WIM when a new image is appended).
903 A new command `imagex optimize' is now available to manually re-build a
904 WIM that has wasted space due to repeated appends.
906 Progress information has been improved, and now arbitrary callback
907 functions can be used to show the progress of a WIM operation.
909 A possible bug with changing the bootable image of a WIM was fixed.
911 Some advisory locking is now done to prevent two processes from
912 modifying a WIM at the same time (but only in some cases). For example,
913 you cannot mount two images from a WIM read-write at the same time.
915 Some functions have been reorganized:
916 * wimlib_mount() renamed to wimlib_mount_image().
917 * wimlib_unmount() renamed to wimlib_unmount_image().
918 * wimlib_overwrite_xml_and_header() removed as
919 wimlib_overwrite() suffices now.
920 * wimlib_apply_image_to_ntfs_volume() removed as
921 wimlib_extract_image() suffices now.
922 * wimlib_add_image_from_ntfs_volume() removed as
923 * wimlib_add_image() suffices now.
925 Previously, the soname of libwim.so has been 0.0.0, despite many
926 interface changes. The soname is now updated to 1.0.0 and will now be
927 updated each release.
930 Resources will now be compressed using multiple threads by default.
931 (This applies to `imagex capture', `imagex append', and `imagex
934 Some performance improvements in mounted WIMs.
936 More progress information is shown when capturing a WIM.
939 Lots of minor fixes, code cleanups, and some documentation updates.
940 Nothing in particular is really noteworthy.
943 LZX and XPRESS compression improvements.
945 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
946 Link Bytes of the WIM.
949 Fixed bug when capturing NTFS file with multiple named data streams.
951 Internally, we are now using inode structures, even though these don't
952 appear literally in the WIM file. This simplifies some of the code
953 (mainly for WIM mounting) and likely fixed a few problems, although it
957 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
961 Enough changes to call it version 1.0.0!
963 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
964 to a NTFS volume, is now supported.
966 Hard links and symbolic links have much improved support. They are
967 supported for WIM capture, WIM application, and mounted WIMs (you can
968 even make them on read-write mounted WIMs).
970 Alternate data streams are now supported on mounted WIMs through an
971 xattr or a Windows-style stream interface. Also they are supported when
972 capturing a WIM from NTFS or applying a WIM to NTFS.
974 Split WIMs are better supported. You may now apply an image directly
975 from a split WIM, mount an image from a split WIM read-only, or export
976 an image from a split WIM.
978 Using a capture configuration file is now supported (but not fully yet).
980 SHA1 message digests are checked in more places, so we can make sure
981 applied and captured data is correct.
983 Man pages have been updated and consolidated.
986 Fixed segfault when unmounting read-only WIM.
989 Support for joining and splitting WIMs.
990 Also, security data is now preserved by default.
993 Can now build with older gcc and system headers, like on CentOS 5.
996 Fixed bug that made it impossible to overwrite files in read-write
1000 Write byte-order mark before WIM XML data. (imagex.exe requires this to
