2 'wimcapture' now requires confirmation before overwriting an existing
3 archive. Scripts that relied on the old behavior will need to add the
4 '--force' option, or delete the existing archive first.
6 'wimappend' will now create the WIM archive if it doesn't yet exist
7 (thereby acting like 'wimcapture' in that scenario).
9 The LZX compression ratio has been slightly improved. The default mode,
10 LZX level 50, is now almost as good as the old LZX level 100, while
11 being nearly the same speed as before.
13 Decompression performance has been slightly improved.
15 Filenames are now always listed in NTFS collation order.
17 On UNIX-like systems, wimlib can now process Windows filenames that are
18 not valid Unicode due to the presence of unpaired surrogates.
20 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
21 addition of surrogate codepoints. Consequently, the environmental
22 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
23 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
25 wimlib no longer depends on iconv.
27 Reduced memory usage slightly.
29 When a WIM image is applied in NTFS-3G mode, security descriptors are
30 now created in NTFS v3.0 format when supported by the volume.
32 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
33 been removed. Users are advised to upgrade to a later version of
36 On Windows, wimlib now supports case-sensitive filename extraction when
37 supported by the underlying operating system and filesystem (operating
38 system support requires a registry setting).
41 On UNIX, wimlib can now overwrite readonly files when extracting.
43 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
44 NTFS permissions") set on some existing directories after extraction.
46 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
47 driver is not loaded, wimlib can now correctly register a new WIM file
48 with the target volume when the target volume previously had had WIM
51 Added a new testing program.
53 Clarified the main license text and updated public domain dedications
54 for certain files to be more thorough.
57 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
59 Reduced memory usage when exporting large numbers of WIM images.
61 Non UTF-8 locales are now detected correctly.
63 Addressed compiler warnings and enabled "silent" make rules by default.
65 Windows-specific updates:
66 Fixed a bug where duplicate backslashes could be generated in
67 link targets when extracting symbolic links and junctions.
69 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
70 work if their full path contained a space.
72 Fixed bugs related to scanning SMB filesystems.
74 Added warning message about known issue with WindowsApps folder.
76 Added instructions for building from source on Windows.
78 VSS support is no longer marked "experimental".
80 Added missing license file for libdivsufsort-lite.
83 Added experimental support for Windows VSS (Volume Shadow Copy Service).
84 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
85 create and use a temporary VSS snapshot when capturing a WIM image.
87 Implemented setting of Windows-specific XML information, such as
88 architecture, system root, and version details. This information is now
89 automatically set in newly captured WIM images, when appropriate.
91 Improved performance of directory tree scans on Windows.
93 On Windows, to improve capture performance, wimlib now sometimes opens
94 files by inode number rather than by path. This is enabled for
95 wimcapture and wimappend, but for now other applications have to opt-in.
97 The progress messages printed by wimlib-imagex while writing WIM files
98 have been slightly tweaked.
100 Progress information for directory tree scans now counts all hard links.
101 Also, on Windows "\\?\" is no longer stripped from the current path.
103 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
104 'wiminfo'. This option lets you assign values to elements in a WIM
105 file's XML document by name.
107 The wimlib_get_image_property() and wimlib_set_image_property() API
108 functions now support numerically indexed elements.
110 Fixed a bug where, on Windows, wimlib would change the security
111 descriptor of the target directory of an extraction even when the
112 '--no-acls' option was specified.
115 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
116 some Microsoft software would not correctly recognize data in the
117 resulting filesystem.
119 Made some small improvements to the compression algorithms:
120 LZX compression ratio was slightly improved.
121 XPRESS compression ratio and speed was slightly improved.
122 LZMS compression speed was slightly improved.
124 Improved handling of WIM XML data. wimlib no longer drops unrecognized
125 elements when exporting images. In addition, two API functions were
126 added for better access to elements in the XML document:
127 wimlib_get_image_property() and wimlib_set_image_property().
129 Added support for (unsafe) in-place compaction of WIM files.
131 Improved performance of image export by reusing metadata resources
132 instead of always rebuilding and recompressing them.
134 Improved performance of wimlib_update_image() by delaying the update to
135 the WIM's XML document until a write is requested.
137 On Windows, the target of an extraction may now be a reparse point
138 (which will be dereferenced).
140 On Windows, wimlib now correctly restores non-Microsoft reparse points.
141 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
143 On Windows, wimlib now has improved performance when archiving files
144 from a filesystem backed by a WIM (a "WIMBoot" setup).
146 Several improvements to System Compression (compact mode) support:
148 wof.sys (or wofadk.sys) is now automatically attached to the
149 target volume if needed.
151 Compact-mode extractions now work correctly with wofadk.sys on
152 older versions of Windows.
154 For compatibility with the Windows bootloader, the requested
155 compression format now is overridden on certain files.
157 Other minor bugfixes.
160 This release primarily contains various minor bug fixes and
161 improvements, including:
163 Improved handling of deep directory structures.
165 Fixed a bug where on 32-bit systems, the library could enter an
166 infinite loop if a WIM file was malformed in a specific way.
168 Added a workaround for a case where libntfs-3g may report
169 duplicate streams in an NTFS file.
171 Windows symbolic links and junctions in mounted WIM images are
172 now automatically rewritten to be valid in the mounted location.
174 Reparse point fixes: correctly handle the "ReparseReserved"
175 field, and correctly handle "empty" (data-less) reparse points.
177 On Windows, wimlib now acquires SeManageVolumePrivilege, which
178 is needed to create externally backed files using the
181 Improved validation of filenames.
183 Improved LZMS decompression speed.
185 The configure script now honors alternate pkg-config settings.
187 Links have been updated to point to the new website.
189 In addition, experimental support has been added for compressing
190 extracted files using System Compression on Windows 10. This
191 functionality is available through the new '--compact' option to
192 'wimapply' and 'wimextract' as well as new library flags.
195 Fixed a bug in the LZX decompressor: malicious input data could cause
196 out of bounds writes to memory (since wimlib v1.2.2).
198 The output of the 'wiminfo' command now consolidates various boolean
199 flags (such as "Relative path junction") into a single line.
201 A file can now have both an unnamed data stream ("file contents") and a
202 reparse point stream. Such files can exist as a result of the use of
203 certain Windows features, such as offline storage, including "OneDrive".
204 wimlib will now store and restore both streams on Windows as well as in
205 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
207 On Windows, named data streams of encrypted files are no longer stored
208 twice in WIM archives.
210 On Windows, named data streams are now correctly extracted to existing
211 "readonly" directories. Before, an error would be reported.
213 On Windows, it is now possible to do a "WIMBoot mode" extraction with
214 non-standalone WIMs such as delta WIMs.
216 On Windows, when doing an extraction in "WIMBoot mode", files larger
217 than 4 gigabytes are now never extracted as externally backed. This
218 works around a bug in Microsoft's "WOF" driver.
220 The '--enable-verify-compression' configure option has been removed. If
221 you want to verify a WIM file, use the 'wimverify' program.
223 The way the "file count", "directory count", "total bytes", and "hard
224 link bytes" image statistics (stored in the WIM XML data) is calculated
225 has been slightly changed.
227 In mounted WIM images, the disk usage provided for each file (st_blocks)
228 is now the compressed size rather than the uncompressed size.
230 The performance of the NTFS-3g and Windows capture modes has been
233 On UNIX-like systems, symbolic links whose targets contain the backslash
234 character are now handled correctly (losslessly).
237 Improved the LZX compressor. It is now 15-20% faster than before and
238 provides a slightly better compression ratio.
240 Improved the LZMS compressor. It now provides a compression ratio
241 slightly better than WIMGAPI while still being faster and using slightly
244 The compression chunk size in solid resources, e.g. when capturing or
245 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
246 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
247 better compression ratio and is the same value that WIMGAPI uses. The
248 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
249 lower than WIMGAPI's memory usage, but if it is too much, it is still
250 possible to choose a lower value, e.g. with the '--solid-chunk-size'
251 option to wimlib-imagex.
253 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
254 accept the 'K', 'M', and 'G' suffixes.
256 Files are now sorted by name extension when creating a solid WIM file.
258 Fixed various issues related to capture/apply of EFS-encrypted files on
261 The file list printed by 'wimdir' is now sorted by the platform-specific
262 case sensitivity setting, rather than always case sensitively. This
263 also affects the library function wimlib_iterate_dir_tree().
265 On Windows, some error and warning messages have been improved.
268 The Windows binary distribution no longer contains third party DLLs.
269 These dependencies are instead compiled directly into the libwim DLL.
271 Added more fixes for wimlib on non-x86 architectures such as ARM.
273 Extracting files to a Windows PE in-memory filesystem no longer fails if
274 the target files do not yet exist.
276 Improved the performance of XPRESS compression and LZMS decompression.
278 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
279 It will automatically be faster on newer Intel and AMD processors.
281 Removed the --with-imagex-progname and --enable-more-assertions
285 Fix for very slow export from solid WIM / ESD files.
287 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
289 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
290 may use this to treat some types of errors as non-fatal.
292 The library now permits making in-memory changes to a WIMStruct backed
293 by a read-only WIM file.
295 Fixes for "WIMBoot" extraction mode (Windows only):
297 When not using the WOF driver, extraction no longer fails if the
298 disk containing the WIM file has too many partitions.
300 When matching patterns in [PrepopulateList], all hard links of
301 each file are now considered.
303 The system registry files are now automatically treated as being
304 in [PrepopulateList].
306 Added a hack to try to work around an intermittent bug in
307 Microsoft's WOF (Windows Overlay Filesystem) driver.
310 Made more improvements to the XPRESS, LZX, and LZMS compressors.
312 A number of improvements to the Windows port:
314 Fixes for setting short filenames.
316 Faster "WIMBoot" extraction.
318 Updated and slimmed down the dependent DLLs.
320 ACL inheritence bits are now restored.
322 Mandatory integrity labels are now backed up and restored.
324 Added a workaround for an issue where in rare cases, wimlib could create
325 a compressed data stream that could not be read correctly by Windows
326 after an extraction in "WIMBoot" mode.
329 Added file count progress data for
330 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
331 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
333 Added support for testing file exclusions via the user-provided
336 Some documentation improvements.
338 Made some clarifications to the license text in the COPYING file.
341 Made more improvements to the XPRESS, LZX, and LZMS compressors.
343 The default compression mode for wimcapture is now LZX compression in
344 its default mode, which is the same as '--compress=maximum'.
346 You can now specify an optional integer compression level to the
347 '--compress' option; e.g. '--compress=lzx:75'.
349 Made a minor change to the LZMS compressor and decompressor to fix an
350 incompatibility with the Microsoft implementation. In the unlikely
351 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
352 earlier and a checksum error is reported when extracting files from it
353 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
356 Added 'verify' subcommand to wimlib-imagex.
358 Notable library changes:
360 Custom compressor parameters have been removed from the library
361 in favor of the simpler level-based API.
363 Decompressor parameters have been removed entirely.
365 Library users can now specify a custom file for warning and
366 error messages to be sent to, rather than the default of
369 New progress messages:
370 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
371 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
373 New function: wimlib_verify_wim().
376 Improved compression, decompression, and extraction performance.
378 Improved compatibility with version 3584 WIM / ESD files:
379 - Add support for reading and writing multiple solid blocks per
380 archive, which WIMGAPI/DISM can create when appending an image.
381 - Correctly create solid blocks larger than 4 GiB.
383 'add' commands passed to wimupdate will now replace existing
384 nondirectory files by default. Use the --no-replace option to get the
387 The license for the library now contains an exception that allows using
388 it under the LGPL. See the COPYING file for details.
390 In reparse-point fixup mode (the default for capture), symbolic links
391 and junctions that point outside the tree being captured are no longer
392 excluded from capture.
394 Added support for "WIMBoot" capture and extraction. See the
395 documentation for the new '--wimboot' option to wimcapture and wimapply
396 for more information.
398 On UNIX-like systems, you can now backup and restore device nodes, named
399 pipes, and sockets. In addition, 32-bit user and group IDs are now
402 The way that UNIX data is stored in WIM files has been changed. If you
403 captured any WIMs with the --unix-data option, to upgrade them you'll
404 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
405 re-capture them with --unix-data using this version.
407 wimlib now understands tagged metadata items, such as object IDs, that
408 can be stored in WIM directory entries.
410 Removed the --hardlink and --symlink options to wimapply, since I don't
411 think they are too useful and they got in the way of improving the code.
413 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
415 The 'mkwinpeimg' script now supports writing the ISO image to standard
418 The <ARCH> element in WIM XML data is now exported correctly.
420 On Windows, sparse file attributes are no longer set on extracted files.
421 Oddly enough, this actually saves disk space in some cases.
423 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
424 supported. Mounting WIM images now always requires extended attribute
425 support. Use --without-fuse to disable support for mounting WIM images;
426 this will also disable the need for extended attribute support.
428 Configuring with --enable-ssse3-sha1 now works correctly.
430 The shared library version has been bumped up. The main
431 incompatibilities are:
433 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
434 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
437 - User-provided progress functions are now registered using a
438 separate function, wimlib_register_progress_function(). The
439 'progress_func' argument to many functions no longer exists.
441 - The return value from user-provided progress functions is now
444 - A context argument has been added to the prototype of
445 user-provided progress functions.
447 - 'struct wimlib_capture_config' has been removed. The library
448 now takes the path to the configuration file directly. This
449 affects wimlib_add_image(), wimlib_add_image_multisource(),
450 and wimlib_update_image(). However, a NULL value passed in
451 the argument retains the same meaning.
453 - Removed deprecated functions: some (de)compression functions,
454 wimlib_extract_files(), and wimlib_print_metadata().
456 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
457 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
458 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
460 - Removed some progress messages:
461 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
462 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
463 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
466 - Removed some error codes. Numbering stays the same.
468 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
469 WIMLIB_UNMOUNT_FLAG_FORCE.
471 - WIM paths passed to progress functions now have a leading
475 Case-insensitive comparisons of strings (e.g. filenames) containing
476 UTF-16 codepoints above 32767 are now done correctly.
478 Fixed build failure on Mac OS X.
480 wimunmount now provides the '--new-image' option to cause changes to a
481 read-write mounted image to be committed as a new image rather than as
482 an update of the mounted image. (The corresponding new library flag is
483 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
485 The LZMS ("recovery") compression chunk size, or "dictionary size", may
486 now be up to 1 GiB (1,073,741,824 bytes).
488 The performance of LZX ("maximum") and LZMS ("recovery") compression
489 with large chunk sizes has been slightly improved.
492 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
493 decompressed correctly.
495 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
496 occurred in an unlikely case, and due to validity checks it did not
497 affect successfully created archives.
499 Fixed a minor compatibility issue with the LZMS compressor and
500 decompressor. This is *not* the default compression type and was only
501 introduced in v1.6.0. In the unlikely event that you created an
502 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
503 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
506 Memory usage for LZMS and LZX compression has been decreased.
508 wimextract now allows wildcard characters in paths specified on the
509 command line. Also, the '--strict-wildcards' option has been removed
510 and replaced with the inverse option '--nullglob'. See the
511 documentation for wimextract for more details and changes.
513 The wimlib_extract_files() function is now considered deprecated in
514 favor of wimlib_extract_paths().
516 Fixed more permissions problems when extracting files on Windows.
518 A new '--no-attributes' option has been added to wimapply and
519 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
521 The default chunk size is now set correctly when changing the
522 compression type of a WIM, for example with 'wimoptimize'.
524 The '--metadata' option to wiminfo has been replaced with the
525 '--detailed' option to wimdir.
527 In relevant wimlib-imagex commands, '--solid' may now be used as an
528 alias for '--pack-streams'.
531 Support for extracting and updating the new version 3584 WIMs has been
532 added. These WIMs typically pack many streams ("files") together into a
533 single compressed resource, thereby saving space. This degrades the
534 performance of random access (such as that which occurs on a mounted
535 image), but optimizations have been implemented for extraction. These
536 new WIM files also typically use a new compression format (LZMS), which
537 is similar to LZMA and can offer a better compression ratio than LZX.
538 These new WIM files can be created using `wimcapture' with
539 the '--compress=lzms --pack-streams' options. Note: this new WIM format
540 is used by the Windows 8 web downloader, but important segments of the
541 raw '.esd' files are encrypted, so wimlib will not be able to extract
542 such files until they are first decrypted.
544 wimlib now supports extracting files and directories from a WIM image
545 based on a "listfile" that itself contains the list of paths to extract.
546 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
547 and for the library itself, the new APIs are wimlib_extract_pathlist()
548 and wimlib_extract_paths(). Path globs containing wildcard characters
551 For searching WIM files, wimlib now has configurable case sensitivity.
552 The default on Windows is still case-insensitive and the default on
553 UNIX-like systems is still case-sensitive, but this can be overridden
554 on either platform through flags to wimlib_global_init(). For
555 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
556 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
559 Support for compression chunk sizes greater than the default of 32768
560 bytes has been added. A larger chunk size typically results in a better
561 compression ratio. However, the MS implementation is seemingly not
562 compatible with all chunk sizes, especially for LZX compression, so the
563 defaults remain unchanged, with the exception of the new LZMS-compressed
564 WIMs, which use a larger chunk size by default.
566 The compression/decompression API exported by wimlib has been changed.
567 Now one set of functions handles all supported compression formats.
569 `wimcapture' and `wimappend' will now display the progress of scanning
570 the directory tree to capture, in addition to the progress of writing
571 data to the WIM. The '--verbose' option no longer does anything. The
572 library API change for this is the addition of several members to
573 `struct wimlib_progress_info_scan' available to progress callbacks.
575 `mkwinpeimg' now correctly handles the '--start-script' option when the
576 start script is not in the working directory.
578 Sequential extraction, previously requested by using
579 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
580 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
581 behavior (extract in file order).
584 The new LZX compressor added in v1.5.2 has been improved and is now
585 enabled by default, except when `wimcapture' or `wimappend' is run
586 *without* the '--compress' option, in which case the faster LZX
587 compressor is used (the same as before). This behavior is reasonably
588 consistent with ImageX which actually uses "fast" (XPRESS) compression
589 by default. In those cases, use '--compress=maximum' to explicitly
590 capture a WIM image using the new (slower but better) LZX compressor.
592 The '--compress-slow' option still exists to `wimlib-imagex optimize',
593 but its new behavior is to tweak the new LZX compressor even more to
594 produce an even better compression ratio at the cost of more time spent
597 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
598 which recompresses the WIM file using the specified compression TYPE.
599 The new library API function used for this is
600 wimlib_set_output_compression_type().
602 Added the wimlib_get_xml_data() function to allow library clients to
603 easily retrieve the raw XML data from a WIM file if needed.
605 Fixed a bug that could cause an error code to be incorrectly returned
606 when writing XML data containing a <WINDOWS> element.
608 Mounted WIM images will now correctly show the default file stream even
609 if appears in the alternate data stream entries of the corresponding WIM
613 Added a new experimental LZX compressor which can be enabled by passing
614 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
615 optimize'. (The latter is only applicable if the WIM is already
616 LZX-compressed and the '--recompress' option is also given.) The
617 experimental compressor is much slower but compresses the data slightly
618 more --- currently usually to within a fraction of a percent of the
619 results from WIMGAPI/ImageX.
621 A workaround has been added for compatibility with versions of WinPE
622 that interpret alternate data stream entries in the boot WIM
625 An alignment bug that caused a crash in the LZX decompressor on some
628 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
629 the WIM header when restoring the previous state of a WIM it failed to
632 Added a workaround to avoid an access denied error on Windows when
633 replacing a WIM file that another process has opened.
636 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
637 needed to be handled.
639 A bug in the interpretation of negative IMAGE indices in the
640 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
641 `wimlib-imagex append' has been fixed.
643 A workaround has been added to successfully apply security descriptors
644 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
645 2013.1.13 or earlier.
647 `wimlib-imagex capture' can now accept the '--delta-from' option
651 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
652 to standard output and applying images from standard input, but they are
653 not compatible with Microsoft's software and are not created by default.
654 See the documentation for --pipable flag of `wimlib-imagex capture' for
657 To better support incremental backups, added support for declaring an
658 image as a modified form of another image. See the documentation for
659 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
662 Added supported for "delta" WIMs. See the documentation for the
663 '--delta-from' option of `wimlib-imagex capture'.
665 The library support for managing split WIMs has been changed to support
666 other arrangements, such as delta WIMs, and be easier to use. This
667 change is visible in `wimlib-imagex', which also can now accept the
668 '--ref' option multiple times, and also now supports "delta" WIMs as
671 wimlib now preserves WIM integrity tables by default, even if
672 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
673 behavior of `wimlib-imagex' whenever the WIM being operated on contains
674 an integrity table and the '--check' option is not specified.
676 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
677 (when --compress is not specified). This provides the best compression
678 ratio by default, which is usually what is desired, at a cost of some
681 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
682 is the command as in `wimlib-imagex COMMAND'; for example, it can be
683 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
684 appropriate hard links are created in UNIX installations of
685 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
686 batch files that emulate this behavior are generated.
688 Security descriptors are now extracted correctly on Windows.
690 Fixed archiving DOS names in NTFS-3g capture mode.
692 The extraction code has been rewritten and it will now be easier to
693 support new features on all supported backends (currently Win32, UNIX,
694 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
695 now supported on all backends, not just UNIX.
697 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
698 than the WAIK itself.
700 wimlib_global_init() now, by default, attempts to acquire additional
701 privileges on Windows, so library clients need not do this.
703 This update bumps the shared library version number up to 9, since it is
704 not binary compatibible with previous releases.
707 Fixed bug in `wimlib-imagex export' that made it impossible to export an
708 image from a WIM that is readonly at the filesystem level.
710 Return error code rather than segfaulting when trying to list files from
711 a non-first part of a split WIM.
713 Joining a WIM will now preserve the RP_FIX and READONLY flags.
716 On Windows, paths given to wimlib-imagex are now treated case
719 Improved behavior regarding invalid filenames; in particular, on
720 Windows, wimlib-imagex will, when extracting, now omit (with an option
721 to override this default) filenames differing only in case, or filenames
722 containing characters not valid on Windows.
724 On Windows, wimlib now supports capturing and extracting long paths
725 (longer than the so-called MAX_PATH).
727 On Windows, `wimlib-imagex update' now acquires proper privileges when
728 running as an Administrator.
730 `wimlib-imagex update' will now complain if no image is specified when
731 trying to update a multi-image WIM.
733 `wimlib-imagex update' now supports specifying a single update command
734 directly on the command line using the --command option.
736 wimlib-imagex will now choose different units for progress messages,
737 depending on the amount of data that needs to be processed.
739 `wimlib-imagex append' will now generate a unique WIM image name if no
740 name is specified and the defaulted name already exists in the WIM.
742 wimlib now allows you to create unnamed WIM images, which can then only
743 be referred to by index.
745 wimlib now allows you to explicitly declare you want write access to a
746 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
749 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
752 Progress callbacks have been added to wimlib's wimlib_update_image()
755 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
756 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
759 NTFS-3g capture now only warns about two conditions previously treated
762 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
765 wimlib now correctly detects and returns an error when reading a WIM
766 image with a cyclic directory structure. (Fun fact: such a WIM will
767 crash Microsoft's software.)
770 Added new "extract" and "update" subcommands to wimlib-imagex, along
771 with associated APIs in the library. These commands are intended mainly
772 for Windows use but can be used on UNIX as well.
774 Many documentation improvements.
776 Fixed a bug in the Windows build where relative symbolic links were not
777 captured in reparse-point fixup mode.
779 Fixed a bug in the Windows build where file handles were left open to
780 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
782 Fixed a bug in the Windows build of wimlib-imagex where globbing
783 split-WIM parts could cause the program to crash.
785 Fixed a bug where the creation time of WIM images would be shown instead
786 of the last modification time.
788 With the Windows build it is now possible to restore a WIM containing
789 symbolic links as a non-Administrator; however you will receive warnings
790 about not being able to extract the symbolic links.
793 Capturing a WIM image should now be significantly faster in most cases
794 due to improved use of the operating system's cache and avoiding reading
795 files twice whenever possible.
797 The Windows build should now work on Windows XP.
799 The Windows build now supports capturing and restoring hidden,
800 compressed, sparse, and encrypted files.
802 The Windows build now supports capturing and applying WIM images from
803 filesystems other than NTFS (with some reduced functionality).
805 The Windows build now extracts short names correctly.
807 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
808 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
809 capture' and `wimlib-imagex apply'.
811 The performance of splitting and joining WIMs should be slightly
814 The LZX and XPRESS compression and decompression functions are now
815 exported from the library.
818 Improvements and bugfixes for the Windows build.
820 Added --strict-acls options.
822 Fixed the way that wimlib determines the order of images in the WIM.
825 Since wimlib can now be used on Windows, wimlib's implementation of
826 ImageX has been renamed to wimlib-imagex to avoid confusion with
827 Microsoft's implementation of ImageX, which would have the same file
828 name ("imagex.exe"). If you really don't like this you can pass the
829 --with-imagex-progname option to `configure' to choose a different name,
830 or even simply rename the binary yourself (but the former way will
831 configure the man pages to use the chosen name).
833 Various bugs fixed in the Windows build. Mainly to do with capturing
834 and restoring alternate data streams correctly in weird cases, and
835 requesting the correct privileges when opening files. Also added the
836 --noacls options to wimlib-imagex capture, append, and apply.
838 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
839 dynamically loaded, so this may make the library compatible with Windows
840 XP (however, there may still be other problems).
843 Added experimental support for native Windows builds. Binaries can be
844 downloaded from the SourceForge page.
846 --source-list option added to `imagex capture' and `imagex append'.
848 Better support for different character encodings.
851 Storing UNIX file owners, groups, and modes in WIM images is now
852 possible using `imagex capture' with the --unix-data flag.
854 Minor bug fixes and documentation fixes.
857 NTFS capture: Fixed capturing duplicate reparse points.
859 NTFS capture: Capture first unnamed stream if there are more than one
860 (print warning instead of error).
862 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
865 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
868 Update to work with ntfs-3g version 2013.1.13.
871 Fixed truncating file to shorter but non-zero length on read-write
874 Various code cleanups and minor documentation fixes.
877 LZX and XPRESS decompression have received some additional optimizations
878 and should now be even faster. (Although, they were already pretty
879 fast--- much faster than typical I/O speeds.)
881 Fixed a bug introduced in v1.2.1 that would cause a directory tree
882 containing hard links to be captured incorrectly in some cases.
885 By default, unmounting a read-write mounted WIM with 'imagex unmount
886 --commit' will now change the WIM in-place without needing to write the
887 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
890 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
891 for a response from the daemon servicing the mounted WIM. Instead,
892 every second 'imagex unmount' will check if the daemon is still alive,
893 and keep waiting if so, otherwise terminate with an error.
895 'imagex unmount --commit' on a read-write mounted WIM will now print
896 progress information regarding the writing of new or modified streams
897 the WIM, just like when capturing or appending a WIM.
899 A small change has been made to XPRESS compression and it should improve
900 the compression ratio slightly.
902 A change was made that may improve performance slightly when applying a
903 WIM image to a NTFS volume.
905 Microsoft has managed to introduce even more bugs into their software,
906 and now the WIMs for Windows 8 have incorrect (too low) reference counts
907 for some streams. This is unsafe because such streams can be removed
908 when they are in actuality still referenced in the WIM (perhaps by a
909 different image). wimlib will now work around this problem by fixing
910 the stream reference counts. This is only done when wimlib_delete_image() is
911 called ('imagex delete') or when wimlib_mount_image() is called with
912 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
913 requires reading the metadata for all images in the WIM, so this will
914 make these operations noticably slower on WIMs with multiple images.
916 Various other bugfixes.
919 Appending images to a WIM is now be done by default without re-building
920 the whole WIM. Use the --rebuild flag to get the old behavior (which
921 was to re-build the entire WIM when a new image is appended).
923 A new command `imagex optimize' is now available to manually re-build a
924 WIM that has wasted space due to repeated appends.
926 Progress information has been improved, and now arbitrary callback
927 functions can be used to show the progress of a WIM operation.
929 A possible bug with changing the bootable image of a WIM was fixed.
931 Some advisory locking is now done to prevent two processes from
932 modifying a WIM at the same time (but only in some cases). For example,
933 you cannot mount two images from a WIM read-write at the same time.
935 Some functions have been reorganized:
936 * wimlib_mount() renamed to wimlib_mount_image().
937 * wimlib_unmount() renamed to wimlib_unmount_image().
938 * wimlib_overwrite_xml_and_header() removed as
939 wimlib_overwrite() suffices now.
940 * wimlib_apply_image_to_ntfs_volume() removed as
941 wimlib_extract_image() suffices now.
942 * wimlib_add_image_from_ntfs_volume() removed as
943 * wimlib_add_image() suffices now.
945 Previously, the soname of libwim.so has been 0.0.0, despite many
946 interface changes. The soname is now updated to 1.0.0 and will now be
947 updated each release.
950 Resources will now be compressed using multiple threads by default.
951 (This applies to `imagex capture', `imagex append', and `imagex
954 Some performance improvements in mounted WIMs.
956 More progress information is shown when capturing a WIM.
959 Lots of minor fixes, code cleanups, and some documentation updates.
960 Nothing in particular is really noteworthy.
963 LZX and XPRESS compression improvements.
965 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
966 Link Bytes of the WIM.
969 Fixed bug when capturing NTFS file with multiple named data streams.
971 Internally, we are now using inode structures, even though these don't
972 appear literally in the WIM file. This simplifies some of the code
973 (mainly for WIM mounting) and likely fixed a few problems, although it
977 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
981 Enough changes to call it version 1.0.0!
983 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
984 to a NTFS volume, is now supported.
986 Hard links and symbolic links have much improved support. They are
987 supported for WIM capture, WIM application, and mounted WIMs (you can
988 even make them on read-write mounted WIMs).
990 Alternate data streams are now supported on mounted WIMs through an
991 xattr or a Windows-style stream interface. Also they are supported when
992 capturing a WIM from NTFS or applying a WIM to NTFS.
994 Split WIMs are better supported. You may now apply an image directly
995 from a split WIM, mount an image from a split WIM read-only, or export
996 an image from a split WIM.
998 Using a capture configuration file is now supported (but not fully yet).
1000 SHA1 message digests are checked in more places, so we can make sure
1001 applied and captured data is correct.
1003 Man pages have been updated and consolidated.
1006 Fixed segfault when unmounting read-only WIM.
1009 Support for joining and splitting WIMs.
1010 Also, security data is now preserved by default.
1013 Can now build with older gcc and system headers, like on CentOS 5.
1016 Fixed bug that made it impossible to overwrite files in read-write
1020 Write byte-order mark before WIM XML data. (imagex.exe requires this to
