2 Updated 'mkwinpeimg' to work correctly on images that have a "windows"
3 (lower case) directory rather than a "Windows" (upper case) directory.
5 Fixed configuring with --enable-ssse3-sha1 from release tarball
6 (the file nasm_lt.sh was missing).
8 The development files needed to link with wimlib using Visual Studio are
9 now included in the Windows release archives.
11 wimlib.h can now be included by Visual Studio without errors.
13 The example programs can now be compiled in C++ mode, and they also now
17 The LZX compression ratio has been slightly improved. The default mode,
18 LZX level 50, is now almost as good as the old LZX level 100, while
19 being nearly the same speed as before.
21 Decompression performance has been slightly improved.
23 Filenames are now always listed in NTFS collation order.
25 On UNIX-like systems, wimlib can now process Windows filenames that are
26 not valid Unicode due to the presence of unpaired surrogates.
28 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
29 addition of surrogate codepoints. Consequently, the environmental
30 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
31 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
33 wimlib no longer depends on iconv.
35 Reduced memory usage slightly.
37 When a WIM image is applied in NTFS-3G mode, security descriptors are
38 now created in NTFS v3.0 format when supported by the volume.
40 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
41 been removed. Users are advised to upgrade to a later version of
44 On Windows, wimlib now supports case-sensitive filename extraction when
45 supported by the underlying operating system and filesystem (operating
46 system support requires a registry setting).
49 On UNIX, wimlib can now overwrite readonly files when extracting.
51 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
52 NTFS permissions") set on some existing directories after extraction.
54 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
55 driver is not loaded, wimlib can now correctly register a new WIM file
56 with the target volume when the target volume previously had had WIM
59 Added a new testing program.
61 Clarified the main license text and updated public domain dedications
62 for certain files to be more thorough.
65 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
67 Reduced memory usage when exporting large numbers of WIM images.
69 Non UTF-8 locales are now detected correctly.
71 Addressed compiler warnings and enabled "silent" make rules by default.
73 Windows-specific updates:
74 Fixed a bug where duplicate backslashes could be generated in
75 link targets when extracting symbolic links and junctions.
77 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
78 work if their full path contained a space.
80 Fixed bugs related to scanning SMB filesystems.
82 Added warning message about known issue with WindowsApps folder.
84 Added instructions for building from source on Windows.
86 VSS support is no longer marked "experimental".
88 Added missing license file for libdivsufsort-lite.
91 Added experimental support for Windows VSS (Volume Shadow Copy Service).
92 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
93 create and use a temporary VSS snapshot when capturing a WIM image.
95 Implemented setting of Windows-specific XML information, such as
96 architecture, system root, and version details. This information is now
97 automatically set in newly captured WIM images, when appropriate.
99 Improved performance of directory tree scans on Windows.
101 On Windows, to improve capture performance, wimlib now sometimes opens
102 files by inode number rather than by path. This is enabled for
103 wimcapture and wimappend, but for now other applications have to opt-in.
105 The progress messages printed by wimlib-imagex while writing WIM files
106 have been slightly tweaked.
108 Progress information for directory tree scans now counts all hard links.
109 Also, on Windows "\\?\" is no longer stripped from the current path.
111 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
112 'wiminfo'. This option lets you assign values to elements in a WIM
113 file's XML document by name.
115 The wimlib_get_image_property() and wimlib_set_image_property() API
116 functions now support numerically indexed elements.
118 Fixed a bug where, on Windows, wimlib would change the security
119 descriptor of the target directory of an extraction even when the
120 '--no-acls' option was specified.
123 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
124 some Microsoft software would not correctly recognize data in the
125 resulting filesystem.
127 Made some small improvements to the compression algorithms:
128 LZX compression ratio was slightly improved.
129 XPRESS compression ratio and speed was slightly improved.
130 LZMS compression speed was slightly improved.
132 Improved handling of WIM XML data. wimlib no longer drops unrecognized
133 elements when exporting images. In addition, two API functions were
134 added for better access to elements in the XML document:
135 wimlib_get_image_property() and wimlib_set_image_property().
137 Added support for (unsafe) in-place compaction of WIM files.
139 Improved performance of image export by reusing metadata resources
140 instead of always rebuilding and recompressing them.
142 Improved performance of wimlib_update_image() by delaying the update to
143 the WIM's XML document until a write is requested.
145 On Windows, the target of an extraction may now be a reparse point
146 (which will be dereferenced).
148 On Windows, wimlib now correctly restores non-Microsoft reparse points.
149 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
151 On Windows, wimlib now has improved performance when archiving files
152 from a filesystem backed by a WIM (a "WIMBoot" setup).
154 Several improvements to System Compression (compact mode) support:
156 wof.sys (or wofadk.sys) is now automatically attached to the
157 target volume if needed.
159 Compact-mode extractions now work correctly with wofadk.sys on
160 older versions of Windows.
162 For compatibility with the Windows bootloader, the requested
163 compression format now is overridden on certain files.
165 Other minor bugfixes.
168 This release primarily contains various minor bug fixes and
169 improvements, including:
171 Improved handling of deep directory structures.
173 Fixed a bug where on 32-bit systems, the library could enter an
174 infinite loop if a WIM file was malformed in a specific way.
176 Added a workaround for a case where libntfs-3g may report
177 duplicate streams in an NTFS file.
179 Windows symbolic links and junctions in mounted WIM images are
180 now automatically rewritten to be valid in the mounted location.
182 Reparse point fixes: correctly handle the "ReparseReserved"
183 field, and correctly handle "empty" (data-less) reparse points.
185 On Windows, wimlib now acquires SeManageVolumePrivilege, which
186 is needed to create externally backed files using the
189 Improved validation of filenames.
191 Improved LZMS decompression speed.
193 The configure script now honors alternate pkg-config settings.
195 Links have been updated to point to the new website.
197 In addition, experimental support has been added for compressing
198 extracted files using System Compression on Windows 10. This
199 functionality is available through the new '--compact' option to
200 'wimapply' and 'wimextract' as well as new library flags.
203 Fixed a bug in the LZX decompressor: malicious input data could cause
204 out of bounds writes to memory (since wimlib v1.2.2).
206 The output of the 'wiminfo' command now consolidates various boolean
207 flags (such as "Relative path junction") into a single line.
209 A file can now have both an unnamed data stream ("file contents") and a
210 reparse point stream. Such files can exist as a result of the use of
211 certain Windows features, such as offline storage, including "OneDrive".
212 wimlib will now store and restore both streams on Windows as well as in
213 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
215 On Windows, named data streams of encrypted files are no longer stored
216 twice in WIM archives.
218 On Windows, named data streams are now correctly extracted to existing
219 "readonly" directories. Before, an error would be reported.
221 On Windows, it is now possible to do a "WIMBoot mode" extraction with
222 non-standalone WIMs such as delta WIMs.
224 On Windows, when doing an extraction in "WIMBoot mode", files larger
225 than 4 gigabytes are now never extracted as externally backed. This
226 works around a bug in Microsoft's "WOF" driver.
228 The '--enable-verify-compression' configure option has been removed. If
229 you want to verify a WIM file, use the 'wimverify' program.
231 The way the "file count", "directory count", "total bytes", and "hard
232 link bytes" image statistics (stored in the WIM XML data) is calculated
233 has been slightly changed.
235 In mounted WIM images, the disk usage provided for each file (st_blocks)
236 is now the compressed size rather than the uncompressed size.
238 The performance of the NTFS-3g and Windows capture modes has been
241 On UNIX-like systems, symbolic links whose targets contain the backslash
242 character are now handled correctly (losslessly).
245 Improved the LZX compressor. It is now 15-20% faster than before and
246 provides a slightly better compression ratio.
248 Improved the LZMS compressor. It now provides a compression ratio
249 slightly better than WIMGAPI while still being faster and using slightly
252 The compression chunk size in solid resources, e.g. when capturing or
253 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
254 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
255 better compression ratio and is the same value that WIMGAPI uses. The
256 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
257 lower than WIMGAPI's memory usage, but if it is too much, it is still
258 possible to choose a lower value, e.g. with the '--solid-chunk-size'
259 option to wimlib-imagex.
261 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
262 accept the 'K', 'M', and 'G' suffixes.
264 Files are now sorted by name extension when creating a solid WIM file.
266 Fixed various issues related to capture/apply of EFS-encrypted files on
269 The file list printed by 'wimdir' is now sorted by the platform-specific
270 case sensitivity setting, rather than always case sensitively. This
271 also affects the library function wimlib_iterate_dir_tree().
273 On Windows, some error and warning messages have been improved.
276 The Windows binary distribution no longer contains third party DLLs.
277 These dependencies are instead compiled directly into the libwim DLL.
279 Added more fixes for wimlib on non-x86 architectures such as ARM.
281 Extracting files to a Windows PE in-memory filesystem no longer fails if
282 the target files do not yet exist.
284 Improved the performance of XPRESS compression and LZMS decompression.
286 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
287 It will automatically be faster on newer Intel and AMD processors.
289 Removed the --with-imagex-progname and --enable-more-assertions
293 Fix for very slow export from solid WIM / ESD files.
295 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
297 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
298 may use this to treat some types of errors as non-fatal.
300 The library now permits making in-memory changes to a WIMStruct backed
301 by a read-only WIM file.
303 Fixes for "WIMBoot" extraction mode (Windows only):
305 When not using the WOF driver, extraction no longer fails if the
306 disk containing the WIM file has too many partitions.
308 When matching patterns in [PrepopulateList], all hard links of
309 each file are now considered.
311 The system registry files are now automatically treated as being
312 in [PrepopulateList].
314 Added a hack to try to work around an intermittent bug in
315 Microsoft's WOF (Windows Overlay Filesystem) driver.
318 Made more improvements to the XPRESS, LZX, and LZMS compressors.
320 A number of improvements to the Windows port:
322 Fixes for setting short filenames.
324 Faster "WIMBoot" extraction.
326 Updated and slimmed down the dependent DLLs.
328 ACL inheritence bits are now restored.
330 Mandatory integrity labels are now backed up and restored.
332 Added a workaround for an issue where in rare cases, wimlib could create
333 a compressed data stream that could not be read correctly by Windows
334 after an extraction in "WIMBoot" mode.
337 Added file count progress data for
338 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
339 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
341 Added support for testing file exclusions via the user-provided
344 Some documentation improvements.
346 Made some clarifications to the license text in the COPYING file.
349 Made more improvements to the XPRESS, LZX, and LZMS compressors.
351 The default compression mode for wimcapture is now LZX compression in
352 its default mode, which is the same as '--compress=maximum'.
354 You can now specify an optional integer compression level to the
355 '--compress' option; e.g. '--compress=lzx:75'.
357 Made a minor change to the LZMS compressor and decompressor to fix an
358 incompatibility with the Microsoft implementation. In the unlikely
359 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
360 earlier and a checksum error is reported when extracting files from it
361 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
364 Added 'verify' subcommand to wimlib-imagex.
366 Notable library changes:
368 Custom compressor parameters have been removed from the library
369 in favor of the simpler level-based API.
371 Decompressor parameters have been removed entirely.
373 Library users can now specify a custom file for warning and
374 error messages to be sent to, rather than the default of
377 New progress messages:
378 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
379 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
381 New function: wimlib_verify_wim().
384 Improved compression, decompression, and extraction performance.
386 Improved compatibility with version 3584 WIM / ESD files:
387 - Add support for reading and writing multiple solid blocks per
388 archive, which WIMGAPI/DISM can create when appending an image.
389 - Correctly create solid blocks larger than 4 GiB.
391 'add' commands passed to wimupdate will now replace existing
392 nondirectory files by default. Use the --no-replace option to get the
395 The license for the library now contains an exception that allows using
396 it under the LGPL. See the COPYING file for details.
398 In reparse-point fixup mode (the default for capture), symbolic links
399 and junctions that point outside the tree being captured are no longer
400 excluded from capture.
402 Added support for "WIMBoot" capture and extraction. See the
403 documentation for the new '--wimboot' option to wimcapture and wimapply
404 for more information.
406 On UNIX-like systems, you can now backup and restore device nodes, named
407 pipes, and sockets. In addition, 32-bit user and group IDs are now
410 The way that UNIX data is stored in WIM files has been changed. If you
411 captured any WIMs with the --unix-data option, to upgrade them you'll
412 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
413 re-capture them with --unix-data using this version.
415 wimlib now understands tagged metadata items, such as object IDs, that
416 can be stored in WIM directory entries.
418 Removed the --hardlink and --symlink options to wimapply, since I don't
419 think they are too useful and they got in the way of improving the code.
421 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
423 The 'mkwinpeimg' script now supports writing the ISO image to standard
426 The <ARCH> element in WIM XML data is now exported correctly.
428 On Windows, sparse file attributes are no longer set on extracted files.
429 Oddly enough, this actually saves disk space in some cases.
431 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
432 supported. Mounting WIM images now always requires extended attribute
433 support. Use --without-fuse to disable support for mounting WIM images;
434 this will also disable the need for extended attribute support.
436 Configuring with --enable-ssse3-sha1 now works correctly.
438 The shared library version has been bumped up. The main
439 incompatibilities are:
441 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
442 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
445 - User-provided progress functions are now registered using a
446 separate function, wimlib_register_progress_function(). The
447 'progress_func' argument to many functions no longer exists.
449 - The return value from user-provided progress functions is now
452 - A context argument has been added to the prototype of
453 user-provided progress functions.
455 - 'struct wimlib_capture_config' has been removed. The library
456 now takes the path to the configuration file directly. This
457 affects wimlib_add_image(), wimlib_add_image_multisource(),
458 and wimlib_update_image(). However, a NULL value passed in
459 the argument retains the same meaning.
461 - Removed deprecated functions: some (de)compression functions,
462 wimlib_extract_files(), and wimlib_print_metadata().
464 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
465 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
466 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
468 - Removed some progress messages:
469 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
470 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
471 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
474 - Removed some error codes. Numbering stays the same.
476 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
477 WIMLIB_UNMOUNT_FLAG_FORCE.
479 - WIM paths passed to progress functions now have a leading
483 Case-insensitive comparisons of strings (e.g. filenames) containing
484 UTF-16 codepoints above 32767 are now done correctly.
486 Fixed build failure on Mac OS X.
488 wimunmount now provides the '--new-image' option to cause changes to a
489 read-write mounted image to be committed as a new image rather than as
490 an update of the mounted image. (The corresponding new library flag is
491 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
493 The LZMS ("recovery") compression chunk size, or "dictionary size", may
494 now be up to 1 GiB (1,073,741,824 bytes).
496 The performance of LZX ("maximum") and LZMS ("recovery") compression
497 with large chunk sizes has been slightly improved.
500 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
501 decompressed correctly.
503 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
504 occurred in an unlikely case, and due to validity checks it did not
505 affect successfully created archives.
507 Fixed a minor compatibility issue with the LZMS compressor and
508 decompressor. This is *not* the default compression type and was only
509 introduced in v1.6.0. In the unlikely event that you created an
510 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
511 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
514 Memory usage for LZMS and LZX compression has been decreased.
516 wimextract now allows wildcard characters in paths specified on the
517 command line. Also, the '--strict-wildcards' option has been removed
518 and replaced with the inverse option '--nullglob'. See the
519 documentation for wimextract for more details and changes.
521 The wimlib_extract_files() function is now considered deprecated in
522 favor of wimlib_extract_paths().
524 Fixed more permissions problems when extracting files on Windows.
526 A new '--no-attributes' option has been added to wimapply and
527 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
529 The default chunk size is now set correctly when changing the
530 compression type of a WIM, for example with 'wimoptimize'.
532 The '--metadata' option to wiminfo has been replaced with the
533 '--detailed' option to wimdir.
535 In relevant wimlib-imagex commands, '--solid' may now be used as an
536 alias for '--pack-streams'.
539 Support for extracting and updating the new version 3584 WIMs has been
540 added. These WIMs typically pack many streams ("files") together into a
541 single compressed resource, thereby saving space. This degrades the
542 performance of random access (such as that which occurs on a mounted
543 image), but optimizations have been implemented for extraction. These
544 new WIM files also typically use a new compression format (LZMS), which
545 is similar to LZMA and can offer a better compression ratio than LZX.
546 These new WIM files can be created using `wimcapture' with
547 the '--compress=lzms --pack-streams' options. Note: this new WIM format
548 is used by the Windows 8 web downloader, but important segments of the
549 raw '.esd' files are encrypted, so wimlib will not be able to extract
550 such files until they are first decrypted.
552 wimlib now supports extracting files and directories from a WIM image
553 based on a "listfile" that itself contains the list of paths to extract.
554 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
555 and for the library itself, the new APIs are wimlib_extract_pathlist()
556 and wimlib_extract_paths(). Path globs containing wildcard characters
559 For searching WIM files, wimlib now has configurable case sensitivity.
560 The default on Windows is still case-insensitive and the default on
561 UNIX-like systems is still case-sensitive, but this can be overridden
562 on either platform through flags to wimlib_global_init(). For
563 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
564 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
567 Support for compression chunk sizes greater than the default of 32768
568 bytes has been added. A larger chunk size typically results in a better
569 compression ratio. However, the MS implementation is seemingly not
570 compatible with all chunk sizes, especially for LZX compression, so the
571 defaults remain unchanged, with the exception of the new LZMS-compressed
572 WIMs, which use a larger chunk size by default.
574 The compression/decompression API exported by wimlib has been changed.
575 Now one set of functions handles all supported compression formats.
577 `wimcapture' and `wimappend' will now display the progress of scanning
578 the directory tree to capture, in addition to the progress of writing
579 data to the WIM. The '--verbose' option no longer does anything. The
580 library API change for this is the addition of several members to
581 `struct wimlib_progress_info_scan' available to progress callbacks.
583 `mkwinpeimg' now correctly handles the '--start-script' option when the
584 start script is not in the working directory.
586 Sequential extraction, previously requested by using
587 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
588 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
589 behavior (extract in file order).
592 The new LZX compressor added in v1.5.2 has been improved and is now
593 enabled by default, except when `wimcapture' or `wimappend' is run
594 *without* the '--compress' option, in which case the faster LZX
595 compressor is used (the same as before). This behavior is reasonably
596 consistent with ImageX which actually uses "fast" (XPRESS) compression
597 by default. In those cases, use '--compress=maximum' to explicitly
598 capture a WIM image using the new (slower but better) LZX compressor.
600 The '--compress-slow' option still exists to `wimlib-imagex optimize',
601 but its new behavior is to tweak the new LZX compressor even more to
602 produce an even better compression ratio at the cost of more time spent
605 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
606 which recompresses the WIM file using the specified compression TYPE.
607 The new library API function used for this is
608 wimlib_set_output_compression_type().
610 Added the wimlib_get_xml_data() function to allow library clients to
611 easily retrieve the raw XML data from a WIM file if needed.
613 Fixed a bug that could cause an error code to be incorrectly returned
614 when writing XML data containing a <WINDOWS> element.
616 Mounted WIM images will now correctly show the default file stream even
617 if appears in the alternate data stream entries of the corresponding WIM
621 Added a new experimental LZX compressor which can be enabled by passing
622 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
623 optimize'. (The latter is only applicable if the WIM is already
624 LZX-compressed and the '--recompress' option is also given.) The
625 experimental compressor is much slower but compresses the data slightly
626 more --- currently usually to within a fraction of a percent of the
627 results from WIMGAPI/ImageX.
629 A workaround has been added for compatibility with versions of WinPE
630 that interpret alternate data stream entries in the boot WIM
633 An alignment bug that caused a crash in the LZX decompressor on some
636 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
637 the WIM header when restoring the previous state of a WIM it failed to
640 Added a workaround to avoid an access denied error on Windows when
641 replacing a WIM file that another process has opened.
644 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
645 needed to be handled.
647 A bug in the interpretation of negative IMAGE indices in the
648 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
649 `wimlib-imagex append' has been fixed.
651 A workaround has been added to successfully apply security descriptors
652 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
653 2013.1.13 or earlier.
655 `wimlib-imagex capture' can now accept the '--delta-from' option
659 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
660 to standard output and applying images from standard input, but they are
661 not compatible with Microsoft's software and are not created by default.
662 See the documentation for --pipable flag of `wimlib-imagex capture' for
665 To better support incremental backups, added support for declaring an
666 image as a modified form of another image. See the documentation for
667 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
670 Added supported for "delta" WIMs. See the documentation for the
671 '--delta-from' option of `wimlib-imagex capture'.
673 The library support for managing split WIMs has been changed to support
674 other arrangements, such as delta WIMs, and be easier to use. This
675 change is visible in `wimlib-imagex', which also can now accept the
676 '--ref' option multiple times, and also now supports "delta" WIMs as
679 wimlib now preserves WIM integrity tables by default, even if
680 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
681 behavior of `wimlib-imagex' whenever the WIM being operated on contains
682 an integrity table and the '--check' option is not specified.
684 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
685 (when --compress is not specified). This provides the best compression
686 ratio by default, which is usually what is desired, at a cost of some
689 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
690 is the command as in `wimlib-imagex COMMAND'; for example, it can be
691 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
692 appropriate hard links are created in UNIX installations of
693 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
694 batch files that emulate this behavior are generated.
696 Security descriptors are now extracted correctly on Windows.
698 Fixed archiving DOS names in NTFS-3g capture mode.
700 The extraction code has been rewritten and it will now be easier to
701 support new features on all supported backends (currently Win32, UNIX,
702 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
703 now supported on all backends, not just UNIX.
705 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
706 than the WAIK itself.
708 wimlib_global_init() now, by default, attempts to acquire additional
709 privileges on Windows, so library clients need not do this.
711 This update bumps the shared library version number up to 9, since it is
712 not binary compatibible with previous releases.
715 Fixed bug in `wimlib-imagex export' that made it impossible to export an
716 image from a WIM that is readonly at the filesystem level.
718 Return error code rather than segfaulting when trying to list files from
719 a non-first part of a split WIM.
721 Joining a WIM will now preserve the RP_FIX and READONLY flags.
724 On Windows, paths given to wimlib-imagex are now treated case
727 Improved behavior regarding invalid filenames; in particular, on
728 Windows, wimlib-imagex will, when extracting, now omit (with an option
729 to override this default) filenames differing only in case, or filenames
730 containing characters not valid on Windows.
732 On Windows, wimlib now supports capturing and extracting long paths
733 (longer than the so-called MAX_PATH).
735 On Windows, `wimlib-imagex update' now acquires proper privileges when
736 running as an Administrator.
738 `wimlib-imagex update' will now complain if no image is specified when
739 trying to update a multi-image WIM.
741 `wimlib-imagex update' now supports specifying a single update command
742 directly on the command line using the --command option.
744 wimlib-imagex will now choose different units for progress messages,
745 depending on the amount of data that needs to be processed.
747 `wimlib-imagex append' will now generate a unique WIM image name if no
748 name is specified and the defaulted name already exists in the WIM.
750 wimlib now allows you to create unnamed WIM images, which can then only
751 be referred to by index.
753 wimlib now allows you to explicitly declare you want write access to a
754 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
757 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
760 Progress callbacks have been added to wimlib's wimlib_update_image()
763 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
764 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
767 NTFS-3g capture now only warns about two conditions previously treated
770 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
773 wimlib now correctly detects and returns an error when reading a WIM
774 image with a cyclic directory structure. (Fun fact: such a WIM will
775 crash Microsoft's software.)
778 Added new "extract" and "update" subcommands to wimlib-imagex, along
779 with associated APIs in the library. These commands are intended mainly
780 for Windows use but can be used on UNIX as well.
782 Many documentation improvements.
784 Fixed a bug in the Windows build where relative symbolic links were not
785 captured in reparse-point fixup mode.
787 Fixed a bug in the Windows build where file handles were left open to
788 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
790 Fixed a bug in the Windows build of wimlib-imagex where globbing
791 split-WIM parts could cause the program to crash.
793 Fixed a bug where the creation time of WIM images would be shown instead
794 of the last modification time.
796 With the Windows build it is now possible to restore a WIM containing
797 symbolic links as a non-Administrator; however you will receive warnings
798 about not being able to extract the symbolic links.
801 Capturing a WIM image should now be significantly faster in most cases
802 due to improved use of the operating system's cache and avoiding reading
803 files twice whenever possible.
805 The Windows build should now work on Windows XP.
807 The Windows build now supports capturing and restoring hidden,
808 compressed, sparse, and encrypted files.
810 The Windows build now supports capturing and applying WIM images from
811 filesystems other than NTFS (with some reduced functionality).
813 The Windows build now extracts short names correctly.
815 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
816 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
817 capture' and `wimlib-imagex apply'.
819 The performance of splitting and joining WIMs should be slightly
822 The LZX and XPRESS compression and decompression functions are now
823 exported from the library.
826 Improvements and bugfixes for the Windows build.
828 Added --strict-acls options.
830 Fixed the way that wimlib determines the order of images in the WIM.
833 Since wimlib can now be used on Windows, wimlib's implementation of
834 ImageX has been renamed to wimlib-imagex to avoid confusion with
835 Microsoft's implementation of ImageX, which would have the same file
836 name ("imagex.exe"). If you really don't like this you can pass the
837 --with-imagex-progname option to `configure' to choose a different name,
838 or even simply rename the binary yourself (but the former way will
839 configure the man pages to use the chosen name).
841 Various bugs fixed in the Windows build. Mainly to do with capturing
842 and restoring alternate data streams correctly in weird cases, and
843 requesting the correct privileges when opening files. Also added the
844 --noacls options to wimlib-imagex capture, append, and apply.
846 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
847 dynamically loaded, so this may make the library compatible with Windows
848 XP (however, there may still be other problems).
851 Added experimental support for native Windows builds. Binaries can be
852 downloaded from the SourceForge page.
854 --source-list option added to `imagex capture' and `imagex append'.
856 Better support for different character encodings.
859 Storing UNIX file owners, groups, and modes in WIM images is now
860 possible using `imagex capture' with the --unix-data flag.
862 Minor bug fixes and documentation fixes.
865 NTFS capture: Fixed capturing duplicate reparse points.
867 NTFS capture: Capture first unnamed stream if there are more than one
868 (print warning instead of error).
870 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
873 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
876 Update to work with ntfs-3g version 2013.1.13.
879 Fixed truncating file to shorter but non-zero length on read-write
882 Various code cleanups and minor documentation fixes.
885 LZX and XPRESS decompression have received some additional optimizations
886 and should now be even faster. (Although, they were already pretty
887 fast--- much faster than typical I/O speeds.)
889 Fixed a bug introduced in v1.2.1 that would cause a directory tree
890 containing hard links to be captured incorrectly in some cases.
893 By default, unmounting a read-write mounted WIM with 'imagex unmount
894 --commit' will now change the WIM in-place without needing to write the
895 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
898 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
899 for a response from the daemon servicing the mounted WIM. Instead,
900 every second 'imagex unmount' will check if the daemon is still alive,
901 and keep waiting if so, otherwise terminate with an error.
903 'imagex unmount --commit' on a read-write mounted WIM will now print
904 progress information regarding the writing of new or modified streams
905 the WIM, just like when capturing or appending a WIM.
907 A small change has been made to XPRESS compression and it should improve
908 the compression ratio slightly.
910 A change was made that may improve performance slightly when applying a
911 WIM image to a NTFS volume.
913 Microsoft has managed to introduce even more bugs into their software,
914 and now the WIMs for Windows 8 have incorrect (too low) reference counts
915 for some streams. This is unsafe because such streams can be removed
916 when they are in actuality still referenced in the WIM (perhaps by a
917 different image). wimlib will now work around this problem by fixing
918 the stream reference counts. This is only done when wimlib_delete_image() is
919 called ('imagex delete') or when wimlib_mount_image() is called with
920 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
921 requires reading the metadata for all images in the WIM, so this will
922 make these operations noticably slower on WIMs with multiple images.
924 Various other bugfixes.
927 Appending images to a WIM is now be done by default without re-building
928 the whole WIM. Use the --rebuild flag to get the old behavior (which
929 was to re-build the entire WIM when a new image is appended).
931 A new command `imagex optimize' is now available to manually re-build a
932 WIM that has wasted space due to repeated appends.
934 Progress information has been improved, and now arbitrary callback
935 functions can be used to show the progress of a WIM operation.
937 A possible bug with changing the bootable image of a WIM was fixed.
939 Some advisory locking is now done to prevent two processes from
940 modifying a WIM at the same time (but only in some cases). For example,
941 you cannot mount two images from a WIM read-write at the same time.
943 Some functions have been reorganized:
944 * wimlib_mount() renamed to wimlib_mount_image().
945 * wimlib_unmount() renamed to wimlib_unmount_image().
946 * wimlib_overwrite_xml_and_header() removed as
947 wimlib_overwrite() suffices now.
948 * wimlib_apply_image_to_ntfs_volume() removed as
949 wimlib_extract_image() suffices now.
950 * wimlib_add_image_from_ntfs_volume() removed as
951 * wimlib_add_image() suffices now.
953 Previously, the soname of libwim.so has been 0.0.0, despite many
954 interface changes. The soname is now updated to 1.0.0 and will now be
955 updated each release.
958 Resources will now be compressed using multiple threads by default.
959 (This applies to `imagex capture', `imagex append', and `imagex
962 Some performance improvements in mounted WIMs.
964 More progress information is shown when capturing a WIM.
967 Lots of minor fixes, code cleanups, and some documentation updates.
968 Nothing in particular is really noteworthy.
971 LZX and XPRESS compression improvements.
973 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
974 Link Bytes of the WIM.
977 Fixed bug when capturing NTFS file with multiple named data streams.
979 Internally, we are now using inode structures, even though these don't
980 appear literally in the WIM file. This simplifies some of the code
981 (mainly for WIM mounting) and likely fixed a few problems, although it
985 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
989 Enough changes to call it version 1.0.0!
991 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
992 to a NTFS volume, is now supported.
994 Hard links and symbolic links have much improved support. They are
995 supported for WIM capture, WIM application, and mounted WIMs (you can
996 even make them on read-write mounted WIMs).
998 Alternate data streams are now supported on mounted WIMs through an
999 xattr or a Windows-style stream interface. Also they are supported when
1000 capturing a WIM from NTFS or applying a WIM to NTFS.
1002 Split WIMs are better supported. You may now apply an image directly
1003 from a split WIM, mount an image from a split WIM read-only, or export
1004 an image from a split WIM.
1006 Using a capture configuration file is now supported (but not fully yet).
1008 SHA1 message digests are checked in more places, so we can make sure
1009 applied and captured data is correct.
1011 Man pages have been updated and consolidated.
1014 Fixed segfault when unmounting read-only WIM.
1017 Support for joining and splitting WIMs.
1018 Also, security data is now preserved by default.
1021 Can now build with older gcc and system headers, like on CentOS 5.
1024 Fixed bug that made it impossible to overwrite files in read-write
1028 Write byte-order mark before WIM XML data. (imagex.exe requires this to
