2 The LZX compression ratio has been slightly improved. The default mode,
3 LZX level 50, is now almost as good as the old LZX level 100, while
4 being nearly the same speed as before.
6 Decompression performance has been slightly improved.
8 Filenames are now always listed in NTFS collation order.
10 On UNIX-like systems, wimlib can now process Windows filenames that are
11 not valid Unicode due to the presence of unpaired surrogates.
13 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
14 addition of surrogate codepoints. Consequently, the environmental
15 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
16 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
18 wimlib no longer depends on iconv.
20 Reduced memory usage slightly.
22 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
23 been removed. Users are advised to upgrade to a later version of
27 On UNIX, wimlib can now overwrite readonly files when extracting.
29 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
30 NTFS permissions") set on some existing directories after extraction.
32 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
33 driver is not loaded, wimlib can now correctly register a new WIM file
34 with the target volume when the target volume previously had had WIM
37 Added a new testing program.
39 Clarified the main license text and updated public domain dedications
40 for certain files to be more thorough.
43 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
45 Reduced memory usage when exporting large numbers of WIM images.
47 Non UTF-8 locales are now detected correctly.
49 Addressed compiler warnings and enabled "silent" make rules by default.
51 Windows-specific updates:
52 Fixed a bug where duplicate backslashes could be generated in
53 link targets when extracting symbolic links and junctions.
55 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
56 work if their full path contained a space.
58 Fixed bugs related to scanning SMB filesystems.
60 Added warning message about known issue with WindowsApps folder.
62 Added instructions for building from source on Windows.
64 VSS support is no longer marked "experimental".
66 Added missing license file for libdivsufsort-lite.
69 Added experimental support for Windows VSS (Volume Shadow Copy Service).
70 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
71 create and use a temporary VSS snapshot when capturing a WIM image.
73 Implemented setting of Windows-specific XML information, such as
74 architecture, system root, and version details. This information is now
75 automatically set in newly captured WIM images, when appropriate.
77 Improved performance of directory tree scans on Windows.
79 On Windows, to improve capture performance, wimlib now sometimes opens
80 files by inode number rather than by path. This is enabled for
81 wimcapture and wimappend, but for now other applications have to opt-in.
83 The progress messages printed by wimlib-imagex while writing WIM files
84 have been slightly tweaked.
86 Progress information for directory tree scans now counts all hard links.
87 Also, on Windows "\\?\" is no longer stripped from the current path.
89 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
90 'wiminfo'. This option lets you assign values to elements in a WIM
91 file's XML document by name.
93 The wimlib_get_image_property() and wimlib_set_image_property() API
94 functions now support numerically indexed elements.
96 Fixed a bug where, on Windows, wimlib would change the security
97 descriptor of the target directory of an extraction even when the
98 '--no-acls' option was specified.
101 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
102 some Microsoft software would not correctly recognize data in the
103 resulting filesystem.
105 Made some small improvements to the compression algorithms:
106 LZX compression ratio was slightly improved.
107 XPRESS compression ratio and speed was slightly improved.
108 LZMS compression speed was slightly improved.
110 Improved handling of WIM XML data. wimlib no longer drops unrecognized
111 elements when exporting images. In addition, two API functions were
112 added for better access to elements in the XML document:
113 wimlib_get_image_property() and wimlib_set_image_property().
115 Added support for (unsafe) in-place compaction of WIM files.
117 Improved performance of image export by reusing metadata resources
118 instead of always rebuilding and recompressing them.
120 Improved performance of wimlib_update_image() by delaying the update to
121 the WIM's XML document until a write is requested.
123 On Windows, the target of an extraction may now be a reparse point
124 (which will be dereferenced).
126 On Windows, wimlib now correctly restores non-Microsoft reparse points.
127 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
129 On Windows, wimlib now has improved performance when archiving files
130 from a filesystem backed by a WIM (a "WIMBoot" setup).
132 Several improvements to System Compression (compact mode) support:
134 wof.sys (or wofadk.sys) is now automatically attached to the
135 target volume if needed.
137 Compact-mode extractions now work correctly with wofadk.sys on
138 older versions of Windows.
140 For compatibility with the Windows bootloader, the requested
141 compression format now is overridden on certain files.
143 Other minor bugfixes.
146 This release primarily contains various minor bug fixes and
147 improvements, including:
149 Improved handling of deep directory structures.
151 Fixed a bug where on 32-bit systems, the library could enter an
152 infinite loop if a WIM file was malformed in a specific way.
154 Added a workaround for a case where libntfs-3g may report
155 duplicate streams in an NTFS file.
157 Windows symbolic links and junctions in mounted WIM images are
158 now automatically rewritten to be valid in the mounted location.
160 Reparse point fixes: correctly handle the "ReparseReserved"
161 field, and correctly handle "empty" (data-less) reparse points.
163 On Windows, wimlib now acquires SeManageVolumePrivilege, which
164 is needed to create externally backed files using the
167 Improved validation of filenames.
169 Improved LZMS decompression speed.
171 The configure script now honors alternate pkg-config settings.
173 Links have been updated to point to the new website.
175 In addition, experimental support has been added for compressing
176 extracted files using System Compression on Windows 10. This
177 functionality is available through the new '--compact' option to
178 'wimapply' and 'wimextract' as well as new library flags.
181 Fixed a bug in the LZX decompressor: malicious input data could cause
182 out of bounds writes to memory (since wimlib v1.2.2).
184 The output of the 'wiminfo' command now consolidates various boolean
185 flags (such as "Relative path junction") into a single line.
187 A file can now have both an unnamed data stream ("file contents") and a
188 reparse point stream. Such files can exist as a result of the use of
189 certain Windows features, such as offline storage, including "OneDrive".
190 wimlib will now store and restore both streams on Windows as well as in
191 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
193 On Windows, named data streams of encrypted files are no longer stored
194 twice in WIM archives.
196 On Windows, named data streams are now correctly extracted to existing
197 "readonly" directories. Before, an error would be reported.
199 On Windows, it is now possible to do a "WIMBoot mode" extraction with
200 non-standalone WIMs such as delta WIMs.
202 On Windows, when doing an extraction in "WIMBoot mode", files larger
203 than 4 gigabytes are now never extracted as externally backed. This
204 works around a bug in Microsoft's "WOF" driver.
206 The '--enable-verify-compression' configure option has been removed. If
207 you want to verify a WIM file, use the 'wimverify' program.
209 The way the "file count", "directory count", "total bytes", and "hard
210 link bytes" image statistics (stored in the WIM XML data) is calculated
211 has been slightly changed.
213 In mounted WIM images, the disk usage provided for each file (st_blocks)
214 is now the compressed size rather than the uncompressed size.
216 The performance of the NTFS-3g and Windows capture modes has been
219 On UNIX-like systems, symbolic links whose targets contain the backslash
220 character are now handled correctly (losslessly).
223 Improved the LZX compressor. It is now 15-20% faster than before and
224 provides a slightly better compression ratio.
226 Improved the LZMS compressor. It now provides a compression ratio
227 slightly better than WIMGAPI while still being faster and using slightly
230 The compression chunk size in solid resources, e.g. when capturing or
231 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
232 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
233 better compression ratio and is the same value that WIMGAPI uses. The
234 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
235 lower than WIMGAPI's memory usage, but if it is too much, it is still
236 possible to choose a lower value, e.g. with the '--solid-chunk-size'
237 option to wimlib-imagex.
239 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
240 accept the 'K', 'M', and 'G' suffixes.
242 Files are now sorted by name extension when creating a solid WIM file.
244 Fixed various issues related to capture/apply of EFS-encrypted files on
247 The file list printed by 'wimdir' is now sorted by the platform-specific
248 case sensitivity setting, rather than always case sensitively. This
249 also affects the library function wimlib_iterate_dir_tree().
251 On Windows, some error and warning messages have been improved.
254 The Windows binary distribution no longer contains third party DLLs.
255 These dependencies are instead compiled directly into the libwim DLL.
257 Added more fixes for wimlib on non-x86 architectures such as ARM.
259 Extracting files to a Windows PE in-memory filesystem no longer fails if
260 the target files do not yet exist.
262 Improved the performance of XPRESS compression and LZMS decompression.
264 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
265 It will automatically be faster on newer Intel and AMD processors.
267 Removed the --with-imagex-progname and --enable-more-assertions
271 Fix for very slow export from solid WIM / ESD files.
273 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
275 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
276 may use this to treat some types of errors as non-fatal.
278 The library now permits making in-memory changes to a WIMStruct backed
279 by a read-only WIM file.
281 Fixes for "WIMBoot" extraction mode (Windows only):
283 When not using the WOF driver, extraction no longer fails if the
284 disk containing the WIM file has too many partitions.
286 When matching patterns in [PrepopulateList], all hard links of
287 each file are now considered.
289 The system registry files are now automatically treated as being
290 in [PrepopulateList].
292 Added a hack to try to work around an intermittent bug in
293 Microsoft's WOF (Windows Overlay Filesystem) driver.
296 Made more improvements to the XPRESS, LZX, and LZMS compressors.
298 A number of improvements to the Windows port:
300 Fixes for setting short filenames.
302 Faster "WIMBoot" extraction.
304 Updated and slimmed down the dependent DLLs.
306 ACL inheritence bits are now restored.
308 Mandatory integrity labels are now backed up and restored.
310 Added a workaround for an issue where in rare cases, wimlib could create
311 a compressed data stream that could not be read correctly by Windows
312 after an extraction in "WIMBoot" mode.
315 Added file count progress data for
316 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
317 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
319 Added support for testing file exclusions via the user-provided
322 Some documentation improvements.
324 Made some clarifications to the license text in the COPYING file.
327 Made more improvements to the XPRESS, LZX, and LZMS compressors.
329 The default compression mode for wimcapture is now LZX compression in
330 its default mode, which is the same as '--compress=maximum'.
332 You can now specify an optional integer compression level to the
333 '--compress' option; e.g. '--compress=lzx:75'.
335 Made a minor change to the LZMS compressor and decompressor to fix an
336 incompatibility with the Microsoft implementation. In the unlikely
337 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
338 earlier and a checksum error is reported when extracting files from it
339 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
342 Added 'verify' subcommand to wimlib-imagex.
344 Notable library changes:
346 Custom compressor parameters have been removed from the library
347 in favor of the simpler level-based API.
349 Decompressor parameters have been removed entirely.
351 Library users can now specify a custom file for warning and
352 error messages to be sent to, rather than the default of
355 New progress messages:
356 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
357 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
359 New function: wimlib_verify_wim().
362 Improved compression, decompression, and extraction performance.
364 Improved compatibility with version 3584 WIM / ESD files:
365 - Add support for reading and writing multiple solid blocks per
366 archive, which WIMGAPI/DISM can create when appending an image.
367 - Correctly create solid blocks larger than 4 GiB.
369 'add' commands passed to wimupdate will now replace existing
370 nondirectory files by default. Use the --no-replace option to get the
373 The license for the library now contains an exception that allows using
374 it under the LGPL. See the COPYING file for details.
376 In reparse-point fixup mode (the default for capture), symbolic links
377 and junctions that point outside the tree being captured are no longer
378 excluded from capture.
380 Added support for "WIMBoot" capture and extraction. See the
381 documentation for the new '--wimboot' option to wimcapture and wimapply
382 for more information.
384 On UNIX-like systems, you can now backup and restore device nodes, named
385 pipes, and sockets. In addition, 32-bit user and group IDs are now
388 The way that UNIX data is stored in WIM files has been changed. If you
389 captured any WIMs with the --unix-data option, to upgrade them you'll
390 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
391 re-capture them with --unix-data using this version.
393 wimlib now understands tagged metadata items, such as object IDs, that
394 can be stored in WIM directory entries.
396 Removed the --hardlink and --symlink options to wimapply, since I don't
397 think they are too useful and they got in the way of improving the code.
399 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
401 The 'mkwinpeimg' script now supports writing the ISO image to standard
404 The <ARCH> element in WIM XML data is now exported correctly.
406 On Windows, sparse file attributes are no longer set on extracted files.
407 Oddly enough, this actually saves disk space in some cases.
409 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
410 supported. Mounting WIM images now always requires extended attribute
411 support. Use --without-fuse to disable support for mounting WIM images;
412 this will also disable the need for extended attribute support.
414 Configuring with --enable-ssse3-sha1 now works correctly.
416 The shared library version has been bumped up. The main
417 incompatibilities are:
419 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
420 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
423 - User-provided progress functions are now registered using a
424 separate function, wimlib_register_progress_function(). The
425 'progress_func' argument to many functions no longer exists.
427 - The return value from user-provided progress functions is now
430 - A context argument has been added to the prototype of
431 user-provided progress functions.
433 - 'struct wimlib_capture_config' has been removed. The library
434 now takes the path to the configuration file directly. This
435 affects wimlib_add_image(), wimlib_add_image_multisource(),
436 and wimlib_update_image(). However, a NULL value passed in
437 the argument retains the same meaning.
439 - Removed deprecated functions: some (de)compression functions,
440 wimlib_extract_files(), and wimlib_print_metadata().
442 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
443 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
444 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
446 - Removed some progress messages:
447 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
448 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
449 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
452 - Removed some error codes. Numbering stays the same.
454 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
455 WIMLIB_UNMOUNT_FLAG_FORCE.
457 - WIM paths passed to progress functions now have a leading
461 Case-insensitive comparisons of strings (e.g. filenames) containing
462 UTF-16 codepoints above 32767 are now done correctly.
464 Fixed build failure on Mac OS X.
466 wimunmount now provides the '--new-image' option to cause changes to a
467 read-write mounted image to be committed as a new image rather than as
468 an update of the mounted image. (The corresponding new library flag is
469 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
471 The LZMS ("recovery") compression chunk size, or "dictionary size", may
472 now be up to 1 GiB (1,073,741,824 bytes).
474 The performance of LZX ("maximum") and LZMS ("recovery") compression
475 with large chunk sizes has been slightly improved.
478 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
479 decompressed correctly.
481 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
482 occurred in an unlikely case, and due to validity checks it did not
483 affect successfully created archives.
485 Fixed a minor compatibility issue with the LZMS compressor and
486 decompressor. This is *not* the default compression type and was only
487 introduced in v1.6.0. In the unlikely event that you created an
488 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
489 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
492 Memory usage for LZMS and LZX compression has been decreased.
494 wimextract now allows wildcard characters in paths specified on the
495 command line. Also, the '--strict-wildcards' option has been removed
496 and replaced with the inverse option '--nullglob'. See the
497 documentation for wimextract for more details and changes.
499 The wimlib_extract_files() function is now considered deprecated in
500 favor of wimlib_extract_paths().
502 Fixed more permissions problems when extracting files on Windows.
504 A new '--no-attributes' option has been added to wimapply and
505 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
507 The default chunk size is now set correctly when changing the
508 compression type of a WIM, for example with 'wimoptimize'.
510 The '--metadata' option to wiminfo has been replaced with the
511 '--detailed' option to wimdir.
513 In relevant wimlib-imagex commands, '--solid' may now be used as an
514 alias for '--pack-streams'.
517 Support for extracting and updating the new version 3584 WIMs has been
518 added. These WIMs typically pack many streams ("files") together into a
519 single compressed resource, thereby saving space. This degrades the
520 performance of random access (such as that which occurs on a mounted
521 image), but optimizations have been implemented for extraction. These
522 new WIM files also typically use a new compression format (LZMS), which
523 is similar to LZMA and can offer a better compression ratio than LZX.
524 These new WIM files can be created using `wimcapture' with
525 the '--compress=lzms --pack-streams' options. Note: this new WIM format
526 is used by the Windows 8 web downloader, but important segments of the
527 raw '.esd' files are encrypted, so wimlib will not be able to extract
528 such files until they are first decrypted.
530 wimlib now supports extracting files and directories from a WIM image
531 based on a "listfile" that itself contains the list of paths to extract.
532 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
533 and for the library itself, the new APIs are wimlib_extract_pathlist()
534 and wimlib_extract_paths(). Path globs containing wildcard characters
537 For searching WIM files, wimlib now has configurable case sensitivity.
538 The default on Windows is still case-insensitive and the default on
539 UNIX-like systems is still case-sensitive, but this can be overridden
540 on either platform through flags to wimlib_global_init(). For
541 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
542 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
545 Support for compression chunk sizes greater than the default of 32768
546 bytes has been added. A larger chunk size typically results in a better
547 compression ratio. However, the MS implementation is seemingly not
548 compatible with all chunk sizes, especially for LZX compression, so the
549 defaults remain unchanged, with the exception of the new LZMS-compressed
550 WIMs, which use a larger chunk size by default.
552 The compression/decompression API exported by wimlib has been changed.
553 Now one set of functions handles all supported compression formats.
555 `wimcapture' and `wimappend' will now display the progress of scanning
556 the directory tree to capture, in addition to the progress of writing
557 data to the WIM. The '--verbose' option no longer does anything. The
558 library API change for this is the addition of several members to
559 `struct wimlib_progress_info_scan' available to progress callbacks.
561 `mkwinpeimg' now correctly handles the '--start-script' option when the
562 start script is not in the working directory.
564 Sequential extraction, previously requested by using
565 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
566 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
567 behavior (extract in file order).
570 The new LZX compressor added in v1.5.2 has been improved and is now
571 enabled by default, except when `wimcapture' or `wimappend' is run
572 *without* the '--compress' option, in which case the faster LZX
573 compressor is used (the same as before). This behavior is reasonably
574 consistent with ImageX which actually uses "fast" (XPRESS) compression
575 by default. In those cases, use '--compress=maximum' to explicitly
576 capture a WIM image using the new (slower but better) LZX compressor.
578 The '--compress-slow' option still exists to `wimlib-imagex optimize',
579 but its new behavior is to tweak the new LZX compressor even more to
580 produce an even better compression ratio at the cost of more time spent
583 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
584 which recompresses the WIM file using the specified compression TYPE.
585 The new library API function used for this is
586 wimlib_set_output_compression_type().
588 Added the wimlib_get_xml_data() function to allow library clients to
589 easily retrieve the raw XML data from a WIM file if needed.
591 Fixed a bug that could cause an error code to be incorrectly returned
592 when writing XML data containing a <WINDOWS> element.
594 Mounted WIM images will now correctly show the default file stream even
595 if appears in the alternate data stream entries of the corresponding WIM
599 Added a new experimental LZX compressor which can be enabled by passing
600 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
601 optimize'. (The latter is only applicable if the WIM is already
602 LZX-compressed and the '--recompress' option is also given.) The
603 experimental compressor is much slower but compresses the data slightly
604 more --- currently usually to within a fraction of a percent of the
605 results from WIMGAPI/ImageX.
607 A workaround has been added for compatibility with versions of WinPE
608 that interpret alternate data stream entries in the boot WIM
611 An alignment bug that caused a crash in the LZX decompressor on some
614 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
615 the WIM header when restoring the previous state of a WIM it failed to
618 Added a workaround to avoid an access denied error on Windows when
619 replacing a WIM file that another process has opened.
622 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
623 needed to be handled.
625 A bug in the interpretation of negative IMAGE indices in the
626 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
627 `wimlib-imagex append' has been fixed.
629 A workaround has been added to successfully apply security descriptors
630 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
631 2013.1.13 or earlier.
633 `wimlib-imagex capture' can now accept the '--delta-from' option
637 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
638 to standard output and applying images from standard input, but they are
639 not compatible with Microsoft's software and are not created by default.
640 See the documentation for --pipable flag of `wimlib-imagex capture' for
643 To better support incremental backups, added support for declaring an
644 image as a modified form of another image. See the documentation for
645 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
648 Added supported for "delta" WIMs. See the documentation for the
649 '--delta-from' option of `wimlib-imagex capture'.
651 The library support for managing split WIMs has been changed to support
652 other arrangements, such as delta WIMs, and be easier to use. This
653 change is visible in `wimlib-imagex', which also can now accept the
654 '--ref' option multiple times, and also now supports "delta" WIMs as
657 wimlib now preserves WIM integrity tables by default, even if
658 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
659 behavior of `wimlib-imagex' whenever the WIM being operated on contains
660 an integrity table and the '--check' option is not specified.
662 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
663 (when --compress is not specified). This provides the best compression
664 ratio by default, which is usually what is desired, at a cost of some
667 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
668 is the command as in `wimlib-imagex COMMAND'; for example, it can be
669 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
670 appropriate hard links are created in UNIX installations of
671 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
672 batch files that emulate this behavior are generated.
674 Security descriptors are now extracted correctly on Windows.
676 Fixed archiving DOS names in NTFS-3g capture mode.
678 The extraction code has been rewritten and it will now be easier to
679 support new features on all supported backends (currently Win32, UNIX,
680 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
681 now supported on all backends, not just UNIX.
683 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
684 than the WAIK itself.
686 wimlib_global_init() now, by default, attempts to acquire additional
687 privileges on Windows, so library clients need not do this.
689 This update bumps the shared library version number up to 9, since it is
690 not binary compatibible with previous releases.
693 Fixed bug in `wimlib-imagex export' that made it impossible to export an
694 image from a WIM that is readonly at the filesystem level.
696 Return error code rather than segfaulting when trying to list files from
697 a non-first part of a split WIM.
699 Joining a WIM will now preserve the RP_FIX and READONLY flags.
702 On Windows, paths given to wimlib-imagex are now treated case
705 Improved behavior regarding invalid filenames; in particular, on
706 Windows, wimlib-imagex will, when extracting, now omit (with an option
707 to override this default) filenames differing only in case, or filenames
708 containing characters not valid on Windows.
710 On Windows, wimlib now supports capturing and extracting long paths
711 (longer than the so-called MAX_PATH).
713 On Windows, `wimlib-imagex update' now acquires proper privileges when
714 running as an Administrator.
716 `wimlib-imagex update' will now complain if no image is specified when
717 trying to update a multi-image WIM.
719 `wimlib-imagex update' now supports specifying a single update command
720 directly on the command line using the --command option.
722 wimlib-imagex will now choose different units for progress messages,
723 depending on the amount of data that needs to be processed.
725 `wimlib-imagex append' will now generate a unique WIM image name if no
726 name is specified and the defaulted name already exists in the WIM.
728 wimlib now allows you to create unnamed WIM images, which can then only
729 be referred to by index.
731 wimlib now allows you to explicitly declare you want write access to a
732 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
735 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
738 Progress callbacks have been added to wimlib's wimlib_update_image()
741 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
742 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
745 NTFS-3g capture now only warns about two conditions previously treated
748 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
751 wimlib now correctly detects and returns an error when reading a WIM
752 image with a cyclic directory structure. (Fun fact: such a WIM will
753 crash Microsoft's software.)
756 Added new "extract" and "update" subcommands to wimlib-imagex, along
757 with associated APIs in the library. These commands are intended mainly
758 for Windows use but can be used on UNIX as well.
760 Many documentation improvements.
762 Fixed a bug in the Windows build where relative symbolic links were not
763 captured in reparse-point fixup mode.
765 Fixed a bug in the Windows build where file handles were left open to
766 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
768 Fixed a bug in the Windows build of wimlib-imagex where globbing
769 split-WIM parts could cause the program to crash.
771 Fixed a bug where the creation time of WIM images would be shown instead
772 of the last modification time.
774 With the Windows build it is now possible to restore a WIM containing
775 symbolic links as a non-Administrator; however you will receive warnings
776 about not being able to extract the symbolic links.
779 Capturing a WIM image should now be significantly faster in most cases
780 due to improved use of the operating system's cache and avoiding reading
781 files twice whenever possible.
783 The Windows build should now work on Windows XP.
785 The Windows build now supports capturing and restoring hidden,
786 compressed, sparse, and encrypted files.
788 The Windows build now supports capturing and applying WIM images from
789 filesystems other than NTFS (with some reduced functionality).
791 The Windows build now extracts short names correctly.
793 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
794 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
795 capture' and `wimlib-imagex apply'.
797 The performance of splitting and joining WIMs should be slightly
800 The LZX and XPRESS compression and decompression functions are now
801 exported from the library.
804 Improvements and bugfixes for the Windows build.
806 Added --strict-acls options.
808 Fixed the way that wimlib determines the order of images in the WIM.
811 Since wimlib can now be used on Windows, wimlib's implementation of
812 ImageX has been renamed to wimlib-imagex to avoid confusion with
813 Microsoft's implementation of ImageX, which would have the same file
814 name ("imagex.exe"). If you really don't like this you can pass the
815 --with-imagex-progname option to `configure' to choose a different name,
816 or even simply rename the binary yourself (but the former way will
817 configure the man pages to use the chosen name).
819 Various bugs fixed in the Windows build. Mainly to do with capturing
820 and restoring alternate data streams correctly in weird cases, and
821 requesting the correct privileges when opening files. Also added the
822 --noacls options to wimlib-imagex capture, append, and apply.
824 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
825 dynamically loaded, so this may make the library compatible with Windows
826 XP (however, there may still be other problems).
829 Added experimental support for native Windows builds. Binaries can be
830 downloaded from the SourceForge page.
832 --source-list option added to `imagex capture' and `imagex append'.
834 Better support for different character encodings.
837 Storing UNIX file owners, groups, and modes in WIM images is now
838 possible using `imagex capture' with the --unix-data flag.
840 Minor bug fixes and documentation fixes.
843 NTFS capture: Fixed capturing duplicate reparse points.
845 NTFS capture: Capture first unnamed stream if there are more than one
846 (print warning instead of error).
848 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
851 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
854 Update to work with ntfs-3g version 2013.1.13.
857 Fixed truncating file to shorter but non-zero length on read-write
860 Various code cleanups and minor documentation fixes.
863 LZX and XPRESS decompression have received some additional optimizations
864 and should now be even faster. (Although, they were already pretty
865 fast--- much faster than typical I/O speeds.)
867 Fixed a bug introduced in v1.2.1 that would cause a directory tree
868 containing hard links to be captured incorrectly in some cases.
871 By default, unmounting a read-write mounted WIM with 'imagex unmount
872 --commit' will now change the WIM in-place without needing to write the
873 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
876 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
877 for a response from the daemon servicing the mounted WIM. Instead,
878 every second 'imagex unmount' will check if the daemon is still alive,
879 and keep waiting if so, otherwise terminate with an error.
881 'imagex unmount --commit' on a read-write mounted WIM will now print
882 progress information regarding the writing of new or modified streams
883 the WIM, just like when capturing or appending a WIM.
885 A small change has been made to XPRESS compression and it should improve
886 the compression ratio slightly.
888 A change was made that may improve performance slightly when applying a
889 WIM image to a NTFS volume.
891 Microsoft has managed to introduce even more bugs into their software,
892 and now the WIMs for Windows 8 have incorrect (too low) reference counts
893 for some streams. This is unsafe because such streams can be removed
894 when they are in actuality still referenced in the WIM (perhaps by a
895 different image). wimlib will now work around this problem by fixing
896 the stream reference counts. This is only done when wimlib_delete_image() is
897 called ('imagex delete') or when wimlib_mount_image() is called with
898 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
899 requires reading the metadata for all images in the WIM, so this will
900 make these operations noticably slower on WIMs with multiple images.
902 Various other bugfixes.
905 Appending images to a WIM is now be done by default without re-building
906 the whole WIM. Use the --rebuild flag to get the old behavior (which
907 was to re-build the entire WIM when a new image is appended).
909 A new command `imagex optimize' is now available to manually re-build a
910 WIM that has wasted space due to repeated appends.
912 Progress information has been improved, and now arbitrary callback
913 functions can be used to show the progress of a WIM operation.
915 A possible bug with changing the bootable image of a WIM was fixed.
917 Some advisory locking is now done to prevent two processes from
918 modifying a WIM at the same time (but only in some cases). For example,
919 you cannot mount two images from a WIM read-write at the same time.
921 Some functions have been reorganized:
922 * wimlib_mount() renamed to wimlib_mount_image().
923 * wimlib_unmount() renamed to wimlib_unmount_image().
924 * wimlib_overwrite_xml_and_header() removed as
925 wimlib_overwrite() suffices now.
926 * wimlib_apply_image_to_ntfs_volume() removed as
927 wimlib_extract_image() suffices now.
928 * wimlib_add_image_from_ntfs_volume() removed as
929 * wimlib_add_image() suffices now.
931 Previously, the soname of libwim.so has been 0.0.0, despite many
932 interface changes. The soname is now updated to 1.0.0 and will now be
933 updated each release.
936 Resources will now be compressed using multiple threads by default.
937 (This applies to `imagex capture', `imagex append', and `imagex
940 Some performance improvements in mounted WIMs.
942 More progress information is shown when capturing a WIM.
945 Lots of minor fixes, code cleanups, and some documentation updates.
946 Nothing in particular is really noteworthy.
949 LZX and XPRESS compression improvements.
951 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
952 Link Bytes of the WIM.
955 Fixed bug when capturing NTFS file with multiple named data streams.
957 Internally, we are now using inode structures, even though these don't
958 appear literally in the WIM file. This simplifies some of the code
959 (mainly for WIM mounting) and likely fixed a few problems, although it
963 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
967 Enough changes to call it version 1.0.0!
969 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
970 to a NTFS volume, is now supported.
972 Hard links and symbolic links have much improved support. They are
973 supported for WIM capture, WIM application, and mounted WIMs (you can
974 even make them on read-write mounted WIMs).
976 Alternate data streams are now supported on mounted WIMs through an
977 xattr or a Windows-style stream interface. Also they are supported when
978 capturing a WIM from NTFS or applying a WIM to NTFS.
980 Split WIMs are better supported. You may now apply an image directly
981 from a split WIM, mount an image from a split WIM read-only, or export
982 an image from a split WIM.
984 Using a capture configuration file is now supported (but not fully yet).
986 SHA1 message digests are checked in more places, so we can make sure
987 applied and captured data is correct.
989 Man pages have been updated and consolidated.
992 Fixed segfault when unmounting read-only WIM.
995 Support for joining and splitting WIMs.
996 Also, security data is now preserved by default.
999 Can now build with older gcc and system headers, like on CentOS 5.
1002 Fixed bug that made it impossible to overwrite files in read-write
1006 Write byte-order mark before WIM XML data. (imagex.exe requires this to
