2 The LZX compression ratio has been slightly improved. The default mode,
3 LZX level 50, is now almost as good as the old LZX level 100, while
4 being nearly the same speed as before.
6 Decompression performance has been slightly improved.
8 Filenames are now always listed in NTFS collation order.
10 On UNIX-like systems, wimlib can now process Windows filenames that are
11 not valid Unicode due to the presence of unpaired surrogates.
13 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
14 addition of surrogate codepoints. Consequently, the environmental
15 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
16 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
18 wimlib no longer depends on iconv.
20 Reduced memory usage slightly.
22 When a WIM image is applied in NTFS-3G mode, security descriptors are
23 now created in NTFS v3.0 format when supported by the volume.
25 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
26 been removed. Users are advised to upgrade to a later version of
29 On Windows, wimlib now supports case-sensitive filename extraction when
30 supported by the underlying operating system and filesystem (operating
31 system support requires a registry setting).
34 On UNIX, wimlib can now overwrite readonly files when extracting.
36 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
37 NTFS permissions") set on some existing directories after extraction.
39 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
40 driver is not loaded, wimlib can now correctly register a new WIM file
41 with the target volume when the target volume previously had had WIM
44 Added a new testing program.
46 Clarified the main license text and updated public domain dedications
47 for certain files to be more thorough.
50 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
52 Reduced memory usage when exporting large numbers of WIM images.
54 Non UTF-8 locales are now detected correctly.
56 Addressed compiler warnings and enabled "silent" make rules by default.
58 Windows-specific updates:
59 Fixed a bug where duplicate backslashes could be generated in
60 link targets when extracting symbolic links and junctions.
62 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
63 work if their full path contained a space.
65 Fixed bugs related to scanning SMB filesystems.
67 Added warning message about known issue with WindowsApps folder.
69 Added instructions for building from source on Windows.
71 VSS support is no longer marked "experimental".
73 Added missing license file for libdivsufsort-lite.
76 Added experimental support for Windows VSS (Volume Shadow Copy Service).
77 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
78 create and use a temporary VSS snapshot when capturing a WIM image.
80 Implemented setting of Windows-specific XML information, such as
81 architecture, system root, and version details. This information is now
82 automatically set in newly captured WIM images, when appropriate.
84 Improved performance of directory tree scans on Windows.
86 On Windows, to improve capture performance, wimlib now sometimes opens
87 files by inode number rather than by path. This is enabled for
88 wimcapture and wimappend, but for now other applications have to opt-in.
90 The progress messages printed by wimlib-imagex while writing WIM files
91 have been slightly tweaked.
93 Progress information for directory tree scans now counts all hard links.
94 Also, on Windows "\\?\" is no longer stripped from the current path.
96 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
97 'wiminfo'. This option lets you assign values to elements in a WIM
98 file's XML document by name.
100 The wimlib_get_image_property() and wimlib_set_image_property() API
101 functions now support numerically indexed elements.
103 Fixed a bug where, on Windows, wimlib would change the security
104 descriptor of the target directory of an extraction even when the
105 '--no-acls' option was specified.
108 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
109 some Microsoft software would not correctly recognize data in the
110 resulting filesystem.
112 Made some small improvements to the compression algorithms:
113 LZX compression ratio was slightly improved.
114 XPRESS compression ratio and speed was slightly improved.
115 LZMS compression speed was slightly improved.
117 Improved handling of WIM XML data. wimlib no longer drops unrecognized
118 elements when exporting images. In addition, two API functions were
119 added for better access to elements in the XML document:
120 wimlib_get_image_property() and wimlib_set_image_property().
122 Added support for (unsafe) in-place compaction of WIM files.
124 Improved performance of image export by reusing metadata resources
125 instead of always rebuilding and recompressing them.
127 Improved performance of wimlib_update_image() by delaying the update to
128 the WIM's XML document until a write is requested.
130 On Windows, the target of an extraction may now be a reparse point
131 (which will be dereferenced).
133 On Windows, wimlib now correctly restores non-Microsoft reparse points.
134 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
136 On Windows, wimlib now has improved performance when archiving files
137 from a filesystem backed by a WIM (a "WIMBoot" setup).
139 Several improvements to System Compression (compact mode) support:
141 wof.sys (or wofadk.sys) is now automatically attached to the
142 target volume if needed.
144 Compact-mode extractions now work correctly with wofadk.sys on
145 older versions of Windows.
147 For compatibility with the Windows bootloader, the requested
148 compression format now is overridden on certain files.
150 Other minor bugfixes.
153 This release primarily contains various minor bug fixes and
154 improvements, including:
156 Improved handling of deep directory structures.
158 Fixed a bug where on 32-bit systems, the library could enter an
159 infinite loop if a WIM file was malformed in a specific way.
161 Added a workaround for a case where libntfs-3g may report
162 duplicate streams in an NTFS file.
164 Windows symbolic links and junctions in mounted WIM images are
165 now automatically rewritten to be valid in the mounted location.
167 Reparse point fixes: correctly handle the "ReparseReserved"
168 field, and correctly handle "empty" (data-less) reparse points.
170 On Windows, wimlib now acquires SeManageVolumePrivilege, which
171 is needed to create externally backed files using the
174 Improved validation of filenames.
176 Improved LZMS decompression speed.
178 The configure script now honors alternate pkg-config settings.
180 Links have been updated to point to the new website.
182 In addition, experimental support has been added for compressing
183 extracted files using System Compression on Windows 10. This
184 functionality is available through the new '--compact' option to
185 'wimapply' and 'wimextract' as well as new library flags.
188 Fixed a bug in the LZX decompressor: malicious input data could cause
189 out of bounds writes to memory (since wimlib v1.2.2).
191 The output of the 'wiminfo' command now consolidates various boolean
192 flags (such as "Relative path junction") into a single line.
194 A file can now have both an unnamed data stream ("file contents") and a
195 reparse point stream. Such files can exist as a result of the use of
196 certain Windows features, such as offline storage, including "OneDrive".
197 wimlib will now store and restore both streams on Windows as well as in
198 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
200 On Windows, named data streams of encrypted files are no longer stored
201 twice in WIM archives.
203 On Windows, named data streams are now correctly extracted to existing
204 "readonly" directories. Before, an error would be reported.
206 On Windows, it is now possible to do a "WIMBoot mode" extraction with
207 non-standalone WIMs such as delta WIMs.
209 On Windows, when doing an extraction in "WIMBoot mode", files larger
210 than 4 gigabytes are now never extracted as externally backed. This
211 works around a bug in Microsoft's "WOF" driver.
213 The '--enable-verify-compression' configure option has been removed. If
214 you want to verify a WIM file, use the 'wimverify' program.
216 The way the "file count", "directory count", "total bytes", and "hard
217 link bytes" image statistics (stored in the WIM XML data) is calculated
218 has been slightly changed.
220 In mounted WIM images, the disk usage provided for each file (st_blocks)
221 is now the compressed size rather than the uncompressed size.
223 The performance of the NTFS-3g and Windows capture modes has been
226 On UNIX-like systems, symbolic links whose targets contain the backslash
227 character are now handled correctly (losslessly).
230 Improved the LZX compressor. It is now 15-20% faster than before and
231 provides a slightly better compression ratio.
233 Improved the LZMS compressor. It now provides a compression ratio
234 slightly better than WIMGAPI while still being faster and using slightly
237 The compression chunk size in solid resources, e.g. when capturing or
238 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
239 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
240 better compression ratio and is the same value that WIMGAPI uses. The
241 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
242 lower than WIMGAPI's memory usage, but if it is too much, it is still
243 possible to choose a lower value, e.g. with the '--solid-chunk-size'
244 option to wimlib-imagex.
246 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
247 accept the 'K', 'M', and 'G' suffixes.
249 Files are now sorted by name extension when creating a solid WIM file.
251 Fixed various issues related to capture/apply of EFS-encrypted files on
254 The file list printed by 'wimdir' is now sorted by the platform-specific
255 case sensitivity setting, rather than always case sensitively. This
256 also affects the library function wimlib_iterate_dir_tree().
258 On Windows, some error and warning messages have been improved.
261 The Windows binary distribution no longer contains third party DLLs.
262 These dependencies are instead compiled directly into the libwim DLL.
264 Added more fixes for wimlib on non-x86 architectures such as ARM.
266 Extracting files to a Windows PE in-memory filesystem no longer fails if
267 the target files do not yet exist.
269 Improved the performance of XPRESS compression and LZMS decompression.
271 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
272 It will automatically be faster on newer Intel and AMD processors.
274 Removed the --with-imagex-progname and --enable-more-assertions
278 Fix for very slow export from solid WIM / ESD files.
280 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
282 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
283 may use this to treat some types of errors as non-fatal.
285 The library now permits making in-memory changes to a WIMStruct backed
286 by a read-only WIM file.
288 Fixes for "WIMBoot" extraction mode (Windows only):
290 When not using the WOF driver, extraction no longer fails if the
291 disk containing the WIM file has too many partitions.
293 When matching patterns in [PrepopulateList], all hard links of
294 each file are now considered.
296 The system registry files are now automatically treated as being
297 in [PrepopulateList].
299 Added a hack to try to work around an intermittent bug in
300 Microsoft's WOF (Windows Overlay Filesystem) driver.
303 Made more improvements to the XPRESS, LZX, and LZMS compressors.
305 A number of improvements to the Windows port:
307 Fixes for setting short filenames.
309 Faster "WIMBoot" extraction.
311 Updated and slimmed down the dependent DLLs.
313 ACL inheritence bits are now restored.
315 Mandatory integrity labels are now backed up and restored.
317 Added a workaround for an issue where in rare cases, wimlib could create
318 a compressed data stream that could not be read correctly by Windows
319 after an extraction in "WIMBoot" mode.
322 Added file count progress data for
323 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
324 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
326 Added support for testing file exclusions via the user-provided
329 Some documentation improvements.
331 Made some clarifications to the license text in the COPYING file.
334 Made more improvements to the XPRESS, LZX, and LZMS compressors.
336 The default compression mode for wimcapture is now LZX compression in
337 its default mode, which is the same as '--compress=maximum'.
339 You can now specify an optional integer compression level to the
340 '--compress' option; e.g. '--compress=lzx:75'.
342 Made a minor change to the LZMS compressor and decompressor to fix an
343 incompatibility with the Microsoft implementation. In the unlikely
344 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
345 earlier and a checksum error is reported when extracting files from it
346 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
349 Added 'verify' subcommand to wimlib-imagex.
351 Notable library changes:
353 Custom compressor parameters have been removed from the library
354 in favor of the simpler level-based API.
356 Decompressor parameters have been removed entirely.
358 Library users can now specify a custom file for warning and
359 error messages to be sent to, rather than the default of
362 New progress messages:
363 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
364 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
366 New function: wimlib_verify_wim().
369 Improved compression, decompression, and extraction performance.
371 Improved compatibility with version 3584 WIM / ESD files:
372 - Add support for reading and writing multiple solid blocks per
373 archive, which WIMGAPI/DISM can create when appending an image.
374 - Correctly create solid blocks larger than 4 GiB.
376 'add' commands passed to wimupdate will now replace existing
377 nondirectory files by default. Use the --no-replace option to get the
380 The license for the library now contains an exception that allows using
381 it under the LGPL. See the COPYING file for details.
383 In reparse-point fixup mode (the default for capture), symbolic links
384 and junctions that point outside the tree being captured are no longer
385 excluded from capture.
387 Added support for "WIMBoot" capture and extraction. See the
388 documentation for the new '--wimboot' option to wimcapture and wimapply
389 for more information.
391 On UNIX-like systems, you can now backup and restore device nodes, named
392 pipes, and sockets. In addition, 32-bit user and group IDs are now
395 The way that UNIX data is stored in WIM files has been changed. If you
396 captured any WIMs with the --unix-data option, to upgrade them you'll
397 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
398 re-capture them with --unix-data using this version.
400 wimlib now understands tagged metadata items, such as object IDs, that
401 can be stored in WIM directory entries.
403 Removed the --hardlink and --symlink options to wimapply, since I don't
404 think they are too useful and they got in the way of improving the code.
406 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
408 The 'mkwinpeimg' script now supports writing the ISO image to standard
411 The <ARCH> element in WIM XML data is now exported correctly.
413 On Windows, sparse file attributes are no longer set on extracted files.
414 Oddly enough, this actually saves disk space in some cases.
416 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
417 supported. Mounting WIM images now always requires extended attribute
418 support. Use --without-fuse to disable support for mounting WIM images;
419 this will also disable the need for extended attribute support.
421 Configuring with --enable-ssse3-sha1 now works correctly.
423 The shared library version has been bumped up. The main
424 incompatibilities are:
426 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
427 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
430 - User-provided progress functions are now registered using a
431 separate function, wimlib_register_progress_function(). The
432 'progress_func' argument to many functions no longer exists.
434 - The return value from user-provided progress functions is now
437 - A context argument has been added to the prototype of
438 user-provided progress functions.
440 - 'struct wimlib_capture_config' has been removed. The library
441 now takes the path to the configuration file directly. This
442 affects wimlib_add_image(), wimlib_add_image_multisource(),
443 and wimlib_update_image(). However, a NULL value passed in
444 the argument retains the same meaning.
446 - Removed deprecated functions: some (de)compression functions,
447 wimlib_extract_files(), and wimlib_print_metadata().
449 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
450 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
451 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
453 - Removed some progress messages:
454 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
455 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
456 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
459 - Removed some error codes. Numbering stays the same.
461 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
462 WIMLIB_UNMOUNT_FLAG_FORCE.
464 - WIM paths passed to progress functions now have a leading
468 Case-insensitive comparisons of strings (e.g. filenames) containing
469 UTF-16 codepoints above 32767 are now done correctly.
471 Fixed build failure on Mac OS X.
473 wimunmount now provides the '--new-image' option to cause changes to a
474 read-write mounted image to be committed as a new image rather than as
475 an update of the mounted image. (The corresponding new library flag is
476 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
478 The LZMS ("recovery") compression chunk size, or "dictionary size", may
479 now be up to 1 GiB (1,073,741,824 bytes).
481 The performance of LZX ("maximum") and LZMS ("recovery") compression
482 with large chunk sizes has been slightly improved.
485 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
486 decompressed correctly.
488 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
489 occurred in an unlikely case, and due to validity checks it did not
490 affect successfully created archives.
492 Fixed a minor compatibility issue with the LZMS compressor and
493 decompressor. This is *not* the default compression type and was only
494 introduced in v1.6.0. In the unlikely event that you created an
495 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
496 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
499 Memory usage for LZMS and LZX compression has been decreased.
501 wimextract now allows wildcard characters in paths specified on the
502 command line. Also, the '--strict-wildcards' option has been removed
503 and replaced with the inverse option '--nullglob'. See the
504 documentation for wimextract for more details and changes.
506 The wimlib_extract_files() function is now considered deprecated in
507 favor of wimlib_extract_paths().
509 Fixed more permissions problems when extracting files on Windows.
511 A new '--no-attributes' option has been added to wimapply and
512 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
514 The default chunk size is now set correctly when changing the
515 compression type of a WIM, for example with 'wimoptimize'.
517 The '--metadata' option to wiminfo has been replaced with the
518 '--detailed' option to wimdir.
520 In relevant wimlib-imagex commands, '--solid' may now be used as an
521 alias for '--pack-streams'.
524 Support for extracting and updating the new version 3584 WIMs has been
525 added. These WIMs typically pack many streams ("files") together into a
526 single compressed resource, thereby saving space. This degrades the
527 performance of random access (such as that which occurs on a mounted
528 image), but optimizations have been implemented for extraction. These
529 new WIM files also typically use a new compression format (LZMS), which
530 is similar to LZMA and can offer a better compression ratio than LZX.
531 These new WIM files can be created using `wimcapture' with
532 the '--compress=lzms --pack-streams' options. Note: this new WIM format
533 is used by the Windows 8 web downloader, but important segments of the
534 raw '.esd' files are encrypted, so wimlib will not be able to extract
535 such files until they are first decrypted.
537 wimlib now supports extracting files and directories from a WIM image
538 based on a "listfile" that itself contains the list of paths to extract.
539 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
540 and for the library itself, the new APIs are wimlib_extract_pathlist()
541 and wimlib_extract_paths(). Path globs containing wildcard characters
544 For searching WIM files, wimlib now has configurable case sensitivity.
545 The default on Windows is still case-insensitive and the default on
546 UNIX-like systems is still case-sensitive, but this can be overridden
547 on either platform through flags to wimlib_global_init(). For
548 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
549 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
552 Support for compression chunk sizes greater than the default of 32768
553 bytes has been added. A larger chunk size typically results in a better
554 compression ratio. However, the MS implementation is seemingly not
555 compatible with all chunk sizes, especially for LZX compression, so the
556 defaults remain unchanged, with the exception of the new LZMS-compressed
557 WIMs, which use a larger chunk size by default.
559 The compression/decompression API exported by wimlib has been changed.
560 Now one set of functions handles all supported compression formats.
562 `wimcapture' and `wimappend' will now display the progress of scanning
563 the directory tree to capture, in addition to the progress of writing
564 data to the WIM. The '--verbose' option no longer does anything. The
565 library API change for this is the addition of several members to
566 `struct wimlib_progress_info_scan' available to progress callbacks.
568 `mkwinpeimg' now correctly handles the '--start-script' option when the
569 start script is not in the working directory.
571 Sequential extraction, previously requested by using
572 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
573 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
574 behavior (extract in file order).
577 The new LZX compressor added in v1.5.2 has been improved and is now
578 enabled by default, except when `wimcapture' or `wimappend' is run
579 *without* the '--compress' option, in which case the faster LZX
580 compressor is used (the same as before). This behavior is reasonably
581 consistent with ImageX which actually uses "fast" (XPRESS) compression
582 by default. In those cases, use '--compress=maximum' to explicitly
583 capture a WIM image using the new (slower but better) LZX compressor.
585 The '--compress-slow' option still exists to `wimlib-imagex optimize',
586 but its new behavior is to tweak the new LZX compressor even more to
587 produce an even better compression ratio at the cost of more time spent
590 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
591 which recompresses the WIM file using the specified compression TYPE.
592 The new library API function used for this is
593 wimlib_set_output_compression_type().
595 Added the wimlib_get_xml_data() function to allow library clients to
596 easily retrieve the raw XML data from a WIM file if needed.
598 Fixed a bug that could cause an error code to be incorrectly returned
599 when writing XML data containing a <WINDOWS> element.
601 Mounted WIM images will now correctly show the default file stream even
602 if appears in the alternate data stream entries of the corresponding WIM
606 Added a new experimental LZX compressor which can be enabled by passing
607 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
608 optimize'. (The latter is only applicable if the WIM is already
609 LZX-compressed and the '--recompress' option is also given.) The
610 experimental compressor is much slower but compresses the data slightly
611 more --- currently usually to within a fraction of a percent of the
612 results from WIMGAPI/ImageX.
614 A workaround has been added for compatibility with versions of WinPE
615 that interpret alternate data stream entries in the boot WIM
618 An alignment bug that caused a crash in the LZX decompressor on some
621 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
622 the WIM header when restoring the previous state of a WIM it failed to
625 Added a workaround to avoid an access denied error on Windows when
626 replacing a WIM file that another process has opened.
629 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
630 needed to be handled.
632 A bug in the interpretation of negative IMAGE indices in the
633 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
634 `wimlib-imagex append' has been fixed.
636 A workaround has been added to successfully apply security descriptors
637 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
638 2013.1.13 or earlier.
640 `wimlib-imagex capture' can now accept the '--delta-from' option
644 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
645 to standard output and applying images from standard input, but they are
646 not compatible with Microsoft's software and are not created by default.
647 See the documentation for --pipable flag of `wimlib-imagex capture' for
650 To better support incremental backups, added support for declaring an
651 image as a modified form of another image. See the documentation for
652 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
655 Added supported for "delta" WIMs. See the documentation for the
656 '--delta-from' option of `wimlib-imagex capture'.
658 The library support for managing split WIMs has been changed to support
659 other arrangements, such as delta WIMs, and be easier to use. This
660 change is visible in `wimlib-imagex', which also can now accept the
661 '--ref' option multiple times, and also now supports "delta" WIMs as
664 wimlib now preserves WIM integrity tables by default, even if
665 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
666 behavior of `wimlib-imagex' whenever the WIM being operated on contains
667 an integrity table and the '--check' option is not specified.
669 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
670 (when --compress is not specified). This provides the best compression
671 ratio by default, which is usually what is desired, at a cost of some
674 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
675 is the command as in `wimlib-imagex COMMAND'; for example, it can be
676 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
677 appropriate hard links are created in UNIX installations of
678 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
679 batch files that emulate this behavior are generated.
681 Security descriptors are now extracted correctly on Windows.
683 Fixed archiving DOS names in NTFS-3g capture mode.
685 The extraction code has been rewritten and it will now be easier to
686 support new features on all supported backends (currently Win32, UNIX,
687 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
688 now supported on all backends, not just UNIX.
690 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
691 than the WAIK itself.
693 wimlib_global_init() now, by default, attempts to acquire additional
694 privileges on Windows, so library clients need not do this.
696 This update bumps the shared library version number up to 9, since it is
697 not binary compatibible with previous releases.
700 Fixed bug in `wimlib-imagex export' that made it impossible to export an
701 image from a WIM that is readonly at the filesystem level.
703 Return error code rather than segfaulting when trying to list files from
704 a non-first part of a split WIM.
706 Joining a WIM will now preserve the RP_FIX and READONLY flags.
709 On Windows, paths given to wimlib-imagex are now treated case
712 Improved behavior regarding invalid filenames; in particular, on
713 Windows, wimlib-imagex will, when extracting, now omit (with an option
714 to override this default) filenames differing only in case, or filenames
715 containing characters not valid on Windows.
717 On Windows, wimlib now supports capturing and extracting long paths
718 (longer than the so-called MAX_PATH).
720 On Windows, `wimlib-imagex update' now acquires proper privileges when
721 running as an Administrator.
723 `wimlib-imagex update' will now complain if no image is specified when
724 trying to update a multi-image WIM.
726 `wimlib-imagex update' now supports specifying a single update command
727 directly on the command line using the --command option.
729 wimlib-imagex will now choose different units for progress messages,
730 depending on the amount of data that needs to be processed.
732 `wimlib-imagex append' will now generate a unique WIM image name if no
733 name is specified and the defaulted name already exists in the WIM.
735 wimlib now allows you to create unnamed WIM images, which can then only
736 be referred to by index.
738 wimlib now allows you to explicitly declare you want write access to a
739 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
742 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
745 Progress callbacks have been added to wimlib's wimlib_update_image()
748 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
749 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
752 NTFS-3g capture now only warns about two conditions previously treated
755 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
758 wimlib now correctly detects and returns an error when reading a WIM
759 image with a cyclic directory structure. (Fun fact: such a WIM will
760 crash Microsoft's software.)
763 Added new "extract" and "update" subcommands to wimlib-imagex, along
764 with associated APIs in the library. These commands are intended mainly
765 for Windows use but can be used on UNIX as well.
767 Many documentation improvements.
769 Fixed a bug in the Windows build where relative symbolic links were not
770 captured in reparse-point fixup mode.
772 Fixed a bug in the Windows build where file handles were left open to
773 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
775 Fixed a bug in the Windows build of wimlib-imagex where globbing
776 split-WIM parts could cause the program to crash.
778 Fixed a bug where the creation time of WIM images would be shown instead
779 of the last modification time.
781 With the Windows build it is now possible to restore a WIM containing
782 symbolic links as a non-Administrator; however you will receive warnings
783 about not being able to extract the symbolic links.
786 Capturing a WIM image should now be significantly faster in most cases
787 due to improved use of the operating system's cache and avoiding reading
788 files twice whenever possible.
790 The Windows build should now work on Windows XP.
792 The Windows build now supports capturing and restoring hidden,
793 compressed, sparse, and encrypted files.
795 The Windows build now supports capturing and applying WIM images from
796 filesystems other than NTFS (with some reduced functionality).
798 The Windows build now extracts short names correctly.
800 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
801 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
802 capture' and `wimlib-imagex apply'.
804 The performance of splitting and joining WIMs should be slightly
807 The LZX and XPRESS compression and decompression functions are now
808 exported from the library.
811 Improvements and bugfixes for the Windows build.
813 Added --strict-acls options.
815 Fixed the way that wimlib determines the order of images in the WIM.
818 Since wimlib can now be used on Windows, wimlib's implementation of
819 ImageX has been renamed to wimlib-imagex to avoid confusion with
820 Microsoft's implementation of ImageX, which would have the same file
821 name ("imagex.exe"). If you really don't like this you can pass the
822 --with-imagex-progname option to `configure' to choose a different name,
823 or even simply rename the binary yourself (but the former way will
824 configure the man pages to use the chosen name).
826 Various bugs fixed in the Windows build. Mainly to do with capturing
827 and restoring alternate data streams correctly in weird cases, and
828 requesting the correct privileges when opening files. Also added the
829 --noacls options to wimlib-imagex capture, append, and apply.
831 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
832 dynamically loaded, so this may make the library compatible with Windows
833 XP (however, there may still be other problems).
836 Added experimental support for native Windows builds. Binaries can be
837 downloaded from the SourceForge page.
839 --source-list option added to `imagex capture' and `imagex append'.
841 Better support for different character encodings.
844 Storing UNIX file owners, groups, and modes in WIM images is now
845 possible using `imagex capture' with the --unix-data flag.
847 Minor bug fixes and documentation fixes.
850 NTFS capture: Fixed capturing duplicate reparse points.
852 NTFS capture: Capture first unnamed stream if there are more than one
853 (print warning instead of error).
855 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
858 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
861 Update to work with ntfs-3g version 2013.1.13.
864 Fixed truncating file to shorter but non-zero length on read-write
867 Various code cleanups and minor documentation fixes.
870 LZX and XPRESS decompression have received some additional optimizations
871 and should now be even faster. (Although, they were already pretty
872 fast--- much faster than typical I/O speeds.)
874 Fixed a bug introduced in v1.2.1 that would cause a directory tree
875 containing hard links to be captured incorrectly in some cases.
878 By default, unmounting a read-write mounted WIM with 'imagex unmount
879 --commit' will now change the WIM in-place without needing to write the
880 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
883 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
884 for a response from the daemon servicing the mounted WIM. Instead,
885 every second 'imagex unmount' will check if the daemon is still alive,
886 and keep waiting if so, otherwise terminate with an error.
888 'imagex unmount --commit' on a read-write mounted WIM will now print
889 progress information regarding the writing of new or modified streams
890 the WIM, just like when capturing or appending a WIM.
892 A small change has been made to XPRESS compression and it should improve
893 the compression ratio slightly.
895 A change was made that may improve performance slightly when applying a
896 WIM image to a NTFS volume.
898 Microsoft has managed to introduce even more bugs into their software,
899 and now the WIMs for Windows 8 have incorrect (too low) reference counts
900 for some streams. This is unsafe because such streams can be removed
901 when they are in actuality still referenced in the WIM (perhaps by a
902 different image). wimlib will now work around this problem by fixing
903 the stream reference counts. This is only done when wimlib_delete_image() is
904 called ('imagex delete') or when wimlib_mount_image() is called with
905 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
906 requires reading the metadata for all images in the WIM, so this will
907 make these operations noticably slower on WIMs with multiple images.
909 Various other bugfixes.
912 Appending images to a WIM is now be done by default without re-building
913 the whole WIM. Use the --rebuild flag to get the old behavior (which
914 was to re-build the entire WIM when a new image is appended).
916 A new command `imagex optimize' is now available to manually re-build a
917 WIM that has wasted space due to repeated appends.
919 Progress information has been improved, and now arbitrary callback
920 functions can be used to show the progress of a WIM operation.
922 A possible bug with changing the bootable image of a WIM was fixed.
924 Some advisory locking is now done to prevent two processes from
925 modifying a WIM at the same time (but only in some cases). For example,
926 you cannot mount two images from a WIM read-write at the same time.
928 Some functions have been reorganized:
929 * wimlib_mount() renamed to wimlib_mount_image().
930 * wimlib_unmount() renamed to wimlib_unmount_image().
931 * wimlib_overwrite_xml_and_header() removed as
932 wimlib_overwrite() suffices now.
933 * wimlib_apply_image_to_ntfs_volume() removed as
934 wimlib_extract_image() suffices now.
935 * wimlib_add_image_from_ntfs_volume() removed as
936 * wimlib_add_image() suffices now.
938 Previously, the soname of libwim.so has been 0.0.0, despite many
939 interface changes. The soname is now updated to 1.0.0 and will now be
940 updated each release.
943 Resources will now be compressed using multiple threads by default.
944 (This applies to `imagex capture', `imagex append', and `imagex
947 Some performance improvements in mounted WIMs.
949 More progress information is shown when capturing a WIM.
952 Lots of minor fixes, code cleanups, and some documentation updates.
953 Nothing in particular is really noteworthy.
956 LZX and XPRESS compression improvements.
958 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
959 Link Bytes of the WIM.
962 Fixed bug when capturing NTFS file with multiple named data streams.
964 Internally, we are now using inode structures, even though these don't
965 appear literally in the WIM file. This simplifies some of the code
966 (mainly for WIM mounting) and likely fixed a few problems, although it
970 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
974 Enough changes to call it version 1.0.0!
976 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
977 to a NTFS volume, is now supported.
979 Hard links and symbolic links have much improved support. They are
980 supported for WIM capture, WIM application, and mounted WIMs (you can
981 even make them on read-write mounted WIMs).
983 Alternate data streams are now supported on mounted WIMs through an
984 xattr or a Windows-style stream interface. Also they are supported when
985 capturing a WIM from NTFS or applying a WIM to NTFS.
987 Split WIMs are better supported. You may now apply an image directly
988 from a split WIM, mount an image from a split WIM read-only, or export
989 an image from a split WIM.
991 Using a capture configuration file is now supported (but not fully yet).
993 SHA1 message digests are checked in more places, so we can make sure
994 applied and captured data is correct.
996 Man pages have been updated and consolidated.
999 Fixed segfault when unmounting read-only WIM.
1002 Support for joining and splitting WIMs.
1003 Also, security data is now preserved by default.
1006 Can now build with older gcc and system headers, like on CentOS 5.
1009 Fixed bug that made it impossible to overwrite files in read-write
1013 Write byte-order mark before WIM XML data. (imagex.exe requires this to
