2 Added support for object IDs, which are a type of metadata sometimes
3 present on NTFS filesystems. They are used by some Windows software,
4 such as the Distributed Link Tracking Service. Object IDs are now
5 captured and applied both in NTFS-3g mode and on Windows when supported
8 Reduced memory usage when exporting large numbers of WIM images.
10 Made some minor build-related updates. Notably, enabled "silent" make
11 rules; this makes the output cleaner when building from source.
13 Some Windows-specific updates:
14 Fixed a bug where duplicate backslashes could be generated in
15 link targets when extracting symbolic links and junctions.
17 Fixed a bug where the .cmd shortcuts for wimlib-imagex would not
18 work if their full path contained a space.
20 Fixed bugs when capturing a WIM image from a SMB filesystem.
22 Added warning message about known issue with WindowsApps folder.
24 Added instructions for building from source on Windows.
26 VSS support is no longer marked "experimental".
28 Added missing license file for libdivsufsort-lite.
31 Added experimental support for Windows VSS (Volume Shadow Copy Service).
32 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
33 create and use a temporary VSS snapshot when capturing a WIM image.
35 Implemented setting of Windows-specific XML information, such as
36 architecture, system root, and version details. This information is now
37 automatically set in newly captured WIM images, when appropriate.
39 Improved performance of directory tree scans on Windows.
41 On Windows, to improve capture performance, wimlib now sometimes opens
42 files by inode number rather than by path. This is enabled for
43 wimcapture and wimappend, but for now other applications have to opt-in.
45 The progress messages printed by wimlib-imagex while writing WIM files
46 have been slightly tweaked.
48 Progress information for directory tree scans now counts all hard links.
49 Also, on Windows "\\?\" is no longer stripped from the current path.
51 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
52 'wiminfo'. This option lets you assign values to elements in a WIM
53 file's XML document by name.
55 The wimlib_get_image_property() and wimlib_set_image_property() API
56 functions now support numerically indexed elements.
58 Fixed a bug where, on Windows, wimlib would change the security
59 descriptor of the target directory of an extraction even when the
60 '--no-acls' option was specified.
63 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
64 some Microsoft software would not correctly recognize data in the
67 Made some small improvements to the compression algorithms:
68 LZX compression ratio was slightly improved.
69 XPRESS compression ratio and speed was slightly improved.
70 LZMS compression speed was slightly improved.
72 Improved handling of WIM XML data. wimlib no longer drops unrecognized
73 elements when exporting images. In addition, two API functions were
74 added for better access to elements in the XML document:
75 wimlib_get_image_property() and wimlib_set_image_property().
77 Added support for (unsafe) in-place compaction of WIM files.
79 Improved performance of image export by reusing metadata resources
80 instead of always rebuilding and recompressing them.
82 Improved performance of wimlib_update_image() by delaying the update to
83 the WIM's XML document until a write is requested.
85 On Windows, the target of an extraction may now be a reparse point
86 (which will be dereferenced).
88 On Windows, wimlib now correctly restores non-Microsoft reparse points.
89 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
91 On Windows, wimlib now has improved performance when archiving files
92 from a filesystem backed by a WIM (a "WIMBoot" setup).
94 Several improvements to System Compression (compact mode) support:
96 wof.sys (or wofadk.sys) is now automatically attached to the
97 target volume if needed.
99 Compact-mode extractions now work correctly with wofadk.sys on
100 older versions of Windows.
102 For compatibility with the Windows bootloader, the requested
103 compression format now is overridden on certain files.
105 Other minor bugfixes.
108 This release primarily contains various minor bug fixes and
109 improvements, including:
111 Improved handling of deep directory structures.
113 Fixed a bug where on 32-bit systems, the library could enter an
114 infinite loop if a WIM file was malformed in a specific way.
116 Added a workaround for a case where libntfs-3g may report
117 duplicate streams in an NTFS file.
119 Windows symbolic links and junctions in mounted WIM images are
120 now automatically rewritten to be valid in the mounted location.
122 Reparse point fixes: correctly handle the "ReparseReserved"
123 field, and correctly handle "empty" (data-less) reparse points.
125 On Windows, wimlib now acquires SeManageVolumePrivilege, which
126 is needed to create externally backed files using the
129 Improved validation of filenames.
131 Improved LZMS decompression speed.
133 The configure script now honors alternate pkg-config settings.
135 Links have been updated to point to the new website.
137 In addition, experimental support has been added for compressing
138 extracted files using System Compression on Windows 10. This
139 functionality is available through the new '--compact' option to
140 'wimapply' and 'wimextract' as well as new library flags.
143 Fixed a bug in the LZX decompressor: malicious input data could cause
144 out of bounds writes to memory (since wimlib v1.2.2).
146 The output of the 'wiminfo' command now consolidates various boolean
147 flags (such as "Relative path junction") into a single line.
149 A file can now have both an unnamed data stream ("file contents") and a
150 reparse point stream. Such files can exist as a result of the use of
151 certain Windows features, such as offline storage, including "OneDrive".
152 wimlib will now store and restore both streams on Windows as well as in
153 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
155 On Windows, named data streams of encrypted files are no longer stored
156 twice in WIM archives.
158 On Windows, named data streams are now correctly extracted to existing
159 "readonly" directories. Before, an error would be reported.
161 On Windows, it is now possible to do a "WIMBoot mode" extraction with
162 non-standalone WIMs such as delta WIMs.
164 On Windows, when doing an extraction in "WIMBoot mode", files larger
165 than 4 gigabytes are now never extracted as externally backed. This
166 works around a bug in Microsoft's "WOF" driver.
168 The '--enable-verify-compression' configure option has been removed. If
169 you want to verify a WIM file, use the 'wimverify' program.
171 The way the "file count", "directory count", "total bytes", and "hard
172 link bytes" image statistics (stored in the WIM XML data) is calculated
173 has been slightly changed.
175 In mounted WIM images, the disk usage provided for each file (st_blocks)
176 is now the compressed size rather than the uncompressed size.
178 The performance of the NTFS-3g and Windows capture modes has been
181 On UNIX-like systems, symbolic links whose targets contain the backslash
182 character are now handled correctly (losslessly).
185 Improved the LZX compressor. It is now 15-20% faster than before and
186 provides a slightly better compression ratio.
188 Improved the LZMS compressor. It now provides a compression ratio
189 slightly better than WIMGAPI while still being faster and using slightly
192 The compression chunk size in solid resources, e.g. when capturing or
193 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
194 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
195 better compression ratio and is the same value that WIMGAPI uses. The
196 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
197 lower than WIMGAPI's memory usage, but if it is too much, it is still
198 possible to choose a lower value, e.g. with the '--solid-chunk-size'
199 option to wimlib-imagex.
201 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
202 accept the 'K', 'M', and 'G' suffixes.
204 Files are now sorted by name extension when creating a solid WIM file.
206 Fixed various issues related to capture/apply of EFS-encrypted files on
209 The file list printed by 'wimdir' is now sorted by the platform-specific
210 case sensitivity setting, rather than always case sensitively. This
211 also affects the library function wimlib_iterate_dir_tree().
213 On Windows, some error and warning messages have been improved.
216 The Windows binary distribution no longer contains third party DLLs.
217 These dependencies are instead compiled directly into the libwim DLL.
219 Added more fixes for wimlib on non-x86 architectures such as ARM.
221 Extracting files to a Windows PE in-memory filesystem no longer fails if
222 the target files do not yet exist.
224 Improved the performance of XPRESS compression and LZMS decompression.
226 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
227 It will automatically be faster on newer Intel and AMD processors.
229 Removed the --with-imagex-progname and --enable-more-assertions
233 Fix for very slow export from solid WIM / ESD files.
235 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
237 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
238 may use this to treat some types of errors as non-fatal.
240 The library now permits making in-memory changes to a WIMStruct backed
241 by a read-only WIM file.
243 Fixes for "WIMBoot" extraction mode (Windows only):
245 When not using the WOF driver, extraction no longer fails if the
246 disk containing the WIM file has too many partitions.
248 When matching patterns in [PrepopulateList], all hard links of
249 each file are now considered.
251 The system registry files are now automatically treated as being
252 in [PrepopulateList].
254 Added a hack to try to work around an intermittent bug in
255 Microsoft's WOF (Windows Overlay Filesystem) driver.
258 Made more improvements to the XPRESS, LZX, and LZMS compressors.
260 A number of improvements to the Windows port:
262 Fixes for setting short filenames.
264 Faster "WIMBoot" extraction.
266 Updated and slimmed down the dependent DLLs.
268 ACL inheritence bits are now restored.
270 Mandatory integrity labels are now backed up and restored.
272 Added a workaround for an issue where in rare cases, wimlib could create
273 a compressed data stream that could not be read correctly by Windows
274 after an extraction in "WIMBoot" mode.
277 Added file count progress data for
278 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
279 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
281 Added support for testing file exclusions via the user-provided
284 Some documentation improvements.
286 Made some clarifications to the license text in the COPYING file.
289 Made more improvements to the XPRESS, LZX, and LZMS compressors.
291 The default compression mode for wimcapture is now LZX compression in
292 its default mode, which is the same as '--compress=maximum'.
294 You can now specify an optional integer compression level to the
295 '--compress' option; e.g. '--compress=lzx:75'.
297 Made a minor change to the LZMS compressor and decompressor to fix an
298 incompatibility with the Microsoft implementation. In the unlikely
299 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
300 earlier and a checksum error is reported when extracting files from it
301 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
304 Added 'verify' subcommand to wimlib-imagex.
306 Notable library changes:
308 Custom compressor parameters have been removed from the library
309 in favor of the simpler level-based API.
311 Decompressor parameters have been removed entirely.
313 Library users can now specify a custom file for warning and
314 error messages to be sent to, rather than the default of
317 New progress messages:
318 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
319 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
321 New function: wimlib_verify_wim().
324 Improved compression, decompression, and extraction performance.
326 Improved compatibility with version 3584 WIM / ESD files:
327 - Add support for reading and writing multiple solid blocks per
328 archive, which WIMGAPI/DISM can create when appending an image.
329 - Correctly create solid blocks larger than 4 GiB.
331 'add' commands passed to wimupdate will now replace existing
332 nondirectory files by default. Use the --no-replace option to get the
335 The license for the library now contains an exception that allows using
336 it under the LGPL. See the COPYING file for details.
338 In reparse-point fixup mode (the default for capture), symbolic links
339 and junctions that point outside the tree being captured are no longer
340 excluded from capture.
342 Added support for "WIMBoot" capture and extraction. See the
343 documentation for the new '--wimboot' option to wimcapture and wimapply
344 for more information.
346 On UNIX-like systems, you can now backup and restore device nodes, named
347 pipes, and sockets. In addition, 32-bit user and group IDs are now
350 The way that UNIX data is stored in WIM files has been changed. If you
351 captured any WIMs with the --unix-data option, to upgrade them you'll
352 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
353 re-capture them with --unix-data using this version.
355 wimlib now understands tagged metadata items, such as object IDs, that
356 can be stored in WIM directory entries.
358 Removed the --hardlink and --symlink options to wimapply, since I don't
359 think they are too useful and they got in the way of improving the code.
361 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
363 The 'mkwinpeimg' script now supports writing the ISO image to standard
366 The <ARCH> element in WIM XML data is now exported correctly.
368 On Windows, sparse file attributes are no longer set on extracted files.
369 Oddly enough, this actually saves disk space in some cases.
371 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
372 supported. Mounting WIM images now always requires extended attribute
373 support. Use --without-fuse to disable support for mounting WIM images;
374 this will also disable the need for extended attribute support.
376 Configuring with --enable-ssse3-sha1 now works correctly.
378 The shared library version has been bumped up. The main
379 incompatibilities are:
381 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
382 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
385 - User-provided progress functions are now registered using a
386 separate function, wimlib_register_progress_function(). The
387 'progress_func' argument to many functions no longer exists.
389 - The return value from user-provided progress functions is now
392 - A context argument has been added to the prototype of
393 user-provided progress functions.
395 - 'struct wimlib_capture_config' has been removed. The library
396 now takes the path to the configuration file directly. This
397 affects wimlib_add_image(), wimlib_add_image_multisource(),
398 and wimlib_update_image(). However, a NULL value passed in
399 the argument retains the same meaning.
401 - Removed deprecated functions: some (de)compression functions,
402 wimlib_extract_files(), and wimlib_print_metadata().
404 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
405 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
406 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
408 - Removed some progress messages:
409 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
410 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
411 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
414 - Removed some error codes. Numbering stays the same.
416 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
417 WIMLIB_UNMOUNT_FLAG_FORCE.
419 - WIM paths passed to progress functions now have a leading
423 Case-insensitive comparisons of strings (e.g. filenames) containing
424 UTF-16 codepoints above 32767 are now done correctly.
426 Fixed build failure on Mac OS X.
428 wimunmount now provides the '--new-image' option to cause changes to a
429 read-write mounted image to be committed as a new image rather than as
430 an update of the mounted image. (The corresponding new library flag is
431 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
433 The LZMS ("recovery") compression chunk size, or "dictionary size", may
434 now be up to 1 GiB (1,073,741,824 bytes).
436 The performance of LZX ("maximum") and LZMS ("recovery") compression
437 with large chunk sizes has been slightly improved.
440 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
441 decompressed correctly.
443 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
444 occurred in an unlikely case, and due to validity checks it did not
445 affect successfully created archives.
447 Fixed a minor compatibility issue with the LZMS compressor and
448 decompressor. This is *not* the default compression type and was only
449 introduced in v1.6.0. In the unlikely event that you created an
450 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
451 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
454 Memory usage for LZMS and LZX compression has been decreased.
456 wimextract now allows wildcard characters in paths specified on the
457 command line. Also, the '--strict-wildcards' option has been removed
458 and replaced with the inverse option '--nullglob'. See the
459 documentation for wimextract for more details and changes.
461 The wimlib_extract_files() function is now considered deprecated in
462 favor of wimlib_extract_paths().
464 Fixed more permissions problems when extracting files on Windows.
466 A new '--no-attributes' option has been added to wimapply and
467 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
469 The default chunk size is now set correctly when changing the
470 compression type of a WIM, for example with 'wimoptimize'.
472 The '--metadata' option to wiminfo has been replaced with the
473 '--detailed' option to wimdir.
475 In relevant wimlib-imagex commands, '--solid' may now be used as an
476 alias for '--pack-streams'.
479 Support for extracting and updating the new version 3584 WIMs has been
480 added. These WIMs typically pack many streams ("files") together into a
481 single compressed resource, thereby saving space. This degrades the
482 performance of random access (such as that which occurs on a mounted
483 image), but optimizations have been implemented for extraction. These
484 new WIM files also typically use a new compression format (LZMS), which
485 is similar to LZMA and can offer a better compression ratio than LZX.
486 These new WIM files can be created using `wimcapture' with
487 the '--compress=lzms --pack-streams' options. Note: this new WIM format
488 is used by the Windows 8 web downloader, but important segments of the
489 raw '.esd' files are encrypted, so wimlib will not be able to extract
490 such files until they are first decrypted.
492 wimlib now supports extracting files and directories from a WIM image
493 based on a "listfile" that itself contains the list of paths to extract.
494 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
495 and for the library itself, the new APIs are wimlib_extract_pathlist()
496 and wimlib_extract_paths(). Path globs containing wildcard characters
499 For searching WIM files, wimlib now has configurable case sensitivity.
500 The default on Windows is still case-insensitive and the default on
501 UNIX-like systems is still case-sensitive, but this can be overridden
502 on either platform through flags to wimlib_global_init(). For
503 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
504 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
507 Support for compression chunk sizes greater than the default of 32768
508 bytes has been added. A larger chunk size typically results in a better
509 compression ratio. However, the MS implementation is seemingly not
510 compatible with all chunk sizes, especially for LZX compression, so the
511 defaults remain unchanged, with the exception of the new LZMS-compressed
512 WIMs, which use a larger chunk size by default.
514 The compression/decompression API exported by wimlib has been changed.
515 Now one set of functions handles all supported compression formats.
517 `wimcapture' and `wimappend' will now display the progress of scanning
518 the directory tree to capture, in addition to the progress of writing
519 data to the WIM. The '--verbose' option no longer does anything. The
520 library API change for this is the addition of several members to
521 `struct wimlib_progress_info_scan' available to progress callbacks.
523 `mkwinpeimg' now correctly handles the '--start-script' option when the
524 start script is not in the working directory.
526 Sequential extraction, previously requested by using
527 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
528 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
529 behavior (extract in file order).
532 The new LZX compressor added in v1.5.2 has been improved and is now
533 enabled by default, except when `wimcapture' or `wimappend' is run
534 *without* the '--compress' option, in which case the faster LZX
535 compressor is used (the same as before). This behavior is reasonably
536 consistent with ImageX which actually uses "fast" (XPRESS) compression
537 by default. In those cases, use '--compress=maximum' to explicitly
538 capture a WIM image using the new (slower but better) LZX compressor.
540 The '--compress-slow' option still exists to `wimlib-imagex optimize',
541 but its new behavior is to tweak the new LZX compressor even more to
542 produce an even better compression ratio at the cost of more time spent
545 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
546 which recompresses the WIM file using the specified compression TYPE.
547 The new library API function used for this is
548 wimlib_set_output_compression_type().
550 Added the wimlib_get_xml_data() function to allow library clients to
551 easily retrieve the raw XML data from a WIM file if needed.
553 Fixed a bug that could cause an error code to be incorrectly returned
554 when writing XML data containing a <WINDOWS> element.
556 Mounted WIM images will now correctly show the default file stream even
557 if appears in the alternate data stream entries of the corresponding WIM
561 Added a new experimental LZX compressor which can be enabled by passing
562 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
563 optimize'. (The latter is only applicable if the WIM is already
564 LZX-compressed and the '--recompress' option is also given.) The
565 experimental compressor is much slower but compresses the data slightly
566 more --- currently usually to within a fraction of a percent of the
567 results from WIMGAPI/ImageX.
569 A workaround has been added for compatibility with versions of WinPE
570 that interpret alternate data stream entries in the boot WIM
573 An alignment bug that caused a crash in the LZX decompressor on some
576 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
577 the WIM header when restoring the previous state of a WIM it failed to
580 Added a workaround to avoid an access denied error on Windows when
581 replacing a WIM file that another process has opened.
584 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
585 needed to be handled.
587 A bug in the interpretation of negative IMAGE indices in the
588 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
589 `wimlib-imagex append' has been fixed.
591 A workaround has been added to successfully apply security descriptors
592 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
593 2013.1.13 or earlier.
595 `wimlib-imagex capture' can now accept the '--delta-from' option
599 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
600 to standard output and applying images from standard input, but they are
601 not compatible with Microsoft's software and are not created by default.
602 See the documentation for --pipable flag of `wimlib-imagex capture' for
605 To better support incremental backups, added support for declaring an
606 image as a modified form of another image. See the documentation for
607 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
610 Added supported for "delta" WIMs. See the documentation for the
611 '--delta-from' option of `wimlib-imagex capture'.
613 The library support for managing split WIMs has been changed to support
614 other arrangements, such as delta WIMs, and be easier to use. This
615 change is visible in `wimlib-imagex', which also can now accept the
616 '--ref' option multiple times, and also now supports "delta" WIMs as
619 wimlib now preserves WIM integrity tables by default, even if
620 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
621 behavior of `wimlib-imagex' whenever the WIM being operated on contains
622 an integrity table and the '--check' option is not specified.
624 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
625 (when --compress is not specified). This provides the best compression
626 ratio by default, which is usually what is desired, at a cost of some
629 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
630 is the command as in `wimlib-imagex COMMAND'; for example, it can be
631 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
632 appropriate hard links are created in UNIX installations of
633 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
634 batch files that emulate this behavior are generated.
636 Security descriptors are now extracted correctly on Windows.
638 Fixed archiving DOS names in NTFS-3g capture mode.
640 The extraction code has been rewritten and it will now be easier to
641 support new features on all supported backends (currently Win32, UNIX,
642 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
643 now supported on all backends, not just UNIX.
645 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
646 than the WAIK itself.
648 wimlib_global_init() now, by default, attempts to acquire additional
649 privileges on Windows, so library clients need not do this.
651 This update bumps the shared library version number up to 9, since it is
652 not binary compatibible with previous releases.
655 Fixed bug in `wimlib-imagex export' that made it impossible to export an
656 image from a WIM that is readonly at the filesystem level.
658 Return error code rather than segfaulting when trying to list files from
659 a non-first part of a split WIM.
661 Joining a WIM will now preserve the RP_FIX and READONLY flags.
664 On Windows, paths given to wimlib-imagex are now treated case
667 Improved behavior regarding invalid filenames; in particular, on
668 Windows, wimlib-imagex will, when extracting, now omit (with an option
669 to override this default) filenames differing only in case, or filenames
670 containing characters not valid on Windows.
672 On Windows, wimlib now supports capturing and extracting long paths
673 (longer than the so-called MAX_PATH).
675 On Windows, `wimlib-imagex update' now acquires proper privileges when
676 running as an Administrator.
678 `wimlib-imagex update' will now complain if no image is specified when
679 trying to update a multi-image WIM.
681 `wimlib-imagex update' now supports specifying a single update command
682 directly on the command line using the --command option.
684 wimlib-imagex will now choose different units for progress messages,
685 depending on the amount of data that needs to be processed.
687 `wimlib-imagex append' will now generate a unique WIM image name if no
688 name is specified and the defaulted name already exists in the WIM.
690 wimlib now allows you to create unnamed WIM images, which can then only
691 be referred to by index.
693 wimlib now allows you to explicitly declare you want write access to a
694 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
697 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
700 Progress callbacks have been added to wimlib's wimlib_update_image()
703 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
704 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
707 NTFS-3g capture now only warns about two conditions previously treated
710 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
713 wimlib now correctly detects and returns an error when reading a WIM
714 image with a cyclic directory structure. (Fun fact: such a WIM will
715 crash Microsoft's software.)
718 Added new "extract" and "update" subcommands to wimlib-imagex, along
719 with associated APIs in the library. These commands are intended mainly
720 for Windows use but can be used on UNIX as well.
722 Many documentation improvements.
724 Fixed a bug in the Windows build where relative symbolic links were not
725 captured in reparse-point fixup mode.
727 Fixed a bug in the Windows build where file handles were left open to
728 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
730 Fixed a bug in the Windows build of wimlib-imagex where globbing
731 split-WIM parts could cause the program to crash.
733 Fixed a bug where the creation time of WIM images would be shown instead
734 of the last modification time.
736 With the Windows build it is now possible to restore a WIM containing
737 symbolic links as a non-Administrator; however you will receive warnings
738 about not being able to extract the symbolic links.
741 Capturing a WIM image should now be significantly faster in most cases
742 due to improved use of the operating system's cache and avoiding reading
743 files twice whenever possible.
745 The Windows build should now work on Windows XP.
747 The Windows build now supports capturing and restoring hidden,
748 compressed, sparse, and encrypted files.
750 The Windows build now supports capturing and applying WIM images from
751 filesystems other than NTFS (with some reduced functionality).
753 The Windows build now extracts short names correctly.
755 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
756 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
757 capture' and `wimlib-imagex apply'.
759 The performance of splitting and joining WIMs should be slightly
762 The LZX and XPRESS compression and decompression functions are now
763 exported from the library.
766 Improvements and bugfixes for the Windows build.
768 Added --strict-acls options.
770 Fixed the way that wimlib determines the order of images in the WIM.
773 Since wimlib can now be used on Windows, wimlib's implementation of
774 ImageX has been renamed to wimlib-imagex to avoid confusion with
775 Microsoft's implementation of ImageX, which would have the same file
776 name ("imagex.exe"). If you really don't like this you can pass the
777 --with-imagex-progname option to `configure' to choose a different name,
778 or even simply rename the binary yourself (but the former way will
779 configure the man pages to use the chosen name).
781 Various bugs fixed in the Windows build. Mainly to do with capturing
782 and restoring alternate data streams correctly in weird cases, and
783 requesting the correct privileges when opening files. Also added the
784 --noacls options to wimlib-imagex capture, append, and apply.
786 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
787 dynamically loaded, so this may make the library compatible with Windows
788 XP (however, there may still be other problems).
791 Added experimental support for native Windows builds. Binaries can be
792 downloaded from the SourceForge page.
794 --source-list option added to `imagex capture' and `imagex append'.
796 Better support for different character encodings.
799 Storing UNIX file owners, groups, and modes in WIM images is now
800 possible using `imagex capture' with the --unix-data flag.
802 Minor bug fixes and documentation fixes.
805 NTFS capture: Fixed capturing duplicate reparse points.
807 NTFS capture: Capture first unnamed stream if there are more than one
808 (print warning instead of error).
810 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
813 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
816 Update to work with ntfs-3g version 2013.1.13.
819 Fixed truncating file to shorter but non-zero length on read-write
822 Various code cleanups and minor documentation fixes.
825 LZX and XPRESS decompression have received some additional optimizations
826 and should now be even faster. (Although, they were already pretty
827 fast--- much faster than typical I/O speeds.)
829 Fixed a bug introduced in v1.2.1 that would cause a directory tree
830 containing hard links to be captured incorrectly in some cases.
833 By default, unmounting a read-write mounted WIM with 'imagex unmount
834 --commit' will now change the WIM in-place without needing to write the
835 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
838 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
839 for a response from the daemon servicing the mounted WIM. Instead,
840 every second 'imagex unmount' will check if the daemon is still alive,
841 and keep waiting if so, otherwise terminate with an error.
843 'imagex unmount --commit' on a read-write mounted WIM will now print
844 progress information regarding the writing of new or modified streams
845 the WIM, just like when capturing or appending a WIM.
847 A small change has been made to XPRESS compression and it should improve
848 the compression ratio slightly.
850 A change was made that may improve performance slightly when applying a
851 WIM image to a NTFS volume.
853 Microsoft has managed to introduce even more bugs into their software,
854 and now the WIMs for Windows 8 have incorrect (too low) reference counts
855 for some streams. This is unsafe because such streams can be removed
856 when they are in actuality still referenced in the WIM (perhaps by a
857 different image). wimlib will now work around this problem by fixing
858 the stream reference counts. This is only done when wimlib_delete_image() is
859 called ('imagex delete') or when wimlib_mount_image() is called with
860 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
861 requires reading the metadata for all images in the WIM, so this will
862 make these operations noticably slower on WIMs with multiple images.
864 Various other bugfixes.
867 Appending images to a WIM is now be done by default without re-building
868 the whole WIM. Use the --rebuild flag to get the old behavior (which
869 was to re-build the entire WIM when a new image is appended).
871 A new command `imagex optimize' is now available to manually re-build a
872 WIM that has wasted space due to repeated appends.
874 Progress information has been improved, and now arbitrary callback
875 functions can be used to show the progress of a WIM operation.
877 A possible bug with changing the bootable image of a WIM was fixed.
879 Some advisory locking is now done to prevent two processes from
880 modifying a WIM at the same time (but only in some cases). For example,
881 you cannot mount two images from a WIM read-write at the same time.
883 Some functions have been reorganized:
884 * wimlib_mount() renamed to wimlib_mount_image().
885 * wimlib_unmount() renamed to wimlib_unmount_image().
886 * wimlib_overwrite_xml_and_header() removed as
887 wimlib_overwrite() suffices now.
888 * wimlib_apply_image_to_ntfs_volume() removed as
889 wimlib_extract_image() suffices now.
890 * wimlib_add_image_from_ntfs_volume() removed as
891 * wimlib_add_image() suffices now.
893 Previously, the soname of libwim.so has been 0.0.0, despite many
894 interface changes. The soname is now updated to 1.0.0 and will now be
895 updated each release.
898 Resources will now be compressed using multiple threads by default.
899 (This applies to `imagex capture', `imagex append', and `imagex
902 Some performance improvements in mounted WIMs.
904 More progress information is shown when capturing a WIM.
907 Lots of minor fixes, code cleanups, and some documentation updates.
908 Nothing in particular is really noteworthy.
911 LZX and XPRESS compression improvements.
913 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
914 Link Bytes of the WIM.
917 Fixed bug when capturing NTFS file with multiple named data streams.
919 Internally, we are now using inode structures, even though these don't
920 appear literally in the WIM file. This simplifies some of the code
921 (mainly for WIM mounting) and likely fixed a few problems, although it
925 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
929 Enough changes to call it version 1.0.0!
931 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
932 to a NTFS volume, is now supported.
934 Hard links and symbolic links have much improved support. They are
935 supported for WIM capture, WIM application, and mounted WIMs (you can
936 even make them on read-write mounted WIMs).
938 Alternate data streams are now supported on mounted WIMs through an
939 xattr or a Windows-style stream interface. Also they are supported when
940 capturing a WIM from NTFS or applying a WIM to NTFS.
942 Split WIMs are better supported. You may now apply an image directly
943 from a split WIM, mount an image from a split WIM read-only, or export
944 an image from a split WIM.
946 Using a capture configuration file is now supported (but not fully yet).
948 SHA1 message digests are checked in more places, so we can make sure
949 applied and captured data is correct.
951 Man pages have been updated and consolidated.
954 Fixed segfault when unmounting read-only WIM.
957 Support for joining and splitting WIMs.
958 Also, security data is now preserved by default.
961 Can now build with older gcc and system headers, like on CentOS 5.
964 Fixed bug that made it impossible to overwrite files in read-write
968 Write byte-order mark before WIM XML data. (imagex.exe requires this to
