2 Files with timestamps before the year 1970 are now extracted correctly
3 to UNIX-style filesystems, are displayed correctly by
4 'wimdir --detailed', and show up correctly in mounted WIM images.
6 Files with timestamps after the year 2038 are now displayed correctly by
7 the 32-bit Windows build of wimlib.
10 Fixed a data corruption bug (incorrect compression) when storing an
11 already highly-compressed file in an LZX-compressed WIM with a chunk
12 size greater than or equal to 64K. Note that this is not the default
13 setting and such WIMs are not supported by Microsoft's WIM software, so
14 only users who used the --chunk-size option to wimlib-imagex or the
15 wimlib_set_output_chunk_size() API function may have been affected.
16 This bug was introduced in wimlib v1.10.0. See
17 https://wimlib.net/forums/viewtopic.php?f=1&t=300 for more details.
19 On all platforms, sparse files are now extracted as sparse.
21 Sparse files captured from UNIX-style filesystems are now marked as
22 sparse in the resulting WIM image.
24 Added support for storing Linux-style extended attributes in WIM images.
25 When the --unix-data option is used on Linux, wimlib-imagex now captures
26 and applies extended attributes, in addition to the already-supported
27 standard UNIX file permissions (owner/group/mode) and special files.
29 --delta-from is now supported by wimappend. (Previously it was only
30 supported by wimcapture.)
32 On Windows, improved the way in which files deduplicated with Windows'
33 Data Deduplication feature are captured.
35 The development files needed to link with wimlib using Visual Studio are
36 now included in the Windows release archives.
38 wimlib.h can now be included by Visual Studio without errors.
40 The example programs can now be compiled in C++ mode, and they also now
43 Updated 'mkwinpeimg' to work correctly on images that have a "windows"
44 (lower case) directory rather than a "Windows" (upper case) directory.
46 Fixed configuring with --enable-ssse3-sha1 from release tarball
47 (the file nasm_lt.sh was missing).
49 Made some documentation improvements.
52 The LZX compression ratio has been slightly improved. The default mode,
53 LZX level 50, is now almost as good as the old LZX level 100, while
54 being nearly the same speed as before.
56 Decompression performance has been slightly improved.
58 Filenames are now always listed in NTFS collation order.
60 On UNIX-like systems, wimlib can now process Windows filenames that are
61 not valid Unicode due to the presence of unpaired surrogates.
63 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
64 addition of surrogate codepoints. Consequently, the environmental
65 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
66 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
68 wimlib no longer depends on iconv.
70 Reduced memory usage slightly.
72 When a WIM image is applied in NTFS-3G mode, security descriptors are
73 now created in NTFS v3.0 format when supported by the volume.
75 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
76 been removed. Users are advised to upgrade to a later version of
79 On Windows, wimlib now supports case-sensitive filename extraction when
80 supported by the underlying operating system and filesystem (operating
81 system support requires a registry setting).
84 On UNIX, wimlib can now overwrite readonly files when extracting.
86 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
87 NTFS permissions") set on some existing directories after extraction.
89 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
90 driver is not loaded, wimlib can now correctly register a new WIM file
91 with the target volume when the target volume previously had had WIM
94 Added a new testing program.
96 Clarified the main license text and updated public domain dedications
97 for certain files to be more thorough.
100 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
102 Reduced memory usage when exporting large numbers of WIM images.
104 Non UTF-8 locales are now detected correctly.
106 Addressed compiler warnings and enabled "silent" make rules by default.
108 Windows-specific updates:
109 Fixed a bug where duplicate backslashes could be generated in
110 link targets when extracting symbolic links and junctions.
112 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
113 work if their full path contained a space.
115 Fixed bugs related to scanning SMB filesystems.
117 Added warning message about known issue with WindowsApps folder.
119 Added instructions for building from source on Windows.
121 VSS support is no longer marked "experimental".
123 Added missing license file for libdivsufsort-lite.
126 Added experimental support for Windows VSS (Volume Shadow Copy Service).
127 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
128 create and use a temporary VSS snapshot when capturing a WIM image.
130 Implemented setting of Windows-specific XML information, such as
131 architecture, system root, and version details. This information is now
132 automatically set in newly captured WIM images, when appropriate.
134 Improved performance of directory tree scans on Windows.
136 On Windows, to improve capture performance, wimlib now sometimes opens
137 files by inode number rather than by path. This is enabled for
138 wimcapture and wimappend, but for now other applications have to opt-in.
140 The progress messages printed by wimlib-imagex while writing WIM files
141 have been slightly tweaked.
143 Progress information for directory tree scans now counts all hard links.
144 Also, on Windows "\\?\" is no longer stripped from the current path.
146 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
147 'wiminfo'. This option lets you assign values to elements in a WIM
148 file's XML document by name.
150 The wimlib_get_image_property() and wimlib_set_image_property() API
151 functions now support numerically indexed elements.
153 Fixed a bug where, on Windows, wimlib would change the security
154 descriptor of the target directory of an extraction even when the
155 '--no-acls' option was specified.
158 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
159 some Microsoft software would not correctly recognize data in the
160 resulting filesystem.
162 Made some small improvements to the compression algorithms:
163 LZX compression ratio was slightly improved.
164 XPRESS compression ratio and speed was slightly improved.
165 LZMS compression speed was slightly improved.
167 Improved handling of WIM XML data. wimlib no longer drops unrecognized
168 elements when exporting images. In addition, two API functions were
169 added for better access to elements in the XML document:
170 wimlib_get_image_property() and wimlib_set_image_property().
172 Added support for (unsafe) in-place compaction of WIM files.
174 Improved performance of image export by reusing metadata resources
175 instead of always rebuilding and recompressing them.
177 Improved performance of wimlib_update_image() by delaying the update to
178 the WIM's XML document until a write is requested.
180 On Windows, the target of an extraction may now be a reparse point
181 (which will be dereferenced).
183 On Windows, wimlib now correctly restores non-Microsoft reparse points.
184 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
186 On Windows, wimlib now has improved performance when archiving files
187 from a filesystem backed by a WIM (a "WIMBoot" setup).
189 Several improvements to System Compression (compact mode) support:
191 wof.sys (or wofadk.sys) is now automatically attached to the
192 target volume if needed.
194 Compact-mode extractions now work correctly with wofadk.sys on
195 older versions of Windows.
197 For compatibility with the Windows bootloader, the requested
198 compression format now is overridden on certain files.
200 Other minor bugfixes.
203 This release primarily contains various minor bug fixes and
204 improvements, including:
206 Improved handling of deep directory structures.
208 Fixed a bug where on 32-bit systems, the library could enter an
209 infinite loop if a WIM file was malformed in a specific way.
211 Added a workaround for a case where libntfs-3g may report
212 duplicate streams in an NTFS file.
214 Windows symbolic links and junctions in mounted WIM images are
215 now automatically rewritten to be valid in the mounted location.
217 Reparse point fixes: correctly handle the "ReparseReserved"
218 field, and correctly handle "empty" (data-less) reparse points.
220 On Windows, wimlib now acquires SeManageVolumePrivilege, which
221 is needed to create externally backed files using the
224 Improved validation of filenames.
226 Improved LZMS decompression speed.
228 The configure script now honors alternate pkg-config settings.
230 Links have been updated to point to the new website.
232 In addition, experimental support has been added for compressing
233 extracted files using System Compression on Windows 10. This
234 functionality is available through the new '--compact' option to
235 'wimapply' and 'wimextract' as well as new library flags.
238 Fixed a bug in the LZX decompressor: malicious input data could cause
239 out of bounds writes to memory (since wimlib v1.2.2).
241 The output of the 'wiminfo' command now consolidates various boolean
242 flags (such as "Relative path junction") into a single line.
244 A file can now have both an unnamed data stream ("file contents") and a
245 reparse point stream. Such files can exist as a result of the use of
246 certain Windows features, such as offline storage, including "OneDrive".
247 wimlib will now store and restore both streams on Windows as well as in
248 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
250 On Windows, named data streams of encrypted files are no longer stored
251 twice in WIM archives.
253 On Windows, named data streams are now correctly extracted to existing
254 "readonly" directories. Before, an error would be reported.
256 On Windows, it is now possible to do a "WIMBoot mode" extraction with
257 non-standalone WIMs such as delta WIMs.
259 On Windows, when doing an extraction in "WIMBoot mode", files larger
260 than 4 gigabytes are now never extracted as externally backed. This
261 works around a bug in Microsoft's "WOF" driver.
263 The '--enable-verify-compression' configure option has been removed. If
264 you want to verify a WIM file, use the 'wimverify' program.
266 The way the "file count", "directory count", "total bytes", and "hard
267 link bytes" image statistics (stored in the WIM XML data) is calculated
268 has been slightly changed.
270 In mounted WIM images, the disk usage provided for each file (st_blocks)
271 is now the compressed size rather than the uncompressed size.
273 The performance of the NTFS-3g and Windows capture modes has been
276 On UNIX-like systems, symbolic links whose targets contain the backslash
277 character are now handled correctly (losslessly).
280 Improved the LZX compressor. It is now 15-20% faster than before and
281 provides a slightly better compression ratio.
283 Improved the LZMS compressor. It now provides a compression ratio
284 slightly better than WIMGAPI while still being faster and using slightly
287 The compression chunk size in solid resources, e.g. when capturing or
288 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
289 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
290 better compression ratio and is the same value that WIMGAPI uses. The
291 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
292 lower than WIMGAPI's memory usage, but if it is too much, it is still
293 possible to choose a lower value, e.g. with the '--solid-chunk-size'
294 option to wimlib-imagex.
296 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
297 accept the 'K', 'M', and 'G' suffixes.
299 Files are now sorted by name extension when creating a solid WIM file.
301 Fixed various issues related to capture/apply of EFS-encrypted files on
304 The file list printed by 'wimdir' is now sorted by the platform-specific
305 case sensitivity setting, rather than always case sensitively. This
306 also affects the library function wimlib_iterate_dir_tree().
308 On Windows, some error and warning messages have been improved.
311 The Windows binary distribution no longer contains third party DLLs.
312 These dependencies are instead compiled directly into the libwim DLL.
314 Added more fixes for wimlib on non-x86 architectures such as ARM.
316 Extracting files to a Windows PE in-memory filesystem no longer fails if
317 the target files do not yet exist.
319 Improved the performance of XPRESS compression and LZMS decompression.
321 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
322 It will automatically be faster on newer Intel and AMD processors.
324 Removed the --with-imagex-progname and --enable-more-assertions
328 Fix for very slow export from solid WIM / ESD files.
330 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
332 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
333 may use this to treat some types of errors as non-fatal.
335 The library now permits making in-memory changes to a WIMStruct backed
336 by a read-only WIM file.
338 Fixes for "WIMBoot" extraction mode (Windows only):
340 When not using the WOF driver, extraction no longer fails if the
341 disk containing the WIM file has too many partitions.
343 When matching patterns in [PrepopulateList], all hard links of
344 each file are now considered.
346 The system registry files are now automatically treated as being
347 in [PrepopulateList].
349 Added a hack to try to work around an intermittent bug in
350 Microsoft's WOF (Windows Overlay Filesystem) driver.
353 Made more improvements to the XPRESS, LZX, and LZMS compressors.
355 A number of improvements to the Windows port:
357 Fixes for setting short filenames.
359 Faster "WIMBoot" extraction.
361 Updated and slimmed down the dependent DLLs.
363 ACL inheritence bits are now restored.
365 Mandatory integrity labels are now backed up and restored.
367 Added a workaround for an issue where in rare cases, wimlib could create
368 a compressed data stream that could not be read correctly by Windows
369 after an extraction in "WIMBoot" mode.
372 Added file count progress data for
373 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
374 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
376 Added support for testing file exclusions via the user-provided
379 Some documentation improvements.
381 Made some clarifications to the license text in the COPYING file.
384 Made more improvements to the XPRESS, LZX, and LZMS compressors.
386 The default compression mode for wimcapture is now LZX compression in
387 its default mode, which is the same as '--compress=maximum'.
389 You can now specify an optional integer compression level to the
390 '--compress' option; e.g. '--compress=lzx:75'.
392 Made a minor change to the LZMS compressor and decompressor to fix an
393 incompatibility with the Microsoft implementation. In the unlikely
394 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
395 earlier and a checksum error is reported when extracting files from it
396 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
399 Added 'verify' subcommand to wimlib-imagex.
401 Notable library changes:
403 Custom compressor parameters have been removed from the library
404 in favor of the simpler level-based API.
406 Decompressor parameters have been removed entirely.
408 Library users can now specify a custom file for warning and
409 error messages to be sent to, rather than the default of
412 New progress messages:
413 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
414 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
416 New function: wimlib_verify_wim().
419 Improved compression, decompression, and extraction performance.
421 Improved compatibility with version 3584 WIM / ESD files:
422 - Add support for reading and writing multiple solid blocks per
423 archive, which WIMGAPI/DISM can create when appending an image.
424 - Correctly create solid blocks larger than 4 GiB.
426 'add' commands passed to wimupdate will now replace existing
427 nondirectory files by default. Use the --no-replace option to get the
430 The license for the library now contains an exception that allows using
431 it under the LGPL. See the COPYING file for details.
433 In reparse-point fixup mode (the default for capture), symbolic links
434 and junctions that point outside the tree being captured are no longer
435 excluded from capture.
437 Added support for "WIMBoot" capture and extraction. See the
438 documentation for the new '--wimboot' option to wimcapture and wimapply
439 for more information.
441 On UNIX-like systems, you can now backup and restore device nodes, named
442 pipes, and sockets. In addition, 32-bit user and group IDs are now
445 The way that UNIX data is stored in WIM files has been changed. If you
446 captured any WIMs with the --unix-data option, to upgrade them you'll
447 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
448 re-capture them with --unix-data using this version.
450 wimlib now understands tagged metadata items, such as object IDs, that
451 can be stored in WIM directory entries.
453 Removed the --hardlink and --symlink options to wimapply, since I don't
454 think they are too useful and they got in the way of improving the code.
456 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
458 The 'mkwinpeimg' script now supports writing the ISO image to standard
461 The <ARCH> element in WIM XML data is now exported correctly.
463 On Windows, sparse file attributes are no longer set on extracted files.
464 Oddly enough, this actually saves disk space in some cases.
466 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
467 supported. Mounting WIM images now always requires extended attribute
468 support. Use --without-fuse to disable support for mounting WIM images;
469 this will also disable the need for extended attribute support.
471 Configuring with --enable-ssse3-sha1 now works correctly.
473 The shared library version has been bumped up. The main
474 incompatibilities are:
476 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
477 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
480 - User-provided progress functions are now registered using a
481 separate function, wimlib_register_progress_function(). The
482 'progress_func' argument to many functions no longer exists.
484 - The return value from user-provided progress functions is now
487 - A context argument has been added to the prototype of
488 user-provided progress functions.
490 - 'struct wimlib_capture_config' has been removed. The library
491 now takes the path to the configuration file directly. This
492 affects wimlib_add_image(), wimlib_add_image_multisource(),
493 and wimlib_update_image(). However, a NULL value passed in
494 the argument retains the same meaning.
496 - Removed deprecated functions: some (de)compression functions,
497 wimlib_extract_files(), and wimlib_print_metadata().
499 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
500 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
501 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
503 - Removed some progress messages:
504 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
505 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
506 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
509 - Removed some error codes. Numbering stays the same.
511 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
512 WIMLIB_UNMOUNT_FLAG_FORCE.
514 - WIM paths passed to progress functions now have a leading
518 Case-insensitive comparisons of strings (e.g. filenames) containing
519 UTF-16 codepoints above 32767 are now done correctly.
521 Fixed build failure on Mac OS X.
523 wimunmount now provides the '--new-image' option to cause changes to a
524 read-write mounted image to be committed as a new image rather than as
525 an update of the mounted image. (The corresponding new library flag is
526 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
528 The LZMS ("recovery") compression chunk size, or "dictionary size", may
529 now be up to 1 GiB (1,073,741,824 bytes).
531 The performance of LZX ("maximum") and LZMS ("recovery") compression
532 with large chunk sizes has been slightly improved.
535 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
536 decompressed correctly.
538 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
539 occurred in an unlikely case, and due to validity checks it did not
540 affect successfully created archives.
542 Fixed a minor compatibility issue with the LZMS compressor and
543 decompressor. This is *not* the default compression type and was only
544 introduced in v1.6.0. In the unlikely event that you created an
545 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
546 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
549 Memory usage for LZMS and LZX compression has been decreased.
551 wimextract now allows wildcard characters in paths specified on the
552 command line. Also, the '--strict-wildcards' option has been removed
553 and replaced with the inverse option '--nullglob'. See the
554 documentation for wimextract for more details and changes.
556 The wimlib_extract_files() function is now considered deprecated in
557 favor of wimlib_extract_paths().
559 Fixed more permissions problems when extracting files on Windows.
561 A new '--no-attributes' option has been added to wimapply and
562 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
564 The default chunk size is now set correctly when changing the
565 compression type of a WIM, for example with 'wimoptimize'.
567 The '--metadata' option to wiminfo has been replaced with the
568 '--detailed' option to wimdir.
570 In relevant wimlib-imagex commands, '--solid' may now be used as an
571 alias for '--pack-streams'.
574 Support for extracting and updating the new version 3584 WIMs has been
575 added. These WIMs typically pack many streams ("files") together into a
576 single compressed resource, thereby saving space. This degrades the
577 performance of random access (such as that which occurs on a mounted
578 image), but optimizations have been implemented for extraction. These
579 new WIM files also typically use a new compression format (LZMS), which
580 is similar to LZMA and can offer a better compression ratio than LZX.
581 These new WIM files can be created using `wimcapture' with
582 the '--compress=lzms --pack-streams' options. Note: this new WIM format
583 is used by the Windows 8 web downloader, but important segments of the
584 raw '.esd' files are encrypted, so wimlib will not be able to extract
585 such files until they are first decrypted.
587 wimlib now supports extracting files and directories from a WIM image
588 based on a "listfile" that itself contains the list of paths to extract.
589 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
590 and for the library itself, the new APIs are wimlib_extract_pathlist()
591 and wimlib_extract_paths(). Path globs containing wildcard characters
594 For searching WIM files, wimlib now has configurable case sensitivity.
595 The default on Windows is still case-insensitive and the default on
596 UNIX-like systems is still case-sensitive, but this can be overridden
597 on either platform through flags to wimlib_global_init(). For
598 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
599 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
602 Support for compression chunk sizes greater than the default of 32768
603 bytes has been added. A larger chunk size typically results in a better
604 compression ratio. However, the MS implementation is seemingly not
605 compatible with all chunk sizes, especially for LZX compression, so the
606 defaults remain unchanged, with the exception of the new LZMS-compressed
607 WIMs, which use a larger chunk size by default.
609 The compression/decompression API exported by wimlib has been changed.
610 Now one set of functions handles all supported compression formats.
612 `wimcapture' and `wimappend' will now display the progress of scanning
613 the directory tree to capture, in addition to the progress of writing
614 data to the WIM. The '--verbose' option no longer does anything. The
615 library API change for this is the addition of several members to
616 `struct wimlib_progress_info_scan' available to progress callbacks.
618 `mkwinpeimg' now correctly handles the '--start-script' option when the
619 start script is not in the working directory.
621 Sequential extraction, previously requested by using
622 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
623 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
624 behavior (extract in file order).
627 The new LZX compressor added in v1.5.2 has been improved and is now
628 enabled by default, except when `wimcapture' or `wimappend' is run
629 *without* the '--compress' option, in which case the faster LZX
630 compressor is used (the same as before). This behavior is reasonably
631 consistent with ImageX which actually uses "fast" (XPRESS) compression
632 by default. In those cases, use '--compress=maximum' to explicitly
633 capture a WIM image using the new (slower but better) LZX compressor.
635 The '--compress-slow' option still exists to `wimlib-imagex optimize',
636 but its new behavior is to tweak the new LZX compressor even more to
637 produce an even better compression ratio at the cost of more time spent
640 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
641 which recompresses the WIM file using the specified compression TYPE.
642 The new library API function used for this is
643 wimlib_set_output_compression_type().
645 Added the wimlib_get_xml_data() function to allow library clients to
646 easily retrieve the raw XML data from a WIM file if needed.
648 Fixed a bug that could cause an error code to be incorrectly returned
649 when writing XML data containing a <WINDOWS> element.
651 Mounted WIM images will now correctly show the default file stream even
652 if appears in the alternate data stream entries of the corresponding WIM
656 Added a new experimental LZX compressor which can be enabled by passing
657 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
658 optimize'. (The latter is only applicable if the WIM is already
659 LZX-compressed and the '--recompress' option is also given.) The
660 experimental compressor is much slower but compresses the data slightly
661 more --- currently usually to within a fraction of a percent of the
662 results from WIMGAPI/ImageX.
664 A workaround has been added for compatibility with versions of WinPE
665 that interpret alternate data stream entries in the boot WIM
668 An alignment bug that caused a crash in the LZX decompressor on some
671 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
672 the WIM header when restoring the previous state of a WIM it failed to
675 Added a workaround to avoid an access denied error on Windows when
676 replacing a WIM file that another process has opened.
679 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
680 needed to be handled.
682 A bug in the interpretation of negative IMAGE indices in the
683 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
684 `wimlib-imagex append' has been fixed.
686 A workaround has been added to successfully apply security descriptors
687 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
688 2013.1.13 or earlier.
690 `wimlib-imagex capture' can now accept the '--delta-from' option
694 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
695 to standard output and applying images from standard input, but they are
696 not compatible with Microsoft's software and are not created by default.
697 See the documentation for --pipable flag of `wimlib-imagex capture' for
700 To better support incremental backups, added support for declaring an
701 image as a modified form of another image. See the documentation for
702 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
705 Added supported for "delta" WIMs. See the documentation for the
706 '--delta-from' option of `wimlib-imagex capture'.
708 The library support for managing split WIMs has been changed to support
709 other arrangements, such as delta WIMs, and be easier to use. This
710 change is visible in `wimlib-imagex', which also can now accept the
711 '--ref' option multiple times, and also now supports "delta" WIMs as
714 wimlib now preserves WIM integrity tables by default, even if
715 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
716 behavior of `wimlib-imagex' whenever the WIM being operated on contains
717 an integrity table and the '--check' option is not specified.
719 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
720 (when --compress is not specified). This provides the best compression
721 ratio by default, which is usually what is desired, at a cost of some
724 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
725 is the command as in `wimlib-imagex COMMAND'; for example, it can be
726 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
727 appropriate hard links are created in UNIX installations of
728 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
729 batch files that emulate this behavior are generated.
731 Security descriptors are now extracted correctly on Windows.
733 Fixed archiving DOS names in NTFS-3g capture mode.
735 The extraction code has been rewritten and it will now be easier to
736 support new features on all supported backends (currently Win32, UNIX,
737 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
738 now supported on all backends, not just UNIX.
740 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
741 than the WAIK itself.
743 wimlib_global_init() now, by default, attempts to acquire additional
744 privileges on Windows, so library clients need not do this.
746 This update bumps the shared library version number up to 9, since it is
747 not binary compatibible with previous releases.
750 Fixed bug in `wimlib-imagex export' that made it impossible to export an
751 image from a WIM that is readonly at the filesystem level.
753 Return error code rather than segfaulting when trying to list files from
754 a non-first part of a split WIM.
756 Joining a WIM will now preserve the RP_FIX and READONLY flags.
759 On Windows, paths given to wimlib-imagex are now treated case
762 Improved behavior regarding invalid filenames; in particular, on
763 Windows, wimlib-imagex will, when extracting, now omit (with an option
764 to override this default) filenames differing only in case, or filenames
765 containing characters not valid on Windows.
767 On Windows, wimlib now supports capturing and extracting long paths
768 (longer than the so-called MAX_PATH).
770 On Windows, `wimlib-imagex update' now acquires proper privileges when
771 running as an Administrator.
773 `wimlib-imagex update' will now complain if no image is specified when
774 trying to update a multi-image WIM.
776 `wimlib-imagex update' now supports specifying a single update command
777 directly on the command line using the --command option.
779 wimlib-imagex will now choose different units for progress messages,
780 depending on the amount of data that needs to be processed.
782 `wimlib-imagex append' will now generate a unique WIM image name if no
783 name is specified and the defaulted name already exists in the WIM.
785 wimlib now allows you to create unnamed WIM images, which can then only
786 be referred to by index.
788 wimlib now allows you to explicitly declare you want write access to a
789 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
792 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
795 Progress callbacks have been added to wimlib's wimlib_update_image()
798 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
799 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
802 NTFS-3g capture now only warns about two conditions previously treated
805 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
808 wimlib now correctly detects and returns an error when reading a WIM
809 image with a cyclic directory structure. (Fun fact: such a WIM will
810 crash Microsoft's software.)
813 Added new "extract" and "update" subcommands to wimlib-imagex, along
814 with associated APIs in the library. These commands are intended mainly
815 for Windows use but can be used on UNIX as well.
817 Many documentation improvements.
819 Fixed a bug in the Windows build where relative symbolic links were not
820 captured in reparse-point fixup mode.
822 Fixed a bug in the Windows build where file handles were left open to
823 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
825 Fixed a bug in the Windows build of wimlib-imagex where globbing
826 split-WIM parts could cause the program to crash.
828 Fixed a bug where the creation time of WIM images would be shown instead
829 of the last modification time.
831 With the Windows build it is now possible to restore a WIM containing
832 symbolic links as a non-Administrator; however you will receive warnings
833 about not being able to extract the symbolic links.
836 Capturing a WIM image should now be significantly faster in most cases
837 due to improved use of the operating system's cache and avoiding reading
838 files twice whenever possible.
840 The Windows build should now work on Windows XP.
842 The Windows build now supports capturing and restoring hidden,
843 compressed, sparse, and encrypted files.
845 The Windows build now supports capturing and applying WIM images from
846 filesystems other than NTFS (with some reduced functionality).
848 The Windows build now extracts short names correctly.
850 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
851 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
852 capture' and `wimlib-imagex apply'.
854 The performance of splitting and joining WIMs should be slightly
857 The LZX and XPRESS compression and decompression functions are now
858 exported from the library.
861 Improvements and bugfixes for the Windows build.
863 Added --strict-acls options.
865 Fixed the way that wimlib determines the order of images in the WIM.
868 Since wimlib can now be used on Windows, wimlib's implementation of
869 ImageX has been renamed to wimlib-imagex to avoid confusion with
870 Microsoft's implementation of ImageX, which would have the same file
871 name ("imagex.exe"). If you really don't like this you can pass the
872 --with-imagex-progname option to `configure' to choose a different name,
873 or even simply rename the binary yourself (but the former way will
874 configure the man pages to use the chosen name).
876 Various bugs fixed in the Windows build. Mainly to do with capturing
877 and restoring alternate data streams correctly in weird cases, and
878 requesting the correct privileges when opening files. Also added the
879 --noacls options to wimlib-imagex capture, append, and apply.
881 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
882 dynamically loaded, so this may make the library compatible with Windows
883 XP (however, there may still be other problems).
886 Added experimental support for native Windows builds. Binaries can be
887 downloaded from the SourceForge page.
889 --source-list option added to `imagex capture' and `imagex append'.
891 Better support for different character encodings.
894 Storing UNIX file owners, groups, and modes in WIM images is now
895 possible using `imagex capture' with the --unix-data flag.
897 Minor bug fixes and documentation fixes.
900 NTFS capture: Fixed capturing duplicate reparse points.
902 NTFS capture: Capture first unnamed stream if there are more than one
903 (print warning instead of error).
905 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
908 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
911 Update to work with ntfs-3g version 2013.1.13.
914 Fixed truncating file to shorter but non-zero length on read-write
917 Various code cleanups and minor documentation fixes.
920 LZX and XPRESS decompression have received some additional optimizations
921 and should now be even faster. (Although, they were already pretty
922 fast--- much faster than typical I/O speeds.)
924 Fixed a bug introduced in v1.2.1 that would cause a directory tree
925 containing hard links to be captured incorrectly in some cases.
928 By default, unmounting a read-write mounted WIM with 'imagex unmount
929 --commit' will now change the WIM in-place without needing to write the
930 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
933 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
934 for a response from the daemon servicing the mounted WIM. Instead,
935 every second 'imagex unmount' will check if the daemon is still alive,
936 and keep waiting if so, otherwise terminate with an error.
938 'imagex unmount --commit' on a read-write mounted WIM will now print
939 progress information regarding the writing of new or modified streams
940 the WIM, just like when capturing or appending a WIM.
942 A small change has been made to XPRESS compression and it should improve
943 the compression ratio slightly.
945 A change was made that may improve performance slightly when applying a
946 WIM image to a NTFS volume.
948 Microsoft has managed to introduce even more bugs into their software,
949 and now the WIMs for Windows 8 have incorrect (too low) reference counts
950 for some streams. This is unsafe because such streams can be removed
951 when they are in actuality still referenced in the WIM (perhaps by a
952 different image). wimlib will now work around this problem by fixing
953 the stream reference counts. This is only done when wimlib_delete_image() is
954 called ('imagex delete') or when wimlib_mount_image() is called with
955 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
956 requires reading the metadata for all images in the WIM, so this will
957 make these operations noticably slower on WIMs with multiple images.
959 Various other bugfixes.
962 Appending images to a WIM is now be done by default without re-building
963 the whole WIM. Use the --rebuild flag to get the old behavior (which
964 was to re-build the entire WIM when a new image is appended).
966 A new command `imagex optimize' is now available to manually re-build a
967 WIM that has wasted space due to repeated appends.
969 Progress information has been improved, and now arbitrary callback
970 functions can be used to show the progress of a WIM operation.
972 A possible bug with changing the bootable image of a WIM was fixed.
974 Some advisory locking is now done to prevent two processes from
975 modifying a WIM at the same time (but only in some cases). For example,
976 you cannot mount two images from a WIM read-write at the same time.
978 Some functions have been reorganized:
979 * wimlib_mount() renamed to wimlib_mount_image().
980 * wimlib_unmount() renamed to wimlib_unmount_image().
981 * wimlib_overwrite_xml_and_header() removed as
982 wimlib_overwrite() suffices now.
983 * wimlib_apply_image_to_ntfs_volume() removed as
984 wimlib_extract_image() suffices now.
985 * wimlib_add_image_from_ntfs_volume() removed as
986 * wimlib_add_image() suffices now.
988 Previously, the soname of libwim.so has been 0.0.0, despite many
989 interface changes. The soname is now updated to 1.0.0 and will now be
990 updated each release.
993 Resources will now be compressed using multiple threads by default.
994 (This applies to `imagex capture', `imagex append', and `imagex
997 Some performance improvements in mounted WIMs.
999 More progress information is shown when capturing a WIM.
1002 Lots of minor fixes, code cleanups, and some documentation updates.
1003 Nothing in particular is really noteworthy.
1006 LZX and XPRESS compression improvements.
1008 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
1009 Link Bytes of the WIM.
1012 Fixed bug when capturing NTFS file with multiple named data streams.
1014 Internally, we are now using inode structures, even though these don't
1015 appear literally in the WIM file. This simplifies some of the code
1016 (mainly for WIM mounting) and likely fixed a few problems, although it
1020 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
1024 Enough changes to call it version 1.0.0!
1026 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
1027 to a NTFS volume, is now supported.
1029 Hard links and symbolic links have much improved support. They are
1030 supported for WIM capture, WIM application, and mounted WIMs (you can
1031 even make them on read-write mounted WIMs).
1033 Alternate data streams are now supported on mounted WIMs through an
1034 xattr or a Windows-style stream interface. Also they are supported when
1035 capturing a WIM from NTFS or applying a WIM to NTFS.
1037 Split WIMs are better supported. You may now apply an image directly
1038 from a split WIM, mount an image from a split WIM read-only, or export
1039 an image from a split WIM.
1041 Using a capture configuration file is now supported (but not fully yet).
1043 SHA1 message digests are checked in more places, so we can make sure
1044 applied and captured data is correct.
1046 Man pages have been updated and consolidated.
1049 Fixed segfault when unmounting read-only WIM.
1052 Support for joining and splitting WIMs.
1053 Also, security data is now preserved by default.
1056 Can now build with older gcc and system headers, like on CentOS 5.
1059 Fixed bug that made it impossible to overwrite files in read-write
1063 Write byte-order mark before WIM XML data. (imagex.exe requires this to
