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 On UNIX-like systems, wimlib can now process Windows filenames that are
9 not valid Unicode due to the presence of unpaired surrogates.
11 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
12 addition of surrogate codepoints. Consequently, the environmental
13 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
14 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
16 wimlib no longer depends on iconv.
18 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
19 been removed. Users are advised to upgrade to a later version of
23 On UNIX, wimlib can now overwrite readonly files when extracting.
25 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
26 NTFS permissions") set on some existing directories after extraction.
28 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
29 driver is not loaded, wimlib can now correctly register a new WIM file
30 with the target volume when the target volume previously had had WIM
33 Added a new testing program.
35 Clarified the main license text and updated public domain dedications
36 for certain files to be more thorough.
39 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
41 Reduced memory usage when exporting large numbers of WIM images.
43 Non UTF-8 locales are now detected correctly.
45 Addressed compiler warnings and enabled "silent" make rules by default.
47 Windows-specific updates:
48 Fixed a bug where duplicate backslashes could be generated in
49 link targets when extracting symbolic links and junctions.
51 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
52 work if their full path contained a space.
54 Fixed bugs related to scanning SMB filesystems.
56 Added warning message about known issue with WindowsApps folder.
58 Added instructions for building from source on Windows.
60 VSS support is no longer marked "experimental".
62 Added missing license file for libdivsufsort-lite.
65 Added experimental support for Windows VSS (Volume Shadow Copy Service).
66 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
67 create and use a temporary VSS snapshot when capturing a WIM image.
69 Implemented setting of Windows-specific XML information, such as
70 architecture, system root, and version details. This information is now
71 automatically set in newly captured WIM images, when appropriate.
73 Improved performance of directory tree scans on Windows.
75 On Windows, to improve capture performance, wimlib now sometimes opens
76 files by inode number rather than by path. This is enabled for
77 wimcapture and wimappend, but for now other applications have to opt-in.
79 The progress messages printed by wimlib-imagex while writing WIM files
80 have been slightly tweaked.
82 Progress information for directory tree scans now counts all hard links.
83 Also, on Windows "\\?\" is no longer stripped from the current path.
85 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
86 'wiminfo'. This option lets you assign values to elements in a WIM
87 file's XML document by name.
89 The wimlib_get_image_property() and wimlib_set_image_property() API
90 functions now support numerically indexed elements.
92 Fixed a bug where, on Windows, wimlib would change the security
93 descriptor of the target directory of an extraction even when the
94 '--no-acls' option was specified.
97 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
98 some Microsoft software would not correctly recognize data in the
101 Made some small improvements to the compression algorithms:
102 LZX compression ratio was slightly improved.
103 XPRESS compression ratio and speed was slightly improved.
104 LZMS compression speed was slightly improved.
106 Improved handling of WIM XML data. wimlib no longer drops unrecognized
107 elements when exporting images. In addition, two API functions were
108 added for better access to elements in the XML document:
109 wimlib_get_image_property() and wimlib_set_image_property().
111 Added support for (unsafe) in-place compaction of WIM files.
113 Improved performance of image export by reusing metadata resources
114 instead of always rebuilding and recompressing them.
116 Improved performance of wimlib_update_image() by delaying the update to
117 the WIM's XML document until a write is requested.
119 On Windows, the target of an extraction may now be a reparse point
120 (which will be dereferenced).
122 On Windows, wimlib now correctly restores non-Microsoft reparse points.
123 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
125 On Windows, wimlib now has improved performance when archiving files
126 from a filesystem backed by a WIM (a "WIMBoot" setup).
128 Several improvements to System Compression (compact mode) support:
130 wof.sys (or wofadk.sys) is now automatically attached to the
131 target volume if needed.
133 Compact-mode extractions now work correctly with wofadk.sys on
134 older versions of Windows.
136 For compatibility with the Windows bootloader, the requested
137 compression format now is overridden on certain files.
139 Other minor bugfixes.
142 This release primarily contains various minor bug fixes and
143 improvements, including:
145 Improved handling of deep directory structures.
147 Fixed a bug where on 32-bit systems, the library could enter an
148 infinite loop if a WIM file was malformed in a specific way.
150 Added a workaround for a case where libntfs-3g may report
151 duplicate streams in an NTFS file.
153 Windows symbolic links and junctions in mounted WIM images are
154 now automatically rewritten to be valid in the mounted location.
156 Reparse point fixes: correctly handle the "ReparseReserved"
157 field, and correctly handle "empty" (data-less) reparse points.
159 On Windows, wimlib now acquires SeManageVolumePrivilege, which
160 is needed to create externally backed files using the
163 Improved validation of filenames.
165 Improved LZMS decompression speed.
167 The configure script now honors alternate pkg-config settings.
169 Links have been updated to point to the new website.
171 In addition, experimental support has been added for compressing
172 extracted files using System Compression on Windows 10. This
173 functionality is available through the new '--compact' option to
174 'wimapply' and 'wimextract' as well as new library flags.
177 Fixed a bug in the LZX decompressor: malicious input data could cause
178 out of bounds writes to memory (since wimlib v1.2.2).
180 The output of the 'wiminfo' command now consolidates various boolean
181 flags (such as "Relative path junction") into a single line.
183 A file can now have both an unnamed data stream ("file contents") and a
184 reparse point stream. Such files can exist as a result of the use of
185 certain Windows features, such as offline storage, including "OneDrive".
186 wimlib will now store and restore both streams on Windows as well as in
187 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
189 On Windows, named data streams of encrypted files are no longer stored
190 twice in WIM archives.
192 On Windows, named data streams are now correctly extracted to existing
193 "readonly" directories. Before, an error would be reported.
195 On Windows, it is now possible to do a "WIMBoot mode" extraction with
196 non-standalone WIMs such as delta WIMs.
198 On Windows, when doing an extraction in "WIMBoot mode", files larger
199 than 4 gigabytes are now never extracted as externally backed. This
200 works around a bug in Microsoft's "WOF" driver.
202 The '--enable-verify-compression' configure option has been removed. If
203 you want to verify a WIM file, use the 'wimverify' program.
205 The way the "file count", "directory count", "total bytes", and "hard
206 link bytes" image statistics (stored in the WIM XML data) is calculated
207 has been slightly changed.
209 In mounted WIM images, the disk usage provided for each file (st_blocks)
210 is now the compressed size rather than the uncompressed size.
212 The performance of the NTFS-3g and Windows capture modes has been
215 On UNIX-like systems, symbolic links whose targets contain the backslash
216 character are now handled correctly (losslessly).
219 Improved the LZX compressor. It is now 15-20% faster than before and
220 provides a slightly better compression ratio.
222 Improved the LZMS compressor. It now provides a compression ratio
223 slightly better than WIMGAPI while still being faster and using slightly
226 The compression chunk size in solid resources, e.g. when capturing or
227 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
228 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
229 better compression ratio and is the same value that WIMGAPI uses. The
230 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
231 lower than WIMGAPI's memory usage, but if it is too much, it is still
232 possible to choose a lower value, e.g. with the '--solid-chunk-size'
233 option to wimlib-imagex.
235 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
236 accept the 'K', 'M', and 'G' suffixes.
238 Files are now sorted by name extension when creating a solid WIM file.
240 Fixed various issues related to capture/apply of EFS-encrypted files on
243 The file list printed by 'wimdir' is now sorted by the platform-specific
244 case sensitivity setting, rather than always case sensitively. This
245 also affects the library function wimlib_iterate_dir_tree().
247 On Windows, some error and warning messages have been improved.
250 The Windows binary distribution no longer contains third party DLLs.
251 These dependencies are instead compiled directly into the libwim DLL.
253 Added more fixes for wimlib on non-x86 architectures such as ARM.
255 Extracting files to a Windows PE in-memory filesystem no longer fails if
256 the target files do not yet exist.
258 Improved the performance of XPRESS compression and LZMS decompression.
260 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
261 It will automatically be faster on newer Intel and AMD processors.
263 Removed the --with-imagex-progname and --enable-more-assertions
267 Fix for very slow export from solid WIM / ESD files.
269 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
271 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
272 may use this to treat some types of errors as non-fatal.
274 The library now permits making in-memory changes to a WIMStruct backed
275 by a read-only WIM file.
277 Fixes for "WIMBoot" extraction mode (Windows only):
279 When not using the WOF driver, extraction no longer fails if the
280 disk containing the WIM file has too many partitions.
282 When matching patterns in [PrepopulateList], all hard links of
283 each file are now considered.
285 The system registry files are now automatically treated as being
286 in [PrepopulateList].
288 Added a hack to try to work around an intermittent bug in
289 Microsoft's WOF (Windows Overlay Filesystem) driver.
292 Made more improvements to the XPRESS, LZX, and LZMS compressors.
294 A number of improvements to the Windows port:
296 Fixes for setting short filenames.
298 Faster "WIMBoot" extraction.
300 Updated and slimmed down the dependent DLLs.
302 ACL inheritence bits are now restored.
304 Mandatory integrity labels are now backed up and restored.
306 Added a workaround for an issue where in rare cases, wimlib could create
307 a compressed data stream that could not be read correctly by Windows
308 after an extraction in "WIMBoot" mode.
311 Added file count progress data for
312 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
313 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
315 Added support for testing file exclusions via the user-provided
318 Some documentation improvements.
320 Made some clarifications to the license text in the COPYING file.
323 Made more improvements to the XPRESS, LZX, and LZMS compressors.
325 The default compression mode for wimcapture is now LZX compression in
326 its default mode, which is the same as '--compress=maximum'.
328 You can now specify an optional integer compression level to the
329 '--compress' option; e.g. '--compress=lzx:75'.
331 Made a minor change to the LZMS compressor and decompressor to fix an
332 incompatibility with the Microsoft implementation. In the unlikely
333 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
334 earlier and a checksum error is reported when extracting files from it
335 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
338 Added 'verify' subcommand to wimlib-imagex.
340 Notable library changes:
342 Custom compressor parameters have been removed from the library
343 in favor of the simpler level-based API.
345 Decompressor parameters have been removed entirely.
347 Library users can now specify a custom file for warning and
348 error messages to be sent to, rather than the default of
351 New progress messages:
352 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
353 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
355 New function: wimlib_verify_wim().
358 Improved compression, decompression, and extraction performance.
360 Improved compatibility with version 3584 WIM / ESD files:
361 - Add support for reading and writing multiple solid blocks per
362 archive, which WIMGAPI/DISM can create when appending an image.
363 - Correctly create solid blocks larger than 4 GiB.
365 'add' commands passed to wimupdate will now replace existing
366 nondirectory files by default. Use the --no-replace option to get the
369 The license for the library now contains an exception that allows using
370 it under the LGPL. See the COPYING file for details.
372 In reparse-point fixup mode (the default for capture), symbolic links
373 and junctions that point outside the tree being captured are no longer
374 excluded from capture.
376 Added support for "WIMBoot" capture and extraction. See the
377 documentation for the new '--wimboot' option to wimcapture and wimapply
378 for more information.
380 On UNIX-like systems, you can now backup and restore device nodes, named
381 pipes, and sockets. In addition, 32-bit user and group IDs are now
384 The way that UNIX data is stored in WIM files has been changed. If you
385 captured any WIMs with the --unix-data option, to upgrade them you'll
386 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
387 re-capture them with --unix-data using this version.
389 wimlib now understands tagged metadata items, such as object IDs, that
390 can be stored in WIM directory entries.
392 Removed the --hardlink and --symlink options to wimapply, since I don't
393 think they are too useful and they got in the way of improving the code.
395 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
397 The 'mkwinpeimg' script now supports writing the ISO image to standard
400 The <ARCH> element in WIM XML data is now exported correctly.
402 On Windows, sparse file attributes are no longer set on extracted files.
403 Oddly enough, this actually saves disk space in some cases.
405 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
406 supported. Mounting WIM images now always requires extended attribute
407 support. Use --without-fuse to disable support for mounting WIM images;
408 this will also disable the need for extended attribute support.
410 Configuring with --enable-ssse3-sha1 now works correctly.
412 The shared library version has been bumped up. The main
413 incompatibilities are:
415 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
416 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
419 - User-provided progress functions are now registered using a
420 separate function, wimlib_register_progress_function(). The
421 'progress_func' argument to many functions no longer exists.
423 - The return value from user-provided progress functions is now
426 - A context argument has been added to the prototype of
427 user-provided progress functions.
429 - 'struct wimlib_capture_config' has been removed. The library
430 now takes the path to the configuration file directly. This
431 affects wimlib_add_image(), wimlib_add_image_multisource(),
432 and wimlib_update_image(). However, a NULL value passed in
433 the argument retains the same meaning.
435 - Removed deprecated functions: some (de)compression functions,
436 wimlib_extract_files(), and wimlib_print_metadata().
438 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
439 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
440 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
442 - Removed some progress messages:
443 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
444 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
445 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
448 - Removed some error codes. Numbering stays the same.
450 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
451 WIMLIB_UNMOUNT_FLAG_FORCE.
453 - WIM paths passed to progress functions now have a leading
457 Case-insensitive comparisons of strings (e.g. filenames) containing
458 UTF-16 codepoints above 32767 are now done correctly.
460 Fixed build failure on Mac OS X.
462 wimunmount now provides the '--new-image' option to cause changes to a
463 read-write mounted image to be committed as a new image rather than as
464 an update of the mounted image. (The corresponding new library flag is
465 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
467 The LZMS ("recovery") compression chunk size, or "dictionary size", may
468 now be up to 1 GiB (1,073,741,824 bytes).
470 The performance of LZX ("maximum") and LZMS ("recovery") compression
471 with large chunk sizes has been slightly improved.
474 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
475 decompressed correctly.
477 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
478 occurred in an unlikely case, and due to validity checks it did not
479 affect successfully created archives.
481 Fixed a minor compatibility issue with the LZMS compressor and
482 decompressor. This is *not* the default compression type and was only
483 introduced in v1.6.0. In the unlikely event that you created an
484 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
485 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
488 Memory usage for LZMS and LZX compression has been decreased.
490 wimextract now allows wildcard characters in paths specified on the
491 command line. Also, the '--strict-wildcards' option has been removed
492 and replaced with the inverse option '--nullglob'. See the
493 documentation for wimextract for more details and changes.
495 The wimlib_extract_files() function is now considered deprecated in
496 favor of wimlib_extract_paths().
498 Fixed more permissions problems when extracting files on Windows.
500 A new '--no-attributes' option has been added to wimapply and
501 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
503 The default chunk size is now set correctly when changing the
504 compression type of a WIM, for example with 'wimoptimize'.
506 The '--metadata' option to wiminfo has been replaced with the
507 '--detailed' option to wimdir.
509 In relevant wimlib-imagex commands, '--solid' may now be used as an
510 alias for '--pack-streams'.
513 Support for extracting and updating the new version 3584 WIMs has been
514 added. These WIMs typically pack many streams ("files") together into a
515 single compressed resource, thereby saving space. This degrades the
516 performance of random access (such as that which occurs on a mounted
517 image), but optimizations have been implemented for extraction. These
518 new WIM files also typically use a new compression format (LZMS), which
519 is similar to LZMA and can offer a better compression ratio than LZX.
520 These new WIM files can be created using `wimcapture' with
521 the '--compress=lzms --pack-streams' options. Note: this new WIM format
522 is used by the Windows 8 web downloader, but important segments of the
523 raw '.esd' files are encrypted, so wimlib will not be able to extract
524 such files until they are first decrypted.
526 wimlib now supports extracting files and directories from a WIM image
527 based on a "listfile" that itself contains the list of paths to extract.
528 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
529 and for the library itself, the new APIs are wimlib_extract_pathlist()
530 and wimlib_extract_paths(). Path globs containing wildcard characters
533 For searching WIM files, wimlib now has configurable case sensitivity.
534 The default on Windows is still case-insensitive and the default on
535 UNIX-like systems is still case-sensitive, but this can be overridden
536 on either platform through flags to wimlib_global_init(). For
537 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
538 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
541 Support for compression chunk sizes greater than the default of 32768
542 bytes has been added. A larger chunk size typically results in a better
543 compression ratio. However, the MS implementation is seemingly not
544 compatible with all chunk sizes, especially for LZX compression, so the
545 defaults remain unchanged, with the exception of the new LZMS-compressed
546 WIMs, which use a larger chunk size by default.
548 The compression/decompression API exported by wimlib has been changed.
549 Now one set of functions handles all supported compression formats.
551 `wimcapture' and `wimappend' will now display the progress of scanning
552 the directory tree to capture, in addition to the progress of writing
553 data to the WIM. The '--verbose' option no longer does anything. The
554 library API change for this is the addition of several members to
555 `struct wimlib_progress_info_scan' available to progress callbacks.
557 `mkwinpeimg' now correctly handles the '--start-script' option when the
558 start script is not in the working directory.
560 Sequential extraction, previously requested by using
561 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
562 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
563 behavior (extract in file order).
566 The new LZX compressor added in v1.5.2 has been improved and is now
567 enabled by default, except when `wimcapture' or `wimappend' is run
568 *without* the '--compress' option, in which case the faster LZX
569 compressor is used (the same as before). This behavior is reasonably
570 consistent with ImageX which actually uses "fast" (XPRESS) compression
571 by default. In those cases, use '--compress=maximum' to explicitly
572 capture a WIM image using the new (slower but better) LZX compressor.
574 The '--compress-slow' option still exists to `wimlib-imagex optimize',
575 but its new behavior is to tweak the new LZX compressor even more to
576 produce an even better compression ratio at the cost of more time spent
579 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
580 which recompresses the WIM file using the specified compression TYPE.
581 The new library API function used for this is
582 wimlib_set_output_compression_type().
584 Added the wimlib_get_xml_data() function to allow library clients to
585 easily retrieve the raw XML data from a WIM file if needed.
587 Fixed a bug that could cause an error code to be incorrectly returned
588 when writing XML data containing a <WINDOWS> element.
590 Mounted WIM images will now correctly show the default file stream even
591 if appears in the alternate data stream entries of the corresponding WIM
595 Added a new experimental LZX compressor which can be enabled by passing
596 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
597 optimize'. (The latter is only applicable if the WIM is already
598 LZX-compressed and the '--recompress' option is also given.) The
599 experimental compressor is much slower but compresses the data slightly
600 more --- currently usually to within a fraction of a percent of the
601 results from WIMGAPI/ImageX.
603 A workaround has been added for compatibility with versions of WinPE
604 that interpret alternate data stream entries in the boot WIM
607 An alignment bug that caused a crash in the LZX decompressor on some
610 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
611 the WIM header when restoring the previous state of a WIM it failed to
614 Added a workaround to avoid an access denied error on Windows when
615 replacing a WIM file that another process has opened.
618 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
619 needed to be handled.
621 A bug in the interpretation of negative IMAGE indices in the
622 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
623 `wimlib-imagex append' has been fixed.
625 A workaround has been added to successfully apply security descriptors
626 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
627 2013.1.13 or earlier.
629 `wimlib-imagex capture' can now accept the '--delta-from' option
633 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
634 to standard output and applying images from standard input, but they are
635 not compatible with Microsoft's software and are not created by default.
636 See the documentation for --pipable flag of `wimlib-imagex capture' for
639 To better support incremental backups, added support for declaring an
640 image as a modified form of another image. See the documentation for
641 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
644 Added supported for "delta" WIMs. See the documentation for the
645 '--delta-from' option of `wimlib-imagex capture'.
647 The library support for managing split WIMs has been changed to support
648 other arrangements, such as delta WIMs, and be easier to use. This
649 change is visible in `wimlib-imagex', which also can now accept the
650 '--ref' option multiple times, and also now supports "delta" WIMs as
653 wimlib now preserves WIM integrity tables by default, even if
654 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
655 behavior of `wimlib-imagex' whenever the WIM being operated on contains
656 an integrity table and the '--check' option is not specified.
658 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
659 (when --compress is not specified). This provides the best compression
660 ratio by default, which is usually what is desired, at a cost of some
663 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
664 is the command as in `wimlib-imagex COMMAND'; for example, it can be
665 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
666 appropriate hard links are created in UNIX installations of
667 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
668 batch files that emulate this behavior are generated.
670 Security descriptors are now extracted correctly on Windows.
672 Fixed archiving DOS names in NTFS-3g capture mode.
674 The extraction code has been rewritten and it will now be easier to
675 support new features on all supported backends (currently Win32, UNIX,
676 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
677 now supported on all backends, not just UNIX.
679 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
680 than the WAIK itself.
682 wimlib_global_init() now, by default, attempts to acquire additional
683 privileges on Windows, so library clients need not do this.
685 This update bumps the shared library version number up to 9, since it is
686 not binary compatibible with previous releases.
689 Fixed bug in `wimlib-imagex export' that made it impossible to export an
690 image from a WIM that is readonly at the filesystem level.
692 Return error code rather than segfaulting when trying to list files from
693 a non-first part of a split WIM.
695 Joining a WIM will now preserve the RP_FIX and READONLY flags.
698 On Windows, paths given to wimlib-imagex are now treated case
701 Improved behavior regarding invalid filenames; in particular, on
702 Windows, wimlib-imagex will, when extracting, now omit (with an option
703 to override this default) filenames differing only in case, or filenames
704 containing characters not valid on Windows.
706 On Windows, wimlib now supports capturing and extracting long paths
707 (longer than the so-called MAX_PATH).
709 On Windows, `wimlib-imagex update' now acquires proper privileges when
710 running as an Administrator.
712 `wimlib-imagex update' will now complain if no image is specified when
713 trying to update a multi-image WIM.
715 `wimlib-imagex update' now supports specifying a single update command
716 directly on the command line using the --command option.
718 wimlib-imagex will now choose different units for progress messages,
719 depending on the amount of data that needs to be processed.
721 `wimlib-imagex append' will now generate a unique WIM image name if no
722 name is specified and the defaulted name already exists in the WIM.
724 wimlib now allows you to create unnamed WIM images, which can then only
725 be referred to by index.
727 wimlib now allows you to explicitly declare you want write access to a
728 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
731 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
734 Progress callbacks have been added to wimlib's wimlib_update_image()
737 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
738 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
741 NTFS-3g capture now only warns about two conditions previously treated
744 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
747 wimlib now correctly detects and returns an error when reading a WIM
748 image with a cyclic directory structure. (Fun fact: such a WIM will
749 crash Microsoft's software.)
752 Added new "extract" and "update" subcommands to wimlib-imagex, along
753 with associated APIs in the library. These commands are intended mainly
754 for Windows use but can be used on UNIX as well.
756 Many documentation improvements.
758 Fixed a bug in the Windows build where relative symbolic links were not
759 captured in reparse-point fixup mode.
761 Fixed a bug in the Windows build where file handles were left open to
762 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
764 Fixed a bug in the Windows build of wimlib-imagex where globbing
765 split-WIM parts could cause the program to crash.
767 Fixed a bug where the creation time of WIM images would be shown instead
768 of the last modification time.
770 With the Windows build it is now possible to restore a WIM containing
771 symbolic links as a non-Administrator; however you will receive warnings
772 about not being able to extract the symbolic links.
775 Capturing a WIM image should now be significantly faster in most cases
776 due to improved use of the operating system's cache and avoiding reading
777 files twice whenever possible.
779 The Windows build should now work on Windows XP.
781 The Windows build now supports capturing and restoring hidden,
782 compressed, sparse, and encrypted files.
784 The Windows build now supports capturing and applying WIM images from
785 filesystems other than NTFS (with some reduced functionality).
787 The Windows build now extracts short names correctly.
789 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
790 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
791 capture' and `wimlib-imagex apply'.
793 The performance of splitting and joining WIMs should be slightly
796 The LZX and XPRESS compression and decompression functions are now
797 exported from the library.
800 Improvements and bugfixes for the Windows build.
802 Added --strict-acls options.
804 Fixed the way that wimlib determines the order of images in the WIM.
807 Since wimlib can now be used on Windows, wimlib's implementation of
808 ImageX has been renamed to wimlib-imagex to avoid confusion with
809 Microsoft's implementation of ImageX, which would have the same file
810 name ("imagex.exe"). If you really don't like this you can pass the
811 --with-imagex-progname option to `configure' to choose a different name,
812 or even simply rename the binary yourself (but the former way will
813 configure the man pages to use the chosen name).
815 Various bugs fixed in the Windows build. Mainly to do with capturing
816 and restoring alternate data streams correctly in weird cases, and
817 requesting the correct privileges when opening files. Also added the
818 --noacls options to wimlib-imagex capture, append, and apply.
820 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
821 dynamically loaded, so this may make the library compatible with Windows
822 XP (however, there may still be other problems).
825 Added experimental support for native Windows builds. Binaries can be
826 downloaded from the SourceForge page.
828 --source-list option added to `imagex capture' and `imagex append'.
830 Better support for different character encodings.
833 Storing UNIX file owners, groups, and modes in WIM images is now
834 possible using `imagex capture' with the --unix-data flag.
836 Minor bug fixes and documentation fixes.
839 NTFS capture: Fixed capturing duplicate reparse points.
841 NTFS capture: Capture first unnamed stream if there are more than one
842 (print warning instead of error).
844 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
847 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
850 Update to work with ntfs-3g version 2013.1.13.
853 Fixed truncating file to shorter but non-zero length on read-write
856 Various code cleanups and minor documentation fixes.
859 LZX and XPRESS decompression have received some additional optimizations
860 and should now be even faster. (Although, they were already pretty
861 fast--- much faster than typical I/O speeds.)
863 Fixed a bug introduced in v1.2.1 that would cause a directory tree
864 containing hard links to be captured incorrectly in some cases.
867 By default, unmounting a read-write mounted WIM with 'imagex unmount
868 --commit' will now change the WIM in-place without needing to write the
869 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
872 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
873 for a response from the daemon servicing the mounted WIM. Instead,
874 every second 'imagex unmount' will check if the daemon is still alive,
875 and keep waiting if so, otherwise terminate with an error.
877 'imagex unmount --commit' on a read-write mounted WIM will now print
878 progress information regarding the writing of new or modified streams
879 the WIM, just like when capturing or appending a WIM.
881 A small change has been made to XPRESS compression and it should improve
882 the compression ratio slightly.
884 A change was made that may improve performance slightly when applying a
885 WIM image to a NTFS volume.
887 Microsoft has managed to introduce even more bugs into their software,
888 and now the WIMs for Windows 8 have incorrect (too low) reference counts
889 for some streams. This is unsafe because such streams can be removed
890 when they are in actuality still referenced in the WIM (perhaps by a
891 different image). wimlib will now work around this problem by fixing
892 the stream reference counts. This is only done when wimlib_delete_image() is
893 called ('imagex delete') or when wimlib_mount_image() is called with
894 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
895 requires reading the metadata for all images in the WIM, so this will
896 make these operations noticably slower on WIMs with multiple images.
898 Various other bugfixes.
901 Appending images to a WIM is now be done by default without re-building
902 the whole WIM. Use the --rebuild flag to get the old behavior (which
903 was to re-build the entire WIM when a new image is appended).
905 A new command `imagex optimize' is now available to manually re-build a
906 WIM that has wasted space due to repeated appends.
908 Progress information has been improved, and now arbitrary callback
909 functions can be used to show the progress of a WIM operation.
911 A possible bug with changing the bootable image of a WIM was fixed.
913 Some advisory locking is now done to prevent two processes from
914 modifying a WIM at the same time (but only in some cases). For example,
915 you cannot mount two images from a WIM read-write at the same time.
917 Some functions have been reorganized:
918 * wimlib_mount() renamed to wimlib_mount_image().
919 * wimlib_unmount() renamed to wimlib_unmount_image().
920 * wimlib_overwrite_xml_and_header() removed as
921 wimlib_overwrite() suffices now.
922 * wimlib_apply_image_to_ntfs_volume() removed as
923 wimlib_extract_image() suffices now.
924 * wimlib_add_image_from_ntfs_volume() removed as
925 * wimlib_add_image() suffices now.
927 Previously, the soname of libwim.so has been 0.0.0, despite many
928 interface changes. The soname is now updated to 1.0.0 and will now be
929 updated each release.
932 Resources will now be compressed using multiple threads by default.
933 (This applies to `imagex capture', `imagex append', and `imagex
936 Some performance improvements in mounted WIMs.
938 More progress information is shown when capturing a WIM.
941 Lots of minor fixes, code cleanups, and some documentation updates.
942 Nothing in particular is really noteworthy.
945 LZX and XPRESS compression improvements.
947 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
948 Link Bytes of the WIM.
951 Fixed bug when capturing NTFS file with multiple named data streams.
953 Internally, we are now using inode structures, even though these don't
954 appear literally in the WIM file. This simplifies some of the code
955 (mainly for WIM mounting) and likely fixed a few problems, although it
959 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
963 Enough changes to call it version 1.0.0!
965 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
966 to a NTFS volume, is now supported.
968 Hard links and symbolic links have much improved support. They are
969 supported for WIM capture, WIM application, and mounted WIMs (you can
970 even make them on read-write mounted WIMs).
972 Alternate data streams are now supported on mounted WIMs through an
973 xattr or a Windows-style stream interface. Also they are supported when
974 capturing a WIM from NTFS or applying a WIM to NTFS.
976 Split WIMs are better supported. You may now apply an image directly
977 from a split WIM, mount an image from a split WIM read-only, or export
978 an image from a split WIM.
980 Using a capture configuration file is now supported (but not fully yet).
982 SHA1 message digests are checked in more places, so we can make sure
983 applied and captured data is correct.
985 Man pages have been updated and consolidated.
988 Fixed segfault when unmounting read-only WIM.
991 Support for joining and splitting WIMs.
992 Also, security data is now preserved by default.
995 Can now build with older gcc and system headers, like on CentOS 5.
998 Fixed bug that made it impossible to overwrite files in read-write
1002 Write byte-order mark before WIM XML data. (imagex.exe requires this to
