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 Non UTF-8 locales are now detected correctly.
15 Some Windows-specific updates:
16 Fixed a bug where duplicate backslashes could be generated in
17 link targets when extracting symbolic links and junctions.
19 Fixed a bug where the .cmd shortcuts for wimlib-imagex would not
20 work if their full path contained a space.
22 Fixed bugs when capturing a WIM image from a SMB filesystem.
24 Added warning message about known issue with WindowsApps folder.
26 Added instructions for building from source on Windows.
28 VSS support is no longer marked "experimental".
30 Added missing license file for libdivsufsort-lite.
33 Added experimental support for Windows VSS (Volume Shadow Copy Service).
34 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
35 create and use a temporary VSS snapshot when capturing a WIM image.
37 Implemented setting of Windows-specific XML information, such as
38 architecture, system root, and version details. This information is now
39 automatically set in newly captured WIM images, when appropriate.
41 Improved performance of directory tree scans on Windows.
43 On Windows, to improve capture performance, wimlib now sometimes opens
44 files by inode number rather than by path. This is enabled for
45 wimcapture and wimappend, but for now other applications have to opt-in.
47 The progress messages printed by wimlib-imagex while writing WIM files
48 have been slightly tweaked.
50 Progress information for directory tree scans now counts all hard links.
51 Also, on Windows "\\?\" is no longer stripped from the current path.
53 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
54 'wiminfo'. This option lets you assign values to elements in a WIM
55 file's XML document by name.
57 The wimlib_get_image_property() and wimlib_set_image_property() API
58 functions now support numerically indexed elements.
60 Fixed a bug where, on Windows, wimlib would change the security
61 descriptor of the target directory of an extraction even when the
62 '--no-acls' option was specified.
65 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
66 some Microsoft software would not correctly recognize data in the
69 Made some small improvements to the compression algorithms:
70 LZX compression ratio was slightly improved.
71 XPRESS compression ratio and speed was slightly improved.
72 LZMS compression speed was slightly improved.
74 Improved handling of WIM XML data. wimlib no longer drops unrecognized
75 elements when exporting images. In addition, two API functions were
76 added for better access to elements in the XML document:
77 wimlib_get_image_property() and wimlib_set_image_property().
79 Added support for (unsafe) in-place compaction of WIM files.
81 Improved performance of image export by reusing metadata resources
82 instead of always rebuilding and recompressing them.
84 Improved performance of wimlib_update_image() by delaying the update to
85 the WIM's XML document until a write is requested.
87 On Windows, the target of an extraction may now be a reparse point
88 (which will be dereferenced).
90 On Windows, wimlib now correctly restores non-Microsoft reparse points.
91 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
93 On Windows, wimlib now has improved performance when archiving files
94 from a filesystem backed by a WIM (a "WIMBoot" setup).
96 Several improvements to System Compression (compact mode) support:
98 wof.sys (or wofadk.sys) is now automatically attached to the
99 target volume if needed.
101 Compact-mode extractions now work correctly with wofadk.sys on
102 older versions of Windows.
104 For compatibility with the Windows bootloader, the requested
105 compression format now is overridden on certain files.
107 Other minor bugfixes.
110 This release primarily contains various minor bug fixes and
111 improvements, including:
113 Improved handling of deep directory structures.
115 Fixed a bug where on 32-bit systems, the library could enter an
116 infinite loop if a WIM file was malformed in a specific way.
118 Added a workaround for a case where libntfs-3g may report
119 duplicate streams in an NTFS file.
121 Windows symbolic links and junctions in mounted WIM images are
122 now automatically rewritten to be valid in the mounted location.
124 Reparse point fixes: correctly handle the "ReparseReserved"
125 field, and correctly handle "empty" (data-less) reparse points.
127 On Windows, wimlib now acquires SeManageVolumePrivilege, which
128 is needed to create externally backed files using the
131 Improved validation of filenames.
133 Improved LZMS decompression speed.
135 The configure script now honors alternate pkg-config settings.
137 Links have been updated to point to the new website.
139 In addition, experimental support has been added for compressing
140 extracted files using System Compression on Windows 10. This
141 functionality is available through the new '--compact' option to
142 'wimapply' and 'wimextract' as well as new library flags.
145 Fixed a bug in the LZX decompressor: malicious input data could cause
146 out of bounds writes to memory (since wimlib v1.2.2).
148 The output of the 'wiminfo' command now consolidates various boolean
149 flags (such as "Relative path junction") into a single line.
151 A file can now have both an unnamed data stream ("file contents") and a
152 reparse point stream. Such files can exist as a result of the use of
153 certain Windows features, such as offline storage, including "OneDrive".
154 wimlib will now store and restore both streams on Windows as well as in
155 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
157 On Windows, named data streams of encrypted files are no longer stored
158 twice in WIM archives.
160 On Windows, named data streams are now correctly extracted to existing
161 "readonly" directories. Before, an error would be reported.
163 On Windows, it is now possible to do a "WIMBoot mode" extraction with
164 non-standalone WIMs such as delta WIMs.
166 On Windows, when doing an extraction in "WIMBoot mode", files larger
167 than 4 gigabytes are now never extracted as externally backed. This
168 works around a bug in Microsoft's "WOF" driver.
170 The '--enable-verify-compression' configure option has been removed. If
171 you want to verify a WIM file, use the 'wimverify' program.
173 The way the "file count", "directory count", "total bytes", and "hard
174 link bytes" image statistics (stored in the WIM XML data) is calculated
175 has been slightly changed.
177 In mounted WIM images, the disk usage provided for each file (st_blocks)
178 is now the compressed size rather than the uncompressed size.
180 The performance of the NTFS-3g and Windows capture modes has been
183 On UNIX-like systems, symbolic links whose targets contain the backslash
184 character are now handled correctly (losslessly).
187 Improved the LZX compressor. It is now 15-20% faster than before and
188 provides a slightly better compression ratio.
190 Improved the LZMS compressor. It now provides a compression ratio
191 slightly better than WIMGAPI while still being faster and using slightly
194 The compression chunk size in solid resources, e.g. when capturing or
195 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
196 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
197 better compression ratio and is the same value that WIMGAPI uses. The
198 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
199 lower than WIMGAPI's memory usage, but if it is too much, it is still
200 possible to choose a lower value, e.g. with the '--solid-chunk-size'
201 option to wimlib-imagex.
203 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
204 accept the 'K', 'M', and 'G' suffixes.
206 Files are now sorted by name extension when creating a solid WIM file.
208 Fixed various issues related to capture/apply of EFS-encrypted files on
211 The file list printed by 'wimdir' is now sorted by the platform-specific
212 case sensitivity setting, rather than always case sensitively. This
213 also affects the library function wimlib_iterate_dir_tree().
215 On Windows, some error and warning messages have been improved.
218 The Windows binary distribution no longer contains third party DLLs.
219 These dependencies are instead compiled directly into the libwim DLL.
221 Added more fixes for wimlib on non-x86 architectures such as ARM.
223 Extracting files to a Windows PE in-memory filesystem no longer fails if
224 the target files do not yet exist.
226 Improved the performance of XPRESS compression and LZMS decompression.
228 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
229 It will automatically be faster on newer Intel and AMD processors.
231 Removed the --with-imagex-progname and --enable-more-assertions
235 Fix for very slow export from solid WIM / ESD files.
237 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
239 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
240 may use this to treat some types of errors as non-fatal.
242 The library now permits making in-memory changes to a WIMStruct backed
243 by a read-only WIM file.
245 Fixes for "WIMBoot" extraction mode (Windows only):
247 When not using the WOF driver, extraction no longer fails if the
248 disk containing the WIM file has too many partitions.
250 When matching patterns in [PrepopulateList], all hard links of
251 each file are now considered.
253 The system registry files are now automatically treated as being
254 in [PrepopulateList].
256 Added a hack to try to work around an intermittent bug in
257 Microsoft's WOF (Windows Overlay Filesystem) driver.
260 Made more improvements to the XPRESS, LZX, and LZMS compressors.
262 A number of improvements to the Windows port:
264 Fixes for setting short filenames.
266 Faster "WIMBoot" extraction.
268 Updated and slimmed down the dependent DLLs.
270 ACL inheritence bits are now restored.
272 Mandatory integrity labels are now backed up and restored.
274 Added a workaround for an issue where in rare cases, wimlib could create
275 a compressed data stream that could not be read correctly by Windows
276 after an extraction in "WIMBoot" mode.
279 Added file count progress data for
280 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
281 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
283 Added support for testing file exclusions via the user-provided
286 Some documentation improvements.
288 Made some clarifications to the license text in the COPYING file.
291 Made more improvements to the XPRESS, LZX, and LZMS compressors.
293 The default compression mode for wimcapture is now LZX compression in
294 its default mode, which is the same as '--compress=maximum'.
296 You can now specify an optional integer compression level to the
297 '--compress' option; e.g. '--compress=lzx:75'.
299 Made a minor change to the LZMS compressor and decompressor to fix an
300 incompatibility with the Microsoft implementation. In the unlikely
301 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
302 earlier and a checksum error is reported when extracting files from it
303 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
306 Added 'verify' subcommand to wimlib-imagex.
308 Notable library changes:
310 Custom compressor parameters have been removed from the library
311 in favor of the simpler level-based API.
313 Decompressor parameters have been removed entirely.
315 Library users can now specify a custom file for warning and
316 error messages to be sent to, rather than the default of
319 New progress messages:
320 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
321 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
323 New function: wimlib_verify_wim().
326 Improved compression, decompression, and extraction performance.
328 Improved compatibility with version 3584 WIM / ESD files:
329 - Add support for reading and writing multiple solid blocks per
330 archive, which WIMGAPI/DISM can create when appending an image.
331 - Correctly create solid blocks larger than 4 GiB.
333 'add' commands passed to wimupdate will now replace existing
334 nondirectory files by default. Use the --no-replace option to get the
337 The license for the library now contains an exception that allows using
338 it under the LGPL. See the COPYING file for details.
340 In reparse-point fixup mode (the default for capture), symbolic links
341 and junctions that point outside the tree being captured are no longer
342 excluded from capture.
344 Added support for "WIMBoot" capture and extraction. See the
345 documentation for the new '--wimboot' option to wimcapture and wimapply
346 for more information.
348 On UNIX-like systems, you can now backup and restore device nodes, named
349 pipes, and sockets. In addition, 32-bit user and group IDs are now
352 The way that UNIX data is stored in WIM files has been changed. If you
353 captured any WIMs with the --unix-data option, to upgrade them you'll
354 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
355 re-capture them with --unix-data using this version.
357 wimlib now understands tagged metadata items, such as object IDs, that
358 can be stored in WIM directory entries.
360 Removed the --hardlink and --symlink options to wimapply, since I don't
361 think they are too useful and they got in the way of improving the code.
363 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
365 The 'mkwinpeimg' script now supports writing the ISO image to standard
368 The <ARCH> element in WIM XML data is now exported correctly.
370 On Windows, sparse file attributes are no longer set on extracted files.
371 Oddly enough, this actually saves disk space in some cases.
373 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
374 supported. Mounting WIM images now always requires extended attribute
375 support. Use --without-fuse to disable support for mounting WIM images;
376 this will also disable the need for extended attribute support.
378 Configuring with --enable-ssse3-sha1 now works correctly.
380 The shared library version has been bumped up. The main
381 incompatibilities are:
383 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
384 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
387 - User-provided progress functions are now registered using a
388 separate function, wimlib_register_progress_function(). The
389 'progress_func' argument to many functions no longer exists.
391 - The return value from user-provided progress functions is now
394 - A context argument has been added to the prototype of
395 user-provided progress functions.
397 - 'struct wimlib_capture_config' has been removed. The library
398 now takes the path to the configuration file directly. This
399 affects wimlib_add_image(), wimlib_add_image_multisource(),
400 and wimlib_update_image(). However, a NULL value passed in
401 the argument retains the same meaning.
403 - Removed deprecated functions: some (de)compression functions,
404 wimlib_extract_files(), and wimlib_print_metadata().
406 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
407 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
408 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
410 - Removed some progress messages:
411 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
412 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
413 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
416 - Removed some error codes. Numbering stays the same.
418 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
419 WIMLIB_UNMOUNT_FLAG_FORCE.
421 - WIM paths passed to progress functions now have a leading
425 Case-insensitive comparisons of strings (e.g. filenames) containing
426 UTF-16 codepoints above 32767 are now done correctly.
428 Fixed build failure on Mac OS X.
430 wimunmount now provides the '--new-image' option to cause changes to a
431 read-write mounted image to be committed as a new image rather than as
432 an update of the mounted image. (The corresponding new library flag is
433 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
435 The LZMS ("recovery") compression chunk size, or "dictionary size", may
436 now be up to 1 GiB (1,073,741,824 bytes).
438 The performance of LZX ("maximum") and LZMS ("recovery") compression
439 with large chunk sizes has been slightly improved.
442 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
443 decompressed correctly.
445 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
446 occurred in an unlikely case, and due to validity checks it did not
447 affect successfully created archives.
449 Fixed a minor compatibility issue with the LZMS compressor and
450 decompressor. This is *not* the default compression type and was only
451 introduced in v1.6.0. In the unlikely event that you created an
452 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
453 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
456 Memory usage for LZMS and LZX compression has been decreased.
458 wimextract now allows wildcard characters in paths specified on the
459 command line. Also, the '--strict-wildcards' option has been removed
460 and replaced with the inverse option '--nullglob'. See the
461 documentation for wimextract for more details and changes.
463 The wimlib_extract_files() function is now considered deprecated in
464 favor of wimlib_extract_paths().
466 Fixed more permissions problems when extracting files on Windows.
468 A new '--no-attributes' option has been added to wimapply and
469 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
471 The default chunk size is now set correctly when changing the
472 compression type of a WIM, for example with 'wimoptimize'.
474 The '--metadata' option to wiminfo has been replaced with the
475 '--detailed' option to wimdir.
477 In relevant wimlib-imagex commands, '--solid' may now be used as an
478 alias for '--pack-streams'.
481 Support for extracting and updating the new version 3584 WIMs has been
482 added. These WIMs typically pack many streams ("files") together into a
483 single compressed resource, thereby saving space. This degrades the
484 performance of random access (such as that which occurs on a mounted
485 image), but optimizations have been implemented for extraction. These
486 new WIM files also typically use a new compression format (LZMS), which
487 is similar to LZMA and can offer a better compression ratio than LZX.
488 These new WIM files can be created using `wimcapture' with
489 the '--compress=lzms --pack-streams' options. Note: this new WIM format
490 is used by the Windows 8 web downloader, but important segments of the
491 raw '.esd' files are encrypted, so wimlib will not be able to extract
492 such files until they are first decrypted.
494 wimlib now supports extracting files and directories from a WIM image
495 based on a "listfile" that itself contains the list of paths to extract.
496 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
497 and for the library itself, the new APIs are wimlib_extract_pathlist()
498 and wimlib_extract_paths(). Path globs containing wildcard characters
501 For searching WIM files, wimlib now has configurable case sensitivity.
502 The default on Windows is still case-insensitive and the default on
503 UNIX-like systems is still case-sensitive, but this can be overridden
504 on either platform through flags to wimlib_global_init(). For
505 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
506 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
509 Support for compression chunk sizes greater than the default of 32768
510 bytes has been added. A larger chunk size typically results in a better
511 compression ratio. However, the MS implementation is seemingly not
512 compatible with all chunk sizes, especially for LZX compression, so the
513 defaults remain unchanged, with the exception of the new LZMS-compressed
514 WIMs, which use a larger chunk size by default.
516 The compression/decompression API exported by wimlib has been changed.
517 Now one set of functions handles all supported compression formats.
519 `wimcapture' and `wimappend' will now display the progress of scanning
520 the directory tree to capture, in addition to the progress of writing
521 data to the WIM. The '--verbose' option no longer does anything. The
522 library API change for this is the addition of several members to
523 `struct wimlib_progress_info_scan' available to progress callbacks.
525 `mkwinpeimg' now correctly handles the '--start-script' option when the
526 start script is not in the working directory.
528 Sequential extraction, previously requested by using
529 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
530 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
531 behavior (extract in file order).
534 The new LZX compressor added in v1.5.2 has been improved and is now
535 enabled by default, except when `wimcapture' or `wimappend' is run
536 *without* the '--compress' option, in which case the faster LZX
537 compressor is used (the same as before). This behavior is reasonably
538 consistent with ImageX which actually uses "fast" (XPRESS) compression
539 by default. In those cases, use '--compress=maximum' to explicitly
540 capture a WIM image using the new (slower but better) LZX compressor.
542 The '--compress-slow' option still exists to `wimlib-imagex optimize',
543 but its new behavior is to tweak the new LZX compressor even more to
544 produce an even better compression ratio at the cost of more time spent
547 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
548 which recompresses the WIM file using the specified compression TYPE.
549 The new library API function used for this is
550 wimlib_set_output_compression_type().
552 Added the wimlib_get_xml_data() function to allow library clients to
553 easily retrieve the raw XML data from a WIM file if needed.
555 Fixed a bug that could cause an error code to be incorrectly returned
556 when writing XML data containing a <WINDOWS> element.
558 Mounted WIM images will now correctly show the default file stream even
559 if appears in the alternate data stream entries of the corresponding WIM
563 Added a new experimental LZX compressor which can be enabled by passing
564 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
565 optimize'. (The latter is only applicable if the WIM is already
566 LZX-compressed and the '--recompress' option is also given.) The
567 experimental compressor is much slower but compresses the data slightly
568 more --- currently usually to within a fraction of a percent of the
569 results from WIMGAPI/ImageX.
571 A workaround has been added for compatibility with versions of WinPE
572 that interpret alternate data stream entries in the boot WIM
575 An alignment bug that caused a crash in the LZX decompressor on some
578 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
579 the WIM header when restoring the previous state of a WIM it failed to
582 Added a workaround to avoid an access denied error on Windows when
583 replacing a WIM file that another process has opened.
586 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
587 needed to be handled.
589 A bug in the interpretation of negative IMAGE indices in the
590 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
591 `wimlib-imagex append' has been fixed.
593 A workaround has been added to successfully apply security descriptors
594 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
595 2013.1.13 or earlier.
597 `wimlib-imagex capture' can now accept the '--delta-from' option
601 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
602 to standard output and applying images from standard input, but they are
603 not compatible with Microsoft's software and are not created by default.
604 See the documentation for --pipable flag of `wimlib-imagex capture' for
607 To better support incremental backups, added support for declaring an
608 image as a modified form of another image. See the documentation for
609 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
612 Added supported for "delta" WIMs. See the documentation for the
613 '--delta-from' option of `wimlib-imagex capture'.
615 The library support for managing split WIMs has been changed to support
616 other arrangements, such as delta WIMs, and be easier to use. This
617 change is visible in `wimlib-imagex', which also can now accept the
618 '--ref' option multiple times, and also now supports "delta" WIMs as
621 wimlib now preserves WIM integrity tables by default, even if
622 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
623 behavior of `wimlib-imagex' whenever the WIM being operated on contains
624 an integrity table and the '--check' option is not specified.
626 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
627 (when --compress is not specified). This provides the best compression
628 ratio by default, which is usually what is desired, at a cost of some
631 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
632 is the command as in `wimlib-imagex COMMAND'; for example, it can be
633 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
634 appropriate hard links are created in UNIX installations of
635 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
636 batch files that emulate this behavior are generated.
638 Security descriptors are now extracted correctly on Windows.
640 Fixed archiving DOS names in NTFS-3g capture mode.
642 The extraction code has been rewritten and it will now be easier to
643 support new features on all supported backends (currently Win32, UNIX,
644 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
645 now supported on all backends, not just UNIX.
647 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
648 than the WAIK itself.
650 wimlib_global_init() now, by default, attempts to acquire additional
651 privileges on Windows, so library clients need not do this.
653 This update bumps the shared library version number up to 9, since it is
654 not binary compatibible with previous releases.
657 Fixed bug in `wimlib-imagex export' that made it impossible to export an
658 image from a WIM that is readonly at the filesystem level.
660 Return error code rather than segfaulting when trying to list files from
661 a non-first part of a split WIM.
663 Joining a WIM will now preserve the RP_FIX and READONLY flags.
666 On Windows, paths given to wimlib-imagex are now treated case
669 Improved behavior regarding invalid filenames; in particular, on
670 Windows, wimlib-imagex will, when extracting, now omit (with an option
671 to override this default) filenames differing only in case, or filenames
672 containing characters not valid on Windows.
674 On Windows, wimlib now supports capturing and extracting long paths
675 (longer than the so-called MAX_PATH).
677 On Windows, `wimlib-imagex update' now acquires proper privileges when
678 running as an Administrator.
680 `wimlib-imagex update' will now complain if no image is specified when
681 trying to update a multi-image WIM.
683 `wimlib-imagex update' now supports specifying a single update command
684 directly on the command line using the --command option.
686 wimlib-imagex will now choose different units for progress messages,
687 depending on the amount of data that needs to be processed.
689 `wimlib-imagex append' will now generate a unique WIM image name if no
690 name is specified and the defaulted name already exists in the WIM.
692 wimlib now allows you to create unnamed WIM images, which can then only
693 be referred to by index.
695 wimlib now allows you to explicitly declare you want write access to a
696 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
699 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
702 Progress callbacks have been added to wimlib's wimlib_update_image()
705 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
706 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
709 NTFS-3g capture now only warns about two conditions previously treated
712 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
715 wimlib now correctly detects and returns an error when reading a WIM
716 image with a cyclic directory structure. (Fun fact: such a WIM will
717 crash Microsoft's software.)
720 Added new "extract" and "update" subcommands to wimlib-imagex, along
721 with associated APIs in the library. These commands are intended mainly
722 for Windows use but can be used on UNIX as well.
724 Many documentation improvements.
726 Fixed a bug in the Windows build where relative symbolic links were not
727 captured in reparse-point fixup mode.
729 Fixed a bug in the Windows build where file handles were left open to
730 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
732 Fixed a bug in the Windows build of wimlib-imagex where globbing
733 split-WIM parts could cause the program to crash.
735 Fixed a bug where the creation time of WIM images would be shown instead
736 of the last modification time.
738 With the Windows build it is now possible to restore a WIM containing
739 symbolic links as a non-Administrator; however you will receive warnings
740 about not being able to extract the symbolic links.
743 Capturing a WIM image should now be significantly faster in most cases
744 due to improved use of the operating system's cache and avoiding reading
745 files twice whenever possible.
747 The Windows build should now work on Windows XP.
749 The Windows build now supports capturing and restoring hidden,
750 compressed, sparse, and encrypted files.
752 The Windows build now supports capturing and applying WIM images from
753 filesystems other than NTFS (with some reduced functionality).
755 The Windows build now extracts short names correctly.
757 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
758 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
759 capture' and `wimlib-imagex apply'.
761 The performance of splitting and joining WIMs should be slightly
764 The LZX and XPRESS compression and decompression functions are now
765 exported from the library.
768 Improvements and bugfixes for the Windows build.
770 Added --strict-acls options.
772 Fixed the way that wimlib determines the order of images in the WIM.
775 Since wimlib can now be used on Windows, wimlib's implementation of
776 ImageX has been renamed to wimlib-imagex to avoid confusion with
777 Microsoft's implementation of ImageX, which would have the same file
778 name ("imagex.exe"). If you really don't like this you can pass the
779 --with-imagex-progname option to `configure' to choose a different name,
780 or even simply rename the binary yourself (but the former way will
781 configure the man pages to use the chosen name).
783 Various bugs fixed in the Windows build. Mainly to do with capturing
784 and restoring alternate data streams correctly in weird cases, and
785 requesting the correct privileges when opening files. Also added the
786 --noacls options to wimlib-imagex capture, append, and apply.
788 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
789 dynamically loaded, so this may make the library compatible with Windows
790 XP (however, there may still be other problems).
793 Added experimental support for native Windows builds. Binaries can be
794 downloaded from the SourceForge page.
796 --source-list option added to `imagex capture' and `imagex append'.
798 Better support for different character encodings.
801 Storing UNIX file owners, groups, and modes in WIM images is now
802 possible using `imagex capture' with the --unix-data flag.
804 Minor bug fixes and documentation fixes.
807 NTFS capture: Fixed capturing duplicate reparse points.
809 NTFS capture: Capture first unnamed stream if there are more than one
810 (print warning instead of error).
812 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
815 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
818 Update to work with ntfs-3g version 2013.1.13.
821 Fixed truncating file to shorter but non-zero length on read-write
824 Various code cleanups and minor documentation fixes.
827 LZX and XPRESS decompression have received some additional optimizations
828 and should now be even faster. (Although, they were already pretty
829 fast--- much faster than typical I/O speeds.)
831 Fixed a bug introduced in v1.2.1 that would cause a directory tree
832 containing hard links to be captured incorrectly in some cases.
835 By default, unmounting a read-write mounted WIM with 'imagex unmount
836 --commit' will now change the WIM in-place without needing to write the
837 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
840 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
841 for a response from the daemon servicing the mounted WIM. Instead,
842 every second 'imagex unmount' will check if the daemon is still alive,
843 and keep waiting if so, otherwise terminate with an error.
845 'imagex unmount --commit' on a read-write mounted WIM will now print
846 progress information regarding the writing of new or modified streams
847 the WIM, just like when capturing or appending a WIM.
849 A small change has been made to XPRESS compression and it should improve
850 the compression ratio slightly.
852 A change was made that may improve performance slightly when applying a
853 WIM image to a NTFS volume.
855 Microsoft has managed to introduce even more bugs into their software,
856 and now the WIMs for Windows 8 have incorrect (too low) reference counts
857 for some streams. This is unsafe because such streams can be removed
858 when they are in actuality still referenced in the WIM (perhaps by a
859 different image). wimlib will now work around this problem by fixing
860 the stream reference counts. This is only done when wimlib_delete_image() is
861 called ('imagex delete') or when wimlib_mount_image() is called with
862 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
863 requires reading the metadata for all images in the WIM, so this will
864 make these operations noticably slower on WIMs with multiple images.
866 Various other bugfixes.
869 Appending images to a WIM is now be done by default without re-building
870 the whole WIM. Use the --rebuild flag to get the old behavior (which
871 was to re-build the entire WIM when a new image is appended).
873 A new command `imagex optimize' is now available to manually re-build a
874 WIM that has wasted space due to repeated appends.
876 Progress information has been improved, and now arbitrary callback
877 functions can be used to show the progress of a WIM operation.
879 A possible bug with changing the bootable image of a WIM was fixed.
881 Some advisory locking is now done to prevent two processes from
882 modifying a WIM at the same time (but only in some cases). For example,
883 you cannot mount two images from a WIM read-write at the same time.
885 Some functions have been reorganized:
886 * wimlib_mount() renamed to wimlib_mount_image().
887 * wimlib_unmount() renamed to wimlib_unmount_image().
888 * wimlib_overwrite_xml_and_header() removed as
889 wimlib_overwrite() suffices now.
890 * wimlib_apply_image_to_ntfs_volume() removed as
891 wimlib_extract_image() suffices now.
892 * wimlib_add_image_from_ntfs_volume() removed as
893 * wimlib_add_image() suffices now.
895 Previously, the soname of libwim.so has been 0.0.0, despite many
896 interface changes. The soname is now updated to 1.0.0 and will now be
897 updated each release.
900 Resources will now be compressed using multiple threads by default.
901 (This applies to `imagex capture', `imagex append', and `imagex
904 Some performance improvements in mounted WIMs.
906 More progress information is shown when capturing a WIM.
909 Lots of minor fixes, code cleanups, and some documentation updates.
910 Nothing in particular is really noteworthy.
913 LZX and XPRESS compression improvements.
915 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
916 Link Bytes of the WIM.
919 Fixed bug when capturing NTFS file with multiple named data streams.
921 Internally, we are now using inode structures, even though these don't
922 appear literally in the WIM file. This simplifies some of the code
923 (mainly for WIM mounting) and likely fixed a few problems, although it
927 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
931 Enough changes to call it version 1.0.0!
933 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
934 to a NTFS volume, is now supported.
936 Hard links and symbolic links have much improved support. They are
937 supported for WIM capture, WIM application, and mounted WIMs (you can
938 even make them on read-write mounted WIMs).
940 Alternate data streams are now supported on mounted WIMs through an
941 xattr or a Windows-style stream interface. Also they are supported when
942 capturing a WIM from NTFS or applying a WIM to NTFS.
944 Split WIMs are better supported. You may now apply an image directly
945 from a split WIM, mount an image from a split WIM read-only, or export
946 an image from a split WIM.
948 Using a capture configuration file is now supported (but not fully yet).
950 SHA1 message digests are checked in more places, so we can make sure
951 applied and captured data is correct.
953 Man pages have been updated and consolidated.
956 Fixed segfault when unmounting read-only WIM.
959 Support for joining and splitting WIMs.
960 Also, security data is now preserved by default.
963 Can now build with older gcc and system headers, like on CentOS 5.
966 Fixed bug that made it impossible to overwrite files in read-write
970 Write byte-order mark before WIM XML data. (imagex.exe requires this to
