2 Added support for object IDs, which are a type of metadata sometimes
3 present on NTFS filesystems. They are used by some Windows software,
4 such as the Distributed Link Tracking Service. Object IDs are now
5 captured and applied both in NTFS-3g mode and on Windows when supported
8 Reduced memory usage when exporting large numbers of WIM images.
10 Made some minor build-related updates. Notably, enabled "silent" make
11 rules; this makes the output cleaner when building from source.
13 Some Windows-specific updates:
14 Fixed a bug where duplicate backslashes could be generated in
15 link targets when extracting symbolic links and junctions.
17 Fixed a bug where the .cmd shortcuts for wimlib-imagex would not
18 work if their full path contained a space.
20 Fixed bugs when capturing a WIM image from a SMB filesystem.
22 Added warning message about known issue with WindowsApps folder.
24 Added instructions for building from source on Windows.
26 VSS support is no longer marked "experimental".
29 Added experimental support for Windows VSS (Volume Shadow Copy Service).
30 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
31 create and use a temporary VSS snapshot when capturing a WIM image.
33 Implemented setting of Windows-specific XML information, such as
34 architecture, system root, and version details. This information is now
35 automatically set in newly captured WIM images, when appropriate.
37 Improved performance of directory tree scans on Windows.
39 On Windows, to improve capture performance, wimlib now sometimes opens
40 files by inode number rather than by path. This is enabled for
41 wimcapture and wimappend, but for now other applications have to opt-in.
43 The progress messages printed by wimlib-imagex while writing WIM files
44 have been slightly tweaked.
46 Progress information for directory tree scans now counts all hard links.
47 Also, on Windows "\\?\" is no longer stripped from the current path.
49 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
50 'wiminfo'. This option lets you assign values to elements in a WIM
51 file's XML document by name.
53 The wimlib_get_image_property() and wimlib_set_image_property() API
54 functions now support numerically indexed elements.
56 Fixed a bug where, on Windows, wimlib would change the security
57 descriptor of the target directory of an extraction even when the
58 '--no-acls' option was specified.
61 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
62 some Microsoft software would not correctly recognize data in the
65 Made some small improvements to the compression algorithms:
66 LZX compression ratio was slightly improved.
67 XPRESS compression ratio and speed was slightly improved.
68 LZMS compression speed was slightly improved.
70 Improved handling of WIM XML data. wimlib no longer drops unrecognized
71 elements when exporting images. In addition, two API functions were
72 added for better access to elements in the XML document:
73 wimlib_get_image_property() and wimlib_set_image_property().
75 Added support for (unsafe) in-place compaction of WIM files.
77 Improved performance of image export by reusing metadata resources
78 instead of always rebuilding and recompressing them.
80 Improved performance of wimlib_update_image() by delaying the update to
81 the WIM's XML document until a write is requested.
83 On Windows, the target of an extraction may now be a reparse point
84 (which will be dereferenced).
86 On Windows, wimlib now correctly restores non-Microsoft reparse points.
87 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
89 On Windows, wimlib now has improved performance when archiving files
90 from a filesystem backed by a WIM (a "WIMBoot" setup).
92 Several improvements to System Compression (compact mode) support:
94 wof.sys (or wofadk.sys) is now automatically attached to the
95 target volume if needed.
97 Compact-mode extractions now work correctly with wofadk.sys on
98 older versions of Windows.
100 For compatibility with the Windows bootloader, the requested
101 compression format now is overridden on certain files.
103 Other minor bugfixes.
106 This release primarily contains various minor bug fixes and
107 improvements, including:
109 Improved handling of deep directory structures.
111 Fixed a bug where on 32-bit systems, the library could enter an
112 infinite loop if a WIM file was malformed in a specific way.
114 Added a workaround for a case where libntfs-3g may report
115 duplicate streams in an NTFS file.
117 Windows symbolic links and junctions in mounted WIM images are
118 now automatically rewritten to be valid in the mounted location.
120 Reparse point fixes: correctly handle the "ReparseReserved"
121 field, and correctly handle "empty" (data-less) reparse points.
123 On Windows, wimlib now acquires SeManageVolumePrivilege, which
124 is needed to create externally backed files using the
127 Improved validation of filenames.
129 Improved LZMS decompression speed.
131 The configure script now honors alternate pkg-config settings.
133 Links have been updated to point to the new website.
135 In addition, experimental support has been added for compressing
136 extracted files using System Compression on Windows 10. This
137 functionality is available through the new '--compact' option to
138 'wimapply' and 'wimextract' as well as new library flags.
141 Fixed a bug in the LZX decompressor: malicious input data could cause
142 out of bounds writes to memory (since wimlib v1.2.2).
144 The output of the 'wiminfo' command now consolidates various boolean
145 flags (such as "Relative path junction") into a single line.
147 A file can now have both an unnamed data stream ("file contents") and a
148 reparse point stream. Such files can exist as a result of the use of
149 certain Windows features, such as offline storage, including "OneDrive".
150 wimlib will now store and restore both streams on Windows as well as in
151 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
153 On Windows, named data streams of encrypted files are no longer stored
154 twice in WIM archives.
156 On Windows, named data streams are now correctly extracted to existing
157 "readonly" directories. Before, an error would be reported.
159 On Windows, it is now possible to do a "WIMBoot mode" extraction with
160 non-standalone WIMs such as delta WIMs.
162 On Windows, when doing an extraction in "WIMBoot mode", files larger
163 than 4 gigabytes are now never extracted as externally backed. This
164 works around a bug in Microsoft's "WOF" driver.
166 The '--enable-verify-compression' configure option has been removed. If
167 you want to verify a WIM file, use the 'wimverify' program.
169 The way the "file count", "directory count", "total bytes", and "hard
170 link bytes" image statistics (stored in the WIM XML data) is calculated
171 has been slightly changed.
173 In mounted WIM images, the disk usage provided for each file (st_blocks)
174 is now the compressed size rather than the uncompressed size.
176 The performance of the NTFS-3g and Windows capture modes has been
179 On UNIX-like systems, symbolic links whose targets contain the backslash
180 character are now handled correctly (losslessly).
183 Improved the LZX compressor. It is now 15-20% faster than before and
184 provides a slightly better compression ratio.
186 Improved the LZMS compressor. It now provides a compression ratio
187 slightly better than WIMGAPI while still being faster and using slightly
190 The compression chunk size in solid resources, e.g. when capturing or
191 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
192 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
193 better compression ratio and is the same value that WIMGAPI uses. The
194 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
195 lower than WIMGAPI's memory usage, but if it is too much, it is still
196 possible to choose a lower value, e.g. with the '--solid-chunk-size'
197 option to wimlib-imagex.
199 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
200 accept the 'K', 'M', and 'G' suffixes.
202 Files are now sorted by name extension when creating a solid WIM file.
204 Fixed various issues related to capture/apply of EFS-encrypted files on
207 The file list printed by 'wimdir' is now sorted by the platform-specific
208 case sensitivity setting, rather than always case sensitively. This
209 also affects the library function wimlib_iterate_dir_tree().
211 On Windows, some error and warning messages have been improved.
214 The Windows binary distribution no longer contains third party DLLs.
215 These dependencies are instead compiled directly into the libwim DLL.
217 Added more fixes for wimlib on non-x86 architectures such as ARM.
219 Extracting files to a Windows PE in-memory filesystem no longer fails if
220 the target files do not yet exist.
222 Improved the performance of XPRESS compression and LZMS decompression.
224 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
225 It will automatically be faster on newer Intel and AMD processors.
227 Removed the --with-imagex-progname and --enable-more-assertions
231 Fix for very slow export from solid WIM / ESD files.
233 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
235 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
236 may use this to treat some types of errors as non-fatal.
238 The library now permits making in-memory changes to a WIMStruct backed
239 by a read-only WIM file.
241 Fixes for "WIMBoot" extraction mode (Windows only):
243 When not using the WOF driver, extraction no longer fails if the
244 disk containing the WIM file has too many partitions.
246 When matching patterns in [PrepopulateList], all hard links of
247 each file are now considered.
249 The system registry files are now automatically treated as being
250 in [PrepopulateList].
252 Added a hack to try to work around an intermittent bug in
253 Microsoft's WOF (Windows Overlay Filesystem) driver.
256 Made more improvements to the XPRESS, LZX, and LZMS compressors.
258 A number of improvements to the Windows port:
260 Fixes for setting short filenames.
262 Faster "WIMBoot" extraction.
264 Updated and slimmed down the dependent DLLs.
266 ACL inheritence bits are now restored.
268 Mandatory integrity labels are now backed up and restored.
270 Added a workaround for an issue where in rare cases, wimlib could create
271 a compressed data stream that could not be read correctly by Windows
272 after an extraction in "WIMBoot" mode.
275 Added file count progress data for
276 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
277 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
279 Added support for testing file exclusions via the user-provided
282 Some documentation improvements.
284 Made some clarifications to the license text in the COPYING file.
287 Made more improvements to the XPRESS, LZX, and LZMS compressors.
289 The default compression mode for wimcapture is now LZX compression in
290 its default mode, which is the same as '--compress=maximum'.
292 You can now specify an optional integer compression level to the
293 '--compress' option; e.g. '--compress=lzx:75'.
295 Made a minor change to the LZMS compressor and decompressor to fix an
296 incompatibility with the Microsoft implementation. In the unlikely
297 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
298 earlier and a checksum error is reported when extracting files from it
299 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
302 Added 'verify' subcommand to wimlib-imagex.
304 Notable library changes:
306 Custom compressor parameters have been removed from the library
307 in favor of the simpler level-based API.
309 Decompressor parameters have been removed entirely.
311 Library users can now specify a custom file for warning and
312 error messages to be sent to, rather than the default of
315 New progress messages:
316 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
317 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
319 New function: wimlib_verify_wim().
322 Improved compression, decompression, and extraction performance.
324 Improved compatibility with version 3584 WIM / ESD files:
325 - Add support for reading and writing multiple solid blocks per
326 archive, which WIMGAPI/DISM can create when appending an image.
327 - Correctly create solid blocks larger than 4 GiB.
329 'add' commands passed to wimupdate will now replace existing
330 nondirectory files by default. Use the --no-replace option to get the
333 The license for the library now contains an exception that allows using
334 it under the LGPL. See the COPYING file for details.
336 In reparse-point fixup mode (the default for capture), symbolic links
337 and junctions that point outside the tree being captured are no longer
338 excluded from capture.
340 Added support for "WIMBoot" capture and extraction. See the
341 documentation for the new '--wimboot' option to wimcapture and wimapply
342 for more information.
344 On UNIX-like systems, you can now backup and restore device nodes, named
345 pipes, and sockets. In addition, 32-bit user and group IDs are now
348 The way that UNIX data is stored in WIM files has been changed. If you
349 captured any WIMs with the --unix-data option, to upgrade them you'll
350 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
351 re-capture them with --unix-data using this version.
353 wimlib now understands tagged metadata items, such as object IDs, that
354 can be stored in WIM directory entries.
356 Removed the --hardlink and --symlink options to wimapply, since I don't
357 think they are too useful and they got in the way of improving the code.
359 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
361 The 'mkwinpeimg' script now supports writing the ISO image to standard
364 The <ARCH> element in WIM XML data is now exported correctly.
366 On Windows, sparse file attributes are no longer set on extracted files.
367 Oddly enough, this actually saves disk space in some cases.
369 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
370 supported. Mounting WIM images now always requires extended attribute
371 support. Use --without-fuse to disable support for mounting WIM images;
372 this will also disable the need for extended attribute support.
374 Configuring with --enable-ssse3-sha1 now works correctly.
376 The shared library version has been bumped up. The main
377 incompatibilities are:
379 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
380 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
383 - User-provided progress functions are now registered using a
384 separate function, wimlib_register_progress_function(). The
385 'progress_func' argument to many functions no longer exists.
387 - The return value from user-provided progress functions is now
390 - A context argument has been added to the prototype of
391 user-provided progress functions.
393 - 'struct wimlib_capture_config' has been removed. The library
394 now takes the path to the configuration file directly. This
395 affects wimlib_add_image(), wimlib_add_image_multisource(),
396 and wimlib_update_image(). However, a NULL value passed in
397 the argument retains the same meaning.
399 - Removed deprecated functions: some (de)compression functions,
400 wimlib_extract_files(), and wimlib_print_metadata().
402 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
403 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
404 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
406 - Removed some progress messages:
407 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
408 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
409 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
412 - Removed some error codes. Numbering stays the same.
414 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
415 WIMLIB_UNMOUNT_FLAG_FORCE.
417 - WIM paths passed to progress functions now have a leading
421 Case-insensitive comparisons of strings (e.g. filenames) containing
422 UTF-16 codepoints above 32767 are now done correctly.
424 Fixed build failure on Mac OS X.
426 wimunmount now provides the '--new-image' option to cause changes to a
427 read-write mounted image to be committed as a new image rather than as
428 an update of the mounted image. (The corresponding new library flag is
429 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
431 The LZMS ("recovery") compression chunk size, or "dictionary size", may
432 now be up to 1 GiB (1,073,741,824 bytes).
434 The performance of LZX ("maximum") and LZMS ("recovery") compression
435 with large chunk sizes has been slightly improved.
438 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
439 decompressed correctly.
441 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
442 occurred in an unlikely case, and due to validity checks it did not
443 affect successfully created archives.
445 Fixed a minor compatibility issue with the LZMS compressor and
446 decompressor. This is *not* the default compression type and was only
447 introduced in v1.6.0. In the unlikely event that you created an
448 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
449 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
452 Memory usage for LZMS and LZX compression has been decreased.
454 wimextract now allows wildcard characters in paths specified on the
455 command line. Also, the '--strict-wildcards' option has been removed
456 and replaced with the inverse option '--nullglob'. See the
457 documentation for wimextract for more details and changes.
459 The wimlib_extract_files() function is now considered deprecated in
460 favor of wimlib_extract_paths().
462 Fixed more permissions problems when extracting files on Windows.
464 A new '--no-attributes' option has been added to wimapply and
465 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
467 The default chunk size is now set correctly when changing the
468 compression type of a WIM, for example with 'wimoptimize'.
470 The '--metadata' option to wiminfo has been replaced with the
471 '--detailed' option to wimdir.
473 In relevant wimlib-imagex commands, '--solid' may now be used as an
474 alias for '--pack-streams'.
477 Support for extracting and updating the new version 3584 WIMs has been
478 added. These WIMs typically pack many streams ("files") together into a
479 single compressed resource, thereby saving space. This degrades the
480 performance of random access (such as that which occurs on a mounted
481 image), but optimizations have been implemented for extraction. These
482 new WIM files also typically use a new compression format (LZMS), which
483 is similar to LZMA and can offer a better compression ratio than LZX.
484 These new WIM files can be created using `wimcapture' with
485 the '--compress=lzms --pack-streams' options. Note: this new WIM format
486 is used by the Windows 8 web downloader, but important segments of the
487 raw '.esd' files are encrypted, so wimlib will not be able to extract
488 such files until they are first decrypted.
490 wimlib now supports extracting files and directories from a WIM image
491 based on a "listfile" that itself contains the list of paths to extract.
492 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
493 and for the library itself, the new APIs are wimlib_extract_pathlist()
494 and wimlib_extract_paths(). Path globs containing wildcard characters
497 For searching WIM files, wimlib now has configurable case sensitivity.
498 The default on Windows is still case-insensitive and the default on
499 UNIX-like systems is still case-sensitive, but this can be overridden
500 on either platform through flags to wimlib_global_init(). For
501 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
502 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
505 Support for compression chunk sizes greater than the default of 32768
506 bytes has been added. A larger chunk size typically results in a better
507 compression ratio. However, the MS implementation is seemingly not
508 compatible with all chunk sizes, especially for LZX compression, so the
509 defaults remain unchanged, with the exception of the new LZMS-compressed
510 WIMs, which use a larger chunk size by default.
512 The compression/decompression API exported by wimlib has been changed.
513 Now one set of functions handles all supported compression formats.
515 `wimcapture' and `wimappend' will now display the progress of scanning
516 the directory tree to capture, in addition to the progress of writing
517 data to the WIM. The '--verbose' option no longer does anything. The
518 library API change for this is the addition of several members to
519 `struct wimlib_progress_info_scan' available to progress callbacks.
521 `mkwinpeimg' now correctly handles the '--start-script' option when the
522 start script is not in the working directory.
524 Sequential extraction, previously requested by using
525 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
526 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
527 behavior (extract in file order).
530 The new LZX compressor added in v1.5.2 has been improved and is now
531 enabled by default, except when `wimcapture' or `wimappend' is run
532 *without* the '--compress' option, in which case the faster LZX
533 compressor is used (the same as before). This behavior is reasonably
534 consistent with ImageX which actually uses "fast" (XPRESS) compression
535 by default. In those cases, use '--compress=maximum' to explicitly
536 capture a WIM image using the new (slower but better) LZX compressor.
538 The '--compress-slow' option still exists to `wimlib-imagex optimize',
539 but its new behavior is to tweak the new LZX compressor even more to
540 produce an even better compression ratio at the cost of more time spent
543 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
544 which recompresses the WIM file using the specified compression TYPE.
545 The new library API function used for this is
546 wimlib_set_output_compression_type().
548 Added the wimlib_get_xml_data() function to allow library clients to
549 easily retrieve the raw XML data from a WIM file if needed.
551 Fixed a bug that could cause an error code to be incorrectly returned
552 when writing XML data containing a <WINDOWS> element.
554 Mounted WIM images will now correctly show the default file stream even
555 if appears in the alternate data stream entries of the corresponding WIM
559 Added a new experimental LZX compressor which can be enabled by passing
560 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
561 optimize'. (The latter is only applicable if the WIM is already
562 LZX-compressed and the '--recompress' option is also given.) The
563 experimental compressor is much slower but compresses the data slightly
564 more --- currently usually to within a fraction of a percent of the
565 results from WIMGAPI/ImageX.
567 A workaround has been added for compatibility with versions of WinPE
568 that interpret alternate data stream entries in the boot WIM
571 An alignment bug that caused a crash in the LZX decompressor on some
574 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
575 the WIM header when restoring the previous state of a WIM it failed to
578 Added a workaround to avoid an access denied error on Windows when
579 replacing a WIM file that another process has opened.
582 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
583 needed to be handled.
585 A bug in the interpretation of negative IMAGE indices in the
586 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
587 `wimlib-imagex append' has been fixed.
589 A workaround has been added to successfully apply security descriptors
590 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
591 2013.1.13 or earlier.
593 `wimlib-imagex capture' can now accept the '--delta-from' option
597 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
598 to standard output and applying images from standard input, but they are
599 not compatible with Microsoft's software and are not created by default.
600 See the documentation for --pipable flag of `wimlib-imagex capture' for
603 To better support incremental backups, added support for declaring an
604 image as a modified form of another image. See the documentation for
605 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
608 Added supported for "delta" WIMs. See the documentation for the
609 '--delta-from' option of `wimlib-imagex capture'.
611 The library support for managing split WIMs has been changed to support
612 other arrangements, such as delta WIMs, and be easier to use. This
613 change is visible in `wimlib-imagex', which also can now accept the
614 '--ref' option multiple times, and also now supports "delta" WIMs as
617 wimlib now preserves WIM integrity tables by default, even if
618 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
619 behavior of `wimlib-imagex' whenever the WIM being operated on contains
620 an integrity table and the '--check' option is not specified.
622 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
623 (when --compress is not specified). This provides the best compression
624 ratio by default, which is usually what is desired, at a cost of some
627 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
628 is the command as in `wimlib-imagex COMMAND'; for example, it can be
629 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
630 appropriate hard links are created in UNIX installations of
631 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
632 batch files that emulate this behavior are generated.
634 Security descriptors are now extracted correctly on Windows.
636 Fixed archiving DOS names in NTFS-3g capture mode.
638 The extraction code has been rewritten and it will now be easier to
639 support new features on all supported backends (currently Win32, UNIX,
640 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
641 now supported on all backends, not just UNIX.
643 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
644 than the WAIK itself.
646 wimlib_global_init() now, by default, attempts to acquire additional
647 privileges on Windows, so library clients need not do this.
649 This update bumps the shared library version number up to 9, since it is
650 not binary compatibible with previous releases.
653 Fixed bug in `wimlib-imagex export' that made it impossible to export an
654 image from a WIM that is readonly at the filesystem level.
656 Return error code rather than segfaulting when trying to list files from
657 a non-first part of a split WIM.
659 Joining a WIM will now preserve the RP_FIX and READONLY flags.
662 On Windows, paths given to wimlib-imagex are now treated case
665 Improved behavior regarding invalid filenames; in particular, on
666 Windows, wimlib-imagex will, when extracting, now omit (with an option
667 to override this default) filenames differing only in case, or filenames
668 containing characters not valid on Windows.
670 On Windows, wimlib now supports capturing and extracting long paths
671 (longer than the so-called MAX_PATH).
673 On Windows, `wimlib-imagex update' now acquires proper privileges when
674 running as an Administrator.
676 `wimlib-imagex update' will now complain if no image is specified when
677 trying to update a multi-image WIM.
679 `wimlib-imagex update' now supports specifying a single update command
680 directly on the command line using the --command option.
682 wimlib-imagex will now choose different units for progress messages,
683 depending on the amount of data that needs to be processed.
685 `wimlib-imagex append' will now generate a unique WIM image name if no
686 name is specified and the defaulted name already exists in the WIM.
688 wimlib now allows you to create unnamed WIM images, which can then only
689 be referred to by index.
691 wimlib now allows you to explicitly declare you want write access to a
692 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
695 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
698 Progress callbacks have been added to wimlib's wimlib_update_image()
701 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
702 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
705 NTFS-3g capture now only warns about two conditions previously treated
708 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
711 wimlib now correctly detects and returns an error when reading a WIM
712 image with a cyclic directory structure. (Fun fact: such a WIM will
713 crash Microsoft's software.)
716 Added new "extract" and "update" subcommands to wimlib-imagex, along
717 with associated APIs in the library. These commands are intended mainly
718 for Windows use but can be used on UNIX as well.
720 Many documentation improvements.
722 Fixed a bug in the Windows build where relative symbolic links were not
723 captured in reparse-point fixup mode.
725 Fixed a bug in the Windows build where file handles were left open to
726 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
728 Fixed a bug in the Windows build of wimlib-imagex where globbing
729 split-WIM parts could cause the program to crash.
731 Fixed a bug where the creation time of WIM images would be shown instead
732 of the last modification time.
734 With the Windows build it is now possible to restore a WIM containing
735 symbolic links as a non-Administrator; however you will receive warnings
736 about not being able to extract the symbolic links.
739 Capturing a WIM image should now be significantly faster in most cases
740 due to improved use of the operating system's cache and avoiding reading
741 files twice whenever possible.
743 The Windows build should now work on Windows XP.
745 The Windows build now supports capturing and restoring hidden,
746 compressed, sparse, and encrypted files.
748 The Windows build now supports capturing and applying WIM images from
749 filesystems other than NTFS (with some reduced functionality).
751 The Windows build now extracts short names correctly.
753 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
754 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
755 capture' and `wimlib-imagex apply'.
757 The performance of splitting and joining WIMs should be slightly
760 The LZX and XPRESS compression and decompression functions are now
761 exported from the library.
764 Improvements and bugfixes for the Windows build.
766 Added --strict-acls options.
768 Fixed the way that wimlib determines the order of images in the WIM.
771 Since wimlib can now be used on Windows, wimlib's implementation of
772 ImageX has been renamed to wimlib-imagex to avoid confusion with
773 Microsoft's implementation of ImageX, which would have the same file
774 name ("imagex.exe"). If you really don't like this you can pass the
775 --with-imagex-progname option to `configure' to choose a different name,
776 or even simply rename the binary yourself (but the former way will
777 configure the man pages to use the chosen name).
779 Various bugs fixed in the Windows build. Mainly to do with capturing
780 and restoring alternate data streams correctly in weird cases, and
781 requesting the correct privileges when opening files. Also added the
782 --noacls options to wimlib-imagex capture, append, and apply.
784 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
785 dynamically loaded, so this may make the library compatible with Windows
786 XP (however, there may still be other problems).
789 Added experimental support for native Windows builds. Binaries can be
790 downloaded from the SourceForge page.
792 --source-list option added to `imagex capture' and `imagex append'.
794 Better support for different character encodings.
797 Storing UNIX file owners, groups, and modes in WIM images is now
798 possible using `imagex capture' with the --unix-data flag.
800 Minor bug fixes and documentation fixes.
803 NTFS capture: Fixed capturing duplicate reparse points.
805 NTFS capture: Capture first unnamed stream if there are more than one
806 (print warning instead of error).
808 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
811 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
814 Update to work with ntfs-3g version 2013.1.13.
817 Fixed truncating file to shorter but non-zero length on read-write
820 Various code cleanups and minor documentation fixes.
823 LZX and XPRESS decompression have received some additional optimizations
824 and should now be even faster. (Although, they were already pretty
825 fast--- much faster than typical I/O speeds.)
827 Fixed a bug introduced in v1.2.1 that would cause a directory tree
828 containing hard links to be captured incorrectly in some cases.
831 By default, unmounting a read-write mounted WIM with 'imagex unmount
832 --commit' will now change the WIM in-place without needing to write the
833 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
836 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
837 for a response from the daemon servicing the mounted WIM. Instead,
838 every second 'imagex unmount' will check if the daemon is still alive,
839 and keep waiting if so, otherwise terminate with an error.
841 'imagex unmount --commit' on a read-write mounted WIM will now print
842 progress information regarding the writing of new or modified streams
843 the WIM, just like when capturing or appending a WIM.
845 A small change has been made to XPRESS compression and it should improve
846 the compression ratio slightly.
848 A change was made that may improve performance slightly when applying a
849 WIM image to a NTFS volume.
851 Microsoft has managed to introduce even more bugs into their software,
852 and now the WIMs for Windows 8 have incorrect (too low) reference counts
853 for some streams. This is unsafe because such streams can be removed
854 when they are in actuality still referenced in the WIM (perhaps by a
855 different image). wimlib will now work around this problem by fixing
856 the stream reference counts. This is only done when wimlib_delete_image() is
857 called ('imagex delete') or when wimlib_mount_image() is called with
858 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
859 requires reading the metadata for all images in the WIM, so this will
860 make these operations noticably slower on WIMs with multiple images.
862 Various other bugfixes.
865 Appending images to a WIM is now be done by default without re-building
866 the whole WIM. Use the --rebuild flag to get the old behavior (which
867 was to re-build the entire WIM when a new image is appended).
869 A new command `imagex optimize' is now available to manually re-build a
870 WIM that has wasted space due to repeated appends.
872 Progress information has been improved, and now arbitrary callback
873 functions can be used to show the progress of a WIM operation.
875 A possible bug with changing the bootable image of a WIM was fixed.
877 Some advisory locking is now done to prevent two processes from
878 modifying a WIM at the same time (but only in some cases). For example,
879 you cannot mount two images from a WIM read-write at the same time.
881 Some functions have been reorganized:
882 * wimlib_mount() renamed to wimlib_mount_image().
883 * wimlib_unmount() renamed to wimlib_unmount_image().
884 * wimlib_overwrite_xml_and_header() removed as
885 wimlib_overwrite() suffices now.
886 * wimlib_apply_image_to_ntfs_volume() removed as
887 wimlib_extract_image() suffices now.
888 * wimlib_add_image_from_ntfs_volume() removed as
889 * wimlib_add_image() suffices now.
891 Previously, the soname of libwim.so has been 0.0.0, despite many
892 interface changes. The soname is now updated to 1.0.0 and will now be
893 updated each release.
896 Resources will now be compressed using multiple threads by default.
897 (This applies to `imagex capture', `imagex append', and `imagex
900 Some performance improvements in mounted WIMs.
902 More progress information is shown when capturing a WIM.
905 Lots of minor fixes, code cleanups, and some documentation updates.
906 Nothing in particular is really noteworthy.
909 LZX and XPRESS compression improvements.
911 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
912 Link Bytes of the WIM.
915 Fixed bug when capturing NTFS file with multiple named data streams.
917 Internally, we are now using inode structures, even though these don't
918 appear literally in the WIM file. This simplifies some of the code
919 (mainly for WIM mounting) and likely fixed a few problems, although it
923 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
927 Enough changes to call it version 1.0.0!
929 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
930 to a NTFS volume, is now supported.
932 Hard links and symbolic links have much improved support. They are
933 supported for WIM capture, WIM application, and mounted WIMs (you can
934 even make them on read-write mounted WIMs).
936 Alternate data streams are now supported on mounted WIMs through an
937 xattr or a Windows-style stream interface. Also they are supported when
938 capturing a WIM from NTFS or applying a WIM to NTFS.
940 Split WIMs are better supported. You may now apply an image directly
941 from a split WIM, mount an image from a split WIM read-only, or export
942 an image from a split WIM.
944 Using a capture configuration file is now supported (but not fully yet).
946 SHA1 message digests are checked in more places, so we can make sure
947 applied and captured data is correct.
949 Man pages have been updated and consolidated.
952 Fixed segfault when unmounting read-only WIM.
955 Support for joining and splitting WIMs.
956 Also, security data is now preserved by default.
959 Can now build with older gcc and system headers, like on CentOS 5.
962 Fixed bug that made it impossible to overwrite files in read-write
966 Write byte-order mark before WIM XML data. (imagex.exe requires this to
