2 Reduced memory usage when exporting large numbers of WIM images.
4 VSS support is no longer marked "experimental".
6 Made some minor build-related updates. Notably, enabled "silent" make
7 rules; this makes the output cleaner when building from source.
10 Added experimental support for Windows VSS (Volume Shadow Copy Service).
11 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
12 create and use a temporary VSS snapshot when capturing a WIM image.
14 Implemented setting of Windows-specific XML information, such as
15 architecture, system root, and version details. This information is now
16 automatically set in newly captured WIM images, when appropriate.
18 Improved performance of directory tree scans on Windows.
20 On Windows, to improve capture performance, wimlib now sometimes opens
21 files by inode number rather than by path. This is enabled for
22 wimcapture and wimappend, but for now other applications have to opt-in.
24 The progress messages printed by wimlib-imagex while writing WIM files
25 have been slightly tweaked.
27 Progress information for directory tree scans now counts all hard links.
28 Also, on Windows "\\?\" is no longer stripped from the current path.
30 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
31 'wiminfo'. This option lets you assign values to elements in a WIM
32 file's XML document by name.
34 The wimlib_get_image_property() and wimlib_set_image_property() API
35 functions now support numerically indexed elements.
37 Fixed a bug where, on Windows, wimlib would change the security
38 descriptor of the target directory of an extraction even when the
39 '--no-acls' option was specified.
42 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
43 some Microsoft software would not correctly recognize data in the
46 Made some small improvements to the compression algorithms:
47 LZX compression ratio was slightly improved.
48 XPRESS compression ratio and speed was slightly improved.
49 LZMS compression speed was slightly improved.
51 Improved handling of WIM XML data. wimlib no longer drops unrecognized
52 elements when exporting images. In addition, two API functions were
53 added for better access to elements in the XML document:
54 wimlib_get_image_property() and wimlib_set_image_property().
56 Added support for (unsafe) in-place compaction of WIM files.
58 Improved performance of image export by reusing metadata resources
59 instead of always rebuilding and recompressing them.
61 Improved performance of wimlib_update_image() by delaying the update to
62 the WIM's XML document until a write is requested.
64 On Windows, the target of an extraction may now be a reparse point
65 (which will be dereferenced).
67 On Windows, wimlib now correctly restores non-Microsoft reparse points.
68 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
70 On Windows, wimlib now has improved performance when archiving files
71 from a filesystem backed by a WIM (a "WIMBoot" setup).
73 Several improvements to System Compression (compact mode) support:
75 wof.sys (or wofadk.sys) is now automatically attached to the
76 target volume if needed.
78 Compact-mode extractions now work correctly with wofadk.sys on
79 older versions of Windows.
81 For compatibility with the Windows bootloader, the requested
82 compression format now is overridden on certain files.
87 This release primarily contains various minor bug fixes and
88 improvements, including:
90 Improved handling of deep directory structures.
92 Fixed a bug where on 32-bit systems, the library could enter an
93 infinite loop if a WIM file was malformed in a specific way.
95 Added a workaround for a case where libntfs-3g may report
96 duplicate streams in an NTFS file.
98 Windows symbolic links and junctions in mounted WIM images are
99 now automatically rewritten to be valid in the mounted location.
101 Reparse point fixes: correctly handle the "ReparseReserved"
102 field, and correctly handle "empty" (data-less) reparse points.
104 On Windows, wimlib now acquires SeManageVolumePrivilege, which
105 is needed to create externally backed files using the
108 Improved validation of filenames.
110 Improved LZMS decompression speed.
112 The configure script now honors alternate pkg-config settings.
114 Links have been updated to point to the new website.
116 In addition, experimental support has been added for compressing
117 extracted files using System Compression on Windows 10. This
118 functionality is available through the new '--compact' option to
119 'wimapply' and 'wimextract' as well as new library flags.
122 Fixed a bug in the LZX decompressor: malicious input data could cause
123 out of bounds writes to memory (since wimlib v1.2.2).
125 The output of the 'wiminfo' command now consolidates various boolean
126 flags (such as "Relative path junction") into a single line.
128 A file can now have both an unnamed data stream ("file contents") and a
129 reparse point stream. Such files can exist as a result of the use of
130 certain Windows features, such as offline storage, including "OneDrive".
131 wimlib will now store and restore both streams on Windows as well as in
132 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
134 On Windows, named data streams of encrypted files are no longer stored
135 twice in WIM archives.
137 On Windows, named data streams are now correctly extracted to existing
138 "readonly" directories. Before, an error would be reported.
140 On Windows, it is now possible to do a "WIMBoot mode" extraction with
141 non-standalone WIMs such as delta WIMs.
143 On Windows, when doing an extraction in "WIMBoot mode", files larger
144 than 4 gigabytes are now never extracted as externally backed. This
145 works around a bug in Microsoft's "WOF" driver.
147 The '--enable-verify-compression' configure option has been removed. If
148 you want to verify a WIM file, use the 'wimverify' program.
150 The way the "file count", "directory count", "total bytes", and "hard
151 link bytes" image statistics (stored in the WIM XML data) is calculated
152 has been slightly changed.
154 In mounted WIM images, the disk usage provided for each file (st_blocks)
155 is now the compressed size rather than the uncompressed size.
157 The performance of the NTFS-3g and Windows capture modes has been
160 On UNIX-like systems, symbolic links whose targets contain the backslash
161 character are now handled correctly (losslessly).
164 Improved the LZX compressor. It is now 15-20% faster than before and
165 provides a slightly better compression ratio.
167 Improved the LZMS compressor. It now provides a compression ratio
168 slightly better than WIMGAPI while still being faster and using slightly
171 The compression chunk size in solid resources, e.g. when capturing or
172 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
173 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
174 better compression ratio and is the same value that WIMGAPI uses. The
175 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
176 lower than WIMGAPI's memory usage, but if it is too much, it is still
177 possible to choose a lower value, e.g. with the '--solid-chunk-size'
178 option to wimlib-imagex.
180 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
181 accept the 'K', 'M', and 'G' suffixes.
183 Files are now sorted by name extension when creating a solid WIM file.
185 Fixed various issues related to capture/apply of EFS-encrypted files on
188 The file list printed by 'wimdir' is now sorted by the platform-specific
189 case sensitivity setting, rather than always case sensitively. This
190 also affects the library function wimlib_iterate_dir_tree().
192 On Windows, some error and warning messages have been improved.
195 The Windows binary distribution no longer contains third party DLLs.
196 These dependencies are instead compiled directly into the libwim DLL.
198 Added more fixes for wimlib on non-x86 architectures such as ARM.
200 Extracting files to a Windows PE in-memory filesystem no longer fails if
201 the target files do not yet exist.
203 Improved the performance of XPRESS compression and LZMS decompression.
205 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
206 It will automatically be faster on newer Intel and AMD processors.
208 Removed the --with-imagex-progname and --enable-more-assertions
212 Fix for very slow export from solid WIM / ESD files.
214 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
216 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
217 may use this to treat some types of errors as non-fatal.
219 The library now permits making in-memory changes to a WIMStruct backed
220 by a read-only WIM file.
222 Fixes for "WIMBoot" extraction mode (Windows only):
224 When not using the WOF driver, extraction no longer fails if the
225 disk containing the WIM file has too many partitions.
227 When matching patterns in [PrepopulateList], all hard links of
228 each file are now considered.
230 The system registry files are now automatically treated as being
231 in [PrepopulateList].
233 Added a hack to try to work around an intermittent bug in
234 Microsoft's WOF (Windows Overlay Filesystem) driver.
237 Made more improvements to the XPRESS, LZX, and LZMS compressors.
239 A number of improvements to the Windows port:
241 Fixes for setting short filenames.
243 Faster "WIMBoot" extraction.
245 Updated and slimmed down the dependent DLLs.
247 ACL inheritence bits are now restored.
249 Mandatory integrity labels are now backed up and restored.
251 Added a workaround for an issue where in rare cases, wimlib could create
252 a compressed data stream that could not be read correctly by Windows
253 after an extraction in "WIMBoot" mode.
256 Added file count progress data for
257 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
258 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
260 Added support for testing file exclusions via the user-provided
263 Some documentation improvements.
265 Made some clarifications to the license text in the COPYING file.
268 Made more improvements to the XPRESS, LZX, and LZMS compressors.
270 The default compression mode for wimcapture is now LZX compression in
271 its default mode, which is the same as '--compress=maximum'.
273 You can now specify an optional integer compression level to the
274 '--compress' option; e.g. '--compress=lzx:75'.
276 Made a minor change to the LZMS compressor and decompressor to fix an
277 incompatibility with the Microsoft implementation. In the unlikely
278 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
279 earlier and a checksum error is reported when extracting files from it
280 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
283 Added 'verify' subcommand to wimlib-imagex.
285 Notable library changes:
287 Custom compressor parameters have been removed from the library
288 in favor of the simpler level-based API.
290 Decompressor parameters have been removed entirely.
292 Library users can now specify a custom file for warning and
293 error messages to be sent to, rather than the default of
296 New progress messages:
297 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
298 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
300 New function: wimlib_verify_wim().
303 Improved compression, decompression, and extraction performance.
305 Improved compatibility with version 3584 WIM / ESD files:
306 - Add support for reading and writing multiple solid blocks per
307 archive, which WIMGAPI/DISM can create when appending an image.
308 - Correctly create solid blocks larger than 4 GiB.
310 'add' commands passed to wimupdate will now replace existing
311 nondirectory files by default. Use the --no-replace option to get the
314 The license for the library now contains an exception that allows using
315 it under the LGPL. See the COPYING file for details.
317 In reparse-point fixup mode (the default for capture), symbolic links
318 and junctions that point outside the tree being captured are no longer
319 excluded from capture.
321 Added support for "WIMBoot" capture and extraction. See the
322 documentation for the new '--wimboot' option to wimcapture and wimapply
323 for more information.
325 On UNIX-like systems, you can now backup and restore device nodes, named
326 pipes, and sockets. In addition, 32-bit user and group IDs are now
329 The way that UNIX data is stored in WIM files has been changed. If you
330 captured any WIMs with the --unix-data option, to upgrade them you'll
331 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
332 re-capture them with --unix-data using this version.
334 wimlib now understands tagged metadata items, such as object IDs, that
335 can be stored in WIM directory entries.
337 Removed the --hardlink and --symlink options to wimapply, since I don't
338 think they are too useful and they got in the way of improving the code.
340 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
342 The 'mkwinpeimg' script now supports writing the ISO image to standard
345 The <ARCH> element in WIM XML data is now exported correctly.
347 On Windows, sparse file attributes are no longer set on extracted files.
348 Oddly enough, this actually saves disk space in some cases.
350 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
351 supported. Mounting WIM images now always requires extended attribute
352 support. Use --without-fuse to disable support for mounting WIM images;
353 this will also disable the need for extended attribute support.
355 Configuring with --enable-ssse3-sha1 now works correctly.
357 The shared library version has been bumped up. The main
358 incompatibilities are:
360 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
361 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
364 - User-provided progress functions are now registered using a
365 separate function, wimlib_register_progress_function(). The
366 'progress_func' argument to many functions no longer exists.
368 - The return value from user-provided progress functions is now
371 - A context argument has been added to the prototype of
372 user-provided progress functions.
374 - 'struct wimlib_capture_config' has been removed. The library
375 now takes the path to the configuration file directly. This
376 affects wimlib_add_image(), wimlib_add_image_multisource(),
377 and wimlib_update_image(). However, a NULL value passed in
378 the argument retains the same meaning.
380 - Removed deprecated functions: some (de)compression functions,
381 wimlib_extract_files(), and wimlib_print_metadata().
383 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
384 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
385 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
387 - Removed some progress messages:
388 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
389 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
390 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
393 - Removed some error codes. Numbering stays the same.
395 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
396 WIMLIB_UNMOUNT_FLAG_FORCE.
398 - WIM paths passed to progress functions now have a leading
402 Case-insensitive comparisons of strings (e.g. filenames) containing
403 UTF-16 codepoints above 32767 are now done correctly.
405 Fixed build failure on Mac OS X.
407 wimunmount now provides the '--new-image' option to cause changes to a
408 read-write mounted image to be committed as a new image rather than as
409 an update of the mounted image. (The corresponding new library flag is
410 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
412 The LZMS ("recovery") compression chunk size, or "dictionary size", may
413 now be up to 1 GiB (1,073,741,824 bytes).
415 The performance of LZX ("maximum") and LZMS ("recovery") compression
416 with large chunk sizes has been slightly improved.
419 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
420 decompressed correctly.
422 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
423 occurred in an unlikely case, and due to validity checks it did not
424 affect successfully created archives.
426 Fixed a minor compatibility issue with the LZMS compressor and
427 decompressor. This is *not* the default compression type and was only
428 introduced in v1.6.0. In the unlikely event that you created an
429 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
430 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
433 Memory usage for LZMS and LZX compression has been decreased.
435 wimextract now allows wildcard characters in paths specified on the
436 command line. Also, the '--strict-wildcards' option has been removed
437 and replaced with the inverse option '--nullglob'. See the
438 documentation for wimextract for more details and changes.
440 The wimlib_extract_files() function is now considered deprecated in
441 favor of wimlib_extract_paths().
443 Fixed more permissions problems when extracting files on Windows.
445 A new '--no-attributes' option has been added to wimapply and
446 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
448 The default chunk size is now set correctly when changing the
449 compression type of a WIM, for example with 'wimoptimize'.
451 The '--metadata' option to wiminfo has been replaced with the
452 '--detailed' option to wimdir.
454 In relevant wimlib-imagex commands, '--solid' may now be used as an
455 alias for '--pack-streams'.
458 Support for extracting and updating the new version 3584 WIMs has been
459 added. These WIMs typically pack many streams ("files") together into a
460 single compressed resource, thereby saving space. This degrades the
461 performance of random access (such as that which occurs on a mounted
462 image), but optimizations have been implemented for extraction. These
463 new WIM files also typically use a new compression format (LZMS), which
464 is similar to LZMA and can offer a better compression ratio than LZX.
465 These new WIM files can be created using `wimcapture' with
466 the '--compress=lzms --pack-streams' options. Note: this new WIM format
467 is used by the Windows 8 web downloader, but important segments of the
468 raw '.esd' files are encrypted, so wimlib will not be able to extract
469 such files until they are first decrypted.
471 wimlib now supports extracting files and directories from a WIM image
472 based on a "listfile" that itself contains the list of paths to extract.
473 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
474 and for the library itself, the new APIs are wimlib_extract_pathlist()
475 and wimlib_extract_paths(). Path globs containing wildcard characters
478 For searching WIM files, wimlib now has configurable case sensitivity.
479 The default on Windows is still case-insensitive and the default on
480 UNIX-like systems is still case-sensitive, but this can be overridden
481 on either platform through flags to wimlib_global_init(). For
482 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
483 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
486 Support for compression chunk sizes greater than the default of 32768
487 bytes has been added. A larger chunk size typically results in a better
488 compression ratio. However, the MS implementation is seemingly not
489 compatible with all chunk sizes, especially for LZX compression, so the
490 defaults remain unchanged, with the exception of the new LZMS-compressed
491 WIMs, which use a larger chunk size by default.
493 The compression/decompression API exported by wimlib has been changed.
494 Now one set of functions handles all supported compression formats.
496 `wimcapture' and `wimappend' will now display the progress of scanning
497 the directory tree to capture, in addition to the progress of writing
498 data to the WIM. The '--verbose' option no longer does anything. The
499 library API change for this is the addition of several members to
500 `struct wimlib_progress_info_scan' available to progress callbacks.
502 `mkwinpeimg' now correctly handles the '--start-script' option when the
503 start script is not in the working directory.
505 Sequential extraction, previously requested by using
506 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
507 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
508 behavior (extract in file order).
511 The new LZX compressor added in v1.5.2 has been improved and is now
512 enabled by default, except when `wimcapture' or `wimappend' is run
513 *without* the '--compress' option, in which case the faster LZX
514 compressor is used (the same as before). This behavior is reasonably
515 consistent with ImageX which actually uses "fast" (XPRESS) compression
516 by default. In those cases, use '--compress=maximum' to explicitly
517 capture a WIM image using the new (slower but better) LZX compressor.
519 The '--compress-slow' option still exists to `wimlib-imagex optimize',
520 but its new behavior is to tweak the new LZX compressor even more to
521 produce an even better compression ratio at the cost of more time spent
524 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
525 which recompresses the WIM file using the specified compression TYPE.
526 The new library API function used for this is
527 wimlib_set_output_compression_type().
529 Added the wimlib_get_xml_data() function to allow library clients to
530 easily retrieve the raw XML data from a WIM file if needed.
532 Fixed a bug that could cause an error code to be incorrectly returned
533 when writing XML data containing a <WINDOWS> element.
535 Mounted WIM images will now correctly show the default file stream even
536 if appears in the alternate data stream entries of the corresponding WIM
540 Added a new experimental LZX compressor which can be enabled by passing
541 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
542 optimize'. (The latter is only applicable if the WIM is already
543 LZX-compressed and the '--recompress' option is also given.) The
544 experimental compressor is much slower but compresses the data slightly
545 more --- currently usually to within a fraction of a percent of the
546 results from WIMGAPI/ImageX.
548 A workaround has been added for compatibility with versions of WinPE
549 that interpret alternate data stream entries in the boot WIM
552 An alignment bug that caused a crash in the LZX decompressor on some
555 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
556 the WIM header when restoring the previous state of a WIM it failed to
559 Added a workaround to avoid an access denied error on Windows when
560 replacing a WIM file that another process has opened.
563 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
564 needed to be handled.
566 A bug in the interpretation of negative IMAGE indices in the
567 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
568 `wimlib-imagex append' has been fixed.
570 A workaround has been added to successfully apply security descriptors
571 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
572 2013.1.13 or earlier.
574 `wimlib-imagex capture' can now accept the '--delta-from' option
578 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
579 to standard output and applying images from standard input, but they are
580 not compatible with Microsoft's software and are not created by default.
581 See the documentation for --pipable flag of `wimlib-imagex capture' for
584 To better support incremental backups, added support for declaring an
585 image as a modified form of another image. See the documentation for
586 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
589 Added supported for "delta" WIMs. See the documentation for the
590 '--delta-from' option of `wimlib-imagex capture'.
592 The library support for managing split WIMs has been changed to support
593 other arrangements, such as delta WIMs, and be easier to use. This
594 change is visible in `wimlib-imagex', which also can now accept the
595 '--ref' option multiple times, and also now supports "delta" WIMs as
598 wimlib now preserves WIM integrity tables by default, even if
599 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
600 behavior of `wimlib-imagex' whenever the WIM being operated on contains
601 an integrity table and the '--check' option is not specified.
603 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
604 (when --compress is not specified). This provides the best compression
605 ratio by default, which is usually what is desired, at a cost of some
608 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
609 is the command as in `wimlib-imagex COMMAND'; for example, it can be
610 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
611 appropriate hard links are created in UNIX installations of
612 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
613 batch files that emulate this behavior are generated.
615 Security descriptors are now extracted correctly on Windows.
617 Fixed archiving DOS names in NTFS-3g capture mode.
619 The extraction code has been rewritten and it will now be easier to
620 support new features on all supported backends (currently Win32, UNIX,
621 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
622 now supported on all backends, not just UNIX.
624 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
625 than the WAIK itself.
627 wimlib_global_init() now, by default, attempts to acquire additional
628 privileges on Windows, so library clients need not do this.
630 This update bumps the shared library version number up to 9, since it is
631 not binary compatibible with previous releases.
634 Fixed bug in `wimlib-imagex export' that made it impossible to export an
635 image from a WIM that is readonly at the filesystem level.
637 Return error code rather than segfaulting when trying to list files from
638 a non-first part of a split WIM.
640 Joining a WIM will now preserve the RP_FIX and READONLY flags.
643 On Windows, paths given to wimlib-imagex are now treated case
646 Improved behavior regarding invalid filenames; in particular, on
647 Windows, wimlib-imagex will, when extracting, now omit (with an option
648 to override this default) filenames differing only in case, or filenames
649 containing characters not valid on Windows.
651 On Windows, wimlib now supports capturing and extracting long paths
652 (longer than the so-called MAX_PATH).
654 On Windows, `wimlib-imagex update' now acquires proper privileges when
655 running as an Administrator.
657 `wimlib-imagex update' will now complain if no image is specified when
658 trying to update a multi-image WIM.
660 `wimlib-imagex update' now supports specifying a single update command
661 directly on the command line using the --command option.
663 wimlib-imagex will now choose different units for progress messages,
664 depending on the amount of data that needs to be processed.
666 `wimlib-imagex append' will now generate a unique WIM image name if no
667 name is specified and the defaulted name already exists in the WIM.
669 wimlib now allows you to create unnamed WIM images, which can then only
670 be referred to by index.
672 wimlib now allows you to explicitly declare you want write access to a
673 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
676 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
679 Progress callbacks have been added to wimlib's wimlib_update_image()
682 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
683 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
686 NTFS-3g capture now only warns about two conditions previously treated
689 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
692 wimlib now correctly detects and returns an error when reading a WIM
693 image with a cyclic directory structure. (Fun fact: such a WIM will
694 crash Microsoft's software.)
697 Added new "extract" and "update" subcommands to wimlib-imagex, along
698 with associated APIs in the library. These commands are intended mainly
699 for Windows use but can be used on UNIX as well.
701 Many documentation improvements.
703 Fixed a bug in the Windows build where relative symbolic links were not
704 captured in reparse-point fixup mode.
706 Fixed a bug in the Windows build where file handles were left open to
707 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
709 Fixed a bug in the Windows build of wimlib-imagex where globbing
710 split-WIM parts could cause the program to crash.
712 Fixed a bug where the creation time of WIM images would be shown instead
713 of the last modification time.
715 With the Windows build it is now possible to restore a WIM containing
716 symbolic links as a non-Administrator; however you will receive warnings
717 about not being able to extract the symbolic links.
720 Capturing a WIM image should now be significantly faster in most cases
721 due to improved use of the operating system's cache and avoiding reading
722 files twice whenever possible.
724 The Windows build should now work on Windows XP.
726 The Windows build now supports capturing and restoring hidden,
727 compressed, sparse, and encrypted files.
729 The Windows build now supports capturing and applying WIM images from
730 filesystems other than NTFS (with some reduced functionality).
732 The Windows build now extracts short names correctly.
734 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
735 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
736 capture' and `wimlib-imagex apply'.
738 The performance of splitting and joining WIMs should be slightly
741 The LZX and XPRESS compression and decompression functions are now
742 exported from the library.
745 Improvements and bugfixes for the Windows build.
747 Added --strict-acls options.
749 Fixed the way that wimlib determines the order of images in the WIM.
752 Since wimlib can now be used on Windows, wimlib's implementation of
753 ImageX has been renamed to wimlib-imagex to avoid confusion with
754 Microsoft's implementation of ImageX, which would have the same file
755 name ("imagex.exe"). If you really don't like this you can pass the
756 --with-imagex-progname option to `configure' to choose a different name,
757 or even simply rename the binary yourself (but the former way will
758 configure the man pages to use the chosen name).
760 Various bugs fixed in the Windows build. Mainly to do with capturing
761 and restoring alternate data streams correctly in weird cases, and
762 requesting the correct privileges when opening files. Also added the
763 --noacls options to wimlib-imagex capture, append, and apply.
765 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
766 dynamically loaded, so this may make the library compatible with Windows
767 XP (however, there may still be other problems).
770 Added experimental support for native Windows builds. Binaries can be
771 downloaded from the SourceForge page.
773 --source-list option added to `imagex capture' and `imagex append'.
775 Better support for different character encodings.
778 Storing UNIX file owners, groups, and modes in WIM images is now
779 possible using `imagex capture' with the --unix-data flag.
781 Minor bug fixes and documentation fixes.
784 NTFS capture: Fixed capturing duplicate reparse points.
786 NTFS capture: Capture first unnamed stream if there are more than one
787 (print warning instead of error).
789 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
792 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
795 Update to work with ntfs-3g version 2013.1.13.
798 Fixed truncating file to shorter but non-zero length on read-write
801 Various code cleanups and minor documentation fixes.
804 LZX and XPRESS decompression have received some additional optimizations
805 and should now be even faster. (Although, they were already pretty
806 fast--- much faster than typical I/O speeds.)
808 Fixed a bug introduced in v1.2.1 that would cause a directory tree
809 containing hard links to be captured incorrectly in some cases.
812 By default, unmounting a read-write mounted WIM with 'imagex unmount
813 --commit' will now change the WIM in-place without needing to write the
814 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
817 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
818 for a response from the daemon servicing the mounted WIM. Instead,
819 every second 'imagex unmount' will check if the daemon is still alive,
820 and keep waiting if so, otherwise terminate with an error.
822 'imagex unmount --commit' on a read-write mounted WIM will now print
823 progress information regarding the writing of new or modified streams
824 the WIM, just like when capturing or appending a WIM.
826 A small change has been made to XPRESS compression and it should improve
827 the compression ratio slightly.
829 A change was made that may improve performance slightly when applying a
830 WIM image to a NTFS volume.
832 Microsoft has managed to introduce even more bugs into their software,
833 and now the WIMs for Windows 8 have incorrect (too low) reference counts
834 for some streams. This is unsafe because such streams can be removed
835 when they are in actuality still referenced in the WIM (perhaps by a
836 different image). wimlib will now work around this problem by fixing
837 the stream reference counts. This is only done when wimlib_delete_image() is
838 called ('imagex delete') or when wimlib_mount_image() is called with
839 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
840 requires reading the metadata for all images in the WIM, so this will
841 make these operations noticably slower on WIMs with multiple images.
843 Various other bugfixes.
846 Appending images to a WIM is now be done by default without re-building
847 the whole WIM. Use the --rebuild flag to get the old behavior (which
848 was to re-build the entire WIM when a new image is appended).
850 A new command `imagex optimize' is now available to manually re-build a
851 WIM that has wasted space due to repeated appends.
853 Progress information has been improved, and now arbitrary callback
854 functions can be used to show the progress of a WIM operation.
856 A possible bug with changing the bootable image of a WIM was fixed.
858 Some advisory locking is now done to prevent two processes from
859 modifying a WIM at the same time (but only in some cases). For example,
860 you cannot mount two images from a WIM read-write at the same time.
862 Some functions have been reorganized:
863 * wimlib_mount() renamed to wimlib_mount_image().
864 * wimlib_unmount() renamed to wimlib_unmount_image().
865 * wimlib_overwrite_xml_and_header() removed as
866 wimlib_overwrite() suffices now.
867 * wimlib_apply_image_to_ntfs_volume() removed as
868 wimlib_extract_image() suffices now.
869 * wimlib_add_image_from_ntfs_volume() removed as
870 * wimlib_add_image() suffices now.
872 Previously, the soname of libwim.so has been 0.0.0, despite many
873 interface changes. The soname is now updated to 1.0.0 and will now be
874 updated each release.
877 Resources will now be compressed using multiple threads by default.
878 (This applies to `imagex capture', `imagex append', and `imagex
881 Some performance improvements in mounted WIMs.
883 More progress information is shown when capturing a WIM.
886 Lots of minor fixes, code cleanups, and some documentation updates.
887 Nothing in particular is really noteworthy.
890 LZX and XPRESS compression improvements.
892 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
893 Link Bytes of the WIM.
896 Fixed bug when capturing NTFS file with multiple named data streams.
898 Internally, we are now using inode structures, even though these don't
899 appear literally in the WIM file. This simplifies some of the code
900 (mainly for WIM mounting) and likely fixed a few problems, although it
904 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
908 Enough changes to call it version 1.0.0!
910 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
911 to a NTFS volume, is now supported.
913 Hard links and symbolic links have much improved support. They are
914 supported for WIM capture, WIM application, and mounted WIMs (you can
915 even make them on read-write mounted WIMs).
917 Alternate data streams are now supported on mounted WIMs through an
918 xattr or a Windows-style stream interface. Also they are supported when
919 capturing a WIM from NTFS or applying a WIM to NTFS.
921 Split WIMs are better supported. You may now apply an image directly
922 from a split WIM, mount an image from a split WIM read-only, or export
923 an image from a split WIM.
925 Using a capture configuration file is now supported (but not fully yet).
927 SHA1 message digests are checked in more places, so we can make sure
928 applied and captured data is correct.
930 Man pages have been updated and consolidated.
933 Fixed segfault when unmounting read-only WIM.
936 Support for joining and splitting WIMs.
937 Also, security data is now preserved by default.
940 Can now build with older gcc and system headers, like on CentOS 5.
943 Fixed bug that made it impossible to overwrite files in read-write
947 Write byte-order mark before WIM XML data. (imagex.exe requires this to
