2 Added experimental support for Windows VSS (Volume Shadow Copy Service).
3 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
4 create and use a temporary VSS snapshot when capturing a WIM image.
6 Implemented setting of Windows-specific XML information, such as
7 architecture, system root, and version details. This information is now
8 automatically set in newly captured WIM images, when appropriate.
10 Significantly improved performance of directory scans of full NTFS
11 volumes on Windows 8 and later.
13 The progress messages printed by wimlib-imagex while writing WIM files
14 have been slightly tweaked.
16 Progress information for directory tree scans now counts all hard links.
17 Also, on Windows "\\?\" is no longer stripped from the current path.
19 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
20 'wiminfo'. This option lets you assign values to elements in a WIM
21 file's XML document by name.
23 The wimlib_get_image_property() and wimlib_set_image_property() API
24 functions now support numerically indexed elements.
26 Fixed a bug where, on Windows, wimlib would change the security
27 descriptor of the target directory of an extraction even when the
28 '--no-acls' option was specified.
31 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
32 some Microsoft software would not correctly recognize data in the
35 Made some small improvements to the compression algorithms:
36 LZX compression ratio was slightly improved.
37 XPRESS compression ratio and speed was slightly improved.
38 LZMS compression speed was slightly improved.
40 Improved handling of WIM XML data. wimlib no longer drops unrecognized
41 elements when exporting images. In addition, two API functions were
42 added for better access to elements in the XML document:
43 wimlib_get_image_property() and wimlib_set_image_property().
45 Added support for (unsafe) in-place compaction of WIM files.
47 Improved performance of image export by reusing metadata resources
48 instead of always rebuilding and recompressing them.
50 Improved performance of wimlib_update_image() by delaying the update to
51 the WIM's XML document until a write is requested.
53 On Windows, the target of an extraction may now be a reparse point
54 (which will be dereferenced).
56 On Windows, wimlib now correctly restores non-Microsoft reparse points.
57 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
59 On Windows, wimlib now has improved performance when archiving files
60 from a filesystem backed by a WIM (a "WIMBoot" setup).
62 Several improvements to System Compression (compact mode) support:
64 wof.sys (or wofadk.sys) is now automatically attached to the
65 target volume if needed.
67 Compact-mode extractions now work correctly with wofadk.sys on
68 older versions of Windows.
70 For compatibility with the Windows bootloader, the requested
71 compression format now is overridden on certain files.
76 This release primarily contains various minor bug fixes and
77 improvements, including:
79 Improved handling of deep directory structures.
81 Fixed a bug where on 32-bit systems, the library could enter an
82 infinite loop if a WIM file was malformed in a specific way.
84 Added a workaround for a case where libntfs-3g may report
85 duplicate streams in an NTFS file.
87 Windows symbolic links and junctions in mounted WIM images are
88 now automatically rewritten to be valid in the mounted location.
90 Reparse point fixes: correctly handle the "ReparseReserved"
91 field, and correctly handle "empty" (data-less) reparse points.
93 On Windows, wimlib now acquires SeManageVolumePrivilege, which
94 is needed to create externally backed files using the
97 Improved validation of filenames.
99 Improved LZMS decompression speed.
101 The configure script now honors alternate pkg-config settings.
103 Links have been updated to point to the new website.
105 In addition, experimental support has been added for compressing
106 extracted files using System Compression on Windows 10. This
107 functionality is available through the new '--compact' option to
108 'wimapply' and 'wimextract' as well as new library flags.
111 Fixed a bug in the LZX decompressor: malicious input data could cause
112 out of bounds writes to memory (since wimlib v1.2.2).
114 The output of the 'wiminfo' command now consolidates various boolean
115 flags (such as "Relative path junction") into a single line.
117 A file can now have both an unnamed data stream ("file contents") and a
118 reparse point stream. Such files can exist as a result of the use of
119 certain Windows features, such as offline storage, including "OneDrive".
120 wimlib will now store and restore both streams on Windows as well as in
121 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
123 On Windows, named data streams of encrypted files are no longer stored
124 twice in WIM archives.
126 On Windows, named data streams are now correctly extracted to existing
127 "readonly" directories. Before, an error would be reported.
129 On Windows, it is now possible to do a "WIMBoot mode" extraction with
130 non-standalone WIMs such as delta WIMs.
132 On Windows, when doing an extraction in "WIMBoot mode", files larger
133 than 4 gigabytes are now never extracted as externally backed. This
134 works around a bug in Microsoft's "WOF" driver.
136 The '--enable-verify-compression' configure option has been removed. If
137 you want to verify a WIM file, use the 'wimverify' program.
139 The way the "file count", "directory count", "total bytes", and "hard
140 link bytes" image statistics (stored in the WIM XML data) is calculated
141 has been slightly changed.
143 In mounted WIM images, the disk usage provided for each file (st_blocks)
144 is now the compressed size rather than the uncompressed size.
146 The performance of the NTFS-3g and Windows capture modes has been
149 On UNIX-like systems, symbolic links whose targets contain the backslash
150 character are now handled correctly (losslessly).
153 Improved the LZX compressor. It is now 15-20% faster than before and
154 provides a slightly better compression ratio.
156 Improved the LZMS compressor. It now provides a compression ratio
157 slightly better than WIMGAPI while still being faster and using slightly
160 The compression chunk size in solid resources, e.g. when capturing or
161 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
162 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
163 better compression ratio and is the same value that WIMGAPI uses. The
164 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
165 lower than WIMGAPI's memory usage, but if it is too much, it is still
166 possible to choose a lower value, e.g. with the '--solid-chunk-size'
167 option to wimlib-imagex.
169 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
170 accept the 'K', 'M', and 'G' suffixes.
172 Files are now sorted by name extension when creating a solid WIM file.
174 Fixed various issues related to capture/apply of EFS-encrypted files on
177 The file list printed by 'wimdir' is now sorted by the platform-specific
178 case sensitivity setting, rather than always case sensitively. This
179 also affects the library function wimlib_iterate_dir_tree().
181 On Windows, some error and warning messages have been improved.
184 The Windows binary distribution no longer contains third party DLLs.
185 These dependencies are instead compiled directly into the libwim DLL.
187 Added more fixes for wimlib on non-x86 architectures such as ARM.
189 Extracting files to a Windows PE in-memory filesystem no longer fails if
190 the target files do not yet exist.
192 Improved the performance of XPRESS compression and LZMS decompression.
194 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
195 It will automatically be faster on newer Intel and AMD processors.
197 Removed the --with-imagex-progname and --enable-more-assertions
201 Fix for very slow export from solid WIM / ESD files.
203 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
205 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
206 may use this to treat some types of errors as non-fatal.
208 The library now permits making in-memory changes to a WIMStruct backed
209 by a read-only WIM file.
211 Fixes for "WIMBoot" extraction mode (Windows only):
213 When not using the WOF driver, extraction no longer fails if the
214 disk containing the WIM file has too many partitions.
216 When matching patterns in [PrepopulateList], all hard links of
217 each file are now considered.
219 The system registry files are now automatically treated as being
220 in [PrepopulateList].
222 Added a hack to try to work around an intermittent bug in
223 Microsoft's WOF (Windows Overlay Filesystem) driver.
226 Made more improvements to the XPRESS, LZX, and LZMS compressors.
228 A number of improvements to the Windows port:
230 Fixes for setting short filenames.
232 Faster "WIMBoot" extraction.
234 Updated and slimmed down the dependent DLLs.
236 ACL inheritence bits are now restored.
238 Mandatory integrity labels are now backed up and restored.
240 Added a workaround for an issue where in rare cases, wimlib could create
241 a compressed data stream that could not be read correctly by Windows
242 after an extraction in "WIMBoot" mode.
245 Added file count progress data for
246 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
247 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
249 Added support for testing file exclusions via the user-provided
252 Some documentation improvements.
254 Made some clarifications to the license text in the COPYING file.
257 Made more improvements to the XPRESS, LZX, and LZMS compressors.
259 The default compression mode for wimcapture is now LZX compression in
260 its default mode, which is the same as '--compress=maximum'.
262 You can now specify an optional integer compression level to the
263 '--compress' option; e.g. '--compress=lzx:75'.
265 Made a minor change to the LZMS compressor and decompressor to fix an
266 incompatibility with the Microsoft implementation. In the unlikely
267 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
268 earlier and a checksum error is reported when extracting files from it
269 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
272 Added 'verify' subcommand to wimlib-imagex.
274 Notable library changes:
276 Custom compressor parameters have been removed from the library
277 in favor of the simpler level-based API.
279 Decompressor parameters have been removed entirely.
281 Library users can now specify a custom file for warning and
282 error messages to be sent to, rather than the default of
285 New progress messages:
286 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
287 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
289 New function: wimlib_verify_wim().
292 Improved compression, decompression, and extraction performance.
294 Improved compatibility with version 3584 WIM / ESD files:
295 - Add support for reading and writing multiple solid blocks per
296 archive, which WIMGAPI/DISM can create when appending an image.
297 - Correctly create solid blocks larger than 4 GiB.
299 'add' commands passed to wimupdate will now replace existing
300 nondirectory files by default. Use the --no-replace option to get the
303 The license for the library now contains an exception that allows using
304 it under the LGPL. See the COPYING file for details.
306 In reparse-point fixup mode (the default for capture), symbolic links
307 and junctions that point outside the tree being captured are no longer
308 excluded from capture.
310 Added support for "WIMBoot" capture and extraction. See the
311 documentation for the new '--wimboot' option to wimcapture and wimapply
312 for more information.
314 On UNIX-like systems, you can now backup and restore device nodes, named
315 pipes, and sockets. In addition, 32-bit user and group IDs are now
318 The way that UNIX data is stored in WIM files has been changed. If you
319 captured any WIMs with the --unix-data option, to upgrade them you'll
320 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
321 re-capture them with --unix-data using this version.
323 wimlib now understands tagged metadata items, such as object IDs, that
324 can be stored in WIM directory entries.
326 Removed the --hardlink and --symlink options to wimapply, since I don't
327 think they are too useful and they got in the way of improving the code.
329 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
331 The 'mkwinpeimg' script now supports writing the ISO image to standard
334 The <ARCH> element in WIM XML data is now exported correctly.
336 On Windows, sparse file attributes are no longer set on extracted files.
337 Oddly enough, this actually saves disk space in some cases.
339 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
340 supported. Mounting WIM images now always requires extended attribute
341 support. Use --without-fuse to disable support for mounting WIM images;
342 this will also disable the need for extended attribute support.
344 Configuring with --enable-ssse3-sha1 now works correctly.
346 The shared library version has been bumped up. The main
347 incompatibilities are:
349 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
350 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
353 - User-provided progress functions are now registered using a
354 separate function, wimlib_register_progress_function(). The
355 'progress_func' argument to many functions no longer exists.
357 - The return value from user-provided progress functions is now
360 - A context argument has been added to the prototype of
361 user-provided progress functions.
363 - 'struct wimlib_capture_config' has been removed. The library
364 now takes the path to the configuration file directly. This
365 affects wimlib_add_image(), wimlib_add_image_multisource(),
366 and wimlib_update_image(). However, a NULL value passed in
367 the argument retains the same meaning.
369 - Removed deprecated functions: some (de)compression functions,
370 wimlib_extract_files(), and wimlib_print_metadata().
372 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
373 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
374 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
376 - Removed some progress messages:
377 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
378 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
379 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
382 - Removed some error codes. Numbering stays the same.
384 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
385 WIMLIB_UNMOUNT_FLAG_FORCE.
387 - WIM paths passed to progress functions now have a leading
391 Case-insensitive comparisons of strings (e.g. filenames) containing
392 UTF-16 codepoints above 32767 are now done correctly.
394 Fixed build failure on Mac OS X.
396 wimunmount now provides the '--new-image' option to cause changes to a
397 read-write mounted image to be committed as a new image rather than as
398 an update of the mounted image. (The corresponding new library flag is
399 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
401 The LZMS ("recovery") compression chunk size, or "dictionary size", may
402 now be up to 1 GiB (1,073,741,824 bytes).
404 The performance of LZX ("maximum") and LZMS ("recovery") compression
405 with large chunk sizes has been slightly improved.
408 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
409 decompressed correctly.
411 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
412 occurred in an unlikely case, and due to validity checks it did not
413 affect successfully created archives.
415 Fixed a minor compatibility issue with the LZMS compressor and
416 decompressor. This is *not* the default compression type and was only
417 introduced in v1.6.0. In the unlikely event that you created an
418 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
419 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
422 Memory usage for LZMS and LZX compression has been decreased.
424 wimextract now allows wildcard characters in paths specified on the
425 command line. Also, the '--strict-wildcards' option has been removed
426 and replaced with the inverse option '--nullglob'. See the
427 documentation for wimextract for more details and changes.
429 The wimlib_extract_files() function is now considered deprecated in
430 favor of wimlib_extract_paths().
432 Fixed more permissions problems when extracting files on Windows.
434 A new '--no-attributes' option has been added to wimapply and
435 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
437 The default chunk size is now set correctly when changing the
438 compression type of a WIM, for example with 'wimoptimize'.
440 The '--metadata' option to wiminfo has been replaced with the
441 '--detailed' option to wimdir.
443 In relevant wimlib-imagex commands, '--solid' may now be used as an
444 alias for '--pack-streams'.
447 Support for extracting and updating the new version 3584 WIMs has been
448 added. These WIMs typically pack many streams ("files") together into a
449 single compressed resource, thereby saving space. This degrades the
450 performance of random access (such as that which occurs on a mounted
451 image), but optimizations have been implemented for extraction. These
452 new WIM files also typically use a new compression format (LZMS), which
453 is similar to LZMA and can offer a better compression ratio than LZX.
454 These new WIM files can be created using `wimcapture' with
455 the '--compress=lzms --pack-streams' options. Note: this new WIM format
456 is used by the Windows 8 web downloader, but important segments of the
457 raw '.esd' files are encrypted, so wimlib will not be able to extract
458 such files until they are first decrypted.
460 wimlib now supports extracting files and directories from a WIM image
461 based on a "listfile" that itself contains the list of paths to extract.
462 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
463 and for the library itself, the new APIs are wimlib_extract_pathlist()
464 and wimlib_extract_paths(). Path globs containing wildcard characters
467 For searching WIM files, wimlib now has configurable case sensitivity.
468 The default on Windows is still case-insensitive and the default on
469 UNIX-like systems is still case-sensitive, but this can be overridden
470 on either platform through flags to wimlib_global_init(). For
471 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
472 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
475 Support for compression chunk sizes greater than the default of 32768
476 bytes has been added. A larger chunk size typically results in a better
477 compression ratio. However, the MS implementation is seemingly not
478 compatible with all chunk sizes, especially for LZX compression, so the
479 defaults remain unchanged, with the exception of the new LZMS-compressed
480 WIMs, which use a larger chunk size by default.
482 The compression/decompression API exported by wimlib has been changed.
483 Now one set of functions handles all supported compression formats.
485 `wimcapture' and `wimappend' will now display the progress of scanning
486 the directory tree to capture, in addition to the progress of writing
487 data to the WIM. The '--verbose' option no longer does anything. The
488 library API change for this is the addition of several members to
489 `struct wimlib_progress_info_scan' available to progress callbacks.
491 `mkwinpeimg' now correctly handles the '--start-script' option when the
492 start script is not in the working directory.
494 Sequential extraction, previously requested by using
495 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
496 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
497 behavior (extract in file order).
500 The new LZX compressor added in v1.5.2 has been improved and is now
501 enabled by default, except when `wimcapture' or `wimappend' is run
502 *without* the '--compress' option, in which case the faster LZX
503 compressor is used (the same as before). This behavior is reasonably
504 consistent with ImageX which actually uses "fast" (XPRESS) compression
505 by default. In those cases, use '--compress=maximum' to explicitly
506 capture a WIM image using the new (slower but better) LZX compressor.
508 The '--compress-slow' option still exists to `wimlib-imagex optimize',
509 but its new behavior is to tweak the new LZX compressor even more to
510 produce an even better compression ratio at the cost of more time spent
513 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
514 which recompresses the WIM file using the specified compression TYPE.
515 The new library API function used for this is
516 wimlib_set_output_compression_type().
518 Added the wimlib_get_xml_data() function to allow library clients to
519 easily retrieve the raw XML data from a WIM file if needed.
521 Fixed a bug that could cause an error code to be incorrectly returned
522 when writing XML data containing a <WINDOWS> element.
524 Mounted WIM images will now correctly show the default file stream even
525 if appears in the alternate data stream entries of the corresponding WIM
529 Added a new experimental LZX compressor which can be enabled by passing
530 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
531 optimize'. (The latter is only applicable if the WIM is already
532 LZX-compressed and the '--recompress' option is also given.) The
533 experimental compressor is much slower but compresses the data slightly
534 more --- currently usually to within a fraction of a percent of the
535 results from WIMGAPI/ImageX.
537 A workaround has been added for compatibility with versions of WinPE
538 that interpret alternate data stream entries in the boot WIM
541 An alignment bug that caused a crash in the LZX decompressor on some
544 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
545 the WIM header when restoring the previous state of a WIM it failed to
548 Added a workaround to avoid an access denied error on Windows when
549 replacing a WIM file that another process has opened.
552 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
553 needed to be handled.
555 A bug in the interpretation of negative IMAGE indices in the
556 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
557 `wimlib-imagex append' has been fixed.
559 A workaround has been added to successfully apply security descriptors
560 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
561 2013.1.13 or earlier.
563 `wimlib-imagex capture' can now accept the '--delta-from' option
567 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
568 to standard output and applying images from standard input, but they are
569 not compatible with Microsoft's software and are not created by default.
570 See the documentation for --pipable flag of `wimlib-imagex capture' for
573 To better support incremental backups, added support for declaring an
574 image as a modified form of another image. See the documentation for
575 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
578 Added supported for "delta" WIMs. See the documentation for the
579 '--delta-from' option of `wimlib-imagex capture'.
581 The library support for managing split WIMs has been changed to support
582 other arrangements, such as delta WIMs, and be easier to use. This
583 change is visible in `wimlib-imagex', which also can now accept the
584 '--ref' option multiple times, and also now supports "delta" WIMs as
587 wimlib now preserves WIM integrity tables by default, even if
588 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
589 behavior of `wimlib-imagex' whenever the WIM being operated on contains
590 an integrity table and the '--check' option is not specified.
592 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
593 (when --compress is not specified). This provides the best compression
594 ratio by default, which is usually what is desired, at a cost of some
597 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
598 is the command as in `wimlib-imagex COMMAND'; for example, it can be
599 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
600 appropriate hard links are created in UNIX installations of
601 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
602 batch files that emulate this behavior are generated.
604 Security descriptors are now extracted correctly on Windows.
606 Fixed archiving DOS names in NTFS-3g capture mode.
608 The extraction code has been rewritten and it will now be easier to
609 support new features on all supported backends (currently Win32, UNIX,
610 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
611 now supported on all backends, not just UNIX.
613 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
614 than the WAIK itself.
616 wimlib_global_init() now, by default, attempts to acquire additional
617 privileges on Windows, so library clients need not do this.
619 This update bumps the shared library version number up to 9, since it is
620 not binary compatibible with previous releases.
623 Fixed bug in `wimlib-imagex export' that made it impossible to export an
624 image from a WIM that is readonly at the filesystem level.
626 Return error code rather than segfaulting when trying to list files from
627 a non-first part of a split WIM.
629 Joining a WIM will now preserve the RP_FIX and READONLY flags.
632 On Windows, paths given to wimlib-imagex are now treated case
635 Improved behavior regarding invalid filenames; in particular, on
636 Windows, wimlib-imagex will, when extracting, now omit (with an option
637 to override this default) filenames differing only in case, or filenames
638 containing characters not valid on Windows.
640 On Windows, wimlib now supports capturing and extracting long paths
641 (longer than the so-called MAX_PATH).
643 On Windows, `wimlib-imagex update' now acquires proper privileges when
644 running as an Administrator.
646 `wimlib-imagex update' will now complain if no image is specified when
647 trying to update a multi-image WIM.
649 `wimlib-imagex update' now supports specifying a single update command
650 directly on the command line using the --command option.
652 wimlib-imagex will now choose different units for progress messages,
653 depending on the amount of data that needs to be processed.
655 `wimlib-imagex append' will now generate a unique WIM image name if no
656 name is specified and the defaulted name already exists in the WIM.
658 wimlib now allows you to create unnamed WIM images, which can then only
659 be referred to by index.
661 wimlib now allows you to explicitly declare you want write access to a
662 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
665 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
668 Progress callbacks have been added to wimlib's wimlib_update_image()
671 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
672 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
675 NTFS-3g capture now only warns about two conditions previously treated
678 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
681 wimlib now correctly detects and returns an error when reading a WIM
682 image with a cyclic directory structure. (Fun fact: such a WIM will
683 crash Microsoft's software.)
686 Added new "extract" and "update" subcommands to wimlib-imagex, along
687 with associated APIs in the library. These commands are intended mainly
688 for Windows use but can be used on UNIX as well.
690 Many documentation improvements.
692 Fixed a bug in the Windows build where relative symbolic links were not
693 captured in reparse-point fixup mode.
695 Fixed a bug in the Windows build where file handles were left open to
696 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
698 Fixed a bug in the Windows build of wimlib-imagex where globbing
699 split-WIM parts could cause the program to crash.
701 Fixed a bug where the creation time of WIM images would be shown instead
702 of the last modification time.
704 With the Windows build it is now possible to restore a WIM containing
705 symbolic links as a non-Administrator; however you will receive warnings
706 about not being able to extract the symbolic links.
709 Capturing a WIM image should now be significantly faster in most cases
710 due to improved use of the operating system's cache and avoiding reading
711 files twice whenever possible.
713 The Windows build should now work on Windows XP.
715 The Windows build now supports capturing and restoring hidden,
716 compressed, sparse, and encrypted files.
718 The Windows build now supports capturing and applying WIM images from
719 filesystems other than NTFS (with some reduced functionality).
721 The Windows build now extracts short names correctly.
723 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
724 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
725 capture' and `wimlib-imagex apply'.
727 The performance of splitting and joining WIMs should be slightly
730 The LZX and XPRESS compression and decompression functions are now
731 exported from the library.
734 Improvements and bugfixes for the Windows build.
736 Added --strict-acls options.
738 Fixed the way that wimlib determines the order of images in the WIM.
741 Since wimlib can now be used on Windows, wimlib's implementation of
742 ImageX has been renamed to wimlib-imagex to avoid confusion with
743 Microsoft's implementation of ImageX, which would have the same file
744 name ("imagex.exe"). If you really don't like this you can pass the
745 --with-imagex-progname option to `configure' to choose a different name,
746 or even simply rename the binary yourself (but the former way will
747 configure the man pages to use the chosen name).
749 Various bugs fixed in the Windows build. Mainly to do with capturing
750 and restoring alternate data streams correctly in weird cases, and
751 requesting the correct privileges when opening files. Also added the
752 --noacls options to wimlib-imagex capture, append, and apply.
754 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
755 dynamically loaded, so this may make the library compatible with Windows
756 XP (however, there may still be other problems).
759 Added experimental support for native Windows builds. Binaries can be
760 downloaded from the SourceForge page.
762 --source-list option added to `imagex capture' and `imagex append'.
764 Better support for different character encodings.
767 Storing UNIX file owners, groups, and modes in WIM images is now
768 possible using `imagex capture' with the --unix-data flag.
770 Minor bug fixes and documentation fixes.
773 NTFS capture: Fixed capturing duplicate reparse points.
775 NTFS capture: Capture first unnamed stream if there are more than one
776 (print warning instead of error).
778 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
781 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
784 Update to work with ntfs-3g version 2013.1.13.
787 Fixed truncating file to shorter but non-zero length on read-write
790 Various code cleanups and minor documentation fixes.
793 LZX and XPRESS decompression have received some additional optimizations
794 and should now be even faster. (Although, they were already pretty
795 fast--- much faster than typical I/O speeds.)
797 Fixed a bug introduced in v1.2.1 that would cause a directory tree
798 containing hard links to be captured incorrectly in some cases.
801 By default, unmounting a read-write mounted WIM with 'imagex unmount
802 --commit' will now change the WIM in-place without needing to write the
803 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
806 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
807 for a response from the daemon servicing the mounted WIM. Instead,
808 every second 'imagex unmount' will check if the daemon is still alive,
809 and keep waiting if so, otherwise terminate with an error.
811 'imagex unmount --commit' on a read-write mounted WIM will now print
812 progress information regarding the writing of new or modified streams
813 the WIM, just like when capturing or appending a WIM.
815 A small change has been made to XPRESS compression and it should improve
816 the compression ratio slightly.
818 A change was made that may improve performance slightly when applying a
819 WIM image to a NTFS volume.
821 Microsoft has managed to introduce even more bugs into their software,
822 and now the WIMs for Windows 8 have incorrect (too low) reference counts
823 for some streams. This is unsafe because such streams can be removed
824 when they are in actuality still referenced in the WIM (perhaps by a
825 different image). wimlib will now work around this problem by fixing
826 the stream reference counts. This is only done when wimlib_delete_image() is
827 called ('imagex delete') or when wimlib_mount_image() is called with
828 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
829 requires reading the metadata for all images in the WIM, so this will
830 make these operations noticably slower on WIMs with multiple images.
832 Various other bugfixes.
835 Appending images to a WIM is now be done by default without re-building
836 the whole WIM. Use the --rebuild flag to get the old behavior (which
837 was to re-build the entire WIM when a new image is appended).
839 A new command `imagex optimize' is now available to manually re-build a
840 WIM that has wasted space due to repeated appends.
842 Progress information has been improved, and now arbitrary callback
843 functions can be used to show the progress of a WIM operation.
845 A possible bug with changing the bootable image of a WIM was fixed.
847 Some advisory locking is now done to prevent two processes from
848 modifying a WIM at the same time (but only in some cases). For example,
849 you cannot mount two images from a WIM read-write at the same time.
851 Some functions have been reorganized:
852 * wimlib_mount() renamed to wimlib_mount_image().
853 * wimlib_unmount() renamed to wimlib_unmount_image().
854 * wimlib_overwrite_xml_and_header() removed as
855 wimlib_overwrite() suffices now.
856 * wimlib_apply_image_to_ntfs_volume() removed as
857 wimlib_extract_image() suffices now.
858 * wimlib_add_image_from_ntfs_volume() removed as
859 * wimlib_add_image() suffices now.
861 Previously, the soname of libwim.so has been 0.0.0, despite many
862 interface changes. The soname is now updated to 1.0.0 and will now be
863 updated each release.
866 Resources will now be compressed using multiple threads by default.
867 (This applies to `imagex capture', `imagex append', and `imagex
870 Some performance improvements in mounted WIMs.
872 More progress information is shown when capturing a WIM.
875 Lots of minor fixes, code cleanups, and some documentation updates.
876 Nothing in particular is really noteworthy.
879 LZX and XPRESS compression improvements.
881 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
882 Link Bytes of the WIM.
885 Fixed bug when capturing NTFS file with multiple named data streams.
887 Internally, we are now using inode structures, even though these don't
888 appear literally in the WIM file. This simplifies some of the code
889 (mainly for WIM mounting) and likely fixed a few problems, although it
893 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
897 Enough changes to call it version 1.0.0!
899 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
900 to a NTFS volume, is now supported.
902 Hard links and symbolic links have much improved support. They are
903 supported for WIM capture, WIM application, and mounted WIMs (you can
904 even make them on read-write mounted WIMs).
906 Alternate data streams are now supported on mounted WIMs through an
907 xattr or a Windows-style stream interface. Also they are supported when
908 capturing a WIM from NTFS or applying a WIM to NTFS.
910 Split WIMs are better supported. You may now apply an image directly
911 from a split WIM, mount an image from a split WIM read-only, or export
912 an image from a split WIM.
914 Using a capture configuration file is now supported (but not fully yet).
916 SHA1 message digests are checked in more places, so we can make sure
917 applied and captured data is correct.
919 Man pages have been updated and consolidated.
922 Fixed segfault when unmounting read-only WIM.
925 Support for joining and splitting WIMs.
926 Also, security data is now preserved by default.
929 Can now build with older gcc and system headers, like on CentOS 5.
932 Fixed bug that made it impossible to overwrite files in read-write
936 Write byte-order mark before WIM XML data. (imagex.exe requires this to
