2 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
4 Reduced memory usage when exporting large numbers of WIM images.
6 Non UTF-8 locales are now detected correctly.
8 Addressed compiler warnings and enabled "silent" make rules by default.
10 Windows-specific updates:
11 Fixed a bug where duplicate backslashes could be generated in
12 link targets when extracting symbolic links and junctions.
14 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
15 work if their full path contained a space.
17 Fixed bugs related to scanning SMB filesystems.
19 Added warning message about known issue with WindowsApps folder.
21 Added instructions for building from source on Windows.
23 VSS support is no longer marked "experimental".
25 Added missing license file for libdivsufsort-lite.
28 Added experimental support for Windows VSS (Volume Shadow Copy Service).
29 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
30 create and use a temporary VSS snapshot when capturing a WIM image.
32 Implemented setting of Windows-specific XML information, such as
33 architecture, system root, and version details. This information is now
34 automatically set in newly captured WIM images, when appropriate.
36 Improved performance of directory tree scans on Windows.
38 On Windows, to improve capture performance, wimlib now sometimes opens
39 files by inode number rather than by path. This is enabled for
40 wimcapture and wimappend, but for now other applications have to opt-in.
42 The progress messages printed by wimlib-imagex while writing WIM files
43 have been slightly tweaked.
45 Progress information for directory tree scans now counts all hard links.
46 Also, on Windows "\\?\" is no longer stripped from the current path.
48 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
49 'wiminfo'. This option lets you assign values to elements in a WIM
50 file's XML document by name.
52 The wimlib_get_image_property() and wimlib_set_image_property() API
53 functions now support numerically indexed elements.
55 Fixed a bug where, on Windows, wimlib would change the security
56 descriptor of the target directory of an extraction even when the
57 '--no-acls' option was specified.
60 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
61 some Microsoft software would not correctly recognize data in the
64 Made some small improvements to the compression algorithms:
65 LZX compression ratio was slightly improved.
66 XPRESS compression ratio and speed was slightly improved.
67 LZMS compression speed was slightly improved.
69 Improved handling of WIM XML data. wimlib no longer drops unrecognized
70 elements when exporting images. In addition, two API functions were
71 added for better access to elements in the XML document:
72 wimlib_get_image_property() and wimlib_set_image_property().
74 Added support for (unsafe) in-place compaction of WIM files.
76 Improved performance of image export by reusing metadata resources
77 instead of always rebuilding and recompressing them.
79 Improved performance of wimlib_update_image() by delaying the update to
80 the WIM's XML document until a write is requested.
82 On Windows, the target of an extraction may now be a reparse point
83 (which will be dereferenced).
85 On Windows, wimlib now correctly restores non-Microsoft reparse points.
86 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
88 On Windows, wimlib now has improved performance when archiving files
89 from a filesystem backed by a WIM (a "WIMBoot" setup).
91 Several improvements to System Compression (compact mode) support:
93 wof.sys (or wofadk.sys) is now automatically attached to the
94 target volume if needed.
96 Compact-mode extractions now work correctly with wofadk.sys on
97 older versions of Windows.
99 For compatibility with the Windows bootloader, the requested
100 compression format now is overridden on certain files.
102 Other minor bugfixes.
105 This release primarily contains various minor bug fixes and
106 improvements, including:
108 Improved handling of deep directory structures.
110 Fixed a bug where on 32-bit systems, the library could enter an
111 infinite loop if a WIM file was malformed in a specific way.
113 Added a workaround for a case where libntfs-3g may report
114 duplicate streams in an NTFS file.
116 Windows symbolic links and junctions in mounted WIM images are
117 now automatically rewritten to be valid in the mounted location.
119 Reparse point fixes: correctly handle the "ReparseReserved"
120 field, and correctly handle "empty" (data-less) reparse points.
122 On Windows, wimlib now acquires SeManageVolumePrivilege, which
123 is needed to create externally backed files using the
126 Improved validation of filenames.
128 Improved LZMS decompression speed.
130 The configure script now honors alternate pkg-config settings.
132 Links have been updated to point to the new website.
134 In addition, experimental support has been added for compressing
135 extracted files using System Compression on Windows 10. This
136 functionality is available through the new '--compact' option to
137 'wimapply' and 'wimextract' as well as new library flags.
140 Fixed a bug in the LZX decompressor: malicious input data could cause
141 out of bounds writes to memory (since wimlib v1.2.2).
143 The output of the 'wiminfo' command now consolidates various boolean
144 flags (such as "Relative path junction") into a single line.
146 A file can now have both an unnamed data stream ("file contents") and a
147 reparse point stream. Such files can exist as a result of the use of
148 certain Windows features, such as offline storage, including "OneDrive".
149 wimlib will now store and restore both streams on Windows as well as in
150 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
152 On Windows, named data streams of encrypted files are no longer stored
153 twice in WIM archives.
155 On Windows, named data streams are now correctly extracted to existing
156 "readonly" directories. Before, an error would be reported.
158 On Windows, it is now possible to do a "WIMBoot mode" extraction with
159 non-standalone WIMs such as delta WIMs.
161 On Windows, when doing an extraction in "WIMBoot mode", files larger
162 than 4 gigabytes are now never extracted as externally backed. This
163 works around a bug in Microsoft's "WOF" driver.
165 The '--enable-verify-compression' configure option has been removed. If
166 you want to verify a WIM file, use the 'wimverify' program.
168 The way the "file count", "directory count", "total bytes", and "hard
169 link bytes" image statistics (stored in the WIM XML data) is calculated
170 has been slightly changed.
172 In mounted WIM images, the disk usage provided for each file (st_blocks)
173 is now the compressed size rather than the uncompressed size.
175 The performance of the NTFS-3g and Windows capture modes has been
178 On UNIX-like systems, symbolic links whose targets contain the backslash
179 character are now handled correctly (losslessly).
182 Improved the LZX compressor. It is now 15-20% faster than before and
183 provides a slightly better compression ratio.
185 Improved the LZMS compressor. It now provides a compression ratio
186 slightly better than WIMGAPI while still being faster and using slightly
189 The compression chunk size in solid resources, e.g. when capturing or
190 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
191 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
192 better compression ratio and is the same value that WIMGAPI uses. The
193 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
194 lower than WIMGAPI's memory usage, but if it is too much, it is still
195 possible to choose a lower value, e.g. with the '--solid-chunk-size'
196 option to wimlib-imagex.
198 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
199 accept the 'K', 'M', and 'G' suffixes.
201 Files are now sorted by name extension when creating a solid WIM file.
203 Fixed various issues related to capture/apply of EFS-encrypted files on
206 The file list printed by 'wimdir' is now sorted by the platform-specific
207 case sensitivity setting, rather than always case sensitively. This
208 also affects the library function wimlib_iterate_dir_tree().
210 On Windows, some error and warning messages have been improved.
213 The Windows binary distribution no longer contains third party DLLs.
214 These dependencies are instead compiled directly into the libwim DLL.
216 Added more fixes for wimlib on non-x86 architectures such as ARM.
218 Extracting files to a Windows PE in-memory filesystem no longer fails if
219 the target files do not yet exist.
221 Improved the performance of XPRESS compression and LZMS decompression.
223 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
224 It will automatically be faster on newer Intel and AMD processors.
226 Removed the --with-imagex-progname and --enable-more-assertions
230 Fix for very slow export from solid WIM / ESD files.
232 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
234 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
235 may use this to treat some types of errors as non-fatal.
237 The library now permits making in-memory changes to a WIMStruct backed
238 by a read-only WIM file.
240 Fixes for "WIMBoot" extraction mode (Windows only):
242 When not using the WOF driver, extraction no longer fails if the
243 disk containing the WIM file has too many partitions.
245 When matching patterns in [PrepopulateList], all hard links of
246 each file are now considered.
248 The system registry files are now automatically treated as being
249 in [PrepopulateList].
251 Added a hack to try to work around an intermittent bug in
252 Microsoft's WOF (Windows Overlay Filesystem) driver.
255 Made more improvements to the XPRESS, LZX, and LZMS compressors.
257 A number of improvements to the Windows port:
259 Fixes for setting short filenames.
261 Faster "WIMBoot" extraction.
263 Updated and slimmed down the dependent DLLs.
265 ACL inheritence bits are now restored.
267 Mandatory integrity labels are now backed up and restored.
269 Added a workaround for an issue where in rare cases, wimlib could create
270 a compressed data stream that could not be read correctly by Windows
271 after an extraction in "WIMBoot" mode.
274 Added file count progress data for
275 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
276 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
278 Added support for testing file exclusions via the user-provided
281 Some documentation improvements.
283 Made some clarifications to the license text in the COPYING file.
286 Made more improvements to the XPRESS, LZX, and LZMS compressors.
288 The default compression mode for wimcapture is now LZX compression in
289 its default mode, which is the same as '--compress=maximum'.
291 You can now specify an optional integer compression level to the
292 '--compress' option; e.g. '--compress=lzx:75'.
294 Made a minor change to the LZMS compressor and decompressor to fix an
295 incompatibility with the Microsoft implementation. In the unlikely
296 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
297 earlier and a checksum error is reported when extracting files from it
298 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
301 Added 'verify' subcommand to wimlib-imagex.
303 Notable library changes:
305 Custom compressor parameters have been removed from the library
306 in favor of the simpler level-based API.
308 Decompressor parameters have been removed entirely.
310 Library users can now specify a custom file for warning and
311 error messages to be sent to, rather than the default of
314 New progress messages:
315 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
316 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
318 New function: wimlib_verify_wim().
321 Improved compression, decompression, and extraction performance.
323 Improved compatibility with version 3584 WIM / ESD files:
324 - Add support for reading and writing multiple solid blocks per
325 archive, which WIMGAPI/DISM can create when appending an image.
326 - Correctly create solid blocks larger than 4 GiB.
328 'add' commands passed to wimupdate will now replace existing
329 nondirectory files by default. Use the --no-replace option to get the
332 The license for the library now contains an exception that allows using
333 it under the LGPL. See the COPYING file for details.
335 In reparse-point fixup mode (the default for capture), symbolic links
336 and junctions that point outside the tree being captured are no longer
337 excluded from capture.
339 Added support for "WIMBoot" capture and extraction. See the
340 documentation for the new '--wimboot' option to wimcapture and wimapply
341 for more information.
343 On UNIX-like systems, you can now backup and restore device nodes, named
344 pipes, and sockets. In addition, 32-bit user and group IDs are now
347 The way that UNIX data is stored in WIM files has been changed. If you
348 captured any WIMs with the --unix-data option, to upgrade them you'll
349 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
350 re-capture them with --unix-data using this version.
352 wimlib now understands tagged metadata items, such as object IDs, that
353 can be stored in WIM directory entries.
355 Removed the --hardlink and --symlink options to wimapply, since I don't
356 think they are too useful and they got in the way of improving the code.
358 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
360 The 'mkwinpeimg' script now supports writing the ISO image to standard
363 The <ARCH> element in WIM XML data is now exported correctly.
365 On Windows, sparse file attributes are no longer set on extracted files.
366 Oddly enough, this actually saves disk space in some cases.
368 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
369 supported. Mounting WIM images now always requires extended attribute
370 support. Use --without-fuse to disable support for mounting WIM images;
371 this will also disable the need for extended attribute support.
373 Configuring with --enable-ssse3-sha1 now works correctly.
375 The shared library version has been bumped up. The main
376 incompatibilities are:
378 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
379 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
382 - User-provided progress functions are now registered using a
383 separate function, wimlib_register_progress_function(). The
384 'progress_func' argument to many functions no longer exists.
386 - The return value from user-provided progress functions is now
389 - A context argument has been added to the prototype of
390 user-provided progress functions.
392 - 'struct wimlib_capture_config' has been removed. The library
393 now takes the path to the configuration file directly. This
394 affects wimlib_add_image(), wimlib_add_image_multisource(),
395 and wimlib_update_image(). However, a NULL value passed in
396 the argument retains the same meaning.
398 - Removed deprecated functions: some (de)compression functions,
399 wimlib_extract_files(), and wimlib_print_metadata().
401 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
402 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
403 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
405 - Removed some progress messages:
406 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
407 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
408 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
411 - Removed some error codes. Numbering stays the same.
413 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
414 WIMLIB_UNMOUNT_FLAG_FORCE.
416 - WIM paths passed to progress functions now have a leading
420 Case-insensitive comparisons of strings (e.g. filenames) containing
421 UTF-16 codepoints above 32767 are now done correctly.
423 Fixed build failure on Mac OS X.
425 wimunmount now provides the '--new-image' option to cause changes to a
426 read-write mounted image to be committed as a new image rather than as
427 an update of the mounted image. (The corresponding new library flag is
428 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
430 The LZMS ("recovery") compression chunk size, or "dictionary size", may
431 now be up to 1 GiB (1,073,741,824 bytes).
433 The performance of LZX ("maximum") and LZMS ("recovery") compression
434 with large chunk sizes has been slightly improved.
437 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
438 decompressed correctly.
440 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
441 occurred in an unlikely case, and due to validity checks it did not
442 affect successfully created archives.
444 Fixed a minor compatibility issue with the LZMS compressor and
445 decompressor. This is *not* the default compression type and was only
446 introduced in v1.6.0. In the unlikely event that you created an
447 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
448 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
451 Memory usage for LZMS and LZX compression has been decreased.
453 wimextract now allows wildcard characters in paths specified on the
454 command line. Also, the '--strict-wildcards' option has been removed
455 and replaced with the inverse option '--nullglob'. See the
456 documentation for wimextract for more details and changes.
458 The wimlib_extract_files() function is now considered deprecated in
459 favor of wimlib_extract_paths().
461 Fixed more permissions problems when extracting files on Windows.
463 A new '--no-attributes' option has been added to wimapply and
464 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
466 The default chunk size is now set correctly when changing the
467 compression type of a WIM, for example with 'wimoptimize'.
469 The '--metadata' option to wiminfo has been replaced with the
470 '--detailed' option to wimdir.
472 In relevant wimlib-imagex commands, '--solid' may now be used as an
473 alias for '--pack-streams'.
476 Support for extracting and updating the new version 3584 WIMs has been
477 added. These WIMs typically pack many streams ("files") together into a
478 single compressed resource, thereby saving space. This degrades the
479 performance of random access (such as that which occurs on a mounted
480 image), but optimizations have been implemented for extraction. These
481 new WIM files also typically use a new compression format (LZMS), which
482 is similar to LZMA and can offer a better compression ratio than LZX.
483 These new WIM files can be created using `wimcapture' with
484 the '--compress=lzms --pack-streams' options. Note: this new WIM format
485 is used by the Windows 8 web downloader, but important segments of the
486 raw '.esd' files are encrypted, so wimlib will not be able to extract
487 such files until they are first decrypted.
489 wimlib now supports extracting files and directories from a WIM image
490 based on a "listfile" that itself contains the list of paths to extract.
491 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
492 and for the library itself, the new APIs are wimlib_extract_pathlist()
493 and wimlib_extract_paths(). Path globs containing wildcard characters
496 For searching WIM files, wimlib now has configurable case sensitivity.
497 The default on Windows is still case-insensitive and the default on
498 UNIX-like systems is still case-sensitive, but this can be overridden
499 on either platform through flags to wimlib_global_init(). For
500 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
501 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
504 Support for compression chunk sizes greater than the default of 32768
505 bytes has been added. A larger chunk size typically results in a better
506 compression ratio. However, the MS implementation is seemingly not
507 compatible with all chunk sizes, especially for LZX compression, so the
508 defaults remain unchanged, with the exception of the new LZMS-compressed
509 WIMs, which use a larger chunk size by default.
511 The compression/decompression API exported by wimlib has been changed.
512 Now one set of functions handles all supported compression formats.
514 `wimcapture' and `wimappend' will now display the progress of scanning
515 the directory tree to capture, in addition to the progress of writing
516 data to the WIM. The '--verbose' option no longer does anything. The
517 library API change for this is the addition of several members to
518 `struct wimlib_progress_info_scan' available to progress callbacks.
520 `mkwinpeimg' now correctly handles the '--start-script' option when the
521 start script is not in the working directory.
523 Sequential extraction, previously requested by using
524 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
525 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
526 behavior (extract in file order).
529 The new LZX compressor added in v1.5.2 has been improved and is now
530 enabled by default, except when `wimcapture' or `wimappend' is run
531 *without* the '--compress' option, in which case the faster LZX
532 compressor is used (the same as before). This behavior is reasonably
533 consistent with ImageX which actually uses "fast" (XPRESS) compression
534 by default. In those cases, use '--compress=maximum' to explicitly
535 capture a WIM image using the new (slower but better) LZX compressor.
537 The '--compress-slow' option still exists to `wimlib-imagex optimize',
538 but its new behavior is to tweak the new LZX compressor even more to
539 produce an even better compression ratio at the cost of more time spent
542 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
543 which recompresses the WIM file using the specified compression TYPE.
544 The new library API function used for this is
545 wimlib_set_output_compression_type().
547 Added the wimlib_get_xml_data() function to allow library clients to
548 easily retrieve the raw XML data from a WIM file if needed.
550 Fixed a bug that could cause an error code to be incorrectly returned
551 when writing XML data containing a <WINDOWS> element.
553 Mounted WIM images will now correctly show the default file stream even
554 if appears in the alternate data stream entries of the corresponding WIM
558 Added a new experimental LZX compressor which can be enabled by passing
559 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
560 optimize'. (The latter is only applicable if the WIM is already
561 LZX-compressed and the '--recompress' option is also given.) The
562 experimental compressor is much slower but compresses the data slightly
563 more --- currently usually to within a fraction of a percent of the
564 results from WIMGAPI/ImageX.
566 A workaround has been added for compatibility with versions of WinPE
567 that interpret alternate data stream entries in the boot WIM
570 An alignment bug that caused a crash in the LZX decompressor on some
573 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
574 the WIM header when restoring the previous state of a WIM it failed to
577 Added a workaround to avoid an access denied error on Windows when
578 replacing a WIM file that another process has opened.
581 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
582 needed to be handled.
584 A bug in the interpretation of negative IMAGE indices in the
585 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
586 `wimlib-imagex append' has been fixed.
588 A workaround has been added to successfully apply security descriptors
589 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
590 2013.1.13 or earlier.
592 `wimlib-imagex capture' can now accept the '--delta-from' option
596 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
597 to standard output and applying images from standard input, but they are
598 not compatible with Microsoft's software and are not created by default.
599 See the documentation for --pipable flag of `wimlib-imagex capture' for
602 To better support incremental backups, added support for declaring an
603 image as a modified form of another image. See the documentation for
604 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
607 Added supported for "delta" WIMs. See the documentation for the
608 '--delta-from' option of `wimlib-imagex capture'.
610 The library support for managing split WIMs has been changed to support
611 other arrangements, such as delta WIMs, and be easier to use. This
612 change is visible in `wimlib-imagex', which also can now accept the
613 '--ref' option multiple times, and also now supports "delta" WIMs as
616 wimlib now preserves WIM integrity tables by default, even if
617 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
618 behavior of `wimlib-imagex' whenever the WIM being operated on contains
619 an integrity table and the '--check' option is not specified.
621 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
622 (when --compress is not specified). This provides the best compression
623 ratio by default, which is usually what is desired, at a cost of some
626 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
627 is the command as in `wimlib-imagex COMMAND'; for example, it can be
628 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
629 appropriate hard links are created in UNIX installations of
630 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
631 batch files that emulate this behavior are generated.
633 Security descriptors are now extracted correctly on Windows.
635 Fixed archiving DOS names in NTFS-3g capture mode.
637 The extraction code has been rewritten and it will now be easier to
638 support new features on all supported backends (currently Win32, UNIX,
639 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
640 now supported on all backends, not just UNIX.
642 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
643 than the WAIK itself.
645 wimlib_global_init() now, by default, attempts to acquire additional
646 privileges on Windows, so library clients need not do this.
648 This update bumps the shared library version number up to 9, since it is
649 not binary compatibible with previous releases.
652 Fixed bug in `wimlib-imagex export' that made it impossible to export an
653 image from a WIM that is readonly at the filesystem level.
655 Return error code rather than segfaulting when trying to list files from
656 a non-first part of a split WIM.
658 Joining a WIM will now preserve the RP_FIX and READONLY flags.
661 On Windows, paths given to wimlib-imagex are now treated case
664 Improved behavior regarding invalid filenames; in particular, on
665 Windows, wimlib-imagex will, when extracting, now omit (with an option
666 to override this default) filenames differing only in case, or filenames
667 containing characters not valid on Windows.
669 On Windows, wimlib now supports capturing and extracting long paths
670 (longer than the so-called MAX_PATH).
672 On Windows, `wimlib-imagex update' now acquires proper privileges when
673 running as an Administrator.
675 `wimlib-imagex update' will now complain if no image is specified when
676 trying to update a multi-image WIM.
678 `wimlib-imagex update' now supports specifying a single update command
679 directly on the command line using the --command option.
681 wimlib-imagex will now choose different units for progress messages,
682 depending on the amount of data that needs to be processed.
684 `wimlib-imagex append' will now generate a unique WIM image name if no
685 name is specified and the defaulted name already exists in the WIM.
687 wimlib now allows you to create unnamed WIM images, which can then only
688 be referred to by index.
690 wimlib now allows you to explicitly declare you want write access to a
691 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
694 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
697 Progress callbacks have been added to wimlib's wimlib_update_image()
700 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
701 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
704 NTFS-3g capture now only warns about two conditions previously treated
707 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
710 wimlib now correctly detects and returns an error when reading a WIM
711 image with a cyclic directory structure. (Fun fact: such a WIM will
712 crash Microsoft's software.)
715 Added new "extract" and "update" subcommands to wimlib-imagex, along
716 with associated APIs in the library. These commands are intended mainly
717 for Windows use but can be used on UNIX as well.
719 Many documentation improvements.
721 Fixed a bug in the Windows build where relative symbolic links were not
722 captured in reparse-point fixup mode.
724 Fixed a bug in the Windows build where file handles were left open to
725 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
727 Fixed a bug in the Windows build of wimlib-imagex where globbing
728 split-WIM parts could cause the program to crash.
730 Fixed a bug where the creation time of WIM images would be shown instead
731 of the last modification time.
733 With the Windows build it is now possible to restore a WIM containing
734 symbolic links as a non-Administrator; however you will receive warnings
735 about not being able to extract the symbolic links.
738 Capturing a WIM image should now be significantly faster in most cases
739 due to improved use of the operating system's cache and avoiding reading
740 files twice whenever possible.
742 The Windows build should now work on Windows XP.
744 The Windows build now supports capturing and restoring hidden,
745 compressed, sparse, and encrypted files.
747 The Windows build now supports capturing and applying WIM images from
748 filesystems other than NTFS (with some reduced functionality).
750 The Windows build now extracts short names correctly.
752 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
753 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
754 capture' and `wimlib-imagex apply'.
756 The performance of splitting and joining WIMs should be slightly
759 The LZX and XPRESS compression and decompression functions are now
760 exported from the library.
763 Improvements and bugfixes for the Windows build.
765 Added --strict-acls options.
767 Fixed the way that wimlib determines the order of images in the WIM.
770 Since wimlib can now be used on Windows, wimlib's implementation of
771 ImageX has been renamed to wimlib-imagex to avoid confusion with
772 Microsoft's implementation of ImageX, which would have the same file
773 name ("imagex.exe"). If you really don't like this you can pass the
774 --with-imagex-progname option to `configure' to choose a different name,
775 or even simply rename the binary yourself (but the former way will
776 configure the man pages to use the chosen name).
778 Various bugs fixed in the Windows build. Mainly to do with capturing
779 and restoring alternate data streams correctly in weird cases, and
780 requesting the correct privileges when opening files. Also added the
781 --noacls options to wimlib-imagex capture, append, and apply.
783 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
784 dynamically loaded, so this may make the library compatible with Windows
785 XP (however, there may still be other problems).
788 Added experimental support for native Windows builds. Binaries can be
789 downloaded from the SourceForge page.
791 --source-list option added to `imagex capture' and `imagex append'.
793 Better support for different character encodings.
796 Storing UNIX file owners, groups, and modes in WIM images is now
797 possible using `imagex capture' with the --unix-data flag.
799 Minor bug fixes and documentation fixes.
802 NTFS capture: Fixed capturing duplicate reparse points.
804 NTFS capture: Capture first unnamed stream if there are more than one
805 (print warning instead of error).
807 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
810 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
813 Update to work with ntfs-3g version 2013.1.13.
816 Fixed truncating file to shorter but non-zero length on read-write
819 Various code cleanups and minor documentation fixes.
822 LZX and XPRESS decompression have received some additional optimizations
823 and should now be even faster. (Although, they were already pretty
824 fast--- much faster than typical I/O speeds.)
826 Fixed a bug introduced in v1.2.1 that would cause a directory tree
827 containing hard links to be captured incorrectly in some cases.
830 By default, unmounting a read-write mounted WIM with 'imagex unmount
831 --commit' will now change the WIM in-place without needing to write the
832 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
835 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
836 for a response from the daemon servicing the mounted WIM. Instead,
837 every second 'imagex unmount' will check if the daemon is still alive,
838 and keep waiting if so, otherwise terminate with an error.
840 'imagex unmount --commit' on a read-write mounted WIM will now print
841 progress information regarding the writing of new or modified streams
842 the WIM, just like when capturing or appending a WIM.
844 A small change has been made to XPRESS compression and it should improve
845 the compression ratio slightly.
847 A change was made that may improve performance slightly when applying a
848 WIM image to a NTFS volume.
850 Microsoft has managed to introduce even more bugs into their software,
851 and now the WIMs for Windows 8 have incorrect (too low) reference counts
852 for some streams. This is unsafe because such streams can be removed
853 when they are in actuality still referenced in the WIM (perhaps by a
854 different image). wimlib will now work around this problem by fixing
855 the stream reference counts. This is only done when wimlib_delete_image() is
856 called ('imagex delete') or when wimlib_mount_image() is called with
857 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
858 requires reading the metadata for all images in the WIM, so this will
859 make these operations noticably slower on WIMs with multiple images.
861 Various other bugfixes.
864 Appending images to a WIM is now be done by default without re-building
865 the whole WIM. Use the --rebuild flag to get the old behavior (which
866 was to re-build the entire WIM when a new image is appended).
868 A new command `imagex optimize' is now available to manually re-build a
869 WIM that has wasted space due to repeated appends.
871 Progress information has been improved, and now arbitrary callback
872 functions can be used to show the progress of a WIM operation.
874 A possible bug with changing the bootable image of a WIM was fixed.
876 Some advisory locking is now done to prevent two processes from
877 modifying a WIM at the same time (but only in some cases). For example,
878 you cannot mount two images from a WIM read-write at the same time.
880 Some functions have been reorganized:
881 * wimlib_mount() renamed to wimlib_mount_image().
882 * wimlib_unmount() renamed to wimlib_unmount_image().
883 * wimlib_overwrite_xml_and_header() removed as
884 wimlib_overwrite() suffices now.
885 * wimlib_apply_image_to_ntfs_volume() removed as
886 wimlib_extract_image() suffices now.
887 * wimlib_add_image_from_ntfs_volume() removed as
888 * wimlib_add_image() suffices now.
890 Previously, the soname of libwim.so has been 0.0.0, despite many
891 interface changes. The soname is now updated to 1.0.0 and will now be
892 updated each release.
895 Resources will now be compressed using multiple threads by default.
896 (This applies to `imagex capture', `imagex append', and `imagex
899 Some performance improvements in mounted WIMs.
901 More progress information is shown when capturing a WIM.
904 Lots of minor fixes, code cleanups, and some documentation updates.
905 Nothing in particular is really noteworthy.
908 LZX and XPRESS compression improvements.
910 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
911 Link Bytes of the WIM.
914 Fixed bug when capturing NTFS file with multiple named data streams.
916 Internally, we are now using inode structures, even though these don't
917 appear literally in the WIM file. This simplifies some of the code
918 (mainly for WIM mounting) and likely fixed a few problems, although it
922 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
926 Enough changes to call it version 1.0.0!
928 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
929 to a NTFS volume, is now supported.
931 Hard links and symbolic links have much improved support. They are
932 supported for WIM capture, WIM application, and mounted WIMs (you can
933 even make them on read-write mounted WIMs).
935 Alternate data streams are now supported on mounted WIMs through an
936 xattr or a Windows-style stream interface. Also they are supported when
937 capturing a WIM from NTFS or applying a WIM to NTFS.
939 Split WIMs are better supported. You may now apply an image directly
940 from a split WIM, mount an image from a split WIM read-only, or export
941 an image from a split WIM.
943 Using a capture configuration file is now supported (but not fully yet).
945 SHA1 message digests are checked in more places, so we can make sure
946 applied and captured data is correct.
948 Man pages have been updated and consolidated.
951 Fixed segfault when unmounting read-only WIM.
954 Support for joining and splitting WIMs.
955 Also, security data is now preserved by default.
958 Can now build with older gcc and system headers, like on CentOS 5.
961 Fixed bug that made it impossible to overwrite files in read-write
965 Write byte-order mark before WIM XML data. (imagex.exe requires this to
