2 On UNIX, wimlib can now overwrite readonly files when extracting.
4 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
5 NTFS permissions") set on some existing directories after extraction.
7 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
8 driver is not loaded, wimlib can now correctly register a new WIM file
9 with the target volume when the target volume previously had had WIM
12 Added a new testing program.
14 Clarified the main license text and updated public domain dedications
15 for certain files to be more thorough.
18 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
20 Reduced memory usage when exporting large numbers of WIM images.
22 Non UTF-8 locales are now detected correctly.
24 Addressed compiler warnings and enabled "silent" make rules by default.
26 Windows-specific updates:
27 Fixed a bug where duplicate backslashes could be generated in
28 link targets when extracting symbolic links and junctions.
30 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
31 work if their full path contained a space.
33 Fixed bugs related to scanning SMB filesystems.
35 Added warning message about known issue with WindowsApps folder.
37 Added instructions for building from source on Windows.
39 VSS support is no longer marked "experimental".
41 Added missing license file for libdivsufsort-lite.
44 Added experimental support for Windows VSS (Volume Shadow Copy Service).
45 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
46 create and use a temporary VSS snapshot when capturing a WIM image.
48 Implemented setting of Windows-specific XML information, such as
49 architecture, system root, and version details. This information is now
50 automatically set in newly captured WIM images, when appropriate.
52 Improved performance of directory tree scans on Windows.
54 On Windows, to improve capture performance, wimlib now sometimes opens
55 files by inode number rather than by path. This is enabled for
56 wimcapture and wimappend, but for now other applications have to opt-in.
58 The progress messages printed by wimlib-imagex while writing WIM files
59 have been slightly tweaked.
61 Progress information for directory tree scans now counts all hard links.
62 Also, on Windows "\\?\" is no longer stripped from the current path.
64 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
65 'wiminfo'. This option lets you assign values to elements in a WIM
66 file's XML document by name.
68 The wimlib_get_image_property() and wimlib_set_image_property() API
69 functions now support numerically indexed elements.
71 Fixed a bug where, on Windows, wimlib would change the security
72 descriptor of the target directory of an extraction even when the
73 '--no-acls' option was specified.
76 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
77 some Microsoft software would not correctly recognize data in the
80 Made some small improvements to the compression algorithms:
81 LZX compression ratio was slightly improved.
82 XPRESS compression ratio and speed was slightly improved.
83 LZMS compression speed was slightly improved.
85 Improved handling of WIM XML data. wimlib no longer drops unrecognized
86 elements when exporting images. In addition, two API functions were
87 added for better access to elements in the XML document:
88 wimlib_get_image_property() and wimlib_set_image_property().
90 Added support for (unsafe) in-place compaction of WIM files.
92 Improved performance of image export by reusing metadata resources
93 instead of always rebuilding and recompressing them.
95 Improved performance of wimlib_update_image() by delaying the update to
96 the WIM's XML document until a write is requested.
98 On Windows, the target of an extraction may now be a reparse point
99 (which will be dereferenced).
101 On Windows, wimlib now correctly restores non-Microsoft reparse points.
102 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
104 On Windows, wimlib now has improved performance when archiving files
105 from a filesystem backed by a WIM (a "WIMBoot" setup).
107 Several improvements to System Compression (compact mode) support:
109 wof.sys (or wofadk.sys) is now automatically attached to the
110 target volume if needed.
112 Compact-mode extractions now work correctly with wofadk.sys on
113 older versions of Windows.
115 For compatibility with the Windows bootloader, the requested
116 compression format now is overridden on certain files.
118 Other minor bugfixes.
121 This release primarily contains various minor bug fixes and
122 improvements, including:
124 Improved handling of deep directory structures.
126 Fixed a bug where on 32-bit systems, the library could enter an
127 infinite loop if a WIM file was malformed in a specific way.
129 Added a workaround for a case where libntfs-3g may report
130 duplicate streams in an NTFS file.
132 Windows symbolic links and junctions in mounted WIM images are
133 now automatically rewritten to be valid in the mounted location.
135 Reparse point fixes: correctly handle the "ReparseReserved"
136 field, and correctly handle "empty" (data-less) reparse points.
138 On Windows, wimlib now acquires SeManageVolumePrivilege, which
139 is needed to create externally backed files using the
142 Improved validation of filenames.
144 Improved LZMS decompression speed.
146 The configure script now honors alternate pkg-config settings.
148 Links have been updated to point to the new website.
150 In addition, experimental support has been added for compressing
151 extracted files using System Compression on Windows 10. This
152 functionality is available through the new '--compact' option to
153 'wimapply' and 'wimextract' as well as new library flags.
156 Fixed a bug in the LZX decompressor: malicious input data could cause
157 out of bounds writes to memory (since wimlib v1.2.2).
159 The output of the 'wiminfo' command now consolidates various boolean
160 flags (such as "Relative path junction") into a single line.
162 A file can now have both an unnamed data stream ("file contents") and a
163 reparse point stream. Such files can exist as a result of the use of
164 certain Windows features, such as offline storage, including "OneDrive".
165 wimlib will now store and restore both streams on Windows as well as in
166 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
168 On Windows, named data streams of encrypted files are no longer stored
169 twice in WIM archives.
171 On Windows, named data streams are now correctly extracted to existing
172 "readonly" directories. Before, an error would be reported.
174 On Windows, it is now possible to do a "WIMBoot mode" extraction with
175 non-standalone WIMs such as delta WIMs.
177 On Windows, when doing an extraction in "WIMBoot mode", files larger
178 than 4 gigabytes are now never extracted as externally backed. This
179 works around a bug in Microsoft's "WOF" driver.
181 The '--enable-verify-compression' configure option has been removed. If
182 you want to verify a WIM file, use the 'wimverify' program.
184 The way the "file count", "directory count", "total bytes", and "hard
185 link bytes" image statistics (stored in the WIM XML data) is calculated
186 has been slightly changed.
188 In mounted WIM images, the disk usage provided for each file (st_blocks)
189 is now the compressed size rather than the uncompressed size.
191 The performance of the NTFS-3g and Windows capture modes has been
194 On UNIX-like systems, symbolic links whose targets contain the backslash
195 character are now handled correctly (losslessly).
198 Improved the LZX compressor. It is now 15-20% faster than before and
199 provides a slightly better compression ratio.
201 Improved the LZMS compressor. It now provides a compression ratio
202 slightly better than WIMGAPI while still being faster and using slightly
205 The compression chunk size in solid resources, e.g. when capturing or
206 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
207 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
208 better compression ratio and is the same value that WIMGAPI uses. The
209 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
210 lower than WIMGAPI's memory usage, but if it is too much, it is still
211 possible to choose a lower value, e.g. with the '--solid-chunk-size'
212 option to wimlib-imagex.
214 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
215 accept the 'K', 'M', and 'G' suffixes.
217 Files are now sorted by name extension when creating a solid WIM file.
219 Fixed various issues related to capture/apply of EFS-encrypted files on
222 The file list printed by 'wimdir' is now sorted by the platform-specific
223 case sensitivity setting, rather than always case sensitively. This
224 also affects the library function wimlib_iterate_dir_tree().
226 On Windows, some error and warning messages have been improved.
229 The Windows binary distribution no longer contains third party DLLs.
230 These dependencies are instead compiled directly into the libwim DLL.
232 Added more fixes for wimlib on non-x86 architectures such as ARM.
234 Extracting files to a Windows PE in-memory filesystem no longer fails if
235 the target files do not yet exist.
237 Improved the performance of XPRESS compression and LZMS decompression.
239 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
240 It will automatically be faster on newer Intel and AMD processors.
242 Removed the --with-imagex-progname and --enable-more-assertions
246 Fix for very slow export from solid WIM / ESD files.
248 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
250 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
251 may use this to treat some types of errors as non-fatal.
253 The library now permits making in-memory changes to a WIMStruct backed
254 by a read-only WIM file.
256 Fixes for "WIMBoot" extraction mode (Windows only):
258 When not using the WOF driver, extraction no longer fails if the
259 disk containing the WIM file has too many partitions.
261 When matching patterns in [PrepopulateList], all hard links of
262 each file are now considered.
264 The system registry files are now automatically treated as being
265 in [PrepopulateList].
267 Added a hack to try to work around an intermittent bug in
268 Microsoft's WOF (Windows Overlay Filesystem) driver.
271 Made more improvements to the XPRESS, LZX, and LZMS compressors.
273 A number of improvements to the Windows port:
275 Fixes for setting short filenames.
277 Faster "WIMBoot" extraction.
279 Updated and slimmed down the dependent DLLs.
281 ACL inheritence bits are now restored.
283 Mandatory integrity labels are now backed up and restored.
285 Added a workaround for an issue where in rare cases, wimlib could create
286 a compressed data stream that could not be read correctly by Windows
287 after an extraction in "WIMBoot" mode.
290 Added file count progress data for
291 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
292 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
294 Added support for testing file exclusions via the user-provided
297 Some documentation improvements.
299 Made some clarifications to the license text in the COPYING file.
302 Made more improvements to the XPRESS, LZX, and LZMS compressors.
304 The default compression mode for wimcapture is now LZX compression in
305 its default mode, which is the same as '--compress=maximum'.
307 You can now specify an optional integer compression level to the
308 '--compress' option; e.g. '--compress=lzx:75'.
310 Made a minor change to the LZMS compressor and decompressor to fix an
311 incompatibility with the Microsoft implementation. In the unlikely
312 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
313 earlier and a checksum error is reported when extracting files from it
314 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
317 Added 'verify' subcommand to wimlib-imagex.
319 Notable library changes:
321 Custom compressor parameters have been removed from the library
322 in favor of the simpler level-based API.
324 Decompressor parameters have been removed entirely.
326 Library users can now specify a custom file for warning and
327 error messages to be sent to, rather than the default of
330 New progress messages:
331 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
332 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
334 New function: wimlib_verify_wim().
337 Improved compression, decompression, and extraction performance.
339 Improved compatibility with version 3584 WIM / ESD files:
340 - Add support for reading and writing multiple solid blocks per
341 archive, which WIMGAPI/DISM can create when appending an image.
342 - Correctly create solid blocks larger than 4 GiB.
344 'add' commands passed to wimupdate will now replace existing
345 nondirectory files by default. Use the --no-replace option to get the
348 The license for the library now contains an exception that allows using
349 it under the LGPL. See the COPYING file for details.
351 In reparse-point fixup mode (the default for capture), symbolic links
352 and junctions that point outside the tree being captured are no longer
353 excluded from capture.
355 Added support for "WIMBoot" capture and extraction. See the
356 documentation for the new '--wimboot' option to wimcapture and wimapply
357 for more information.
359 On UNIX-like systems, you can now backup and restore device nodes, named
360 pipes, and sockets. In addition, 32-bit user and group IDs are now
363 The way that UNIX data is stored in WIM files has been changed. If you
364 captured any WIMs with the --unix-data option, to upgrade them you'll
365 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
366 re-capture them with --unix-data using this version.
368 wimlib now understands tagged metadata items, such as object IDs, that
369 can be stored in WIM directory entries.
371 Removed the --hardlink and --symlink options to wimapply, since I don't
372 think they are too useful and they got in the way of improving the code.
374 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
376 The 'mkwinpeimg' script now supports writing the ISO image to standard
379 The <ARCH> element in WIM XML data is now exported correctly.
381 On Windows, sparse file attributes are no longer set on extracted files.
382 Oddly enough, this actually saves disk space in some cases.
384 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
385 supported. Mounting WIM images now always requires extended attribute
386 support. Use --without-fuse to disable support for mounting WIM images;
387 this will also disable the need for extended attribute support.
389 Configuring with --enable-ssse3-sha1 now works correctly.
391 The shared library version has been bumped up. The main
392 incompatibilities are:
394 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
395 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
398 - User-provided progress functions are now registered using a
399 separate function, wimlib_register_progress_function(). The
400 'progress_func' argument to many functions no longer exists.
402 - The return value from user-provided progress functions is now
405 - A context argument has been added to the prototype of
406 user-provided progress functions.
408 - 'struct wimlib_capture_config' has been removed. The library
409 now takes the path to the configuration file directly. This
410 affects wimlib_add_image(), wimlib_add_image_multisource(),
411 and wimlib_update_image(). However, a NULL value passed in
412 the argument retains the same meaning.
414 - Removed deprecated functions: some (de)compression functions,
415 wimlib_extract_files(), and wimlib_print_metadata().
417 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
418 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
419 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
421 - Removed some progress messages:
422 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
423 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
424 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
427 - Removed some error codes. Numbering stays the same.
429 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
430 WIMLIB_UNMOUNT_FLAG_FORCE.
432 - WIM paths passed to progress functions now have a leading
436 Case-insensitive comparisons of strings (e.g. filenames) containing
437 UTF-16 codepoints above 32767 are now done correctly.
439 Fixed build failure on Mac OS X.
441 wimunmount now provides the '--new-image' option to cause changes to a
442 read-write mounted image to be committed as a new image rather than as
443 an update of the mounted image. (The corresponding new library flag is
444 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
446 The LZMS ("recovery") compression chunk size, or "dictionary size", may
447 now be up to 1 GiB (1,073,741,824 bytes).
449 The performance of LZX ("maximum") and LZMS ("recovery") compression
450 with large chunk sizes has been slightly improved.
453 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
454 decompressed correctly.
456 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
457 occurred in an unlikely case, and due to validity checks it did not
458 affect successfully created archives.
460 Fixed a minor compatibility issue with the LZMS compressor and
461 decompressor. This is *not* the default compression type and was only
462 introduced in v1.6.0. In the unlikely event that you created an
463 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
464 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
467 Memory usage for LZMS and LZX compression has been decreased.
469 wimextract now allows wildcard characters in paths specified on the
470 command line. Also, the '--strict-wildcards' option has been removed
471 and replaced with the inverse option '--nullglob'. See the
472 documentation for wimextract for more details and changes.
474 The wimlib_extract_files() function is now considered deprecated in
475 favor of wimlib_extract_paths().
477 Fixed more permissions problems when extracting files on Windows.
479 A new '--no-attributes' option has been added to wimapply and
480 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
482 The default chunk size is now set correctly when changing the
483 compression type of a WIM, for example with 'wimoptimize'.
485 The '--metadata' option to wiminfo has been replaced with the
486 '--detailed' option to wimdir.
488 In relevant wimlib-imagex commands, '--solid' may now be used as an
489 alias for '--pack-streams'.
492 Support for extracting and updating the new version 3584 WIMs has been
493 added. These WIMs typically pack many streams ("files") together into a
494 single compressed resource, thereby saving space. This degrades the
495 performance of random access (such as that which occurs on a mounted
496 image), but optimizations have been implemented for extraction. These
497 new WIM files also typically use a new compression format (LZMS), which
498 is similar to LZMA and can offer a better compression ratio than LZX.
499 These new WIM files can be created using `wimcapture' with
500 the '--compress=lzms --pack-streams' options. Note: this new WIM format
501 is used by the Windows 8 web downloader, but important segments of the
502 raw '.esd' files are encrypted, so wimlib will not be able to extract
503 such files until they are first decrypted.
505 wimlib now supports extracting files and directories from a WIM image
506 based on a "listfile" that itself contains the list of paths to extract.
507 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
508 and for the library itself, the new APIs are wimlib_extract_pathlist()
509 and wimlib_extract_paths(). Path globs containing wildcard characters
512 For searching WIM files, wimlib now has configurable case sensitivity.
513 The default on Windows is still case-insensitive and the default on
514 UNIX-like systems is still case-sensitive, but this can be overridden
515 on either platform through flags to wimlib_global_init(). For
516 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
517 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
520 Support for compression chunk sizes greater than the default of 32768
521 bytes has been added. A larger chunk size typically results in a better
522 compression ratio. However, the MS implementation is seemingly not
523 compatible with all chunk sizes, especially for LZX compression, so the
524 defaults remain unchanged, with the exception of the new LZMS-compressed
525 WIMs, which use a larger chunk size by default.
527 The compression/decompression API exported by wimlib has been changed.
528 Now one set of functions handles all supported compression formats.
530 `wimcapture' and `wimappend' will now display the progress of scanning
531 the directory tree to capture, in addition to the progress of writing
532 data to the WIM. The '--verbose' option no longer does anything. The
533 library API change for this is the addition of several members to
534 `struct wimlib_progress_info_scan' available to progress callbacks.
536 `mkwinpeimg' now correctly handles the '--start-script' option when the
537 start script is not in the working directory.
539 Sequential extraction, previously requested by using
540 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
541 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
542 behavior (extract in file order).
545 The new LZX compressor added in v1.5.2 has been improved and is now
546 enabled by default, except when `wimcapture' or `wimappend' is run
547 *without* the '--compress' option, in which case the faster LZX
548 compressor is used (the same as before). This behavior is reasonably
549 consistent with ImageX which actually uses "fast" (XPRESS) compression
550 by default. In those cases, use '--compress=maximum' to explicitly
551 capture a WIM image using the new (slower but better) LZX compressor.
553 The '--compress-slow' option still exists to `wimlib-imagex optimize',
554 but its new behavior is to tweak the new LZX compressor even more to
555 produce an even better compression ratio at the cost of more time spent
558 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
559 which recompresses the WIM file using the specified compression TYPE.
560 The new library API function used for this is
561 wimlib_set_output_compression_type().
563 Added the wimlib_get_xml_data() function to allow library clients to
564 easily retrieve the raw XML data from a WIM file if needed.
566 Fixed a bug that could cause an error code to be incorrectly returned
567 when writing XML data containing a <WINDOWS> element.
569 Mounted WIM images will now correctly show the default file stream even
570 if appears in the alternate data stream entries of the corresponding WIM
574 Added a new experimental LZX compressor which can be enabled by passing
575 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
576 optimize'. (The latter is only applicable if the WIM is already
577 LZX-compressed and the '--recompress' option is also given.) The
578 experimental compressor is much slower but compresses the data slightly
579 more --- currently usually to within a fraction of a percent of the
580 results from WIMGAPI/ImageX.
582 A workaround has been added for compatibility with versions of WinPE
583 that interpret alternate data stream entries in the boot WIM
586 An alignment bug that caused a crash in the LZX decompressor on some
589 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
590 the WIM header when restoring the previous state of a WIM it failed to
593 Added a workaround to avoid an access denied error on Windows when
594 replacing a WIM file that another process has opened.
597 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
598 needed to be handled.
600 A bug in the interpretation of negative IMAGE indices in the
601 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
602 `wimlib-imagex append' has been fixed.
604 A workaround has been added to successfully apply security descriptors
605 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
606 2013.1.13 or earlier.
608 `wimlib-imagex capture' can now accept the '--delta-from' option
612 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
613 to standard output and applying images from standard input, but they are
614 not compatible with Microsoft's software and are not created by default.
615 See the documentation for --pipable flag of `wimlib-imagex capture' for
618 To better support incremental backups, added support for declaring an
619 image as a modified form of another image. See the documentation for
620 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
623 Added supported for "delta" WIMs. See the documentation for the
624 '--delta-from' option of `wimlib-imagex capture'.
626 The library support for managing split WIMs has been changed to support
627 other arrangements, such as delta WIMs, and be easier to use. This
628 change is visible in `wimlib-imagex', which also can now accept the
629 '--ref' option multiple times, and also now supports "delta" WIMs as
632 wimlib now preserves WIM integrity tables by default, even if
633 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
634 behavior of `wimlib-imagex' whenever the WIM being operated on contains
635 an integrity table and the '--check' option is not specified.
637 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
638 (when --compress is not specified). This provides the best compression
639 ratio by default, which is usually what is desired, at a cost of some
642 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
643 is the command as in `wimlib-imagex COMMAND'; for example, it can be
644 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
645 appropriate hard links are created in UNIX installations of
646 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
647 batch files that emulate this behavior are generated.
649 Security descriptors are now extracted correctly on Windows.
651 Fixed archiving DOS names in NTFS-3g capture mode.
653 The extraction code has been rewritten and it will now be easier to
654 support new features on all supported backends (currently Win32, UNIX,
655 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
656 now supported on all backends, not just UNIX.
658 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
659 than the WAIK itself.
661 wimlib_global_init() now, by default, attempts to acquire additional
662 privileges on Windows, so library clients need not do this.
664 This update bumps the shared library version number up to 9, since it is
665 not binary compatibible with previous releases.
668 Fixed bug in `wimlib-imagex export' that made it impossible to export an
669 image from a WIM that is readonly at the filesystem level.
671 Return error code rather than segfaulting when trying to list files from
672 a non-first part of a split WIM.
674 Joining a WIM will now preserve the RP_FIX and READONLY flags.
677 On Windows, paths given to wimlib-imagex are now treated case
680 Improved behavior regarding invalid filenames; in particular, on
681 Windows, wimlib-imagex will, when extracting, now omit (with an option
682 to override this default) filenames differing only in case, or filenames
683 containing characters not valid on Windows.
685 On Windows, wimlib now supports capturing and extracting long paths
686 (longer than the so-called MAX_PATH).
688 On Windows, `wimlib-imagex update' now acquires proper privileges when
689 running as an Administrator.
691 `wimlib-imagex update' will now complain if no image is specified when
692 trying to update a multi-image WIM.
694 `wimlib-imagex update' now supports specifying a single update command
695 directly on the command line using the --command option.
697 wimlib-imagex will now choose different units for progress messages,
698 depending on the amount of data that needs to be processed.
700 `wimlib-imagex append' will now generate a unique WIM image name if no
701 name is specified and the defaulted name already exists in the WIM.
703 wimlib now allows you to create unnamed WIM images, which can then only
704 be referred to by index.
706 wimlib now allows you to explicitly declare you want write access to a
707 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
710 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
713 Progress callbacks have been added to wimlib's wimlib_update_image()
716 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
717 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
720 NTFS-3g capture now only warns about two conditions previously treated
723 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
726 wimlib now correctly detects and returns an error when reading a WIM
727 image with a cyclic directory structure. (Fun fact: such a WIM will
728 crash Microsoft's software.)
731 Added new "extract" and "update" subcommands to wimlib-imagex, along
732 with associated APIs in the library. These commands are intended mainly
733 for Windows use but can be used on UNIX as well.
735 Many documentation improvements.
737 Fixed a bug in the Windows build where relative symbolic links were not
738 captured in reparse-point fixup mode.
740 Fixed a bug in the Windows build where file handles were left open to
741 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
743 Fixed a bug in the Windows build of wimlib-imagex where globbing
744 split-WIM parts could cause the program to crash.
746 Fixed a bug where the creation time of WIM images would be shown instead
747 of the last modification time.
749 With the Windows build it is now possible to restore a WIM containing
750 symbolic links as a non-Administrator; however you will receive warnings
751 about not being able to extract the symbolic links.
754 Capturing a WIM image should now be significantly faster in most cases
755 due to improved use of the operating system's cache and avoiding reading
756 files twice whenever possible.
758 The Windows build should now work on Windows XP.
760 The Windows build now supports capturing and restoring hidden,
761 compressed, sparse, and encrypted files.
763 The Windows build now supports capturing and applying WIM images from
764 filesystems other than NTFS (with some reduced functionality).
766 The Windows build now extracts short names correctly.
768 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
769 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
770 capture' and `wimlib-imagex apply'.
772 The performance of splitting and joining WIMs should be slightly
775 The LZX and XPRESS compression and decompression functions are now
776 exported from the library.
779 Improvements and bugfixes for the Windows build.
781 Added --strict-acls options.
783 Fixed the way that wimlib determines the order of images in the WIM.
786 Since wimlib can now be used on Windows, wimlib's implementation of
787 ImageX has been renamed to wimlib-imagex to avoid confusion with
788 Microsoft's implementation of ImageX, which would have the same file
789 name ("imagex.exe"). If you really don't like this you can pass the
790 --with-imagex-progname option to `configure' to choose a different name,
791 or even simply rename the binary yourself (but the former way will
792 configure the man pages to use the chosen name).
794 Various bugs fixed in the Windows build. Mainly to do with capturing
795 and restoring alternate data streams correctly in weird cases, and
796 requesting the correct privileges when opening files. Also added the
797 --noacls options to wimlib-imagex capture, append, and apply.
799 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
800 dynamically loaded, so this may make the library compatible with Windows
801 XP (however, there may still be other problems).
804 Added experimental support for native Windows builds. Binaries can be
805 downloaded from the SourceForge page.
807 --source-list option added to `imagex capture' and `imagex append'.
809 Better support for different character encodings.
812 Storing UNIX file owners, groups, and modes in WIM images is now
813 possible using `imagex capture' with the --unix-data flag.
815 Minor bug fixes and documentation fixes.
818 NTFS capture: Fixed capturing duplicate reparse points.
820 NTFS capture: Capture first unnamed stream if there are more than one
821 (print warning instead of error).
823 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
826 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
829 Update to work with ntfs-3g version 2013.1.13.
832 Fixed truncating file to shorter but non-zero length on read-write
835 Various code cleanups and minor documentation fixes.
838 LZX and XPRESS decompression have received some additional optimizations
839 and should now be even faster. (Although, they were already pretty
840 fast--- much faster than typical I/O speeds.)
842 Fixed a bug introduced in v1.2.1 that would cause a directory tree
843 containing hard links to be captured incorrectly in some cases.
846 By default, unmounting a read-write mounted WIM with 'imagex unmount
847 --commit' will now change the WIM in-place without needing to write the
848 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
851 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
852 for a response from the daemon servicing the mounted WIM. Instead,
853 every second 'imagex unmount' will check if the daemon is still alive,
854 and keep waiting if so, otherwise terminate with an error.
856 'imagex unmount --commit' on a read-write mounted WIM will now print
857 progress information regarding the writing of new or modified streams
858 the WIM, just like when capturing or appending a WIM.
860 A small change has been made to XPRESS compression and it should improve
861 the compression ratio slightly.
863 A change was made that may improve performance slightly when applying a
864 WIM image to a NTFS volume.
866 Microsoft has managed to introduce even more bugs into their software,
867 and now the WIMs for Windows 8 have incorrect (too low) reference counts
868 for some streams. This is unsafe because such streams can be removed
869 when they are in actuality still referenced in the WIM (perhaps by a
870 different image). wimlib will now work around this problem by fixing
871 the stream reference counts. This is only done when wimlib_delete_image() is
872 called ('imagex delete') or when wimlib_mount_image() is called with
873 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
874 requires reading the metadata for all images in the WIM, so this will
875 make these operations noticably slower on WIMs with multiple images.
877 Various other bugfixes.
880 Appending images to a WIM is now be done by default without re-building
881 the whole WIM. Use the --rebuild flag to get the old behavior (which
882 was to re-build the entire WIM when a new image is appended).
884 A new command `imagex optimize' is now available to manually re-build a
885 WIM that has wasted space due to repeated appends.
887 Progress information has been improved, and now arbitrary callback
888 functions can be used to show the progress of a WIM operation.
890 A possible bug with changing the bootable image of a WIM was fixed.
892 Some advisory locking is now done to prevent two processes from
893 modifying a WIM at the same time (but only in some cases). For example,
894 you cannot mount two images from a WIM read-write at the same time.
896 Some functions have been reorganized:
897 * wimlib_mount() renamed to wimlib_mount_image().
898 * wimlib_unmount() renamed to wimlib_unmount_image().
899 * wimlib_overwrite_xml_and_header() removed as
900 wimlib_overwrite() suffices now.
901 * wimlib_apply_image_to_ntfs_volume() removed as
902 wimlib_extract_image() suffices now.
903 * wimlib_add_image_from_ntfs_volume() removed as
904 * wimlib_add_image() suffices now.
906 Previously, the soname of libwim.so has been 0.0.0, despite many
907 interface changes. The soname is now updated to 1.0.0 and will now be
908 updated each release.
911 Resources will now be compressed using multiple threads by default.
912 (This applies to `imagex capture', `imagex append', and `imagex
915 Some performance improvements in mounted WIMs.
917 More progress information is shown when capturing a WIM.
920 Lots of minor fixes, code cleanups, and some documentation updates.
921 Nothing in particular is really noteworthy.
924 LZX and XPRESS compression improvements.
926 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
927 Link Bytes of the WIM.
930 Fixed bug when capturing NTFS file with multiple named data streams.
932 Internally, we are now using inode structures, even though these don't
933 appear literally in the WIM file. This simplifies some of the code
934 (mainly for WIM mounting) and likely fixed a few problems, although it
938 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
942 Enough changes to call it version 1.0.0!
944 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
945 to a NTFS volume, is now supported.
947 Hard links and symbolic links have much improved support. They are
948 supported for WIM capture, WIM application, and mounted WIMs (you can
949 even make them on read-write mounted WIMs).
951 Alternate data streams are now supported on mounted WIMs through an
952 xattr or a Windows-style stream interface. Also they are supported when
953 capturing a WIM from NTFS or applying a WIM to NTFS.
955 Split WIMs are better supported. You may now apply an image directly
956 from a split WIM, mount an image from a split WIM read-only, or export
957 an image from a split WIM.
959 Using a capture configuration file is now supported (but not fully yet).
961 SHA1 message digests are checked in more places, so we can make sure
962 applied and captured data is correct.
964 Man pages have been updated and consolidated.
967 Fixed segfault when unmounting read-only WIM.
970 Support for joining and splitting WIMs.
971 Also, security data is now preserved by default.
974 Can now build with older gcc and system headers, like on CentOS 5.
977 Fixed bug that made it impossible to overwrite files in read-write
981 Write byte-order mark before WIM XML data. (imagex.exe requires this to
