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 On Windows, to improve capture performance, wimlib now sometimes opens
14 files by inode number rather than by path. This is enabled for
15 wimcapture and wimappend, but for now other applications have to opt-in.
17 The progress messages printed by wimlib-imagex while writing WIM files
18 have been slightly tweaked.
20 Progress information for directory tree scans now counts all hard links.
21 Also, on Windows "\\?\" is no longer stripped from the current path.
23 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
24 'wiminfo'. This option lets you assign values to elements in a WIM
25 file's XML document by name.
27 The wimlib_get_image_property() and wimlib_set_image_property() API
28 functions now support numerically indexed elements.
30 Fixed a bug where, on Windows, wimlib would change the security
31 descriptor of the target directory of an extraction even when the
32 '--no-acls' option was specified.
35 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
36 some Microsoft software would not correctly recognize data in the
39 Made some small improvements to the compression algorithms:
40 LZX compression ratio was slightly improved.
41 XPRESS compression ratio and speed was slightly improved.
42 LZMS compression speed was slightly improved.
44 Improved handling of WIM XML data. wimlib no longer drops unrecognized
45 elements when exporting images. In addition, two API functions were
46 added for better access to elements in the XML document:
47 wimlib_get_image_property() and wimlib_set_image_property().
49 Added support for (unsafe) in-place compaction of WIM files.
51 Improved performance of image export by reusing metadata resources
52 instead of always rebuilding and recompressing them.
54 Improved performance of wimlib_update_image() by delaying the update to
55 the WIM's XML document until a write is requested.
57 On Windows, the target of an extraction may now be a reparse point
58 (which will be dereferenced).
60 On Windows, wimlib now correctly restores non-Microsoft reparse points.
61 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
63 On Windows, wimlib now has improved performance when archiving files
64 from a filesystem backed by a WIM (a "WIMBoot" setup).
66 Several improvements to System Compression (compact mode) support:
68 wof.sys (or wofadk.sys) is now automatically attached to the
69 target volume if needed.
71 Compact-mode extractions now work correctly with wofadk.sys on
72 older versions of Windows.
74 For compatibility with the Windows bootloader, the requested
75 compression format now is overridden on certain files.
80 This release primarily contains various minor bug fixes and
81 improvements, including:
83 Improved handling of deep directory structures.
85 Fixed a bug where on 32-bit systems, the library could enter an
86 infinite loop if a WIM file was malformed in a specific way.
88 Added a workaround for a case where libntfs-3g may report
89 duplicate streams in an NTFS file.
91 Windows symbolic links and junctions in mounted WIM images are
92 now automatically rewritten to be valid in the mounted location.
94 Reparse point fixes: correctly handle the "ReparseReserved"
95 field, and correctly handle "empty" (data-less) reparse points.
97 On Windows, wimlib now acquires SeManageVolumePrivilege, which
98 is needed to create externally backed files using the
101 Improved validation of filenames.
103 Improved LZMS decompression speed.
105 The configure script now honors alternate pkg-config settings.
107 Links have been updated to point to the new website.
109 In addition, experimental support has been added for compressing
110 extracted files using System Compression on Windows 10. This
111 functionality is available through the new '--compact' option to
112 'wimapply' and 'wimextract' as well as new library flags.
115 Fixed a bug in the LZX decompressor: malicious input data could cause
116 out of bounds writes to memory (since wimlib v1.2.2).
118 The output of the 'wiminfo' command now consolidates various boolean
119 flags (such as "Relative path junction") into a single line.
121 A file can now have both an unnamed data stream ("file contents") and a
122 reparse point stream. Such files can exist as a result of the use of
123 certain Windows features, such as offline storage, including "OneDrive".
124 wimlib will now store and restore both streams on Windows as well as in
125 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
127 On Windows, named data streams of encrypted files are no longer stored
128 twice in WIM archives.
130 On Windows, named data streams are now correctly extracted to existing
131 "readonly" directories. Before, an error would be reported.
133 On Windows, it is now possible to do a "WIMBoot mode" extraction with
134 non-standalone WIMs such as delta WIMs.
136 On Windows, when doing an extraction in "WIMBoot mode", files larger
137 than 4 gigabytes are now never extracted as externally backed. This
138 works around a bug in Microsoft's "WOF" driver.
140 The '--enable-verify-compression' configure option has been removed. If
141 you want to verify a WIM file, use the 'wimverify' program.
143 The way the "file count", "directory count", "total bytes", and "hard
144 link bytes" image statistics (stored in the WIM XML data) is calculated
145 has been slightly changed.
147 In mounted WIM images, the disk usage provided for each file (st_blocks)
148 is now the compressed size rather than the uncompressed size.
150 The performance of the NTFS-3g and Windows capture modes has been
153 On UNIX-like systems, symbolic links whose targets contain the backslash
154 character are now handled correctly (losslessly).
157 Improved the LZX compressor. It is now 15-20% faster than before and
158 provides a slightly better compression ratio.
160 Improved the LZMS compressor. It now provides a compression ratio
161 slightly better than WIMGAPI while still being faster and using slightly
164 The compression chunk size in solid resources, e.g. when capturing or
165 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
166 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
167 better compression ratio and is the same value that WIMGAPI uses. The
168 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
169 lower than WIMGAPI's memory usage, but if it is too much, it is still
170 possible to choose a lower value, e.g. with the '--solid-chunk-size'
171 option to wimlib-imagex.
173 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
174 accept the 'K', 'M', and 'G' suffixes.
176 Files are now sorted by name extension when creating a solid WIM file.
178 Fixed various issues related to capture/apply of EFS-encrypted files on
181 The file list printed by 'wimdir' is now sorted by the platform-specific
182 case sensitivity setting, rather than always case sensitively. This
183 also affects the library function wimlib_iterate_dir_tree().
185 On Windows, some error and warning messages have been improved.
188 The Windows binary distribution no longer contains third party DLLs.
189 These dependencies are instead compiled directly into the libwim DLL.
191 Added more fixes for wimlib on non-x86 architectures such as ARM.
193 Extracting files to a Windows PE in-memory filesystem no longer fails if
194 the target files do not yet exist.
196 Improved the performance of XPRESS compression and LZMS decompression.
198 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
199 It will automatically be faster on newer Intel and AMD processors.
201 Removed the --with-imagex-progname and --enable-more-assertions
205 Fix for very slow export from solid WIM / ESD files.
207 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
209 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
210 may use this to treat some types of errors as non-fatal.
212 The library now permits making in-memory changes to a WIMStruct backed
213 by a read-only WIM file.
215 Fixes for "WIMBoot" extraction mode (Windows only):
217 When not using the WOF driver, extraction no longer fails if the
218 disk containing the WIM file has too many partitions.
220 When matching patterns in [PrepopulateList], all hard links of
221 each file are now considered.
223 The system registry files are now automatically treated as being
224 in [PrepopulateList].
226 Added a hack to try to work around an intermittent bug in
227 Microsoft's WOF (Windows Overlay Filesystem) driver.
230 Made more improvements to the XPRESS, LZX, and LZMS compressors.
232 A number of improvements to the Windows port:
234 Fixes for setting short filenames.
236 Faster "WIMBoot" extraction.
238 Updated and slimmed down the dependent DLLs.
240 ACL inheritence bits are now restored.
242 Mandatory integrity labels are now backed up and restored.
244 Added a workaround for an issue where in rare cases, wimlib could create
245 a compressed data stream that could not be read correctly by Windows
246 after an extraction in "WIMBoot" mode.
249 Added file count progress data for
250 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
251 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
253 Added support for testing file exclusions via the user-provided
256 Some documentation improvements.
258 Made some clarifications to the license text in the COPYING file.
261 Made more improvements to the XPRESS, LZX, and LZMS compressors.
263 The default compression mode for wimcapture is now LZX compression in
264 its default mode, which is the same as '--compress=maximum'.
266 You can now specify an optional integer compression level to the
267 '--compress' option; e.g. '--compress=lzx:75'.
269 Made a minor change to the LZMS compressor and decompressor to fix an
270 incompatibility with the Microsoft implementation. In the unlikely
271 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
272 earlier and a checksum error is reported when extracting files from it
273 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
276 Added 'verify' subcommand to wimlib-imagex.
278 Notable library changes:
280 Custom compressor parameters have been removed from the library
281 in favor of the simpler level-based API.
283 Decompressor parameters have been removed entirely.
285 Library users can now specify a custom file for warning and
286 error messages to be sent to, rather than the default of
289 New progress messages:
290 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
291 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
293 New function: wimlib_verify_wim().
296 Improved compression, decompression, and extraction performance.
298 Improved compatibility with version 3584 WIM / ESD files:
299 - Add support for reading and writing multiple solid blocks per
300 archive, which WIMGAPI/DISM can create when appending an image.
301 - Correctly create solid blocks larger than 4 GiB.
303 'add' commands passed to wimupdate will now replace existing
304 nondirectory files by default. Use the --no-replace option to get the
307 The license for the library now contains an exception that allows using
308 it under the LGPL. See the COPYING file for details.
310 In reparse-point fixup mode (the default for capture), symbolic links
311 and junctions that point outside the tree being captured are no longer
312 excluded from capture.
314 Added support for "WIMBoot" capture and extraction. See the
315 documentation for the new '--wimboot' option to wimcapture and wimapply
316 for more information.
318 On UNIX-like systems, you can now backup and restore device nodes, named
319 pipes, and sockets. In addition, 32-bit user and group IDs are now
322 The way that UNIX data is stored in WIM files has been changed. If you
323 captured any WIMs with the --unix-data option, to upgrade them you'll
324 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
325 re-capture them with --unix-data using this version.
327 wimlib now understands tagged metadata items, such as object IDs, that
328 can be stored in WIM directory entries.
330 Removed the --hardlink and --symlink options to wimapply, since I don't
331 think they are too useful and they got in the way of improving the code.
333 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
335 The 'mkwinpeimg' script now supports writing the ISO image to standard
338 The <ARCH> element in WIM XML data is now exported correctly.
340 On Windows, sparse file attributes are no longer set on extracted files.
341 Oddly enough, this actually saves disk space in some cases.
343 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
344 supported. Mounting WIM images now always requires extended attribute
345 support. Use --without-fuse to disable support for mounting WIM images;
346 this will also disable the need for extended attribute support.
348 Configuring with --enable-ssse3-sha1 now works correctly.
350 The shared library version has been bumped up. The main
351 incompatibilities are:
353 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
354 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
357 - User-provided progress functions are now registered using a
358 separate function, wimlib_register_progress_function(). The
359 'progress_func' argument to many functions no longer exists.
361 - The return value from user-provided progress functions is now
364 - A context argument has been added to the prototype of
365 user-provided progress functions.
367 - 'struct wimlib_capture_config' has been removed. The library
368 now takes the path to the configuration file directly. This
369 affects wimlib_add_image(), wimlib_add_image_multisource(),
370 and wimlib_update_image(). However, a NULL value passed in
371 the argument retains the same meaning.
373 - Removed deprecated functions: some (de)compression functions,
374 wimlib_extract_files(), and wimlib_print_metadata().
376 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
377 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
378 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
380 - Removed some progress messages:
381 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
382 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
383 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
386 - Removed some error codes. Numbering stays the same.
388 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
389 WIMLIB_UNMOUNT_FLAG_FORCE.
391 - WIM paths passed to progress functions now have a leading
395 Case-insensitive comparisons of strings (e.g. filenames) containing
396 UTF-16 codepoints above 32767 are now done correctly.
398 Fixed build failure on Mac OS X.
400 wimunmount now provides the '--new-image' option to cause changes to a
401 read-write mounted image to be committed as a new image rather than as
402 an update of the mounted image. (The corresponding new library flag is
403 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
405 The LZMS ("recovery") compression chunk size, or "dictionary size", may
406 now be up to 1 GiB (1,073,741,824 bytes).
408 The performance of LZX ("maximum") and LZMS ("recovery") compression
409 with large chunk sizes has been slightly improved.
412 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
413 decompressed correctly.
415 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
416 occurred in an unlikely case, and due to validity checks it did not
417 affect successfully created archives.
419 Fixed a minor compatibility issue with the LZMS compressor and
420 decompressor. This is *not* the default compression type and was only
421 introduced in v1.6.0. In the unlikely event that you created an
422 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
423 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
426 Memory usage for LZMS and LZX compression has been decreased.
428 wimextract now allows wildcard characters in paths specified on the
429 command line. Also, the '--strict-wildcards' option has been removed
430 and replaced with the inverse option '--nullglob'. See the
431 documentation for wimextract for more details and changes.
433 The wimlib_extract_files() function is now considered deprecated in
434 favor of wimlib_extract_paths().
436 Fixed more permissions problems when extracting files on Windows.
438 A new '--no-attributes' option has been added to wimapply and
439 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
441 The default chunk size is now set correctly when changing the
442 compression type of a WIM, for example with 'wimoptimize'.
444 The '--metadata' option to wiminfo has been replaced with the
445 '--detailed' option to wimdir.
447 In relevant wimlib-imagex commands, '--solid' may now be used as an
448 alias for '--pack-streams'.
451 Support for extracting and updating the new version 3584 WIMs has been
452 added. These WIMs typically pack many streams ("files") together into a
453 single compressed resource, thereby saving space. This degrades the
454 performance of random access (such as that which occurs on a mounted
455 image), but optimizations have been implemented for extraction. These
456 new WIM files also typically use a new compression format (LZMS), which
457 is similar to LZMA and can offer a better compression ratio than LZX.
458 These new WIM files can be created using `wimcapture' with
459 the '--compress=lzms --pack-streams' options. Note: this new WIM format
460 is used by the Windows 8 web downloader, but important segments of the
461 raw '.esd' files are encrypted, so wimlib will not be able to extract
462 such files until they are first decrypted.
464 wimlib now supports extracting files and directories from a WIM image
465 based on a "listfile" that itself contains the list of paths to extract.
466 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
467 and for the library itself, the new APIs are wimlib_extract_pathlist()
468 and wimlib_extract_paths(). Path globs containing wildcard characters
471 For searching WIM files, wimlib now has configurable case sensitivity.
472 The default on Windows is still case-insensitive and the default on
473 UNIX-like systems is still case-sensitive, but this can be overridden
474 on either platform through flags to wimlib_global_init(). For
475 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
476 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
479 Support for compression chunk sizes greater than the default of 32768
480 bytes has been added. A larger chunk size typically results in a better
481 compression ratio. However, the MS implementation is seemingly not
482 compatible with all chunk sizes, especially for LZX compression, so the
483 defaults remain unchanged, with the exception of the new LZMS-compressed
484 WIMs, which use a larger chunk size by default.
486 The compression/decompression API exported by wimlib has been changed.
487 Now one set of functions handles all supported compression formats.
489 `wimcapture' and `wimappend' will now display the progress of scanning
490 the directory tree to capture, in addition to the progress of writing
491 data to the WIM. The '--verbose' option no longer does anything. The
492 library API change for this is the addition of several members to
493 `struct wimlib_progress_info_scan' available to progress callbacks.
495 `mkwinpeimg' now correctly handles the '--start-script' option when the
496 start script is not in the working directory.
498 Sequential extraction, previously requested by using
499 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
500 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
501 behavior (extract in file order).
504 The new LZX compressor added in v1.5.2 has been improved and is now
505 enabled by default, except when `wimcapture' or `wimappend' is run
506 *without* the '--compress' option, in which case the faster LZX
507 compressor is used (the same as before). This behavior is reasonably
508 consistent with ImageX which actually uses "fast" (XPRESS) compression
509 by default. In those cases, use '--compress=maximum' to explicitly
510 capture a WIM image using the new (slower but better) LZX compressor.
512 The '--compress-slow' option still exists to `wimlib-imagex optimize',
513 but its new behavior is to tweak the new LZX compressor even more to
514 produce an even better compression ratio at the cost of more time spent
517 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
518 which recompresses the WIM file using the specified compression TYPE.
519 The new library API function used for this is
520 wimlib_set_output_compression_type().
522 Added the wimlib_get_xml_data() function to allow library clients to
523 easily retrieve the raw XML data from a WIM file if needed.
525 Fixed a bug that could cause an error code to be incorrectly returned
526 when writing XML data containing a <WINDOWS> element.
528 Mounted WIM images will now correctly show the default file stream even
529 if appears in the alternate data stream entries of the corresponding WIM
533 Added a new experimental LZX compressor which can be enabled by passing
534 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
535 optimize'. (The latter is only applicable if the WIM is already
536 LZX-compressed and the '--recompress' option is also given.) The
537 experimental compressor is much slower but compresses the data slightly
538 more --- currently usually to within a fraction of a percent of the
539 results from WIMGAPI/ImageX.
541 A workaround has been added for compatibility with versions of WinPE
542 that interpret alternate data stream entries in the boot WIM
545 An alignment bug that caused a crash in the LZX decompressor on some
548 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
549 the WIM header when restoring the previous state of a WIM it failed to
552 Added a workaround to avoid an access denied error on Windows when
553 replacing a WIM file that another process has opened.
556 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
557 needed to be handled.
559 A bug in the interpretation of negative IMAGE indices in the
560 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
561 `wimlib-imagex append' has been fixed.
563 A workaround has been added to successfully apply security descriptors
564 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
565 2013.1.13 or earlier.
567 `wimlib-imagex capture' can now accept the '--delta-from' option
571 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
572 to standard output and applying images from standard input, but they are
573 not compatible with Microsoft's software and are not created by default.
574 See the documentation for --pipable flag of `wimlib-imagex capture' for
577 To better support incremental backups, added support for declaring an
578 image as a modified form of another image. See the documentation for
579 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
582 Added supported for "delta" WIMs. See the documentation for the
583 '--delta-from' option of `wimlib-imagex capture'.
585 The library support for managing split WIMs has been changed to support
586 other arrangements, such as delta WIMs, and be easier to use. This
587 change is visible in `wimlib-imagex', which also can now accept the
588 '--ref' option multiple times, and also now supports "delta" WIMs as
591 wimlib now preserves WIM integrity tables by default, even if
592 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
593 behavior of `wimlib-imagex' whenever the WIM being operated on contains
594 an integrity table and the '--check' option is not specified.
596 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
597 (when --compress is not specified). This provides the best compression
598 ratio by default, which is usually what is desired, at a cost of some
601 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
602 is the command as in `wimlib-imagex COMMAND'; for example, it can be
603 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
604 appropriate hard links are created in UNIX installations of
605 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
606 batch files that emulate this behavior are generated.
608 Security descriptors are now extracted correctly on Windows.
610 Fixed archiving DOS names in NTFS-3g capture mode.
612 The extraction code has been rewritten and it will now be easier to
613 support new features on all supported backends (currently Win32, UNIX,
614 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
615 now supported on all backends, not just UNIX.
617 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
618 than the WAIK itself.
620 wimlib_global_init() now, by default, attempts to acquire additional
621 privileges on Windows, so library clients need not do this.
623 This update bumps the shared library version number up to 9, since it is
624 not binary compatibible with previous releases.
627 Fixed bug in `wimlib-imagex export' that made it impossible to export an
628 image from a WIM that is readonly at the filesystem level.
630 Return error code rather than segfaulting when trying to list files from
631 a non-first part of a split WIM.
633 Joining a WIM will now preserve the RP_FIX and READONLY flags.
636 On Windows, paths given to wimlib-imagex are now treated case
639 Improved behavior regarding invalid filenames; in particular, on
640 Windows, wimlib-imagex will, when extracting, now omit (with an option
641 to override this default) filenames differing only in case, or filenames
642 containing characters not valid on Windows.
644 On Windows, wimlib now supports capturing and extracting long paths
645 (longer than the so-called MAX_PATH).
647 On Windows, `wimlib-imagex update' now acquires proper privileges when
648 running as an Administrator.
650 `wimlib-imagex update' will now complain if no image is specified when
651 trying to update a multi-image WIM.
653 `wimlib-imagex update' now supports specifying a single update command
654 directly on the command line using the --command option.
656 wimlib-imagex will now choose different units for progress messages,
657 depending on the amount of data that needs to be processed.
659 `wimlib-imagex append' will now generate a unique WIM image name if no
660 name is specified and the defaulted name already exists in the WIM.
662 wimlib now allows you to create unnamed WIM images, which can then only
663 be referred to by index.
665 wimlib now allows you to explicitly declare you want write access to a
666 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
669 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
672 Progress callbacks have been added to wimlib's wimlib_update_image()
675 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
676 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
679 NTFS-3g capture now only warns about two conditions previously treated
682 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
685 wimlib now correctly detects and returns an error when reading a WIM
686 image with a cyclic directory structure. (Fun fact: such a WIM will
687 crash Microsoft's software.)
690 Added new "extract" and "update" subcommands to wimlib-imagex, along
691 with associated APIs in the library. These commands are intended mainly
692 for Windows use but can be used on UNIX as well.
694 Many documentation improvements.
696 Fixed a bug in the Windows build where relative symbolic links were not
697 captured in reparse-point fixup mode.
699 Fixed a bug in the Windows build where file handles were left open to
700 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
702 Fixed a bug in the Windows build of wimlib-imagex where globbing
703 split-WIM parts could cause the program to crash.
705 Fixed a bug where the creation time of WIM images would be shown instead
706 of the last modification time.
708 With the Windows build it is now possible to restore a WIM containing
709 symbolic links as a non-Administrator; however you will receive warnings
710 about not being able to extract the symbolic links.
713 Capturing a WIM image should now be significantly faster in most cases
714 due to improved use of the operating system's cache and avoiding reading
715 files twice whenever possible.
717 The Windows build should now work on Windows XP.
719 The Windows build now supports capturing and restoring hidden,
720 compressed, sparse, and encrypted files.
722 The Windows build now supports capturing and applying WIM images from
723 filesystems other than NTFS (with some reduced functionality).
725 The Windows build now extracts short names correctly.
727 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
728 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
729 capture' and `wimlib-imagex apply'.
731 The performance of splitting and joining WIMs should be slightly
734 The LZX and XPRESS compression and decompression functions are now
735 exported from the library.
738 Improvements and bugfixes for the Windows build.
740 Added --strict-acls options.
742 Fixed the way that wimlib determines the order of images in the WIM.
745 Since wimlib can now be used on Windows, wimlib's implementation of
746 ImageX has been renamed to wimlib-imagex to avoid confusion with
747 Microsoft's implementation of ImageX, which would have the same file
748 name ("imagex.exe"). If you really don't like this you can pass the
749 --with-imagex-progname option to `configure' to choose a different name,
750 or even simply rename the binary yourself (but the former way will
751 configure the man pages to use the chosen name).
753 Various bugs fixed in the Windows build. Mainly to do with capturing
754 and restoring alternate data streams correctly in weird cases, and
755 requesting the correct privileges when opening files. Also added the
756 --noacls options to wimlib-imagex capture, append, and apply.
758 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
759 dynamically loaded, so this may make the library compatible with Windows
760 XP (however, there may still be other problems).
763 Added experimental support for native Windows builds. Binaries can be
764 downloaded from the SourceForge page.
766 --source-list option added to `imagex capture' and `imagex append'.
768 Better support for different character encodings.
771 Storing UNIX file owners, groups, and modes in WIM images is now
772 possible using `imagex capture' with the --unix-data flag.
774 Minor bug fixes and documentation fixes.
777 NTFS capture: Fixed capturing duplicate reparse points.
779 NTFS capture: Capture first unnamed stream if there are more than one
780 (print warning instead of error).
782 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
785 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
788 Update to work with ntfs-3g version 2013.1.13.
791 Fixed truncating file to shorter but non-zero length on read-write
794 Various code cleanups and minor documentation fixes.
797 LZX and XPRESS decompression have received some additional optimizations
798 and should now be even faster. (Although, they were already pretty
799 fast--- much faster than typical I/O speeds.)
801 Fixed a bug introduced in v1.2.1 that would cause a directory tree
802 containing hard links to be captured incorrectly in some cases.
805 By default, unmounting a read-write mounted WIM with 'imagex unmount
806 --commit' will now change the WIM in-place without needing to write the
807 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
810 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
811 for a response from the daemon servicing the mounted WIM. Instead,
812 every second 'imagex unmount' will check if the daemon is still alive,
813 and keep waiting if so, otherwise terminate with an error.
815 'imagex unmount --commit' on a read-write mounted WIM will now print
816 progress information regarding the writing of new or modified streams
817 the WIM, just like when capturing or appending a WIM.
819 A small change has been made to XPRESS compression and it should improve
820 the compression ratio slightly.
822 A change was made that may improve performance slightly when applying a
823 WIM image to a NTFS volume.
825 Microsoft has managed to introduce even more bugs into their software,
826 and now the WIMs for Windows 8 have incorrect (too low) reference counts
827 for some streams. This is unsafe because such streams can be removed
828 when they are in actuality still referenced in the WIM (perhaps by a
829 different image). wimlib will now work around this problem by fixing
830 the stream reference counts. This is only done when wimlib_delete_image() is
831 called ('imagex delete') or when wimlib_mount_image() is called with
832 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
833 requires reading the metadata for all images in the WIM, so this will
834 make these operations noticably slower on WIMs with multiple images.
836 Various other bugfixes.
839 Appending images to a WIM is now be done by default without re-building
840 the whole WIM. Use the --rebuild flag to get the old behavior (which
841 was to re-build the entire WIM when a new image is appended).
843 A new command `imagex optimize' is now available to manually re-build a
844 WIM that has wasted space due to repeated appends.
846 Progress information has been improved, and now arbitrary callback
847 functions can be used to show the progress of a WIM operation.
849 A possible bug with changing the bootable image of a WIM was fixed.
851 Some advisory locking is now done to prevent two processes from
852 modifying a WIM at the same time (but only in some cases). For example,
853 you cannot mount two images from a WIM read-write at the same time.
855 Some functions have been reorganized:
856 * wimlib_mount() renamed to wimlib_mount_image().
857 * wimlib_unmount() renamed to wimlib_unmount_image().
858 * wimlib_overwrite_xml_and_header() removed as
859 wimlib_overwrite() suffices now.
860 * wimlib_apply_image_to_ntfs_volume() removed as
861 wimlib_extract_image() suffices now.
862 * wimlib_add_image_from_ntfs_volume() removed as
863 * wimlib_add_image() suffices now.
865 Previously, the soname of libwim.so has been 0.0.0, despite many
866 interface changes. The soname is now updated to 1.0.0 and will now be
867 updated each release.
870 Resources will now be compressed using multiple threads by default.
871 (This applies to `imagex capture', `imagex append', and `imagex
874 Some performance improvements in mounted WIMs.
876 More progress information is shown when capturing a WIM.
879 Lots of minor fixes, code cleanups, and some documentation updates.
880 Nothing in particular is really noteworthy.
883 LZX and XPRESS compression improvements.
885 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
886 Link Bytes of the WIM.
889 Fixed bug when capturing NTFS file with multiple named data streams.
891 Internally, we are now using inode structures, even though these don't
892 appear literally in the WIM file. This simplifies some of the code
893 (mainly for WIM mounting) and likely fixed a few problems, although it
897 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
901 Enough changes to call it version 1.0.0!
903 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
904 to a NTFS volume, is now supported.
906 Hard links and symbolic links have much improved support. They are
907 supported for WIM capture, WIM application, and mounted WIMs (you can
908 even make them on read-write mounted WIMs).
910 Alternate data streams are now supported on mounted WIMs through an
911 xattr or a Windows-style stream interface. Also they are supported when
912 capturing a WIM from NTFS or applying a WIM to NTFS.
914 Split WIMs are better supported. You may now apply an image directly
915 from a split WIM, mount an image from a split WIM read-only, or export
916 an image from a split WIM.
918 Using a capture configuration file is now supported (but not fully yet).
920 SHA1 message digests are checked in more places, so we can make sure
921 applied and captured data is correct.
923 Man pages have been updated and consolidated.
926 Fixed segfault when unmounting read-only WIM.
929 Support for joining and splitting WIMs.
930 Also, security data is now preserved by default.
933 Can now build with older gcc and system headers, like on CentOS 5.
936 Fixed bug that made it impossible to overwrite files in read-write
940 Write byte-order mark before WIM XML data. (imagex.exe requires this to
