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 Improved performance of directory tree scans on Windows.
12 On Windows, to improve capture performance, wimlib now sometimes opens
13 files by inode number rather than by path. This is enabled for
14 wimcapture and wimappend, but for now other applications have to opt-in.
16 The progress messages printed by wimlib-imagex while writing WIM files
17 have been slightly tweaked.
19 Progress information for directory tree scans now counts all hard links.
20 Also, on Windows "\\?\" is no longer stripped from the current path.
22 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
23 'wiminfo'. This option lets you assign values to elements in a WIM
24 file's XML document by name.
26 The wimlib_get_image_property() and wimlib_set_image_property() API
27 functions now support numerically indexed elements.
29 Fixed a bug where, on Windows, wimlib would change the security
30 descriptor of the target directory of an extraction even when the
31 '--no-acls' option was specified.
34 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
35 some Microsoft software would not correctly recognize data in the
38 Made some small improvements to the compression algorithms:
39 LZX compression ratio was slightly improved.
40 XPRESS compression ratio and speed was slightly improved.
41 LZMS compression speed was slightly improved.
43 Improved handling of WIM XML data. wimlib no longer drops unrecognized
44 elements when exporting images. In addition, two API functions were
45 added for better access to elements in the XML document:
46 wimlib_get_image_property() and wimlib_set_image_property().
48 Added support for (unsafe) in-place compaction of WIM files.
50 Improved performance of image export by reusing metadata resources
51 instead of always rebuilding and recompressing them.
53 Improved performance of wimlib_update_image() by delaying the update to
54 the WIM's XML document until a write is requested.
56 On Windows, the target of an extraction may now be a reparse point
57 (which will be dereferenced).
59 On Windows, wimlib now correctly restores non-Microsoft reparse points.
60 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
62 On Windows, wimlib now has improved performance when archiving files
63 from a filesystem backed by a WIM (a "WIMBoot" setup).
65 Several improvements to System Compression (compact mode) support:
67 wof.sys (or wofadk.sys) is now automatically attached to the
68 target volume if needed.
70 Compact-mode extractions now work correctly with wofadk.sys on
71 older versions of Windows.
73 For compatibility with the Windows bootloader, the requested
74 compression format now is overridden on certain files.
79 This release primarily contains various minor bug fixes and
80 improvements, including:
82 Improved handling of deep directory structures.
84 Fixed a bug where on 32-bit systems, the library could enter an
85 infinite loop if a WIM file was malformed in a specific way.
87 Added a workaround for a case where libntfs-3g may report
88 duplicate streams in an NTFS file.
90 Windows symbolic links and junctions in mounted WIM images are
91 now automatically rewritten to be valid in the mounted location.
93 Reparse point fixes: correctly handle the "ReparseReserved"
94 field, and correctly handle "empty" (data-less) reparse points.
96 On Windows, wimlib now acquires SeManageVolumePrivilege, which
97 is needed to create externally backed files using the
100 Improved validation of filenames.
102 Improved LZMS decompression speed.
104 The configure script now honors alternate pkg-config settings.
106 Links have been updated to point to the new website.
108 In addition, experimental support has been added for compressing
109 extracted files using System Compression on Windows 10. This
110 functionality is available through the new '--compact' option to
111 'wimapply' and 'wimextract' as well as new library flags.
114 Fixed a bug in the LZX decompressor: malicious input data could cause
115 out of bounds writes to memory (since wimlib v1.2.2).
117 The output of the 'wiminfo' command now consolidates various boolean
118 flags (such as "Relative path junction") into a single line.
120 A file can now have both an unnamed data stream ("file contents") and a
121 reparse point stream. Such files can exist as a result of the use of
122 certain Windows features, such as offline storage, including "OneDrive".
123 wimlib will now store and restore both streams on Windows as well as in
124 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
126 On Windows, named data streams of encrypted files are no longer stored
127 twice in WIM archives.
129 On Windows, named data streams are now correctly extracted to existing
130 "readonly" directories. Before, an error would be reported.
132 On Windows, it is now possible to do a "WIMBoot mode" extraction with
133 non-standalone WIMs such as delta WIMs.
135 On Windows, when doing an extraction in "WIMBoot mode", files larger
136 than 4 gigabytes are now never extracted as externally backed. This
137 works around a bug in Microsoft's "WOF" driver.
139 The '--enable-verify-compression' configure option has been removed. If
140 you want to verify a WIM file, use the 'wimverify' program.
142 The way the "file count", "directory count", "total bytes", and "hard
143 link bytes" image statistics (stored in the WIM XML data) is calculated
144 has been slightly changed.
146 In mounted WIM images, the disk usage provided for each file (st_blocks)
147 is now the compressed size rather than the uncompressed size.
149 The performance of the NTFS-3g and Windows capture modes has been
152 On UNIX-like systems, symbolic links whose targets contain the backslash
153 character are now handled correctly (losslessly).
156 Improved the LZX compressor. It is now 15-20% faster than before and
157 provides a slightly better compression ratio.
159 Improved the LZMS compressor. It now provides a compression ratio
160 slightly better than WIMGAPI while still being faster and using slightly
163 The compression chunk size in solid resources, e.g. when capturing or
164 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
165 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
166 better compression ratio and is the same value that WIMGAPI uses. The
167 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
168 lower than WIMGAPI's memory usage, but if it is too much, it is still
169 possible to choose a lower value, e.g. with the '--solid-chunk-size'
170 option to wimlib-imagex.
172 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
173 accept the 'K', 'M', and 'G' suffixes.
175 Files are now sorted by name extension when creating a solid WIM file.
177 Fixed various issues related to capture/apply of EFS-encrypted files on
180 The file list printed by 'wimdir' is now sorted by the platform-specific
181 case sensitivity setting, rather than always case sensitively. This
182 also affects the library function wimlib_iterate_dir_tree().
184 On Windows, some error and warning messages have been improved.
187 The Windows binary distribution no longer contains third party DLLs.
188 These dependencies are instead compiled directly into the libwim DLL.
190 Added more fixes for wimlib on non-x86 architectures such as ARM.
192 Extracting files to a Windows PE in-memory filesystem no longer fails if
193 the target files do not yet exist.
195 Improved the performance of XPRESS compression and LZMS decompression.
197 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
198 It will automatically be faster on newer Intel and AMD processors.
200 Removed the --with-imagex-progname and --enable-more-assertions
204 Fix for very slow export from solid WIM / ESD files.
206 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
208 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
209 may use this to treat some types of errors as non-fatal.
211 The library now permits making in-memory changes to a WIMStruct backed
212 by a read-only WIM file.
214 Fixes for "WIMBoot" extraction mode (Windows only):
216 When not using the WOF driver, extraction no longer fails if the
217 disk containing the WIM file has too many partitions.
219 When matching patterns in [PrepopulateList], all hard links of
220 each file are now considered.
222 The system registry files are now automatically treated as being
223 in [PrepopulateList].
225 Added a hack to try to work around an intermittent bug in
226 Microsoft's WOF (Windows Overlay Filesystem) driver.
229 Made more improvements to the XPRESS, LZX, and LZMS compressors.
231 A number of improvements to the Windows port:
233 Fixes for setting short filenames.
235 Faster "WIMBoot" extraction.
237 Updated and slimmed down the dependent DLLs.
239 ACL inheritence bits are now restored.
241 Mandatory integrity labels are now backed up and restored.
243 Added a workaround for an issue where in rare cases, wimlib could create
244 a compressed data stream that could not be read correctly by Windows
245 after an extraction in "WIMBoot" mode.
248 Added file count progress data for
249 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
250 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
252 Added support for testing file exclusions via the user-provided
255 Some documentation improvements.
257 Made some clarifications to the license text in the COPYING file.
260 Made more improvements to the XPRESS, LZX, and LZMS compressors.
262 The default compression mode for wimcapture is now LZX compression in
263 its default mode, which is the same as '--compress=maximum'.
265 You can now specify an optional integer compression level to the
266 '--compress' option; e.g. '--compress=lzx:75'.
268 Made a minor change to the LZMS compressor and decompressor to fix an
269 incompatibility with the Microsoft implementation. In the unlikely
270 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
271 earlier and a checksum error is reported when extracting files from it
272 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
275 Added 'verify' subcommand to wimlib-imagex.
277 Notable library changes:
279 Custom compressor parameters have been removed from the library
280 in favor of the simpler level-based API.
282 Decompressor parameters have been removed entirely.
284 Library users can now specify a custom file for warning and
285 error messages to be sent to, rather than the default of
288 New progress messages:
289 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
290 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
292 New function: wimlib_verify_wim().
295 Improved compression, decompression, and extraction performance.
297 Improved compatibility with version 3584 WIM / ESD files:
298 - Add support for reading and writing multiple solid blocks per
299 archive, which WIMGAPI/DISM can create when appending an image.
300 - Correctly create solid blocks larger than 4 GiB.
302 'add' commands passed to wimupdate will now replace existing
303 nondirectory files by default. Use the --no-replace option to get the
306 The license for the library now contains an exception that allows using
307 it under the LGPL. See the COPYING file for details.
309 In reparse-point fixup mode (the default for capture), symbolic links
310 and junctions that point outside the tree being captured are no longer
311 excluded from capture.
313 Added support for "WIMBoot" capture and extraction. See the
314 documentation for the new '--wimboot' option to wimcapture and wimapply
315 for more information.
317 On UNIX-like systems, you can now backup and restore device nodes, named
318 pipes, and sockets. In addition, 32-bit user and group IDs are now
321 The way that UNIX data is stored in WIM files has been changed. If you
322 captured any WIMs with the --unix-data option, to upgrade them you'll
323 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
324 re-capture them with --unix-data using this version.
326 wimlib now understands tagged metadata items, such as object IDs, that
327 can be stored in WIM directory entries.
329 Removed the --hardlink and --symlink options to wimapply, since I don't
330 think they are too useful and they got in the way of improving the code.
332 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
334 The 'mkwinpeimg' script now supports writing the ISO image to standard
337 The <ARCH> element in WIM XML data is now exported correctly.
339 On Windows, sparse file attributes are no longer set on extracted files.
340 Oddly enough, this actually saves disk space in some cases.
342 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
343 supported. Mounting WIM images now always requires extended attribute
344 support. Use --without-fuse to disable support for mounting WIM images;
345 this will also disable the need for extended attribute support.
347 Configuring with --enable-ssse3-sha1 now works correctly.
349 The shared library version has been bumped up. The main
350 incompatibilities are:
352 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
353 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
356 - User-provided progress functions are now registered using a
357 separate function, wimlib_register_progress_function(). The
358 'progress_func' argument to many functions no longer exists.
360 - The return value from user-provided progress functions is now
363 - A context argument has been added to the prototype of
364 user-provided progress functions.
366 - 'struct wimlib_capture_config' has been removed. The library
367 now takes the path to the configuration file directly. This
368 affects wimlib_add_image(), wimlib_add_image_multisource(),
369 and wimlib_update_image(). However, a NULL value passed in
370 the argument retains the same meaning.
372 - Removed deprecated functions: some (de)compression functions,
373 wimlib_extract_files(), and wimlib_print_metadata().
375 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
376 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
377 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
379 - Removed some progress messages:
380 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
381 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
382 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
385 - Removed some error codes. Numbering stays the same.
387 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
388 WIMLIB_UNMOUNT_FLAG_FORCE.
390 - WIM paths passed to progress functions now have a leading
394 Case-insensitive comparisons of strings (e.g. filenames) containing
395 UTF-16 codepoints above 32767 are now done correctly.
397 Fixed build failure on Mac OS X.
399 wimunmount now provides the '--new-image' option to cause changes to a
400 read-write mounted image to be committed as a new image rather than as
401 an update of the mounted image. (The corresponding new library flag is
402 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
404 The LZMS ("recovery") compression chunk size, or "dictionary size", may
405 now be up to 1 GiB (1,073,741,824 bytes).
407 The performance of LZX ("maximum") and LZMS ("recovery") compression
408 with large chunk sizes has been slightly improved.
411 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
412 decompressed correctly.
414 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
415 occurred in an unlikely case, and due to validity checks it did not
416 affect successfully created archives.
418 Fixed a minor compatibility issue with the LZMS compressor and
419 decompressor. This is *not* the default compression type and was only
420 introduced in v1.6.0. In the unlikely event that you created an
421 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
422 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
425 Memory usage for LZMS and LZX compression has been decreased.
427 wimextract now allows wildcard characters in paths specified on the
428 command line. Also, the '--strict-wildcards' option has been removed
429 and replaced with the inverse option '--nullglob'. See the
430 documentation for wimextract for more details and changes.
432 The wimlib_extract_files() function is now considered deprecated in
433 favor of wimlib_extract_paths().
435 Fixed more permissions problems when extracting files on Windows.
437 A new '--no-attributes' option has been added to wimapply and
438 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
440 The default chunk size is now set correctly when changing the
441 compression type of a WIM, for example with 'wimoptimize'.
443 The '--metadata' option to wiminfo has been replaced with the
444 '--detailed' option to wimdir.
446 In relevant wimlib-imagex commands, '--solid' may now be used as an
447 alias for '--pack-streams'.
450 Support for extracting and updating the new version 3584 WIMs has been
451 added. These WIMs typically pack many streams ("files") together into a
452 single compressed resource, thereby saving space. This degrades the
453 performance of random access (such as that which occurs on a mounted
454 image), but optimizations have been implemented for extraction. These
455 new WIM files also typically use a new compression format (LZMS), which
456 is similar to LZMA and can offer a better compression ratio than LZX.
457 These new WIM files can be created using `wimcapture' with
458 the '--compress=lzms --pack-streams' options. Note: this new WIM format
459 is used by the Windows 8 web downloader, but important segments of the
460 raw '.esd' files are encrypted, so wimlib will not be able to extract
461 such files until they are first decrypted.
463 wimlib now supports extracting files and directories from a WIM image
464 based on a "listfile" that itself contains the list of paths to extract.
465 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
466 and for the library itself, the new APIs are wimlib_extract_pathlist()
467 and wimlib_extract_paths(). Path globs containing wildcard characters
470 For searching WIM files, wimlib now has configurable case sensitivity.
471 The default on Windows is still case-insensitive and the default on
472 UNIX-like systems is still case-sensitive, but this can be overridden
473 on either platform through flags to wimlib_global_init(). For
474 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
475 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
478 Support for compression chunk sizes greater than the default of 32768
479 bytes has been added. A larger chunk size typically results in a better
480 compression ratio. However, the MS implementation is seemingly not
481 compatible with all chunk sizes, especially for LZX compression, so the
482 defaults remain unchanged, with the exception of the new LZMS-compressed
483 WIMs, which use a larger chunk size by default.
485 The compression/decompression API exported by wimlib has been changed.
486 Now one set of functions handles all supported compression formats.
488 `wimcapture' and `wimappend' will now display the progress of scanning
489 the directory tree to capture, in addition to the progress of writing
490 data to the WIM. The '--verbose' option no longer does anything. The
491 library API change for this is the addition of several members to
492 `struct wimlib_progress_info_scan' available to progress callbacks.
494 `mkwinpeimg' now correctly handles the '--start-script' option when the
495 start script is not in the working directory.
497 Sequential extraction, previously requested by using
498 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
499 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
500 behavior (extract in file order).
503 The new LZX compressor added in v1.5.2 has been improved and is now
504 enabled by default, except when `wimcapture' or `wimappend' is run
505 *without* the '--compress' option, in which case the faster LZX
506 compressor is used (the same as before). This behavior is reasonably
507 consistent with ImageX which actually uses "fast" (XPRESS) compression
508 by default. In those cases, use '--compress=maximum' to explicitly
509 capture a WIM image using the new (slower but better) LZX compressor.
511 The '--compress-slow' option still exists to `wimlib-imagex optimize',
512 but its new behavior is to tweak the new LZX compressor even more to
513 produce an even better compression ratio at the cost of more time spent
516 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
517 which recompresses the WIM file using the specified compression TYPE.
518 The new library API function used for this is
519 wimlib_set_output_compression_type().
521 Added the wimlib_get_xml_data() function to allow library clients to
522 easily retrieve the raw XML data from a WIM file if needed.
524 Fixed a bug that could cause an error code to be incorrectly returned
525 when writing XML data containing a <WINDOWS> element.
527 Mounted WIM images will now correctly show the default file stream even
528 if appears in the alternate data stream entries of the corresponding WIM
532 Added a new experimental LZX compressor which can be enabled by passing
533 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
534 optimize'. (The latter is only applicable if the WIM is already
535 LZX-compressed and the '--recompress' option is also given.) The
536 experimental compressor is much slower but compresses the data slightly
537 more --- currently usually to within a fraction of a percent of the
538 results from WIMGAPI/ImageX.
540 A workaround has been added for compatibility with versions of WinPE
541 that interpret alternate data stream entries in the boot WIM
544 An alignment bug that caused a crash in the LZX decompressor on some
547 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
548 the WIM header when restoring the previous state of a WIM it failed to
551 Added a workaround to avoid an access denied error on Windows when
552 replacing a WIM file that another process has opened.
555 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
556 needed to be handled.
558 A bug in the interpretation of negative IMAGE indices in the
559 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
560 `wimlib-imagex append' has been fixed.
562 A workaround has been added to successfully apply security descriptors
563 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
564 2013.1.13 or earlier.
566 `wimlib-imagex capture' can now accept the '--delta-from' option
570 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
571 to standard output and applying images from standard input, but they are
572 not compatible with Microsoft's software and are not created by default.
573 See the documentation for --pipable flag of `wimlib-imagex capture' for
576 To better support incremental backups, added support for declaring an
577 image as a modified form of another image. See the documentation for
578 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
581 Added supported for "delta" WIMs. See the documentation for the
582 '--delta-from' option of `wimlib-imagex capture'.
584 The library support for managing split WIMs has been changed to support
585 other arrangements, such as delta WIMs, and be easier to use. This
586 change is visible in `wimlib-imagex', which also can now accept the
587 '--ref' option multiple times, and also now supports "delta" WIMs as
590 wimlib now preserves WIM integrity tables by default, even if
591 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
592 behavior of `wimlib-imagex' whenever the WIM being operated on contains
593 an integrity table and the '--check' option is not specified.
595 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
596 (when --compress is not specified). This provides the best compression
597 ratio by default, which is usually what is desired, at a cost of some
600 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
601 is the command as in `wimlib-imagex COMMAND'; for example, it can be
602 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
603 appropriate hard links are created in UNIX installations of
604 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
605 batch files that emulate this behavior are generated.
607 Security descriptors are now extracted correctly on Windows.
609 Fixed archiving DOS names in NTFS-3g capture mode.
611 The extraction code has been rewritten and it will now be easier to
612 support new features on all supported backends (currently Win32, UNIX,
613 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
614 now supported on all backends, not just UNIX.
616 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
617 than the WAIK itself.
619 wimlib_global_init() now, by default, attempts to acquire additional
620 privileges on Windows, so library clients need not do this.
622 This update bumps the shared library version number up to 9, since it is
623 not binary compatibible with previous releases.
626 Fixed bug in `wimlib-imagex export' that made it impossible to export an
627 image from a WIM that is readonly at the filesystem level.
629 Return error code rather than segfaulting when trying to list files from
630 a non-first part of a split WIM.
632 Joining a WIM will now preserve the RP_FIX and READONLY flags.
635 On Windows, paths given to wimlib-imagex are now treated case
638 Improved behavior regarding invalid filenames; in particular, on
639 Windows, wimlib-imagex will, when extracting, now omit (with an option
640 to override this default) filenames differing only in case, or filenames
641 containing characters not valid on Windows.
643 On Windows, wimlib now supports capturing and extracting long paths
644 (longer than the so-called MAX_PATH).
646 On Windows, `wimlib-imagex update' now acquires proper privileges when
647 running as an Administrator.
649 `wimlib-imagex update' will now complain if no image is specified when
650 trying to update a multi-image WIM.
652 `wimlib-imagex update' now supports specifying a single update command
653 directly on the command line using the --command option.
655 wimlib-imagex will now choose different units for progress messages,
656 depending on the amount of data that needs to be processed.
658 `wimlib-imagex append' will now generate a unique WIM image name if no
659 name is specified and the defaulted name already exists in the WIM.
661 wimlib now allows you to create unnamed WIM images, which can then only
662 be referred to by index.
664 wimlib now allows you to explicitly declare you want write access to a
665 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
668 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
671 Progress callbacks have been added to wimlib's wimlib_update_image()
674 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
675 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
678 NTFS-3g capture now only warns about two conditions previously treated
681 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
684 wimlib now correctly detects and returns an error when reading a WIM
685 image with a cyclic directory structure. (Fun fact: such a WIM will
686 crash Microsoft's software.)
689 Added new "extract" and "update" subcommands to wimlib-imagex, along
690 with associated APIs in the library. These commands are intended mainly
691 for Windows use but can be used on UNIX as well.
693 Many documentation improvements.
695 Fixed a bug in the Windows build where relative symbolic links were not
696 captured in reparse-point fixup mode.
698 Fixed a bug in the Windows build where file handles were left open to
699 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
701 Fixed a bug in the Windows build of wimlib-imagex where globbing
702 split-WIM parts could cause the program to crash.
704 Fixed a bug where the creation time of WIM images would be shown instead
705 of the last modification time.
707 With the Windows build it is now possible to restore a WIM containing
708 symbolic links as a non-Administrator; however you will receive warnings
709 about not being able to extract the symbolic links.
712 Capturing a WIM image should now be significantly faster in most cases
713 due to improved use of the operating system's cache and avoiding reading
714 files twice whenever possible.
716 The Windows build should now work on Windows XP.
718 The Windows build now supports capturing and restoring hidden,
719 compressed, sparse, and encrypted files.
721 The Windows build now supports capturing and applying WIM images from
722 filesystems other than NTFS (with some reduced functionality).
724 The Windows build now extracts short names correctly.
726 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
727 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
728 capture' and `wimlib-imagex apply'.
730 The performance of splitting and joining WIMs should be slightly
733 The LZX and XPRESS compression and decompression functions are now
734 exported from the library.
737 Improvements and bugfixes for the Windows build.
739 Added --strict-acls options.
741 Fixed the way that wimlib determines the order of images in the WIM.
744 Since wimlib can now be used on Windows, wimlib's implementation of
745 ImageX has been renamed to wimlib-imagex to avoid confusion with
746 Microsoft's implementation of ImageX, which would have the same file
747 name ("imagex.exe"). If you really don't like this you can pass the
748 --with-imagex-progname option to `configure' to choose a different name,
749 or even simply rename the binary yourself (but the former way will
750 configure the man pages to use the chosen name).
752 Various bugs fixed in the Windows build. Mainly to do with capturing
753 and restoring alternate data streams correctly in weird cases, and
754 requesting the correct privileges when opening files. Also added the
755 --noacls options to wimlib-imagex capture, append, and apply.
757 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
758 dynamically loaded, so this may make the library compatible with Windows
759 XP (however, there may still be other problems).
762 Added experimental support for native Windows builds. Binaries can be
763 downloaded from the SourceForge page.
765 --source-list option added to `imagex capture' and `imagex append'.
767 Better support for different character encodings.
770 Storing UNIX file owners, groups, and modes in WIM images is now
771 possible using `imagex capture' with the --unix-data flag.
773 Minor bug fixes and documentation fixes.
776 NTFS capture: Fixed capturing duplicate reparse points.
778 NTFS capture: Capture first unnamed stream if there are more than one
779 (print warning instead of error).
781 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
784 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
787 Update to work with ntfs-3g version 2013.1.13.
790 Fixed truncating file to shorter but non-zero length on read-write
793 Various code cleanups and minor documentation fixes.
796 LZX and XPRESS decompression have received some additional optimizations
797 and should now be even faster. (Although, they were already pretty
798 fast--- much faster than typical I/O speeds.)
800 Fixed a bug introduced in v1.2.1 that would cause a directory tree
801 containing hard links to be captured incorrectly in some cases.
804 By default, unmounting a read-write mounted WIM with 'imagex unmount
805 --commit' will now change the WIM in-place without needing to write the
806 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
809 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
810 for a response from the daemon servicing the mounted WIM. Instead,
811 every second 'imagex unmount' will check if the daemon is still alive,
812 and keep waiting if so, otherwise terminate with an error.
814 'imagex unmount --commit' on a read-write mounted WIM will now print
815 progress information regarding the writing of new or modified streams
816 the WIM, just like when capturing or appending a WIM.
818 A small change has been made to XPRESS compression and it should improve
819 the compression ratio slightly.
821 A change was made that may improve performance slightly when applying a
822 WIM image to a NTFS volume.
824 Microsoft has managed to introduce even more bugs into their software,
825 and now the WIMs for Windows 8 have incorrect (too low) reference counts
826 for some streams. This is unsafe because such streams can be removed
827 when they are in actuality still referenced in the WIM (perhaps by a
828 different image). wimlib will now work around this problem by fixing
829 the stream reference counts. This is only done when wimlib_delete_image() is
830 called ('imagex delete') or when wimlib_mount_image() is called with
831 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
832 requires reading the metadata for all images in the WIM, so this will
833 make these operations noticably slower on WIMs with multiple images.
835 Various other bugfixes.
838 Appending images to a WIM is now be done by default without re-building
839 the whole WIM. Use the --rebuild flag to get the old behavior (which
840 was to re-build the entire WIM when a new image is appended).
842 A new command `imagex optimize' is now available to manually re-build a
843 WIM that has wasted space due to repeated appends.
845 Progress information has been improved, and now arbitrary callback
846 functions can be used to show the progress of a WIM operation.
848 A possible bug with changing the bootable image of a WIM was fixed.
850 Some advisory locking is now done to prevent two processes from
851 modifying a WIM at the same time (but only in some cases). For example,
852 you cannot mount two images from a WIM read-write at the same time.
854 Some functions have been reorganized:
855 * wimlib_mount() renamed to wimlib_mount_image().
856 * wimlib_unmount() renamed to wimlib_unmount_image().
857 * wimlib_overwrite_xml_and_header() removed as
858 wimlib_overwrite() suffices now.
859 * wimlib_apply_image_to_ntfs_volume() removed as
860 wimlib_extract_image() suffices now.
861 * wimlib_add_image_from_ntfs_volume() removed as
862 * wimlib_add_image() suffices now.
864 Previously, the soname of libwim.so has been 0.0.0, despite many
865 interface changes. The soname is now updated to 1.0.0 and will now be
866 updated each release.
869 Resources will now be compressed using multiple threads by default.
870 (This applies to `imagex capture', `imagex append', and `imagex
873 Some performance improvements in mounted WIMs.
875 More progress information is shown when capturing a WIM.
878 Lots of minor fixes, code cleanups, and some documentation updates.
879 Nothing in particular is really noteworthy.
882 LZX and XPRESS compression improvements.
884 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
885 Link Bytes of the WIM.
888 Fixed bug when capturing NTFS file with multiple named data streams.
890 Internally, we are now using inode structures, even though these don't
891 appear literally in the WIM file. This simplifies some of the code
892 (mainly for WIM mounting) and likely fixed a few problems, although it
896 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
900 Enough changes to call it version 1.0.0!
902 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
903 to a NTFS volume, is now supported.
905 Hard links and symbolic links have much improved support. They are
906 supported for WIM capture, WIM application, and mounted WIMs (you can
907 even make them on read-write mounted WIMs).
909 Alternate data streams are now supported on mounted WIMs through an
910 xattr or a Windows-style stream interface. Also they are supported when
911 capturing a WIM from NTFS or applying a WIM to NTFS.
913 Split WIMs are better supported. You may now apply an image directly
914 from a split WIM, mount an image from a split WIM read-only, or export
915 an image from a split WIM.
917 Using a capture configuration file is now supported (but not fully yet).
919 SHA1 message digests are checked in more places, so we can make sure
920 applied and captured data is correct.
922 Man pages have been updated and consolidated.
925 Fixed segfault when unmounting read-only WIM.
928 Support for joining and splitting WIMs.
929 Also, security data is now preserved by default.
932 Can now build with older gcc and system headers, like on CentOS 5.
935 Fixed bug that made it impossible to overwrite files in read-write
939 Write byte-order mark before WIM XML data. (imagex.exe requires this to
