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