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.
11 Clarified the main license text and updated public domain dedications
12 for certain files to be more thorough.
15 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
17 Reduced memory usage when exporting large numbers of WIM images.
19 Non UTF-8 locales are now detected correctly.
21 Addressed compiler warnings and enabled "silent" make rules by default.
23 Windows-specific updates:
24 Fixed a bug where duplicate backslashes could be generated in
25 link targets when extracting symbolic links and junctions.
27 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
28 work if their full path contained a space.
30 Fixed bugs related to scanning SMB filesystems.
32 Added warning message about known issue with WindowsApps folder.
34 Added instructions for building from source on Windows.
36 VSS support is no longer marked "experimental".
38 Added missing license file for libdivsufsort-lite.
41 Added experimental support for Windows VSS (Volume Shadow Copy Service).
42 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
43 create and use a temporary VSS snapshot when capturing a WIM image.
45 Implemented setting of Windows-specific XML information, such as
46 architecture, system root, and version details. This information is now
47 automatically set in newly captured WIM images, when appropriate.
49 Improved performance of directory tree scans on Windows.
51 On Windows, to improve capture performance, wimlib now sometimes opens
52 files by inode number rather than by path. This is enabled for
53 wimcapture and wimappend, but for now other applications have to opt-in.
55 The progress messages printed by wimlib-imagex while writing WIM files
56 have been slightly tweaked.
58 Progress information for directory tree scans now counts all hard links.
59 Also, on Windows "\\?\" is no longer stripped from the current path.
61 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
62 'wiminfo'. This option lets you assign values to elements in a WIM
63 file's XML document by name.
65 The wimlib_get_image_property() and wimlib_set_image_property() API
66 functions now support numerically indexed elements.
68 Fixed a bug where, on Windows, wimlib would change the security
69 descriptor of the target directory of an extraction even when the
70 '--no-acls' option was specified.
73 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
74 some Microsoft software would not correctly recognize data in the
77 Made some small improvements to the compression algorithms:
78 LZX compression ratio was slightly improved.
79 XPRESS compression ratio and speed was slightly improved.
80 LZMS compression speed was slightly improved.
82 Improved handling of WIM XML data. wimlib no longer drops unrecognized
83 elements when exporting images. In addition, two API functions were
84 added for better access to elements in the XML document:
85 wimlib_get_image_property() and wimlib_set_image_property().
87 Added support for (unsafe) in-place compaction of WIM files.
89 Improved performance of image export by reusing metadata resources
90 instead of always rebuilding and recompressing them.
92 Improved performance of wimlib_update_image() by delaying the update to
93 the WIM's XML document until a write is requested.
95 On Windows, the target of an extraction may now be a reparse point
96 (which will be dereferenced).
98 On Windows, wimlib now correctly restores non-Microsoft reparse points.
99 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
101 On Windows, wimlib now has improved performance when archiving files
102 from a filesystem backed by a WIM (a "WIMBoot" setup).
104 Several improvements to System Compression (compact mode) support:
106 wof.sys (or wofadk.sys) is now automatically attached to the
107 target volume if needed.
109 Compact-mode extractions now work correctly with wofadk.sys on
110 older versions of Windows.
112 For compatibility with the Windows bootloader, the requested
113 compression format now is overridden on certain files.
115 Other minor bugfixes.
118 This release primarily contains various minor bug fixes and
119 improvements, including:
121 Improved handling of deep directory structures.
123 Fixed a bug where on 32-bit systems, the library could enter an
124 infinite loop if a WIM file was malformed in a specific way.
126 Added a workaround for a case where libntfs-3g may report
127 duplicate streams in an NTFS file.
129 Windows symbolic links and junctions in mounted WIM images are
130 now automatically rewritten to be valid in the mounted location.
132 Reparse point fixes: correctly handle the "ReparseReserved"
133 field, and correctly handle "empty" (data-less) reparse points.
135 On Windows, wimlib now acquires SeManageVolumePrivilege, which
136 is needed to create externally backed files using the
139 Improved validation of filenames.
141 Improved LZMS decompression speed.
143 The configure script now honors alternate pkg-config settings.
145 Links have been updated to point to the new website.
147 In addition, experimental support has been added for compressing
148 extracted files using System Compression on Windows 10. This
149 functionality is available through the new '--compact' option to
150 'wimapply' and 'wimextract' as well as new library flags.
153 Fixed a bug in the LZX decompressor: malicious input data could cause
154 out of bounds writes to memory (since wimlib v1.2.2).
156 The output of the 'wiminfo' command now consolidates various boolean
157 flags (such as "Relative path junction") into a single line.
159 A file can now have both an unnamed data stream ("file contents") and a
160 reparse point stream. Such files can exist as a result of the use of
161 certain Windows features, such as offline storage, including "OneDrive".
162 wimlib will now store and restore both streams on Windows as well as in
163 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
165 On Windows, named data streams of encrypted files are no longer stored
166 twice in WIM archives.
168 On Windows, named data streams are now correctly extracted to existing
169 "readonly" directories. Before, an error would be reported.
171 On Windows, it is now possible to do a "WIMBoot mode" extraction with
172 non-standalone WIMs such as delta WIMs.
174 On Windows, when doing an extraction in "WIMBoot mode", files larger
175 than 4 gigabytes are now never extracted as externally backed. This
176 works around a bug in Microsoft's "WOF" driver.
178 The '--enable-verify-compression' configure option has been removed. If
179 you want to verify a WIM file, use the 'wimverify' program.
181 The way the "file count", "directory count", "total bytes", and "hard
182 link bytes" image statistics (stored in the WIM XML data) is calculated
183 has been slightly changed.
185 In mounted WIM images, the disk usage provided for each file (st_blocks)
186 is now the compressed size rather than the uncompressed size.
188 The performance of the NTFS-3g and Windows capture modes has been
191 On UNIX-like systems, symbolic links whose targets contain the backslash
192 character are now handled correctly (losslessly).
195 Improved the LZX compressor. It is now 15-20% faster than before and
196 provides a slightly better compression ratio.
198 Improved the LZMS compressor. It now provides a compression ratio
199 slightly better than WIMGAPI while still being faster and using slightly
202 The compression chunk size in solid resources, e.g. when capturing or
203 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
204 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
205 better compression ratio and is the same value that WIMGAPI uses. The
206 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
207 lower than WIMGAPI's memory usage, but if it is too much, it is still
208 possible to choose a lower value, e.g. with the '--solid-chunk-size'
209 option to wimlib-imagex.
211 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
212 accept the 'K', 'M', and 'G' suffixes.
214 Files are now sorted by name extension when creating a solid WIM file.
216 Fixed various issues related to capture/apply of EFS-encrypted files on
219 The file list printed by 'wimdir' is now sorted by the platform-specific
220 case sensitivity setting, rather than always case sensitively. This
221 also affects the library function wimlib_iterate_dir_tree().
223 On Windows, some error and warning messages have been improved.
226 The Windows binary distribution no longer contains third party DLLs.
227 These dependencies are instead compiled directly into the libwim DLL.
229 Added more fixes for wimlib on non-x86 architectures such as ARM.
231 Extracting files to a Windows PE in-memory filesystem no longer fails if
232 the target files do not yet exist.
234 Improved the performance of XPRESS compression and LZMS decompression.
236 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
237 It will automatically be faster on newer Intel and AMD processors.
239 Removed the --with-imagex-progname and --enable-more-assertions
243 Fix for very slow export from solid WIM / ESD files.
245 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
247 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
248 may use this to treat some types of errors as non-fatal.
250 The library now permits making in-memory changes to a WIMStruct backed
251 by a read-only WIM file.
253 Fixes for "WIMBoot" extraction mode (Windows only):
255 When not using the WOF driver, extraction no longer fails if the
256 disk containing the WIM file has too many partitions.
258 When matching patterns in [PrepopulateList], all hard links of
259 each file are now considered.
261 The system registry files are now automatically treated as being
262 in [PrepopulateList].
264 Added a hack to try to work around an intermittent bug in
265 Microsoft's WOF (Windows Overlay Filesystem) driver.
268 Made more improvements to the XPRESS, LZX, and LZMS compressors.
270 A number of improvements to the Windows port:
272 Fixes for setting short filenames.
274 Faster "WIMBoot" extraction.
276 Updated and slimmed down the dependent DLLs.
278 ACL inheritence bits are now restored.
280 Mandatory integrity labels are now backed up and restored.
282 Added a workaround for an issue where in rare cases, wimlib could create
283 a compressed data stream that could not be read correctly by Windows
284 after an extraction in "WIMBoot" mode.
287 Added file count progress data for
288 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
289 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
291 Added support for testing file exclusions via the user-provided
294 Some documentation improvements.
296 Made some clarifications to the license text in the COPYING file.
299 Made more improvements to the XPRESS, LZX, and LZMS compressors.
301 The default compression mode for wimcapture is now LZX compression in
302 its default mode, which is the same as '--compress=maximum'.
304 You can now specify an optional integer compression level to the
305 '--compress' option; e.g. '--compress=lzx:75'.
307 Made a minor change to the LZMS compressor and decompressor to fix an
308 incompatibility with the Microsoft implementation. In the unlikely
309 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
310 earlier and a checksum error is reported when extracting files from it
311 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
314 Added 'verify' subcommand to wimlib-imagex.
316 Notable library changes:
318 Custom compressor parameters have been removed from the library
319 in favor of the simpler level-based API.
321 Decompressor parameters have been removed entirely.
323 Library users can now specify a custom file for warning and
324 error messages to be sent to, rather than the default of
327 New progress messages:
328 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
329 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
331 New function: wimlib_verify_wim().
334 Improved compression, decompression, and extraction performance.
336 Improved compatibility with version 3584 WIM / ESD files:
337 - Add support for reading and writing multiple solid blocks per
338 archive, which WIMGAPI/DISM can create when appending an image.
339 - Correctly create solid blocks larger than 4 GiB.
341 'add' commands passed to wimupdate will now replace existing
342 nondirectory files by default. Use the --no-replace option to get the
345 The license for the library now contains an exception that allows using
346 it under the LGPL. See the COPYING file for details.
348 In reparse-point fixup mode (the default for capture), symbolic links
349 and junctions that point outside the tree being captured are no longer
350 excluded from capture.
352 Added support for "WIMBoot" capture and extraction. See the
353 documentation for the new '--wimboot' option to wimcapture and wimapply
354 for more information.
356 On UNIX-like systems, you can now backup and restore device nodes, named
357 pipes, and sockets. In addition, 32-bit user and group IDs are now
360 The way that UNIX data is stored in WIM files has been changed. If you
361 captured any WIMs with the --unix-data option, to upgrade them you'll
362 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
363 re-capture them with --unix-data using this version.
365 wimlib now understands tagged metadata items, such as object IDs, that
366 can be stored in WIM directory entries.
368 Removed the --hardlink and --symlink options to wimapply, since I don't
369 think they are too useful and they got in the way of improving the code.
371 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
373 The 'mkwinpeimg' script now supports writing the ISO image to standard
376 The <ARCH> element in WIM XML data is now exported correctly.
378 On Windows, sparse file attributes are no longer set on extracted files.
379 Oddly enough, this actually saves disk space in some cases.
381 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
382 supported. Mounting WIM images now always requires extended attribute
383 support. Use --without-fuse to disable support for mounting WIM images;
384 this will also disable the need for extended attribute support.
386 Configuring with --enable-ssse3-sha1 now works correctly.
388 The shared library version has been bumped up. The main
389 incompatibilities are:
391 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
392 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
395 - User-provided progress functions are now registered using a
396 separate function, wimlib_register_progress_function(). The
397 'progress_func' argument to many functions no longer exists.
399 - The return value from user-provided progress functions is now
402 - A context argument has been added to the prototype of
403 user-provided progress functions.
405 - 'struct wimlib_capture_config' has been removed. The library
406 now takes the path to the configuration file directly. This
407 affects wimlib_add_image(), wimlib_add_image_multisource(),
408 and wimlib_update_image(). However, a NULL value passed in
409 the argument retains the same meaning.
411 - Removed deprecated functions: some (de)compression functions,
412 wimlib_extract_files(), and wimlib_print_metadata().
414 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
415 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
416 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
418 - Removed some progress messages:
419 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
420 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
421 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
424 - Removed some error codes. Numbering stays the same.
426 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
427 WIMLIB_UNMOUNT_FLAG_FORCE.
429 - WIM paths passed to progress functions now have a leading
433 Case-insensitive comparisons of strings (e.g. filenames) containing
434 UTF-16 codepoints above 32767 are now done correctly.
436 Fixed build failure on Mac OS X.
438 wimunmount now provides the '--new-image' option to cause changes to a
439 read-write mounted image to be committed as a new image rather than as
440 an update of the mounted image. (The corresponding new library flag is
441 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
443 The LZMS ("recovery") compression chunk size, or "dictionary size", may
444 now be up to 1 GiB (1,073,741,824 bytes).
446 The performance of LZX ("maximum") and LZMS ("recovery") compression
447 with large chunk sizes has been slightly improved.
450 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
451 decompressed correctly.
453 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
454 occurred in an unlikely case, and due to validity checks it did not
455 affect successfully created archives.
457 Fixed a minor compatibility issue with the LZMS compressor and
458 decompressor. This is *not* the default compression type and was only
459 introduced in v1.6.0. In the unlikely event that you created an
460 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
461 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
464 Memory usage for LZMS and LZX compression has been decreased.
466 wimextract now allows wildcard characters in paths specified on the
467 command line. Also, the '--strict-wildcards' option has been removed
468 and replaced with the inverse option '--nullglob'. See the
469 documentation for wimextract for more details and changes.
471 The wimlib_extract_files() function is now considered deprecated in
472 favor of wimlib_extract_paths().
474 Fixed more permissions problems when extracting files on Windows.
476 A new '--no-attributes' option has been added to wimapply and
477 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
479 The default chunk size is now set correctly when changing the
480 compression type of a WIM, for example with 'wimoptimize'.
482 The '--metadata' option to wiminfo has been replaced with the
483 '--detailed' option to wimdir.
485 In relevant wimlib-imagex commands, '--solid' may now be used as an
486 alias for '--pack-streams'.
489 Support for extracting and updating the new version 3584 WIMs has been
490 added. These WIMs typically pack many streams ("files") together into a
491 single compressed resource, thereby saving space. This degrades the
492 performance of random access (such as that which occurs on a mounted
493 image), but optimizations have been implemented for extraction. These
494 new WIM files also typically use a new compression format (LZMS), which
495 is similar to LZMA and can offer a better compression ratio than LZX.
496 These new WIM files can be created using `wimcapture' with
497 the '--compress=lzms --pack-streams' options. Note: this new WIM format
498 is used by the Windows 8 web downloader, but important segments of the
499 raw '.esd' files are encrypted, so wimlib will not be able to extract
500 such files until they are first decrypted.
502 wimlib now supports extracting files and directories from a WIM image
503 based on a "listfile" that itself contains the list of paths to extract.
504 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
505 and for the library itself, the new APIs are wimlib_extract_pathlist()
506 and wimlib_extract_paths(). Path globs containing wildcard characters
509 For searching WIM files, wimlib now has configurable case sensitivity.
510 The default on Windows is still case-insensitive and the default on
511 UNIX-like systems is still case-sensitive, but this can be overridden
512 on either platform through flags to wimlib_global_init(). For
513 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
514 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
517 Support for compression chunk sizes greater than the default of 32768
518 bytes has been added. A larger chunk size typically results in a better
519 compression ratio. However, the MS implementation is seemingly not
520 compatible with all chunk sizes, especially for LZX compression, so the
521 defaults remain unchanged, with the exception of the new LZMS-compressed
522 WIMs, which use a larger chunk size by default.
524 The compression/decompression API exported by wimlib has been changed.
525 Now one set of functions handles all supported compression formats.
527 `wimcapture' and `wimappend' will now display the progress of scanning
528 the directory tree to capture, in addition to the progress of writing
529 data to the WIM. The '--verbose' option no longer does anything. The
530 library API change for this is the addition of several members to
531 `struct wimlib_progress_info_scan' available to progress callbacks.
533 `mkwinpeimg' now correctly handles the '--start-script' option when the
534 start script is not in the working directory.
536 Sequential extraction, previously requested by using
537 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
538 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
539 behavior (extract in file order).
542 The new LZX compressor added in v1.5.2 has been improved and is now
543 enabled by default, except when `wimcapture' or `wimappend' is run
544 *without* the '--compress' option, in which case the faster LZX
545 compressor is used (the same as before). This behavior is reasonably
546 consistent with ImageX which actually uses "fast" (XPRESS) compression
547 by default. In those cases, use '--compress=maximum' to explicitly
548 capture a WIM image using the new (slower but better) LZX compressor.
550 The '--compress-slow' option still exists to `wimlib-imagex optimize',
551 but its new behavior is to tweak the new LZX compressor even more to
552 produce an even better compression ratio at the cost of more time spent
555 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
556 which recompresses the WIM file using the specified compression TYPE.
557 The new library API function used for this is
558 wimlib_set_output_compression_type().
560 Added the wimlib_get_xml_data() function to allow library clients to
561 easily retrieve the raw XML data from a WIM file if needed.
563 Fixed a bug that could cause an error code to be incorrectly returned
564 when writing XML data containing a <WINDOWS> element.
566 Mounted WIM images will now correctly show the default file stream even
567 if appears in the alternate data stream entries of the corresponding WIM
571 Added a new experimental LZX compressor which can be enabled by passing
572 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
573 optimize'. (The latter is only applicable if the WIM is already
574 LZX-compressed and the '--recompress' option is also given.) The
575 experimental compressor is much slower but compresses the data slightly
576 more --- currently usually to within a fraction of a percent of the
577 results from WIMGAPI/ImageX.
579 A workaround has been added for compatibility with versions of WinPE
580 that interpret alternate data stream entries in the boot WIM
583 An alignment bug that caused a crash in the LZX decompressor on some
586 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
587 the WIM header when restoring the previous state of a WIM it failed to
590 Added a workaround to avoid an access denied error on Windows when
591 replacing a WIM file that another process has opened.
594 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
595 needed to be handled.
597 A bug in the interpretation of negative IMAGE indices in the
598 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
599 `wimlib-imagex append' has been fixed.
601 A workaround has been added to successfully apply security descriptors
602 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
603 2013.1.13 or earlier.
605 `wimlib-imagex capture' can now accept the '--delta-from' option
609 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
610 to standard output and applying images from standard input, but they are
611 not compatible with Microsoft's software and are not created by default.
612 See the documentation for --pipable flag of `wimlib-imagex capture' for
615 To better support incremental backups, added support for declaring an
616 image as a modified form of another image. See the documentation for
617 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
620 Added supported for "delta" WIMs. See the documentation for the
621 '--delta-from' option of `wimlib-imagex capture'.
623 The library support for managing split WIMs has been changed to support
624 other arrangements, such as delta WIMs, and be easier to use. This
625 change is visible in `wimlib-imagex', which also can now accept the
626 '--ref' option multiple times, and also now supports "delta" WIMs as
629 wimlib now preserves WIM integrity tables by default, even if
630 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
631 behavior of `wimlib-imagex' whenever the WIM being operated on contains
632 an integrity table and the '--check' option is not specified.
634 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
635 (when --compress is not specified). This provides the best compression
636 ratio by default, which is usually what is desired, at a cost of some
639 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
640 is the command as in `wimlib-imagex COMMAND'; for example, it can be
641 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
642 appropriate hard links are created in UNIX installations of
643 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
644 batch files that emulate this behavior are generated.
646 Security descriptors are now extracted correctly on Windows.
648 Fixed archiving DOS names in NTFS-3g capture mode.
650 The extraction code has been rewritten and it will now be easier to
651 support new features on all supported backends (currently Win32, UNIX,
652 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
653 now supported on all backends, not just UNIX.
655 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
656 than the WAIK itself.
658 wimlib_global_init() now, by default, attempts to acquire additional
659 privileges on Windows, so library clients need not do this.
661 This update bumps the shared library version number up to 9, since it is
662 not binary compatibible with previous releases.
665 Fixed bug in `wimlib-imagex export' that made it impossible to export an
666 image from a WIM that is readonly at the filesystem level.
668 Return error code rather than segfaulting when trying to list files from
669 a non-first part of a split WIM.
671 Joining a WIM will now preserve the RP_FIX and READONLY flags.
674 On Windows, paths given to wimlib-imagex are now treated case
677 Improved behavior regarding invalid filenames; in particular, on
678 Windows, wimlib-imagex will, when extracting, now omit (with an option
679 to override this default) filenames differing only in case, or filenames
680 containing characters not valid on Windows.
682 On Windows, wimlib now supports capturing and extracting long paths
683 (longer than the so-called MAX_PATH).
685 On Windows, `wimlib-imagex update' now acquires proper privileges when
686 running as an Administrator.
688 `wimlib-imagex update' will now complain if no image is specified when
689 trying to update a multi-image WIM.
691 `wimlib-imagex update' now supports specifying a single update command
692 directly on the command line using the --command option.
694 wimlib-imagex will now choose different units for progress messages,
695 depending on the amount of data that needs to be processed.
697 `wimlib-imagex append' will now generate a unique WIM image name if no
698 name is specified and the defaulted name already exists in the WIM.
700 wimlib now allows you to create unnamed WIM images, which can then only
701 be referred to by index.
703 wimlib now allows you to explicitly declare you want write access to a
704 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
707 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
710 Progress callbacks have been added to wimlib's wimlib_update_image()
713 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
714 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
717 NTFS-3g capture now only warns about two conditions previously treated
720 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
723 wimlib now correctly detects and returns an error when reading a WIM
724 image with a cyclic directory structure. (Fun fact: such a WIM will
725 crash Microsoft's software.)
728 Added new "extract" and "update" subcommands to wimlib-imagex, along
729 with associated APIs in the library. These commands are intended mainly
730 for Windows use but can be used on UNIX as well.
732 Many documentation improvements.
734 Fixed a bug in the Windows build where relative symbolic links were not
735 captured in reparse-point fixup mode.
737 Fixed a bug in the Windows build where file handles were left open to
738 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
740 Fixed a bug in the Windows build of wimlib-imagex where globbing
741 split-WIM parts could cause the program to crash.
743 Fixed a bug where the creation time of WIM images would be shown instead
744 of the last modification time.
746 With the Windows build it is now possible to restore a WIM containing
747 symbolic links as a non-Administrator; however you will receive warnings
748 about not being able to extract the symbolic links.
751 Capturing a WIM image should now be significantly faster in most cases
752 due to improved use of the operating system's cache and avoiding reading
753 files twice whenever possible.
755 The Windows build should now work on Windows XP.
757 The Windows build now supports capturing and restoring hidden,
758 compressed, sparse, and encrypted files.
760 The Windows build now supports capturing and applying WIM images from
761 filesystems other than NTFS (with some reduced functionality).
763 The Windows build now extracts short names correctly.
765 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
766 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
767 capture' and `wimlib-imagex apply'.
769 The performance of splitting and joining WIMs should be slightly
772 The LZX and XPRESS compression and decompression functions are now
773 exported from the library.
776 Improvements and bugfixes for the Windows build.
778 Added --strict-acls options.
780 Fixed the way that wimlib determines the order of images in the WIM.
783 Since wimlib can now be used on Windows, wimlib's implementation of
784 ImageX has been renamed to wimlib-imagex to avoid confusion with
785 Microsoft's implementation of ImageX, which would have the same file
786 name ("imagex.exe"). If you really don't like this you can pass the
787 --with-imagex-progname option to `configure' to choose a different name,
788 or even simply rename the binary yourself (but the former way will
789 configure the man pages to use the chosen name).
791 Various bugs fixed in the Windows build. Mainly to do with capturing
792 and restoring alternate data streams correctly in weird cases, and
793 requesting the correct privileges when opening files. Also added the
794 --noacls options to wimlib-imagex capture, append, and apply.
796 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
797 dynamically loaded, so this may make the library compatible with Windows
798 XP (however, there may still be other problems).
801 Added experimental support for native Windows builds. Binaries can be
802 downloaded from the SourceForge page.
804 --source-list option added to `imagex capture' and `imagex append'.
806 Better support for different character encodings.
809 Storing UNIX file owners, groups, and modes in WIM images is now
810 possible using `imagex capture' with the --unix-data flag.
812 Minor bug fixes and documentation fixes.
815 NTFS capture: Fixed capturing duplicate reparse points.
817 NTFS capture: Capture first unnamed stream if there are more than one
818 (print warning instead of error).
820 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
823 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
826 Update to work with ntfs-3g version 2013.1.13.
829 Fixed truncating file to shorter but non-zero length on read-write
832 Various code cleanups and minor documentation fixes.
835 LZX and XPRESS decompression have received some additional optimizations
836 and should now be even faster. (Although, they were already pretty
837 fast--- much faster than typical I/O speeds.)
839 Fixed a bug introduced in v1.2.1 that would cause a directory tree
840 containing hard links to be captured incorrectly in some cases.
843 By default, unmounting a read-write mounted WIM with 'imagex unmount
844 --commit' will now change the WIM in-place without needing to write the
845 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
848 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
849 for a response from the daemon servicing the mounted WIM. Instead,
850 every second 'imagex unmount' will check if the daemon is still alive,
851 and keep waiting if so, otherwise terminate with an error.
853 'imagex unmount --commit' on a read-write mounted WIM will now print
854 progress information regarding the writing of new or modified streams
855 the WIM, just like when capturing or appending a WIM.
857 A small change has been made to XPRESS compression and it should improve
858 the compression ratio slightly.
860 A change was made that may improve performance slightly when applying a
861 WIM image to a NTFS volume.
863 Microsoft has managed to introduce even more bugs into their software,
864 and now the WIMs for Windows 8 have incorrect (too low) reference counts
865 for some streams. This is unsafe because such streams can be removed
866 when they are in actuality still referenced in the WIM (perhaps by a
867 different image). wimlib will now work around this problem by fixing
868 the stream reference counts. This is only done when wimlib_delete_image() is
869 called ('imagex delete') or when wimlib_mount_image() is called with
870 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
871 requires reading the metadata for all images in the WIM, so this will
872 make these operations noticably slower on WIMs with multiple images.
874 Various other bugfixes.
877 Appending images to a WIM is now be done by default without re-building
878 the whole WIM. Use the --rebuild flag to get the old behavior (which
879 was to re-build the entire WIM when a new image is appended).
881 A new command `imagex optimize' is now available to manually re-build a
882 WIM that has wasted space due to repeated appends.
884 Progress information has been improved, and now arbitrary callback
885 functions can be used to show the progress of a WIM operation.
887 A possible bug with changing the bootable image of a WIM was fixed.
889 Some advisory locking is now done to prevent two processes from
890 modifying a WIM at the same time (but only in some cases). For example,
891 you cannot mount two images from a WIM read-write at the same time.
893 Some functions have been reorganized:
894 * wimlib_mount() renamed to wimlib_mount_image().
895 * wimlib_unmount() renamed to wimlib_unmount_image().
896 * wimlib_overwrite_xml_and_header() removed as
897 wimlib_overwrite() suffices now.
898 * wimlib_apply_image_to_ntfs_volume() removed as
899 wimlib_extract_image() suffices now.
900 * wimlib_add_image_from_ntfs_volume() removed as
901 * wimlib_add_image() suffices now.
903 Previously, the soname of libwim.so has been 0.0.0, despite many
904 interface changes. The soname is now updated to 1.0.0 and will now be
905 updated each release.
908 Resources will now be compressed using multiple threads by default.
909 (This applies to `imagex capture', `imagex append', and `imagex
912 Some performance improvements in mounted WIMs.
914 More progress information is shown when capturing a WIM.
917 Lots of minor fixes, code cleanups, and some documentation updates.
918 Nothing in particular is really noteworthy.
921 LZX and XPRESS compression improvements.
923 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
924 Link Bytes of the WIM.
927 Fixed bug when capturing NTFS file with multiple named data streams.
929 Internally, we are now using inode structures, even though these don't
930 appear literally in the WIM file. This simplifies some of the code
931 (mainly for WIM mounting) and likely fixed a few problems, although it
935 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
939 Enough changes to call it version 1.0.0!
941 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
942 to a NTFS volume, is now supported.
944 Hard links and symbolic links have much improved support. They are
945 supported for WIM capture, WIM application, and mounted WIMs (you can
946 even make them on read-write mounted WIMs).
948 Alternate data streams are now supported on mounted WIMs through an
949 xattr or a Windows-style stream interface. Also they are supported when
950 capturing a WIM from NTFS or applying a WIM to NTFS.
952 Split WIMs are better supported. You may now apply an image directly
953 from a split WIM, mount an image from a split WIM read-only, or export
954 an image from a split WIM.
956 Using a capture configuration file is now supported (but not fully yet).
958 SHA1 message digests are checked in more places, so we can make sure
959 applied and captured data is correct.
961 Man pages have been updated and consolidated.
964 Fixed segfault when unmounting read-only WIM.
967 Support for joining and splitting WIMs.
968 Also, security data is now preserved by default.
971 Can now build with older gcc and system headers, like on CentOS 5.
974 Fixed bug that made it impossible to overwrite files in read-write
978 Write byte-order mark before WIM XML data. (imagex.exe requires this to
