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 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
11 'wiminfo'. This option lets you assign values to elements in a WIM
12 file's XML document by name.
14 The wimlib_get_image_property() and wimlib_set_image_property() API
15 functions now support numerically indexed elements.
17 Fixed a bug where, on Windows, wimlib would change the security
18 descriptor of the target directory of an extraction even when the
19 '--no-acls' option was specified.
22 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
23 some Microsoft software would not correctly recognize data in the
26 Made some small improvements to the compression algorithms:
27 LZX compression ratio was slightly improved.
28 XPRESS compression ratio and speed was slightly improved.
29 LZMS compression speed was slightly improved.
31 Improved handling of WIM XML data. wimlib no longer drops unrecognized
32 elements when exporting images. In addition, two API functions were
33 added for better access to elements in the XML document:
34 wimlib_get_image_property() and wimlib_set_image_property().
36 Added support for (unsafe) in-place compaction of WIM files.
38 Improved performance of image export by reusing metadata resources
39 instead of always rebuilding and recompressing them.
41 Improved performance of wimlib_update_image() by delaying the update to
42 the WIM's XML document until a write is requested.
44 On Windows, the target of an extraction may now be a reparse point
45 (which will be dereferenced).
47 On Windows, wimlib now correctly restores non-Microsoft reparse points.
48 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
50 On Windows, wimlib now has improved performance when archiving files
51 from a filesystem backed by a WIM (a "WIMBoot" setup).
53 Several improvements to System Compression (compact mode) support:
55 wof.sys (or wofadk.sys) is now automatically attached to the
56 target volume if needed.
58 Compact-mode extractions now work correctly with wofadk.sys on
59 older versions of Windows.
61 For compatibility with the Windows bootloader, the requested
62 compression format now is overridden on certain files.
67 This release primarily contains various minor bug fixes and
68 improvements, including:
70 Improved handling of deep directory structures.
72 Fixed a bug where on 32-bit systems, the library could enter an
73 infinite loop if a WIM file was malformed in a specific way.
75 Added a workaround for a case where libntfs-3g may report
76 duplicate streams in an NTFS file.
78 Windows symbolic links and junctions in mounted WIM images are
79 now automatically rewritten to be valid in the mounted location.
81 Reparse point fixes: correctly handle the "ReparseReserved"
82 field, and correctly handle "empty" (data-less) reparse points.
84 On Windows, wimlib now acquires SeManageVolumePrivilege, which
85 is needed to create externally backed files using the
88 Improved validation of filenames.
90 Improved LZMS decompression speed.
92 The configure script now honors alternate pkg-config settings.
94 Links have been updated to point to the new website.
96 In addition, experimental support has been added for compressing
97 extracted files using System Compression on Windows 10. This
98 functionality is available through the new '--compact' option to
99 'wimapply' and 'wimextract' as well as new library flags.
102 Fixed a bug in the LZX decompressor: malicious input data could cause
103 out of bounds writes to memory (since wimlib v1.2.2).
105 The output of the 'wiminfo' command now consolidates various boolean
106 flags (such as "Relative path junction") into a single line.
108 A file can now have both an unnamed data stream ("file contents") and a
109 reparse point stream. Such files can exist as a result of the use of
110 certain Windows features, such as offline storage, including "OneDrive".
111 wimlib will now store and restore both streams on Windows as well as in
112 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
114 On Windows, named data streams of encrypted files are no longer stored
115 twice in WIM archives.
117 On Windows, named data streams are now correctly extracted to existing
118 "readonly" directories. Before, an error would be reported.
120 On Windows, it is now possible to do a "WIMBoot mode" extraction with
121 non-standalone WIMs such as delta WIMs.
123 On Windows, when doing an extraction in "WIMBoot mode", files larger
124 than 4 gigabytes are now never extracted as externally backed. This
125 works around a bug in Microsoft's "WOF" driver.
127 The '--enable-verify-compression' configure option has been removed. If
128 you want to verify a WIM file, use the 'wimverify' program.
130 The way the "file count", "directory count", "total bytes", and "hard
131 link bytes" image statistics (stored in the WIM XML data) is calculated
132 has been slightly changed.
134 In mounted WIM images, the disk usage provided for each file (st_blocks)
135 is now the compressed size rather than the uncompressed size.
137 The performance of the NTFS-3g and Windows capture modes has been
140 On UNIX-like systems, symbolic links whose targets contain the backslash
141 character are now handled correctly (losslessly).
144 Improved the LZX compressor. It is now 15-20% faster than before and
145 provides a slightly better compression ratio.
147 Improved the LZMS compressor. It now provides a compression ratio
148 slightly better than WIMGAPI while still being faster and using slightly
151 The compression chunk size in solid resources, e.g. when capturing or
152 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
153 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
154 better compression ratio and is the same value that WIMGAPI uses. The
155 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
156 lower than WIMGAPI's memory usage, but if it is too much, it is still
157 possible to choose a lower value, e.g. with the '--solid-chunk-size'
158 option to wimlib-imagex.
160 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
161 accept the 'K', 'M', and 'G' suffixes.
163 Files are now sorted by name extension when creating a solid WIM file.
165 Fixed various issues related to capture/apply of EFS-encrypted files on
168 The file list printed by 'wimdir' is now sorted by the platform-specific
169 case sensitivity setting, rather than always case sensitively. This
170 also affects the library function wimlib_iterate_dir_tree().
172 On Windows, some error and warning messages have been improved.
175 The Windows binary distribution no longer contains third party DLLs.
176 These dependencies are instead compiled directly into the libwim DLL.
178 Added more fixes for wimlib on non-x86 architectures such as ARM.
180 Extracting files to a Windows PE in-memory filesystem no longer fails if
181 the target files do not yet exist.
183 Improved the performance of XPRESS compression and LZMS decompression.
185 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
186 It will automatically be faster on newer Intel and AMD processors.
188 Removed the --with-imagex-progname and --enable-more-assertions
192 Fix for very slow export from solid WIM / ESD files.
194 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
196 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
197 may use this to treat some types of errors as non-fatal.
199 The library now permits making in-memory changes to a WIMStruct backed
200 by a read-only WIM file.
202 Fixes for "WIMBoot" extraction mode (Windows only):
204 When not using the WOF driver, extraction no longer fails if the
205 disk containing the WIM file has too many partitions.
207 When matching patterns in [PrepopulateList], all hard links of
208 each file are now considered.
210 The system registry files are now automatically treated as being
211 in [PrepopulateList].
213 Added a hack to try to work around an intermittent bug in
214 Microsoft's WOF (Windows Overlay Filesystem) driver.
217 Made more improvements to the XPRESS, LZX, and LZMS compressors.
219 A number of improvements to the Windows port:
221 Fixes for setting short filenames.
223 Faster "WIMBoot" extraction.
225 Updated and slimmed down the dependent DLLs.
227 ACL inheritence bits are now restored.
229 Mandatory integrity labels are now backed up and restored.
231 Added a workaround for an issue where in rare cases, wimlib could create
232 a compressed data stream that could not be read correctly by Windows
233 after an extraction in "WIMBoot" mode.
236 Added file count progress data for
237 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
238 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
240 Added support for testing file exclusions via the user-provided
243 Some documentation improvements.
245 Made some clarifications to the license text in the COPYING file.
248 Made more improvements to the XPRESS, LZX, and LZMS compressors.
250 The default compression mode for wimcapture is now LZX compression in
251 its default mode, which is the same as '--compress=maximum'.
253 You can now specify an optional integer compression level to the
254 '--compress' option; e.g. '--compress=lzx:75'.
256 Made a minor change to the LZMS compressor and decompressor to fix an
257 incompatibility with the Microsoft implementation. In the unlikely
258 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
259 earlier and a checksum error is reported when extracting files from it
260 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
263 Added 'verify' subcommand to wimlib-imagex.
265 Notable library changes:
267 Custom compressor parameters have been removed from the library
268 in favor of the simpler level-based API.
270 Decompressor parameters have been removed entirely.
272 Library users can now specify a custom file for warning and
273 error messages to be sent to, rather than the default of
276 New progress messages:
277 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
278 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
280 New function: wimlib_verify_wim().
283 Improved compression, decompression, and extraction performance.
285 Improved compatibility with version 3584 WIM / ESD files:
286 - Add support for reading and writing multiple solid blocks per
287 archive, which WIMGAPI/DISM can create when appending an image.
288 - Correctly create solid blocks larger than 4 GiB.
290 'add' commands passed to wimupdate will now replace existing
291 nondirectory files by default. Use the --no-replace option to get the
294 The license for the library now contains an exception that allows using
295 it under the LGPL. See the COPYING file for details.
297 In reparse-point fixup mode (the default for capture), symbolic links
298 and junctions that point outside the tree being captured are no longer
299 excluded from capture.
301 Added support for "WIMBoot" capture and extraction. See the
302 documentation for the new '--wimboot' option to wimcapture and wimapply
303 for more information.
305 On UNIX-like systems, you can now backup and restore device nodes, named
306 pipes, and sockets. In addition, 32-bit user and group IDs are now
309 The way that UNIX data is stored in WIM files has been changed. If you
310 captured any WIMs with the --unix-data option, to upgrade them you'll
311 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
312 re-capture them with --unix-data using this version.
314 wimlib now understands tagged metadata items, such as object IDs, that
315 can be stored in WIM directory entries.
317 Removed the --hardlink and --symlink options to wimapply, since I don't
318 think they are too useful and they got in the way of improving the code.
320 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
322 The 'mkwinpeimg' script now supports writing the ISO image to standard
325 The <ARCH> element in WIM XML data is now exported correctly.
327 On Windows, sparse file attributes are no longer set on extracted files.
328 Oddly enough, this actually saves disk space in some cases.
330 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
331 supported. Mounting WIM images now always requires extended attribute
332 support. Use --without-fuse to disable support for mounting WIM images;
333 this will also disable the need for extended attribute support.
335 Configuring with --enable-ssse3-sha1 now works correctly.
337 The shared library version has been bumped up. The main
338 incompatibilities are:
340 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
341 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
344 - User-provided progress functions are now registered using a
345 separate function, wimlib_register_progress_function(). The
346 'progress_func' argument to many functions no longer exists.
348 - The return value from user-provided progress functions is now
351 - A context argument has been added to the prototype of
352 user-provided progress functions.
354 - 'struct wimlib_capture_config' has been removed. The library
355 now takes the path to the configuration file directly. This
356 affects wimlib_add_image(), wimlib_add_image_multisource(),
357 and wimlib_update_image(). However, a NULL value passed in
358 the argument retains the same meaning.
360 - Removed deprecated functions: some (de)compression functions,
361 wimlib_extract_files(), and wimlib_print_metadata().
363 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
364 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
365 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
367 - Removed some progress messages:
368 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
369 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
370 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
373 - Removed some error codes. Numbering stays the same.
375 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
376 WIMLIB_UNMOUNT_FLAG_FORCE.
378 - WIM paths passed to progress functions now have a leading
382 Case-insensitive comparisons of strings (e.g. filenames) containing
383 UTF-16 codepoints above 32767 are now done correctly.
385 Fixed build failure on Mac OS X.
387 wimunmount now provides the '--new-image' option to cause changes to a
388 read-write mounted image to be committed as a new image rather than as
389 an update of the mounted image. (The corresponding new library flag is
390 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
392 The LZMS ("recovery") compression chunk size, or "dictionary size", may
393 now be up to 1 GiB (1,073,741,824 bytes).
395 The performance of LZX ("maximum") and LZMS ("recovery") compression
396 with large chunk sizes has been slightly improved.
399 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
400 decompressed correctly.
402 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
403 occurred in an unlikely case, and due to validity checks it did not
404 affect successfully created archives.
406 Fixed a minor compatibility issue with the LZMS compressor and
407 decompressor. This is *not* the default compression type and was only
408 introduced in v1.6.0. In the unlikely event that you created an
409 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
410 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
413 Memory usage for LZMS and LZX compression has been decreased.
415 wimextract now allows wildcard characters in paths specified on the
416 command line. Also, the '--strict-wildcards' option has been removed
417 and replaced with the inverse option '--nullglob'. See the
418 documentation for wimextract for more details and changes.
420 The wimlib_extract_files() function is now considered deprecated in
421 favor of wimlib_extract_paths().
423 Fixed more permissions problems when extracting files on Windows.
425 A new '--no-attributes' option has been added to wimapply and
426 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
428 The default chunk size is now set correctly when changing the
429 compression type of a WIM, for example with 'wimoptimize'.
431 The '--metadata' option to wiminfo has been replaced with the
432 '--detailed' option to wimdir.
434 In relevant wimlib-imagex commands, '--solid' may now be used as an
435 alias for '--pack-streams'.
438 Support for extracting and updating the new version 3584 WIMs has been
439 added. These WIMs typically pack many streams ("files") together into a
440 single compressed resource, thereby saving space. This degrades the
441 performance of random access (such as that which occurs on a mounted
442 image), but optimizations have been implemented for extraction. These
443 new WIM files also typically use a new compression format (LZMS), which
444 is similar to LZMA and can offer a better compression ratio than LZX.
445 These new WIM files can be created using `wimcapture' with
446 the '--compress=lzms --pack-streams' options. Note: this new WIM format
447 is used by the Windows 8 web downloader, but important segments of the
448 raw '.esd' files are encrypted, so wimlib will not be able to extract
449 such files until they are first decrypted.
451 wimlib now supports extracting files and directories from a WIM image
452 based on a "listfile" that itself contains the list of paths to extract.
453 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
454 and for the library itself, the new APIs are wimlib_extract_pathlist()
455 and wimlib_extract_paths(). Path globs containing wildcard characters
458 For searching WIM files, wimlib now has configurable case sensitivity.
459 The default on Windows is still case-insensitive and the default on
460 UNIX-like systems is still case-sensitive, but this can be overridden
461 on either platform through flags to wimlib_global_init(). For
462 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
463 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
466 Support for compression chunk sizes greater than the default of 32768
467 bytes has been added. A larger chunk size typically results in a better
468 compression ratio. However, the MS implementation is seemingly not
469 compatible with all chunk sizes, especially for LZX compression, so the
470 defaults remain unchanged, with the exception of the new LZMS-compressed
471 WIMs, which use a larger chunk size by default.
473 The compression/decompression API exported by wimlib has been changed.
474 Now one set of functions handles all supported compression formats.
476 `wimcapture' and `wimappend' will now display the progress of scanning
477 the directory tree to capture, in addition to the progress of writing
478 data to the WIM. The '--verbose' option no longer does anything. The
479 library API change for this is the addition of several members to
480 `struct wimlib_progress_info_scan' available to progress callbacks.
482 `mkwinpeimg' now correctly handles the '--start-script' option when the
483 start script is not in the working directory.
485 Sequential extraction, previously requested by using
486 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
487 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
488 behavior (extract in file order).
491 The new LZX compressor added in v1.5.2 has been improved and is now
492 enabled by default, except when `wimcapture' or `wimappend' is run
493 *without* the '--compress' option, in which case the faster LZX
494 compressor is used (the same as before). This behavior is reasonably
495 consistent with ImageX which actually uses "fast" (XPRESS) compression
496 by default. In those cases, use '--compress=maximum' to explicitly
497 capture a WIM image using the new (slower but better) LZX compressor.
499 The '--compress-slow' option still exists to `wimlib-imagex optimize',
500 but its new behavior is to tweak the new LZX compressor even more to
501 produce an even better compression ratio at the cost of more time spent
504 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
505 which recompresses the WIM file using the specified compression TYPE.
506 The new library API function used for this is
507 wimlib_set_output_compression_type().
509 Added the wimlib_get_xml_data() function to allow library clients to
510 easily retrieve the raw XML data from a WIM file if needed.
512 Fixed a bug that could cause an error code to be incorrectly returned
513 when writing XML data containing a <WINDOWS> element.
515 Mounted WIM images will now correctly show the default file stream even
516 if appears in the alternate data stream entries of the corresponding WIM
520 Added a new experimental LZX compressor which can be enabled by passing
521 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
522 optimize'. (The latter is only applicable if the WIM is already
523 LZX-compressed and the '--recompress' option is also given.) The
524 experimental compressor is much slower but compresses the data slightly
525 more --- currently usually to within a fraction of a percent of the
526 results from WIMGAPI/ImageX.
528 A workaround has been added for compatibility with versions of WinPE
529 that interpret alternate data stream entries in the boot WIM
532 An alignment bug that caused a crash in the LZX decompressor on some
535 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
536 the WIM header when restoring the previous state of a WIM it failed to
539 Added a workaround to avoid an access denied error on Windows when
540 replacing a WIM file that another process has opened.
543 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
544 needed to be handled.
546 A bug in the interpretation of negative IMAGE indices in the
547 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
548 `wimlib-imagex append' has been fixed.
550 A workaround has been added to successfully apply security descriptors
551 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
552 2013.1.13 or earlier.
554 `wimlib-imagex capture' can now accept the '--delta-from' option
558 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
559 to standard output and applying images from standard input, but they are
560 not compatible with Microsoft's software and are not created by default.
561 See the documentation for --pipable flag of `wimlib-imagex capture' for
564 To better support incremental backups, added support for declaring an
565 image as a modified form of another image. See the documentation for
566 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
569 Added supported for "delta" WIMs. See the documentation for the
570 '--delta-from' option of `wimlib-imagex capture'.
572 The library support for managing split WIMs has been changed to support
573 other arrangements, such as delta WIMs, and be easier to use. This
574 change is visible in `wimlib-imagex', which also can now accept the
575 '--ref' option multiple times, and also now supports "delta" WIMs as
578 wimlib now preserves WIM integrity tables by default, even if
579 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
580 behavior of `wimlib-imagex' whenever the WIM being operated on contains
581 an integrity table and the '--check' option is not specified.
583 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
584 (when --compress is not specified). This provides the best compression
585 ratio by default, which is usually what is desired, at a cost of some
588 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
589 is the command as in `wimlib-imagex COMMAND'; for example, it can be
590 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
591 appropriate hard links are created in UNIX installations of
592 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
593 batch files that emulate this behavior are generated.
595 Security descriptors are now extracted correctly on Windows.
597 Fixed archiving DOS names in NTFS-3g capture mode.
599 The extraction code has been rewritten and it will now be easier to
600 support new features on all supported backends (currently Win32, UNIX,
601 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
602 now supported on all backends, not just UNIX.
604 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
605 than the WAIK itself.
607 wimlib_global_init() now, by default, attempts to acquire additional
608 privileges on Windows, so library clients need not do this.
610 This update bumps the shared library version number up to 9, since it is
611 not binary compatibible with previous releases.
614 Fixed bug in `wimlib-imagex export' that made it impossible to export an
615 image from a WIM that is readonly at the filesystem level.
617 Return error code rather than segfaulting when trying to list files from
618 a non-first part of a split WIM.
620 Joining a WIM will now preserve the RP_FIX and READONLY flags.
623 On Windows, paths given to wimlib-imagex are now treated case
626 Improved behavior regarding invalid filenames; in particular, on
627 Windows, wimlib-imagex will, when extracting, now omit (with an option
628 to override this default) filenames differing only in case, or filenames
629 containing characters not valid on Windows.
631 On Windows, wimlib now supports capturing and extracting long paths
632 (longer than the so-called MAX_PATH).
634 On Windows, `wimlib-imagex update' now acquires proper privileges when
635 running as an Administrator.
637 `wimlib-imagex update' will now complain if no image is specified when
638 trying to update a multi-image WIM.
640 `wimlib-imagex update' now supports specifying a single update command
641 directly on the command line using the --command option.
643 wimlib-imagex will now choose different units for progress messages,
644 depending on the amount of data that needs to be processed.
646 `wimlib-imagex append' will now generate a unique WIM image name if no
647 name is specified and the defaulted name already exists in the WIM.
649 wimlib now allows you to create unnamed WIM images, which can then only
650 be referred to by index.
652 wimlib now allows you to explicitly declare you want write access to a
653 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
656 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
659 Progress callbacks have been added to wimlib's wimlib_update_image()
662 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
663 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
666 NTFS-3g capture now only warns about two conditions previously treated
669 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
672 wimlib now correctly detects and returns an error when reading a WIM
673 image with a cyclic directory structure. (Fun fact: such a WIM will
674 crash Microsoft's software.)
677 Added new "extract" and "update" subcommands to wimlib-imagex, along
678 with associated APIs in the library. These commands are intended mainly
679 for Windows use but can be used on UNIX as well.
681 Many documentation improvements.
683 Fixed a bug in the Windows build where relative symbolic links were not
684 captured in reparse-point fixup mode.
686 Fixed a bug in the Windows build where file handles were left open to
687 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
689 Fixed a bug in the Windows build of wimlib-imagex where globbing
690 split-WIM parts could cause the program to crash.
692 Fixed a bug where the creation time of WIM images would be shown instead
693 of the last modification time.
695 With the Windows build it is now possible to restore a WIM containing
696 symbolic links as a non-Administrator; however you will receive warnings
697 about not being able to extract the symbolic links.
700 Capturing a WIM image should now be significantly faster in most cases
701 due to improved use of the operating system's cache and avoiding reading
702 files twice whenever possible.
704 The Windows build should now work on Windows XP.
706 The Windows build now supports capturing and restoring hidden,
707 compressed, sparse, and encrypted files.
709 The Windows build now supports capturing and applying WIM images from
710 filesystems other than NTFS (with some reduced functionality).
712 The Windows build now extracts short names correctly.
714 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
715 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
716 capture' and `wimlib-imagex apply'.
718 The performance of splitting and joining WIMs should be slightly
721 The LZX and XPRESS compression and decompression functions are now
722 exported from the library.
725 Improvements and bugfixes for the Windows build.
727 Added --strict-acls options.
729 Fixed the way that wimlib determines the order of images in the WIM.
732 Since wimlib can now be used on Windows, wimlib's implementation of
733 ImageX has been renamed to wimlib-imagex to avoid confusion with
734 Microsoft's implementation of ImageX, which would have the same file
735 name ("imagex.exe"). If you really don't like this you can pass the
736 --with-imagex-progname option to `configure' to choose a different name,
737 or even simply rename the binary yourself (but the former way will
738 configure the man pages to use the chosen name).
740 Various bugs fixed in the Windows build. Mainly to do with capturing
741 and restoring alternate data streams correctly in weird cases, and
742 requesting the correct privileges when opening files. Also added the
743 --noacls options to wimlib-imagex capture, append, and apply.
745 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
746 dynamically loaded, so this may make the library compatible with Windows
747 XP (however, there may still be other problems).
750 Added experimental support for native Windows builds. Binaries can be
751 downloaded from the SourceForge page.
753 --source-list option added to `imagex capture' and `imagex append'.
755 Better support for different character encodings.
758 Storing UNIX file owners, groups, and modes in WIM images is now
759 possible using `imagex capture' with the --unix-data flag.
761 Minor bug fixes and documentation fixes.
764 NTFS capture: Fixed capturing duplicate reparse points.
766 NTFS capture: Capture first unnamed stream if there are more than one
767 (print warning instead of error).
769 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
772 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
775 Update to work with ntfs-3g version 2013.1.13.
778 Fixed truncating file to shorter but non-zero length on read-write
781 Various code cleanups and minor documentation fixes.
784 LZX and XPRESS decompression have received some additional optimizations
785 and should now be even faster. (Although, they were already pretty
786 fast--- much faster than typical I/O speeds.)
788 Fixed a bug introduced in v1.2.1 that would cause a directory tree
789 containing hard links to be captured incorrectly in some cases.
792 By default, unmounting a read-write mounted WIM with 'imagex unmount
793 --commit' will now change the WIM in-place without needing to write the
794 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
797 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
798 for a response from the daemon servicing the mounted WIM. Instead,
799 every second 'imagex unmount' will check if the daemon is still alive,
800 and keep waiting if so, otherwise terminate with an error.
802 'imagex unmount --commit' on a read-write mounted WIM will now print
803 progress information regarding the writing of new or modified streams
804 the WIM, just like when capturing or appending a WIM.
806 A small change has been made to XPRESS compression and it should improve
807 the compression ratio slightly.
809 A change was made that may improve performance slightly when applying a
810 WIM image to a NTFS volume.
812 Microsoft has managed to introduce even more bugs into their software,
813 and now the WIMs for Windows 8 have incorrect (too low) reference counts
814 for some streams. This is unsafe because such streams can be removed
815 when they are in actuality still referenced in the WIM (perhaps by a
816 different image). wimlib will now work around this problem by fixing
817 the stream reference counts. This is only done when wimlib_delete_image() is
818 called ('imagex delete') or when wimlib_mount_image() is called with
819 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
820 requires reading the metadata for all images in the WIM, so this will
821 make these operations noticably slower on WIMs with multiple images.
823 Various other bugfixes.
826 Appending images to a WIM is now be done by default without re-building
827 the whole WIM. Use the --rebuild flag to get the old behavior (which
828 was to re-build the entire WIM when a new image is appended).
830 A new command `imagex optimize' is now available to manually re-build a
831 WIM that has wasted space due to repeated appends.
833 Progress information has been improved, and now arbitrary callback
834 functions can be used to show the progress of a WIM operation.
836 A possible bug with changing the bootable image of a WIM was fixed.
838 Some advisory locking is now done to prevent two processes from
839 modifying a WIM at the same time (but only in some cases). For example,
840 you cannot mount two images from a WIM read-write at the same time.
842 Some functions have been reorganized:
843 * wimlib_mount() renamed to wimlib_mount_image().
844 * wimlib_unmount() renamed to wimlib_unmount_image().
845 * wimlib_overwrite_xml_and_header() removed as
846 wimlib_overwrite() suffices now.
847 * wimlib_apply_image_to_ntfs_volume() removed as
848 wimlib_extract_image() suffices now.
849 * wimlib_add_image_from_ntfs_volume() removed as
850 * wimlib_add_image() suffices now.
852 Previously, the soname of libwim.so has been 0.0.0, despite many
853 interface changes. The soname is now updated to 1.0.0 and will now be
854 updated each release.
857 Resources will now be compressed using multiple threads by default.
858 (This applies to `imagex capture', `imagex append', and `imagex
861 Some performance improvements in mounted WIMs.
863 More progress information is shown when capturing a WIM.
866 Lots of minor fixes, code cleanups, and some documentation updates.
867 Nothing in particular is really noteworthy.
870 LZX and XPRESS compression improvements.
872 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
873 Link Bytes of the WIM.
876 Fixed bug when capturing NTFS file with multiple named data streams.
878 Internally, we are now using inode structures, even though these don't
879 appear literally in the WIM file. This simplifies some of the code
880 (mainly for WIM mounting) and likely fixed a few problems, although it
884 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
888 Enough changes to call it version 1.0.0!
890 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
891 to a NTFS volume, is now supported.
893 Hard links and symbolic links have much improved support. They are
894 supported for WIM capture, WIM application, and mounted WIMs (you can
895 even make them on read-write mounted WIMs).
897 Alternate data streams are now supported on mounted WIMs through an
898 xattr or a Windows-style stream interface. Also they are supported when
899 capturing a WIM from NTFS or applying a WIM to NTFS.
901 Split WIMs are better supported. You may now apply an image directly
902 from a split WIM, mount an image from a split WIM read-only, or export
903 an image from a split WIM.
905 Using a capture configuration file is now supported (but not fully yet).
907 SHA1 message digests are checked in more places, so we can make sure
908 applied and captured data is correct.
910 Man pages have been updated and consolidated.
913 Fixed segfault when unmounting read-only WIM.
916 Support for joining and splitting WIMs.
917 Also, security data is now preserved by default.
920 Can now build with older gcc and system headers, like on CentOS 5.
923 Fixed bug that made it impossible to overwrite files in read-write
927 Write byte-order mark before WIM XML data. (imagex.exe requires this to
