2 Added experimental support for Windows VSS (Volume Shadow Copy Service).
3 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
4 create and use a temporary VSS snapshot when capturing a WIM image.
6 Implemented setting of Windows-specific XML information, such as
7 architecture, system root, and version details. This information is now
8 automatically set in newly captured WIM images, when appropriate.
10 Significantly improved performance of directory scans of full NTFS
11 volumes on Windows 8 and later.
13 The progress messages printed by wimlib-imagex while writing WIM files
14 have been slightly tweaked.
16 Progress information for directory tree scans now counts all hard links.
18 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
19 'wiminfo'. This option lets you assign values to elements in a WIM
20 file's XML document by name.
22 The wimlib_get_image_property() and wimlib_set_image_property() API
23 functions now support numerically indexed elements.
25 Fixed a bug where, on Windows, wimlib would change the security
26 descriptor of the target directory of an extraction even when the
27 '--no-acls' option was specified.
30 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
31 some Microsoft software would not correctly recognize data in the
34 Made some small improvements to the compression algorithms:
35 LZX compression ratio was slightly improved.
36 XPRESS compression ratio and speed was slightly improved.
37 LZMS compression speed was slightly improved.
39 Improved handling of WIM XML data. wimlib no longer drops unrecognized
40 elements when exporting images. In addition, two API functions were
41 added for better access to elements in the XML document:
42 wimlib_get_image_property() and wimlib_set_image_property().
44 Added support for (unsafe) in-place compaction of WIM files.
46 Improved performance of image export by reusing metadata resources
47 instead of always rebuilding and recompressing them.
49 Improved performance of wimlib_update_image() by delaying the update to
50 the WIM's XML document until a write is requested.
52 On Windows, the target of an extraction may now be a reparse point
53 (which will be dereferenced).
55 On Windows, wimlib now correctly restores non-Microsoft reparse points.
56 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
58 On Windows, wimlib now has improved performance when archiving files
59 from a filesystem backed by a WIM (a "WIMBoot" setup).
61 Several improvements to System Compression (compact mode) support:
63 wof.sys (or wofadk.sys) is now automatically attached to the
64 target volume if needed.
66 Compact-mode extractions now work correctly with wofadk.sys on
67 older versions of Windows.
69 For compatibility with the Windows bootloader, the requested
70 compression format now is overridden on certain files.
75 This release primarily contains various minor bug fixes and
76 improvements, including:
78 Improved handling of deep directory structures.
80 Fixed a bug where on 32-bit systems, the library could enter an
81 infinite loop if a WIM file was malformed in a specific way.
83 Added a workaround for a case where libntfs-3g may report
84 duplicate streams in an NTFS file.
86 Windows symbolic links and junctions in mounted WIM images are
87 now automatically rewritten to be valid in the mounted location.
89 Reparse point fixes: correctly handle the "ReparseReserved"
90 field, and correctly handle "empty" (data-less) reparse points.
92 On Windows, wimlib now acquires SeManageVolumePrivilege, which
93 is needed to create externally backed files using the
96 Improved validation of filenames.
98 Improved LZMS decompression speed.
100 The configure script now honors alternate pkg-config settings.
102 Links have been updated to point to the new website.
104 In addition, experimental support has been added for compressing
105 extracted files using System Compression on Windows 10. This
106 functionality is available through the new '--compact' option to
107 'wimapply' and 'wimextract' as well as new library flags.
110 Fixed a bug in the LZX decompressor: malicious input data could cause
111 out of bounds writes to memory (since wimlib v1.2.2).
113 The output of the 'wiminfo' command now consolidates various boolean
114 flags (such as "Relative path junction") into a single line.
116 A file can now have both an unnamed data stream ("file contents") and a
117 reparse point stream. Such files can exist as a result of the use of
118 certain Windows features, such as offline storage, including "OneDrive".
119 wimlib will now store and restore both streams on Windows as well as in
120 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
122 On Windows, named data streams of encrypted files are no longer stored
123 twice in WIM archives.
125 On Windows, named data streams are now correctly extracted to existing
126 "readonly" directories. Before, an error would be reported.
128 On Windows, it is now possible to do a "WIMBoot mode" extraction with
129 non-standalone WIMs such as delta WIMs.
131 On Windows, when doing an extraction in "WIMBoot mode", files larger
132 than 4 gigabytes are now never extracted as externally backed. This
133 works around a bug in Microsoft's "WOF" driver.
135 The '--enable-verify-compression' configure option has been removed. If
136 you want to verify a WIM file, use the 'wimverify' program.
138 The way the "file count", "directory count", "total bytes", and "hard
139 link bytes" image statistics (stored in the WIM XML data) is calculated
140 has been slightly changed.
142 In mounted WIM images, the disk usage provided for each file (st_blocks)
143 is now the compressed size rather than the uncompressed size.
145 The performance of the NTFS-3g and Windows capture modes has been
148 On UNIX-like systems, symbolic links whose targets contain the backslash
149 character are now handled correctly (losslessly).
152 Improved the LZX compressor. It is now 15-20% faster than before and
153 provides a slightly better compression ratio.
155 Improved the LZMS compressor. It now provides a compression ratio
156 slightly better than WIMGAPI while still being faster and using slightly
159 The compression chunk size in solid resources, e.g. when capturing or
160 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
161 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
162 better compression ratio and is the same value that WIMGAPI uses. The
163 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
164 lower than WIMGAPI's memory usage, but if it is too much, it is still
165 possible to choose a lower value, e.g. with the '--solid-chunk-size'
166 option to wimlib-imagex.
168 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
169 accept the 'K', 'M', and 'G' suffixes.
171 Files are now sorted by name extension when creating a solid WIM file.
173 Fixed various issues related to capture/apply of EFS-encrypted files on
176 The file list printed by 'wimdir' is now sorted by the platform-specific
177 case sensitivity setting, rather than always case sensitively. This
178 also affects the library function wimlib_iterate_dir_tree().
180 On Windows, some error and warning messages have been improved.
183 The Windows binary distribution no longer contains third party DLLs.
184 These dependencies are instead compiled directly into the libwim DLL.
186 Added more fixes for wimlib on non-x86 architectures such as ARM.
188 Extracting files to a Windows PE in-memory filesystem no longer fails if
189 the target files do not yet exist.
191 Improved the performance of XPRESS compression and LZMS decompression.
193 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
194 It will automatically be faster on newer Intel and AMD processors.
196 Removed the --with-imagex-progname and --enable-more-assertions
200 Fix for very slow export from solid WIM / ESD files.
202 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
204 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
205 may use this to treat some types of errors as non-fatal.
207 The library now permits making in-memory changes to a WIMStruct backed
208 by a read-only WIM file.
210 Fixes for "WIMBoot" extraction mode (Windows only):
212 When not using the WOF driver, extraction no longer fails if the
213 disk containing the WIM file has too many partitions.
215 When matching patterns in [PrepopulateList], all hard links of
216 each file are now considered.
218 The system registry files are now automatically treated as being
219 in [PrepopulateList].
221 Added a hack to try to work around an intermittent bug in
222 Microsoft's WOF (Windows Overlay Filesystem) driver.
225 Made more improvements to the XPRESS, LZX, and LZMS compressors.
227 A number of improvements to the Windows port:
229 Fixes for setting short filenames.
231 Faster "WIMBoot" extraction.
233 Updated and slimmed down the dependent DLLs.
235 ACL inheritence bits are now restored.
237 Mandatory integrity labels are now backed up and restored.
239 Added a workaround for an issue where in rare cases, wimlib could create
240 a compressed data stream that could not be read correctly by Windows
241 after an extraction in "WIMBoot" mode.
244 Added file count progress data for
245 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
246 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
248 Added support for testing file exclusions via the user-provided
251 Some documentation improvements.
253 Made some clarifications to the license text in the COPYING file.
256 Made more improvements to the XPRESS, LZX, and LZMS compressors.
258 The default compression mode for wimcapture is now LZX compression in
259 its default mode, which is the same as '--compress=maximum'.
261 You can now specify an optional integer compression level to the
262 '--compress' option; e.g. '--compress=lzx:75'.
264 Made a minor change to the LZMS compressor and decompressor to fix an
265 incompatibility with the Microsoft implementation. In the unlikely
266 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
267 earlier and a checksum error is reported when extracting files from it
268 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
271 Added 'verify' subcommand to wimlib-imagex.
273 Notable library changes:
275 Custom compressor parameters have been removed from the library
276 in favor of the simpler level-based API.
278 Decompressor parameters have been removed entirely.
280 Library users can now specify a custom file for warning and
281 error messages to be sent to, rather than the default of
284 New progress messages:
285 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
286 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
288 New function: wimlib_verify_wim().
291 Improved compression, decompression, and extraction performance.
293 Improved compatibility with version 3584 WIM / ESD files:
294 - Add support for reading and writing multiple solid blocks per
295 archive, which WIMGAPI/DISM can create when appending an image.
296 - Correctly create solid blocks larger than 4 GiB.
298 'add' commands passed to wimupdate will now replace existing
299 nondirectory files by default. Use the --no-replace option to get the
302 The license for the library now contains an exception that allows using
303 it under the LGPL. See the COPYING file for details.
305 In reparse-point fixup mode (the default for capture), symbolic links
306 and junctions that point outside the tree being captured are no longer
307 excluded from capture.
309 Added support for "WIMBoot" capture and extraction. See the
310 documentation for the new '--wimboot' option to wimcapture and wimapply
311 for more information.
313 On UNIX-like systems, you can now backup and restore device nodes, named
314 pipes, and sockets. In addition, 32-bit user and group IDs are now
317 The way that UNIX data is stored in WIM files has been changed. If you
318 captured any WIMs with the --unix-data option, to upgrade them you'll
319 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
320 re-capture them with --unix-data using this version.
322 wimlib now understands tagged metadata items, such as object IDs, that
323 can be stored in WIM directory entries.
325 Removed the --hardlink and --symlink options to wimapply, since I don't
326 think they are too useful and they got in the way of improving the code.
328 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
330 The 'mkwinpeimg' script now supports writing the ISO image to standard
333 The <ARCH> element in WIM XML data is now exported correctly.
335 On Windows, sparse file attributes are no longer set on extracted files.
336 Oddly enough, this actually saves disk space in some cases.
338 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
339 supported. Mounting WIM images now always requires extended attribute
340 support. Use --without-fuse to disable support for mounting WIM images;
341 this will also disable the need for extended attribute support.
343 Configuring with --enable-ssse3-sha1 now works correctly.
345 The shared library version has been bumped up. The main
346 incompatibilities are:
348 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
349 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
352 - User-provided progress functions are now registered using a
353 separate function, wimlib_register_progress_function(). The
354 'progress_func' argument to many functions no longer exists.
356 - The return value from user-provided progress functions is now
359 - A context argument has been added to the prototype of
360 user-provided progress functions.
362 - 'struct wimlib_capture_config' has been removed. The library
363 now takes the path to the configuration file directly. This
364 affects wimlib_add_image(), wimlib_add_image_multisource(),
365 and wimlib_update_image(). However, a NULL value passed in
366 the argument retains the same meaning.
368 - Removed deprecated functions: some (de)compression functions,
369 wimlib_extract_files(), and wimlib_print_metadata().
371 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
372 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
373 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
375 - Removed some progress messages:
376 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
377 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
378 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
381 - Removed some error codes. Numbering stays the same.
383 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
384 WIMLIB_UNMOUNT_FLAG_FORCE.
386 - WIM paths passed to progress functions now have a leading
390 Case-insensitive comparisons of strings (e.g. filenames) containing
391 UTF-16 codepoints above 32767 are now done correctly.
393 Fixed build failure on Mac OS X.
395 wimunmount now provides the '--new-image' option to cause changes to a
396 read-write mounted image to be committed as a new image rather than as
397 an update of the mounted image. (The corresponding new library flag is
398 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
400 The LZMS ("recovery") compression chunk size, or "dictionary size", may
401 now be up to 1 GiB (1,073,741,824 bytes).
403 The performance of LZX ("maximum") and LZMS ("recovery") compression
404 with large chunk sizes has been slightly improved.
407 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
408 decompressed correctly.
410 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
411 occurred in an unlikely case, and due to validity checks it did not
412 affect successfully created archives.
414 Fixed a minor compatibility issue with the LZMS compressor and
415 decompressor. This is *not* the default compression type and was only
416 introduced in v1.6.0. In the unlikely event that you created an
417 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
418 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
421 Memory usage for LZMS and LZX compression has been decreased.
423 wimextract now allows wildcard characters in paths specified on the
424 command line. Also, the '--strict-wildcards' option has been removed
425 and replaced with the inverse option '--nullglob'. See the
426 documentation for wimextract for more details and changes.
428 The wimlib_extract_files() function is now considered deprecated in
429 favor of wimlib_extract_paths().
431 Fixed more permissions problems when extracting files on Windows.
433 A new '--no-attributes' option has been added to wimapply and
434 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
436 The default chunk size is now set correctly when changing the
437 compression type of a WIM, for example with 'wimoptimize'.
439 The '--metadata' option to wiminfo has been replaced with the
440 '--detailed' option to wimdir.
442 In relevant wimlib-imagex commands, '--solid' may now be used as an
443 alias for '--pack-streams'.
446 Support for extracting and updating the new version 3584 WIMs has been
447 added. These WIMs typically pack many streams ("files") together into a
448 single compressed resource, thereby saving space. This degrades the
449 performance of random access (such as that which occurs on a mounted
450 image), but optimizations have been implemented for extraction. These
451 new WIM files also typically use a new compression format (LZMS), which
452 is similar to LZMA and can offer a better compression ratio than LZX.
453 These new WIM files can be created using `wimcapture' with
454 the '--compress=lzms --pack-streams' options. Note: this new WIM format
455 is used by the Windows 8 web downloader, but important segments of the
456 raw '.esd' files are encrypted, so wimlib will not be able to extract
457 such files until they are first decrypted.
459 wimlib now supports extracting files and directories from a WIM image
460 based on a "listfile" that itself contains the list of paths to extract.
461 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
462 and for the library itself, the new APIs are wimlib_extract_pathlist()
463 and wimlib_extract_paths(). Path globs containing wildcard characters
466 For searching WIM files, wimlib now has configurable case sensitivity.
467 The default on Windows is still case-insensitive and the default on
468 UNIX-like systems is still case-sensitive, but this can be overridden
469 on either platform through flags to wimlib_global_init(). For
470 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
471 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
474 Support for compression chunk sizes greater than the default of 32768
475 bytes has been added. A larger chunk size typically results in a better
476 compression ratio. However, the MS implementation is seemingly not
477 compatible with all chunk sizes, especially for LZX compression, so the
478 defaults remain unchanged, with the exception of the new LZMS-compressed
479 WIMs, which use a larger chunk size by default.
481 The compression/decompression API exported by wimlib has been changed.
482 Now one set of functions handles all supported compression formats.
484 `wimcapture' and `wimappend' will now display the progress of scanning
485 the directory tree to capture, in addition to the progress of writing
486 data to the WIM. The '--verbose' option no longer does anything. The
487 library API change for this is the addition of several members to
488 `struct wimlib_progress_info_scan' available to progress callbacks.
490 `mkwinpeimg' now correctly handles the '--start-script' option when the
491 start script is not in the working directory.
493 Sequential extraction, previously requested by using
494 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
495 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
496 behavior (extract in file order).
499 The new LZX compressor added in v1.5.2 has been improved and is now
500 enabled by default, except when `wimcapture' or `wimappend' is run
501 *without* the '--compress' option, in which case the faster LZX
502 compressor is used (the same as before). This behavior is reasonably
503 consistent with ImageX which actually uses "fast" (XPRESS) compression
504 by default. In those cases, use '--compress=maximum' to explicitly
505 capture a WIM image using the new (slower but better) LZX compressor.
507 The '--compress-slow' option still exists to `wimlib-imagex optimize',
508 but its new behavior is to tweak the new LZX compressor even more to
509 produce an even better compression ratio at the cost of more time spent
512 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
513 which recompresses the WIM file using the specified compression TYPE.
514 The new library API function used for this is
515 wimlib_set_output_compression_type().
517 Added the wimlib_get_xml_data() function to allow library clients to
518 easily retrieve the raw XML data from a WIM file if needed.
520 Fixed a bug that could cause an error code to be incorrectly returned
521 when writing XML data containing a <WINDOWS> element.
523 Mounted WIM images will now correctly show the default file stream even
524 if appears in the alternate data stream entries of the corresponding WIM
528 Added a new experimental LZX compressor which can be enabled by passing
529 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
530 optimize'. (The latter is only applicable if the WIM is already
531 LZX-compressed and the '--recompress' option is also given.) The
532 experimental compressor is much slower but compresses the data slightly
533 more --- currently usually to within a fraction of a percent of the
534 results from WIMGAPI/ImageX.
536 A workaround has been added for compatibility with versions of WinPE
537 that interpret alternate data stream entries in the boot WIM
540 An alignment bug that caused a crash in the LZX decompressor on some
543 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
544 the WIM header when restoring the previous state of a WIM it failed to
547 Added a workaround to avoid an access denied error on Windows when
548 replacing a WIM file that another process has opened.
551 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
552 needed to be handled.
554 A bug in the interpretation of negative IMAGE indices in the
555 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
556 `wimlib-imagex append' has been fixed.
558 A workaround has been added to successfully apply security descriptors
559 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
560 2013.1.13 or earlier.
562 `wimlib-imagex capture' can now accept the '--delta-from' option
566 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
567 to standard output and applying images from standard input, but they are
568 not compatible with Microsoft's software and are not created by default.
569 See the documentation for --pipable flag of `wimlib-imagex capture' for
572 To better support incremental backups, added support for declaring an
573 image as a modified form of another image. See the documentation for
574 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
577 Added supported for "delta" WIMs. See the documentation for the
578 '--delta-from' option of `wimlib-imagex capture'.
580 The library support for managing split WIMs has been changed to support
581 other arrangements, such as delta WIMs, and be easier to use. This
582 change is visible in `wimlib-imagex', which also can now accept the
583 '--ref' option multiple times, and also now supports "delta" WIMs as
586 wimlib now preserves WIM integrity tables by default, even if
587 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
588 behavior of `wimlib-imagex' whenever the WIM being operated on contains
589 an integrity table and the '--check' option is not specified.
591 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
592 (when --compress is not specified). This provides the best compression
593 ratio by default, which is usually what is desired, at a cost of some
596 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
597 is the command as in `wimlib-imagex COMMAND'; for example, it can be
598 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
599 appropriate hard links are created in UNIX installations of
600 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
601 batch files that emulate this behavior are generated.
603 Security descriptors are now extracted correctly on Windows.
605 Fixed archiving DOS names in NTFS-3g capture mode.
607 The extraction code has been rewritten and it will now be easier to
608 support new features on all supported backends (currently Win32, UNIX,
609 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
610 now supported on all backends, not just UNIX.
612 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
613 than the WAIK itself.
615 wimlib_global_init() now, by default, attempts to acquire additional
616 privileges on Windows, so library clients need not do this.
618 This update bumps the shared library version number up to 9, since it is
619 not binary compatibible with previous releases.
622 Fixed bug in `wimlib-imagex export' that made it impossible to export an
623 image from a WIM that is readonly at the filesystem level.
625 Return error code rather than segfaulting when trying to list files from
626 a non-first part of a split WIM.
628 Joining a WIM will now preserve the RP_FIX and READONLY flags.
631 On Windows, paths given to wimlib-imagex are now treated case
634 Improved behavior regarding invalid filenames; in particular, on
635 Windows, wimlib-imagex will, when extracting, now omit (with an option
636 to override this default) filenames differing only in case, or filenames
637 containing characters not valid on Windows.
639 On Windows, wimlib now supports capturing and extracting long paths
640 (longer than the so-called MAX_PATH).
642 On Windows, `wimlib-imagex update' now acquires proper privileges when
643 running as an Administrator.
645 `wimlib-imagex update' will now complain if no image is specified when
646 trying to update a multi-image WIM.
648 `wimlib-imagex update' now supports specifying a single update command
649 directly on the command line using the --command option.
651 wimlib-imagex will now choose different units for progress messages,
652 depending on the amount of data that needs to be processed.
654 `wimlib-imagex append' will now generate a unique WIM image name if no
655 name is specified and the defaulted name already exists in the WIM.
657 wimlib now allows you to create unnamed WIM images, which can then only
658 be referred to by index.
660 wimlib now allows you to explicitly declare you want write access to a
661 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
664 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
667 Progress callbacks have been added to wimlib's wimlib_update_image()
670 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
671 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
674 NTFS-3g capture now only warns about two conditions previously treated
677 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
680 wimlib now correctly detects and returns an error when reading a WIM
681 image with a cyclic directory structure. (Fun fact: such a WIM will
682 crash Microsoft's software.)
685 Added new "extract" and "update" subcommands to wimlib-imagex, along
686 with associated APIs in the library. These commands are intended mainly
687 for Windows use but can be used on UNIX as well.
689 Many documentation improvements.
691 Fixed a bug in the Windows build where relative symbolic links were not
692 captured in reparse-point fixup mode.
694 Fixed a bug in the Windows build where file handles were left open to
695 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
697 Fixed a bug in the Windows build of wimlib-imagex where globbing
698 split-WIM parts could cause the program to crash.
700 Fixed a bug where the creation time of WIM images would be shown instead
701 of the last modification time.
703 With the Windows build it is now possible to restore a WIM containing
704 symbolic links as a non-Administrator; however you will receive warnings
705 about not being able to extract the symbolic links.
708 Capturing a WIM image should now be significantly faster in most cases
709 due to improved use of the operating system's cache and avoiding reading
710 files twice whenever possible.
712 The Windows build should now work on Windows XP.
714 The Windows build now supports capturing and restoring hidden,
715 compressed, sparse, and encrypted files.
717 The Windows build now supports capturing and applying WIM images from
718 filesystems other than NTFS (with some reduced functionality).
720 The Windows build now extracts short names correctly.
722 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
723 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
724 capture' and `wimlib-imagex apply'.
726 The performance of splitting and joining WIMs should be slightly
729 The LZX and XPRESS compression and decompression functions are now
730 exported from the library.
733 Improvements and bugfixes for the Windows build.
735 Added --strict-acls options.
737 Fixed the way that wimlib determines the order of images in the WIM.
740 Since wimlib can now be used on Windows, wimlib's implementation of
741 ImageX has been renamed to wimlib-imagex to avoid confusion with
742 Microsoft's implementation of ImageX, which would have the same file
743 name ("imagex.exe"). If you really don't like this you can pass the
744 --with-imagex-progname option to `configure' to choose a different name,
745 or even simply rename the binary yourself (but the former way will
746 configure the man pages to use the chosen name).
748 Various bugs fixed in the Windows build. Mainly to do with capturing
749 and restoring alternate data streams correctly in weird cases, and
750 requesting the correct privileges when opening files. Also added the
751 --noacls options to wimlib-imagex capture, append, and apply.
753 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
754 dynamically loaded, so this may make the library compatible with Windows
755 XP (however, there may still be other problems).
758 Added experimental support for native Windows builds. Binaries can be
759 downloaded from the SourceForge page.
761 --source-list option added to `imagex capture' and `imagex append'.
763 Better support for different character encodings.
766 Storing UNIX file owners, groups, and modes in WIM images is now
767 possible using `imagex capture' with the --unix-data flag.
769 Minor bug fixes and documentation fixes.
772 NTFS capture: Fixed capturing duplicate reparse points.
774 NTFS capture: Capture first unnamed stream if there are more than one
775 (print warning instead of error).
777 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
780 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
783 Update to work with ntfs-3g version 2013.1.13.
786 Fixed truncating file to shorter but non-zero length on read-write
789 Various code cleanups and minor documentation fixes.
792 LZX and XPRESS decompression have received some additional optimizations
793 and should now be even faster. (Although, they were already pretty
794 fast--- much faster than typical I/O speeds.)
796 Fixed a bug introduced in v1.2.1 that would cause a directory tree
797 containing hard links to be captured incorrectly in some cases.
800 By default, unmounting a read-write mounted WIM with 'imagex unmount
801 --commit' will now change the WIM in-place without needing to write the
802 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
805 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
806 for a response from the daemon servicing the mounted WIM. Instead,
807 every second 'imagex unmount' will check if the daemon is still alive,
808 and keep waiting if so, otherwise terminate with an error.
810 'imagex unmount --commit' on a read-write mounted WIM will now print
811 progress information regarding the writing of new or modified streams
812 the WIM, just like when capturing or appending a WIM.
814 A small change has been made to XPRESS compression and it should improve
815 the compression ratio slightly.
817 A change was made that may improve performance slightly when applying a
818 WIM image to a NTFS volume.
820 Microsoft has managed to introduce even more bugs into their software,
821 and now the WIMs for Windows 8 have incorrect (too low) reference counts
822 for some streams. This is unsafe because such streams can be removed
823 when they are in actuality still referenced in the WIM (perhaps by a
824 different image). wimlib will now work around this problem by fixing
825 the stream reference counts. This is only done when wimlib_delete_image() is
826 called ('imagex delete') or when wimlib_mount_image() is called with
827 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
828 requires reading the metadata for all images in the WIM, so this will
829 make these operations noticably slower on WIMs with multiple images.
831 Various other bugfixes.
834 Appending images to a WIM is now be done by default without re-building
835 the whole WIM. Use the --rebuild flag to get the old behavior (which
836 was to re-build the entire WIM when a new image is appended).
838 A new command `imagex optimize' is now available to manually re-build a
839 WIM that has wasted space due to repeated appends.
841 Progress information has been improved, and now arbitrary callback
842 functions can be used to show the progress of a WIM operation.
844 A possible bug with changing the bootable image of a WIM was fixed.
846 Some advisory locking is now done to prevent two processes from
847 modifying a WIM at the same time (but only in some cases). For example,
848 you cannot mount two images from a WIM read-write at the same time.
850 Some functions have been reorganized:
851 * wimlib_mount() renamed to wimlib_mount_image().
852 * wimlib_unmount() renamed to wimlib_unmount_image().
853 * wimlib_overwrite_xml_and_header() removed as
854 wimlib_overwrite() suffices now.
855 * wimlib_apply_image_to_ntfs_volume() removed as
856 wimlib_extract_image() suffices now.
857 * wimlib_add_image_from_ntfs_volume() removed as
858 * wimlib_add_image() suffices now.
860 Previously, the soname of libwim.so has been 0.0.0, despite many
861 interface changes. The soname is now updated to 1.0.0 and will now be
862 updated each release.
865 Resources will now be compressed using multiple threads by default.
866 (This applies to `imagex capture', `imagex append', and `imagex
869 Some performance improvements in mounted WIMs.
871 More progress information is shown when capturing a WIM.
874 Lots of minor fixes, code cleanups, and some documentation updates.
875 Nothing in particular is really noteworthy.
878 LZX and XPRESS compression improvements.
880 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
881 Link Bytes of the WIM.
884 Fixed bug when capturing NTFS file with multiple named data streams.
886 Internally, we are now using inode structures, even though these don't
887 appear literally in the WIM file. This simplifies some of the code
888 (mainly for WIM mounting) and likely fixed a few problems, although it
892 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
896 Enough changes to call it version 1.0.0!
898 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
899 to a NTFS volume, is now supported.
901 Hard links and symbolic links have much improved support. They are
902 supported for WIM capture, WIM application, and mounted WIMs (you can
903 even make them on read-write mounted WIMs).
905 Alternate data streams are now supported on mounted WIMs through an
906 xattr or a Windows-style stream interface. Also they are supported when
907 capturing a WIM from NTFS or applying a WIM to NTFS.
909 Split WIMs are better supported. You may now apply an image directly
910 from a split WIM, mount an image from a split WIM read-only, or export
911 an image from a split WIM.
913 Using a capture configuration file is now supported (but not fully yet).
915 SHA1 message digests are checked in more places, so we can make sure
916 applied and captured data is correct.
918 Man pages have been updated and consolidated.
921 Fixed segfault when unmounting read-only WIM.
924 Support for joining and splitting WIMs.
925 Also, security data is now preserved by default.
928 Can now build with older gcc and system headers, like on CentOS 5.
931 Fixed bug that made it impossible to overwrite files in read-write
935 Write byte-order mark before WIM XML data. (imagex.exe requires this to
