2 Fixed a bug where, on Windows, wimlib would change the security
3 descriptor of the target directory of an extraction even when the
4 '--no-acls' option was specified.
6 Added experimental support for Windows VSS (Volume Shadow Copy Service).
7 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
8 create and use a temporary VSS snapshot when capturing a WIM image.
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.
18 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
19 some Microsoft software would not correctly recognize data in the
22 Made some small improvements to the compression algorithms:
23 LZX compression ratio was slightly improved.
24 XPRESS compression ratio and speed was slightly improved.
25 LZMS compression speed was slightly improved.
27 Improved handling of WIM XML data. wimlib no longer drops unrecognized
28 elements when exporting images. In addition, two API functions were
29 added for better access to elements in the XML document:
30 wimlib_get_image_property() and wimlib_set_image_property().
32 Added support for (unsafe) in-place compaction of WIM files.
34 Improved performance of image export by reusing metadata resources
35 instead of always rebuilding and recompressing them.
37 Improved performance of wimlib_update_image() by delaying the update to
38 the WIM's XML document until a write is requested.
40 On Windows, the target of an extraction may now be a reparse point
41 (which will be dereferenced).
43 On Windows, wimlib now correctly restores non-Microsoft reparse points.
44 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
46 On Windows, wimlib now has improved performance when archiving files
47 from a filesystem backed by a WIM (a "WIMBoot" setup).
49 Several improvements to System Compression (compact mode) support:
51 wof.sys (or wofadk.sys) is now automatically attached to the
52 target volume if needed.
54 Compact-mode extractions now work correctly with wofadk.sys on
55 older versions of Windows.
57 For compatibility with the Windows bootloader, the requested
58 compression format now is overridden on certain files.
63 This release primarily contains various minor bug fixes and
64 improvements, including:
66 Improved handling of deep directory structures.
68 Fixed a bug where on 32-bit systems, the library could enter an
69 infinite loop if a WIM file was malformed in a specific way.
71 Added a workaround for a case where libntfs-3g may report
72 duplicate streams in an NTFS file.
74 Windows symbolic links and junctions in mounted WIM images are
75 now automatically rewritten to be valid in the mounted location.
77 Reparse point fixes: correctly handle the "ReparseReserved"
78 field, and correctly handle "empty" (data-less) reparse points.
80 On Windows, wimlib now acquires SeManageVolumePrivilege, which
81 is needed to create externally backed files using the
84 Improved validation of filenames.
86 Improved LZMS decompression speed.
88 The configure script now honors alternate pkg-config settings.
90 Links have been updated to point to the new website.
92 In addition, experimental support has been added for compressing
93 extracted files using System Compression on Windows 10. This
94 functionality is available through the new '--compact' option to
95 'wimapply' and 'wimextract' as well as new library flags.
98 Fixed a bug in the LZX decompressor: malicious input data could cause
99 out of bounds writes to memory (since wimlib v1.2.2).
101 The output of the 'wiminfo' command now consolidates various boolean
102 flags (such as "Relative path junction") into a single line.
104 A file can now have both an unnamed data stream ("file contents") and a
105 reparse point stream. Such files can exist as a result of the use of
106 certain Windows features, such as offline storage, including "OneDrive".
107 wimlib will now store and restore both streams on Windows as well as in
108 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
110 On Windows, named data streams of encrypted files are no longer stored
111 twice in WIM archives.
113 On Windows, named data streams are now correctly extracted to existing
114 "readonly" directories. Before, an error would be reported.
116 On Windows, it is now possible to do a "WIMBoot mode" extraction with
117 non-standalone WIMs such as delta WIMs.
119 On Windows, when doing an extraction in "WIMBoot mode", files larger
120 than 4 gigabytes are now never extracted as externally backed. This
121 works around a bug in Microsoft's "WOF" driver.
123 The '--enable-verify-compression' configure option has been removed. If
124 you want to verify a WIM file, use the 'wimverify' program.
126 The way the "file count", "directory count", "total bytes", and "hard
127 link bytes" image statistics (stored in the WIM XML data) is calculated
128 has been slightly changed.
130 In mounted WIM images, the disk usage provided for each file (st_blocks)
131 is now the compressed size rather than the uncompressed size.
133 The performance of the NTFS-3g and Windows capture modes has been
136 On UNIX-like systems, symbolic links whose targets contain the backslash
137 character are now handled correctly (losslessly).
140 Improved the LZX compressor. It is now 15-20% faster than before and
141 provides a slightly better compression ratio.
143 Improved the LZMS compressor. It now provides a compression ratio
144 slightly better than WIMGAPI while still being faster and using slightly
147 The compression chunk size in solid resources, e.g. when capturing or
148 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
149 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
150 better compression ratio and is the same value that WIMGAPI uses. The
151 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
152 lower than WIMGAPI's memory usage, but if it is too much, it is still
153 possible to choose a lower value, e.g. with the '--solid-chunk-size'
154 option to wimlib-imagex.
156 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
157 accept the 'K', 'M', and 'G' suffixes.
159 Files are now sorted by name extension when creating a solid WIM file.
161 Fixed various issues related to capture/apply of EFS-encrypted files on
164 The file list printed by 'wimdir' is now sorted by the platform-specific
165 case sensitivity setting, rather than always case sensitively. This
166 also affects the library function wimlib_iterate_dir_tree().
168 On Windows, some error and warning messages have been improved.
171 The Windows binary distribution no longer contains third party DLLs.
172 These dependencies are instead compiled directly into the libwim DLL.
174 Added more fixes for wimlib on non-x86 architectures such as ARM.
176 Extracting files to a Windows PE in-memory filesystem no longer fails if
177 the target files do not yet exist.
179 Improved the performance of XPRESS compression and LZMS decompression.
181 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
182 It will automatically be faster on newer Intel and AMD processors.
184 Removed the --with-imagex-progname and --enable-more-assertions
188 Fix for very slow export from solid WIM / ESD files.
190 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
192 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
193 may use this to treat some types of errors as non-fatal.
195 The library now permits making in-memory changes to a WIMStruct backed
196 by a read-only WIM file.
198 Fixes for "WIMBoot" extraction mode (Windows only):
200 When not using the WOF driver, extraction no longer fails if the
201 disk containing the WIM file has too many partitions.
203 When matching patterns in [PrepopulateList], all hard links of
204 each file are now considered.
206 The system registry files are now automatically treated as being
207 in [PrepopulateList].
209 Added a hack to try to work around an intermittent bug in
210 Microsoft's WOF (Windows Overlay Filesystem) driver.
213 Made more improvements to the XPRESS, LZX, and LZMS compressors.
215 A number of improvements to the Windows port:
217 Fixes for setting short filenames.
219 Faster "WIMBoot" extraction.
221 Updated and slimmed down the dependent DLLs.
223 ACL inheritence bits are now restored.
225 Mandatory integrity labels are now backed up and restored.
227 Added a workaround for an issue where in rare cases, wimlib could create
228 a compressed data stream that could not be read correctly by Windows
229 after an extraction in "WIMBoot" mode.
232 Added file count progress data for
233 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
234 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
236 Added support for testing file exclusions via the user-provided
239 Some documentation improvements.
241 Made some clarifications to the license text in the COPYING file.
244 Made more improvements to the XPRESS, LZX, and LZMS compressors.
246 The default compression mode for wimcapture is now LZX compression in
247 its default mode, which is the same as '--compress=maximum'.
249 You can now specify an optional integer compression level to the
250 '--compress' option; e.g. '--compress=lzx:75'.
252 Made a minor change to the LZMS compressor and decompressor to fix an
253 incompatibility with the Microsoft implementation. In the unlikely
254 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
255 earlier and a checksum error is reported when extracting files from it
256 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
259 Added 'verify' subcommand to wimlib-imagex.
261 Notable library changes:
263 Custom compressor parameters have been removed from the library
264 in favor of the simpler level-based API.
266 Decompressor parameters have been removed entirely.
268 Library users can now specify a custom file for warning and
269 error messages to be sent to, rather than the default of
272 New progress messages:
273 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
274 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
276 New function: wimlib_verify_wim().
279 Improved compression, decompression, and extraction performance.
281 Improved compatibility with version 3584 WIM / ESD files:
282 - Add support for reading and writing multiple solid blocks per
283 archive, which WIMGAPI/DISM can create when appending an image.
284 - Correctly create solid blocks larger than 4 GiB.
286 'add' commands passed to wimupdate will now replace existing
287 nondirectory files by default. Use the --no-replace option to get the
290 The license for the library now contains an exception that allows using
291 it under the LGPL. See the COPYING file for details.
293 In reparse-point fixup mode (the default for capture), symbolic links
294 and junctions that point outside the tree being captured are no longer
295 excluded from capture.
297 Added support for "WIMBoot" capture and extraction. See the
298 documentation for the new '--wimboot' option to wimcapture and wimapply
299 for more information.
301 On UNIX-like systems, you can now backup and restore device nodes, named
302 pipes, and sockets. In addition, 32-bit user and group IDs are now
305 The way that UNIX data is stored in WIM files has been changed. If you
306 captured any WIMs with the --unix-data option, to upgrade them you'll
307 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
308 re-capture them with --unix-data using this version.
310 wimlib now understands tagged metadata items, such as object IDs, that
311 can be stored in WIM directory entries.
313 Removed the --hardlink and --symlink options to wimapply, since I don't
314 think they are too useful and they got in the way of improving the code.
316 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
318 The 'mkwinpeimg' script now supports writing the ISO image to standard
321 The <ARCH> element in WIM XML data is now exported correctly.
323 On Windows, sparse file attributes are no longer set on extracted files.
324 Oddly enough, this actually saves disk space in some cases.
326 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
327 supported. Mounting WIM images now always requires extended attribute
328 support. Use --without-fuse to disable support for mounting WIM images;
329 this will also disable the need for extended attribute support.
331 Configuring with --enable-ssse3-sha1 now works correctly.
333 The shared library version has been bumped up. The main
334 incompatibilities are:
336 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
337 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
340 - User-provided progress functions are now registered using a
341 separate function, wimlib_register_progress_function(). The
342 'progress_func' argument to many functions no longer exists.
344 - The return value from user-provided progress functions is now
347 - A context argument has been added to the prototype of
348 user-provided progress functions.
350 - 'struct wimlib_capture_config' has been removed. The library
351 now takes the path to the configuration file directly. This
352 affects wimlib_add_image(), wimlib_add_image_multisource(),
353 and wimlib_update_image(). However, a NULL value passed in
354 the argument retains the same meaning.
356 - Removed deprecated functions: some (de)compression functions,
357 wimlib_extract_files(), and wimlib_print_metadata().
359 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
360 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
361 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
363 - Removed some progress messages:
364 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
365 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
366 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
369 - Removed some error codes. Numbering stays the same.
371 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
372 WIMLIB_UNMOUNT_FLAG_FORCE.
374 - WIM paths passed to progress functions now have a leading
378 Case-insensitive comparisons of strings (e.g. filenames) containing
379 UTF-16 codepoints above 32767 are now done correctly.
381 Fixed build failure on Mac OS X.
383 wimunmount now provides the '--new-image' option to cause changes to a
384 read-write mounted image to be committed as a new image rather than as
385 an update of the mounted image. (The corresponding new library flag is
386 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
388 The LZMS ("recovery") compression chunk size, or "dictionary size", may
389 now be up to 1 GiB (1,073,741,824 bytes).
391 The performance of LZX ("maximum") and LZMS ("recovery") compression
392 with large chunk sizes has been slightly improved.
395 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
396 decompressed correctly.
398 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
399 occurred in an unlikely case, and due to validity checks it did not
400 affect successfully created archives.
402 Fixed a minor compatibility issue with the LZMS compressor and
403 decompressor. This is *not* the default compression type and was only
404 introduced in v1.6.0. In the unlikely event that you created an
405 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
406 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
409 Memory usage for LZMS and LZX compression has been decreased.
411 wimextract now allows wildcard characters in paths specified on the
412 command line. Also, the '--strict-wildcards' option has been removed
413 and replaced with the inverse option '--nullglob'. See the
414 documentation for wimextract for more details and changes.
416 The wimlib_extract_files() function is now considered deprecated in
417 favor of wimlib_extract_paths().
419 Fixed more permissions problems when extracting files on Windows.
421 A new '--no-attributes' option has been added to wimapply and
422 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
424 The default chunk size is now set correctly when changing the
425 compression type of a WIM, for example with 'wimoptimize'.
427 The '--metadata' option to wiminfo has been replaced with the
428 '--detailed' option to wimdir.
430 In relevant wimlib-imagex commands, '--solid' may now be used as an
431 alias for '--pack-streams'.
434 Support for extracting and updating the new version 3584 WIMs has been
435 added. These WIMs typically pack many streams ("files") together into a
436 single compressed resource, thereby saving space. This degrades the
437 performance of random access (such as that which occurs on a mounted
438 image), but optimizations have been implemented for extraction. These
439 new WIM files also typically use a new compression format (LZMS), which
440 is similar to LZMA and can offer a better compression ratio than LZX.
441 These new WIM files can be created using `wimcapture' with
442 the '--compress=lzms --pack-streams' options. Note: this new WIM format
443 is used by the Windows 8 web downloader, but important segments of the
444 raw '.esd' files are encrypted, so wimlib will not be able to extract
445 such files until they are first decrypted.
447 wimlib now supports extracting files and directories from a WIM image
448 based on a "listfile" that itself contains the list of paths to extract.
449 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
450 and for the library itself, the new APIs are wimlib_extract_pathlist()
451 and wimlib_extract_paths(). Path globs containing wildcard characters
454 For searching WIM files, wimlib now has configurable case sensitivity.
455 The default on Windows is still case-insensitive and the default on
456 UNIX-like systems is still case-sensitive, but this can be overridden
457 on either platform through flags to wimlib_global_init(). For
458 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
459 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
462 Support for compression chunk sizes greater than the default of 32768
463 bytes has been added. A larger chunk size typically results in a better
464 compression ratio. However, the MS implementation is seemingly not
465 compatible with all chunk sizes, especially for LZX compression, so the
466 defaults remain unchanged, with the exception of the new LZMS-compressed
467 WIMs, which use a larger chunk size by default.
469 The compression/decompression API exported by wimlib has been changed.
470 Now one set of functions handles all supported compression formats.
472 `wimcapture' and `wimappend' will now display the progress of scanning
473 the directory tree to capture, in addition to the progress of writing
474 data to the WIM. The '--verbose' option no longer does anything. The
475 library API change for this is the addition of several members to
476 `struct wimlib_progress_info_scan' available to progress callbacks.
478 `mkwinpeimg' now correctly handles the '--start-script' option when the
479 start script is not in the working directory.
481 Sequential extraction, previously requested by using
482 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
483 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
484 behavior (extract in file order).
487 The new LZX compressor added in v1.5.2 has been improved and is now
488 enabled by default, except when `wimcapture' or `wimappend' is run
489 *without* the '--compress' option, in which case the faster LZX
490 compressor is used (the same as before). This behavior is reasonably
491 consistent with ImageX which actually uses "fast" (XPRESS) compression
492 by default. In those cases, use '--compress=maximum' to explicitly
493 capture a WIM image using the new (slower but better) LZX compressor.
495 The '--compress-slow' option still exists to `wimlib-imagex optimize',
496 but its new behavior is to tweak the new LZX compressor even more to
497 produce an even better compression ratio at the cost of more time spent
500 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
501 which recompresses the WIM file using the specified compression TYPE.
502 The new library API function used for this is
503 wimlib_set_output_compression_type().
505 Added the wimlib_get_xml_data() function to allow library clients to
506 easily retrieve the raw XML data from a WIM file if needed.
508 Fixed a bug that could cause an error code to be incorrectly returned
509 when writing XML data containing a <WINDOWS> element.
511 Mounted WIM images will now correctly show the default file stream even
512 if appears in the alternate data stream entries of the corresponding WIM
516 Added a new experimental LZX compressor which can be enabled by passing
517 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
518 optimize'. (The latter is only applicable if the WIM is already
519 LZX-compressed and the '--recompress' option is also given.) The
520 experimental compressor is much slower but compresses the data slightly
521 more --- currently usually to within a fraction of a percent of the
522 results from WIMGAPI/ImageX.
524 A workaround has been added for compatibility with versions of WinPE
525 that interpret alternate data stream entries in the boot WIM
528 An alignment bug that caused a crash in the LZX decompressor on some
531 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
532 the WIM header when restoring the previous state of a WIM it failed to
535 Added a workaround to avoid an access denied error on Windows when
536 replacing a WIM file that another process has opened.
539 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
540 needed to be handled.
542 A bug in the interpretation of negative IMAGE indices in the
543 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
544 `wimlib-imagex append' has been fixed.
546 A workaround has been added to successfully apply security descriptors
547 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
548 2013.1.13 or earlier.
550 `wimlib-imagex capture' can now accept the '--delta-from' option
554 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
555 to standard output and applying images from standard input, but they are
556 not compatible with Microsoft's software and are not created by default.
557 See the documentation for --pipable flag of `wimlib-imagex capture' for
560 To better support incremental backups, added support for declaring an
561 image as a modified form of another image. See the documentation for
562 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
565 Added supported for "delta" WIMs. See the documentation for the
566 '--delta-from' option of `wimlib-imagex capture'.
568 The library support for managing split WIMs has been changed to support
569 other arrangements, such as delta WIMs, and be easier to use. This
570 change is visible in `wimlib-imagex', which also can now accept the
571 '--ref' option multiple times, and also now supports "delta" WIMs as
574 wimlib now preserves WIM integrity tables by default, even if
575 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
576 behavior of `wimlib-imagex' whenever the WIM being operated on contains
577 an integrity table and the '--check' option is not specified.
579 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
580 (when --compress is not specified). This provides the best compression
581 ratio by default, which is usually what is desired, at a cost of some
584 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
585 is the command as in `wimlib-imagex COMMAND'; for example, it can be
586 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
587 appropriate hard links are created in UNIX installations of
588 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
589 batch files that emulate this behavior are generated.
591 Security descriptors are now extracted correctly on Windows.
593 Fixed archiving DOS names in NTFS-3g capture mode.
595 The extraction code has been rewritten and it will now be easier to
596 support new features on all supported backends (currently Win32, UNIX,
597 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
598 now supported on all backends, not just UNIX.
600 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
601 than the WAIK itself.
603 wimlib_global_init() now, by default, attempts to acquire additional
604 privileges on Windows, so library clients need not do this.
606 This update bumps the shared library version number up to 9, since it is
607 not binary compatibible with previous releases.
610 Fixed bug in `wimlib-imagex export' that made it impossible to export an
611 image from a WIM that is readonly at the filesystem level.
613 Return error code rather than segfaulting when trying to list files from
614 a non-first part of a split WIM.
616 Joining a WIM will now preserve the RP_FIX and READONLY flags.
619 On Windows, paths given to wimlib-imagex are now treated case
622 Improved behavior regarding invalid filenames; in particular, on
623 Windows, wimlib-imagex will, when extracting, now omit (with an option
624 to override this default) filenames differing only in case, or filenames
625 containing characters not valid on Windows.
627 On Windows, wimlib now supports capturing and extracting long paths
628 (longer than the so-called MAX_PATH).
630 On Windows, `wimlib-imagex update' now acquires proper privileges when
631 running as an Administrator.
633 `wimlib-imagex update' will now complain if no image is specified when
634 trying to update a multi-image WIM.
636 `wimlib-imagex update' now supports specifying a single update command
637 directly on the command line using the --command option.
639 wimlib-imagex will now choose different units for progress messages,
640 depending on the amount of data that needs to be processed.
642 `wimlib-imagex append' will now generate a unique WIM image name if no
643 name is specified and the defaulted name already exists in the WIM.
645 wimlib now allows you to create unnamed WIM images, which can then only
646 be referred to by index.
648 wimlib now allows you to explicitly declare you want write access to a
649 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
652 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
655 Progress callbacks have been added to wimlib's wimlib_update_image()
658 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
659 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
662 NTFS-3g capture now only warns about two conditions previously treated
665 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
668 wimlib now correctly detects and returns an error when reading a WIM
669 image with a cyclic directory structure. (Fun fact: such a WIM will
670 crash Microsoft's software.)
673 Added new "extract" and "update" subcommands to wimlib-imagex, along
674 with associated APIs in the library. These commands are intended mainly
675 for Windows use but can be used on UNIX as well.
677 Many documentation improvements.
679 Fixed a bug in the Windows build where relative symbolic links were not
680 captured in reparse-point fixup mode.
682 Fixed a bug in the Windows build where file handles were left open to
683 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
685 Fixed a bug in the Windows build of wimlib-imagex where globbing
686 split-WIM parts could cause the program to crash.
688 Fixed a bug where the creation time of WIM images would be shown instead
689 of the last modification time.
691 With the Windows build it is now possible to restore a WIM containing
692 symbolic links as a non-Administrator; however you will receive warnings
693 about not being able to extract the symbolic links.
696 Capturing a WIM image should now be significantly faster in most cases
697 due to improved use of the operating system's cache and avoiding reading
698 files twice whenever possible.
700 The Windows build should now work on Windows XP.
702 The Windows build now supports capturing and restoring hidden,
703 compressed, sparse, and encrypted files.
705 The Windows build now supports capturing and applying WIM images from
706 filesystems other than NTFS (with some reduced functionality).
708 The Windows build now extracts short names correctly.
710 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
711 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
712 capture' and `wimlib-imagex apply'.
714 The performance of splitting and joining WIMs should be slightly
717 The LZX and XPRESS compression and decompression functions are now
718 exported from the library.
721 Improvements and bugfixes for the Windows build.
723 Added --strict-acls options.
725 Fixed the way that wimlib determines the order of images in the WIM.
728 Since wimlib can now be used on Windows, wimlib's implementation of
729 ImageX has been renamed to wimlib-imagex to avoid confusion with
730 Microsoft's implementation of ImageX, which would have the same file
731 name ("imagex.exe"). If you really don't like this you can pass the
732 --with-imagex-progname option to `configure' to choose a different name,
733 or even simply rename the binary yourself (but the former way will
734 configure the man pages to use the chosen name).
736 Various bugs fixed in the Windows build. Mainly to do with capturing
737 and restoring alternate data streams correctly in weird cases, and
738 requesting the correct privileges when opening files. Also added the
739 --noacls options to wimlib-imagex capture, append, and apply.
741 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
742 dynamically loaded, so this may make the library compatible with Windows
743 XP (however, there may still be other problems).
746 Added experimental support for native Windows builds. Binaries can be
747 downloaded from the SourceForge page.
749 --source-list option added to `imagex capture' and `imagex append'.
751 Better support for different character encodings.
754 Storing UNIX file owners, groups, and modes in WIM images is now
755 possible using `imagex capture' with the --unix-data flag.
757 Minor bug fixes and documentation fixes.
760 NTFS capture: Fixed capturing duplicate reparse points.
762 NTFS capture: Capture first unnamed stream if there are more than one
763 (print warning instead of error).
765 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
768 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
771 Update to work with ntfs-3g version 2013.1.13.
774 Fixed truncating file to shorter but non-zero length on read-write
777 Various code cleanups and minor documentation fixes.
780 LZX and XPRESS decompression have received some additional optimizations
781 and should now be even faster. (Although, they were already pretty
782 fast--- much faster than typical I/O speeds.)
784 Fixed a bug introduced in v1.2.1 that would cause a directory tree
785 containing hard links to be captured incorrectly in some cases.
788 By default, unmounting a read-write mounted WIM with 'imagex unmount
789 --commit' will now change the WIM in-place without needing to write the
790 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
793 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
794 for a response from the daemon servicing the mounted WIM. Instead,
795 every second 'imagex unmount' will check if the daemon is still alive,
796 and keep waiting if so, otherwise terminate with an error.
798 'imagex unmount --commit' on a read-write mounted WIM will now print
799 progress information regarding the writing of new or modified streams
800 the WIM, just like when capturing or appending a WIM.
802 A small change has been made to XPRESS compression and it should improve
803 the compression ratio slightly.
805 A change was made that may improve performance slightly when applying a
806 WIM image to a NTFS volume.
808 Microsoft has managed to introduce even more bugs into their software,
809 and now the WIMs for Windows 8 have incorrect (too low) reference counts
810 for some streams. This is unsafe because such streams can be removed
811 when they are in actuality still referenced in the WIM (perhaps by a
812 different image). wimlib will now work around this problem by fixing
813 the stream reference counts. This is only done when wimlib_delete_image() is
814 called ('imagex delete') or when wimlib_mount_image() is called with
815 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
816 requires reading the metadata for all images in the WIM, so this will
817 make these operations noticably slower on WIMs with multiple images.
819 Various other bugfixes.
822 Appending images to a WIM is now be done by default without re-building
823 the whole WIM. Use the --rebuild flag to get the old behavior (which
824 was to re-build the entire WIM when a new image is appended).
826 A new command `imagex optimize' is now available to manually re-build a
827 WIM that has wasted space due to repeated appends.
829 Progress information has been improved, and now arbitrary callback
830 functions can be used to show the progress of a WIM operation.
832 A possible bug with changing the bootable image of a WIM was fixed.
834 Some advisory locking is now done to prevent two processes from
835 modifying a WIM at the same time (but only in some cases). For example,
836 you cannot mount two images from a WIM read-write at the same time.
838 Some functions have been reorganized:
839 * wimlib_mount() renamed to wimlib_mount_image().
840 * wimlib_unmount() renamed to wimlib_unmount_image().
841 * wimlib_overwrite_xml_and_header() removed as
842 wimlib_overwrite() suffices now.
843 * wimlib_apply_image_to_ntfs_volume() removed as
844 wimlib_extract_image() suffices now.
845 * wimlib_add_image_from_ntfs_volume() removed as
846 * wimlib_add_image() suffices now.
848 Previously, the soname of libwim.so has been 0.0.0, despite many
849 interface changes. The soname is now updated to 1.0.0 and will now be
850 updated each release.
853 Resources will now be compressed using multiple threads by default.
854 (This applies to `imagex capture', `imagex append', and `imagex
857 Some performance improvements in mounted WIMs.
859 More progress information is shown when capturing a WIM.
862 Lots of minor fixes, code cleanups, and some documentation updates.
863 Nothing in particular is really noteworthy.
866 LZX and XPRESS compression improvements.
868 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
869 Link Bytes of the WIM.
872 Fixed bug when capturing NTFS file with multiple named data streams.
874 Internally, we are now using inode structures, even though these don't
875 appear literally in the WIM file. This simplifies some of the code
876 (mainly for WIM mounting) and likely fixed a few problems, although it
880 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
884 Enough changes to call it version 1.0.0!
886 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
887 to a NTFS volume, is now supported.
889 Hard links and symbolic links have much improved support. They are
890 supported for WIM capture, WIM application, and mounted WIMs (you can
891 even make them on read-write mounted WIMs).
893 Alternate data streams are now supported on mounted WIMs through an
894 xattr or a Windows-style stream interface. Also they are supported when
895 capturing a WIM from NTFS or applying a WIM to NTFS.
897 Split WIMs are better supported. You may now apply an image directly
898 from a split WIM, mount an image from a split WIM read-only, or export
899 an image from a split WIM.
901 Using a capture configuration file is now supported (but not fully yet).
903 SHA1 message digests are checked in more places, so we can make sure
904 applied and captured data is correct.
906 Man pages have been updated and consolidated.
909 Fixed segfault when unmounting read-only WIM.
912 Support for joining and splitting WIMs.
913 Also, security data is now preserved by default.
916 Can now build with older gcc and system headers, like on CentOS 5.
919 Fixed bug that made it impossible to overwrite files in read-write
923 Write byte-order mark before WIM XML data. (imagex.exe requires this to
