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 a new '--image-property' option to 'wimcapture', 'wimappend', and
7 'wiminfo'. This option lets you assign values to elements in a WIM
8 file's XML document by name.
10 The wimlib_get_image_property() and wimlib_set_image_property() API
11 functions now support numerically indexed elements.
14 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
15 some Microsoft software would not correctly recognize data in the
18 Made some small improvements to the compression algorithms:
19 LZX compression ratio was slightly improved.
20 XPRESS compression ratio and speed was slightly improved.
21 LZMS compression speed was slightly improved.
23 Improved handling of WIM XML data. wimlib no longer drops unrecognized
24 elements when exporting images. In addition, two API functions were
25 added for better access to elements in the XML document:
26 wimlib_get_image_property() and wimlib_set_image_property().
28 Added support for (unsafe) in-place compaction of WIM files.
30 Improved performance of image export by reusing metadata resources
31 instead of always rebuilding and recompressing them.
33 Improved performance of wimlib_update_image() by delaying the update to
34 the WIM's XML document until a write is requested.
36 On Windows, the target of an extraction may now be a reparse point
37 (which will be dereferenced).
39 On Windows, wimlib now correctly restores non-Microsoft reparse points.
40 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
42 On Windows, wimlib now has improved performance when archiving files
43 from a filesystem backed by a WIM (a "WIMBoot" setup).
45 Several improvements to System Compression (compact mode) support:
47 wof.sys (or wofadk.sys) is now automatically attached to the
48 target volume if needed.
50 Compact-mode extractions now work correctly with wofadk.sys on
51 older versions of Windows.
53 For compatibility with the Windows bootloader, the requested
54 compression format now is overridden on certain files.
59 This release primarily contains various minor bug fixes and
60 improvements, including:
62 Improved handling of deep directory structures.
64 Fixed a bug where on 32-bit systems, the library could enter an
65 infinite loop if a WIM file was malformed in a specific way.
67 Added a workaround for a case where libntfs-3g may report
68 duplicate streams in an NTFS file.
70 Windows symbolic links and junctions in mounted WIM images are
71 now automatically rewritten to be valid in the mounted location.
73 Reparse point fixes: correctly handle the "ReparseReserved"
74 field, and correctly handle "empty" (data-less) reparse points.
76 On Windows, wimlib now acquires SeManageVolumePrivilege, which
77 is needed to create externally backed files using the
80 Improved validation of filenames.
82 Improved LZMS decompression speed.
84 The configure script now honors alternate pkg-config settings.
86 Links have been updated to point to the new website.
88 In addition, experimental support has been added for compressing
89 extracted files using System Compression on Windows 10. This
90 functionality is available through the new '--compact' option to
91 'wimapply' and 'wimextract' as well as new library flags.
94 Fixed a bug in the LZX decompressor: malicious input data could cause
95 out of bounds writes to memory (since wimlib v1.2.2).
97 The output of the 'wiminfo' command now consolidates various boolean
98 flags (such as "Relative path junction") into a single line.
100 A file can now have both an unnamed data stream ("file contents") and a
101 reparse point stream. Such files can exist as a result of the use of
102 certain Windows features, such as offline storage, including "OneDrive".
103 wimlib will now store and restore both streams on Windows as well as in
104 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
106 On Windows, named data streams of encrypted files are no longer stored
107 twice in WIM archives.
109 On Windows, named data streams are now correctly extracted to existing
110 "readonly" directories. Before, an error would be reported.
112 On Windows, it is now possible to do a "WIMBoot mode" extraction with
113 non-standalone WIMs such as delta WIMs.
115 On Windows, when doing an extraction in "WIMBoot mode", files larger
116 than 4 gigabytes are now never extracted as externally backed. This
117 works around a bug in Microsoft's "WOF" driver.
119 The '--enable-verify-compression' configure option has been removed. If
120 you want to verify a WIM file, use the 'wimverify' program.
122 The way the "file count", "directory count", "total bytes", and "hard
123 link bytes" image statistics (stored in the WIM XML data) is calculated
124 has been slightly changed.
126 In mounted WIM images, the disk usage provided for each file (st_blocks)
127 is now the compressed size rather than the uncompressed size.
129 The performance of the NTFS-3g and Windows capture modes has been
132 On UNIX-like systems, symbolic links whose targets contain the backslash
133 character are now handled correctly (losslessly).
136 Improved the LZX compressor. It is now 15-20% faster than before and
137 provides a slightly better compression ratio.
139 Improved the LZMS compressor. It now provides a compression ratio
140 slightly better than WIMGAPI while still being faster and using slightly
143 The compression chunk size in solid resources, e.g. when capturing or
144 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
145 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
146 better compression ratio and is the same value that WIMGAPI uses. The
147 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
148 lower than WIMGAPI's memory usage, but if it is too much, it is still
149 possible to choose a lower value, e.g. with the '--solid-chunk-size'
150 option to wimlib-imagex.
152 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
153 accept the 'K', 'M', and 'G' suffixes.
155 Files are now sorted by name extension when creating a solid WIM file.
157 Fixed various issues related to capture/apply of EFS-encrypted files on
160 The file list printed by 'wimdir' is now sorted by the platform-specific
161 case sensitivity setting, rather than always case sensitively. This
162 also affects the library function wimlib_iterate_dir_tree().
164 On Windows, some error and warning messages have been improved.
167 The Windows binary distribution no longer contains third party DLLs.
168 These dependencies are instead compiled directly into the libwim DLL.
170 Added more fixes for wimlib on non-x86 architectures such as ARM.
172 Extracting files to a Windows PE in-memory filesystem no longer fails if
173 the target files do not yet exist.
175 Improved the performance of XPRESS compression and LZMS decompression.
177 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
178 It will automatically be faster on newer Intel and AMD processors.
180 Removed the --with-imagex-progname and --enable-more-assertions
184 Fix for very slow export from solid WIM / ESD files.
186 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
188 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
189 may use this to treat some types of errors as non-fatal.
191 The library now permits making in-memory changes to a WIMStruct backed
192 by a read-only WIM file.
194 Fixes for "WIMBoot" extraction mode (Windows only):
196 When not using the WOF driver, extraction no longer fails if the
197 disk containing the WIM file has too many partitions.
199 When matching patterns in [PrepopulateList], all hard links of
200 each file are now considered.
202 The system registry files are now automatically treated as being
203 in [PrepopulateList].
205 Added a hack to try to work around an intermittent bug in
206 Microsoft's WOF (Windows Overlay Filesystem) driver.
209 Made more improvements to the XPRESS, LZX, and LZMS compressors.
211 A number of improvements to the Windows port:
213 Fixes for setting short filenames.
215 Faster "WIMBoot" extraction.
217 Updated and slimmed down the dependent DLLs.
219 ACL inheritence bits are now restored.
221 Mandatory integrity labels are now backed up and restored.
223 Added a workaround for an issue where in rare cases, wimlib could create
224 a compressed data stream that could not be read correctly by Windows
225 after an extraction in "WIMBoot" mode.
228 Added file count progress data for
229 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
230 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
232 Added support for testing file exclusions via the user-provided
235 Some documentation improvements.
237 Made some clarifications to the license text in the COPYING file.
240 Made more improvements to the XPRESS, LZX, and LZMS compressors.
242 The default compression mode for wimcapture is now LZX compression in
243 its default mode, which is the same as '--compress=maximum'.
245 You can now specify an optional integer compression level to the
246 '--compress' option; e.g. '--compress=lzx:75'.
248 Made a minor change to the LZMS compressor and decompressor to fix an
249 incompatibility with the Microsoft implementation. In the unlikely
250 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
251 earlier and a checksum error is reported when extracting files from it
252 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
255 Added 'verify' subcommand to wimlib-imagex.
257 Notable library changes:
259 Custom compressor parameters have been removed from the library
260 in favor of the simpler level-based API.
262 Decompressor parameters have been removed entirely.
264 Library users can now specify a custom file for warning and
265 error messages to be sent to, rather than the default of
268 New progress messages:
269 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
270 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
272 New function: wimlib_verify_wim().
275 Improved compression, decompression, and extraction performance.
277 Improved compatibility with version 3584 WIM / ESD files:
278 - Add support for reading and writing multiple solid blocks per
279 archive, which WIMGAPI/DISM can create when appending an image.
280 - Correctly create solid blocks larger than 4 GiB.
282 'add' commands passed to wimupdate will now replace existing
283 nondirectory files by default. Use the --no-replace option to get the
286 The license for the library now contains an exception that allows using
287 it under the LGPL. See the COPYING file for details.
289 In reparse-point fixup mode (the default for capture), symbolic links
290 and junctions that point outside the tree being captured are no longer
291 excluded from capture.
293 Added support for "WIMBoot" capture and extraction. See the
294 documentation for the new '--wimboot' option to wimcapture and wimapply
295 for more information.
297 On UNIX-like systems, you can now backup and restore device nodes, named
298 pipes, and sockets. In addition, 32-bit user and group IDs are now
301 The way that UNIX data is stored in WIM files has been changed. If you
302 captured any WIMs with the --unix-data option, to upgrade them you'll
303 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
304 re-capture them with --unix-data using this version.
306 wimlib now understands tagged metadata items, such as object IDs, that
307 can be stored in WIM directory entries.
309 Removed the --hardlink and --symlink options to wimapply, since I don't
310 think they are too useful and they got in the way of improving the code.
312 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
314 The 'mkwinpeimg' script now supports writing the ISO image to standard
317 The <ARCH> element in WIM XML data is now exported correctly.
319 On Windows, sparse file attributes are no longer set on extracted files.
320 Oddly enough, this actually saves disk space in some cases.
322 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
323 supported. Mounting WIM images now always requires extended attribute
324 support. Use --without-fuse to disable support for mounting WIM images;
325 this will also disable the need for extended attribute support.
327 Configuring with --enable-ssse3-sha1 now works correctly.
329 The shared library version has been bumped up. The main
330 incompatibilities are:
332 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
333 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
336 - User-provided progress functions are now registered using a
337 separate function, wimlib_register_progress_function(). The
338 'progress_func' argument to many functions no longer exists.
340 - The return value from user-provided progress functions is now
343 - A context argument has been added to the prototype of
344 user-provided progress functions.
346 - 'struct wimlib_capture_config' has been removed. The library
347 now takes the path to the configuration file directly. This
348 affects wimlib_add_image(), wimlib_add_image_multisource(),
349 and wimlib_update_image(). However, a NULL value passed in
350 the argument retains the same meaning.
352 - Removed deprecated functions: some (de)compression functions,
353 wimlib_extract_files(), and wimlib_print_metadata().
355 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
356 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
357 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
359 - Removed some progress messages:
360 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
361 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
362 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
365 - Removed some error codes. Numbering stays the same.
367 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
368 WIMLIB_UNMOUNT_FLAG_FORCE.
370 - WIM paths passed to progress functions now have a leading
374 Case-insensitive comparisons of strings (e.g. filenames) containing
375 UTF-16 codepoints above 32767 are now done correctly.
377 Fixed build failure on Mac OS X.
379 wimunmount now provides the '--new-image' option to cause changes to a
380 read-write mounted image to be committed as a new image rather than as
381 an update of the mounted image. (The corresponding new library flag is
382 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
384 The LZMS ("recovery") compression chunk size, or "dictionary size", may
385 now be up to 1 GiB (1,073,741,824 bytes).
387 The performance of LZX ("maximum") and LZMS ("recovery") compression
388 with large chunk sizes has been slightly improved.
391 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
392 decompressed correctly.
394 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
395 occurred in an unlikely case, and due to validity checks it did not
396 affect successfully created archives.
398 Fixed a minor compatibility issue with the LZMS compressor and
399 decompressor. This is *not* the default compression type and was only
400 introduced in v1.6.0. In the unlikely event that you created an
401 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
402 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
405 Memory usage for LZMS and LZX compression has been decreased.
407 wimextract now allows wildcard characters in paths specified on the
408 command line. Also, the '--strict-wildcards' option has been removed
409 and replaced with the inverse option '--nullglob'. See the
410 documentation for wimextract for more details and changes.
412 The wimlib_extract_files() function is now considered deprecated in
413 favor of wimlib_extract_paths().
415 Fixed more permissions problems when extracting files on Windows.
417 A new '--no-attributes' option has been added to wimapply and
418 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
420 The default chunk size is now set correctly when changing the
421 compression type of a WIM, for example with 'wimoptimize'.
423 The '--metadata' option to wiminfo has been replaced with the
424 '--detailed' option to wimdir.
426 In relevant wimlib-imagex commands, '--solid' may now be used as an
427 alias for '--pack-streams'.
430 Support for extracting and updating the new version 3584 WIMs has been
431 added. These WIMs typically pack many streams ("files") together into a
432 single compressed resource, thereby saving space. This degrades the
433 performance of random access (such as that which occurs on a mounted
434 image), but optimizations have been implemented for extraction. These
435 new WIM files also typically use a new compression format (LZMS), which
436 is similar to LZMA and can offer a better compression ratio than LZX.
437 These new WIM files can be created using `wimcapture' with
438 the '--compress=lzms --pack-streams' options. Note: this new WIM format
439 is used by the Windows 8 web downloader, but important segments of the
440 raw '.esd' files are encrypted, so wimlib will not be able to extract
441 such files until they are first decrypted.
443 wimlib now supports extracting files and directories from a WIM image
444 based on a "listfile" that itself contains the list of paths to extract.
445 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
446 and for the library itself, the new APIs are wimlib_extract_pathlist()
447 and wimlib_extract_paths(). Path globs containing wildcard characters
450 For searching WIM files, wimlib now has configurable case sensitivity.
451 The default on Windows is still case-insensitive and the default on
452 UNIX-like systems is still case-sensitive, but this can be overridden
453 on either platform through flags to wimlib_global_init(). For
454 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
455 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
458 Support for compression chunk sizes greater than the default of 32768
459 bytes has been added. A larger chunk size typically results in a better
460 compression ratio. However, the MS implementation is seemingly not
461 compatible with all chunk sizes, especially for LZX compression, so the
462 defaults remain unchanged, with the exception of the new LZMS-compressed
463 WIMs, which use a larger chunk size by default.
465 The compression/decompression API exported by wimlib has been changed.
466 Now one set of functions handles all supported compression formats.
468 `wimcapture' and `wimappend' will now display the progress of scanning
469 the directory tree to capture, in addition to the progress of writing
470 data to the WIM. The '--verbose' option no longer does anything. The
471 library API change for this is the addition of several members to
472 `struct wimlib_progress_info_scan' available to progress callbacks.
474 `mkwinpeimg' now correctly handles the '--start-script' option when the
475 start script is not in the working directory.
477 Sequential extraction, previously requested by using
478 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
479 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
480 behavior (extract in file order).
483 The new LZX compressor added in v1.5.2 has been improved and is now
484 enabled by default, except when `wimcapture' or `wimappend' is run
485 *without* the '--compress' option, in which case the faster LZX
486 compressor is used (the same as before). This behavior is reasonably
487 consistent with ImageX which actually uses "fast" (XPRESS) compression
488 by default. In those cases, use '--compress=maximum' to explicitly
489 capture a WIM image using the new (slower but better) LZX compressor.
491 The '--compress-slow' option still exists to `wimlib-imagex optimize',
492 but its new behavior is to tweak the new LZX compressor even more to
493 produce an even better compression ratio at the cost of more time spent
496 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
497 which recompresses the WIM file using the specified compression TYPE.
498 The new library API function used for this is
499 wimlib_set_output_compression_type().
501 Added the wimlib_get_xml_data() function to allow library clients to
502 easily retrieve the raw XML data from a WIM file if needed.
504 Fixed a bug that could cause an error code to be incorrectly returned
505 when writing XML data containing a <WINDOWS> element.
507 Mounted WIM images will now correctly show the default file stream even
508 if appears in the alternate data stream entries of the corresponding WIM
512 Added a new experimental LZX compressor which can be enabled by passing
513 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
514 optimize'. (The latter is only applicable if the WIM is already
515 LZX-compressed and the '--recompress' option is also given.) The
516 experimental compressor is much slower but compresses the data slightly
517 more --- currently usually to within a fraction of a percent of the
518 results from WIMGAPI/ImageX.
520 A workaround has been added for compatibility with versions of WinPE
521 that interpret alternate data stream entries in the boot WIM
524 An alignment bug that caused a crash in the LZX decompressor on some
527 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
528 the WIM header when restoring the previous state of a WIM it failed to
531 Added a workaround to avoid an access denied error on Windows when
532 replacing a WIM file that another process has opened.
535 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
536 needed to be handled.
538 A bug in the interpretation of negative IMAGE indices in the
539 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
540 `wimlib-imagex append' has been fixed.
542 A workaround has been added to successfully apply security descriptors
543 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
544 2013.1.13 or earlier.
546 `wimlib-imagex capture' can now accept the '--delta-from' option
550 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
551 to standard output and applying images from standard input, but they are
552 not compatible with Microsoft's software and are not created by default.
553 See the documentation for --pipable flag of `wimlib-imagex capture' for
556 To better support incremental backups, added support for declaring an
557 image as a modified form of another image. See the documentation for
558 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
561 Added supported for "delta" WIMs. See the documentation for the
562 '--delta-from' option of `wimlib-imagex capture'.
564 The library support for managing split WIMs has been changed to support
565 other arrangements, such as delta WIMs, and be easier to use. This
566 change is visible in `wimlib-imagex', which also can now accept the
567 '--ref' option multiple times, and also now supports "delta" WIMs as
570 wimlib now preserves WIM integrity tables by default, even if
571 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
572 behavior of `wimlib-imagex' whenever the WIM being operated on contains
573 an integrity table and the '--check' option is not specified.
575 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
576 (when --compress is not specified). This provides the best compression
577 ratio by default, which is usually what is desired, at a cost of some
580 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
581 is the command as in `wimlib-imagex COMMAND'; for example, it can be
582 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
583 appropriate hard links are created in UNIX installations of
584 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
585 batch files that emulate this behavior are generated.
587 Security descriptors are now extracted correctly on Windows.
589 Fixed archiving DOS names in NTFS-3g capture mode.
591 The extraction code has been rewritten and it will now be easier to
592 support new features on all supported backends (currently Win32, UNIX,
593 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
594 now supported on all backends, not just UNIX.
596 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
597 than the WAIK itself.
599 wimlib_global_init() now, by default, attempts to acquire additional
600 privileges on Windows, so library clients need not do this.
602 This update bumps the shared library version number up to 9, since it is
603 not binary compatibible with previous releases.
606 Fixed bug in `wimlib-imagex export' that made it impossible to export an
607 image from a WIM that is readonly at the filesystem level.
609 Return error code rather than segfaulting when trying to list files from
610 a non-first part of a split WIM.
612 Joining a WIM will now preserve the RP_FIX and READONLY flags.
615 On Windows, paths given to wimlib-imagex are now treated case
618 Improved behavior regarding invalid filenames; in particular, on
619 Windows, wimlib-imagex will, when extracting, now omit (with an option
620 to override this default) filenames differing only in case, or filenames
621 containing characters not valid on Windows.
623 On Windows, wimlib now supports capturing and extracting long paths
624 (longer than the so-called MAX_PATH).
626 On Windows, `wimlib-imagex update' now acquires proper privileges when
627 running as an Administrator.
629 `wimlib-imagex update' will now complain if no image is specified when
630 trying to update a multi-image WIM.
632 `wimlib-imagex update' now supports specifying a single update command
633 directly on the command line using the --command option.
635 wimlib-imagex will now choose different units for progress messages,
636 depending on the amount of data that needs to be processed.
638 `wimlib-imagex append' will now generate a unique WIM image name if no
639 name is specified and the defaulted name already exists in the WIM.
641 wimlib now allows you to create unnamed WIM images, which can then only
642 be referred to by index.
644 wimlib now allows you to explicitly declare you want write access to a
645 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
648 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
651 Progress callbacks have been added to wimlib's wimlib_update_image()
654 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
655 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
658 NTFS-3g capture now only warns about two conditions previously treated
661 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
664 wimlib now correctly detects and returns an error when reading a WIM
665 image with a cyclic directory structure. (Fun fact: such a WIM will
666 crash Microsoft's software.)
669 Added new "extract" and "update" subcommands to wimlib-imagex, along
670 with associated APIs in the library. These commands are intended mainly
671 for Windows use but can be used on UNIX as well.
673 Many documentation improvements.
675 Fixed a bug in the Windows build where relative symbolic links were not
676 captured in reparse-point fixup mode.
678 Fixed a bug in the Windows build where file handles were left open to
679 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
681 Fixed a bug in the Windows build of wimlib-imagex where globbing
682 split-WIM parts could cause the program to crash.
684 Fixed a bug where the creation time of WIM images would be shown instead
685 of the last modification time.
687 With the Windows build it is now possible to restore a WIM containing
688 symbolic links as a non-Administrator; however you will receive warnings
689 about not being able to extract the symbolic links.
692 Capturing a WIM image should now be significantly faster in most cases
693 due to improved use of the operating system's cache and avoiding reading
694 files twice whenever possible.
696 The Windows build should now work on Windows XP.
698 The Windows build now supports capturing and restoring hidden,
699 compressed, sparse, and encrypted files.
701 The Windows build now supports capturing and applying WIM images from
702 filesystems other than NTFS (with some reduced functionality).
704 The Windows build now extracts short names correctly.
706 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
707 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
708 capture' and `wimlib-imagex apply'.
710 The performance of splitting and joining WIMs should be slightly
713 The LZX and XPRESS compression and decompression functions are now
714 exported from the library.
717 Improvements and bugfixes for the Windows build.
719 Added --strict-acls options.
721 Fixed the way that wimlib determines the order of images in the WIM.
724 Since wimlib can now be used on Windows, wimlib's implementation of
725 ImageX has been renamed to wimlib-imagex to avoid confusion with
726 Microsoft's implementation of ImageX, which would have the same file
727 name ("imagex.exe"). If you really don't like this you can pass the
728 --with-imagex-progname option to `configure' to choose a different name,
729 or even simply rename the binary yourself (but the former way will
730 configure the man pages to use the chosen name).
732 Various bugs fixed in the Windows build. Mainly to do with capturing
733 and restoring alternate data streams correctly in weird cases, and
734 requesting the correct privileges when opening files. Also added the
735 --noacls options to wimlib-imagex capture, append, and apply.
737 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
738 dynamically loaded, so this may make the library compatible with Windows
739 XP (however, there may still be other problems).
742 Added experimental support for native Windows builds. Binaries can be
743 downloaded from the SourceForge page.
745 --source-list option added to `imagex capture' and `imagex append'.
747 Better support for different character encodings.
750 Storing UNIX file owners, groups, and modes in WIM images is now
751 possible using `imagex capture' with the --unix-data flag.
753 Minor bug fixes and documentation fixes.
756 NTFS capture: Fixed capturing duplicate reparse points.
758 NTFS capture: Capture first unnamed stream if there are more than one
759 (print warning instead of error).
761 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
764 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
767 Update to work with ntfs-3g version 2013.1.13.
770 Fixed truncating file to shorter but non-zero length on read-write
773 Various code cleanups and minor documentation fixes.
776 LZX and XPRESS decompression have received some additional optimizations
777 and should now be even faster. (Although, they were already pretty
778 fast--- much faster than typical I/O speeds.)
780 Fixed a bug introduced in v1.2.1 that would cause a directory tree
781 containing hard links to be captured incorrectly in some cases.
784 By default, unmounting a read-write mounted WIM with 'imagex unmount
785 --commit' will now change the WIM in-place without needing to write the
786 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
789 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
790 for a response from the daemon servicing the mounted WIM. Instead,
791 every second 'imagex unmount' will check if the daemon is still alive,
792 and keep waiting if so, otherwise terminate with an error.
794 'imagex unmount --commit' on a read-write mounted WIM will now print
795 progress information regarding the writing of new or modified streams
796 the WIM, just like when capturing or appending a WIM.
798 A small change has been made to XPRESS compression and it should improve
799 the compression ratio slightly.
801 A change was made that may improve performance slightly when applying a
802 WIM image to a NTFS volume.
804 Microsoft has managed to introduce even more bugs into their software,
805 and now the WIMs for Windows 8 have incorrect (too low) reference counts
806 for some streams. This is unsafe because such streams can be removed
807 when they are in actuality still referenced in the WIM (perhaps by a
808 different image). wimlib will now work around this problem by fixing
809 the stream reference counts. This is only done when wimlib_delete_image() is
810 called ('imagex delete') or when wimlib_mount_image() is called with
811 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
812 requires reading the metadata for all images in the WIM, so this will
813 make these operations noticably slower on WIMs with multiple images.
815 Various other bugfixes.
818 Appending images to a WIM is now be done by default without re-building
819 the whole WIM. Use the --rebuild flag to get the old behavior (which
820 was to re-build the entire WIM when a new image is appended).
822 A new command `imagex optimize' is now available to manually re-build a
823 WIM that has wasted space due to repeated appends.
825 Progress information has been improved, and now arbitrary callback
826 functions can be used to show the progress of a WIM operation.
828 A possible bug with changing the bootable image of a WIM was fixed.
830 Some advisory locking is now done to prevent two processes from
831 modifying a WIM at the same time (but only in some cases). For example,
832 you cannot mount two images from a WIM read-write at the same time.
834 Some functions have been reorganized:
835 * wimlib_mount() renamed to wimlib_mount_image().
836 * wimlib_unmount() renamed to wimlib_unmount_image().
837 * wimlib_overwrite_xml_and_header() removed as
838 wimlib_overwrite() suffices now.
839 * wimlib_apply_image_to_ntfs_volume() removed as
840 wimlib_extract_image() suffices now.
841 * wimlib_add_image_from_ntfs_volume() removed as
842 * wimlib_add_image() suffices now.
844 Previously, the soname of libwim.so has been 0.0.0, despite many
845 interface changes. The soname is now updated to 1.0.0 and will now be
846 updated each release.
849 Resources will now be compressed using multiple threads by default.
850 (This applies to `imagex capture', `imagex append', and `imagex
853 Some performance improvements in mounted WIMs.
855 More progress information is shown when capturing a WIM.
858 Lots of minor fixes, code cleanups, and some documentation updates.
859 Nothing in particular is really noteworthy.
862 LZX and XPRESS compression improvements.
864 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
865 Link Bytes of the WIM.
868 Fixed bug when capturing NTFS file with multiple named data streams.
870 Internally, we are now using inode structures, even though these don't
871 appear literally in the WIM file. This simplifies some of the code
872 (mainly for WIM mounting) and likely fixed a few problems, although it
876 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
880 Enough changes to call it version 1.0.0!
882 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
883 to a NTFS volume, is now supported.
885 Hard links and symbolic links have much improved support. They are
886 supported for WIM capture, WIM application, and mounted WIMs (you can
887 even make them on read-write mounted WIMs).
889 Alternate data streams are now supported on mounted WIMs through an
890 xattr or a Windows-style stream interface. Also they are supported when
891 capturing a WIM from NTFS or applying a WIM to NTFS.
893 Split WIMs are better supported. You may now apply an image directly
894 from a split WIM, mount an image from a split WIM read-only, or export
895 an image from a split WIM.
897 Using a capture configuration file is now supported (but not fully yet).
899 SHA1 message digests are checked in more places, so we can make sure
900 applied and captured data is correct.
902 Man pages have been updated and consolidated.
905 Fixed segfault when unmounting read-only WIM.
908 Support for joining and splitting WIMs.
909 Also, security data is now preserved by default.
912 Can now build with older gcc and system headers, like on CentOS 5.
915 Fixed bug that made it impossible to overwrite files in read-write
919 Write byte-order mark before WIM XML data. (imagex.exe requires this to
