2 Reduced memory usage when exporting large numbers of WIM images.
4 Made some minor build-related updates. Notably, enabled "silent" make
5 rules; this makes the output cleaner when building from source.
7 Some minor Windows-specific updates:
8 Fixed a bug where duplicate backslashes could be generated in
9 link targets when extracting symbolic links and junctions.
11 Added instructions for building from source on Windows.
13 VSS support is no longer marked "experimental".
15 wimlib now issues an appropriate error message if a known
16 problem with the WindowsApps directory is encountered.
18 wimlib now automatically retries some read requests.
21 Added experimental support for Windows VSS (Volume Shadow Copy Service).
22 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
23 create and use a temporary VSS snapshot when capturing a WIM image.
25 Implemented setting of Windows-specific XML information, such as
26 architecture, system root, and version details. This information is now
27 automatically set in newly captured WIM images, when appropriate.
29 Improved performance of directory tree scans on Windows.
31 On Windows, to improve capture performance, wimlib now sometimes opens
32 files by inode number rather than by path. This is enabled for
33 wimcapture and wimappend, but for now other applications have to opt-in.
35 The progress messages printed by wimlib-imagex while writing WIM files
36 have been slightly tweaked.
38 Progress information for directory tree scans now counts all hard links.
39 Also, on Windows "\\?\" is no longer stripped from the current path.
41 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
42 'wiminfo'. This option lets you assign values to elements in a WIM
43 file's XML document by name.
45 The wimlib_get_image_property() and wimlib_set_image_property() API
46 functions now support numerically indexed elements.
48 Fixed a bug where, on Windows, wimlib would change the security
49 descriptor of the target directory of an extraction even when the
50 '--no-acls' option was specified.
53 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
54 some Microsoft software would not correctly recognize data in the
57 Made some small improvements to the compression algorithms:
58 LZX compression ratio was slightly improved.
59 XPRESS compression ratio and speed was slightly improved.
60 LZMS compression speed was slightly improved.
62 Improved handling of WIM XML data. wimlib no longer drops unrecognized
63 elements when exporting images. In addition, two API functions were
64 added for better access to elements in the XML document:
65 wimlib_get_image_property() and wimlib_set_image_property().
67 Added support for (unsafe) in-place compaction of WIM files.
69 Improved performance of image export by reusing metadata resources
70 instead of always rebuilding and recompressing them.
72 Improved performance of wimlib_update_image() by delaying the update to
73 the WIM's XML document until a write is requested.
75 On Windows, the target of an extraction may now be a reparse point
76 (which will be dereferenced).
78 On Windows, wimlib now correctly restores non-Microsoft reparse points.
79 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
81 On Windows, wimlib now has improved performance when archiving files
82 from a filesystem backed by a WIM (a "WIMBoot" setup).
84 Several improvements to System Compression (compact mode) support:
86 wof.sys (or wofadk.sys) is now automatically attached to the
87 target volume if needed.
89 Compact-mode extractions now work correctly with wofadk.sys on
90 older versions of Windows.
92 For compatibility with the Windows bootloader, the requested
93 compression format now is overridden on certain files.
98 This release primarily contains various minor bug fixes and
99 improvements, including:
101 Improved handling of deep directory structures.
103 Fixed a bug where on 32-bit systems, the library could enter an
104 infinite loop if a WIM file was malformed in a specific way.
106 Added a workaround for a case where libntfs-3g may report
107 duplicate streams in an NTFS file.
109 Windows symbolic links and junctions in mounted WIM images are
110 now automatically rewritten to be valid in the mounted location.
112 Reparse point fixes: correctly handle the "ReparseReserved"
113 field, and correctly handle "empty" (data-less) reparse points.
115 On Windows, wimlib now acquires SeManageVolumePrivilege, which
116 is needed to create externally backed files using the
119 Improved validation of filenames.
121 Improved LZMS decompression speed.
123 The configure script now honors alternate pkg-config settings.
125 Links have been updated to point to the new website.
127 In addition, experimental support has been added for compressing
128 extracted files using System Compression on Windows 10. This
129 functionality is available through the new '--compact' option to
130 'wimapply' and 'wimextract' as well as new library flags.
133 Fixed a bug in the LZX decompressor: malicious input data could cause
134 out of bounds writes to memory (since wimlib v1.2.2).
136 The output of the 'wiminfo' command now consolidates various boolean
137 flags (such as "Relative path junction") into a single line.
139 A file can now have both an unnamed data stream ("file contents") and a
140 reparse point stream. Such files can exist as a result of the use of
141 certain Windows features, such as offline storage, including "OneDrive".
142 wimlib will now store and restore both streams on Windows as well as in
143 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
145 On Windows, named data streams of encrypted files are no longer stored
146 twice in WIM archives.
148 On Windows, named data streams are now correctly extracted to existing
149 "readonly" directories. Before, an error would be reported.
151 On Windows, it is now possible to do a "WIMBoot mode" extraction with
152 non-standalone WIMs such as delta WIMs.
154 On Windows, when doing an extraction in "WIMBoot mode", files larger
155 than 4 gigabytes are now never extracted as externally backed. This
156 works around a bug in Microsoft's "WOF" driver.
158 The '--enable-verify-compression' configure option has been removed. If
159 you want to verify a WIM file, use the 'wimverify' program.
161 The way the "file count", "directory count", "total bytes", and "hard
162 link bytes" image statistics (stored in the WIM XML data) is calculated
163 has been slightly changed.
165 In mounted WIM images, the disk usage provided for each file (st_blocks)
166 is now the compressed size rather than the uncompressed size.
168 The performance of the NTFS-3g and Windows capture modes has been
171 On UNIX-like systems, symbolic links whose targets contain the backslash
172 character are now handled correctly (losslessly).
175 Improved the LZX compressor. It is now 15-20% faster than before and
176 provides a slightly better compression ratio.
178 Improved the LZMS compressor. It now provides a compression ratio
179 slightly better than WIMGAPI while still being faster and using slightly
182 The compression chunk size in solid resources, e.g. when capturing or
183 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
184 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
185 better compression ratio and is the same value that WIMGAPI uses. The
186 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
187 lower than WIMGAPI's memory usage, but if it is too much, it is still
188 possible to choose a lower value, e.g. with the '--solid-chunk-size'
189 option to wimlib-imagex.
191 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
192 accept the 'K', 'M', and 'G' suffixes.
194 Files are now sorted by name extension when creating a solid WIM file.
196 Fixed various issues related to capture/apply of EFS-encrypted files on
199 The file list printed by 'wimdir' is now sorted by the platform-specific
200 case sensitivity setting, rather than always case sensitively. This
201 also affects the library function wimlib_iterate_dir_tree().
203 On Windows, some error and warning messages have been improved.
206 The Windows binary distribution no longer contains third party DLLs.
207 These dependencies are instead compiled directly into the libwim DLL.
209 Added more fixes for wimlib on non-x86 architectures such as ARM.
211 Extracting files to a Windows PE in-memory filesystem no longer fails if
212 the target files do not yet exist.
214 Improved the performance of XPRESS compression and LZMS decompression.
216 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
217 It will automatically be faster on newer Intel and AMD processors.
219 Removed the --with-imagex-progname and --enable-more-assertions
223 Fix for very slow export from solid WIM / ESD files.
225 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
227 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
228 may use this to treat some types of errors as non-fatal.
230 The library now permits making in-memory changes to a WIMStruct backed
231 by a read-only WIM file.
233 Fixes for "WIMBoot" extraction mode (Windows only):
235 When not using the WOF driver, extraction no longer fails if the
236 disk containing the WIM file has too many partitions.
238 When matching patterns in [PrepopulateList], all hard links of
239 each file are now considered.
241 The system registry files are now automatically treated as being
242 in [PrepopulateList].
244 Added a hack to try to work around an intermittent bug in
245 Microsoft's WOF (Windows Overlay Filesystem) driver.
248 Made more improvements to the XPRESS, LZX, and LZMS compressors.
250 A number of improvements to the Windows port:
252 Fixes for setting short filenames.
254 Faster "WIMBoot" extraction.
256 Updated and slimmed down the dependent DLLs.
258 ACL inheritence bits are now restored.
260 Mandatory integrity labels are now backed up and restored.
262 Added a workaround for an issue where in rare cases, wimlib could create
263 a compressed data stream that could not be read correctly by Windows
264 after an extraction in "WIMBoot" mode.
267 Added file count progress data for
268 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
269 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
271 Added support for testing file exclusions via the user-provided
274 Some documentation improvements.
276 Made some clarifications to the license text in the COPYING file.
279 Made more improvements to the XPRESS, LZX, and LZMS compressors.
281 The default compression mode for wimcapture is now LZX compression in
282 its default mode, which is the same as '--compress=maximum'.
284 You can now specify an optional integer compression level to the
285 '--compress' option; e.g. '--compress=lzx:75'.
287 Made a minor change to the LZMS compressor and decompressor to fix an
288 incompatibility with the Microsoft implementation. In the unlikely
289 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
290 earlier and a checksum error is reported when extracting files from it
291 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
294 Added 'verify' subcommand to wimlib-imagex.
296 Notable library changes:
298 Custom compressor parameters have been removed from the library
299 in favor of the simpler level-based API.
301 Decompressor parameters have been removed entirely.
303 Library users can now specify a custom file for warning and
304 error messages to be sent to, rather than the default of
307 New progress messages:
308 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
309 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
311 New function: wimlib_verify_wim().
314 Improved compression, decompression, and extraction performance.
316 Improved compatibility with version 3584 WIM / ESD files:
317 - Add support for reading and writing multiple solid blocks per
318 archive, which WIMGAPI/DISM can create when appending an image.
319 - Correctly create solid blocks larger than 4 GiB.
321 'add' commands passed to wimupdate will now replace existing
322 nondirectory files by default. Use the --no-replace option to get the
325 The license for the library now contains an exception that allows using
326 it under the LGPL. See the COPYING file for details.
328 In reparse-point fixup mode (the default for capture), symbolic links
329 and junctions that point outside the tree being captured are no longer
330 excluded from capture.
332 Added support for "WIMBoot" capture and extraction. See the
333 documentation for the new '--wimboot' option to wimcapture and wimapply
334 for more information.
336 On UNIX-like systems, you can now backup and restore device nodes, named
337 pipes, and sockets. In addition, 32-bit user and group IDs are now
340 The way that UNIX data is stored in WIM files has been changed. If you
341 captured any WIMs with the --unix-data option, to upgrade them you'll
342 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
343 re-capture them with --unix-data using this version.
345 wimlib now understands tagged metadata items, such as object IDs, that
346 can be stored in WIM directory entries.
348 Removed the --hardlink and --symlink options to wimapply, since I don't
349 think they are too useful and they got in the way of improving the code.
351 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
353 The 'mkwinpeimg' script now supports writing the ISO image to standard
356 The <ARCH> element in WIM XML data is now exported correctly.
358 On Windows, sparse file attributes are no longer set on extracted files.
359 Oddly enough, this actually saves disk space in some cases.
361 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
362 supported. Mounting WIM images now always requires extended attribute
363 support. Use --without-fuse to disable support for mounting WIM images;
364 this will also disable the need for extended attribute support.
366 Configuring with --enable-ssse3-sha1 now works correctly.
368 The shared library version has been bumped up. The main
369 incompatibilities are:
371 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
372 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
375 - User-provided progress functions are now registered using a
376 separate function, wimlib_register_progress_function(). The
377 'progress_func' argument to many functions no longer exists.
379 - The return value from user-provided progress functions is now
382 - A context argument has been added to the prototype of
383 user-provided progress functions.
385 - 'struct wimlib_capture_config' has been removed. The library
386 now takes the path to the configuration file directly. This
387 affects wimlib_add_image(), wimlib_add_image_multisource(),
388 and wimlib_update_image(). However, a NULL value passed in
389 the argument retains the same meaning.
391 - Removed deprecated functions: some (de)compression functions,
392 wimlib_extract_files(), and wimlib_print_metadata().
394 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
395 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
396 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
398 - Removed some progress messages:
399 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
400 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
401 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
404 - Removed some error codes. Numbering stays the same.
406 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
407 WIMLIB_UNMOUNT_FLAG_FORCE.
409 - WIM paths passed to progress functions now have a leading
413 Case-insensitive comparisons of strings (e.g. filenames) containing
414 UTF-16 codepoints above 32767 are now done correctly.
416 Fixed build failure on Mac OS X.
418 wimunmount now provides the '--new-image' option to cause changes to a
419 read-write mounted image to be committed as a new image rather than as
420 an update of the mounted image. (The corresponding new library flag is
421 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
423 The LZMS ("recovery") compression chunk size, or "dictionary size", may
424 now be up to 1 GiB (1,073,741,824 bytes).
426 The performance of LZX ("maximum") and LZMS ("recovery") compression
427 with large chunk sizes has been slightly improved.
430 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
431 decompressed correctly.
433 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
434 occurred in an unlikely case, and due to validity checks it did not
435 affect successfully created archives.
437 Fixed a minor compatibility issue with the LZMS compressor and
438 decompressor. This is *not* the default compression type and was only
439 introduced in v1.6.0. In the unlikely event that you created an
440 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
441 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
444 Memory usage for LZMS and LZX compression has been decreased.
446 wimextract now allows wildcard characters in paths specified on the
447 command line. Also, the '--strict-wildcards' option has been removed
448 and replaced with the inverse option '--nullglob'. See the
449 documentation for wimextract for more details and changes.
451 The wimlib_extract_files() function is now considered deprecated in
452 favor of wimlib_extract_paths().
454 Fixed more permissions problems when extracting files on Windows.
456 A new '--no-attributes' option has been added to wimapply and
457 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
459 The default chunk size is now set correctly when changing the
460 compression type of a WIM, for example with 'wimoptimize'.
462 The '--metadata' option to wiminfo has been replaced with the
463 '--detailed' option to wimdir.
465 In relevant wimlib-imagex commands, '--solid' may now be used as an
466 alias for '--pack-streams'.
469 Support for extracting and updating the new version 3584 WIMs has been
470 added. These WIMs typically pack many streams ("files") together into a
471 single compressed resource, thereby saving space. This degrades the
472 performance of random access (such as that which occurs on a mounted
473 image), but optimizations have been implemented for extraction. These
474 new WIM files also typically use a new compression format (LZMS), which
475 is similar to LZMA and can offer a better compression ratio than LZX.
476 These new WIM files can be created using `wimcapture' with
477 the '--compress=lzms --pack-streams' options. Note: this new WIM format
478 is used by the Windows 8 web downloader, but important segments of the
479 raw '.esd' files are encrypted, so wimlib will not be able to extract
480 such files until they are first decrypted.
482 wimlib now supports extracting files and directories from a WIM image
483 based on a "listfile" that itself contains the list of paths to extract.
484 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
485 and for the library itself, the new APIs are wimlib_extract_pathlist()
486 and wimlib_extract_paths(). Path globs containing wildcard characters
489 For searching WIM files, wimlib now has configurable case sensitivity.
490 The default on Windows is still case-insensitive and the default on
491 UNIX-like systems is still case-sensitive, but this can be overridden
492 on either platform through flags to wimlib_global_init(). For
493 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
494 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
497 Support for compression chunk sizes greater than the default of 32768
498 bytes has been added. A larger chunk size typically results in a better
499 compression ratio. However, the MS implementation is seemingly not
500 compatible with all chunk sizes, especially for LZX compression, so the
501 defaults remain unchanged, with the exception of the new LZMS-compressed
502 WIMs, which use a larger chunk size by default.
504 The compression/decompression API exported by wimlib has been changed.
505 Now one set of functions handles all supported compression formats.
507 `wimcapture' and `wimappend' will now display the progress of scanning
508 the directory tree to capture, in addition to the progress of writing
509 data to the WIM. The '--verbose' option no longer does anything. The
510 library API change for this is the addition of several members to
511 `struct wimlib_progress_info_scan' available to progress callbacks.
513 `mkwinpeimg' now correctly handles the '--start-script' option when the
514 start script is not in the working directory.
516 Sequential extraction, previously requested by using
517 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
518 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
519 behavior (extract in file order).
522 The new LZX compressor added in v1.5.2 has been improved and is now
523 enabled by default, except when `wimcapture' or `wimappend' is run
524 *without* the '--compress' option, in which case the faster LZX
525 compressor is used (the same as before). This behavior is reasonably
526 consistent with ImageX which actually uses "fast" (XPRESS) compression
527 by default. In those cases, use '--compress=maximum' to explicitly
528 capture a WIM image using the new (slower but better) LZX compressor.
530 The '--compress-slow' option still exists to `wimlib-imagex optimize',
531 but its new behavior is to tweak the new LZX compressor even more to
532 produce an even better compression ratio at the cost of more time spent
535 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
536 which recompresses the WIM file using the specified compression TYPE.
537 The new library API function used for this is
538 wimlib_set_output_compression_type().
540 Added the wimlib_get_xml_data() function to allow library clients to
541 easily retrieve the raw XML data from a WIM file if needed.
543 Fixed a bug that could cause an error code to be incorrectly returned
544 when writing XML data containing a <WINDOWS> element.
546 Mounted WIM images will now correctly show the default file stream even
547 if appears in the alternate data stream entries of the corresponding WIM
551 Added a new experimental LZX compressor which can be enabled by passing
552 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
553 optimize'. (The latter is only applicable if the WIM is already
554 LZX-compressed and the '--recompress' option is also given.) The
555 experimental compressor is much slower but compresses the data slightly
556 more --- currently usually to within a fraction of a percent of the
557 results from WIMGAPI/ImageX.
559 A workaround has been added for compatibility with versions of WinPE
560 that interpret alternate data stream entries in the boot WIM
563 An alignment bug that caused a crash in the LZX decompressor on some
566 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
567 the WIM header when restoring the previous state of a WIM it failed to
570 Added a workaround to avoid an access denied error on Windows when
571 replacing a WIM file that another process has opened.
574 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
575 needed to be handled.
577 A bug in the interpretation of negative IMAGE indices in the
578 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
579 `wimlib-imagex append' has been fixed.
581 A workaround has been added to successfully apply security descriptors
582 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
583 2013.1.13 or earlier.
585 `wimlib-imagex capture' can now accept the '--delta-from' option
589 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
590 to standard output and applying images from standard input, but they are
591 not compatible with Microsoft's software and are not created by default.
592 See the documentation for --pipable flag of `wimlib-imagex capture' for
595 To better support incremental backups, added support for declaring an
596 image as a modified form of another image. See the documentation for
597 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
600 Added supported for "delta" WIMs. See the documentation for the
601 '--delta-from' option of `wimlib-imagex capture'.
603 The library support for managing split WIMs has been changed to support
604 other arrangements, such as delta WIMs, and be easier to use. This
605 change is visible in `wimlib-imagex', which also can now accept the
606 '--ref' option multiple times, and also now supports "delta" WIMs as
609 wimlib now preserves WIM integrity tables by default, even if
610 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
611 behavior of `wimlib-imagex' whenever the WIM being operated on contains
612 an integrity table and the '--check' option is not specified.
614 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
615 (when --compress is not specified). This provides the best compression
616 ratio by default, which is usually what is desired, at a cost of some
619 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
620 is the command as in `wimlib-imagex COMMAND'; for example, it can be
621 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
622 appropriate hard links are created in UNIX installations of
623 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
624 batch files that emulate this behavior are generated.
626 Security descriptors are now extracted correctly on Windows.
628 Fixed archiving DOS names in NTFS-3g capture mode.
630 The extraction code has been rewritten and it will now be easier to
631 support new features on all supported backends (currently Win32, UNIX,
632 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
633 now supported on all backends, not just UNIX.
635 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
636 than the WAIK itself.
638 wimlib_global_init() now, by default, attempts to acquire additional
639 privileges on Windows, so library clients need not do this.
641 This update bumps the shared library version number up to 9, since it is
642 not binary compatibible with previous releases.
645 Fixed bug in `wimlib-imagex export' that made it impossible to export an
646 image from a WIM that is readonly at the filesystem level.
648 Return error code rather than segfaulting when trying to list files from
649 a non-first part of a split WIM.
651 Joining a WIM will now preserve the RP_FIX and READONLY flags.
654 On Windows, paths given to wimlib-imagex are now treated case
657 Improved behavior regarding invalid filenames; in particular, on
658 Windows, wimlib-imagex will, when extracting, now omit (with an option
659 to override this default) filenames differing only in case, or filenames
660 containing characters not valid on Windows.
662 On Windows, wimlib now supports capturing and extracting long paths
663 (longer than the so-called MAX_PATH).
665 On Windows, `wimlib-imagex update' now acquires proper privileges when
666 running as an Administrator.
668 `wimlib-imagex update' will now complain if no image is specified when
669 trying to update a multi-image WIM.
671 `wimlib-imagex update' now supports specifying a single update command
672 directly on the command line using the --command option.
674 wimlib-imagex will now choose different units for progress messages,
675 depending on the amount of data that needs to be processed.
677 `wimlib-imagex append' will now generate a unique WIM image name if no
678 name is specified and the defaulted name already exists in the WIM.
680 wimlib now allows you to create unnamed WIM images, which can then only
681 be referred to by index.
683 wimlib now allows you to explicitly declare you want write access to a
684 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
687 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
690 Progress callbacks have been added to wimlib's wimlib_update_image()
693 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
694 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
697 NTFS-3g capture now only warns about two conditions previously treated
700 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
703 wimlib now correctly detects and returns an error when reading a WIM
704 image with a cyclic directory structure. (Fun fact: such a WIM will
705 crash Microsoft's software.)
708 Added new "extract" and "update" subcommands to wimlib-imagex, along
709 with associated APIs in the library. These commands are intended mainly
710 for Windows use but can be used on UNIX as well.
712 Many documentation improvements.
714 Fixed a bug in the Windows build where relative symbolic links were not
715 captured in reparse-point fixup mode.
717 Fixed a bug in the Windows build where file handles were left open to
718 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
720 Fixed a bug in the Windows build of wimlib-imagex where globbing
721 split-WIM parts could cause the program to crash.
723 Fixed a bug where the creation time of WIM images would be shown instead
724 of the last modification time.
726 With the Windows build it is now possible to restore a WIM containing
727 symbolic links as a non-Administrator; however you will receive warnings
728 about not being able to extract the symbolic links.
731 Capturing a WIM image should now be significantly faster in most cases
732 due to improved use of the operating system's cache and avoiding reading
733 files twice whenever possible.
735 The Windows build should now work on Windows XP.
737 The Windows build now supports capturing and restoring hidden,
738 compressed, sparse, and encrypted files.
740 The Windows build now supports capturing and applying WIM images from
741 filesystems other than NTFS (with some reduced functionality).
743 The Windows build now extracts short names correctly.
745 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
746 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
747 capture' and `wimlib-imagex apply'.
749 The performance of splitting and joining WIMs should be slightly
752 The LZX and XPRESS compression and decompression functions are now
753 exported from the library.
756 Improvements and bugfixes for the Windows build.
758 Added --strict-acls options.
760 Fixed the way that wimlib determines the order of images in the WIM.
763 Since wimlib can now be used on Windows, wimlib's implementation of
764 ImageX has been renamed to wimlib-imagex to avoid confusion with
765 Microsoft's implementation of ImageX, which would have the same file
766 name ("imagex.exe"). If you really don't like this you can pass the
767 --with-imagex-progname option to `configure' to choose a different name,
768 or even simply rename the binary yourself (but the former way will
769 configure the man pages to use the chosen name).
771 Various bugs fixed in the Windows build. Mainly to do with capturing
772 and restoring alternate data streams correctly in weird cases, and
773 requesting the correct privileges when opening files. Also added the
774 --noacls options to wimlib-imagex capture, append, and apply.
776 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
777 dynamically loaded, so this may make the library compatible with Windows
778 XP (however, there may still be other problems).
781 Added experimental support for native Windows builds. Binaries can be
782 downloaded from the SourceForge page.
784 --source-list option added to `imagex capture' and `imagex append'.
786 Better support for different character encodings.
789 Storing UNIX file owners, groups, and modes in WIM images is now
790 possible using `imagex capture' with the --unix-data flag.
792 Minor bug fixes and documentation fixes.
795 NTFS capture: Fixed capturing duplicate reparse points.
797 NTFS capture: Capture first unnamed stream if there are more than one
798 (print warning instead of error).
800 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
803 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
806 Update to work with ntfs-3g version 2013.1.13.
809 Fixed truncating file to shorter but non-zero length on read-write
812 Various code cleanups and minor documentation fixes.
815 LZX and XPRESS decompression have received some additional optimizations
816 and should now be even faster. (Although, they were already pretty
817 fast--- much faster than typical I/O speeds.)
819 Fixed a bug introduced in v1.2.1 that would cause a directory tree
820 containing hard links to be captured incorrectly in some cases.
823 By default, unmounting a read-write mounted WIM with 'imagex unmount
824 --commit' will now change the WIM in-place without needing to write the
825 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
828 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
829 for a response from the daemon servicing the mounted WIM. Instead,
830 every second 'imagex unmount' will check if the daemon is still alive,
831 and keep waiting if so, otherwise terminate with an error.
833 'imagex unmount --commit' on a read-write mounted WIM will now print
834 progress information regarding the writing of new or modified streams
835 the WIM, just like when capturing or appending a WIM.
837 A small change has been made to XPRESS compression and it should improve
838 the compression ratio slightly.
840 A change was made that may improve performance slightly when applying a
841 WIM image to a NTFS volume.
843 Microsoft has managed to introduce even more bugs into their software,
844 and now the WIMs for Windows 8 have incorrect (too low) reference counts
845 for some streams. This is unsafe because such streams can be removed
846 when they are in actuality still referenced in the WIM (perhaps by a
847 different image). wimlib will now work around this problem by fixing
848 the stream reference counts. This is only done when wimlib_delete_image() is
849 called ('imagex delete') or when wimlib_mount_image() is called with
850 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
851 requires reading the metadata for all images in the WIM, so this will
852 make these operations noticably slower on WIMs with multiple images.
854 Various other bugfixes.
857 Appending images to a WIM is now be done by default without re-building
858 the whole WIM. Use the --rebuild flag to get the old behavior (which
859 was to re-build the entire WIM when a new image is appended).
861 A new command `imagex optimize' is now available to manually re-build a
862 WIM that has wasted space due to repeated appends.
864 Progress information has been improved, and now arbitrary callback
865 functions can be used to show the progress of a WIM operation.
867 A possible bug with changing the bootable image of a WIM was fixed.
869 Some advisory locking is now done to prevent two processes from
870 modifying a WIM at the same time (but only in some cases). For example,
871 you cannot mount two images from a WIM read-write at the same time.
873 Some functions have been reorganized:
874 * wimlib_mount() renamed to wimlib_mount_image().
875 * wimlib_unmount() renamed to wimlib_unmount_image().
876 * wimlib_overwrite_xml_and_header() removed as
877 wimlib_overwrite() suffices now.
878 * wimlib_apply_image_to_ntfs_volume() removed as
879 wimlib_extract_image() suffices now.
880 * wimlib_add_image_from_ntfs_volume() removed as
881 * wimlib_add_image() suffices now.
883 Previously, the soname of libwim.so has been 0.0.0, despite many
884 interface changes. The soname is now updated to 1.0.0 and will now be
885 updated each release.
888 Resources will now be compressed using multiple threads by default.
889 (This applies to `imagex capture', `imagex append', and `imagex
892 Some performance improvements in mounted WIMs.
894 More progress information is shown when capturing a WIM.
897 Lots of minor fixes, code cleanups, and some documentation updates.
898 Nothing in particular is really noteworthy.
901 LZX and XPRESS compression improvements.
903 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
904 Link Bytes of the WIM.
907 Fixed bug when capturing NTFS file with multiple named data streams.
909 Internally, we are now using inode structures, even though these don't
910 appear literally in the WIM file. This simplifies some of the code
911 (mainly for WIM mounting) and likely fixed a few problems, although it
915 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
919 Enough changes to call it version 1.0.0!
921 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
922 to a NTFS volume, is now supported.
924 Hard links and symbolic links have much improved support. They are
925 supported for WIM capture, WIM application, and mounted WIMs (you can
926 even make them on read-write mounted WIMs).
928 Alternate data streams are now supported on mounted WIMs through an
929 xattr or a Windows-style stream interface. Also they are supported when
930 capturing a WIM from NTFS or applying a WIM to NTFS.
932 Split WIMs are better supported. You may now apply an image directly
933 from a split WIM, mount an image from a split WIM read-only, or export
934 an image from a split WIM.
936 Using a capture configuration file is now supported (but not fully yet).
938 SHA1 message digests are checked in more places, so we can make sure
939 applied and captured data is correct.
941 Man pages have been updated and consolidated.
944 Fixed segfault when unmounting read-only WIM.
947 Support for joining and splitting WIMs.
948 Also, security data is now preserved by default.
951 Can now build with older gcc and system headers, like on CentOS 5.
954 Fixed bug that made it impossible to overwrite files in read-write
958 Write byte-order mark before WIM XML data. (imagex.exe requires this to
