2 Added experimental support for Windows VSS (Volume Shadow Copy Service).
3 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
4 create and use a temporary VSS snapshot when capturing a WIM image.
6 Implemented setting of Windows-specific XML information, such as
7 architecture, system root, and version details. This information is now
8 automatically set in newly captured WIM images, when appropriate.
10 The progress messages printed by wimlib-imagex while writing WIM files
11 have been slightly tweaked.
13 Progress information for directory tree scans now counts all hard links.
15 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
16 'wiminfo'. This option lets you assign values to elements in a WIM
17 file's XML document by name.
19 The wimlib_get_image_property() and wimlib_set_image_property() API
20 functions now support numerically indexed elements.
22 Fixed a bug where, on Windows, wimlib would change the security
23 descriptor of the target directory of an extraction even when the
24 '--no-acls' option was specified.
27 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
28 some Microsoft software would not correctly recognize data in the
31 Made some small improvements to the compression algorithms:
32 LZX compression ratio was slightly improved.
33 XPRESS compression ratio and speed was slightly improved.
34 LZMS compression speed was slightly improved.
36 Improved handling of WIM XML data. wimlib no longer drops unrecognized
37 elements when exporting images. In addition, two API functions were
38 added for better access to elements in the XML document:
39 wimlib_get_image_property() and wimlib_set_image_property().
41 Added support for (unsafe) in-place compaction of WIM files.
43 Improved performance of image export by reusing metadata resources
44 instead of always rebuilding and recompressing them.
46 Improved performance of wimlib_update_image() by delaying the update to
47 the WIM's XML document until a write is requested.
49 On Windows, the target of an extraction may now be a reparse point
50 (which will be dereferenced).
52 On Windows, wimlib now correctly restores non-Microsoft reparse points.
53 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
55 On Windows, wimlib now has improved performance when archiving files
56 from a filesystem backed by a WIM (a "WIMBoot" setup).
58 Several improvements to System Compression (compact mode) support:
60 wof.sys (or wofadk.sys) is now automatically attached to the
61 target volume if needed.
63 Compact-mode extractions now work correctly with wofadk.sys on
64 older versions of Windows.
66 For compatibility with the Windows bootloader, the requested
67 compression format now is overridden on certain files.
72 This release primarily contains various minor bug fixes and
73 improvements, including:
75 Improved handling of deep directory structures.
77 Fixed a bug where on 32-bit systems, the library could enter an
78 infinite loop if a WIM file was malformed in a specific way.
80 Added a workaround for a case where libntfs-3g may report
81 duplicate streams in an NTFS file.
83 Windows symbolic links and junctions in mounted WIM images are
84 now automatically rewritten to be valid in the mounted location.
86 Reparse point fixes: correctly handle the "ReparseReserved"
87 field, and correctly handle "empty" (data-less) reparse points.
89 On Windows, wimlib now acquires SeManageVolumePrivilege, which
90 is needed to create externally backed files using the
93 Improved validation of filenames.
95 Improved LZMS decompression speed.
97 The configure script now honors alternate pkg-config settings.
99 Links have been updated to point to the new website.
101 In addition, experimental support has been added for compressing
102 extracted files using System Compression on Windows 10. This
103 functionality is available through the new '--compact' option to
104 'wimapply' and 'wimextract' as well as new library flags.
107 Fixed a bug in the LZX decompressor: malicious input data could cause
108 out of bounds writes to memory (since wimlib v1.2.2).
110 The output of the 'wiminfo' command now consolidates various boolean
111 flags (such as "Relative path junction") into a single line.
113 A file can now have both an unnamed data stream ("file contents") and a
114 reparse point stream. Such files can exist as a result of the use of
115 certain Windows features, such as offline storage, including "OneDrive".
116 wimlib will now store and restore both streams on Windows as well as in
117 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
119 On Windows, named data streams of encrypted files are no longer stored
120 twice in WIM archives.
122 On Windows, named data streams are now correctly extracted to existing
123 "readonly" directories. Before, an error would be reported.
125 On Windows, it is now possible to do a "WIMBoot mode" extraction with
126 non-standalone WIMs such as delta WIMs.
128 On Windows, when doing an extraction in "WIMBoot mode", files larger
129 than 4 gigabytes are now never extracted as externally backed. This
130 works around a bug in Microsoft's "WOF" driver.
132 The '--enable-verify-compression' configure option has been removed. If
133 you want to verify a WIM file, use the 'wimverify' program.
135 The way the "file count", "directory count", "total bytes", and "hard
136 link bytes" image statistics (stored in the WIM XML data) is calculated
137 has been slightly changed.
139 In mounted WIM images, the disk usage provided for each file (st_blocks)
140 is now the compressed size rather than the uncompressed size.
142 The performance of the NTFS-3g and Windows capture modes has been
145 On UNIX-like systems, symbolic links whose targets contain the backslash
146 character are now handled correctly (losslessly).
149 Improved the LZX compressor. It is now 15-20% faster than before and
150 provides a slightly better compression ratio.
152 Improved the LZMS compressor. It now provides a compression ratio
153 slightly better than WIMGAPI while still being faster and using slightly
156 The compression chunk size in solid resources, e.g. when capturing or
157 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
158 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
159 better compression ratio and is the same value that WIMGAPI uses. The
160 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
161 lower than WIMGAPI's memory usage, but if it is too much, it is still
162 possible to choose a lower value, e.g. with the '--solid-chunk-size'
163 option to wimlib-imagex.
165 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
166 accept the 'K', 'M', and 'G' suffixes.
168 Files are now sorted by name extension when creating a solid WIM file.
170 Fixed various issues related to capture/apply of EFS-encrypted files on
173 The file list printed by 'wimdir' is now sorted by the platform-specific
174 case sensitivity setting, rather than always case sensitively. This
175 also affects the library function wimlib_iterate_dir_tree().
177 On Windows, some error and warning messages have been improved.
180 The Windows binary distribution no longer contains third party DLLs.
181 These dependencies are instead compiled directly into the libwim DLL.
183 Added more fixes for wimlib on non-x86 architectures such as ARM.
185 Extracting files to a Windows PE in-memory filesystem no longer fails if
186 the target files do not yet exist.
188 Improved the performance of XPRESS compression and LZMS decompression.
190 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
191 It will automatically be faster on newer Intel and AMD processors.
193 Removed the --with-imagex-progname and --enable-more-assertions
197 Fix for very slow export from solid WIM / ESD files.
199 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
201 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
202 may use this to treat some types of errors as non-fatal.
204 The library now permits making in-memory changes to a WIMStruct backed
205 by a read-only WIM file.
207 Fixes for "WIMBoot" extraction mode (Windows only):
209 When not using the WOF driver, extraction no longer fails if the
210 disk containing the WIM file has too many partitions.
212 When matching patterns in [PrepopulateList], all hard links of
213 each file are now considered.
215 The system registry files are now automatically treated as being
216 in [PrepopulateList].
218 Added a hack to try to work around an intermittent bug in
219 Microsoft's WOF (Windows Overlay Filesystem) driver.
222 Made more improvements to the XPRESS, LZX, and LZMS compressors.
224 A number of improvements to the Windows port:
226 Fixes for setting short filenames.
228 Faster "WIMBoot" extraction.
230 Updated and slimmed down the dependent DLLs.
232 ACL inheritence bits are now restored.
234 Mandatory integrity labels are now backed up and restored.
236 Added a workaround for an issue where in rare cases, wimlib could create
237 a compressed data stream that could not be read correctly by Windows
238 after an extraction in "WIMBoot" mode.
241 Added file count progress data for
242 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
243 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
245 Added support for testing file exclusions via the user-provided
248 Some documentation improvements.
250 Made some clarifications to the license text in the COPYING file.
253 Made more improvements to the XPRESS, LZX, and LZMS compressors.
255 The default compression mode for wimcapture is now LZX compression in
256 its default mode, which is the same as '--compress=maximum'.
258 You can now specify an optional integer compression level to the
259 '--compress' option; e.g. '--compress=lzx:75'.
261 Made a minor change to the LZMS compressor and decompressor to fix an
262 incompatibility with the Microsoft implementation. In the unlikely
263 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
264 earlier and a checksum error is reported when extracting files from it
265 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
268 Added 'verify' subcommand to wimlib-imagex.
270 Notable library changes:
272 Custom compressor parameters have been removed from the library
273 in favor of the simpler level-based API.
275 Decompressor parameters have been removed entirely.
277 Library users can now specify a custom file for warning and
278 error messages to be sent to, rather than the default of
281 New progress messages:
282 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
283 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
285 New function: wimlib_verify_wim().
288 Improved compression, decompression, and extraction performance.
290 Improved compatibility with version 3584 WIM / ESD files:
291 - Add support for reading and writing multiple solid blocks per
292 archive, which WIMGAPI/DISM can create when appending an image.
293 - Correctly create solid blocks larger than 4 GiB.
295 'add' commands passed to wimupdate will now replace existing
296 nondirectory files by default. Use the --no-replace option to get the
299 The license for the library now contains an exception that allows using
300 it under the LGPL. See the COPYING file for details.
302 In reparse-point fixup mode (the default for capture), symbolic links
303 and junctions that point outside the tree being captured are no longer
304 excluded from capture.
306 Added support for "WIMBoot" capture and extraction. See the
307 documentation for the new '--wimboot' option to wimcapture and wimapply
308 for more information.
310 On UNIX-like systems, you can now backup and restore device nodes, named
311 pipes, and sockets. In addition, 32-bit user and group IDs are now
314 The way that UNIX data is stored in WIM files has been changed. If you
315 captured any WIMs with the --unix-data option, to upgrade them you'll
316 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
317 re-capture them with --unix-data using this version.
319 wimlib now understands tagged metadata items, such as object IDs, that
320 can be stored in WIM directory entries.
322 Removed the --hardlink and --symlink options to wimapply, since I don't
323 think they are too useful and they got in the way of improving the code.
325 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
327 The 'mkwinpeimg' script now supports writing the ISO image to standard
330 The <ARCH> element in WIM XML data is now exported correctly.
332 On Windows, sparse file attributes are no longer set on extracted files.
333 Oddly enough, this actually saves disk space in some cases.
335 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
336 supported. Mounting WIM images now always requires extended attribute
337 support. Use --without-fuse to disable support for mounting WIM images;
338 this will also disable the need for extended attribute support.
340 Configuring with --enable-ssse3-sha1 now works correctly.
342 The shared library version has been bumped up. The main
343 incompatibilities are:
345 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
346 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
349 - User-provided progress functions are now registered using a
350 separate function, wimlib_register_progress_function(). The
351 'progress_func' argument to many functions no longer exists.
353 - The return value from user-provided progress functions is now
356 - A context argument has been added to the prototype of
357 user-provided progress functions.
359 - 'struct wimlib_capture_config' has been removed. The library
360 now takes the path to the configuration file directly. This
361 affects wimlib_add_image(), wimlib_add_image_multisource(),
362 and wimlib_update_image(). However, a NULL value passed in
363 the argument retains the same meaning.
365 - Removed deprecated functions: some (de)compression functions,
366 wimlib_extract_files(), and wimlib_print_metadata().
368 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
369 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
370 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
372 - Removed some progress messages:
373 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
374 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
375 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
378 - Removed some error codes. Numbering stays the same.
380 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
381 WIMLIB_UNMOUNT_FLAG_FORCE.
383 - WIM paths passed to progress functions now have a leading
387 Case-insensitive comparisons of strings (e.g. filenames) containing
388 UTF-16 codepoints above 32767 are now done correctly.
390 Fixed build failure on Mac OS X.
392 wimunmount now provides the '--new-image' option to cause changes to a
393 read-write mounted image to be committed as a new image rather than as
394 an update of the mounted image. (The corresponding new library flag is
395 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
397 The LZMS ("recovery") compression chunk size, or "dictionary size", may
398 now be up to 1 GiB (1,073,741,824 bytes).
400 The performance of LZX ("maximum") and LZMS ("recovery") compression
401 with large chunk sizes has been slightly improved.
404 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
405 decompressed correctly.
407 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
408 occurred in an unlikely case, and due to validity checks it did not
409 affect successfully created archives.
411 Fixed a minor compatibility issue with the LZMS compressor and
412 decompressor. This is *not* the default compression type and was only
413 introduced in v1.6.0. In the unlikely event that you created an
414 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
415 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
418 Memory usage for LZMS and LZX compression has been decreased.
420 wimextract now allows wildcard characters in paths specified on the
421 command line. Also, the '--strict-wildcards' option has been removed
422 and replaced with the inverse option '--nullglob'. See the
423 documentation for wimextract for more details and changes.
425 The wimlib_extract_files() function is now considered deprecated in
426 favor of wimlib_extract_paths().
428 Fixed more permissions problems when extracting files on Windows.
430 A new '--no-attributes' option has been added to wimapply and
431 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
433 The default chunk size is now set correctly when changing the
434 compression type of a WIM, for example with 'wimoptimize'.
436 The '--metadata' option to wiminfo has been replaced with the
437 '--detailed' option to wimdir.
439 In relevant wimlib-imagex commands, '--solid' may now be used as an
440 alias for '--pack-streams'.
443 Support for extracting and updating the new version 3584 WIMs has been
444 added. These WIMs typically pack many streams ("files") together into a
445 single compressed resource, thereby saving space. This degrades the
446 performance of random access (such as that which occurs on a mounted
447 image), but optimizations have been implemented for extraction. These
448 new WIM files also typically use a new compression format (LZMS), which
449 is similar to LZMA and can offer a better compression ratio than LZX.
450 These new WIM files can be created using `wimcapture' with
451 the '--compress=lzms --pack-streams' options. Note: this new WIM format
452 is used by the Windows 8 web downloader, but important segments of the
453 raw '.esd' files are encrypted, so wimlib will not be able to extract
454 such files until they are first decrypted.
456 wimlib now supports extracting files and directories from a WIM image
457 based on a "listfile" that itself contains the list of paths to extract.
458 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
459 and for the library itself, the new APIs are wimlib_extract_pathlist()
460 and wimlib_extract_paths(). Path globs containing wildcard characters
463 For searching WIM files, wimlib now has configurable case sensitivity.
464 The default on Windows is still case-insensitive and the default on
465 UNIX-like systems is still case-sensitive, but this can be overridden
466 on either platform through flags to wimlib_global_init(). For
467 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
468 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
471 Support for compression chunk sizes greater than the default of 32768
472 bytes has been added. A larger chunk size typically results in a better
473 compression ratio. However, the MS implementation is seemingly not
474 compatible with all chunk sizes, especially for LZX compression, so the
475 defaults remain unchanged, with the exception of the new LZMS-compressed
476 WIMs, which use a larger chunk size by default.
478 The compression/decompression API exported by wimlib has been changed.
479 Now one set of functions handles all supported compression formats.
481 `wimcapture' and `wimappend' will now display the progress of scanning
482 the directory tree to capture, in addition to the progress of writing
483 data to the WIM. The '--verbose' option no longer does anything. The
484 library API change for this is the addition of several members to
485 `struct wimlib_progress_info_scan' available to progress callbacks.
487 `mkwinpeimg' now correctly handles the '--start-script' option when the
488 start script is not in the working directory.
490 Sequential extraction, previously requested by using
491 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
492 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
493 behavior (extract in file order).
496 The new LZX compressor added in v1.5.2 has been improved and is now
497 enabled by default, except when `wimcapture' or `wimappend' is run
498 *without* the '--compress' option, in which case the faster LZX
499 compressor is used (the same as before). This behavior is reasonably
500 consistent with ImageX which actually uses "fast" (XPRESS) compression
501 by default. In those cases, use '--compress=maximum' to explicitly
502 capture a WIM image using the new (slower but better) LZX compressor.
504 The '--compress-slow' option still exists to `wimlib-imagex optimize',
505 but its new behavior is to tweak the new LZX compressor even more to
506 produce an even better compression ratio at the cost of more time spent
509 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
510 which recompresses the WIM file using the specified compression TYPE.
511 The new library API function used for this is
512 wimlib_set_output_compression_type().
514 Added the wimlib_get_xml_data() function to allow library clients to
515 easily retrieve the raw XML data from a WIM file if needed.
517 Fixed a bug that could cause an error code to be incorrectly returned
518 when writing XML data containing a <WINDOWS> element.
520 Mounted WIM images will now correctly show the default file stream even
521 if appears in the alternate data stream entries of the corresponding WIM
525 Added a new experimental LZX compressor which can be enabled by passing
526 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
527 optimize'. (The latter is only applicable if the WIM is already
528 LZX-compressed and the '--recompress' option is also given.) The
529 experimental compressor is much slower but compresses the data slightly
530 more --- currently usually to within a fraction of a percent of the
531 results from WIMGAPI/ImageX.
533 A workaround has been added for compatibility with versions of WinPE
534 that interpret alternate data stream entries in the boot WIM
537 An alignment bug that caused a crash in the LZX decompressor on some
540 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
541 the WIM header when restoring the previous state of a WIM it failed to
544 Added a workaround to avoid an access denied error on Windows when
545 replacing a WIM file that another process has opened.
548 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
549 needed to be handled.
551 A bug in the interpretation of negative IMAGE indices in the
552 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
553 `wimlib-imagex append' has been fixed.
555 A workaround has been added to successfully apply security descriptors
556 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
557 2013.1.13 or earlier.
559 `wimlib-imagex capture' can now accept the '--delta-from' option
563 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
564 to standard output and applying images from standard input, but they are
565 not compatible with Microsoft's software and are not created by default.
566 See the documentation for --pipable flag of `wimlib-imagex capture' for
569 To better support incremental backups, added support for declaring an
570 image as a modified form of another image. See the documentation for
571 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
574 Added supported for "delta" WIMs. See the documentation for the
575 '--delta-from' option of `wimlib-imagex capture'.
577 The library support for managing split WIMs has been changed to support
578 other arrangements, such as delta WIMs, and be easier to use. This
579 change is visible in `wimlib-imagex', which also can now accept the
580 '--ref' option multiple times, and also now supports "delta" WIMs as
583 wimlib now preserves WIM integrity tables by default, even if
584 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
585 behavior of `wimlib-imagex' whenever the WIM being operated on contains
586 an integrity table and the '--check' option is not specified.
588 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
589 (when --compress is not specified). This provides the best compression
590 ratio by default, which is usually what is desired, at a cost of some
593 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
594 is the command as in `wimlib-imagex COMMAND'; for example, it can be
595 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
596 appropriate hard links are created in UNIX installations of
597 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
598 batch files that emulate this behavior are generated.
600 Security descriptors are now extracted correctly on Windows.
602 Fixed archiving DOS names in NTFS-3g capture mode.
604 The extraction code has been rewritten and it will now be easier to
605 support new features on all supported backends (currently Win32, UNIX,
606 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
607 now supported on all backends, not just UNIX.
609 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
610 than the WAIK itself.
612 wimlib_global_init() now, by default, attempts to acquire additional
613 privileges on Windows, so library clients need not do this.
615 This update bumps the shared library version number up to 9, since it is
616 not binary compatibible with previous releases.
619 Fixed bug in `wimlib-imagex export' that made it impossible to export an
620 image from a WIM that is readonly at the filesystem level.
622 Return error code rather than segfaulting when trying to list files from
623 a non-first part of a split WIM.
625 Joining a WIM will now preserve the RP_FIX and READONLY flags.
628 On Windows, paths given to wimlib-imagex are now treated case
631 Improved behavior regarding invalid filenames; in particular, on
632 Windows, wimlib-imagex will, when extracting, now omit (with an option
633 to override this default) filenames differing only in case, or filenames
634 containing characters not valid on Windows.
636 On Windows, wimlib now supports capturing and extracting long paths
637 (longer than the so-called MAX_PATH).
639 On Windows, `wimlib-imagex update' now acquires proper privileges when
640 running as an Administrator.
642 `wimlib-imagex update' will now complain if no image is specified when
643 trying to update a multi-image WIM.
645 `wimlib-imagex update' now supports specifying a single update command
646 directly on the command line using the --command option.
648 wimlib-imagex will now choose different units for progress messages,
649 depending on the amount of data that needs to be processed.
651 `wimlib-imagex append' will now generate a unique WIM image name if no
652 name is specified and the defaulted name already exists in the WIM.
654 wimlib now allows you to create unnamed WIM images, which can then only
655 be referred to by index.
657 wimlib now allows you to explicitly declare you want write access to a
658 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
661 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
664 Progress callbacks have been added to wimlib's wimlib_update_image()
667 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
668 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
671 NTFS-3g capture now only warns about two conditions previously treated
674 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
677 wimlib now correctly detects and returns an error when reading a WIM
678 image with a cyclic directory structure. (Fun fact: such a WIM will
679 crash Microsoft's software.)
682 Added new "extract" and "update" subcommands to wimlib-imagex, along
683 with associated APIs in the library. These commands are intended mainly
684 for Windows use but can be used on UNIX as well.
686 Many documentation improvements.
688 Fixed a bug in the Windows build where relative symbolic links were not
689 captured in reparse-point fixup mode.
691 Fixed a bug in the Windows build where file handles were left open to
692 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
694 Fixed a bug in the Windows build of wimlib-imagex where globbing
695 split-WIM parts could cause the program to crash.
697 Fixed a bug where the creation time of WIM images would be shown instead
698 of the last modification time.
700 With the Windows build it is now possible to restore a WIM containing
701 symbolic links as a non-Administrator; however you will receive warnings
702 about not being able to extract the symbolic links.
705 Capturing a WIM image should now be significantly faster in most cases
706 due to improved use of the operating system's cache and avoiding reading
707 files twice whenever possible.
709 The Windows build should now work on Windows XP.
711 The Windows build now supports capturing and restoring hidden,
712 compressed, sparse, and encrypted files.
714 The Windows build now supports capturing and applying WIM images from
715 filesystems other than NTFS (with some reduced functionality).
717 The Windows build now extracts short names correctly.
719 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
720 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
721 capture' and `wimlib-imagex apply'.
723 The performance of splitting and joining WIMs should be slightly
726 The LZX and XPRESS compression and decompression functions are now
727 exported from the library.
730 Improvements and bugfixes for the Windows build.
732 Added --strict-acls options.
734 Fixed the way that wimlib determines the order of images in the WIM.
737 Since wimlib can now be used on Windows, wimlib's implementation of
738 ImageX has been renamed to wimlib-imagex to avoid confusion with
739 Microsoft's implementation of ImageX, which would have the same file
740 name ("imagex.exe"). If you really don't like this you can pass the
741 --with-imagex-progname option to `configure' to choose a different name,
742 or even simply rename the binary yourself (but the former way will
743 configure the man pages to use the chosen name).
745 Various bugs fixed in the Windows build. Mainly to do with capturing
746 and restoring alternate data streams correctly in weird cases, and
747 requesting the correct privileges when opening files. Also added the
748 --noacls options to wimlib-imagex capture, append, and apply.
750 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
751 dynamically loaded, so this may make the library compatible with Windows
752 XP (however, there may still be other problems).
755 Added experimental support for native Windows builds. Binaries can be
756 downloaded from the SourceForge page.
758 --source-list option added to `imagex capture' and `imagex append'.
760 Better support for different character encodings.
763 Storing UNIX file owners, groups, and modes in WIM images is now
764 possible using `imagex capture' with the --unix-data flag.
766 Minor bug fixes and documentation fixes.
769 NTFS capture: Fixed capturing duplicate reparse points.
771 NTFS capture: Capture first unnamed stream if there are more than one
772 (print warning instead of error).
774 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
777 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
780 Update to work with ntfs-3g version 2013.1.13.
783 Fixed truncating file to shorter but non-zero length on read-write
786 Various code cleanups and minor documentation fixes.
789 LZX and XPRESS decompression have received some additional optimizations
790 and should now be even faster. (Although, they were already pretty
791 fast--- much faster than typical I/O speeds.)
793 Fixed a bug introduced in v1.2.1 that would cause a directory tree
794 containing hard links to be captured incorrectly in some cases.
797 By default, unmounting a read-write mounted WIM with 'imagex unmount
798 --commit' will now change the WIM in-place without needing to write the
799 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
802 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
803 for a response from the daemon servicing the mounted WIM. Instead,
804 every second 'imagex unmount' will check if the daemon is still alive,
805 and keep waiting if so, otherwise terminate with an error.
807 'imagex unmount --commit' on a read-write mounted WIM will now print
808 progress information regarding the writing of new or modified streams
809 the WIM, just like when capturing or appending a WIM.
811 A small change has been made to XPRESS compression and it should improve
812 the compression ratio slightly.
814 A change was made that may improve performance slightly when applying a
815 WIM image to a NTFS volume.
817 Microsoft has managed to introduce even more bugs into their software,
818 and now the WIMs for Windows 8 have incorrect (too low) reference counts
819 for some streams. This is unsafe because such streams can be removed
820 when they are in actuality still referenced in the WIM (perhaps by a
821 different image). wimlib will now work around this problem by fixing
822 the stream reference counts. This is only done when wimlib_delete_image() is
823 called ('imagex delete') or when wimlib_mount_image() is called with
824 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
825 requires reading the metadata for all images in the WIM, so this will
826 make these operations noticably slower on WIMs with multiple images.
828 Various other bugfixes.
831 Appending images to a WIM is now be done by default without re-building
832 the whole WIM. Use the --rebuild flag to get the old behavior (which
833 was to re-build the entire WIM when a new image is appended).
835 A new command `imagex optimize' is now available to manually re-build a
836 WIM that has wasted space due to repeated appends.
838 Progress information has been improved, and now arbitrary callback
839 functions can be used to show the progress of a WIM operation.
841 A possible bug with changing the bootable image of a WIM was fixed.
843 Some advisory locking is now done to prevent two processes from
844 modifying a WIM at the same time (but only in some cases). For example,
845 you cannot mount two images from a WIM read-write at the same time.
847 Some functions have been reorganized:
848 * wimlib_mount() renamed to wimlib_mount_image().
849 * wimlib_unmount() renamed to wimlib_unmount_image().
850 * wimlib_overwrite_xml_and_header() removed as
851 wimlib_overwrite() suffices now.
852 * wimlib_apply_image_to_ntfs_volume() removed as
853 wimlib_extract_image() suffices now.
854 * wimlib_add_image_from_ntfs_volume() removed as
855 * wimlib_add_image() suffices now.
857 Previously, the soname of libwim.so has been 0.0.0, despite many
858 interface changes. The soname is now updated to 1.0.0 and will now be
859 updated each release.
862 Resources will now be compressed using multiple threads by default.
863 (This applies to `imagex capture', `imagex append', and `imagex
866 Some performance improvements in mounted WIMs.
868 More progress information is shown when capturing a WIM.
871 Lots of minor fixes, code cleanups, and some documentation updates.
872 Nothing in particular is really noteworthy.
875 LZX and XPRESS compression improvements.
877 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
878 Link Bytes of the WIM.
881 Fixed bug when capturing NTFS file with multiple named data streams.
883 Internally, we are now using inode structures, even though these don't
884 appear literally in the WIM file. This simplifies some of the code
885 (mainly for WIM mounting) and likely fixed a few problems, although it
889 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
893 Enough changes to call it version 1.0.0!
895 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
896 to a NTFS volume, is now supported.
898 Hard links and symbolic links have much improved support. They are
899 supported for WIM capture, WIM application, and mounted WIMs (you can
900 even make them on read-write mounted WIMs).
902 Alternate data streams are now supported on mounted WIMs through an
903 xattr or a Windows-style stream interface. Also they are supported when
904 capturing a WIM from NTFS or applying a WIM to NTFS.
906 Split WIMs are better supported. You may now apply an image directly
907 from a split WIM, mount an image from a split WIM read-only, or export
908 an image from a split WIM.
910 Using a capture configuration file is now supported (but not fully yet).
912 SHA1 message digests are checked in more places, so we can make sure
913 applied and captured data is correct.
915 Man pages have been updated and consolidated.
918 Fixed segfault when unmounting read-only WIM.
921 Support for joining and splitting WIMs.
922 Also, security data is now preserved by default.
925 Can now build with older gcc and system headers, like on CentOS 5.
928 Fixed bug that made it impossible to overwrite files in read-write
932 Write byte-order mark before WIM XML data. (imagex.exe requires this to
