2 Updated 'mkwinpeimg' to work correctly on images that have a "windows"
3 (lower case) directory rather than a "Windows" (upper case) directory.
5 On Windows, improved the way in which files deduplicated with Windows'
6 Data Deduplication feature are captured.
8 Fixed configuring with --enable-ssse3-sha1 from release tarball
9 (the file nasm_lt.sh was missing).
11 The development files needed to link with wimlib using Visual Studio are
12 now included in the Windows release archives.
14 wimlib.h can now be included by Visual Studio without errors.
16 The example programs can now be compiled in C++ mode, and they also now
20 The LZX compression ratio has been slightly improved. The default mode,
21 LZX level 50, is now almost as good as the old LZX level 100, while
22 being nearly the same speed as before.
24 Decompression performance has been slightly improved.
26 Filenames are now always listed in NTFS collation order.
28 On UNIX-like systems, wimlib can now process Windows filenames that are
29 not valid Unicode due to the presence of unpaired surrogates.
31 On UNIX-like systems, wimlib now always assumes UTF-8 encoding with the
32 addition of surrogate codepoints. Consequently, the environmental
33 variable WIMLIB_IMAGEX_USE_UTF8 and the flag
34 WIMLIB_INIT_FLAG_ASSUME_UTF8 no longer have any effect.
36 wimlib no longer depends on iconv.
38 Reduced memory usage slightly.
40 When a WIM image is applied in NTFS-3G mode, security descriptors are
41 now created in NTFS v3.0 format when supported by the volume.
43 Workarounds for bugs in libntfs-3g version 2013.1.13 and earlier have
44 been removed. Users are advised to upgrade to a later version of
47 On Windows, wimlib now supports case-sensitive filename extraction when
48 supported by the underlying operating system and filesystem (operating
49 system support requires a registry setting).
52 On UNIX, wimlib can now overwrite readonly files when extracting.
54 On Windows, fixed a bug where wimlib could leave a null DACL (a.k.a. "no
55 NTFS permissions") set on some existing directories after extraction.
57 On Windows, when applying a WIM image in "WIMBoot mode" when the WOF
58 driver is not loaded, wimlib can now correctly register a new WIM file
59 with the target volume when the target volume previously had had WIM
62 Added a new testing program.
64 Clarified the main license text and updated public domain dedications
65 for certain files to be more thorough.
68 Object IDs are now saved and restored on Windows and in NTFS-3G mode.
70 Reduced memory usage when exporting large numbers of WIM images.
72 Non UTF-8 locales are now detected correctly.
74 Addressed compiler warnings and enabled "silent" make rules by default.
76 Windows-specific updates:
77 Fixed a bug where duplicate backslashes could be generated in
78 link targets when extracting symbolic links and junctions.
80 Fixed a bug where the .cmd shortcuts for wimlib-imagex wouldn't
81 work if their full path contained a space.
83 Fixed bugs related to scanning SMB filesystems.
85 Added warning message about known issue with WindowsApps folder.
87 Added instructions for building from source on Windows.
89 VSS support is no longer marked "experimental".
91 Added missing license file for libdivsufsort-lite.
94 Added experimental support for Windows VSS (Volume Shadow Copy Service).
95 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
96 create and use a temporary VSS snapshot when capturing a WIM image.
98 Implemented setting of Windows-specific XML information, such as
99 architecture, system root, and version details. This information is now
100 automatically set in newly captured WIM images, when appropriate.
102 Improved performance of directory tree scans on Windows.
104 On Windows, to improve capture performance, wimlib now sometimes opens
105 files by inode number rather than by path. This is enabled for
106 wimcapture and wimappend, but for now other applications have to opt-in.
108 The progress messages printed by wimlib-imagex while writing WIM files
109 have been slightly tweaked.
111 Progress information for directory tree scans now counts all hard links.
112 Also, on Windows "\\?\" is no longer stripped from the current path.
114 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
115 'wiminfo'. This option lets you assign values to elements in a WIM
116 file's XML document by name.
118 The wimlib_get_image_property() and wimlib_set_image_property() API
119 functions now support numerically indexed elements.
121 Fixed a bug where, on Windows, wimlib would change the security
122 descriptor of the target directory of an extraction even when the
123 '--no-acls' option was specified.
126 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
127 some Microsoft software would not correctly recognize data in the
128 resulting filesystem.
130 Made some small improvements to the compression algorithms:
131 LZX compression ratio was slightly improved.
132 XPRESS compression ratio and speed was slightly improved.
133 LZMS compression speed was slightly improved.
135 Improved handling of WIM XML data. wimlib no longer drops unrecognized
136 elements when exporting images. In addition, two API functions were
137 added for better access to elements in the XML document:
138 wimlib_get_image_property() and wimlib_set_image_property().
140 Added support for (unsafe) in-place compaction of WIM files.
142 Improved performance of image export by reusing metadata resources
143 instead of always rebuilding and recompressing them.
145 Improved performance of wimlib_update_image() by delaying the update to
146 the WIM's XML document until a write is requested.
148 On Windows, the target of an extraction may now be a reparse point
149 (which will be dereferenced).
151 On Windows, wimlib now correctly restores non-Microsoft reparse points.
152 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
154 On Windows, wimlib now has improved performance when archiving files
155 from a filesystem backed by a WIM (a "WIMBoot" setup).
157 Several improvements to System Compression (compact mode) support:
159 wof.sys (or wofadk.sys) is now automatically attached to the
160 target volume if needed.
162 Compact-mode extractions now work correctly with wofadk.sys on
163 older versions of Windows.
165 For compatibility with the Windows bootloader, the requested
166 compression format now is overridden on certain files.
168 Other minor bugfixes.
171 This release primarily contains various minor bug fixes and
172 improvements, including:
174 Improved handling of deep directory structures.
176 Fixed a bug where on 32-bit systems, the library could enter an
177 infinite loop if a WIM file was malformed in a specific way.
179 Added a workaround for a case where libntfs-3g may report
180 duplicate streams in an NTFS file.
182 Windows symbolic links and junctions in mounted WIM images are
183 now automatically rewritten to be valid in the mounted location.
185 Reparse point fixes: correctly handle the "ReparseReserved"
186 field, and correctly handle "empty" (data-less) reparse points.
188 On Windows, wimlib now acquires SeManageVolumePrivilege, which
189 is needed to create externally backed files using the
192 Improved validation of filenames.
194 Improved LZMS decompression speed.
196 The configure script now honors alternate pkg-config settings.
198 Links have been updated to point to the new website.
200 In addition, experimental support has been added for compressing
201 extracted files using System Compression on Windows 10. This
202 functionality is available through the new '--compact' option to
203 'wimapply' and 'wimextract' as well as new library flags.
206 Fixed a bug in the LZX decompressor: malicious input data could cause
207 out of bounds writes to memory (since wimlib v1.2.2).
209 The output of the 'wiminfo' command now consolidates various boolean
210 flags (such as "Relative path junction") into a single line.
212 A file can now have both an unnamed data stream ("file contents") and a
213 reparse point stream. Such files can exist as a result of the use of
214 certain Windows features, such as offline storage, including "OneDrive".
215 wimlib will now store and restore both streams on Windows as well as in
216 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
218 On Windows, named data streams of encrypted files are no longer stored
219 twice in WIM archives.
221 On Windows, named data streams are now correctly extracted to existing
222 "readonly" directories. Before, an error would be reported.
224 On Windows, it is now possible to do a "WIMBoot mode" extraction with
225 non-standalone WIMs such as delta WIMs.
227 On Windows, when doing an extraction in "WIMBoot mode", files larger
228 than 4 gigabytes are now never extracted as externally backed. This
229 works around a bug in Microsoft's "WOF" driver.
231 The '--enable-verify-compression' configure option has been removed. If
232 you want to verify a WIM file, use the 'wimverify' program.
234 The way the "file count", "directory count", "total bytes", and "hard
235 link bytes" image statistics (stored in the WIM XML data) is calculated
236 has been slightly changed.
238 In mounted WIM images, the disk usage provided for each file (st_blocks)
239 is now the compressed size rather than the uncompressed size.
241 The performance of the NTFS-3g and Windows capture modes has been
244 On UNIX-like systems, symbolic links whose targets contain the backslash
245 character are now handled correctly (losslessly).
248 Improved the LZX compressor. It is now 15-20% faster than before and
249 provides a slightly better compression ratio.
251 Improved the LZMS compressor. It now provides a compression ratio
252 slightly better than WIMGAPI while still being faster and using slightly
255 The compression chunk size in solid resources, e.g. when capturing or
256 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
257 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
258 better compression ratio and is the same value that WIMGAPI uses. The
259 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
260 lower than WIMGAPI's memory usage, but if it is too much, it is still
261 possible to choose a lower value, e.g. with the '--solid-chunk-size'
262 option to wimlib-imagex.
264 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
265 accept the 'K', 'M', and 'G' suffixes.
267 Files are now sorted by name extension when creating a solid WIM file.
269 Fixed various issues related to capture/apply of EFS-encrypted files on
272 The file list printed by 'wimdir' is now sorted by the platform-specific
273 case sensitivity setting, rather than always case sensitively. This
274 also affects the library function wimlib_iterate_dir_tree().
276 On Windows, some error and warning messages have been improved.
279 The Windows binary distribution no longer contains third party DLLs.
280 These dependencies are instead compiled directly into the libwim DLL.
282 Added more fixes for wimlib on non-x86 architectures such as ARM.
284 Extracting files to a Windows PE in-memory filesystem no longer fails if
285 the target files do not yet exist.
287 Improved the performance of XPRESS compression and LZMS decompression.
289 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
290 It will automatically be faster on newer Intel and AMD processors.
292 Removed the --with-imagex-progname and --enable-more-assertions
296 Fix for very slow export from solid WIM / ESD files.
298 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
300 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
301 may use this to treat some types of errors as non-fatal.
303 The library now permits making in-memory changes to a WIMStruct backed
304 by a read-only WIM file.
306 Fixes for "WIMBoot" extraction mode (Windows only):
308 When not using the WOF driver, extraction no longer fails if the
309 disk containing the WIM file has too many partitions.
311 When matching patterns in [PrepopulateList], all hard links of
312 each file are now considered.
314 The system registry files are now automatically treated as being
315 in [PrepopulateList].
317 Added a hack to try to work around an intermittent bug in
318 Microsoft's WOF (Windows Overlay Filesystem) driver.
321 Made more improvements to the XPRESS, LZX, and LZMS compressors.
323 A number of improvements to the Windows port:
325 Fixes for setting short filenames.
327 Faster "WIMBoot" extraction.
329 Updated and slimmed down the dependent DLLs.
331 ACL inheritence bits are now restored.
333 Mandatory integrity labels are now backed up and restored.
335 Added a workaround for an issue where in rare cases, wimlib could create
336 a compressed data stream that could not be read correctly by Windows
337 after an extraction in "WIMBoot" mode.
340 Added file count progress data for
341 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
342 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
344 Added support for testing file exclusions via the user-provided
347 Some documentation improvements.
349 Made some clarifications to the license text in the COPYING file.
352 Made more improvements to the XPRESS, LZX, and LZMS compressors.
354 The default compression mode for wimcapture is now LZX compression in
355 its default mode, which is the same as '--compress=maximum'.
357 You can now specify an optional integer compression level to the
358 '--compress' option; e.g. '--compress=lzx:75'.
360 Made a minor change to the LZMS compressor and decompressor to fix an
361 incompatibility with the Microsoft implementation. In the unlikely
362 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
363 earlier and a checksum error is reported when extracting files from it
364 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
367 Added 'verify' subcommand to wimlib-imagex.
369 Notable library changes:
371 Custom compressor parameters have been removed from the library
372 in favor of the simpler level-based API.
374 Decompressor parameters have been removed entirely.
376 Library users can now specify a custom file for warning and
377 error messages to be sent to, rather than the default of
380 New progress messages:
381 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
382 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
384 New function: wimlib_verify_wim().
387 Improved compression, decompression, and extraction performance.
389 Improved compatibility with version 3584 WIM / ESD files:
390 - Add support for reading and writing multiple solid blocks per
391 archive, which WIMGAPI/DISM can create when appending an image.
392 - Correctly create solid blocks larger than 4 GiB.
394 'add' commands passed to wimupdate will now replace existing
395 nondirectory files by default. Use the --no-replace option to get the
398 The license for the library now contains an exception that allows using
399 it under the LGPL. See the COPYING file for details.
401 In reparse-point fixup mode (the default for capture), symbolic links
402 and junctions that point outside the tree being captured are no longer
403 excluded from capture.
405 Added support for "WIMBoot" capture and extraction. See the
406 documentation for the new '--wimboot' option to wimcapture and wimapply
407 for more information.
409 On UNIX-like systems, you can now backup and restore device nodes, named
410 pipes, and sockets. In addition, 32-bit user and group IDs are now
413 The way that UNIX data is stored in WIM files has been changed. If you
414 captured any WIMs with the --unix-data option, to upgrade them you'll
415 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
416 re-capture them with --unix-data using this version.
418 wimlib now understands tagged metadata items, such as object IDs, that
419 can be stored in WIM directory entries.
421 Removed the --hardlink and --symlink options to wimapply, since I don't
422 think they are too useful and they got in the way of improving the code.
424 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
426 The 'mkwinpeimg' script now supports writing the ISO image to standard
429 The <ARCH> element in WIM XML data is now exported correctly.
431 On Windows, sparse file attributes are no longer set on extracted files.
432 Oddly enough, this actually saves disk space in some cases.
434 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
435 supported. Mounting WIM images now always requires extended attribute
436 support. Use --without-fuse to disable support for mounting WIM images;
437 this will also disable the need for extended attribute support.
439 Configuring with --enable-ssse3-sha1 now works correctly.
441 The shared library version has been bumped up. The main
442 incompatibilities are:
444 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
445 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
448 - User-provided progress functions are now registered using a
449 separate function, wimlib_register_progress_function(). The
450 'progress_func' argument to many functions no longer exists.
452 - The return value from user-provided progress functions is now
455 - A context argument has been added to the prototype of
456 user-provided progress functions.
458 - 'struct wimlib_capture_config' has been removed. The library
459 now takes the path to the configuration file directly. This
460 affects wimlib_add_image(), wimlib_add_image_multisource(),
461 and wimlib_update_image(). However, a NULL value passed in
462 the argument retains the same meaning.
464 - Removed deprecated functions: some (de)compression functions,
465 wimlib_extract_files(), and wimlib_print_metadata().
467 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
468 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
469 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
471 - Removed some progress messages:
472 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
473 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
474 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
477 - Removed some error codes. Numbering stays the same.
479 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
480 WIMLIB_UNMOUNT_FLAG_FORCE.
482 - WIM paths passed to progress functions now have a leading
486 Case-insensitive comparisons of strings (e.g. filenames) containing
487 UTF-16 codepoints above 32767 are now done correctly.
489 Fixed build failure on Mac OS X.
491 wimunmount now provides the '--new-image' option to cause changes to a
492 read-write mounted image to be committed as a new image rather than as
493 an update of the mounted image. (The corresponding new library flag is
494 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
496 The LZMS ("recovery") compression chunk size, or "dictionary size", may
497 now be up to 1 GiB (1,073,741,824 bytes).
499 The performance of LZX ("maximum") and LZMS ("recovery") compression
500 with large chunk sizes has been slightly improved.
503 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
504 decompressed correctly.
506 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
507 occurred in an unlikely case, and due to validity checks it did not
508 affect successfully created archives.
510 Fixed a minor compatibility issue with the LZMS compressor and
511 decompressor. This is *not* the default compression type and was only
512 introduced in v1.6.0. In the unlikely event that you created an
513 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
514 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
517 Memory usage for LZMS and LZX compression has been decreased.
519 wimextract now allows wildcard characters in paths specified on the
520 command line. Also, the '--strict-wildcards' option has been removed
521 and replaced with the inverse option '--nullglob'. See the
522 documentation for wimextract for more details and changes.
524 The wimlib_extract_files() function is now considered deprecated in
525 favor of wimlib_extract_paths().
527 Fixed more permissions problems when extracting files on Windows.
529 A new '--no-attributes' option has been added to wimapply and
530 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
532 The default chunk size is now set correctly when changing the
533 compression type of a WIM, for example with 'wimoptimize'.
535 The '--metadata' option to wiminfo has been replaced with the
536 '--detailed' option to wimdir.
538 In relevant wimlib-imagex commands, '--solid' may now be used as an
539 alias for '--pack-streams'.
542 Support for extracting and updating the new version 3584 WIMs has been
543 added. These WIMs typically pack many streams ("files") together into a
544 single compressed resource, thereby saving space. This degrades the
545 performance of random access (such as that which occurs on a mounted
546 image), but optimizations have been implemented for extraction. These
547 new WIM files also typically use a new compression format (LZMS), which
548 is similar to LZMA and can offer a better compression ratio than LZX.
549 These new WIM files can be created using `wimcapture' with
550 the '--compress=lzms --pack-streams' options. Note: this new WIM format
551 is used by the Windows 8 web downloader, but important segments of the
552 raw '.esd' files are encrypted, so wimlib will not be able to extract
553 such files until they are first decrypted.
555 wimlib now supports extracting files and directories from a WIM image
556 based on a "listfile" that itself contains the list of paths to extract.
557 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
558 and for the library itself, the new APIs are wimlib_extract_pathlist()
559 and wimlib_extract_paths(). Path globs containing wildcard characters
562 For searching WIM files, wimlib now has configurable case sensitivity.
563 The default on Windows is still case-insensitive and the default on
564 UNIX-like systems is still case-sensitive, but this can be overridden
565 on either platform through flags to wimlib_global_init(). For
566 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
567 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
570 Support for compression chunk sizes greater than the default of 32768
571 bytes has been added. A larger chunk size typically results in a better
572 compression ratio. However, the MS implementation is seemingly not
573 compatible with all chunk sizes, especially for LZX compression, so the
574 defaults remain unchanged, with the exception of the new LZMS-compressed
575 WIMs, which use a larger chunk size by default.
577 The compression/decompression API exported by wimlib has been changed.
578 Now one set of functions handles all supported compression formats.
580 `wimcapture' and `wimappend' will now display the progress of scanning
581 the directory tree to capture, in addition to the progress of writing
582 data to the WIM. The '--verbose' option no longer does anything. The
583 library API change for this is the addition of several members to
584 `struct wimlib_progress_info_scan' available to progress callbacks.
586 `mkwinpeimg' now correctly handles the '--start-script' option when the
587 start script is not in the working directory.
589 Sequential extraction, previously requested by using
590 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
591 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
592 behavior (extract in file order).
595 The new LZX compressor added in v1.5.2 has been improved and is now
596 enabled by default, except when `wimcapture' or `wimappend' is run
597 *without* the '--compress' option, in which case the faster LZX
598 compressor is used (the same as before). This behavior is reasonably
599 consistent with ImageX which actually uses "fast" (XPRESS) compression
600 by default. In those cases, use '--compress=maximum' to explicitly
601 capture a WIM image using the new (slower but better) LZX compressor.
603 The '--compress-slow' option still exists to `wimlib-imagex optimize',
604 but its new behavior is to tweak the new LZX compressor even more to
605 produce an even better compression ratio at the cost of more time spent
608 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
609 which recompresses the WIM file using the specified compression TYPE.
610 The new library API function used for this is
611 wimlib_set_output_compression_type().
613 Added the wimlib_get_xml_data() function to allow library clients to
614 easily retrieve the raw XML data from a WIM file if needed.
616 Fixed a bug that could cause an error code to be incorrectly returned
617 when writing XML data containing a <WINDOWS> element.
619 Mounted WIM images will now correctly show the default file stream even
620 if appears in the alternate data stream entries of the corresponding WIM
624 Added a new experimental LZX compressor which can be enabled by passing
625 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
626 optimize'. (The latter is only applicable if the WIM is already
627 LZX-compressed and the '--recompress' option is also given.) The
628 experimental compressor is much slower but compresses the data slightly
629 more --- currently usually to within a fraction of a percent of the
630 results from WIMGAPI/ImageX.
632 A workaround has been added for compatibility with versions of WinPE
633 that interpret alternate data stream entries in the boot WIM
636 An alignment bug that caused a crash in the LZX decompressor on some
639 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
640 the WIM header when restoring the previous state of a WIM it failed to
643 Added a workaround to avoid an access denied error on Windows when
644 replacing a WIM file that another process has opened.
647 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
648 needed to be handled.
650 A bug in the interpretation of negative IMAGE indices in the
651 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
652 `wimlib-imagex append' has been fixed.
654 A workaround has been added to successfully apply security descriptors
655 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
656 2013.1.13 or earlier.
658 `wimlib-imagex capture' can now accept the '--delta-from' option
662 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
663 to standard output and applying images from standard input, but they are
664 not compatible with Microsoft's software and are not created by default.
665 See the documentation for --pipable flag of `wimlib-imagex capture' for
668 To better support incremental backups, added support for declaring an
669 image as a modified form of another image. See the documentation for
670 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
673 Added supported for "delta" WIMs. See the documentation for the
674 '--delta-from' option of `wimlib-imagex capture'.
676 The library support for managing split WIMs has been changed to support
677 other arrangements, such as delta WIMs, and be easier to use. This
678 change is visible in `wimlib-imagex', which also can now accept the
679 '--ref' option multiple times, and also now supports "delta" WIMs as
682 wimlib now preserves WIM integrity tables by default, even if
683 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
684 behavior of `wimlib-imagex' whenever the WIM being operated on contains
685 an integrity table and the '--check' option is not specified.
687 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
688 (when --compress is not specified). This provides the best compression
689 ratio by default, which is usually what is desired, at a cost of some
692 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
693 is the command as in `wimlib-imagex COMMAND'; for example, it can be
694 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
695 appropriate hard links are created in UNIX installations of
696 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
697 batch files that emulate this behavior are generated.
699 Security descriptors are now extracted correctly on Windows.
701 Fixed archiving DOS names in NTFS-3g capture mode.
703 The extraction code has been rewritten and it will now be easier to
704 support new features on all supported backends (currently Win32, UNIX,
705 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
706 now supported on all backends, not just UNIX.
708 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
709 than the WAIK itself.
711 wimlib_global_init() now, by default, attempts to acquire additional
712 privileges on Windows, so library clients need not do this.
714 This update bumps the shared library version number up to 9, since it is
715 not binary compatibible with previous releases.
718 Fixed bug in `wimlib-imagex export' that made it impossible to export an
719 image from a WIM that is readonly at the filesystem level.
721 Return error code rather than segfaulting when trying to list files from
722 a non-first part of a split WIM.
724 Joining a WIM will now preserve the RP_FIX and READONLY flags.
727 On Windows, paths given to wimlib-imagex are now treated case
730 Improved behavior regarding invalid filenames; in particular, on
731 Windows, wimlib-imagex will, when extracting, now omit (with an option
732 to override this default) filenames differing only in case, or filenames
733 containing characters not valid on Windows.
735 On Windows, wimlib now supports capturing and extracting long paths
736 (longer than the so-called MAX_PATH).
738 On Windows, `wimlib-imagex update' now acquires proper privileges when
739 running as an Administrator.
741 `wimlib-imagex update' will now complain if no image is specified when
742 trying to update a multi-image WIM.
744 `wimlib-imagex update' now supports specifying a single update command
745 directly on the command line using the --command option.
747 wimlib-imagex will now choose different units for progress messages,
748 depending on the amount of data that needs to be processed.
750 `wimlib-imagex append' will now generate a unique WIM image name if no
751 name is specified and the defaulted name already exists in the WIM.
753 wimlib now allows you to create unnamed WIM images, which can then only
754 be referred to by index.
756 wimlib now allows you to explicitly declare you want write access to a
757 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
760 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
763 Progress callbacks have been added to wimlib's wimlib_update_image()
766 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
767 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
770 NTFS-3g capture now only warns about two conditions previously treated
773 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
776 wimlib now correctly detects and returns an error when reading a WIM
777 image with a cyclic directory structure. (Fun fact: such a WIM will
778 crash Microsoft's software.)
781 Added new "extract" and "update" subcommands to wimlib-imagex, along
782 with associated APIs in the library. These commands are intended mainly
783 for Windows use but can be used on UNIX as well.
785 Many documentation improvements.
787 Fixed a bug in the Windows build where relative symbolic links were not
788 captured in reparse-point fixup mode.
790 Fixed a bug in the Windows build where file handles were left open to
791 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
793 Fixed a bug in the Windows build of wimlib-imagex where globbing
794 split-WIM parts could cause the program to crash.
796 Fixed a bug where the creation time of WIM images would be shown instead
797 of the last modification time.
799 With the Windows build it is now possible to restore a WIM containing
800 symbolic links as a non-Administrator; however you will receive warnings
801 about not being able to extract the symbolic links.
804 Capturing a WIM image should now be significantly faster in most cases
805 due to improved use of the operating system's cache and avoiding reading
806 files twice whenever possible.
808 The Windows build should now work on Windows XP.
810 The Windows build now supports capturing and restoring hidden,
811 compressed, sparse, and encrypted files.
813 The Windows build now supports capturing and applying WIM images from
814 filesystems other than NTFS (with some reduced functionality).
816 The Windows build now extracts short names correctly.
818 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
819 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
820 capture' and `wimlib-imagex apply'.
822 The performance of splitting and joining WIMs should be slightly
825 The LZX and XPRESS compression and decompression functions are now
826 exported from the library.
829 Improvements and bugfixes for the Windows build.
831 Added --strict-acls options.
833 Fixed the way that wimlib determines the order of images in the WIM.
836 Since wimlib can now be used on Windows, wimlib's implementation of
837 ImageX has been renamed to wimlib-imagex to avoid confusion with
838 Microsoft's implementation of ImageX, which would have the same file
839 name ("imagex.exe"). If you really don't like this you can pass the
840 --with-imagex-progname option to `configure' to choose a different name,
841 or even simply rename the binary yourself (but the former way will
842 configure the man pages to use the chosen name).
844 Various bugs fixed in the Windows build. Mainly to do with capturing
845 and restoring alternate data streams correctly in weird cases, and
846 requesting the correct privileges when opening files. Also added the
847 --noacls options to wimlib-imagex capture, append, and apply.
849 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
850 dynamically loaded, so this may make the library compatible with Windows
851 XP (however, there may still be other problems).
854 Added experimental support for native Windows builds. Binaries can be
855 downloaded from the SourceForge page.
857 --source-list option added to `imagex capture' and `imagex append'.
859 Better support for different character encodings.
862 Storing UNIX file owners, groups, and modes in WIM images is now
863 possible using `imagex capture' with the --unix-data flag.
865 Minor bug fixes and documentation fixes.
868 NTFS capture: Fixed capturing duplicate reparse points.
870 NTFS capture: Capture first unnamed stream if there are more than one
871 (print warning instead of error).
873 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
876 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
879 Update to work with ntfs-3g version 2013.1.13.
882 Fixed truncating file to shorter but non-zero length on read-write
885 Various code cleanups and minor documentation fixes.
888 LZX and XPRESS decompression have received some additional optimizations
889 and should now be even faster. (Although, they were already pretty
890 fast--- much faster than typical I/O speeds.)
892 Fixed a bug introduced in v1.2.1 that would cause a directory tree
893 containing hard links to be captured incorrectly in some cases.
896 By default, unmounting a read-write mounted WIM with 'imagex unmount
897 --commit' will now change the WIM in-place without needing to write the
898 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
901 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
902 for a response from the daemon servicing the mounted WIM. Instead,
903 every second 'imagex unmount' will check if the daemon is still alive,
904 and keep waiting if so, otherwise terminate with an error.
906 'imagex unmount --commit' on a read-write mounted WIM will now print
907 progress information regarding the writing of new or modified streams
908 the WIM, just like when capturing or appending a WIM.
910 A small change has been made to XPRESS compression and it should improve
911 the compression ratio slightly.
913 A change was made that may improve performance slightly when applying a
914 WIM image to a NTFS volume.
916 Microsoft has managed to introduce even more bugs into their software,
917 and now the WIMs for Windows 8 have incorrect (too low) reference counts
918 for some streams. This is unsafe because such streams can be removed
919 when they are in actuality still referenced in the WIM (perhaps by a
920 different image). wimlib will now work around this problem by fixing
921 the stream reference counts. This is only done when wimlib_delete_image() is
922 called ('imagex delete') or when wimlib_mount_image() is called with
923 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
924 requires reading the metadata for all images in the WIM, so this will
925 make these operations noticably slower on WIMs with multiple images.
927 Various other bugfixes.
930 Appending images to a WIM is now be done by default without re-building
931 the whole WIM. Use the --rebuild flag to get the old behavior (which
932 was to re-build the entire WIM when a new image is appended).
934 A new command `imagex optimize' is now available to manually re-build a
935 WIM that has wasted space due to repeated appends.
937 Progress information has been improved, and now arbitrary callback
938 functions can be used to show the progress of a WIM operation.
940 A possible bug with changing the bootable image of a WIM was fixed.
942 Some advisory locking is now done to prevent two processes from
943 modifying a WIM at the same time (but only in some cases). For example,
944 you cannot mount two images from a WIM read-write at the same time.
946 Some functions have been reorganized:
947 * wimlib_mount() renamed to wimlib_mount_image().
948 * wimlib_unmount() renamed to wimlib_unmount_image().
949 * wimlib_overwrite_xml_and_header() removed as
950 wimlib_overwrite() suffices now.
951 * wimlib_apply_image_to_ntfs_volume() removed as
952 wimlib_extract_image() suffices now.
953 * wimlib_add_image_from_ntfs_volume() removed as
954 * wimlib_add_image() suffices now.
956 Previously, the soname of libwim.so has been 0.0.0, despite many
957 interface changes. The soname is now updated to 1.0.0 and will now be
958 updated each release.
961 Resources will now be compressed using multiple threads by default.
962 (This applies to `imagex capture', `imagex append', and `imagex
965 Some performance improvements in mounted WIMs.
967 More progress information is shown when capturing a WIM.
970 Lots of minor fixes, code cleanups, and some documentation updates.
971 Nothing in particular is really noteworthy.
974 LZX and XPRESS compression improvements.
976 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
977 Link Bytes of the WIM.
980 Fixed bug when capturing NTFS file with multiple named data streams.
982 Internally, we are now using inode structures, even though these don't
983 appear literally in the WIM file. This simplifies some of the code
984 (mainly for WIM mounting) and likely fixed a few problems, although it
988 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
992 Enough changes to call it version 1.0.0!
994 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
995 to a NTFS volume, is now supported.
997 Hard links and symbolic links have much improved support. They are
998 supported for WIM capture, WIM application, and mounted WIMs (you can
999 even make them on read-write mounted WIMs).
1001 Alternate data streams are now supported on mounted WIMs through an
1002 xattr or a Windows-style stream interface. Also they are supported when
1003 capturing a WIM from NTFS or applying a WIM to NTFS.
1005 Split WIMs are better supported. You may now apply an image directly
1006 from a split WIM, mount an image from a split WIM read-only, or export
1007 an image from a split WIM.
1009 Using a capture configuration file is now supported (but not fully yet).
1011 SHA1 message digests are checked in more places, so we can make sure
1012 applied and captured data is correct.
1014 Man pages have been updated and consolidated.
1017 Fixed segfault when unmounting read-only WIM.
1020 Support for joining and splitting WIMs.
1021 Also, security data is now preserved by default.
1024 Can now build with older gcc and system headers, like on CentOS 5.
1027 Fixed bug that made it impossible to overwrite files in read-write
1031 Write byte-order mark before WIM XML data. (imagex.exe requires this to
