2 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
3 some Microsoft software would not correctly recognize data in the
6 Made some small improvements to the compression algorithms:
7 LZX compression ratio was slightly improved.
8 XPRESS compression ratio and speed was slightly improved.
9 LZMS compression speed was slightly improved.
11 Improved handling of WIM XML data. wimlib no longer drops unrecognized
12 elements when exporting images. In addition, two API functions were
13 added for better access to elements in the XML document:
14 wimlib_get_image_property() and wimlib_set_image_property().
16 Added support for (unsafe) in-place compaction of WIM files.
18 Improved performance of image export by reusing metadata resources
19 instead of always rebuilding and recompressing them.
21 Improved performance of wimlib_update_image() by delaying the update to
22 the WIM's XML document until a write is requested.
24 On Windows, the target of an extraction may now be a reparse point.
26 Several improvements to System Compression (compact mode) support:
28 wof.sys (or wofadk.sys) is now automatically attached to the
29 target volume if needed.
31 Compact-mode extractions now work correctly with wofadk.sys on
32 older versions of Windows.
34 For compatibility with the Windows bootloader, the requested
35 compression format now is overridden on certain files.
38 This release primarily contains various minor bug fixes and
39 improvements, including:
41 Improved handling of deep directory structures.
43 Fixed a bug where on 32-bit systems, the library could enter an
44 infinite loop if a WIM file was malformed in a specific way.
46 Added a workaround for a case where libntfs-3g may report
47 duplicate streams in an NTFS file.
49 Windows symbolic links and junctions in mounted WIM images are
50 now automatically rewritten to be valid in the mounted location.
52 Reparse point fixes: correctly handle the "ReparseReserved"
53 field, and correctly handle "empty" (data-less) reparse points.
55 On Windows, wimlib now acquires SeManageVolumePrivilege, which
56 is needed to create externally backed files using the
59 Improved validation of filenames.
61 Improved LZMS decompression speed.
63 The configure script now honors alternate pkg-config settings.
65 Links have been updated to point to the new website.
67 In addition, experimental support has been added for compressing
68 extracted files using System Compression on Windows 10. This
69 functionality is available through the new '--compact' option to
70 'wimapply' and 'wimextract' as well as new library flags.
73 Fixed a bug in the LZX decompressor: malicious input data could cause
74 out of bounds writes to memory (since wimlib v1.2.2).
76 The output of the 'wiminfo' command now consolidates various boolean
77 flags (such as "Relative path junction") into a single line.
79 A file can now have both an unnamed data stream ("file contents") and a
80 reparse point stream. Such files can exist as a result of the use of
81 certain Windows features, such as offline storage, including "OneDrive".
82 wimlib will now store and restore both streams on Windows as well as in
83 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
85 On Windows, named data streams of encrypted files are no longer stored
86 twice in WIM archives.
88 On Windows, named data streams are now correctly extracted to existing
89 "readonly" directories. Before, an error would be reported.
91 On Windows, it is now possible to do a "WIMBoot mode" extraction with
92 non-standalone WIMs such as delta WIMs.
94 On Windows, when doing an extraction in "WIMBoot mode", files larger
95 than 4 gigabytes are now never extracted as externally backed. This
96 works around a bug in Microsoft's "WOF" driver.
98 The '--enable-verify-compression' configure option has been removed. If
99 you want to verify a WIM file, use the 'wimverify' program.
101 The way the "file count", "directory count", "total bytes", and "hard
102 link bytes" image statistics (stored in the WIM XML data) is calculated
103 has been slightly changed.
105 In mounted WIM images, the disk usage provided for each file (st_blocks)
106 is now the compressed size rather than the uncompressed size.
108 The performance of the NTFS-3g and Windows capture modes has been
111 On UNIX-like systems, symbolic links whose targets contain the backslash
112 character are now handled correctly (losslessly).
115 Improved the LZX compressor. It is now 15-20% faster than before and
116 provides a slightly better compression ratio.
118 Improved the LZMS compressor. It now provides a compression ratio
119 slightly better than WIMGAPI while still being faster and using slightly
122 The compression chunk size in solid resources, e.g. when capturing or
123 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
124 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
125 better compression ratio and is the same value that WIMGAPI uses. The
126 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
127 lower than WIMGAPI's memory usage, but if it is too much, it is still
128 possible to choose a lower value, e.g. with the '--solid-chunk-size'
129 option to wimlib-imagex.
131 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
132 accept the 'K', 'M', and 'G' suffixes.
134 Files are now sorted by name extension when creating a solid WIM file.
136 Fixed various issues related to capture/apply of EFS-encrypted files on
139 The file list printed by 'wimdir' is now sorted by the platform-specific
140 case sensitivity setting, rather than always case sensitively. This
141 also affects the library function wimlib_iterate_dir_tree().
143 On Windows, some error and warning messages have been improved.
146 The Windows binary distribution no longer contains third party DLLs.
147 These dependencies are instead compiled directly into the libwim DLL.
149 Added more fixes for wimlib on non-x86 architectures such as ARM.
151 Extracting files to a Windows PE in-memory filesystem no longer fails if
152 the target files do not yet exist.
154 Improved the performance of XPRESS compression and LZMS decompression.
156 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
157 It will automatically be faster on newer Intel and AMD processors.
159 Removed the --with-imagex-progname and --enable-more-assertions
163 Fix for very slow export from solid WIM / ESD files.
165 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
167 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
168 may use this to treat some types of errors as non-fatal.
170 The library now permits making in-memory changes to a WIMStruct backed
171 by a read-only WIM file.
173 Fixes for "WIMBoot" extraction mode (Windows only):
175 When not using the WOF driver, extraction no longer fails if the
176 disk containing the WIM file has too many partitions.
178 When matching patterns in [PrepopulateList], all hard links of
179 each file are now considered.
181 The system registry files are now automatically treated as being
182 in [PrepopulateList].
184 Added a hack to try to work around an intermittent bug in
185 Microsoft's WOF (Windows Overlay Filesystem) driver.
188 Made more improvements to the XPRESS, LZX, and LZMS compressors.
190 A number of improvements to the Windows port:
192 Fixes for setting short filenames.
194 Faster "WIMBoot" extraction.
196 Updated and slimmed down the dependent DLLs.
198 ACL inheritence bits are now restored.
200 Mandatory integrity labels are now backed up and restored.
202 Added a workaround for an issue where in rare cases, wimlib could create
203 a compressed data stream that could not be read correctly by Windows
204 after an extraction in "WIMBoot" mode.
207 Added file count progress data for
208 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
209 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
211 Added support for testing file exclusions via the user-provided
214 Some documentation improvements.
216 Made some clarifications to the license text in the COPYING file.
219 Made more improvements to the XPRESS, LZX, and LZMS compressors.
221 The default compression mode for wimcapture is now LZX compression in
222 its default mode, which is the same as '--compress=maximum'.
224 You can now specify an optional integer compression level to the
225 '--compress' option; e.g. '--compress=lzx:75'.
227 Made a minor change to the LZMS compressor and decompressor to fix an
228 incompatibility with the Microsoft implementation. In the unlikely
229 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
230 earlier and a checksum error is reported when extracting files from it
231 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
234 Added 'verify' subcommand to wimlib-imagex.
236 Notable library changes:
238 Custom compressor parameters have been removed from the library
239 in favor of the simpler level-based API.
241 Decompressor parameters have been removed entirely.
243 Library users can now specify a custom file for warning and
244 error messages to be sent to, rather than the default of
247 New progress messages:
248 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
249 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
251 New function: wimlib_verify_wim().
254 Improved compression, decompression, and extraction performance.
256 Improved compatibility with version 3584 WIM / ESD files:
257 - Add support for reading and writing multiple solid blocks per
258 archive, which WIMGAPI/DISM can create when appending an image.
259 - Correctly create solid blocks larger than 4 GiB.
261 'add' commands passed to wimupdate will now replace existing
262 nondirectory files by default. Use the --no-replace option to get the
265 The license for the library now contains an exception that allows using
266 it under the LGPL. See the COPYING file for details.
268 In reparse-point fixup mode (the default for capture), symbolic links
269 and junctions that point outside the tree being captured are no longer
270 excluded from capture.
272 Added support for "WIMBoot" capture and extraction. See the
273 documentation for the new '--wimboot' option to wimcapture and wimapply
274 for more information.
276 On UNIX-like systems, you can now backup and restore device nodes, named
277 pipes, and sockets. In addition, 32-bit user and group IDs are now
280 The way that UNIX data is stored in WIM files has been changed. If you
281 captured any WIMs with the --unix-data option, to upgrade them you'll
282 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
283 re-capture them with --unix-data using this version.
285 wimlib now understands tagged metadata items, such as object IDs, that
286 can be stored in WIM directory entries.
288 Removed the --hardlink and --symlink options to wimapply, since I don't
289 think they are too useful and they got in the way of improving the code.
291 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
293 The 'mkwinpeimg' script now supports writing the ISO image to standard
296 The <ARCH> element in WIM XML data is now exported correctly.
298 On Windows, sparse file attributes are no longer set on extracted files.
299 Oddly enough, this actually saves disk space in some cases.
301 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
302 supported. Mounting WIM images now always requires extended attribute
303 support. Use --without-fuse to disable support for mounting WIM images;
304 this will also disable the need for extended attribute support.
306 Configuring with --enable-ssse3-sha1 now works correctly.
308 The shared library version has been bumped up. The main
309 incompatibilities are:
311 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
312 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
315 - User-provided progress functions are now registered using a
316 separate function, wimlib_register_progress_function(). The
317 'progress_func' argument to many functions no longer exists.
319 - The return value from user-provided progress functions is now
322 - A context argument has been added to the prototype of
323 user-provided progress functions.
325 - 'struct wimlib_capture_config' has been removed. The library
326 now takes the path to the configuration file directly. This
327 affects wimlib_add_image(), wimlib_add_image_multisource(),
328 and wimlib_update_image(). However, a NULL value passed in
329 the argument retains the same meaning.
331 - Removed deprecated functions: some (de)compression functions,
332 wimlib_extract_files(), and wimlib_print_metadata().
334 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
335 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
336 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
338 - Removed some progress messages:
339 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
340 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
341 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
344 - Removed some error codes. Numbering stays the same.
346 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
347 WIMLIB_UNMOUNT_FLAG_FORCE.
349 - WIM paths passed to progress functions now have a leading
353 Case-insensitive comparisons of strings (e.g. filenames) containing
354 UTF-16 codepoints above 32767 are now done correctly.
356 Fixed build failure on Mac OS X.
358 wimunmount now provides the '--new-image' option to cause changes to a
359 read-write mounted image to be committed as a new image rather than as
360 an update of the mounted image. (The corresponding new library flag is
361 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
363 The LZMS ("recovery") compression chunk size, or "dictionary size", may
364 now be up to 1 GiB (1,073,741,824 bytes).
366 The performance of LZX ("maximum") and LZMS ("recovery") compression
367 with large chunk sizes has been slightly improved.
370 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
371 decompressed correctly.
373 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
374 occurred in an unlikely case, and due to validity checks it did not
375 affect successfully created archives.
377 Fixed a minor compatibility issue with the LZMS compressor and
378 decompressor. This is *not* the default compression type and was only
379 introduced in v1.6.0. In the unlikely event that you created an
380 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
381 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
384 Memory usage for LZMS and LZX compression has been decreased.
386 wimextract now allows wildcard characters in paths specified on the
387 command line. Also, the '--strict-wildcards' option has been removed
388 and replaced with the inverse option '--nullglob'. See the
389 documentation for wimextract for more details and changes.
391 The wimlib_extract_files() function is now considered deprecated in
392 favor of wimlib_extract_paths().
394 Fixed more permissions problems when extracting files on Windows.
396 A new '--no-attributes' option has been added to wimapply and
397 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
399 The default chunk size is now set correctly when changing the
400 compression type of a WIM, for example with 'wimoptimize'.
402 The '--metadata' option to wiminfo has been replaced with the
403 '--detailed' option to wimdir.
405 In relevant wimlib-imagex commands, '--solid' may now be used as an
406 alias for '--pack-streams'.
409 Support for extracting and updating the new version 3584 WIMs has been
410 added. These WIMs typically pack many streams ("files") together into a
411 single compressed resource, thereby saving space. This degrades the
412 performance of random access (such as that which occurs on a mounted
413 image), but optimizations have been implemented for extraction. These
414 new WIM files also typically use a new compression format (LZMS), which
415 is similar to LZMA and can offer a better compression ratio than LZX.
416 These new WIM files can be created using `wimcapture' with
417 the '--compress=lzms --pack-streams' options. Note: this new WIM format
418 is used by the Windows 8 web downloader, but important segments of the
419 raw '.esd' files are encrypted, so wimlib will not be able to extract
420 such files until they are first decrypted.
422 wimlib now supports extracting files and directories from a WIM image
423 based on a "listfile" that itself contains the list of paths to extract.
424 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
425 and for the library itself, the new APIs are wimlib_extract_pathlist()
426 and wimlib_extract_paths(). Path globs containing wildcard characters
429 For searching WIM files, wimlib now has configurable case sensitivity.
430 The default on Windows is still case-insensitive and the default on
431 UNIX-like systems is still case-sensitive, but this can be overridden
432 on either platform through flags to wimlib_global_init(). For
433 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
434 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
437 Support for compression chunk sizes greater than the default of 32768
438 bytes has been added. A larger chunk size typically results in a better
439 compression ratio. However, the MS implementation is seemingly not
440 compatible with all chunk sizes, especially for LZX compression, so the
441 defaults remain unchanged, with the exception of the new LZMS-compressed
442 WIMs, which use a larger chunk size by default.
444 The compression/decompression API exported by wimlib has been changed.
445 Now one set of functions handles all supported compression formats.
447 `wimcapture' and `wimappend' will now display the progress of scanning
448 the directory tree to capture, in addition to the progress of writing
449 data to the WIM. The '--verbose' option no longer does anything. The
450 library API change for this is the addition of several members to
451 `struct wimlib_progress_info_scan' available to progress callbacks.
453 `mkwinpeimg' now correctly handles the '--start-script' option when the
454 start script is not in the working directory.
456 Sequential extraction, previously requested by using
457 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
458 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
459 behavior (extract in file order).
462 The new LZX compressor added in v1.5.2 has been improved and is now
463 enabled by default, except when `wimcapture' or `wimappend' is run
464 *without* the '--compress' option, in which case the faster LZX
465 compressor is used (the same as before). This behavior is reasonably
466 consistent with ImageX which actually uses "fast" (XPRESS) compression
467 by default. In those cases, use '--compress=maximum' to explicitly
468 capture a WIM image using the new (slower but better) LZX compressor.
470 The '--compress-slow' option still exists to `wimlib-imagex optimize',
471 but its new behavior is to tweak the new LZX compressor even more to
472 produce an even better compression ratio at the cost of more time spent
475 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
476 which recompresses the WIM file using the specified compression TYPE.
477 The new library API function used for this is
478 wimlib_set_output_compression_type().
480 Added the wimlib_get_xml_data() function to allow library clients to
481 easily retrieve the raw XML data from a WIM file if needed.
483 Fixed a bug that could cause an error code to be incorrectly returned
484 when writing XML data containing a <WINDOWS> element.
486 Mounted WIM images will now correctly show the default file stream even
487 if appears in the alternate data stream entries of the corresponding WIM
491 Added a new experimental LZX compressor which can be enabled by passing
492 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
493 optimize'. (The latter is only applicable if the WIM is already
494 LZX-compressed and the '--recompress' option is also given.) The
495 experimental compressor is much slower but compresses the data slightly
496 more --- currently usually to within a fraction of a percent of the
497 results from WIMGAPI/ImageX.
499 A workaround has been added for compatibility with versions of WinPE
500 that interpret alternate data stream entries in the boot WIM
503 An alignment bug that caused a crash in the LZX decompressor on some
506 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
507 the WIM header when restoring the previous state of a WIM it failed to
510 Added a workaround to avoid an access denied error on Windows when
511 replacing a WIM file that another process has opened.
514 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
515 needed to be handled.
517 A bug in the interpretation of negative IMAGE indices in the
518 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
519 `wimlib-imagex append' has been fixed.
521 A workaround has been added to successfully apply security descriptors
522 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
523 2013.1.13 or earlier.
525 `wimlib-imagex capture' can now accept the '--delta-from' option
529 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
530 to standard output and applying images from standard input, but they are
531 not compatible with Microsoft's software and are not created by default.
532 See the documentation for --pipable flag of `wimlib-imagex capture' for
535 To better support incremental backups, added support for declaring an
536 image as a modified form of another image. See the documentation for
537 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
540 Added supported for "delta" WIMs. See the documentation for the
541 '--delta-from' option of `wimlib-imagex capture'.
543 The library support for managing split WIMs has been changed to support
544 other arrangements, such as delta WIMs, and be easier to use. This
545 change is visible in `wimlib-imagex', which also can now accept the
546 '--ref' option multiple times, and also now supports "delta" WIMs as
549 wimlib now preserves WIM integrity tables by default, even if
550 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
551 behavior of `wimlib-imagex' whenever the WIM being operated on contains
552 an integrity table and the '--check' option is not specified.
554 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
555 (when --compress is not specified). This provides the best compression
556 ratio by default, which is usually what is desired, at a cost of some
559 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
560 is the command as in `wimlib-imagex COMMAND'; for example, it can be
561 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
562 appropriate hard links are created in UNIX installations of
563 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
564 batch files that emulate this behavior are generated.
566 Security descriptors are now extracted correctly on Windows.
568 Fixed archiving DOS names in NTFS-3g capture mode.
570 The extraction code has been rewritten and it will now be easier to
571 support new features on all supported backends (currently Win32, UNIX,
572 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
573 now supported on all backends, not just UNIX.
575 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
576 than the WAIK itself.
578 wimlib_global_init() now, by default, attempts to acquire additional
579 privileges on Windows, so library clients need not do this.
581 This update bumps the shared library version number up to 9, since it is
582 not binary compatibible with previous releases.
585 Fixed bug in `wimlib-imagex export' that made it impossible to export an
586 image from a WIM that is readonly at the filesystem level.
588 Return error code rather than segfaulting when trying to list files from
589 a non-first part of a split WIM.
591 Joining a WIM will now preserve the RP_FIX and READONLY flags.
594 On Windows, paths given to wimlib-imagex are now treated case
597 Improved behavior regarding invalid filenames; in particular, on
598 Windows, wimlib-imagex will, when extracting, now omit (with an option
599 to override this default) filenames differing only in case, or filenames
600 containing characters not valid on Windows.
602 On Windows, wimlib now supports capturing and extracting long paths
603 (longer than the so-called MAX_PATH).
605 On Windows, `wimlib-imagex update' now acquires proper privileges when
606 running as an Administrator.
608 `wimlib-imagex update' will now complain if no image is specified when
609 trying to update a multi-image WIM.
611 `wimlib-imagex update' now supports specifying a single update command
612 directly on the command line using the --command option.
614 wimlib-imagex will now choose different units for progress messages,
615 depending on the amount of data that needs to be processed.
617 `wimlib-imagex append' will now generate a unique WIM image name if no
618 name is specified and the defaulted name already exists in the WIM.
620 wimlib now allows you to create unnamed WIM images, which can then only
621 be referred to by index.
623 wimlib now allows you to explicitly declare you want write access to a
624 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
627 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
630 Progress callbacks have been added to wimlib's wimlib_update_image()
633 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
634 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
637 NTFS-3g capture now only warns about two conditions previously treated
640 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
643 wimlib now correctly detects and returns an error when reading a WIM
644 image with a cyclic directory structure. (Fun fact: such a WIM will
645 crash Microsoft's software.)
648 Added new "extract" and "update" subcommands to wimlib-imagex, along
649 with associated APIs in the library. These commands are intended mainly
650 for Windows use but can be used on UNIX as well.
652 Many documentation improvements.
654 Fixed a bug in the Windows build where relative symbolic links were not
655 captured in reparse-point fixup mode.
657 Fixed a bug in the Windows build where file handles were left open to
658 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
660 Fixed a bug in the Windows build of wimlib-imagex where globbing
661 split-WIM parts could cause the program to crash.
663 Fixed a bug where the creation time of WIM images would be shown instead
664 of the last modification time.
666 With the Windows build it is now possible to restore a WIM containing
667 symbolic links as a non-Administrator; however you will receive warnings
668 about not being able to extract the symbolic links.
671 Capturing a WIM image should now be significantly faster in most cases
672 due to improved use of the operating system's cache and avoiding reading
673 files twice whenever possible.
675 The Windows build should now work on Windows XP.
677 The Windows build now supports capturing and restoring hidden,
678 compressed, sparse, and encrypted files.
680 The Windows build now supports capturing and applying WIM images from
681 filesystems other than NTFS (with some reduced functionality).
683 The Windows build now extracts short names correctly.
685 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
686 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
687 capture' and `wimlib-imagex apply'.
689 The performance of splitting and joining WIMs should be slightly
692 The LZX and XPRESS compression and decompression functions are now
693 exported from the library.
696 Improvements and bugfixes for the Windows build.
698 Added --strict-acls options.
700 Fixed the way that wimlib determines the order of images in the WIM.
703 Since wimlib can now be used on Windows, wimlib's implementation of
704 ImageX has been renamed to wimlib-imagex to avoid confusion with
705 Microsoft's implementation of ImageX, which would have the same file
706 name ("imagex.exe"). If you really don't like this you can pass the
707 --with-imagex-progname option to `configure' to choose a different name,
708 or even simply rename the binary yourself (but the former way will
709 configure the man pages to use the chosen name).
711 Various bugs fixed in the Windows build. Mainly to do with capturing
712 and restoring alternate data streams correctly in weird cases, and
713 requesting the correct privileges when opening files. Also added the
714 --noacls options to wimlib-imagex capture, append, and apply.
716 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
717 dynamically loaded, so this may make the library compatible with Windows
718 XP (however, there may still be other problems).
721 Added experimental support for native Windows builds. Binaries can be
722 downloaded from the SourceForge page.
724 --source-list option added to `imagex capture' and `imagex append'.
726 Better support for different character encodings.
729 Storing UNIX file owners, groups, and modes in WIM images is now
730 possible using `imagex capture' with the --unix-data flag.
732 Minor bug fixes and documentation fixes.
735 NTFS capture: Fixed capturing duplicate reparse points.
737 NTFS capture: Capture first unnamed stream if there are more than one
738 (print warning instead of error).
740 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
743 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
746 Update to work with ntfs-3g version 2013.1.13.
749 Fixed truncating file to shorter but non-zero length on read-write
752 Various code cleanups and minor documentation fixes.
755 LZX and XPRESS decompression have received some additional optimizations
756 and should now be even faster. (Although, they were already pretty
757 fast--- much faster than typical I/O speeds.)
759 Fixed a bug introduced in v1.2.1 that would cause a directory tree
760 containing hard links to be captured incorrectly in some cases.
763 By default, unmounting a read-write mounted WIM with 'imagex unmount
764 --commit' will now change the WIM in-place without needing to write the
765 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
768 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
769 for a response from the daemon servicing the mounted WIM. Instead,
770 every second 'imagex unmount' will check if the daemon is still alive,
771 and keep waiting if so, otherwise terminate with an error.
773 'imagex unmount --commit' on a read-write mounted WIM will now print
774 progress information regarding the writing of new or modified streams
775 the WIM, just like when capturing or appending a WIM.
777 A small change has been made to XPRESS compression and it should improve
778 the compression ratio slightly.
780 A change was made that may improve performance slightly when applying a
781 WIM image to a NTFS volume.
783 Microsoft has managed to introduce even more bugs into their software,
784 and now the WIMs for Windows 8 have incorrect (too low) reference counts
785 for some streams. This is unsafe because such streams can be removed
786 when they are in actuality still referenced in the WIM (perhaps by a
787 different image). wimlib will now work around this problem by fixing
788 the stream reference counts. This is only done when wimlib_delete_image() is
789 called ('imagex delete') or when wimlib_mount_image() is called with
790 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
791 requires reading the metadata for all images in the WIM, so this will
792 make these operations noticably slower on WIMs with multiple images.
794 Various other bugfixes.
797 Appending images to a WIM is now be done by default without re-building
798 the whole WIM. Use the --rebuild flag to get the old behavior (which
799 was to re-build the entire WIM when a new image is appended).
801 A new command `imagex optimize' is now available to manually re-build a
802 WIM that has wasted space due to repeated appends.
804 Progress information has been improved, and now arbitrary callback
805 functions can be used to show the progress of a WIM operation.
807 A possible bug with changing the bootable image of a WIM was fixed.
809 Some advisory locking is now done to prevent two processes from
810 modifying a WIM at the same time (but only in some cases). For example,
811 you cannot mount two images from a WIM read-write at the same time.
813 Some functions have been reorganized:
814 * wimlib_mount() renamed to wimlib_mount_image().
815 * wimlib_unmount() renamed to wimlib_unmount_image().
816 * wimlib_overwrite_xml_and_header() removed as
817 wimlib_overwrite() suffices now.
818 * wimlib_apply_image_to_ntfs_volume() removed as
819 wimlib_extract_image() suffices now.
820 * wimlib_add_image_from_ntfs_volume() removed as
821 * wimlib_add_image() suffices now.
823 Previously, the soname of libwim.so has been 0.0.0, despite many
824 interface changes. The soname is now updated to 1.0.0 and will now be
825 updated each release.
828 Resources will now be compressed using multiple threads by default.
829 (This applies to `imagex capture', `imagex append', and `imagex
832 Some performance improvements in mounted WIMs.
834 More progress information is shown when capturing a WIM.
837 Lots of minor fixes, code cleanups, and some documentation updates.
838 Nothing in particular is really noteworthy.
841 LZX and XPRESS compression improvements.
843 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
844 Link Bytes of the WIM.
847 Fixed bug when capturing NTFS file with multiple named data streams.
849 Internally, we are now using inode structures, even though these don't
850 appear literally in the WIM file. This simplifies some of the code
851 (mainly for WIM mounting) and likely fixed a few problems, although it
855 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
859 Enough changes to call it version 1.0.0!
861 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
862 to a NTFS volume, is now supported.
864 Hard links and symbolic links have much improved support. They are
865 supported for WIM capture, WIM application, and mounted WIMs (you can
866 even make them on read-write mounted WIMs).
868 Alternate data streams are now supported on mounted WIMs through an
869 xattr or a Windows-style stream interface. Also they are supported when
870 capturing a WIM from NTFS or applying a WIM to NTFS.
872 Split WIMs are better supported. You may now apply an image directly
873 from a split WIM, mount an image from a split WIM read-only, or export
874 an image from a split WIM.
876 Using a capture configuration file is now supported (but not fully yet).
878 SHA1 message digests are checked in more places, so we can make sure
879 applied and captured data is correct.
881 Man pages have been updated and consolidated.
884 Fixed segfault when unmounting read-only WIM.
887 Support for joining and splitting WIMs.
888 Also, security data is now preserved by default.
891 Can now build with older gcc and system headers, like on CentOS 5.
894 Fixed bug that made it impossible to overwrite files in read-write
898 Write byte-order mark before WIM XML data. (imagex.exe requires this to
