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 Several improvements to System Compression (compact mode) support:
26 wof.sys (or wofadk.sys) is now automatically attached to the
27 target volume if needed.
29 Compact-mode extractions now work correctly with wofadk.sys on
30 older versions of Windows.
32 For compatibility with the Windows bootloader, the requested
33 compression format now is overridden on certain files.
36 This release primarily contains various minor bug fixes and
37 improvements, including:
39 Improved handling of deep directory structures.
41 Fixed a bug where on 32-bit systems, the library could enter an
42 infinite loop if a WIM file was malformed in a specific way.
44 Added a workaround for a case where libntfs-3g may report
45 duplicate streams in an NTFS file.
47 Windows symbolic links and junctions in mounted WIM images are
48 now automatically rewritten to be valid in the mounted location.
50 Reparse point fixes: correctly handle the "ReparseReserved"
51 field, and correctly handle "empty" (data-less) reparse points.
53 On Windows, wimlib now acquires SeManageVolumePrivilege, which
54 is needed to create externally backed files using the
57 Improved validation of filenames.
59 Improved LZMS decompression speed.
61 The configure script now honors alternate pkg-config settings.
63 Links have been updated to point to the new website.
65 In addition, experimental support has been added for compressing
66 extracted files using System Compression on Windows 10. This
67 functionality is available through the new '--compact' option to
68 'wimapply' and 'wimextract' as well as new library flags.
71 Fixed a bug in the LZX decompressor: malicious input data could cause
72 out of bounds writes to memory (since wimlib v1.2.2).
74 The output of the 'wiminfo' command now consolidates various boolean
75 flags (such as "Relative path junction") into a single line.
77 A file can now have both an unnamed data stream ("file contents") and a
78 reparse point stream. Such files can exist as a result of the use of
79 certain Windows features, such as offline storage, including "OneDrive".
80 wimlib will now store and restore both streams on Windows as well as in
81 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
83 On Windows, named data streams of encrypted files are no longer stored
84 twice in WIM archives.
86 On Windows, named data streams are now correctly extracted to existing
87 "readonly" directories. Before, an error would be reported.
89 On Windows, it is now possible to do a "WIMBoot mode" extraction with
90 non-standalone WIMs such as delta WIMs.
92 On Windows, when doing an extraction in "WIMBoot mode", files larger
93 than 4 gigabytes are now never extracted as externally backed. This
94 works around a bug in Microsoft's "WOF" driver.
96 The '--enable-verify-compression' configure option has been removed. If
97 you want to verify a WIM file, use the 'wimverify' program.
99 The way the "file count", "directory count", "total bytes", and "hard
100 link bytes" image statistics (stored in the WIM XML data) is calculated
101 has been slightly changed.
103 In mounted WIM images, the disk usage provided for each file (st_blocks)
104 is now the compressed size rather than the uncompressed size.
106 The performance of the NTFS-3g and Windows capture modes has been
109 On UNIX-like systems, symbolic links whose targets contain the backslash
110 character are now handled correctly (losslessly).
113 Improved the LZX compressor. It is now 15-20% faster than before and
114 provides a slightly better compression ratio.
116 Improved the LZMS compressor. It now provides a compression ratio
117 slightly better than WIMGAPI while still being faster and using slightly
120 The compression chunk size in solid resources, e.g. when capturing or
121 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
122 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
123 better compression ratio and is the same value that WIMGAPI uses. The
124 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
125 lower than WIMGAPI's memory usage, but if it is too much, it is still
126 possible to choose a lower value, e.g. with the '--solid-chunk-size'
127 option to wimlib-imagex.
129 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
130 accept the 'K', 'M', and 'G' suffixes.
132 Files are now sorted by name extension when creating a solid WIM file.
134 Fixed various issues related to capture/apply of EFS-encrypted files on
137 The file list printed by 'wimdir' is now sorted by the platform-specific
138 case sensitivity setting, rather than always case sensitively. This
139 also affects the library function wimlib_iterate_dir_tree().
141 On Windows, some error and warning messages have been improved.
144 The Windows binary distribution no longer contains third party DLLs.
145 These dependencies are instead compiled directly into the libwim DLL.
147 Added more fixes for wimlib on non-x86 architectures such as ARM.
149 Extracting files to a Windows PE in-memory filesystem no longer fails if
150 the target files do not yet exist.
152 Improved the performance of XPRESS compression and LZMS decompression.
154 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
155 It will automatically be faster on newer Intel and AMD processors.
157 Removed the --with-imagex-progname and --enable-more-assertions
161 Fix for very slow export from solid WIM / ESD files.
163 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
165 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
166 may use this to treat some types of errors as non-fatal.
168 The library now permits making in-memory changes to a WIMStruct backed
169 by a read-only WIM file.
171 Fixes for "WIMBoot" extraction mode (Windows only):
173 When not using the WOF driver, extraction no longer fails if the
174 disk containing the WIM file has too many partitions.
176 When matching patterns in [PrepopulateList], all hard links of
177 each file are now considered.
179 The system registry files are now automatically treated as being
180 in [PrepopulateList].
182 Added a hack to try to work around an intermittent bug in
183 Microsoft's WOF (Windows Overlay Filesystem) driver.
186 Made more improvements to the XPRESS, LZX, and LZMS compressors.
188 A number of improvements to the Windows port:
190 Fixes for setting short filenames.
192 Faster "WIMBoot" extraction.
194 Updated and slimmed down the dependent DLLs.
196 ACL inheritence bits are now restored.
198 Mandatory integrity labels are now backed up and restored.
200 Added a workaround for an issue where in rare cases, wimlib could create
201 a compressed data stream that could not be read correctly by Windows
202 after an extraction in "WIMBoot" mode.
205 Added file count progress data for
206 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
207 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
209 Added support for testing file exclusions via the user-provided
212 Some documentation improvements.
214 Made some clarifications to the license text in the COPYING file.
217 Made more improvements to the XPRESS, LZX, and LZMS compressors.
219 The default compression mode for wimcapture is now LZX compression in
220 its default mode, which is the same as '--compress=maximum'.
222 You can now specify an optional integer compression level to the
223 '--compress' option; e.g. '--compress=lzx:75'.
225 Made a minor change to the LZMS compressor and decompressor to fix an
226 incompatibility with the Microsoft implementation. In the unlikely
227 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
228 earlier and a checksum error is reported when extracting files from it
229 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
232 Added 'verify' subcommand to wimlib-imagex.
234 Notable library changes:
236 Custom compressor parameters have been removed from the library
237 in favor of the simpler level-based API.
239 Decompressor parameters have been removed entirely.
241 Library users can now specify a custom file for warning and
242 error messages to be sent to, rather than the default of
245 New progress messages:
246 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
247 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
249 New function: wimlib_verify_wim().
252 Improved compression, decompression, and extraction performance.
254 Improved compatibility with version 3584 WIM / ESD files:
255 - Add support for reading and writing multiple solid blocks per
256 archive, which WIMGAPI/DISM can create when appending an image.
257 - Correctly create solid blocks larger than 4 GiB.
259 'add' commands passed to wimupdate will now replace existing
260 nondirectory files by default. Use the --no-replace option to get the
263 The license for the library now contains an exception that allows using
264 it under the LGPL. See the COPYING file for details.
266 In reparse-point fixup mode (the default for capture), symbolic links
267 and junctions that point outside the tree being captured are no longer
268 excluded from capture.
270 Added support for "WIMBoot" capture and extraction. See the
271 documentation for the new '--wimboot' option to wimcapture and wimapply
272 for more information.
274 On UNIX-like systems, you can now backup and restore device nodes, named
275 pipes, and sockets. In addition, 32-bit user and group IDs are now
278 The way that UNIX data is stored in WIM files has been changed. If you
279 captured any WIMs with the --unix-data option, to upgrade them you'll
280 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
281 re-capture them with --unix-data using this version.
283 wimlib now understands tagged metadata items, such as object IDs, that
284 can be stored in WIM directory entries.
286 Removed the --hardlink and --symlink options to wimapply, since I don't
287 think they are too useful and they got in the way of improving the code.
289 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
291 The 'mkwinpeimg' script now supports writing the ISO image to standard
294 The <ARCH> element in WIM XML data is now exported correctly.
296 On Windows, sparse file attributes are no longer set on extracted files.
297 Oddly enough, this actually saves disk space in some cases.
299 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
300 supported. Mounting WIM images now always requires extended attribute
301 support. Use --without-fuse to disable support for mounting WIM images;
302 this will also disable the need for extended attribute support.
304 Configuring with --enable-ssse3-sha1 now works correctly.
306 The shared library version has been bumped up. The main
307 incompatibilities are:
309 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
310 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
313 - User-provided progress functions are now registered using a
314 separate function, wimlib_register_progress_function(). The
315 'progress_func' argument to many functions no longer exists.
317 - The return value from user-provided progress functions is now
320 - A context argument has been added to the prototype of
321 user-provided progress functions.
323 - 'struct wimlib_capture_config' has been removed. The library
324 now takes the path to the configuration file directly. This
325 affects wimlib_add_image(), wimlib_add_image_multisource(),
326 and wimlib_update_image(). However, a NULL value passed in
327 the argument retains the same meaning.
329 - Removed deprecated functions: some (de)compression functions,
330 wimlib_extract_files(), and wimlib_print_metadata().
332 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
333 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
334 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
336 - Removed some progress messages:
337 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
338 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
339 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
342 - Removed some error codes. Numbering stays the same.
344 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
345 WIMLIB_UNMOUNT_FLAG_FORCE.
347 - WIM paths passed to progress functions now have a leading
351 Case-insensitive comparisons of strings (e.g. filenames) containing
352 UTF-16 codepoints above 32767 are now done correctly.
354 Fixed build failure on Mac OS X.
356 wimunmount now provides the '--new-image' option to cause changes to a
357 read-write mounted image to be committed as a new image rather than as
358 an update of the mounted image. (The corresponding new library flag is
359 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
361 The LZMS ("recovery") compression chunk size, or "dictionary size", may
362 now be up to 1 GiB (1,073,741,824 bytes).
364 The performance of LZX ("maximum") and LZMS ("recovery") compression
365 with large chunk sizes has been slightly improved.
368 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
369 decompressed correctly.
371 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
372 occurred in an unlikely case, and due to validity checks it did not
373 affect successfully created archives.
375 Fixed a minor compatibility issue with the LZMS compressor and
376 decompressor. This is *not* the default compression type and was only
377 introduced in v1.6.0. In the unlikely event that you created an
378 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
379 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
382 Memory usage for LZMS and LZX compression has been decreased.
384 wimextract now allows wildcard characters in paths specified on the
385 command line. Also, the '--strict-wildcards' option has been removed
386 and replaced with the inverse option '--nullglob'. See the
387 documentation for wimextract for more details and changes.
389 The wimlib_extract_files() function is now considered deprecated in
390 favor of wimlib_extract_paths().
392 Fixed more permissions problems when extracting files on Windows.
394 A new '--no-attributes' option has been added to wimapply and
395 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
397 The default chunk size is now set correctly when changing the
398 compression type of a WIM, for example with 'wimoptimize'.
400 The '--metadata' option to wiminfo has been replaced with the
401 '--detailed' option to wimdir.
403 In relevant wimlib-imagex commands, '--solid' may now be used as an
404 alias for '--pack-streams'.
407 Support for extracting and updating the new version 3584 WIMs has been
408 added. These WIMs typically pack many streams ("files") together into a
409 single compressed resource, thereby saving space. This degrades the
410 performance of random access (such as that which occurs on a mounted
411 image), but optimizations have been implemented for extraction. These
412 new WIM files also typically use a new compression format (LZMS), which
413 is similar to LZMA and can offer a better compression ratio than LZX.
414 These new WIM files can be created using `wimcapture' with
415 the '--compress=lzms --pack-streams' options. Note: this new WIM format
416 is used by the Windows 8 web downloader, but important segments of the
417 raw '.esd' files are encrypted, so wimlib will not be able to extract
418 such files until they are first decrypted.
420 wimlib now supports extracting files and directories from a WIM image
421 based on a "listfile" that itself contains the list of paths to extract.
422 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
423 and for the library itself, the new APIs are wimlib_extract_pathlist()
424 and wimlib_extract_paths(). Path globs containing wildcard characters
427 For searching WIM files, wimlib now has configurable case sensitivity.
428 The default on Windows is still case-insensitive and the default on
429 UNIX-like systems is still case-sensitive, but this can be overridden
430 on either platform through flags to wimlib_global_init(). For
431 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
432 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
435 Support for compression chunk sizes greater than the default of 32768
436 bytes has been added. A larger chunk size typically results in a better
437 compression ratio. However, the MS implementation is seemingly not
438 compatible with all chunk sizes, especially for LZX compression, so the
439 defaults remain unchanged, with the exception of the new LZMS-compressed
440 WIMs, which use a larger chunk size by default.
442 The compression/decompression API exported by wimlib has been changed.
443 Now one set of functions handles all supported compression formats.
445 `wimcapture' and `wimappend' will now display the progress of scanning
446 the directory tree to capture, in addition to the progress of writing
447 data to the WIM. The '--verbose' option no longer does anything. The
448 library API change for this is the addition of several members to
449 `struct wimlib_progress_info_scan' available to progress callbacks.
451 `mkwinpeimg' now correctly handles the '--start-script' option when the
452 start script is not in the working directory.
454 Sequential extraction, previously requested by using
455 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
456 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
457 behavior (extract in file order).
460 The new LZX compressor added in v1.5.2 has been improved and is now
461 enabled by default, except when `wimcapture' or `wimappend' is run
462 *without* the '--compress' option, in which case the faster LZX
463 compressor is used (the same as before). This behavior is reasonably
464 consistent with ImageX which actually uses "fast" (XPRESS) compression
465 by default. In those cases, use '--compress=maximum' to explicitly
466 capture a WIM image using the new (slower but better) LZX compressor.
468 The '--compress-slow' option still exists to `wimlib-imagex optimize',
469 but its new behavior is to tweak the new LZX compressor even more to
470 produce an even better compression ratio at the cost of more time spent
473 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
474 which recompresses the WIM file using the specified compression TYPE.
475 The new library API function used for this is
476 wimlib_set_output_compression_type().
478 Added the wimlib_get_xml_data() function to allow library clients to
479 easily retrieve the raw XML data from a WIM file if needed.
481 Fixed a bug that could cause an error code to be incorrectly returned
482 when writing XML data containing a <WINDOWS> element.
484 Mounted WIM images will now correctly show the default file stream even
485 if appears in the alternate data stream entries of the corresponding WIM
489 Added a new experimental LZX compressor which can be enabled by passing
490 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
491 optimize'. (The latter is only applicable if the WIM is already
492 LZX-compressed and the '--recompress' option is also given.) The
493 experimental compressor is much slower but compresses the data slightly
494 more --- currently usually to within a fraction of a percent of the
495 results from WIMGAPI/ImageX.
497 A workaround has been added for compatibility with versions of WinPE
498 that interpret alternate data stream entries in the boot WIM
501 An alignment bug that caused a crash in the LZX decompressor on some
504 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
505 the WIM header when restoring the previous state of a WIM it failed to
508 Added a workaround to avoid an access denied error on Windows when
509 replacing a WIM file that another process has opened.
512 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
513 needed to be handled.
515 A bug in the interpretation of negative IMAGE indices in the
516 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
517 `wimlib-imagex append' has been fixed.
519 A workaround has been added to successfully apply security descriptors
520 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
521 2013.1.13 or earlier.
523 `wimlib-imagex capture' can now accept the '--delta-from' option
527 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
528 to standard output and applying images from standard input, but they are
529 not compatible with Microsoft's software and are not created by default.
530 See the documentation for --pipable flag of `wimlib-imagex capture' for
533 To better support incremental backups, added support for declaring an
534 image as a modified form of another image. See the documentation for
535 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
538 Added supported for "delta" WIMs. See the documentation for the
539 '--delta-from' option of `wimlib-imagex capture'.
541 The library support for managing split WIMs has been changed to support
542 other arrangements, such as delta WIMs, and be easier to use. This
543 change is visible in `wimlib-imagex', which also can now accept the
544 '--ref' option multiple times, and also now supports "delta" WIMs as
547 wimlib now preserves WIM integrity tables by default, even if
548 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
549 behavior of `wimlib-imagex' whenever the WIM being operated on contains
550 an integrity table and the '--check' option is not specified.
552 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
553 (when --compress is not specified). This provides the best compression
554 ratio by default, which is usually what is desired, at a cost of some
557 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
558 is the command as in `wimlib-imagex COMMAND'; for example, it can be
559 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
560 appropriate hard links are created in UNIX installations of
561 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
562 batch files that emulate this behavior are generated.
564 Security descriptors are now extracted correctly on Windows.
566 Fixed archiving DOS names in NTFS-3g capture mode.
568 The extraction code has been rewritten and it will now be easier to
569 support new features on all supported backends (currently Win32, UNIX,
570 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
571 now supported on all backends, not just UNIX.
573 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
574 than the WAIK itself.
576 wimlib_global_init() now, by default, attempts to acquire additional
577 privileges on Windows, so library clients need not do this.
579 This update bumps the shared library version number up to 9, since it is
580 not binary compatibible with previous releases.
583 Fixed bug in `wimlib-imagex export' that made it impossible to export an
584 image from a WIM that is readonly at the filesystem level.
586 Return error code rather than segfaulting when trying to list files from
587 a non-first part of a split WIM.
589 Joining a WIM will now preserve the RP_FIX and READONLY flags.
592 On Windows, paths given to wimlib-imagex are now treated case
595 Improved behavior regarding invalid filenames; in particular, on
596 Windows, wimlib-imagex will, when extracting, now omit (with an option
597 to override this default) filenames differing only in case, or filenames
598 containing characters not valid on Windows.
600 On Windows, wimlib now supports capturing and extracting long paths
601 (longer than the so-called MAX_PATH).
603 On Windows, `wimlib-imagex update' now acquires proper privileges when
604 running as an Administrator.
606 `wimlib-imagex update' will now complain if no image is specified when
607 trying to update a multi-image WIM.
609 `wimlib-imagex update' now supports specifying a single update command
610 directly on the command line using the --command option.
612 wimlib-imagex will now choose different units for progress messages,
613 depending on the amount of data that needs to be processed.
615 `wimlib-imagex append' will now generate a unique WIM image name if no
616 name is specified and the defaulted name already exists in the WIM.
618 wimlib now allows you to create unnamed WIM images, which can then only
619 be referred to by index.
621 wimlib now allows you to explicitly declare you want write access to a
622 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
625 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
628 Progress callbacks have been added to wimlib's wimlib_update_image()
631 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
632 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
635 NTFS-3g capture now only warns about two conditions previously treated
638 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
641 wimlib now correctly detects and returns an error when reading a WIM
642 image with a cyclic directory structure. (Fun fact: such a WIM will
643 crash Microsoft's software.)
646 Added new "extract" and "update" subcommands to wimlib-imagex, along
647 with associated APIs in the library. These commands are intended mainly
648 for Windows use but can be used on UNIX as well.
650 Many documentation improvements.
652 Fixed a bug in the Windows build where relative symbolic links were not
653 captured in reparse-point fixup mode.
655 Fixed a bug in the Windows build where file handles were left open to
656 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
658 Fixed a bug in the Windows build of wimlib-imagex where globbing
659 split-WIM parts could cause the program to crash.
661 Fixed a bug where the creation time of WIM images would be shown instead
662 of the last modification time.
664 With the Windows build it is now possible to restore a WIM containing
665 symbolic links as a non-Administrator; however you will receive warnings
666 about not being able to extract the symbolic links.
669 Capturing a WIM image should now be significantly faster in most cases
670 due to improved use of the operating system's cache and avoiding reading
671 files twice whenever possible.
673 The Windows build should now work on Windows XP.
675 The Windows build now supports capturing and restoring hidden,
676 compressed, sparse, and encrypted files.
678 The Windows build now supports capturing and applying WIM images from
679 filesystems other than NTFS (with some reduced functionality).
681 The Windows build now extracts short names correctly.
683 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
684 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
685 capture' and `wimlib-imagex apply'.
687 The performance of splitting and joining WIMs should be slightly
690 The LZX and XPRESS compression and decompression functions are now
691 exported from the library.
694 Improvements and bugfixes for the Windows build.
696 Added --strict-acls options.
698 Fixed the way that wimlib determines the order of images in the WIM.
701 Since wimlib can now be used on Windows, wimlib's implementation of
702 ImageX has been renamed to wimlib-imagex to avoid confusion with
703 Microsoft's implementation of ImageX, which would have the same file
704 name ("imagex.exe"). If you really don't like this you can pass the
705 --with-imagex-progname option to `configure' to choose a different name,
706 or even simply rename the binary yourself (but the former way will
707 configure the man pages to use the chosen name).
709 Various bugs fixed in the Windows build. Mainly to do with capturing
710 and restoring alternate data streams correctly in weird cases, and
711 requesting the correct privileges when opening files. Also added the
712 --noacls options to wimlib-imagex capture, append, and apply.
714 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
715 dynamically loaded, so this may make the library compatible with Windows
716 XP (however, there may still be other problems).
719 Added experimental support for native Windows builds. Binaries can be
720 downloaded from the SourceForge page.
722 --source-list option added to `imagex capture' and `imagex append'.
724 Better support for different character encodings.
727 Storing UNIX file owners, groups, and modes in WIM images is now
728 possible using `imagex capture' with the --unix-data flag.
730 Minor bug fixes and documentation fixes.
733 NTFS capture: Fixed capturing duplicate reparse points.
735 NTFS capture: Capture first unnamed stream if there are more than one
736 (print warning instead of error).
738 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
741 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
744 Update to work with ntfs-3g version 2013.1.13.
747 Fixed truncating file to shorter but non-zero length on read-write
750 Various code cleanups and minor documentation fixes.
753 LZX and XPRESS decompression have received some additional optimizations
754 and should now be even faster. (Although, they were already pretty
755 fast--- much faster than typical I/O speeds.)
757 Fixed a bug introduced in v1.2.1 that would cause a directory tree
758 containing hard links to be captured incorrectly in some cases.
761 By default, unmounting a read-write mounted WIM with 'imagex unmount
762 --commit' will now change the WIM in-place without needing to write the
763 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
766 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
767 for a response from the daemon servicing the mounted WIM. Instead,
768 every second 'imagex unmount' will check if the daemon is still alive,
769 and keep waiting if so, otherwise terminate with an error.
771 'imagex unmount --commit' on a read-write mounted WIM will now print
772 progress information regarding the writing of new or modified streams
773 the WIM, just like when capturing or appending a WIM.
775 A small change has been made to XPRESS compression and it should improve
776 the compression ratio slightly.
778 A change was made that may improve performance slightly when applying a
779 WIM image to a NTFS volume.
781 Microsoft has managed to introduce even more bugs into their software,
782 and now the WIMs for Windows 8 have incorrect (too low) reference counts
783 for some streams. This is unsafe because such streams can be removed
784 when they are in actuality still referenced in the WIM (perhaps by a
785 different image). wimlib will now work around this problem by fixing
786 the stream reference counts. This is only done when wimlib_delete_image() is
787 called ('imagex delete') or when wimlib_mount_image() is called with
788 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
789 requires reading the metadata for all images in the WIM, so this will
790 make these operations noticably slower on WIMs with multiple images.
792 Various other bugfixes.
795 Appending images to a WIM is now be done by default without re-building
796 the whole WIM. Use the --rebuild flag to get the old behavior (which
797 was to re-build the entire WIM when a new image is appended).
799 A new command `imagex optimize' is now available to manually re-build a
800 WIM that has wasted space due to repeated appends.
802 Progress information has been improved, and now arbitrary callback
803 functions can be used to show the progress of a WIM operation.
805 A possible bug with changing the bootable image of a WIM was fixed.
807 Some advisory locking is now done to prevent two processes from
808 modifying a WIM at the same time (but only in some cases). For example,
809 you cannot mount two images from a WIM read-write at the same time.
811 Some functions have been reorganized:
812 * wimlib_mount() renamed to wimlib_mount_image().
813 * wimlib_unmount() renamed to wimlib_unmount_image().
814 * wimlib_overwrite_xml_and_header() removed as
815 wimlib_overwrite() suffices now.
816 * wimlib_apply_image_to_ntfs_volume() removed as
817 wimlib_extract_image() suffices now.
818 * wimlib_add_image_from_ntfs_volume() removed as
819 * wimlib_add_image() suffices now.
821 Previously, the soname of libwim.so has been 0.0.0, despite many
822 interface changes. The soname is now updated to 1.0.0 and will now be
823 updated each release.
826 Resources will now be compressed using multiple threads by default.
827 (This applies to `imagex capture', `imagex append', and `imagex
830 Some performance improvements in mounted WIMs.
832 More progress information is shown when capturing a WIM.
835 Lots of minor fixes, code cleanups, and some documentation updates.
836 Nothing in particular is really noteworthy.
839 LZX and XPRESS compression improvements.
841 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
842 Link Bytes of the WIM.
845 Fixed bug when capturing NTFS file with multiple named data streams.
847 Internally, we are now using inode structures, even though these don't
848 appear literally in the WIM file. This simplifies some of the code
849 (mainly for WIM mounting) and likely fixed a few problems, although it
853 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
857 Enough changes to call it version 1.0.0!
859 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
860 to a NTFS volume, is now supported.
862 Hard links and symbolic links have much improved support. They are
863 supported for WIM capture, WIM application, and mounted WIMs (you can
864 even make them on read-write mounted WIMs).
866 Alternate data streams are now supported on mounted WIMs through an
867 xattr or a Windows-style stream interface. Also they are supported when
868 capturing a WIM from NTFS or applying a WIM to NTFS.
870 Split WIMs are better supported. You may now apply an image directly
871 from a split WIM, mount an image from a split WIM read-only, or export
872 an image from a split WIM.
874 Using a capture configuration file is now supported (but not fully yet).
876 SHA1 message digests are checked in more places, so we can make sure
877 applied and captured data is correct.
879 Man pages have been updated and consolidated.
882 Fixed segfault when unmounting read-only WIM.
885 Support for joining and splitting WIMs.
886 Also, security data is now preserved by default.
889 Can now build with older gcc and system headers, like on CentOS 5.
892 Fixed bug that made it impossible to overwrite files in read-write
896 Write byte-order mark before WIM XML data. (imagex.exe requires this to
