2 The performance of LZX compression has been improved by 15-20%. This is
3 the default compression mode of wimlib-imagex.
6 The Windows binary distribution no longer contains third party DLLs.
7 These dependencies are instead compiled directly into the libwim DLL.
9 Added more fixes for wimlib on non-x86 architectures such as ARM.
11 Extracting files to a Windows PE in-memory filesystem no longer fails if
12 the target files do not yet exist.
14 Improved the performance of XPRESS compression and LZMS decompression.
16 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
17 It will automatically be faster on newer Intel and AMD processors.
19 Removed the --with-imagex-progname and --enable-more-assertions
23 Fix for very slow export from solid WIM / ESD files.
25 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
27 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
28 may use this to treat some types of errors as non-fatal.
30 The library now permits making in-memory changes to a WIMStruct backed
31 by a read-only WIM file.
33 Fixes for "WIMBoot" extraction mode (Windows only):
35 When not using the WOF driver, extraction no longer fails if the
36 disk containing the WIM file has too many partitions.
38 When matching patterns in [PrepopulateList], all hard links of
39 each file are now considered.
41 The system registry files are now automatically treated as being
44 Added a hack to try to work around an intermittent bug in
45 Microsoft's WOF (Windows Overlay Filesystem) driver.
48 Made more improvements to the XPRESS, LZX, and LZMS compressors.
50 A number of improvements to the Windows port:
52 Fixes for setting short filenames.
54 Faster "WIMBoot" extraction.
56 Updated and slimmed down the dependent DLLs.
58 ACL inheritence bits are now restored.
60 Mandatory integrity labels are now backed up and restored.
62 Added a workaround for an issue where in rare cases, wimlib could create
63 a compressed data stream that could not be read correctly by Windows
64 after an extraction in "WIMBoot" mode.
67 Added file count progress data for
68 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
69 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
71 Added support for testing file exclusions via the user-provided
74 Some documentation improvements.
76 Made some clarifications to the license text in the COPYING file.
79 Made more improvements to the XPRESS, LZX, and LZMS compressors.
81 The default compression mode for wimcapture is now LZX compression in
82 its default mode, which is the same as '--compress=maximum'.
84 You can now specify an optional integer compression level to the
85 '--compress' option; e.g. '--compress=lzx:75'.
87 Made a minor change to the LZMS compressor and decompressor to fix an
88 incompatibility with the Microsoft implementation. In the unlikely
89 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
90 earlier and a checksum error is reported when extracting files from it
91 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
94 Added 'verify' subcommand to wimlib-imagex.
96 Notable library changes:
98 Custom compressor parameters have been removed from the library
99 in favor of the simpler level-based API.
101 Decompressor parameters have been removed entirely.
103 Library users can now specify a custom file for warning and
104 error messages to be sent to, rather than the default of
107 New progress messages:
108 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
109 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
111 New function: wimlib_verify_wim().
114 Improved compression, decompression, and extraction performance.
116 Improved compatibility with version 3584 WIM / ESD files:
117 - Add support for reading and writing multiple solid blocks per
118 archive, which WIMGAPI/DISM can create when appending an image.
119 - Correctly create solid blocks larger than 4 GiB.
121 'add' commands passed to wimupdate will now replace existing
122 nondirectory files by default. Use the --no-replace option to get the
125 The license for the library now contains an exception that allows using
126 it under the LGPL. See the COPYING file for details.
128 In reparse-point fixup mode (the default for capture), symbolic links
129 and junctions that point outside the tree being captured are no longer
130 excluded from capture.
132 Added support for "WIMBoot" capture and extraction. See the
133 documentation for the new '--wimboot' option to wimcapture and wimapply
134 for more information.
136 On UNIX-like systems, you can now backup and restore device nodes, named
137 pipes, and sockets. In addition, 32-bit user and group IDs are now
140 The way that UNIX data is stored in WIM files has been changed. If you
141 captured any WIMs with the --unix-data option, to upgrade them you'll
142 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
143 re-capture them with --unix-data using this version.
145 wimlib now understands tagged metadata items, such as object IDs, that
146 can be stored in WIM directory entries.
148 Removed the --hardlink and --symlink options to wimapply, since I don't
149 think they are too useful and they got in the way of improving the code.
151 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
153 The 'mkwinpeimg' script now supports writing the ISO image to standard
156 The <ARCH> element in WIM XML data is now exported correctly.
158 On Windows, sparse file attributes are no longer set on extracted files.
159 Oddly enough, this actually saves disk space in some cases.
161 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
162 supported. Mounting WIM images now always requires extended attribute
163 support. Use --without-fuse to disable support for mounting WIM images;
164 this will also disable the need for extended attribute support.
166 Configuring with --enable-ssse3-sha1 now works correctly.
168 The shared library version has been bumped up. The main
169 incompatibilities are:
171 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
172 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
175 - User-provided progress functions are now registered using a
176 separate function, wimlib_register_progress_function(). The
177 'progress_func' argument to many functions no longer exists.
179 - The return value from user-provided progress functions is now
182 - A context argument has been added to the prototype of
183 user-provided progress functions.
185 - 'struct wimlib_capture_config' has been removed. The library
186 now takes the path to the configuration file directly. This
187 affects wimlib_add_image(), wimlib_add_image_multisource(),
188 and wimlib_update_image(). However, a NULL value passed in
189 the argument retains the same meaning.
191 - Removed deprecated functions: some (de)compression functions,
192 wimlib_extract_files(), and wimlib_print_metadata().
194 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
195 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
196 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
198 - Removed some progress messages:
199 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
200 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
201 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
204 - Removed some error codes. Numbering stays the same.
206 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
207 WIMLIB_UNMOUNT_FLAG_FORCE.
209 - WIM paths passed to progress functions now have a leading
213 Case-insensitive comparisons of strings (e.g. filenames) containing
214 UTF-16 codepoints above 32767 are now done correctly.
216 Fixed build failure on Mac OS X.
218 wimunmount now provides the '--new-image' option to cause changes to a
219 read-write mounted image to be committed as a new image rather than as
220 an update of the mounted image. (The corresponding new library flag is
221 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
223 The LZMS ("recovery") compression chunk size, or "dictionary size", may
224 now be up to 1 GiB (1,073,741,824 bytes).
226 The performance of LZX ("maximum") and LZMS ("recovery") compression
227 with large chunk sizes has been slightly improved.
230 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
231 decompressed correctly.
233 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
234 occurred in an unlikely case, and due to validity checks it did not
235 affect successfully created archives.
237 Fixed a minor compatibility issue with the LZMS compressor and
238 decompressor. This is *not* the default compression type and was only
239 introduced in v1.6.0. In the unlikely event that you created an
240 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
241 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
244 Memory usage for LZMS and LZX compression has been decreased.
246 wimextract now allows wildcard characters in paths specified on the
247 command line. Also, the '--strict-wildcards' option has been removed
248 and replaced with the inverse option '--nullglob'. See the
249 documentation for wimextract for more details and changes.
251 The wimlib_extract_files() function is now considered deprecated in
252 favor of wimlib_extract_paths().
254 Fixed more permissions problems when extracting files on Windows.
256 A new '--no-attributes' option has been added to wimapply and
257 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
259 The default chunk size is now set correctly when changing the
260 compression type of a WIM, for example with 'wimoptimize'.
262 The '--metadata' option to wiminfo has been replaced with the
263 '--detailed' option to wimdir.
265 In relevant wimlib-imagex commands, '--solid' may now be used as an
266 alias for '--pack-streams'.
269 Support for extracting and updating the new version 3584 WIMs has been
270 added. These WIMs typically pack many streams ("files") together into a
271 single compressed resource, thereby saving space. This degrades the
272 performance of random access (such as that which occurs on a mounted
273 image), but optimizations have been implemented for extraction. These
274 new WIM files also typically use a new compression format (LZMS), which
275 is similar to LZMA and can offer a better compression ratio than LZX.
276 These new WIM files can be created using `wimcapture' with
277 the '--compress=lzms --pack-streams' options. Note: this new WIM format
278 is used by the Windows 8 web downloader, but important segments of the
279 raw '.esd' files are encrypted, so wimlib will not be able to extract
280 such files until they are first decrypted.
282 wimlib now supports extracting files and directories from a WIM image
283 based on a "listfile" that itself contains the list of paths to extract.
284 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
285 and for the library itself, the new APIs are wimlib_extract_pathlist()
286 and wimlib_extract_paths(). Path globs containing wildcard characters
289 For searching WIM files, wimlib now has configurable case sensitivity.
290 The default on Windows is still case-insensitive and the default on
291 UNIX-like systems is still case-sensitive, but this can be overridden
292 on either platform through flags to wimlib_global_init(). For
293 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
294 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
297 Support for compression chunk sizes greater than the default of 32768
298 bytes has been added. A larger chunk size typically results in a better
299 compression ratio. However, the MS implementation is seemingly not
300 compatible with all chunk sizes, especially for LZX compression, so the
301 defaults remain unchanged, with the exception of the new LZMS-compressed
302 WIMs, which use a larger chunk size by default.
304 The compression/decompression API exported by wimlib has been changed.
305 Now one set of functions handles all supported compression formats.
307 `wimcapture' and `wimappend' will now display the progress of scanning
308 the directory tree to capture, in addition to the progress of writing
309 data to the WIM. The '--verbose' option no longer does anything. The
310 library API change for this is the addition of several members to
311 `struct wimlib_progress_info_scan' available to progress callbacks.
313 `mkwinpeimg' now correctly handles the '--start-script' option when the
314 start script is not in the working directory.
316 Sequential extraction, previously requested by using
317 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
318 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
319 behavior (extract in file order).
322 The new LZX compressor added in v1.5.2 has been improved and is now
323 enabled by default, except when `wimcapture' or `wimappend' is run
324 *without* the '--compress' option, in which case the faster LZX
325 compressor is used (the same as before). This behavior is reasonably
326 consistent with ImageX which actually uses "fast" (XPRESS) compression
327 by default. In those cases, use '--compress=maximum' to explicitly
328 capture a WIM image using the new (slower but better) LZX compressor.
330 The '--compress-slow' option still exists to `wimlib-imagex optimize',
331 but its new behavior is to tweak the new LZX compressor even more to
332 produce an even better compression ratio at the cost of more time spent
335 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
336 which recompresses the WIM file using the specified compression TYPE.
337 The new library API function used for this is
338 wimlib_set_output_compression_type().
340 Added the wimlib_get_xml_data() function to allow library clients to
341 easily retrieve the raw XML data from a WIM file if needed.
343 Fixed a bug that could cause an error code to be incorrectly returned
344 when writing XML data containing a <WINDOWS> element.
346 Mounted WIM images will now correctly show the default file stream even
347 if appears in the alternate data stream entries of the corresponding WIM
351 Added a new experimental LZX compressor which can be enabled by passing
352 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
353 optimize'. (The latter is only applicable if the WIM is already
354 LZX-compressed and the '--recompress' option is also given.) The
355 experimental compressor is much slower but compresses the data slightly
356 more --- currently usually to within a fraction of a percent of the
357 results from WIMGAPI/ImageX.
359 A workaround has been added for compatibility with versions of WinPE
360 that interpret alternate data stream entries in the boot WIM
363 An alignment bug that caused a crash in the LZX decompressor on some
366 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
367 the WIM header when restoring the previous state of a WIM it failed to
370 Added a workaround to avoid an access denied error on Windows when
371 replacing a WIM file that another process has opened.
374 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
375 needed to be handled.
377 A bug in the interpretation of negative IMAGE indices in the
378 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
379 `wimlib-imagex append' has been fixed.
381 A workaround has been added to successfully apply security descriptors
382 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
383 2013.1.13 or earlier.
385 `wimlib-imagex capture' can now accept the '--delta-from' option
389 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
390 to standard output and applying images from standard input, but they are
391 not compatible with Microsoft's software and are not created by default.
392 See the documentation for --pipable flag of `wimlib-imagex capture' for
395 To better support incremental backups, added support for declaring an
396 image as a modified form of another image. See the documentation for
397 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
400 Added supported for "delta" WIMs. See the documentation for the
401 '--delta-from' option of `wimlib-imagex capture'.
403 The library support for managing split WIMs has been changed to support
404 other arrangements, such as delta WIMs, and be easier to use. This
405 change is visible in `wimlib-imagex', which also can now accept the
406 '--ref' option multiple times, and also now supports "delta" WIMs as
409 wimlib now preserves WIM integrity tables by default, even if
410 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
411 behavior of `wimlib-imagex' whenever the WIM being operated on contains
412 an integrity table and the '--check' option is not specified.
414 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
415 (when --compress is not specified). This provides the best compression
416 ratio by default, which is usually what is desired, at a cost of some
419 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
420 is the command as in `wimlib-imagex COMMAND'; for example, it can be
421 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
422 appropriate hard links are created in UNIX installations of
423 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
424 batch files that emulate this behavior are generated.
426 Security descriptors are now extracted correctly on Windows.
428 Fixed archiving DOS names in NTFS-3g capture mode.
430 The extraction code has been rewritten and it will now be easier to
431 support new features on all supported backends (currently Win32, UNIX,
432 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
433 now supported on all backends, not just UNIX.
435 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
436 than the WAIK itself.
438 wimlib_global_init() now, by default, attempts to acquire additional
439 privileges on Windows, so library clients need not do this.
441 This update bumps the shared library version number up to 9, since it is
442 not binary compatibible with previous releases.
445 Fixed bug in `wimlib-imagex export' that made it impossible to export an
446 image from a WIM that is readonly at the filesystem level.
448 Return error code rather than segfaulting when trying to list files from
449 a non-first part of a split WIM.
451 Joining a WIM will now preserve the RP_FIX and READONLY flags.
454 On Windows, paths given to wimlib-imagex are now treated case
457 Improved behavior regarding invalid filenames; in particular, on
458 Windows, wimlib-imagex will, when extracting, now omit (with an option
459 to override this default) filenames differing only in case, or filenames
460 containing characters not valid on Windows.
462 On Windows, wimlib now supports capturing and extracting long paths
463 (longer than the so-called MAX_PATH).
465 On Windows, `wimlib-imagex update' now acquires proper privileges when
466 running as an Administrator.
468 `wimlib-imagex update' will now complain if no image is specified when
469 trying to update a multi-image WIM.
471 `wimlib-imagex update' now supports specifying a single update command
472 directly on the command line using the --command option.
474 wimlib-imagex will now choose different units for progress messages,
475 depending on the amount of data that needs to be processed.
477 `wimlib-imagex append' will now generate a unique WIM image name if no
478 name is specified and the defaulted name already exists in the WIM.
480 wimlib now allows you to create unnamed WIM images, which can then only
481 be referred to by index.
483 wimlib now allows you to explicitly declare you want write access to a
484 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
487 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
490 Progress callbacks have been added to wimlib's wimlib_update_image()
493 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
494 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
497 NTFS-3g capture now only warns about two conditions previously treated
500 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
503 wimlib now correctly detects and returns an error when reading a WIM
504 image with a cyclic directory structure. (Fun fact: such a WIM will
505 crash Microsoft's software.)
508 Added new "extract" and "update" subcommands to wimlib-imagex, along
509 with associated APIs in the library. These commands are intended mainly
510 for Windows use but can be used on UNIX as well.
512 Many documentation improvements.
514 Fixed a bug in the Windows build where relative symbolic links were not
515 captured in reparse-point fixup mode.
517 Fixed a bug in the Windows build where file handles were left open to
518 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
520 Fixed a bug in the Windows build of wimlib-imagex where globbing
521 split-WIM parts could cause the program to crash.
523 Fixed a bug where the creation time of WIM images would be shown instead
524 of the last modification time.
526 With the Windows build it is now possible to restore a WIM containing
527 symbolic links as a non-Administrator; however you will receive warnings
528 about not being able to extract the symbolic links.
531 Capturing a WIM image should now be significantly faster in most cases
532 due to improved use of the operating system's cache and avoiding reading
533 files twice whenever possible.
535 The Windows build should now work on Windows XP.
537 The Windows build now supports capturing and restoring hidden,
538 compressed, sparse, and encrypted files.
540 The Windows build now supports capturing and applying WIM images from
541 filesystems other than NTFS (with some reduced functionality).
543 The Windows build now extracts short names correctly.
545 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
546 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
547 capture' and `wimlib-imagex apply'.
549 The performance of splitting and joining WIMs should be slightly
552 The LZX and XPRESS compression and decompression functions are now
553 exported from the library.
556 Improvements and bugfixes for the Windows build.
558 Added --strict-acls options.
560 Fixed the way that wimlib determines the order of images in the WIM.
563 Since wimlib can now be used on Windows, wimlib's implementation of
564 ImageX has been renamed to wimlib-imagex to avoid confusion with
565 Microsoft's implementation of ImageX, which would have the same file
566 name ("imagex.exe"). If you really don't like this you can pass the
567 --with-imagex-progname option to `configure' to choose a different name,
568 or even simply rename the binary yourself (but the former way will
569 configure the man pages to use the chosen name).
571 Various bugs fixed in the Windows build. Mainly to do with capturing
572 and restoring alternate data streams correctly in weird cases, and
573 requesting the correct privileges when opening files. Also added the
574 --noacls options to wimlib-imagex capture, append, and apply.
576 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
577 dynamically loaded, so this may make the library compatible with Windows
578 XP (however, there may still be other problems).
581 Added experimental support for native Windows builds. Binaries can be
582 downloaded from the SourceForge page.
584 --source-list option added to `imagex capture' and `imagex append'.
586 Better support for different character encodings.
589 Storing UNIX file owners, groups, and modes in WIM images is now
590 possible using `imagex capture' with the --unix-data flag.
592 Minor bug fixes and documentation fixes.
595 NTFS capture: Fixed capturing duplicate reparse points.
597 NTFS capture: Capture first unnamed stream if there are more than one
598 (print warning instead of error).
600 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
603 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
606 Update to work with ntfs-3g version 2013.1.13.
609 Fixed truncating file to shorter but non-zero length on read-write
612 Various code cleanups and minor documentation fixes.
615 LZX and XPRESS decompression have received some additional optimizations
616 and should now be even faster. (Although, they were already pretty
617 fast--- much faster than typical I/O speeds.)
619 Fixed a bug introduced in v1.2.1 that would cause a directory tree
620 containing hard links to be captured incorrectly in some cases.
623 By default, unmounting a read-write mounted WIM with 'imagex unmount
624 --commit' will now change the WIM in-place without needing to write the
625 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
628 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
629 for a response from the daemon servicing the mounted WIM. Instead,
630 every second 'imagex unmount' will check if the daemon is still alive,
631 and keep waiting if so, otherwise terminate with an error.
633 'imagex unmount --commit' on a read-write mounted WIM will now print
634 progress information regarding the writing of new or modified streams
635 the WIM, just like when capturing or appending a WIM.
637 A small change has been made to XPRESS compression and it should improve
638 the compression ratio slightly.
640 A change was made that may improve performance slightly when applying a
641 WIM image to a NTFS volume.
643 Microsoft has managed to introduce even more bugs into their software,
644 and now the WIMs for Windows 8 have incorrect (too low) reference counts
645 for some streams. This is unsafe because such streams can be removed
646 when they are in actuality still referenced in the WIM (perhaps by a
647 different image). wimlib will now work around this problem by fixing
648 the stream reference counts. This is only done when wimlib_delete_image() is
649 called ('imagex delete') or when wimlib_mount_image() is called with
650 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
651 requires reading the metadata for all images in the WIM, so this will
652 make these operations noticably slower on WIMs with multiple images.
654 Various other bugfixes.
657 Appending images to a WIM is now be done by default without re-building
658 the whole WIM. Use the --rebuild flag to get the old behavior (which
659 was to re-build the entire WIM when a new image is appended).
661 A new command `imagex optimize' is now available to manually re-build a
662 WIM that has wasted space due to repeated appends.
664 Progress information has been improved, and now arbitrary callback
665 functions can be used to show the progress of a WIM operation.
667 A possible bug with changing the bootable image of a WIM was fixed.
669 Some advisory locking is now done to prevent two processes from
670 modifying a WIM at the same time (but only in some cases). For example,
671 you cannot mount two images from a WIM read-write at the same time.
673 Some functions have been reorganized:
674 * wimlib_mount() renamed to wimlib_mount_image().
675 * wimlib_unmount() renamed to wimlib_unmount_image().
676 * wimlib_overwrite_xml_and_header() removed as
677 wimlib_overwrite() suffices now.
678 * wimlib_apply_image_to_ntfs_volume() removed as
679 wimlib_extract_image() suffices now.
680 * wimlib_add_image_from_ntfs_volume() removed as
681 * wimlib_add_image() suffices now.
683 Previously, the soname of libwim.so has been 0.0.0, despite many
684 interface changes. The soname is now updated to 1.0.0 and will now be
685 updated each release.
688 Resources will now be compressed using multiple threads by default.
689 (This applies to `imagex capture', `imagex append', and `imagex
692 Some performance improvements in mounted WIMs.
694 More progress information is shown when capturing a WIM.
697 Lots of minor fixes, code cleanups, and some documentation updates.
698 Nothing in particular is really noteworthy.
701 LZX and XPRESS compression improvements.
703 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
704 Link Bytes of the WIM.
707 Fixed bug when capturing NTFS file with multiple named data streams.
709 Internally, we are now using inode structures, even though these don't
710 appear literally in the WIM file. This simplifies some of the code
711 (mainly for WIM mounting) and likely fixed a few problems, although it
715 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
719 Enough changes to call it version 1.0.0!
721 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
722 to a NTFS volume, is now supported.
724 Hard links and symbolic links have much improved support. They are
725 supported for WIM capture, WIM application, and mounted WIMs (you can
726 even make them on read-write mounted WIMs).
728 Alternate data streams are now supported on mounted WIMs through an
729 xattr or a Windows-style stream interface. Also they are supported when
730 capturing a WIM from NTFS or applying a WIM to NTFS.
732 Split WIMs are better supported. You may now apply an image directly
733 from a split WIM, mount an image from a split WIM read-only, or export
734 an image from a split WIM.
736 Using a capture configuration file is now supported (but not fully yet).
738 SHA1 message digests are checked in more places, so we can make sure
739 applied and captured data is correct.
741 Man pages have been updated and consolidated.
744 Fixed segfault when unmounting read-only WIM.
747 Support for joining and splitting WIMs.
748 Also, security data is now preserved by default.
751 Can now build with older gcc and system headers, like on CentOS 5.
754 Fixed bug that made it impossible to overwrite files in read-write
758 Write byte-order mark before WIM XML data. (imagex.exe requires this to
