2 The performance of LZX compression has been improved by 15-20%. This is
3 the default compression mode of wimlib-imagex.
5 The file list printed by 'wimdir' is now sorted by the platform-specific
6 case sensitivity setting, rather than always case sensitively. This
7 also affects the library function wimlib_iterate_dir_tree().
10 The Windows binary distribution no longer contains third party DLLs.
11 These dependencies are instead compiled directly into the libwim DLL.
13 Added more fixes for wimlib on non-x86 architectures such as ARM.
15 Extracting files to a Windows PE in-memory filesystem no longer fails if
16 the target files do not yet exist.
18 Improved the performance of XPRESS compression and LZMS decompression.
20 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
21 It will automatically be faster on newer Intel and AMD processors.
23 Removed the --with-imagex-progname and --enable-more-assertions
27 Fix for very slow export from solid WIM / ESD files.
29 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
31 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
32 may use this to treat some types of errors as non-fatal.
34 The library now permits making in-memory changes to a WIMStruct backed
35 by a read-only WIM file.
37 Fixes for "WIMBoot" extraction mode (Windows only):
39 When not using the WOF driver, extraction no longer fails if the
40 disk containing the WIM file has too many partitions.
42 When matching patterns in [PrepopulateList], all hard links of
43 each file are now considered.
45 The system registry files are now automatically treated as being
48 Added a hack to try to work around an intermittent bug in
49 Microsoft's WOF (Windows Overlay Filesystem) driver.
52 Made more improvements to the XPRESS, LZX, and LZMS compressors.
54 A number of improvements to the Windows port:
56 Fixes for setting short filenames.
58 Faster "WIMBoot" extraction.
60 Updated and slimmed down the dependent DLLs.
62 ACL inheritence bits are now restored.
64 Mandatory integrity labels are now backed up and restored.
66 Added a workaround for an issue where in rare cases, wimlib could create
67 a compressed data stream that could not be read correctly by Windows
68 after an extraction in "WIMBoot" mode.
71 Added file count progress data for
72 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
73 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
75 Added support for testing file exclusions via the user-provided
78 Some documentation improvements.
80 Made some clarifications to the license text in the COPYING file.
83 Made more improvements to the XPRESS, LZX, and LZMS compressors.
85 The default compression mode for wimcapture is now LZX compression in
86 its default mode, which is the same as '--compress=maximum'.
88 You can now specify an optional integer compression level to the
89 '--compress' option; e.g. '--compress=lzx:75'.
91 Made a minor change to the LZMS compressor and decompressor to fix an
92 incompatibility with the Microsoft implementation. In the unlikely
93 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
94 earlier and a checksum error is reported when extracting files from it
95 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
98 Added 'verify' subcommand to wimlib-imagex.
100 Notable library changes:
102 Custom compressor parameters have been removed from the library
103 in favor of the simpler level-based API.
105 Decompressor parameters have been removed entirely.
107 Library users can now specify a custom file for warning and
108 error messages to be sent to, rather than the default of
111 New progress messages:
112 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
113 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
115 New function: wimlib_verify_wim().
118 Improved compression, decompression, and extraction performance.
120 Improved compatibility with version 3584 WIM / ESD files:
121 - Add support for reading and writing multiple solid blocks per
122 archive, which WIMGAPI/DISM can create when appending an image.
123 - Correctly create solid blocks larger than 4 GiB.
125 'add' commands passed to wimupdate will now replace existing
126 nondirectory files by default. Use the --no-replace option to get the
129 The license for the library now contains an exception that allows using
130 it under the LGPL. See the COPYING file for details.
132 In reparse-point fixup mode (the default for capture), symbolic links
133 and junctions that point outside the tree being captured are no longer
134 excluded from capture.
136 Added support for "WIMBoot" capture and extraction. See the
137 documentation for the new '--wimboot' option to wimcapture and wimapply
138 for more information.
140 On UNIX-like systems, you can now backup and restore device nodes, named
141 pipes, and sockets. In addition, 32-bit user and group IDs are now
144 The way that UNIX data is stored in WIM files has been changed. If you
145 captured any WIMs with the --unix-data option, to upgrade them you'll
146 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
147 re-capture them with --unix-data using this version.
149 wimlib now understands tagged metadata items, such as object IDs, that
150 can be stored in WIM directory entries.
152 Removed the --hardlink and --symlink options to wimapply, since I don't
153 think they are too useful and they got in the way of improving the code.
155 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
157 The 'mkwinpeimg' script now supports writing the ISO image to standard
160 The <ARCH> element in WIM XML data is now exported correctly.
162 On Windows, sparse file attributes are no longer set on extracted files.
163 Oddly enough, this actually saves disk space in some cases.
165 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
166 supported. Mounting WIM images now always requires extended attribute
167 support. Use --without-fuse to disable support for mounting WIM images;
168 this will also disable the need for extended attribute support.
170 Configuring with --enable-ssse3-sha1 now works correctly.
172 The shared library version has been bumped up. The main
173 incompatibilities are:
175 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
176 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
179 - User-provided progress functions are now registered using a
180 separate function, wimlib_register_progress_function(). The
181 'progress_func' argument to many functions no longer exists.
183 - The return value from user-provided progress functions is now
186 - A context argument has been added to the prototype of
187 user-provided progress functions.
189 - 'struct wimlib_capture_config' has been removed. The library
190 now takes the path to the configuration file directly. This
191 affects wimlib_add_image(), wimlib_add_image_multisource(),
192 and wimlib_update_image(). However, a NULL value passed in
193 the argument retains the same meaning.
195 - Removed deprecated functions: some (de)compression functions,
196 wimlib_extract_files(), and wimlib_print_metadata().
198 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
199 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
200 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
202 - Removed some progress messages:
203 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
204 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
205 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
208 - Removed some error codes. Numbering stays the same.
210 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
211 WIMLIB_UNMOUNT_FLAG_FORCE.
213 - WIM paths passed to progress functions now have a leading
217 Case-insensitive comparisons of strings (e.g. filenames) containing
218 UTF-16 codepoints above 32767 are now done correctly.
220 Fixed build failure on Mac OS X.
222 wimunmount now provides the '--new-image' option to cause changes to a
223 read-write mounted image to be committed as a new image rather than as
224 an update of the mounted image. (The corresponding new library flag is
225 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
227 The LZMS ("recovery") compression chunk size, or "dictionary size", may
228 now be up to 1 GiB (1,073,741,824 bytes).
230 The performance of LZX ("maximum") and LZMS ("recovery") compression
231 with large chunk sizes has been slightly improved.
234 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
235 decompressed correctly.
237 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
238 occurred in an unlikely case, and due to validity checks it did not
239 affect successfully created archives.
241 Fixed a minor compatibility issue with the LZMS compressor and
242 decompressor. This is *not* the default compression type and was only
243 introduced in v1.6.0. In the unlikely event that you created an
244 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
245 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
248 Memory usage for LZMS and LZX compression has been decreased.
250 wimextract now allows wildcard characters in paths specified on the
251 command line. Also, the '--strict-wildcards' option has been removed
252 and replaced with the inverse option '--nullglob'. See the
253 documentation for wimextract for more details and changes.
255 The wimlib_extract_files() function is now considered deprecated in
256 favor of wimlib_extract_paths().
258 Fixed more permissions problems when extracting files on Windows.
260 A new '--no-attributes' option has been added to wimapply and
261 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
263 The default chunk size is now set correctly when changing the
264 compression type of a WIM, for example with 'wimoptimize'.
266 The '--metadata' option to wiminfo has been replaced with the
267 '--detailed' option to wimdir.
269 In relevant wimlib-imagex commands, '--solid' may now be used as an
270 alias for '--pack-streams'.
273 Support for extracting and updating the new version 3584 WIMs has been
274 added. These WIMs typically pack many streams ("files") together into a
275 single compressed resource, thereby saving space. This degrades the
276 performance of random access (such as that which occurs on a mounted
277 image), but optimizations have been implemented for extraction. These
278 new WIM files also typically use a new compression format (LZMS), which
279 is similar to LZMA and can offer a better compression ratio than LZX.
280 These new WIM files can be created using `wimcapture' with
281 the '--compress=lzms --pack-streams' options. Note: this new WIM format
282 is used by the Windows 8 web downloader, but important segments of the
283 raw '.esd' files are encrypted, so wimlib will not be able to extract
284 such files until they are first decrypted.
286 wimlib now supports extracting files and directories from a WIM image
287 based on a "listfile" that itself contains the list of paths to extract.
288 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
289 and for the library itself, the new APIs are wimlib_extract_pathlist()
290 and wimlib_extract_paths(). Path globs containing wildcard characters
293 For searching WIM files, wimlib now has configurable case sensitivity.
294 The default on Windows is still case-insensitive and the default on
295 UNIX-like systems is still case-sensitive, but this can be overridden
296 on either platform through flags to wimlib_global_init(). For
297 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
298 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
301 Support for compression chunk sizes greater than the default of 32768
302 bytes has been added. A larger chunk size typically results in a better
303 compression ratio. However, the MS implementation is seemingly not
304 compatible with all chunk sizes, especially for LZX compression, so the
305 defaults remain unchanged, with the exception of the new LZMS-compressed
306 WIMs, which use a larger chunk size by default.
308 The compression/decompression API exported by wimlib has been changed.
309 Now one set of functions handles all supported compression formats.
311 `wimcapture' and `wimappend' will now display the progress of scanning
312 the directory tree to capture, in addition to the progress of writing
313 data to the WIM. The '--verbose' option no longer does anything. The
314 library API change for this is the addition of several members to
315 `struct wimlib_progress_info_scan' available to progress callbacks.
317 `mkwinpeimg' now correctly handles the '--start-script' option when the
318 start script is not in the working directory.
320 Sequential extraction, previously requested by using
321 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
322 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
323 behavior (extract in file order).
326 The new LZX compressor added in v1.5.2 has been improved and is now
327 enabled by default, except when `wimcapture' or `wimappend' is run
328 *without* the '--compress' option, in which case the faster LZX
329 compressor is used (the same as before). This behavior is reasonably
330 consistent with ImageX which actually uses "fast" (XPRESS) compression
331 by default. In those cases, use '--compress=maximum' to explicitly
332 capture a WIM image using the new (slower but better) LZX compressor.
334 The '--compress-slow' option still exists to `wimlib-imagex optimize',
335 but its new behavior is to tweak the new LZX compressor even more to
336 produce an even better compression ratio at the cost of more time spent
339 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
340 which recompresses the WIM file using the specified compression TYPE.
341 The new library API function used for this is
342 wimlib_set_output_compression_type().
344 Added the wimlib_get_xml_data() function to allow library clients to
345 easily retrieve the raw XML data from a WIM file if needed.
347 Fixed a bug that could cause an error code to be incorrectly returned
348 when writing XML data containing a <WINDOWS> element.
350 Mounted WIM images will now correctly show the default file stream even
351 if appears in the alternate data stream entries of the corresponding WIM
355 Added a new experimental LZX compressor which can be enabled by passing
356 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
357 optimize'. (The latter is only applicable if the WIM is already
358 LZX-compressed and the '--recompress' option is also given.) The
359 experimental compressor is much slower but compresses the data slightly
360 more --- currently usually to within a fraction of a percent of the
361 results from WIMGAPI/ImageX.
363 A workaround has been added for compatibility with versions of WinPE
364 that interpret alternate data stream entries in the boot WIM
367 An alignment bug that caused a crash in the LZX decompressor on some
370 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
371 the WIM header when restoring the previous state of a WIM it failed to
374 Added a workaround to avoid an access denied error on Windows when
375 replacing a WIM file that another process has opened.
378 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
379 needed to be handled.
381 A bug in the interpretation of negative IMAGE indices in the
382 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
383 `wimlib-imagex append' has been fixed.
385 A workaround has been added to successfully apply security descriptors
386 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
387 2013.1.13 or earlier.
389 `wimlib-imagex capture' can now accept the '--delta-from' option
393 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
394 to standard output and applying images from standard input, but they are
395 not compatible with Microsoft's software and are not created by default.
396 See the documentation for --pipable flag of `wimlib-imagex capture' for
399 To better support incremental backups, added support for declaring an
400 image as a modified form of another image. See the documentation for
401 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
404 Added supported for "delta" WIMs. See the documentation for the
405 '--delta-from' option of `wimlib-imagex capture'.
407 The library support for managing split WIMs has been changed to support
408 other arrangements, such as delta WIMs, and be easier to use. This
409 change is visible in `wimlib-imagex', which also can now accept the
410 '--ref' option multiple times, and also now supports "delta" WIMs as
413 wimlib now preserves WIM integrity tables by default, even if
414 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
415 behavior of `wimlib-imagex' whenever the WIM being operated on contains
416 an integrity table and the '--check' option is not specified.
418 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
419 (when --compress is not specified). This provides the best compression
420 ratio by default, which is usually what is desired, at a cost of some
423 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
424 is the command as in `wimlib-imagex COMMAND'; for example, it can be
425 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
426 appropriate hard links are created in UNIX installations of
427 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
428 batch files that emulate this behavior are generated.
430 Security descriptors are now extracted correctly on Windows.
432 Fixed archiving DOS names in NTFS-3g capture mode.
434 The extraction code has been rewritten and it will now be easier to
435 support new features on all supported backends (currently Win32, UNIX,
436 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
437 now supported on all backends, not just UNIX.
439 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
440 than the WAIK itself.
442 wimlib_global_init() now, by default, attempts to acquire additional
443 privileges on Windows, so library clients need not do this.
445 This update bumps the shared library version number up to 9, since it is
446 not binary compatibible with previous releases.
449 Fixed bug in `wimlib-imagex export' that made it impossible to export an
450 image from a WIM that is readonly at the filesystem level.
452 Return error code rather than segfaulting when trying to list files from
453 a non-first part of a split WIM.
455 Joining a WIM will now preserve the RP_FIX and READONLY flags.
458 On Windows, paths given to wimlib-imagex are now treated case
461 Improved behavior regarding invalid filenames; in particular, on
462 Windows, wimlib-imagex will, when extracting, now omit (with an option
463 to override this default) filenames differing only in case, or filenames
464 containing characters not valid on Windows.
466 On Windows, wimlib now supports capturing and extracting long paths
467 (longer than the so-called MAX_PATH).
469 On Windows, `wimlib-imagex update' now acquires proper privileges when
470 running as an Administrator.
472 `wimlib-imagex update' will now complain if no image is specified when
473 trying to update a multi-image WIM.
475 `wimlib-imagex update' now supports specifying a single update command
476 directly on the command line using the --command option.
478 wimlib-imagex will now choose different units for progress messages,
479 depending on the amount of data that needs to be processed.
481 `wimlib-imagex append' will now generate a unique WIM image name if no
482 name is specified and the defaulted name already exists in the WIM.
484 wimlib now allows you to create unnamed WIM images, which can then only
485 be referred to by index.
487 wimlib now allows you to explicitly declare you want write access to a
488 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
491 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
494 Progress callbacks have been added to wimlib's wimlib_update_image()
497 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
498 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
501 NTFS-3g capture now only warns about two conditions previously treated
504 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
507 wimlib now correctly detects and returns an error when reading a WIM
508 image with a cyclic directory structure. (Fun fact: such a WIM will
509 crash Microsoft's software.)
512 Added new "extract" and "update" subcommands to wimlib-imagex, along
513 with associated APIs in the library. These commands are intended mainly
514 for Windows use but can be used on UNIX as well.
516 Many documentation improvements.
518 Fixed a bug in the Windows build where relative symbolic links were not
519 captured in reparse-point fixup mode.
521 Fixed a bug in the Windows build where file handles were left open to
522 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
524 Fixed a bug in the Windows build of wimlib-imagex where globbing
525 split-WIM parts could cause the program to crash.
527 Fixed a bug where the creation time of WIM images would be shown instead
528 of the last modification time.
530 With the Windows build it is now possible to restore a WIM containing
531 symbolic links as a non-Administrator; however you will receive warnings
532 about not being able to extract the symbolic links.
535 Capturing a WIM image should now be significantly faster in most cases
536 due to improved use of the operating system's cache and avoiding reading
537 files twice whenever possible.
539 The Windows build should now work on Windows XP.
541 The Windows build now supports capturing and restoring hidden,
542 compressed, sparse, and encrypted files.
544 The Windows build now supports capturing and applying WIM images from
545 filesystems other than NTFS (with some reduced functionality).
547 The Windows build now extracts short names correctly.
549 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
550 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
551 capture' and `wimlib-imagex apply'.
553 The performance of splitting and joining WIMs should be slightly
556 The LZX and XPRESS compression and decompression functions are now
557 exported from the library.
560 Improvements and bugfixes for the Windows build.
562 Added --strict-acls options.
564 Fixed the way that wimlib determines the order of images in the WIM.
567 Since wimlib can now be used on Windows, wimlib's implementation of
568 ImageX has been renamed to wimlib-imagex to avoid confusion with
569 Microsoft's implementation of ImageX, which would have the same file
570 name ("imagex.exe"). If you really don't like this you can pass the
571 --with-imagex-progname option to `configure' to choose a different name,
572 or even simply rename the binary yourself (but the former way will
573 configure the man pages to use the chosen name).
575 Various bugs fixed in the Windows build. Mainly to do with capturing
576 and restoring alternate data streams correctly in weird cases, and
577 requesting the correct privileges when opening files. Also added the
578 --noacls options to wimlib-imagex capture, append, and apply.
580 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
581 dynamically loaded, so this may make the library compatible with Windows
582 XP (however, there may still be other problems).
585 Added experimental support for native Windows builds. Binaries can be
586 downloaded from the SourceForge page.
588 --source-list option added to `imagex capture' and `imagex append'.
590 Better support for different character encodings.
593 Storing UNIX file owners, groups, and modes in WIM images is now
594 possible using `imagex capture' with the --unix-data flag.
596 Minor bug fixes and documentation fixes.
599 NTFS capture: Fixed capturing duplicate reparse points.
601 NTFS capture: Capture first unnamed stream if there are more than one
602 (print warning instead of error).
604 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
607 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
610 Update to work with ntfs-3g version 2013.1.13.
613 Fixed truncating file to shorter but non-zero length on read-write
616 Various code cleanups and minor documentation fixes.
619 LZX and XPRESS decompression have received some additional optimizations
620 and should now be even faster. (Although, they were already pretty
621 fast--- much faster than typical I/O speeds.)
623 Fixed a bug introduced in v1.2.1 that would cause a directory tree
624 containing hard links to be captured incorrectly in some cases.
627 By default, unmounting a read-write mounted WIM with 'imagex unmount
628 --commit' will now change the WIM in-place without needing to write the
629 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
632 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
633 for a response from the daemon servicing the mounted WIM. Instead,
634 every second 'imagex unmount' will check if the daemon is still alive,
635 and keep waiting if so, otherwise terminate with an error.
637 'imagex unmount --commit' on a read-write mounted WIM will now print
638 progress information regarding the writing of new or modified streams
639 the WIM, just like when capturing or appending a WIM.
641 A small change has been made to XPRESS compression and it should improve
642 the compression ratio slightly.
644 A change was made that may improve performance slightly when applying a
645 WIM image to a NTFS volume.
647 Microsoft has managed to introduce even more bugs into their software,
648 and now the WIMs for Windows 8 have incorrect (too low) reference counts
649 for some streams. This is unsafe because such streams can be removed
650 when they are in actuality still referenced in the WIM (perhaps by a
651 different image). wimlib will now work around this problem by fixing
652 the stream reference counts. This is only done when wimlib_delete_image() is
653 called ('imagex delete') or when wimlib_mount_image() is called with
654 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
655 requires reading the metadata for all images in the WIM, so this will
656 make these operations noticably slower on WIMs with multiple images.
658 Various other bugfixes.
661 Appending images to a WIM is now be done by default without re-building
662 the whole WIM. Use the --rebuild flag to get the old behavior (which
663 was to re-build the entire WIM when a new image is appended).
665 A new command `imagex optimize' is now available to manually re-build a
666 WIM that has wasted space due to repeated appends.
668 Progress information has been improved, and now arbitrary callback
669 functions can be used to show the progress of a WIM operation.
671 A possible bug with changing the bootable image of a WIM was fixed.
673 Some advisory locking is now done to prevent two processes from
674 modifying a WIM at the same time (but only in some cases). For example,
675 you cannot mount two images from a WIM read-write at the same time.
677 Some functions have been reorganized:
678 * wimlib_mount() renamed to wimlib_mount_image().
679 * wimlib_unmount() renamed to wimlib_unmount_image().
680 * wimlib_overwrite_xml_and_header() removed as
681 wimlib_overwrite() suffices now.
682 * wimlib_apply_image_to_ntfs_volume() removed as
683 wimlib_extract_image() suffices now.
684 * wimlib_add_image_from_ntfs_volume() removed as
685 * wimlib_add_image() suffices now.
687 Previously, the soname of libwim.so has been 0.0.0, despite many
688 interface changes. The soname is now updated to 1.0.0 and will now be
689 updated each release.
692 Resources will now be compressed using multiple threads by default.
693 (This applies to `imagex capture', `imagex append', and `imagex
696 Some performance improvements in mounted WIMs.
698 More progress information is shown when capturing a WIM.
701 Lots of minor fixes, code cleanups, and some documentation updates.
702 Nothing in particular is really noteworthy.
705 LZX and XPRESS compression improvements.
707 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
708 Link Bytes of the WIM.
711 Fixed bug when capturing NTFS file with multiple named data streams.
713 Internally, we are now using inode structures, even though these don't
714 appear literally in the WIM file. This simplifies some of the code
715 (mainly for WIM mounting) and likely fixed a few problems, although it
719 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
723 Enough changes to call it version 1.0.0!
725 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
726 to a NTFS volume, is now supported.
728 Hard links and symbolic links have much improved support. They are
729 supported for WIM capture, WIM application, and mounted WIMs (you can
730 even make them on read-write mounted WIMs).
732 Alternate data streams are now supported on mounted WIMs through an
733 xattr or a Windows-style stream interface. Also they are supported when
734 capturing a WIM from NTFS or applying a WIM to NTFS.
736 Split WIMs are better supported. You may now apply an image directly
737 from a split WIM, mount an image from a split WIM read-only, or export
738 an image from a split WIM.
740 Using a capture configuration file is now supported (but not fully yet).
742 SHA1 message digests are checked in more places, so we can make sure
743 applied and captured data is correct.
745 Man pages have been updated and consolidated.
748 Fixed segfault when unmounting read-only WIM.
751 Support for joining and splitting WIMs.
752 Also, security data is now preserved by default.
755 Can now build with older gcc and system headers, like on CentOS 5.
758 Fixed bug that made it impossible to overwrite files in read-write
762 Write byte-order mark before WIM XML data. (imagex.exe requires this to
