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().
9 Fixed various issues related to capture/apply of EFS-encrypted files on
13 The Windows binary distribution no longer contains third party DLLs.
14 These dependencies are instead compiled directly into the libwim DLL.
16 Added more fixes for wimlib on non-x86 architectures such as ARM.
18 Extracting files to a Windows PE in-memory filesystem no longer fails if
19 the target files do not yet exist.
21 Improved the performance of XPRESS compression and LZMS decompression.
23 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
24 It will automatically be faster on newer Intel and AMD processors.
26 Removed the --with-imagex-progname and --enable-more-assertions
30 Fix for very slow export from solid WIM / ESD files.
32 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
34 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
35 may use this to treat some types of errors as non-fatal.
37 The library now permits making in-memory changes to a WIMStruct backed
38 by a read-only WIM file.
40 Fixes for "WIMBoot" extraction mode (Windows only):
42 When not using the WOF driver, extraction no longer fails if the
43 disk containing the WIM file has too many partitions.
45 When matching patterns in [PrepopulateList], all hard links of
46 each file are now considered.
48 The system registry files are now automatically treated as being
51 Added a hack to try to work around an intermittent bug in
52 Microsoft's WOF (Windows Overlay Filesystem) driver.
55 Made more improvements to the XPRESS, LZX, and LZMS compressors.
57 A number of improvements to the Windows port:
59 Fixes for setting short filenames.
61 Faster "WIMBoot" extraction.
63 Updated and slimmed down the dependent DLLs.
65 ACL inheritence bits are now restored.
67 Mandatory integrity labels are now backed up and restored.
69 Added a workaround for an issue where in rare cases, wimlib could create
70 a compressed data stream that could not be read correctly by Windows
71 after an extraction in "WIMBoot" mode.
74 Added file count progress data for
75 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
76 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
78 Added support for testing file exclusions via the user-provided
81 Some documentation improvements.
83 Made some clarifications to the license text in the COPYING file.
86 Made more improvements to the XPRESS, LZX, and LZMS compressors.
88 The default compression mode for wimcapture is now LZX compression in
89 its default mode, which is the same as '--compress=maximum'.
91 You can now specify an optional integer compression level to the
92 '--compress' option; e.g. '--compress=lzx:75'.
94 Made a minor change to the LZMS compressor and decompressor to fix an
95 incompatibility with the Microsoft implementation. In the unlikely
96 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
97 earlier and a checksum error is reported when extracting files from it
98 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
101 Added 'verify' subcommand to wimlib-imagex.
103 Notable library changes:
105 Custom compressor parameters have been removed from the library
106 in favor of the simpler level-based API.
108 Decompressor parameters have been removed entirely.
110 Library users can now specify a custom file for warning and
111 error messages to be sent to, rather than the default of
114 New progress messages:
115 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
116 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
118 New function: wimlib_verify_wim().
121 Improved compression, decompression, and extraction performance.
123 Improved compatibility with version 3584 WIM / ESD files:
124 - Add support for reading and writing multiple solid blocks per
125 archive, which WIMGAPI/DISM can create when appending an image.
126 - Correctly create solid blocks larger than 4 GiB.
128 'add' commands passed to wimupdate will now replace existing
129 nondirectory files by default. Use the --no-replace option to get the
132 The license for the library now contains an exception that allows using
133 it under the LGPL. See the COPYING file for details.
135 In reparse-point fixup mode (the default for capture), symbolic links
136 and junctions that point outside the tree being captured are no longer
137 excluded from capture.
139 Added support for "WIMBoot" capture and extraction. See the
140 documentation for the new '--wimboot' option to wimcapture and wimapply
141 for more information.
143 On UNIX-like systems, you can now backup and restore device nodes, named
144 pipes, and sockets. In addition, 32-bit user and group IDs are now
147 The way that UNIX data is stored in WIM files has been changed. If you
148 captured any WIMs with the --unix-data option, to upgrade them you'll
149 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
150 re-capture them with --unix-data using this version.
152 wimlib now understands tagged metadata items, such as object IDs, that
153 can be stored in WIM directory entries.
155 Removed the --hardlink and --symlink options to wimapply, since I don't
156 think they are too useful and they got in the way of improving the code.
158 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
160 The 'mkwinpeimg' script now supports writing the ISO image to standard
163 The <ARCH> element in WIM XML data is now exported correctly.
165 On Windows, sparse file attributes are no longer set on extracted files.
166 Oddly enough, this actually saves disk space in some cases.
168 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
169 supported. Mounting WIM images now always requires extended attribute
170 support. Use --without-fuse to disable support for mounting WIM images;
171 this will also disable the need for extended attribute support.
173 Configuring with --enable-ssse3-sha1 now works correctly.
175 The shared library version has been bumped up. The main
176 incompatibilities are:
178 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
179 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
182 - User-provided progress functions are now registered using a
183 separate function, wimlib_register_progress_function(). The
184 'progress_func' argument to many functions no longer exists.
186 - The return value from user-provided progress functions is now
189 - A context argument has been added to the prototype of
190 user-provided progress functions.
192 - 'struct wimlib_capture_config' has been removed. The library
193 now takes the path to the configuration file directly. This
194 affects wimlib_add_image(), wimlib_add_image_multisource(),
195 and wimlib_update_image(). However, a NULL value passed in
196 the argument retains the same meaning.
198 - Removed deprecated functions: some (de)compression functions,
199 wimlib_extract_files(), and wimlib_print_metadata().
201 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
202 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
203 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
205 - Removed some progress messages:
206 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
207 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
208 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
211 - Removed some error codes. Numbering stays the same.
213 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
214 WIMLIB_UNMOUNT_FLAG_FORCE.
216 - WIM paths passed to progress functions now have a leading
220 Case-insensitive comparisons of strings (e.g. filenames) containing
221 UTF-16 codepoints above 32767 are now done correctly.
223 Fixed build failure on Mac OS X.
225 wimunmount now provides the '--new-image' option to cause changes to a
226 read-write mounted image to be committed as a new image rather than as
227 an update of the mounted image. (The corresponding new library flag is
228 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
230 The LZMS ("recovery") compression chunk size, or "dictionary size", may
231 now be up to 1 GiB (1,073,741,824 bytes).
233 The performance of LZX ("maximum") and LZMS ("recovery") compression
234 with large chunk sizes has been slightly improved.
237 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
238 decompressed correctly.
240 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
241 occurred in an unlikely case, and due to validity checks it did not
242 affect successfully created archives.
244 Fixed a minor compatibility issue with the LZMS compressor and
245 decompressor. This is *not* the default compression type and was only
246 introduced in v1.6.0. In the unlikely event that you created an
247 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
248 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
251 Memory usage for LZMS and LZX compression has been decreased.
253 wimextract now allows wildcard characters in paths specified on the
254 command line. Also, the '--strict-wildcards' option has been removed
255 and replaced with the inverse option '--nullglob'. See the
256 documentation for wimextract for more details and changes.
258 The wimlib_extract_files() function is now considered deprecated in
259 favor of wimlib_extract_paths().
261 Fixed more permissions problems when extracting files on Windows.
263 A new '--no-attributes' option has been added to wimapply and
264 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
266 The default chunk size is now set correctly when changing the
267 compression type of a WIM, for example with 'wimoptimize'.
269 The '--metadata' option to wiminfo has been replaced with the
270 '--detailed' option to wimdir.
272 In relevant wimlib-imagex commands, '--solid' may now be used as an
273 alias for '--pack-streams'.
276 Support for extracting and updating the new version 3584 WIMs has been
277 added. These WIMs typically pack many streams ("files") together into a
278 single compressed resource, thereby saving space. This degrades the
279 performance of random access (such as that which occurs on a mounted
280 image), but optimizations have been implemented for extraction. These
281 new WIM files also typically use a new compression format (LZMS), which
282 is similar to LZMA and can offer a better compression ratio than LZX.
283 These new WIM files can be created using `wimcapture' with
284 the '--compress=lzms --pack-streams' options. Note: this new WIM format
285 is used by the Windows 8 web downloader, but important segments of the
286 raw '.esd' files are encrypted, so wimlib will not be able to extract
287 such files until they are first decrypted.
289 wimlib now supports extracting files and directories from a WIM image
290 based on a "listfile" that itself contains the list of paths to extract.
291 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
292 and for the library itself, the new APIs are wimlib_extract_pathlist()
293 and wimlib_extract_paths(). Path globs containing wildcard characters
296 For searching WIM files, wimlib now has configurable case sensitivity.
297 The default on Windows is still case-insensitive and the default on
298 UNIX-like systems is still case-sensitive, but this can be overridden
299 on either platform through flags to wimlib_global_init(). For
300 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
301 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
304 Support for compression chunk sizes greater than the default of 32768
305 bytes has been added. A larger chunk size typically results in a better
306 compression ratio. However, the MS implementation is seemingly not
307 compatible with all chunk sizes, especially for LZX compression, so the
308 defaults remain unchanged, with the exception of the new LZMS-compressed
309 WIMs, which use a larger chunk size by default.
311 The compression/decompression API exported by wimlib has been changed.
312 Now one set of functions handles all supported compression formats.
314 `wimcapture' and `wimappend' will now display the progress of scanning
315 the directory tree to capture, in addition to the progress of writing
316 data to the WIM. The '--verbose' option no longer does anything. The
317 library API change for this is the addition of several members to
318 `struct wimlib_progress_info_scan' available to progress callbacks.
320 `mkwinpeimg' now correctly handles the '--start-script' option when the
321 start script is not in the working directory.
323 Sequential extraction, previously requested by using
324 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
325 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
326 behavior (extract in file order).
329 The new LZX compressor added in v1.5.2 has been improved and is now
330 enabled by default, except when `wimcapture' or `wimappend' is run
331 *without* the '--compress' option, in which case the faster LZX
332 compressor is used (the same as before). This behavior is reasonably
333 consistent with ImageX which actually uses "fast" (XPRESS) compression
334 by default. In those cases, use '--compress=maximum' to explicitly
335 capture a WIM image using the new (slower but better) LZX compressor.
337 The '--compress-slow' option still exists to `wimlib-imagex optimize',
338 but its new behavior is to tweak the new LZX compressor even more to
339 produce an even better compression ratio at the cost of more time spent
342 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
343 which recompresses the WIM file using the specified compression TYPE.
344 The new library API function used for this is
345 wimlib_set_output_compression_type().
347 Added the wimlib_get_xml_data() function to allow library clients to
348 easily retrieve the raw XML data from a WIM file if needed.
350 Fixed a bug that could cause an error code to be incorrectly returned
351 when writing XML data containing a <WINDOWS> element.
353 Mounted WIM images will now correctly show the default file stream even
354 if appears in the alternate data stream entries of the corresponding WIM
358 Added a new experimental LZX compressor which can be enabled by passing
359 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
360 optimize'. (The latter is only applicable if the WIM is already
361 LZX-compressed and the '--recompress' option is also given.) The
362 experimental compressor is much slower but compresses the data slightly
363 more --- currently usually to within a fraction of a percent of the
364 results from WIMGAPI/ImageX.
366 A workaround has been added for compatibility with versions of WinPE
367 that interpret alternate data stream entries in the boot WIM
370 An alignment bug that caused a crash in the LZX decompressor on some
373 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
374 the WIM header when restoring the previous state of a WIM it failed to
377 Added a workaround to avoid an access denied error on Windows when
378 replacing a WIM file that another process has opened.
381 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
382 needed to be handled.
384 A bug in the interpretation of negative IMAGE indices in the
385 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
386 `wimlib-imagex append' has been fixed.
388 A workaround has been added to successfully apply security descriptors
389 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
390 2013.1.13 or earlier.
392 `wimlib-imagex capture' can now accept the '--delta-from' option
396 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
397 to standard output and applying images from standard input, but they are
398 not compatible with Microsoft's software and are not created by default.
399 See the documentation for --pipable flag of `wimlib-imagex capture' for
402 To better support incremental backups, added support for declaring an
403 image as a modified form of another image. See the documentation for
404 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
407 Added supported for "delta" WIMs. See the documentation for the
408 '--delta-from' option of `wimlib-imagex capture'.
410 The library support for managing split WIMs has been changed to support
411 other arrangements, such as delta WIMs, and be easier to use. This
412 change is visible in `wimlib-imagex', which also can now accept the
413 '--ref' option multiple times, and also now supports "delta" WIMs as
416 wimlib now preserves WIM integrity tables by default, even if
417 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
418 behavior of `wimlib-imagex' whenever the WIM being operated on contains
419 an integrity table and the '--check' option is not specified.
421 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
422 (when --compress is not specified). This provides the best compression
423 ratio by default, which is usually what is desired, at a cost of some
426 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
427 is the command as in `wimlib-imagex COMMAND'; for example, it can be
428 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
429 appropriate hard links are created in UNIX installations of
430 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
431 batch files that emulate this behavior are generated.
433 Security descriptors are now extracted correctly on Windows.
435 Fixed archiving DOS names in NTFS-3g capture mode.
437 The extraction code has been rewritten and it will now be easier to
438 support new features on all supported backends (currently Win32, UNIX,
439 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
440 now supported on all backends, not just UNIX.
442 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
443 than the WAIK itself.
445 wimlib_global_init() now, by default, attempts to acquire additional
446 privileges on Windows, so library clients need not do this.
448 This update bumps the shared library version number up to 9, since it is
449 not binary compatibible with previous releases.
452 Fixed bug in `wimlib-imagex export' that made it impossible to export an
453 image from a WIM that is readonly at the filesystem level.
455 Return error code rather than segfaulting when trying to list files from
456 a non-first part of a split WIM.
458 Joining a WIM will now preserve the RP_FIX and READONLY flags.
461 On Windows, paths given to wimlib-imagex are now treated case
464 Improved behavior regarding invalid filenames; in particular, on
465 Windows, wimlib-imagex will, when extracting, now omit (with an option
466 to override this default) filenames differing only in case, or filenames
467 containing characters not valid on Windows.
469 On Windows, wimlib now supports capturing and extracting long paths
470 (longer than the so-called MAX_PATH).
472 On Windows, `wimlib-imagex update' now acquires proper privileges when
473 running as an Administrator.
475 `wimlib-imagex update' will now complain if no image is specified when
476 trying to update a multi-image WIM.
478 `wimlib-imagex update' now supports specifying a single update command
479 directly on the command line using the --command option.
481 wimlib-imagex will now choose different units for progress messages,
482 depending on the amount of data that needs to be processed.
484 `wimlib-imagex append' will now generate a unique WIM image name if no
485 name is specified and the defaulted name already exists in the WIM.
487 wimlib now allows you to create unnamed WIM images, which can then only
488 be referred to by index.
490 wimlib now allows you to explicitly declare you want write access to a
491 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
494 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
497 Progress callbacks have been added to wimlib's wimlib_update_image()
500 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
501 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
504 NTFS-3g capture now only warns about two conditions previously treated
507 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
510 wimlib now correctly detects and returns an error when reading a WIM
511 image with a cyclic directory structure. (Fun fact: such a WIM will
512 crash Microsoft's software.)
515 Added new "extract" and "update" subcommands to wimlib-imagex, along
516 with associated APIs in the library. These commands are intended mainly
517 for Windows use but can be used on UNIX as well.
519 Many documentation improvements.
521 Fixed a bug in the Windows build where relative symbolic links were not
522 captured in reparse-point fixup mode.
524 Fixed a bug in the Windows build where file handles were left open to
525 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
527 Fixed a bug in the Windows build of wimlib-imagex where globbing
528 split-WIM parts could cause the program to crash.
530 Fixed a bug where the creation time of WIM images would be shown instead
531 of the last modification time.
533 With the Windows build it is now possible to restore a WIM containing
534 symbolic links as a non-Administrator; however you will receive warnings
535 about not being able to extract the symbolic links.
538 Capturing a WIM image should now be significantly faster in most cases
539 due to improved use of the operating system's cache and avoiding reading
540 files twice whenever possible.
542 The Windows build should now work on Windows XP.
544 The Windows build now supports capturing and restoring hidden,
545 compressed, sparse, and encrypted files.
547 The Windows build now supports capturing and applying WIM images from
548 filesystems other than NTFS (with some reduced functionality).
550 The Windows build now extracts short names correctly.
552 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
553 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
554 capture' and `wimlib-imagex apply'.
556 The performance of splitting and joining WIMs should be slightly
559 The LZX and XPRESS compression and decompression functions are now
560 exported from the library.
563 Improvements and bugfixes for the Windows build.
565 Added --strict-acls options.
567 Fixed the way that wimlib determines the order of images in the WIM.
570 Since wimlib can now be used on Windows, wimlib's implementation of
571 ImageX has been renamed to wimlib-imagex to avoid confusion with
572 Microsoft's implementation of ImageX, which would have the same file
573 name ("imagex.exe"). If you really don't like this you can pass the
574 --with-imagex-progname option to `configure' to choose a different name,
575 or even simply rename the binary yourself (but the former way will
576 configure the man pages to use the chosen name).
578 Various bugs fixed in the Windows build. Mainly to do with capturing
579 and restoring alternate data streams correctly in weird cases, and
580 requesting the correct privileges when opening files. Also added the
581 --noacls options to wimlib-imagex capture, append, and apply.
583 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
584 dynamically loaded, so this may make the library compatible with Windows
585 XP (however, there may still be other problems).
588 Added experimental support for native Windows builds. Binaries can be
589 downloaded from the SourceForge page.
591 --source-list option added to `imagex capture' and `imagex append'.
593 Better support for different character encodings.
596 Storing UNIX file owners, groups, and modes in WIM images is now
597 possible using `imagex capture' with the --unix-data flag.
599 Minor bug fixes and documentation fixes.
602 NTFS capture: Fixed capturing duplicate reparse points.
604 NTFS capture: Capture first unnamed stream if there are more than one
605 (print warning instead of error).
607 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
610 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
613 Update to work with ntfs-3g version 2013.1.13.
616 Fixed truncating file to shorter but non-zero length on read-write
619 Various code cleanups and minor documentation fixes.
622 LZX and XPRESS decompression have received some additional optimizations
623 and should now be even faster. (Although, they were already pretty
624 fast--- much faster than typical I/O speeds.)
626 Fixed a bug introduced in v1.2.1 that would cause a directory tree
627 containing hard links to be captured incorrectly in some cases.
630 By default, unmounting a read-write mounted WIM with 'imagex unmount
631 --commit' will now change the WIM in-place without needing to write the
632 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
635 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
636 for a response from the daemon servicing the mounted WIM. Instead,
637 every second 'imagex unmount' will check if the daemon is still alive,
638 and keep waiting if so, otherwise terminate with an error.
640 'imagex unmount --commit' on a read-write mounted WIM will now print
641 progress information regarding the writing of new or modified streams
642 the WIM, just like when capturing or appending a WIM.
644 A small change has been made to XPRESS compression and it should improve
645 the compression ratio slightly.
647 A change was made that may improve performance slightly when applying a
648 WIM image to a NTFS volume.
650 Microsoft has managed to introduce even more bugs into their software,
651 and now the WIMs for Windows 8 have incorrect (too low) reference counts
652 for some streams. This is unsafe because such streams can be removed
653 when they are in actuality still referenced in the WIM (perhaps by a
654 different image). wimlib will now work around this problem by fixing
655 the stream reference counts. This is only done when wimlib_delete_image() is
656 called ('imagex delete') or when wimlib_mount_image() is called with
657 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
658 requires reading the metadata for all images in the WIM, so this will
659 make these operations noticably slower on WIMs with multiple images.
661 Various other bugfixes.
664 Appending images to a WIM is now be done by default without re-building
665 the whole WIM. Use the --rebuild flag to get the old behavior (which
666 was to re-build the entire WIM when a new image is appended).
668 A new command `imagex optimize' is now available to manually re-build a
669 WIM that has wasted space due to repeated appends.
671 Progress information has been improved, and now arbitrary callback
672 functions can be used to show the progress of a WIM operation.
674 A possible bug with changing the bootable image of a WIM was fixed.
676 Some advisory locking is now done to prevent two processes from
677 modifying a WIM at the same time (but only in some cases). For example,
678 you cannot mount two images from a WIM read-write at the same time.
680 Some functions have been reorganized:
681 * wimlib_mount() renamed to wimlib_mount_image().
682 * wimlib_unmount() renamed to wimlib_unmount_image().
683 * wimlib_overwrite_xml_and_header() removed as
684 wimlib_overwrite() suffices now.
685 * wimlib_apply_image_to_ntfs_volume() removed as
686 wimlib_extract_image() suffices now.
687 * wimlib_add_image_from_ntfs_volume() removed as
688 * wimlib_add_image() suffices now.
690 Previously, the soname of libwim.so has been 0.0.0, despite many
691 interface changes. The soname is now updated to 1.0.0 and will now be
692 updated each release.
695 Resources will now be compressed using multiple threads by default.
696 (This applies to `imagex capture', `imagex append', and `imagex
699 Some performance improvements in mounted WIMs.
701 More progress information is shown when capturing a WIM.
704 Lots of minor fixes, code cleanups, and some documentation updates.
705 Nothing in particular is really noteworthy.
708 LZX and XPRESS compression improvements.
710 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
711 Link Bytes of the WIM.
714 Fixed bug when capturing NTFS file with multiple named data streams.
716 Internally, we are now using inode structures, even though these don't
717 appear literally in the WIM file. This simplifies some of the code
718 (mainly for WIM mounting) and likely fixed a few problems, although it
722 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
726 Enough changes to call it version 1.0.0!
728 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
729 to a NTFS volume, is now supported.
731 Hard links and symbolic links have much improved support. They are
732 supported for WIM capture, WIM application, and mounted WIMs (you can
733 even make them on read-write mounted WIMs).
735 Alternate data streams are now supported on mounted WIMs through an
736 xattr or a Windows-style stream interface. Also they are supported when
737 capturing a WIM from NTFS or applying a WIM to NTFS.
739 Split WIMs are better supported. You may now apply an image directly
740 from a split WIM, mount an image from a split WIM read-only, or export
741 an image from a split WIM.
743 Using a capture configuration file is now supported (but not fully yet).
745 SHA1 message digests are checked in more places, so we can make sure
746 applied and captured data is correct.
748 Man pages have been updated and consolidated.
751 Fixed segfault when unmounting read-only WIM.
754 Support for joining and splitting WIMs.
755 Also, security data is now preserved by default.
758 Can now build with older gcc and system headers, like on CentOS 5.
761 Fixed bug that made it impossible to overwrite files in read-write
765 Write byte-order mark before WIM XML data. (imagex.exe requires this to
