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