2 Fixed a bug: on 32-bit systems, the library would enter an infinite loop
3 if WIM image metadata was malformed in a very specific way.
5 Windows symbolic links and junctions in mounted WIM images are now
6 automatically rewritten to be valid in the mounted location.
9 Fixed a bug in the LZX decompressor: malicious input data could cause
10 out of bounds writes to memory (since wimlib v1.2.2).
12 The output of the 'wiminfo' command now consolidates various boolean
13 flags (such as "Relative path junction") into a single line.
15 A file can now have both an unnamed data stream ("file contents") and a
16 reparse point stream. Such files can exist as a result of the use of
17 certain Windows features, such as offline storage, including "OneDrive".
18 wimlib will now store and restore both streams on Windows as well as in
19 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
21 On Windows, named data streams of encrypted files are no longer stored
22 twice in WIM archives.
24 On Windows, named data streams are now correctly extracted to existing
25 "readonly" directories. Before, an error would be reported.
27 On Windows, it is now possible to do a "WIMBoot mode" extraction with
28 non-standalone WIMs such as delta WIMs.
30 On Windows, when doing an extraction in "WIMBoot mode", files larger
31 than 4 gigabytes are now never extracted as externally backed. This
32 works around a bug in Microsoft's "WOF" driver.
34 The '--enable-verify-compression' configure option has been removed. If
35 you want to verify a WIM file, use the 'wimverify' program.
37 The way the "file count", "directory count", "total bytes", and "hard
38 link bytes" image statistics (stored in the WIM XML data) is calculated
39 has been slightly changed.
41 In mounted WIM images, the disk usage provided for each file (st_blocks)
42 is now the compressed size rather than the uncompressed size.
44 The performance of the NTFS-3g and Windows capture modes has been
47 On UNIX-like systems, symbolic links whose targets contain the backslash
48 character are now handled correctly (losslessly).
51 Improved the LZX compressor. It is now 15-20% faster than before and
52 provides a slightly better compression ratio.
54 Improved the LZMS compressor. It now provides a compression ratio
55 slightly better than WIMGAPI while still being faster and using slightly
58 The compression chunk size in solid resources, e.g. when capturing or
59 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
60 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
61 better compression ratio and is the same value that WIMGAPI uses. The
62 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
63 lower than WIMGAPI's memory usage, but if it is too much, it is still
64 possible to choose a lower value, e.g. with the '--solid-chunk-size'
65 option to wimlib-imagex.
67 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
68 accept the 'K', 'M', and 'G' suffixes.
70 Files are now sorted by name extension when creating a solid WIM file.
72 Fixed various issues related to capture/apply of EFS-encrypted files on
75 The file list printed by 'wimdir' is now sorted by the platform-specific
76 case sensitivity setting, rather than always case sensitively. This
77 also affects the library function wimlib_iterate_dir_tree().
79 On Windows, some error and warning messages have been improved.
82 The Windows binary distribution no longer contains third party DLLs.
83 These dependencies are instead compiled directly into the libwim DLL.
85 Added more fixes for wimlib on non-x86 architectures such as ARM.
87 Extracting files to a Windows PE in-memory filesystem no longer fails if
88 the target files do not yet exist.
90 Improved the performance of XPRESS compression and LZMS decompression.
92 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
93 It will automatically be faster on newer Intel and AMD processors.
95 Removed the --with-imagex-progname and --enable-more-assertions
99 Fix for very slow export from solid WIM / ESD files.
101 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
103 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
104 may use this to treat some types of errors as non-fatal.
106 The library now permits making in-memory changes to a WIMStruct backed
107 by a read-only WIM file.
109 Fixes for "WIMBoot" extraction mode (Windows only):
111 When not using the WOF driver, extraction no longer fails if the
112 disk containing the WIM file has too many partitions.
114 When matching patterns in [PrepopulateList], all hard links of
115 each file are now considered.
117 The system registry files are now automatically treated as being
118 in [PrepopulateList].
120 Added a hack to try to work around an intermittent bug in
121 Microsoft's WOF (Windows Overlay Filesystem) driver.
124 Made more improvements to the XPRESS, LZX, and LZMS compressors.
126 A number of improvements to the Windows port:
128 Fixes for setting short filenames.
130 Faster "WIMBoot" extraction.
132 Updated and slimmed down the dependent DLLs.
134 ACL inheritence bits are now restored.
136 Mandatory integrity labels are now backed up and restored.
138 Added a workaround for an issue where in rare cases, wimlib could create
139 a compressed data stream that could not be read correctly by Windows
140 after an extraction in "WIMBoot" mode.
143 Added file count progress data for
144 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
145 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
147 Added support for testing file exclusions via the user-provided
150 Some documentation improvements.
152 Made some clarifications to the license text in the COPYING file.
155 Made more improvements to the XPRESS, LZX, and LZMS compressors.
157 The default compression mode for wimcapture is now LZX compression in
158 its default mode, which is the same as '--compress=maximum'.
160 You can now specify an optional integer compression level to the
161 '--compress' option; e.g. '--compress=lzx:75'.
163 Made a minor change to the LZMS compressor and decompressor to fix an
164 incompatibility with the Microsoft implementation. In the unlikely
165 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
166 earlier and a checksum error is reported when extracting files from it
167 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
170 Added 'verify' subcommand to wimlib-imagex.
172 Notable library changes:
174 Custom compressor parameters have been removed from the library
175 in favor of the simpler level-based API.
177 Decompressor parameters have been removed entirely.
179 Library users can now specify a custom file for warning and
180 error messages to be sent to, rather than the default of
183 New progress messages:
184 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
185 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
187 New function: wimlib_verify_wim().
190 Improved compression, decompression, and extraction performance.
192 Improved compatibility with version 3584 WIM / ESD files:
193 - Add support for reading and writing multiple solid blocks per
194 archive, which WIMGAPI/DISM can create when appending an image.
195 - Correctly create solid blocks larger than 4 GiB.
197 'add' commands passed to wimupdate will now replace existing
198 nondirectory files by default. Use the --no-replace option to get the
201 The license for the library now contains an exception that allows using
202 it under the LGPL. See the COPYING file for details.
204 In reparse-point fixup mode (the default for capture), symbolic links
205 and junctions that point outside the tree being captured are no longer
206 excluded from capture.
208 Added support for "WIMBoot" capture and extraction. See the
209 documentation for the new '--wimboot' option to wimcapture and wimapply
210 for more information.
212 On UNIX-like systems, you can now backup and restore device nodes, named
213 pipes, and sockets. In addition, 32-bit user and group IDs are now
216 The way that UNIX data is stored in WIM files has been changed. If you
217 captured any WIMs with the --unix-data option, to upgrade them you'll
218 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
219 re-capture them with --unix-data using this version.
221 wimlib now understands tagged metadata items, such as object IDs, that
222 can be stored in WIM directory entries.
224 Removed the --hardlink and --symlink options to wimapply, since I don't
225 think they are too useful and they got in the way of improving the code.
227 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
229 The 'mkwinpeimg' script now supports writing the ISO image to standard
232 The <ARCH> element in WIM XML data is now exported correctly.
234 On Windows, sparse file attributes are no longer set on extracted files.
235 Oddly enough, this actually saves disk space in some cases.
237 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
238 supported. Mounting WIM images now always requires extended attribute
239 support. Use --without-fuse to disable support for mounting WIM images;
240 this will also disable the need for extended attribute support.
242 Configuring with --enable-ssse3-sha1 now works correctly.
244 The shared library version has been bumped up. The main
245 incompatibilities are:
247 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
248 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
251 - User-provided progress functions are now registered using a
252 separate function, wimlib_register_progress_function(). The
253 'progress_func' argument to many functions no longer exists.
255 - The return value from user-provided progress functions is now
258 - A context argument has been added to the prototype of
259 user-provided progress functions.
261 - 'struct wimlib_capture_config' has been removed. The library
262 now takes the path to the configuration file directly. This
263 affects wimlib_add_image(), wimlib_add_image_multisource(),
264 and wimlib_update_image(). However, a NULL value passed in
265 the argument retains the same meaning.
267 - Removed deprecated functions: some (de)compression functions,
268 wimlib_extract_files(), and wimlib_print_metadata().
270 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
271 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
272 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
274 - Removed some progress messages:
275 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
276 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
277 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
280 - Removed some error codes. Numbering stays the same.
282 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
283 WIMLIB_UNMOUNT_FLAG_FORCE.
285 - WIM paths passed to progress functions now have a leading
289 Case-insensitive comparisons of strings (e.g. filenames) containing
290 UTF-16 codepoints above 32767 are now done correctly.
292 Fixed build failure on Mac OS X.
294 wimunmount now provides the '--new-image' option to cause changes to a
295 read-write mounted image to be committed as a new image rather than as
296 an update of the mounted image. (The corresponding new library flag is
297 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
299 The LZMS ("recovery") compression chunk size, or "dictionary size", may
300 now be up to 1 GiB (1,073,741,824 bytes).
302 The performance of LZX ("maximum") and LZMS ("recovery") compression
303 with large chunk sizes has been slightly improved.
306 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
307 decompressed correctly.
309 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
310 occurred in an unlikely case, and due to validity checks it did not
311 affect successfully created archives.
313 Fixed a minor compatibility issue with the LZMS compressor and
314 decompressor. This is *not* the default compression type and was only
315 introduced in v1.6.0. In the unlikely event that you created an
316 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
317 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
320 Memory usage for LZMS and LZX compression has been decreased.
322 wimextract now allows wildcard characters in paths specified on the
323 command line. Also, the '--strict-wildcards' option has been removed
324 and replaced with the inverse option '--nullglob'. See the
325 documentation for wimextract for more details and changes.
327 The wimlib_extract_files() function is now considered deprecated in
328 favor of wimlib_extract_paths().
330 Fixed more permissions problems when extracting files on Windows.
332 A new '--no-attributes' option has been added to wimapply and
333 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
335 The default chunk size is now set correctly when changing the
336 compression type of a WIM, for example with 'wimoptimize'.
338 The '--metadata' option to wiminfo has been replaced with the
339 '--detailed' option to wimdir.
341 In relevant wimlib-imagex commands, '--solid' may now be used as an
342 alias for '--pack-streams'.
345 Support for extracting and updating the new version 3584 WIMs has been
346 added. These WIMs typically pack many streams ("files") together into a
347 single compressed resource, thereby saving space. This degrades the
348 performance of random access (such as that which occurs on a mounted
349 image), but optimizations have been implemented for extraction. These
350 new WIM files also typically use a new compression format (LZMS), which
351 is similar to LZMA and can offer a better compression ratio than LZX.
352 These new WIM files can be created using `wimcapture' with
353 the '--compress=lzms --pack-streams' options. Note: this new WIM format
354 is used by the Windows 8 web downloader, but important segments of the
355 raw '.esd' files are encrypted, so wimlib will not be able to extract
356 such files until they are first decrypted.
358 wimlib now supports extracting files and directories from a WIM image
359 based on a "listfile" that itself contains the list of paths to extract.
360 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
361 and for the library itself, the new APIs are wimlib_extract_pathlist()
362 and wimlib_extract_paths(). Path globs containing wildcard characters
365 For searching WIM files, wimlib now has configurable case sensitivity.
366 The default on Windows is still case-insensitive and the default on
367 UNIX-like systems is still case-sensitive, but this can be overridden
368 on either platform through flags to wimlib_global_init(). For
369 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
370 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
373 Support for compression chunk sizes greater than the default of 32768
374 bytes has been added. A larger chunk size typically results in a better
375 compression ratio. However, the MS implementation is seemingly not
376 compatible with all chunk sizes, especially for LZX compression, so the
377 defaults remain unchanged, with the exception of the new LZMS-compressed
378 WIMs, which use a larger chunk size by default.
380 The compression/decompression API exported by wimlib has been changed.
381 Now one set of functions handles all supported compression formats.
383 `wimcapture' and `wimappend' will now display the progress of scanning
384 the directory tree to capture, in addition to the progress of writing
385 data to the WIM. The '--verbose' option no longer does anything. The
386 library API change for this is the addition of several members to
387 `struct wimlib_progress_info_scan' available to progress callbacks.
389 `mkwinpeimg' now correctly handles the '--start-script' option when the
390 start script is not in the working directory.
392 Sequential extraction, previously requested by using
393 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
394 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
395 behavior (extract in file order).
398 The new LZX compressor added in v1.5.2 has been improved and is now
399 enabled by default, except when `wimcapture' or `wimappend' is run
400 *without* the '--compress' option, in which case the faster LZX
401 compressor is used (the same as before). This behavior is reasonably
402 consistent with ImageX which actually uses "fast" (XPRESS) compression
403 by default. In those cases, use '--compress=maximum' to explicitly
404 capture a WIM image using the new (slower but better) LZX compressor.
406 The '--compress-slow' option still exists to `wimlib-imagex optimize',
407 but its new behavior is to tweak the new LZX compressor even more to
408 produce an even better compression ratio at the cost of more time spent
411 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
412 which recompresses the WIM file using the specified compression TYPE.
413 The new library API function used for this is
414 wimlib_set_output_compression_type().
416 Added the wimlib_get_xml_data() function to allow library clients to
417 easily retrieve the raw XML data from a WIM file if needed.
419 Fixed a bug that could cause an error code to be incorrectly returned
420 when writing XML data containing a <WINDOWS> element.
422 Mounted WIM images will now correctly show the default file stream even
423 if appears in the alternate data stream entries of the corresponding WIM
427 Added a new experimental LZX compressor which can be enabled by passing
428 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
429 optimize'. (The latter is only applicable if the WIM is already
430 LZX-compressed and the '--recompress' option is also given.) The
431 experimental compressor is much slower but compresses the data slightly
432 more --- currently usually to within a fraction of a percent of the
433 results from WIMGAPI/ImageX.
435 A workaround has been added for compatibility with versions of WinPE
436 that interpret alternate data stream entries in the boot WIM
439 An alignment bug that caused a crash in the LZX decompressor on some
442 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
443 the WIM header when restoring the previous state of a WIM it failed to
446 Added a workaround to avoid an access denied error on Windows when
447 replacing a WIM file that another process has opened.
450 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
451 needed to be handled.
453 A bug in the interpretation of negative IMAGE indices in the
454 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
455 `wimlib-imagex append' has been fixed.
457 A workaround has been added to successfully apply security descriptors
458 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
459 2013.1.13 or earlier.
461 `wimlib-imagex capture' can now accept the '--delta-from' option
465 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
466 to standard output and applying images from standard input, but they are
467 not compatible with Microsoft's software and are not created by default.
468 See the documentation for --pipable flag of `wimlib-imagex capture' for
471 To better support incremental backups, added support for declaring an
472 image as a modified form of another image. See the documentation for
473 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
476 Added supported for "delta" WIMs. See the documentation for the
477 '--delta-from' option of `wimlib-imagex capture'.
479 The library support for managing split WIMs has been changed to support
480 other arrangements, such as delta WIMs, and be easier to use. This
481 change is visible in `wimlib-imagex', which also can now accept the
482 '--ref' option multiple times, and also now supports "delta" WIMs as
485 wimlib now preserves WIM integrity tables by default, even if
486 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
487 behavior of `wimlib-imagex' whenever the WIM being operated on contains
488 an integrity table and the '--check' option is not specified.
490 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
491 (when --compress is not specified). This provides the best compression
492 ratio by default, which is usually what is desired, at a cost of some
495 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
496 is the command as in `wimlib-imagex COMMAND'; for example, it can be
497 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
498 appropriate hard links are created in UNIX installations of
499 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
500 batch files that emulate this behavior are generated.
502 Security descriptors are now extracted correctly on Windows.
504 Fixed archiving DOS names in NTFS-3g capture mode.
506 The extraction code has been rewritten and it will now be easier to
507 support new features on all supported backends (currently Win32, UNIX,
508 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
509 now supported on all backends, not just UNIX.
511 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
512 than the WAIK itself.
514 wimlib_global_init() now, by default, attempts to acquire additional
515 privileges on Windows, so library clients need not do this.
517 This update bumps the shared library version number up to 9, since it is
518 not binary compatibible with previous releases.
521 Fixed bug in `wimlib-imagex export' that made it impossible to export an
522 image from a WIM that is readonly at the filesystem level.
524 Return error code rather than segfaulting when trying to list files from
525 a non-first part of a split WIM.
527 Joining a WIM will now preserve the RP_FIX and READONLY flags.
530 On Windows, paths given to wimlib-imagex are now treated case
533 Improved behavior regarding invalid filenames; in particular, on
534 Windows, wimlib-imagex will, when extracting, now omit (with an option
535 to override this default) filenames differing only in case, or filenames
536 containing characters not valid on Windows.
538 On Windows, wimlib now supports capturing and extracting long paths
539 (longer than the so-called MAX_PATH).
541 On Windows, `wimlib-imagex update' now acquires proper privileges when
542 running as an Administrator.
544 `wimlib-imagex update' will now complain if no image is specified when
545 trying to update a multi-image WIM.
547 `wimlib-imagex update' now supports specifying a single update command
548 directly on the command line using the --command option.
550 wimlib-imagex will now choose different units for progress messages,
551 depending on the amount of data that needs to be processed.
553 `wimlib-imagex append' will now generate a unique WIM image name if no
554 name is specified and the defaulted name already exists in the WIM.
556 wimlib now allows you to create unnamed WIM images, which can then only
557 be referred to by index.
559 wimlib now allows you to explicitly declare you want write access to a
560 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
563 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
566 Progress callbacks have been added to wimlib's wimlib_update_image()
569 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
570 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
573 NTFS-3g capture now only warns about two conditions previously treated
576 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
579 wimlib now correctly detects and returns an error when reading a WIM
580 image with a cyclic directory structure. (Fun fact: such a WIM will
581 crash Microsoft's software.)
584 Added new "extract" and "update" subcommands to wimlib-imagex, along
585 with associated APIs in the library. These commands are intended mainly
586 for Windows use but can be used on UNIX as well.
588 Many documentation improvements.
590 Fixed a bug in the Windows build where relative symbolic links were not
591 captured in reparse-point fixup mode.
593 Fixed a bug in the Windows build where file handles were left open to
594 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
596 Fixed a bug in the Windows build of wimlib-imagex where globbing
597 split-WIM parts could cause the program to crash.
599 Fixed a bug where the creation time of WIM images would be shown instead
600 of the last modification time.
602 With the Windows build it is now possible to restore a WIM containing
603 symbolic links as a non-Administrator; however you will receive warnings
604 about not being able to extract the symbolic links.
607 Capturing a WIM image should now be significantly faster in most cases
608 due to improved use of the operating system's cache and avoiding reading
609 files twice whenever possible.
611 The Windows build should now work on Windows XP.
613 The Windows build now supports capturing and restoring hidden,
614 compressed, sparse, and encrypted files.
616 The Windows build now supports capturing and applying WIM images from
617 filesystems other than NTFS (with some reduced functionality).
619 The Windows build now extracts short names correctly.
621 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
622 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
623 capture' and `wimlib-imagex apply'.
625 The performance of splitting and joining WIMs should be slightly
628 The LZX and XPRESS compression and decompression functions are now
629 exported from the library.
632 Improvements and bugfixes for the Windows build.
634 Added --strict-acls options.
636 Fixed the way that wimlib determines the order of images in the WIM.
639 Since wimlib can now be used on Windows, wimlib's implementation of
640 ImageX has been renamed to wimlib-imagex to avoid confusion with
641 Microsoft's implementation of ImageX, which would have the same file
642 name ("imagex.exe"). If you really don't like this you can pass the
643 --with-imagex-progname option to `configure' to choose a different name,
644 or even simply rename the binary yourself (but the former way will
645 configure the man pages to use the chosen name).
647 Various bugs fixed in the Windows build. Mainly to do with capturing
648 and restoring alternate data streams correctly in weird cases, and
649 requesting the correct privileges when opening files. Also added the
650 --noacls options to wimlib-imagex capture, append, and apply.
652 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
653 dynamically loaded, so this may make the library compatible with Windows
654 XP (however, there may still be other problems).
657 Added experimental support for native Windows builds. Binaries can be
658 downloaded from the SourceForge page.
660 --source-list option added to `imagex capture' and `imagex append'.
662 Better support for different character encodings.
665 Storing UNIX file owners, groups, and modes in WIM images is now
666 possible using `imagex capture' with the --unix-data flag.
668 Minor bug fixes and documentation fixes.
671 NTFS capture: Fixed capturing duplicate reparse points.
673 NTFS capture: Capture first unnamed stream if there are more than one
674 (print warning instead of error).
676 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
679 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
682 Update to work with ntfs-3g version 2013.1.13.
685 Fixed truncating file to shorter but non-zero length on read-write
688 Various code cleanups and minor documentation fixes.
691 LZX and XPRESS decompression have received some additional optimizations
692 and should now be even faster. (Although, they were already pretty
693 fast--- much faster than typical I/O speeds.)
695 Fixed a bug introduced in v1.2.1 that would cause a directory tree
696 containing hard links to be captured incorrectly in some cases.
699 By default, unmounting a read-write mounted WIM with 'imagex unmount
700 --commit' will now change the WIM in-place without needing to write the
701 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
704 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
705 for a response from the daemon servicing the mounted WIM. Instead,
706 every second 'imagex unmount' will check if the daemon is still alive,
707 and keep waiting if so, otherwise terminate with an error.
709 'imagex unmount --commit' on a read-write mounted WIM will now print
710 progress information regarding the writing of new or modified streams
711 the WIM, just like when capturing or appending a WIM.
713 A small change has been made to XPRESS compression and it should improve
714 the compression ratio slightly.
716 A change was made that may improve performance slightly when applying a
717 WIM image to a NTFS volume.
719 Microsoft has managed to introduce even more bugs into their software,
720 and now the WIMs for Windows 8 have incorrect (too low) reference counts
721 for some streams. This is unsafe because such streams can be removed
722 when they are in actuality still referenced in the WIM (perhaps by a
723 different image). wimlib will now work around this problem by fixing
724 the stream reference counts. This is only done when wimlib_delete_image() is
725 called ('imagex delete') or when wimlib_mount_image() is called with
726 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
727 requires reading the metadata for all images in the WIM, so this will
728 make these operations noticably slower on WIMs with multiple images.
730 Various other bugfixes.
733 Appending images to a WIM is now be done by default without re-building
734 the whole WIM. Use the --rebuild flag to get the old behavior (which
735 was to re-build the entire WIM when a new image is appended).
737 A new command `imagex optimize' is now available to manually re-build a
738 WIM that has wasted space due to repeated appends.
740 Progress information has been improved, and now arbitrary callback
741 functions can be used to show the progress of a WIM operation.
743 A possible bug with changing the bootable image of a WIM was fixed.
745 Some advisory locking is now done to prevent two processes from
746 modifying a WIM at the same time (but only in some cases). For example,
747 you cannot mount two images from a WIM read-write at the same time.
749 Some functions have been reorganized:
750 * wimlib_mount() renamed to wimlib_mount_image().
751 * wimlib_unmount() renamed to wimlib_unmount_image().
752 * wimlib_overwrite_xml_and_header() removed as
753 wimlib_overwrite() suffices now.
754 * wimlib_apply_image_to_ntfs_volume() removed as
755 wimlib_extract_image() suffices now.
756 * wimlib_add_image_from_ntfs_volume() removed as
757 * wimlib_add_image() suffices now.
759 Previously, the soname of libwim.so has been 0.0.0, despite many
760 interface changes. The soname is now updated to 1.0.0 and will now be
761 updated each release.
764 Resources will now be compressed using multiple threads by default.
765 (This applies to `imagex capture', `imagex append', and `imagex
768 Some performance improvements in mounted WIMs.
770 More progress information is shown when capturing a WIM.
773 Lots of minor fixes, code cleanups, and some documentation updates.
774 Nothing in particular is really noteworthy.
777 LZX and XPRESS compression improvements.
779 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
780 Link Bytes of the WIM.
783 Fixed bug when capturing NTFS file with multiple named data streams.
785 Internally, we are now using inode structures, even though these don't
786 appear literally in the WIM file. This simplifies some of the code
787 (mainly for WIM mounting) and likely fixed a few problems, although it
791 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
795 Enough changes to call it version 1.0.0!
797 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
798 to a NTFS volume, is now supported.
800 Hard links and symbolic links have much improved support. They are
801 supported for WIM capture, WIM application, and mounted WIMs (you can
802 even make them on read-write mounted WIMs).
804 Alternate data streams are now supported on mounted WIMs through an
805 xattr or a Windows-style stream interface. Also they are supported when
806 capturing a WIM from NTFS or applying a WIM to NTFS.
808 Split WIMs are better supported. You may now apply an image directly
809 from a split WIM, mount an image from a split WIM read-only, or export
810 an image from a split WIM.
812 Using a capture configuration file is now supported (but not fully yet).
814 SHA1 message digests are checked in more places, so we can make sure
815 applied and captured data is correct.
817 Man pages have been updated and consolidated.
820 Fixed segfault when unmounting read-only WIM.
823 Support for joining and splitting WIMs.
824 Also, security data is now preserved by default.
827 Can now build with older gcc and system headers, like on CentOS 5.
830 Fixed bug that made it impossible to overwrite files in read-write
834 Write byte-order mark before WIM XML data. (imagex.exe requires this to
