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.
6 Fixed a bug in the LZX decompressor: malicious input data could cause
7 out of bounds writes to memory (since wimlib v1.2.2).
9 The output of the 'wiminfo' command now consolidates various boolean
10 flags (such as "Relative path junction") into a single line.
12 A file can now have both an unnamed data stream ("file contents") and a
13 reparse point stream. Such files can exist as a result of the use of
14 certain Windows features, such as offline storage, including "OneDrive".
15 wimlib will now store and restore both streams on Windows as well as in
16 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
18 On Windows, named data streams of encrypted files are no longer stored
19 twice in WIM archives.
21 On Windows, named data streams are now correctly extracted to existing
22 "readonly" directories. Before, an error would be reported.
24 On Windows, it is now possible to do a "WIMBoot mode" extraction with
25 non-standalone WIMs such as delta WIMs.
27 On Windows, when doing an extraction in "WIMBoot mode", files larger
28 than 4 gigabytes are now never extracted as externally backed. This
29 works around a bug in Microsoft's "WOF" driver.
31 The '--enable-verify-compression' configure option has been removed. If
32 you want to verify a WIM file, use the 'wimverify' program.
34 The way the "file count", "directory count", "total bytes", and "hard
35 link bytes" image statistics (stored in the WIM XML data) is calculated
36 has been slightly changed.
38 In mounted WIM images, the disk usage provided for each file (st_blocks)
39 is now the compressed size rather than the uncompressed size.
41 The performance of the NTFS-3g and Windows capture modes has been
44 On UNIX-like systems, symbolic links whose targets contain the backslash
45 character are now handled correctly (losslessly).
48 Improved the LZX compressor. It is now 15-20% faster than before and
49 provides a slightly better compression ratio.
51 Improved the LZMS compressor. It now provides a compression ratio
52 slightly better than WIMGAPI while still being faster and using slightly
55 The compression chunk size in solid resources, e.g. when capturing or
56 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
57 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
58 better compression ratio and is the same value that WIMGAPI uses. The
59 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
60 lower than WIMGAPI's memory usage, but if it is too much, it is still
61 possible to choose a lower value, e.g. with the '--solid-chunk-size'
62 option to wimlib-imagex.
64 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
65 accept the 'K', 'M', and 'G' suffixes.
67 Files are now sorted by name extension when creating a solid WIM file.
69 Fixed various issues related to capture/apply of EFS-encrypted files on
72 The file list printed by 'wimdir' is now sorted by the platform-specific
73 case sensitivity setting, rather than always case sensitively. This
74 also affects the library function wimlib_iterate_dir_tree().
76 On Windows, some error and warning messages have been improved.
79 The Windows binary distribution no longer contains third party DLLs.
80 These dependencies are instead compiled directly into the libwim DLL.
82 Added more fixes for wimlib on non-x86 architectures such as ARM.
84 Extracting files to a Windows PE in-memory filesystem no longer fails if
85 the target files do not yet exist.
87 Improved the performance of XPRESS compression and LZMS decompression.
89 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
90 It will automatically be faster on newer Intel and AMD processors.
92 Removed the --with-imagex-progname and --enable-more-assertions
96 Fix for very slow export from solid WIM / ESD files.
98 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
100 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
101 may use this to treat some types of errors as non-fatal.
103 The library now permits making in-memory changes to a WIMStruct backed
104 by a read-only WIM file.
106 Fixes for "WIMBoot" extraction mode (Windows only):
108 When not using the WOF driver, extraction no longer fails if the
109 disk containing the WIM file has too many partitions.
111 When matching patterns in [PrepopulateList], all hard links of
112 each file are now considered.
114 The system registry files are now automatically treated as being
115 in [PrepopulateList].
117 Added a hack to try to work around an intermittent bug in
118 Microsoft's WOF (Windows Overlay Filesystem) driver.
121 Made more improvements to the XPRESS, LZX, and LZMS compressors.
123 A number of improvements to the Windows port:
125 Fixes for setting short filenames.
127 Faster "WIMBoot" extraction.
129 Updated and slimmed down the dependent DLLs.
131 ACL inheritence bits are now restored.
133 Mandatory integrity labels are now backed up and restored.
135 Added a workaround for an issue where in rare cases, wimlib could create
136 a compressed data stream that could not be read correctly by Windows
137 after an extraction in "WIMBoot" mode.
140 Added file count progress data for
141 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
142 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
144 Added support for testing file exclusions via the user-provided
147 Some documentation improvements.
149 Made some clarifications to the license text in the COPYING file.
152 Made more improvements to the XPRESS, LZX, and LZMS compressors.
154 The default compression mode for wimcapture is now LZX compression in
155 its default mode, which is the same as '--compress=maximum'.
157 You can now specify an optional integer compression level to the
158 '--compress' option; e.g. '--compress=lzx:75'.
160 Made a minor change to the LZMS compressor and decompressor to fix an
161 incompatibility with the Microsoft implementation. In the unlikely
162 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
163 earlier and a checksum error is reported when extracting files from it
164 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
167 Added 'verify' subcommand to wimlib-imagex.
169 Notable library changes:
171 Custom compressor parameters have been removed from the library
172 in favor of the simpler level-based API.
174 Decompressor parameters have been removed entirely.
176 Library users can now specify a custom file for warning and
177 error messages to be sent to, rather than the default of
180 New progress messages:
181 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
182 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
184 New function: wimlib_verify_wim().
187 Improved compression, decompression, and extraction performance.
189 Improved compatibility with version 3584 WIM / ESD files:
190 - Add support for reading and writing multiple solid blocks per
191 archive, which WIMGAPI/DISM can create when appending an image.
192 - Correctly create solid blocks larger than 4 GiB.
194 'add' commands passed to wimupdate will now replace existing
195 nondirectory files by default. Use the --no-replace option to get the
198 The license for the library now contains an exception that allows using
199 it under the LGPL. See the COPYING file for details.
201 In reparse-point fixup mode (the default for capture), symbolic links
202 and junctions that point outside the tree being captured are no longer
203 excluded from capture.
205 Added support for "WIMBoot" capture and extraction. See the
206 documentation for the new '--wimboot' option to wimcapture and wimapply
207 for more information.
209 On UNIX-like systems, you can now backup and restore device nodes, named
210 pipes, and sockets. In addition, 32-bit user and group IDs are now
213 The way that UNIX data is stored in WIM files has been changed. If you
214 captured any WIMs with the --unix-data option, to upgrade them you'll
215 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
216 re-capture them with --unix-data using this version.
218 wimlib now understands tagged metadata items, such as object IDs, that
219 can be stored in WIM directory entries.
221 Removed the --hardlink and --symlink options to wimapply, since I don't
222 think they are too useful and they got in the way of improving the code.
224 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
226 The 'mkwinpeimg' script now supports writing the ISO image to standard
229 The <ARCH> element in WIM XML data is now exported correctly.
231 On Windows, sparse file attributes are no longer set on extracted files.
232 Oddly enough, this actually saves disk space in some cases.
234 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
235 supported. Mounting WIM images now always requires extended attribute
236 support. Use --without-fuse to disable support for mounting WIM images;
237 this will also disable the need for extended attribute support.
239 Configuring with --enable-ssse3-sha1 now works correctly.
241 The shared library version has been bumped up. The main
242 incompatibilities are:
244 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
245 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
248 - User-provided progress functions are now registered using a
249 separate function, wimlib_register_progress_function(). The
250 'progress_func' argument to many functions no longer exists.
252 - The return value from user-provided progress functions is now
255 - A context argument has been added to the prototype of
256 user-provided progress functions.
258 - 'struct wimlib_capture_config' has been removed. The library
259 now takes the path to the configuration file directly. This
260 affects wimlib_add_image(), wimlib_add_image_multisource(),
261 and wimlib_update_image(). However, a NULL value passed in
262 the argument retains the same meaning.
264 - Removed deprecated functions: some (de)compression functions,
265 wimlib_extract_files(), and wimlib_print_metadata().
267 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
268 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
269 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
271 - Removed some progress messages:
272 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
273 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
274 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
277 - Removed some error codes. Numbering stays the same.
279 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
280 WIMLIB_UNMOUNT_FLAG_FORCE.
282 - WIM paths passed to progress functions now have a leading
286 Case-insensitive comparisons of strings (e.g. filenames) containing
287 UTF-16 codepoints above 32767 are now done correctly.
289 Fixed build failure on Mac OS X.
291 wimunmount now provides the '--new-image' option to cause changes to a
292 read-write mounted image to be committed as a new image rather than as
293 an update of the mounted image. (The corresponding new library flag is
294 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
296 The LZMS ("recovery") compression chunk size, or "dictionary size", may
297 now be up to 1 GiB (1,073,741,824 bytes).
299 The performance of LZX ("maximum") and LZMS ("recovery") compression
300 with large chunk sizes has been slightly improved.
303 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
304 decompressed correctly.
306 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
307 occurred in an unlikely case, and due to validity checks it did not
308 affect successfully created archives.
310 Fixed a minor compatibility issue with the LZMS compressor and
311 decompressor. This is *not* the default compression type and was only
312 introduced in v1.6.0. In the unlikely event that you created an
313 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
314 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
317 Memory usage for LZMS and LZX compression has been decreased.
319 wimextract now allows wildcard characters in paths specified on the
320 command line. Also, the '--strict-wildcards' option has been removed
321 and replaced with the inverse option '--nullglob'. See the
322 documentation for wimextract for more details and changes.
324 The wimlib_extract_files() function is now considered deprecated in
325 favor of wimlib_extract_paths().
327 Fixed more permissions problems when extracting files on Windows.
329 A new '--no-attributes' option has been added to wimapply and
330 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
332 The default chunk size is now set correctly when changing the
333 compression type of a WIM, for example with 'wimoptimize'.
335 The '--metadata' option to wiminfo has been replaced with the
336 '--detailed' option to wimdir.
338 In relevant wimlib-imagex commands, '--solid' may now be used as an
339 alias for '--pack-streams'.
342 Support for extracting and updating the new version 3584 WIMs has been
343 added. These WIMs typically pack many streams ("files") together into a
344 single compressed resource, thereby saving space. This degrades the
345 performance of random access (such as that which occurs on a mounted
346 image), but optimizations have been implemented for extraction. These
347 new WIM files also typically use a new compression format (LZMS), which
348 is similar to LZMA and can offer a better compression ratio than LZX.
349 These new WIM files can be created using `wimcapture' with
350 the '--compress=lzms --pack-streams' options. Note: this new WIM format
351 is used by the Windows 8 web downloader, but important segments of the
352 raw '.esd' files are encrypted, so wimlib will not be able to extract
353 such files until they are first decrypted.
355 wimlib now supports extracting files and directories from a WIM image
356 based on a "listfile" that itself contains the list of paths to extract.
357 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
358 and for the library itself, the new APIs are wimlib_extract_pathlist()
359 and wimlib_extract_paths(). Path globs containing wildcard characters
362 For searching WIM files, wimlib now has configurable case sensitivity.
363 The default on Windows is still case-insensitive and the default on
364 UNIX-like systems is still case-sensitive, but this can be overridden
365 on either platform through flags to wimlib_global_init(). For
366 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
367 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
370 Support for compression chunk sizes greater than the default of 32768
371 bytes has been added. A larger chunk size typically results in a better
372 compression ratio. However, the MS implementation is seemingly not
373 compatible with all chunk sizes, especially for LZX compression, so the
374 defaults remain unchanged, with the exception of the new LZMS-compressed
375 WIMs, which use a larger chunk size by default.
377 The compression/decompression API exported by wimlib has been changed.
378 Now one set of functions handles all supported compression formats.
380 `wimcapture' and `wimappend' will now display the progress of scanning
381 the directory tree to capture, in addition to the progress of writing
382 data to the WIM. The '--verbose' option no longer does anything. The
383 library API change for this is the addition of several members to
384 `struct wimlib_progress_info_scan' available to progress callbacks.
386 `mkwinpeimg' now correctly handles the '--start-script' option when the
387 start script is not in the working directory.
389 Sequential extraction, previously requested by using
390 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
391 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
392 behavior (extract in file order).
395 The new LZX compressor added in v1.5.2 has been improved and is now
396 enabled by default, except when `wimcapture' or `wimappend' is run
397 *without* the '--compress' option, in which case the faster LZX
398 compressor is used (the same as before). This behavior is reasonably
399 consistent with ImageX which actually uses "fast" (XPRESS) compression
400 by default. In those cases, use '--compress=maximum' to explicitly
401 capture a WIM image using the new (slower but better) LZX compressor.
403 The '--compress-slow' option still exists to `wimlib-imagex optimize',
404 but its new behavior is to tweak the new LZX compressor even more to
405 produce an even better compression ratio at the cost of more time spent
408 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
409 which recompresses the WIM file using the specified compression TYPE.
410 The new library API function used for this is
411 wimlib_set_output_compression_type().
413 Added the wimlib_get_xml_data() function to allow library clients to
414 easily retrieve the raw XML data from a WIM file if needed.
416 Fixed a bug that could cause an error code to be incorrectly returned
417 when writing XML data containing a <WINDOWS> element.
419 Mounted WIM images will now correctly show the default file stream even
420 if appears in the alternate data stream entries of the corresponding WIM
424 Added a new experimental LZX compressor which can be enabled by passing
425 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
426 optimize'. (The latter is only applicable if the WIM is already
427 LZX-compressed and the '--recompress' option is also given.) The
428 experimental compressor is much slower but compresses the data slightly
429 more --- currently usually to within a fraction of a percent of the
430 results from WIMGAPI/ImageX.
432 A workaround has been added for compatibility with versions of WinPE
433 that interpret alternate data stream entries in the boot WIM
436 An alignment bug that caused a crash in the LZX decompressor on some
439 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
440 the WIM header when restoring the previous state of a WIM it failed to
443 Added a workaround to avoid an access denied error on Windows when
444 replacing a WIM file that another process has opened.
447 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
448 needed to be handled.
450 A bug in the interpretation of negative IMAGE indices in the
451 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
452 `wimlib-imagex append' has been fixed.
454 A workaround has been added to successfully apply security descriptors
455 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
456 2013.1.13 or earlier.
458 `wimlib-imagex capture' can now accept the '--delta-from' option
462 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
463 to standard output and applying images from standard input, but they are
464 not compatible with Microsoft's software and are not created by default.
465 See the documentation for --pipable flag of `wimlib-imagex capture' for
468 To better support incremental backups, added support for declaring an
469 image as a modified form of another image. See the documentation for
470 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
473 Added supported for "delta" WIMs. See the documentation for the
474 '--delta-from' option of `wimlib-imagex capture'.
476 The library support for managing split WIMs has been changed to support
477 other arrangements, such as delta WIMs, and be easier to use. This
478 change is visible in `wimlib-imagex', which also can now accept the
479 '--ref' option multiple times, and also now supports "delta" WIMs as
482 wimlib now preserves WIM integrity tables by default, even if
483 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
484 behavior of `wimlib-imagex' whenever the WIM being operated on contains
485 an integrity table and the '--check' option is not specified.
487 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
488 (when --compress is not specified). This provides the best compression
489 ratio by default, which is usually what is desired, at a cost of some
492 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
493 is the command as in `wimlib-imagex COMMAND'; for example, it can be
494 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
495 appropriate hard links are created in UNIX installations of
496 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
497 batch files that emulate this behavior are generated.
499 Security descriptors are now extracted correctly on Windows.
501 Fixed archiving DOS names in NTFS-3g capture mode.
503 The extraction code has been rewritten and it will now be easier to
504 support new features on all supported backends (currently Win32, UNIX,
505 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
506 now supported on all backends, not just UNIX.
508 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
509 than the WAIK itself.
511 wimlib_global_init() now, by default, attempts to acquire additional
512 privileges on Windows, so library clients need not do this.
514 This update bumps the shared library version number up to 9, since it is
515 not binary compatibible with previous releases.
518 Fixed bug in `wimlib-imagex export' that made it impossible to export an
519 image from a WIM that is readonly at the filesystem level.
521 Return error code rather than segfaulting when trying to list files from
522 a non-first part of a split WIM.
524 Joining a WIM will now preserve the RP_FIX and READONLY flags.
527 On Windows, paths given to wimlib-imagex are now treated case
530 Improved behavior regarding invalid filenames; in particular, on
531 Windows, wimlib-imagex will, when extracting, now omit (with an option
532 to override this default) filenames differing only in case, or filenames
533 containing characters not valid on Windows.
535 On Windows, wimlib now supports capturing and extracting long paths
536 (longer than the so-called MAX_PATH).
538 On Windows, `wimlib-imagex update' now acquires proper privileges when
539 running as an Administrator.
541 `wimlib-imagex update' will now complain if no image is specified when
542 trying to update a multi-image WIM.
544 `wimlib-imagex update' now supports specifying a single update command
545 directly on the command line using the --command option.
547 wimlib-imagex will now choose different units for progress messages,
548 depending on the amount of data that needs to be processed.
550 `wimlib-imagex append' will now generate a unique WIM image name if no
551 name is specified and the defaulted name already exists in the WIM.
553 wimlib now allows you to create unnamed WIM images, which can then only
554 be referred to by index.
556 wimlib now allows you to explicitly declare you want write access to a
557 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
560 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
563 Progress callbacks have been added to wimlib's wimlib_update_image()
566 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
567 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
570 NTFS-3g capture now only warns about two conditions previously treated
573 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
576 wimlib now correctly detects and returns an error when reading a WIM
577 image with a cyclic directory structure. (Fun fact: such a WIM will
578 crash Microsoft's software.)
581 Added new "extract" and "update" subcommands to wimlib-imagex, along
582 with associated APIs in the library. These commands are intended mainly
583 for Windows use but can be used on UNIX as well.
585 Many documentation improvements.
587 Fixed a bug in the Windows build where relative symbolic links were not
588 captured in reparse-point fixup mode.
590 Fixed a bug in the Windows build where file handles were left open to
591 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
593 Fixed a bug in the Windows build of wimlib-imagex where globbing
594 split-WIM parts could cause the program to crash.
596 Fixed a bug where the creation time of WIM images would be shown instead
597 of the last modification time.
599 With the Windows build it is now possible to restore a WIM containing
600 symbolic links as a non-Administrator; however you will receive warnings
601 about not being able to extract the symbolic links.
604 Capturing a WIM image should now be significantly faster in most cases
605 due to improved use of the operating system's cache and avoiding reading
606 files twice whenever possible.
608 The Windows build should now work on Windows XP.
610 The Windows build now supports capturing and restoring hidden,
611 compressed, sparse, and encrypted files.
613 The Windows build now supports capturing and applying WIM images from
614 filesystems other than NTFS (with some reduced functionality).
616 The Windows build now extracts short names correctly.
618 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
619 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
620 capture' and `wimlib-imagex apply'.
622 The performance of splitting and joining WIMs should be slightly
625 The LZX and XPRESS compression and decompression functions are now
626 exported from the library.
629 Improvements and bugfixes for the Windows build.
631 Added --strict-acls options.
633 Fixed the way that wimlib determines the order of images in the WIM.
636 Since wimlib can now be used on Windows, wimlib's implementation of
637 ImageX has been renamed to wimlib-imagex to avoid confusion with
638 Microsoft's implementation of ImageX, which would have the same file
639 name ("imagex.exe"). If you really don't like this you can pass the
640 --with-imagex-progname option to `configure' to choose a different name,
641 or even simply rename the binary yourself (but the former way will
642 configure the man pages to use the chosen name).
644 Various bugs fixed in the Windows build. Mainly to do with capturing
645 and restoring alternate data streams correctly in weird cases, and
646 requesting the correct privileges when opening files. Also added the
647 --noacls options to wimlib-imagex capture, append, and apply.
649 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
650 dynamically loaded, so this may make the library compatible with Windows
651 XP (however, there may still be other problems).
654 Added experimental support for native Windows builds. Binaries can be
655 downloaded from the SourceForge page.
657 --source-list option added to `imagex capture' and `imagex append'.
659 Better support for different character encodings.
662 Storing UNIX file owners, groups, and modes in WIM images is now
663 possible using `imagex capture' with the --unix-data flag.
665 Minor bug fixes and documentation fixes.
668 NTFS capture: Fixed capturing duplicate reparse points.
670 NTFS capture: Capture first unnamed stream if there are more than one
671 (print warning instead of error).
673 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
676 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
679 Update to work with ntfs-3g version 2013.1.13.
682 Fixed truncating file to shorter but non-zero length on read-write
685 Various code cleanups and minor documentation fixes.
688 LZX and XPRESS decompression have received some additional optimizations
689 and should now be even faster. (Although, they were already pretty
690 fast--- much faster than typical I/O speeds.)
692 Fixed a bug introduced in v1.2.1 that would cause a directory tree
693 containing hard links to be captured incorrectly in some cases.
696 By default, unmounting a read-write mounted WIM with 'imagex unmount
697 --commit' will now change the WIM in-place without needing to write the
698 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
701 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
702 for a response from the daemon servicing the mounted WIM. Instead,
703 every second 'imagex unmount' will check if the daemon is still alive,
704 and keep waiting if so, otherwise terminate with an error.
706 'imagex unmount --commit' on a read-write mounted WIM will now print
707 progress information regarding the writing of new or modified streams
708 the WIM, just like when capturing or appending a WIM.
710 A small change has been made to XPRESS compression and it should improve
711 the compression ratio slightly.
713 A change was made that may improve performance slightly when applying a
714 WIM image to a NTFS volume.
716 Microsoft has managed to introduce even more bugs into their software,
717 and now the WIMs for Windows 8 have incorrect (too low) reference counts
718 for some streams. This is unsafe because such streams can be removed
719 when they are in actuality still referenced in the WIM (perhaps by a
720 different image). wimlib will now work around this problem by fixing
721 the stream reference counts. This is only done when wimlib_delete_image() is
722 called ('imagex delete') or when wimlib_mount_image() is called with
723 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
724 requires reading the metadata for all images in the WIM, so this will
725 make these operations noticably slower on WIMs with multiple images.
727 Various other bugfixes.
730 Appending images to a WIM is now be done by default without re-building
731 the whole WIM. Use the --rebuild flag to get the old behavior (which
732 was to re-build the entire WIM when a new image is appended).
734 A new command `imagex optimize' is now available to manually re-build a
735 WIM that has wasted space due to repeated appends.
737 Progress information has been improved, and now arbitrary callback
738 functions can be used to show the progress of a WIM operation.
740 A possible bug with changing the bootable image of a WIM was fixed.
742 Some advisory locking is now done to prevent two processes from
743 modifying a WIM at the same time (but only in some cases). For example,
744 you cannot mount two images from a WIM read-write at the same time.
746 Some functions have been reorganized:
747 * wimlib_mount() renamed to wimlib_mount_image().
748 * wimlib_unmount() renamed to wimlib_unmount_image().
749 * wimlib_overwrite_xml_and_header() removed as
750 wimlib_overwrite() suffices now.
751 * wimlib_apply_image_to_ntfs_volume() removed as
752 wimlib_extract_image() suffices now.
753 * wimlib_add_image_from_ntfs_volume() removed as
754 * wimlib_add_image() suffices now.
756 Previously, the soname of libwim.so has been 0.0.0, despite many
757 interface changes. The soname is now updated to 1.0.0 and will now be
758 updated each release.
761 Resources will now be compressed using multiple threads by default.
762 (This applies to `imagex capture', `imagex append', and `imagex
765 Some performance improvements in mounted WIMs.
767 More progress information is shown when capturing a WIM.
770 Lots of minor fixes, code cleanups, and some documentation updates.
771 Nothing in particular is really noteworthy.
774 LZX and XPRESS compression improvements.
776 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
777 Link Bytes of the WIM.
780 Fixed bug when capturing NTFS file with multiple named data streams.
782 Internally, we are now using inode structures, even though these don't
783 appear literally in the WIM file. This simplifies some of the code
784 (mainly for WIM mounting) and likely fixed a few problems, although it
788 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
792 Enough changes to call it version 1.0.0!
794 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
795 to a NTFS volume, is now supported.
797 Hard links and symbolic links have much improved support. They are
798 supported for WIM capture, WIM application, and mounted WIMs (you can
799 even make them on read-write mounted WIMs).
801 Alternate data streams are now supported on mounted WIMs through an
802 xattr or a Windows-style stream interface. Also they are supported when
803 capturing a WIM from NTFS or applying a WIM to NTFS.
805 Split WIMs are better supported. You may now apply an image directly
806 from a split WIM, mount an image from a split WIM read-only, or export
807 an image from a split WIM.
809 Using a capture configuration file is now supported (but not fully yet).
811 SHA1 message digests are checked in more places, so we can make sure
812 applied and captured data is correct.
814 Man pages have been updated and consolidated.
817 Fixed segfault when unmounting read-only WIM.
820 Support for joining and splitting WIMs.
821 Also, security data is now preserved by default.
824 Can now build with older gcc and system headers, like on CentOS 5.
827 Fixed bug that made it impossible to overwrite files in read-write
831 Write byte-order mark before WIM XML data. (imagex.exe requires this to
