2 Fixed a bug in the LZX decompressor: malicious input data could cause
3 out of bounds writes to memory (since wimlib v1.2.2).
5 The output of the 'wiminfo' command now consolidates various boolean
6 flags (such as "Relative path junction") into a single line.
8 A file can now have both an unnamed data stream ("file contents") and a
9 reparse point stream. Such files can exist as a result of the use of
10 certain Windows features, such as offline storage, including "OneDrive".
11 wimlib will now store and restore both streams on Windows as well as in
12 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
14 On Windows, named data streams of encrypted files are no longer stored
15 twice in WIM archives.
17 On Windows, named data streams are now correctly extracted to existing
18 "readonly" directories. Before, an error would be reported.
20 On Windows, it is now possible to do a "WIMBoot mode" extraction with
21 non-standalone WIMs such as delta WIMs.
23 On Windows, when doing an extraction in "WIMBoot mode", files larger
24 than 4 gigabytes are now never extracted as externally backed. This
25 works around a bug in Microsoft's "WOF" driver.
27 The '--enable-verify-compression' configure option has been removed. If
28 you want to verify a WIM file, use the 'wimverify' program.
30 The way the "file count", "directory count", "total bytes", and "hard
31 link bytes" image statistics (stored in the WIM XML data) is calculated
32 has been slightly changed.
34 In mounted WIM images, the disk usage provided for each file (st_blocks)
35 is now the compressed size rather than the uncompressed size.
37 The performance of the NTFS-3g and Windows capture modes has been
40 On UNIX-like systems, symbolic links whose targets contain the backslash
41 character are now handled correctly (losslessly).
44 Improved the LZX compressor. It is now 15-20% faster than before and
45 provides a slightly better compression ratio.
47 Improved the LZMS compressor. It now provides a compression ratio
48 slightly better than WIMGAPI while still being faster and using slightly
51 The compression chunk size in solid resources, e.g. when capturing or
52 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
53 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
54 better compression ratio and is the same value that WIMGAPI uses. The
55 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
56 lower than WIMGAPI's memory usage, but if it is too much, it is still
57 possible to choose a lower value, e.g. with the '--solid-chunk-size'
58 option to wimlib-imagex.
60 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
61 accept the 'K', 'M', and 'G' suffixes.
63 Files are now sorted by name extension when creating a solid WIM file.
65 Fixed various issues related to capture/apply of EFS-encrypted files on
68 The file list printed by 'wimdir' is now sorted by the platform-specific
69 case sensitivity setting, rather than always case sensitively. This
70 also affects the library function wimlib_iterate_dir_tree().
72 On Windows, some error and warning messages have been improved.
75 The Windows binary distribution no longer contains third party DLLs.
76 These dependencies are instead compiled directly into the libwim DLL.
78 Added more fixes for wimlib on non-x86 architectures such as ARM.
80 Extracting files to a Windows PE in-memory filesystem no longer fails if
81 the target files do not yet exist.
83 Improved the performance of XPRESS compression and LZMS decompression.
85 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
86 It will automatically be faster on newer Intel and AMD processors.
88 Removed the --with-imagex-progname and --enable-more-assertions
92 Fix for very slow export from solid WIM / ESD files.
94 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
96 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
97 may use this to treat some types of errors as non-fatal.
99 The library now permits making in-memory changes to a WIMStruct backed
100 by a read-only WIM file.
102 Fixes for "WIMBoot" extraction mode (Windows only):
104 When not using the WOF driver, extraction no longer fails if the
105 disk containing the WIM file has too many partitions.
107 When matching patterns in [PrepopulateList], all hard links of
108 each file are now considered.
110 The system registry files are now automatically treated as being
111 in [PrepopulateList].
113 Added a hack to try to work around an intermittent bug in
114 Microsoft's WOF (Windows Overlay Filesystem) driver.
117 Made more improvements to the XPRESS, LZX, and LZMS compressors.
119 A number of improvements to the Windows port:
121 Fixes for setting short filenames.
123 Faster "WIMBoot" extraction.
125 Updated and slimmed down the dependent DLLs.
127 ACL inheritence bits are now restored.
129 Mandatory integrity labels are now backed up and restored.
131 Added a workaround for an issue where in rare cases, wimlib could create
132 a compressed data stream that could not be read correctly by Windows
133 after an extraction in "WIMBoot" mode.
136 Added file count progress data for
137 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
138 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
140 Added support for testing file exclusions via the user-provided
143 Some documentation improvements.
145 Made some clarifications to the license text in the COPYING file.
148 Made more improvements to the XPRESS, LZX, and LZMS compressors.
150 The default compression mode for wimcapture is now LZX compression in
151 its default mode, which is the same as '--compress=maximum'.
153 You can now specify an optional integer compression level to the
154 '--compress' option; e.g. '--compress=lzx:75'.
156 Made a minor change to the LZMS compressor and decompressor to fix an
157 incompatibility with the Microsoft implementation. In the unlikely
158 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
159 earlier and a checksum error is reported when extracting files from it
160 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
163 Added 'verify' subcommand to wimlib-imagex.
165 Notable library changes:
167 Custom compressor parameters have been removed from the library
168 in favor of the simpler level-based API.
170 Decompressor parameters have been removed entirely.
172 Library users can now specify a custom file for warning and
173 error messages to be sent to, rather than the default of
176 New progress messages:
177 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
178 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
180 New function: wimlib_verify_wim().
183 Improved compression, decompression, and extraction performance.
185 Improved compatibility with version 3584 WIM / ESD files:
186 - Add support for reading and writing multiple solid blocks per
187 archive, which WIMGAPI/DISM can create when appending an image.
188 - Correctly create solid blocks larger than 4 GiB.
190 'add' commands passed to wimupdate will now replace existing
191 nondirectory files by default. Use the --no-replace option to get the
194 The license for the library now contains an exception that allows using
195 it under the LGPL. See the COPYING file for details.
197 In reparse-point fixup mode (the default for capture), symbolic links
198 and junctions that point outside the tree being captured are no longer
199 excluded from capture.
201 Added support for "WIMBoot" capture and extraction. See the
202 documentation for the new '--wimboot' option to wimcapture and wimapply
203 for more information.
205 On UNIX-like systems, you can now backup and restore device nodes, named
206 pipes, and sockets. In addition, 32-bit user and group IDs are now
209 The way that UNIX data is stored in WIM files has been changed. If you
210 captured any WIMs with the --unix-data option, to upgrade them you'll
211 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
212 re-capture them with --unix-data using this version.
214 wimlib now understands tagged metadata items, such as object IDs, that
215 can be stored in WIM directory entries.
217 Removed the --hardlink and --symlink options to wimapply, since I don't
218 think they are too useful and they got in the way of improving the code.
220 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
222 The 'mkwinpeimg' script now supports writing the ISO image to standard
225 The <ARCH> element in WIM XML data is now exported correctly.
227 On Windows, sparse file attributes are no longer set on extracted files.
228 Oddly enough, this actually saves disk space in some cases.
230 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
231 supported. Mounting WIM images now always requires extended attribute
232 support. Use --without-fuse to disable support for mounting WIM images;
233 this will also disable the need for extended attribute support.
235 Configuring with --enable-ssse3-sha1 now works correctly.
237 The shared library version has been bumped up. The main
238 incompatibilities are:
240 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
241 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
244 - User-provided progress functions are now registered using a
245 separate function, wimlib_register_progress_function(). The
246 'progress_func' argument to many functions no longer exists.
248 - The return value from user-provided progress functions is now
251 - A context argument has been added to the prototype of
252 user-provided progress functions.
254 - 'struct wimlib_capture_config' has been removed. The library
255 now takes the path to the configuration file directly. This
256 affects wimlib_add_image(), wimlib_add_image_multisource(),
257 and wimlib_update_image(). However, a NULL value passed in
258 the argument retains the same meaning.
260 - Removed deprecated functions: some (de)compression functions,
261 wimlib_extract_files(), and wimlib_print_metadata().
263 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
264 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
265 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
267 - Removed some progress messages:
268 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
269 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
270 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
273 - Removed some error codes. Numbering stays the same.
275 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
276 WIMLIB_UNMOUNT_FLAG_FORCE.
278 - WIM paths passed to progress functions now have a leading
282 Case-insensitive comparisons of strings (e.g. filenames) containing
283 UTF-16 codepoints above 32767 are now done correctly.
285 Fixed build failure on Mac OS X.
287 wimunmount now provides the '--new-image' option to cause changes to a
288 read-write mounted image to be committed as a new image rather than as
289 an update of the mounted image. (The corresponding new library flag is
290 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
292 The LZMS ("recovery") compression chunk size, or "dictionary size", may
293 now be up to 1 GiB (1,073,741,824 bytes).
295 The performance of LZX ("maximum") and LZMS ("recovery") compression
296 with large chunk sizes has been slightly improved.
299 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
300 decompressed correctly.
302 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
303 occurred in an unlikely case, and due to validity checks it did not
304 affect successfully created archives.
306 Fixed a minor compatibility issue with the LZMS compressor and
307 decompressor. This is *not* the default compression type and was only
308 introduced in v1.6.0. In the unlikely event that you created an
309 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
310 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
313 Memory usage for LZMS and LZX compression has been decreased.
315 wimextract now allows wildcard characters in paths specified on the
316 command line. Also, the '--strict-wildcards' option has been removed
317 and replaced with the inverse option '--nullglob'. See the
318 documentation for wimextract for more details and changes.
320 The wimlib_extract_files() function is now considered deprecated in
321 favor of wimlib_extract_paths().
323 Fixed more permissions problems when extracting files on Windows.
325 A new '--no-attributes' option has been added to wimapply and
326 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
328 The default chunk size is now set correctly when changing the
329 compression type of a WIM, for example with 'wimoptimize'.
331 The '--metadata' option to wiminfo has been replaced with the
332 '--detailed' option to wimdir.
334 In relevant wimlib-imagex commands, '--solid' may now be used as an
335 alias for '--pack-streams'.
338 Support for extracting and updating the new version 3584 WIMs has been
339 added. These WIMs typically pack many streams ("files") together into a
340 single compressed resource, thereby saving space. This degrades the
341 performance of random access (such as that which occurs on a mounted
342 image), but optimizations have been implemented for extraction. These
343 new WIM files also typically use a new compression format (LZMS), which
344 is similar to LZMA and can offer a better compression ratio than LZX.
345 These new WIM files can be created using `wimcapture' with
346 the '--compress=lzms --pack-streams' options. Note: this new WIM format
347 is used by the Windows 8 web downloader, but important segments of the
348 raw '.esd' files are encrypted, so wimlib will not be able to extract
349 such files until they are first decrypted.
351 wimlib now supports extracting files and directories from a WIM image
352 based on a "listfile" that itself contains the list of paths to extract.
353 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
354 and for the library itself, the new APIs are wimlib_extract_pathlist()
355 and wimlib_extract_paths(). Path globs containing wildcard characters
358 For searching WIM files, wimlib now has configurable case sensitivity.
359 The default on Windows is still case-insensitive and the default on
360 UNIX-like systems is still case-sensitive, but this can be overridden
361 on either platform through flags to wimlib_global_init(). For
362 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
363 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
366 Support for compression chunk sizes greater than the default of 32768
367 bytes has been added. A larger chunk size typically results in a better
368 compression ratio. However, the MS implementation is seemingly not
369 compatible with all chunk sizes, especially for LZX compression, so the
370 defaults remain unchanged, with the exception of the new LZMS-compressed
371 WIMs, which use a larger chunk size by default.
373 The compression/decompression API exported by wimlib has been changed.
374 Now one set of functions handles all supported compression formats.
376 `wimcapture' and `wimappend' will now display the progress of scanning
377 the directory tree to capture, in addition to the progress of writing
378 data to the WIM. The '--verbose' option no longer does anything. The
379 library API change for this is the addition of several members to
380 `struct wimlib_progress_info_scan' available to progress callbacks.
382 `mkwinpeimg' now correctly handles the '--start-script' option when the
383 start script is not in the working directory.
385 Sequential extraction, previously requested by using
386 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
387 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
388 behavior (extract in file order).
391 The new LZX compressor added in v1.5.2 has been improved and is now
392 enabled by default, except when `wimcapture' or `wimappend' is run
393 *without* the '--compress' option, in which case the faster LZX
394 compressor is used (the same as before). This behavior is reasonably
395 consistent with ImageX which actually uses "fast" (XPRESS) compression
396 by default. In those cases, use '--compress=maximum' to explicitly
397 capture a WIM image using the new (slower but better) LZX compressor.
399 The '--compress-slow' option still exists to `wimlib-imagex optimize',
400 but its new behavior is to tweak the new LZX compressor even more to
401 produce an even better compression ratio at the cost of more time spent
404 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
405 which recompresses the WIM file using the specified compression TYPE.
406 The new library API function used for this is
407 wimlib_set_output_compression_type().
409 Added the wimlib_get_xml_data() function to allow library clients to
410 easily retrieve the raw XML data from a WIM file if needed.
412 Fixed a bug that could cause an error code to be incorrectly returned
413 when writing XML data containing a <WINDOWS> element.
415 Mounted WIM images will now correctly show the default file stream even
416 if appears in the alternate data stream entries of the corresponding WIM
420 Added a new experimental LZX compressor which can be enabled by passing
421 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
422 optimize'. (The latter is only applicable if the WIM is already
423 LZX-compressed and the '--recompress' option is also given.) The
424 experimental compressor is much slower but compresses the data slightly
425 more --- currently usually to within a fraction of a percent of the
426 results from WIMGAPI/ImageX.
428 A workaround has been added for compatibility with versions of WinPE
429 that interpret alternate data stream entries in the boot WIM
432 An alignment bug that caused a crash in the LZX decompressor on some
435 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
436 the WIM header when restoring the previous state of a WIM it failed to
439 Added a workaround to avoid an access denied error on Windows when
440 replacing a WIM file that another process has opened.
443 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
444 needed to be handled.
446 A bug in the interpretation of negative IMAGE indices in the
447 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
448 `wimlib-imagex append' has been fixed.
450 A workaround has been added to successfully apply security descriptors
451 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
452 2013.1.13 or earlier.
454 `wimlib-imagex capture' can now accept the '--delta-from' option
458 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
459 to standard output and applying images from standard input, but they are
460 not compatible with Microsoft's software and are not created by default.
461 See the documentation for --pipable flag of `wimlib-imagex capture' for
464 To better support incremental backups, added support for declaring an
465 image as a modified form of another image. See the documentation for
466 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
469 Added supported for "delta" WIMs. See the documentation for the
470 '--delta-from' option of `wimlib-imagex capture'.
472 The library support for managing split WIMs has been changed to support
473 other arrangements, such as delta WIMs, and be easier to use. This
474 change is visible in `wimlib-imagex', which also can now accept the
475 '--ref' option multiple times, and also now supports "delta" WIMs as
478 wimlib now preserves WIM integrity tables by default, even if
479 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
480 behavior of `wimlib-imagex' whenever the WIM being operated on contains
481 an integrity table and the '--check' option is not specified.
483 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
484 (when --compress is not specified). This provides the best compression
485 ratio by default, which is usually what is desired, at a cost of some
488 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
489 is the command as in `wimlib-imagex COMMAND'; for example, it can be
490 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
491 appropriate hard links are created in UNIX installations of
492 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
493 batch files that emulate this behavior are generated.
495 Security descriptors are now extracted correctly on Windows.
497 Fixed archiving DOS names in NTFS-3g capture mode.
499 The extraction code has been rewritten and it will now be easier to
500 support new features on all supported backends (currently Win32, UNIX,
501 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
502 now supported on all backends, not just UNIX.
504 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
505 than the WAIK itself.
507 wimlib_global_init() now, by default, attempts to acquire additional
508 privileges on Windows, so library clients need not do this.
510 This update bumps the shared library version number up to 9, since it is
511 not binary compatibible with previous releases.
514 Fixed bug in `wimlib-imagex export' that made it impossible to export an
515 image from a WIM that is readonly at the filesystem level.
517 Return error code rather than segfaulting when trying to list files from
518 a non-first part of a split WIM.
520 Joining a WIM will now preserve the RP_FIX and READONLY flags.
523 On Windows, paths given to wimlib-imagex are now treated case
526 Improved behavior regarding invalid filenames; in particular, on
527 Windows, wimlib-imagex will, when extracting, now omit (with an option
528 to override this default) filenames differing only in case, or filenames
529 containing characters not valid on Windows.
531 On Windows, wimlib now supports capturing and extracting long paths
532 (longer than the so-called MAX_PATH).
534 On Windows, `wimlib-imagex update' now acquires proper privileges when
535 running as an Administrator.
537 `wimlib-imagex update' will now complain if no image is specified when
538 trying to update a multi-image WIM.
540 `wimlib-imagex update' now supports specifying a single update command
541 directly on the command line using the --command option.
543 wimlib-imagex will now choose different units for progress messages,
544 depending on the amount of data that needs to be processed.
546 `wimlib-imagex append' will now generate a unique WIM image name if no
547 name is specified and the defaulted name already exists in the WIM.
549 wimlib now allows you to create unnamed WIM images, which can then only
550 be referred to by index.
552 wimlib now allows you to explicitly declare you want write access to a
553 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
556 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
559 Progress callbacks have been added to wimlib's wimlib_update_image()
562 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
563 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
566 NTFS-3g capture now only warns about two conditions previously treated
569 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
572 wimlib now correctly detects and returns an error when reading a WIM
573 image with a cyclic directory structure. (Fun fact: such a WIM will
574 crash Microsoft's software.)
577 Added new "extract" and "update" subcommands to wimlib-imagex, along
578 with associated APIs in the library. These commands are intended mainly
579 for Windows use but can be used on UNIX as well.
581 Many documentation improvements.
583 Fixed a bug in the Windows build where relative symbolic links were not
584 captured in reparse-point fixup mode.
586 Fixed a bug in the Windows build where file handles were left open to
587 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
589 Fixed a bug in the Windows build of wimlib-imagex where globbing
590 split-WIM parts could cause the program to crash.
592 Fixed a bug where the creation time of WIM images would be shown instead
593 of the last modification time.
595 With the Windows build it is now possible to restore a WIM containing
596 symbolic links as a non-Administrator; however you will receive warnings
597 about not being able to extract the symbolic links.
600 Capturing a WIM image should now be significantly faster in most cases
601 due to improved use of the operating system's cache and avoiding reading
602 files twice whenever possible.
604 The Windows build should now work on Windows XP.
606 The Windows build now supports capturing and restoring hidden,
607 compressed, sparse, and encrypted files.
609 The Windows build now supports capturing and applying WIM images from
610 filesystems other than NTFS (with some reduced functionality).
612 The Windows build now extracts short names correctly.
614 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
615 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
616 capture' and `wimlib-imagex apply'.
618 The performance of splitting and joining WIMs should be slightly
621 The LZX and XPRESS compression and decompression functions are now
622 exported from the library.
625 Improvements and bugfixes for the Windows build.
627 Added --strict-acls options.
629 Fixed the way that wimlib determines the order of images in the WIM.
632 Since wimlib can now be used on Windows, wimlib's implementation of
633 ImageX has been renamed to wimlib-imagex to avoid confusion with
634 Microsoft's implementation of ImageX, which would have the same file
635 name ("imagex.exe"). If you really don't like this you can pass the
636 --with-imagex-progname option to `configure' to choose a different name,
637 or even simply rename the binary yourself (but the former way will
638 configure the man pages to use the chosen name).
640 Various bugs fixed in the Windows build. Mainly to do with capturing
641 and restoring alternate data streams correctly in weird cases, and
642 requesting the correct privileges when opening files. Also added the
643 --noacls options to wimlib-imagex capture, append, and apply.
645 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
646 dynamically loaded, so this may make the library compatible with Windows
647 XP (however, there may still be other problems).
650 Added experimental support for native Windows builds. Binaries can be
651 downloaded from the SourceForge page.
653 --source-list option added to `imagex capture' and `imagex append'.
655 Better support for different character encodings.
658 Storing UNIX file owners, groups, and modes in WIM images is now
659 possible using `imagex capture' with the --unix-data flag.
661 Minor bug fixes and documentation fixes.
664 NTFS capture: Fixed capturing duplicate reparse points.
666 NTFS capture: Capture first unnamed stream if there are more than one
667 (print warning instead of error).
669 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
672 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
675 Update to work with ntfs-3g version 2013.1.13.
678 Fixed truncating file to shorter but non-zero length on read-write
681 Various code cleanups and minor documentation fixes.
684 LZX and XPRESS decompression have received some additional optimizations
685 and should now be even faster. (Although, they were already pretty
686 fast--- much faster than typical I/O speeds.)
688 Fixed a bug introduced in v1.2.1 that would cause a directory tree
689 containing hard links to be captured incorrectly in some cases.
692 By default, unmounting a read-write mounted WIM with 'imagex unmount
693 --commit' will now change the WIM in-place without needing to write the
694 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
697 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
698 for a response from the daemon servicing the mounted WIM. Instead,
699 every second 'imagex unmount' will check if the daemon is still alive,
700 and keep waiting if so, otherwise terminate with an error.
702 'imagex unmount --commit' on a read-write mounted WIM will now print
703 progress information regarding the writing of new or modified streams
704 the WIM, just like when capturing or appending a WIM.
706 A small change has been made to XPRESS compression and it should improve
707 the compression ratio slightly.
709 A change was made that may improve performance slightly when applying a
710 WIM image to a NTFS volume.
712 Microsoft has managed to introduce even more bugs into their software,
713 and now the WIMs for Windows 8 have incorrect (too low) reference counts
714 for some streams. This is unsafe because such streams can be removed
715 when they are in actuality still referenced in the WIM (perhaps by a
716 different image). wimlib will now work around this problem by fixing
717 the stream reference counts. This is only done when wimlib_delete_image() is
718 called ('imagex delete') or when wimlib_mount_image() is called with
719 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
720 requires reading the metadata for all images in the WIM, so this will
721 make these operations noticably slower on WIMs with multiple images.
723 Various other bugfixes.
726 Appending images to a WIM is now be done by default without re-building
727 the whole WIM. Use the --rebuild flag to get the old behavior (which
728 was to re-build the entire WIM when a new image is appended).
730 A new command `imagex optimize' is now available to manually re-build a
731 WIM that has wasted space due to repeated appends.
733 Progress information has been improved, and now arbitrary callback
734 functions can be used to show the progress of a WIM operation.
736 A possible bug with changing the bootable image of a WIM was fixed.
738 Some advisory locking is now done to prevent two processes from
739 modifying a WIM at the same time (but only in some cases). For example,
740 you cannot mount two images from a WIM read-write at the same time.
742 Some functions have been reorganized:
743 * wimlib_mount() renamed to wimlib_mount_image().
744 * wimlib_unmount() renamed to wimlib_unmount_image().
745 * wimlib_overwrite_xml_and_header() removed as
746 wimlib_overwrite() suffices now.
747 * wimlib_apply_image_to_ntfs_volume() removed as
748 wimlib_extract_image() suffices now.
749 * wimlib_add_image_from_ntfs_volume() removed as
750 * wimlib_add_image() suffices now.
752 Previously, the soname of libwim.so has been 0.0.0, despite many
753 interface changes. The soname is now updated to 1.0.0 and will now be
754 updated each release.
757 Resources will now be compressed using multiple threads by default.
758 (This applies to `imagex capture', `imagex append', and `imagex
761 Some performance improvements in mounted WIMs.
763 More progress information is shown when capturing a WIM.
766 Lots of minor fixes, code cleanups, and some documentation updates.
767 Nothing in particular is really noteworthy.
770 LZX and XPRESS compression improvements.
772 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
773 Link Bytes of the WIM.
776 Fixed bug when capturing NTFS file with multiple named data streams.
778 Internally, we are now using inode structures, even though these don't
779 appear literally in the WIM file. This simplifies some of the code
780 (mainly for WIM mounting) and likely fixed a few problems, although it
784 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
788 Enough changes to call it version 1.0.0!
790 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
791 to a NTFS volume, is now supported.
793 Hard links and symbolic links have much improved support. They are
794 supported for WIM capture, WIM application, and mounted WIMs (you can
795 even make them on read-write mounted WIMs).
797 Alternate data streams are now supported on mounted WIMs through an
798 xattr or a Windows-style stream interface. Also they are supported when
799 capturing a WIM from NTFS or applying a WIM to NTFS.
801 Split WIMs are better supported. You may now apply an image directly
802 from a split WIM, mount an image from a split WIM read-only, or export
803 an image from a split WIM.
805 Using a capture configuration file is now supported (but not fully yet).
807 SHA1 message digests are checked in more places, so we can make sure
808 applied and captured data is correct.
810 Man pages have been updated and consolidated.
813 Fixed segfault when unmounting read-only WIM.
816 Support for joining and splitting WIMs.
817 Also, security data is now preserved by default.
820 Can now build with older gcc and system headers, like on CentOS 5.
823 Fixed bug that made it impossible to overwrite files in read-write
827 Write byte-order mark before WIM XML data. (imagex.exe requires this to
