2 Made yet another round of performance improvements to the XPRESS, LZX,
5 On Windows, wimextract and its underlying library function
6 wimlib_extract_paths() will no longer fail if given a target directory
7 path ending in a slash.
10 Made more improvements to the XPRESS, LZX, and LZMS compressors.
12 The default compression mode for wimcapture is now LZX compression in
13 its default mode, which is the same as '--compress=maximum'.
15 You can now specify an optional integer compression level to the
16 '--compress' option; e.g. '--compress=lzx:75'.
18 Made a minor change to the LZMS compressor and decompressor to fix an
19 incompatibility with the Microsoft implementation. In the unlikely
20 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
21 earlier and a checksum error is reported when extracting files from it
22 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
25 Added 'verify' subcommand to wimlib-imagex.
27 Notable library changes:
29 Custom compressor parameters have been removed from the library
30 in favor of the simpler level-based API.
32 Decompressor parameters have been removed entirely.
34 Library users can now specify a custom file for warning and
35 error messages to be sent to, rather than the default of
38 New progress messages:
39 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
40 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
42 New function: wimlib_verify_wim().
45 Improved compression, decompression, and extraction performance.
47 Improved compatibility with version 3584 WIM / ESD files:
48 - Add support for reading and writing multiple solid blocks per
49 archive, which WIMGAPI/DISM can create when appending an image.
50 - Correctly create solid blocks larger than 4 GiB.
52 'add' commands passed to wimupdate will now replace existing
53 nondirectory files by default. Use the --no-replace option to get the
56 The license for the library now contains an exception that allows using
57 it under the LGPL. See the COPYING file for details.
59 In reparse-point fixup mode (the default for capture), symbolic links
60 and junctions that point outside the tree being captured are no longer
61 excluded from capture.
63 Added support for "WIMBoot" capture and extraction. See the
64 documentation for the new '--wimboot' option to wimcapture and wimapply
67 On UNIX-like systems, you can now backup and restore device nodes, named
68 pipes, and sockets. In addition, 32-bit user and group IDs are now
71 The way that UNIX data is stored in WIM files has been changed. If you
72 captured any WIMs with the --unix-data option, to upgrade them you'll
73 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
74 re-capture them with --unix-data using this version.
76 wimlib now understands tagged metadata items, such as object IDs, that
77 can be stored in WIM directory entries.
79 Removed the --hardlink and --symlink options to wimapply, since I don't
80 think they are too useful and they got in the way of improving the code.
82 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
84 The 'mkwinpeimg' script now supports writing the ISO image to standard
87 The <ARCH> element in WIM XML data is now exported correctly.
89 On Windows, sparse file attributes are no longer set on extracted files.
90 Oddly enough, this actually saves disk space in some cases.
92 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
93 supported. Mounting WIM images now always requires extended attribute
94 support. Use --without-fuse to disable support for mounting WIM images;
95 this will also disable the need for extended attribute support.
97 Configuring with --enable-ssse3-sha1 now works correctly.
99 The shared library version has been bumped up. The main
100 incompatibilities are:
102 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
103 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
106 - User-provided progress functions are now registered using a
107 separate function, wimlib_register_progress_function(). The
108 'progress_func' argument to many functions no longer exists.
110 - The return value from user-provided progress functions is now
113 - A context argument has been added to the prototype of
114 user-provided progress functions.
116 - 'struct wimlib_capture_config' has been removed. The library
117 now takes the path to the configuration file directly. This
118 affects wimlib_add_image(), wimlib_add_image_multisource(),
119 and wimlib_update_image(). However, a NULL value passed in
120 the argument retains the same meaning.
122 - Removed deprecated functions: some (de)compression functions,
123 wimlib_extract_files(), and wimlib_print_metadata().
125 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
126 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
127 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
129 - Removed some progress messages:
130 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
131 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
132 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
135 - Removed some error codes. Numbering stays the same.
137 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
138 WIMLIB_UNMOUNT_FLAG_FORCE.
140 - WIM paths passed to progress functions now have a leading
144 Case-insensitive comparisons of strings (e.g. filenames) containing
145 UTF-16 codepoints above 32767 are now done correctly.
147 Fixed build failure on Mac OS X.
149 wimunmount now provides the '--new-image' option to cause changes to a
150 read-write mounted image to be committed as a new image rather than as
151 an update of the mounted image. (The corresponding new library flag is
152 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
154 The LZMS ("recovery") compression chunk size, or "dictionary size", may
155 now be up to 1 GiB (1,073,741,824 bytes).
157 The performance of LZX ("maximum") and LZMS ("recovery") compression
158 with large chunk sizes has been slightly improved.
161 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
162 decompressed correctly.
164 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
165 occurred in an unlikely case, and due to validity checks it did not
166 affect successfully created archives.
168 Fixed a minor compatibility issue with the LZMS compressor and
169 decompressor. This is *not* the default compression type and was only
170 introduced in v1.6.0. In the unlikely event that you created an
171 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
172 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
175 Memory usage for LZMS and LZX compression has been decreased.
177 wimextract now allows wildcard characters in paths specified on the
178 command line. Also, the '--strict-wildcards' option has been removed
179 and replaced with the inverse option '--nullglob'. See the
180 documentation for wimextract for more details and changes.
182 The wimlib_extract_files() function is now considered deprecated in
183 favor of wimlib_extract_paths().
185 Fixed more permissions problems when extracting files on Windows.
187 A new '--no-attributes' option has been added to wimapply and
188 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
190 The default chunk size is now set correctly when changing the
191 compression type of a WIM, for example with 'wimoptimize'.
193 The '--metadata' option to wiminfo has been replaced with the
194 '--detailed' option to wimdir.
196 In relevant wimlib-imagex commands, '--solid' may now be used as an
197 alias for '--pack-streams'.
200 Support for extracting and updating the new version 3584 WIMs has been
201 added. These WIMs typically pack many streams ("files") together into a
202 single compressed resource, thereby saving space. This degrades the
203 performance of random access (such as that which occurs on a mounted
204 image), but optimizations have been implemented for extraction. These
205 new WIM files also typically use a new compression format (LZMS), which
206 is similar to LZMA and can offer a better compression ratio than LZX.
207 These new WIM files can be created using `wimcapture' with
208 the '--compress=lzms --pack-streams' options. Note: this new WIM format
209 is used by the Windows 8 web downloader, but important segments of the
210 raw '.esd' files are encrypted, so wimlib will not be able to extract
211 such files until they are first decrypted.
213 wimlib now supports extracting files and directories from a WIM image
214 based on a "listfile" that itself contains the list of paths to extract.
215 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
216 and for the library itself, the new APIs are wimlib_extract_pathlist()
217 and wimlib_extract_paths(). Path globs containing wildcard characters
220 For searching WIM files, wimlib now has configurable case sensitivity.
221 The default on Windows is still case-insensitive and the default on
222 UNIX-like systems is still case-sensitive, but this can be overridden
223 on either platform through flags to wimlib_global_init(). For
224 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
225 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
228 Support for compression chunk sizes greater than the default of 32768
229 bytes has been added. A larger chunk size typically results in a better
230 compression ratio. However, the MS implementation is seemingly not
231 compatible with all chunk sizes, especially for LZX compression, so the
232 defaults remain unchanged, with the exception of the new LZMS-compressed
233 WIMs, which use a larger chunk size by default.
235 The compression/decompression API exported by wimlib has been changed.
236 Now one set of functions handles all supported compression formats.
238 `wimcapture' and `wimappend' will now display the progress of scanning
239 the directory tree to capture, in addition to the progress of writing
240 data to the WIM. The '--verbose' option no longer does anything. The
241 library API change for this is the addition of several members to
242 `struct wimlib_progress_info_scan' available to progress callbacks.
244 `mkwinpeimg' now correctly handles the '--start-script' option when the
245 start script is not in the working directory.
247 Sequential extraction, previously requested by using
248 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
249 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
250 behavior (extract in file order).
253 The new LZX compressor added in v1.5.2 has been improved and is now
254 enabled by default, except when `wimcapture' or `wimappend' is run
255 *without* the '--compress' option, in which case the faster LZX
256 compressor is used (the same as before). This behavior is reasonably
257 consistent with ImageX which actually uses "fast" (XPRESS) compression
258 by default. In those cases, use '--compress=maximum' to explicitly
259 capture a WIM image using the new (slower but better) LZX compressor.
261 The '--compress-slow' option still exists to `wimlib-imagex optimize',
262 but its new behavior is to tweak the new LZX compressor even more to
263 produce an even better compression ratio at the cost of more time spent
266 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
267 which recompresses the WIM file using the specified compression TYPE.
268 The new library API function used for this is
269 wimlib_set_output_compression_type().
271 Added the wimlib_get_xml_data() function to allow library clients to
272 easily retrieve the raw XML data from a WIM file if needed.
274 Fixed a bug that could cause an error code to be incorrectly returned
275 when writing XML data containing a <WINDOWS> element.
277 Mounted WIM images will now correctly show the default file stream even
278 if appears in the alternate data stream entries of the corresponding WIM
282 Added a new experimental LZX compressor which can be enabled by passing
283 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
284 optimize'. (The latter is only applicable if the WIM is already
285 LZX-compressed and the '--recompress' option is also given.) The
286 experimental compressor is much slower but compresses the data slightly
287 more --- currently usually to within a fraction of a percent of the
288 results from WIMGAPI/ImageX.
290 A workaround has been added for compatibility with versions of WinPE
291 that interpret alternate data stream entries in the boot WIM
294 An alignment bug that caused a crash in the LZX decompressor on some
297 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
298 the WIM header when restoring the previous state of a WIM it failed to
301 Added a workaround to avoid an access denied error on Windows when
302 replacing a WIM file that another process has opened.
305 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
306 needed to be handled.
308 A bug in the interpretation of negative IMAGE indices in the
309 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
310 `wimlib-imagex append' has been fixed.
312 A workaround has been added to successfully apply security descriptors
313 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
314 2013.1.13 or earlier.
316 `wimlib-imagex capture' can now accept the '--delta-from' option
320 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
321 to standard output and applying images from standard input, but they are
322 not compatible with Microsoft's software and are not created by default.
323 See the documentation for --pipable flag of `wimlib-imagex capture' for
326 To better support incremental backups, added support for declaring an
327 image as a modified form of another image. See the documentation for
328 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
331 Added supported for "delta" WIMs. See the documentation for the
332 '--delta-from' option of `wimlib-imagex capture'.
334 The library support for managing split WIMs has been changed to support
335 other arrangements, such as delta WIMs, and be easier to use. This
336 change is visible in `wimlib-imagex', which also can now accept the
337 '--ref' option multiple times, and also now supports "delta" WIMs as
340 wimlib now preserves WIM integrity tables by default, even if
341 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
342 behavior of `wimlib-imagex' whenever the WIM being operated on contains
343 an integrity table and the '--check' option is not specified.
345 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
346 (when --compress is not specified). This provides the best compression
347 ratio by default, which is usually what is desired, at a cost of some
350 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
351 is the command as in `wimlib-imagex COMMAND'; for example, it can be
352 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
353 appropriate hard links are created in UNIX installations of
354 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
355 batch files that emulate this behavior are generated.
357 Security descriptors are now extracted correctly on Windows.
359 Fixed archiving DOS names in NTFS-3g capture mode.
361 The extraction code has been rewritten and it will now be easier to
362 support new features on all supported backends (currently Win32, UNIX,
363 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
364 now supported on all backends, not just UNIX.
366 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
367 than the WAIK itself.
369 wimlib_global_init() now, by default, attempts to acquire additional
370 privileges on Windows, so library clients need not do this.
372 This update bumps the shared library version number up to 9, since it is
373 not binary compatibible with previous releases.
376 Fixed bug in `wimlib-imagex export' that made it impossible to export an
377 image from a WIM that is readonly at the filesystem level.
379 Return error code rather than segfaulting when trying to list files from
380 a non-first part of a split WIM.
382 Joining a WIM will now preserve the RP_FIX and READONLY flags.
385 On Windows, paths given to wimlib-imagex are now treated case
388 Improved behavior regarding invalid filenames; in particular, on
389 Windows, wimlib-imagex will, when extracting, now omit (with an option
390 to override this default) filenames differing only in case, or filenames
391 containing characters not valid on Windows.
393 On Windows, wimlib now supports capturing and extracting long paths
394 (longer than the so-called MAX_PATH).
396 On Windows, `wimlib-imagex update' now acquires proper privileges when
397 running as an Administrator.
399 `wimlib-imagex update' will now complain if no image is specified when
400 trying to update a multi-image WIM.
402 `wimlib-imagex update' now supports specifying a single update command
403 directly on the command line using the --command option.
405 wimlib-imagex will now choose different units for progress messages,
406 depending on the amount of data that needs to be processed.
408 `wimlib-imagex append' will now generate a unique WIM image name if no
409 name is specified and the defaulted name already exists in the WIM.
411 wimlib now allows you to create unnamed WIM images, which can then only
412 be referred to by index.
414 wimlib now allows you to explicitly declare you want write access to a
415 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
418 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
421 Progress callbacks have been added to wimlib's wimlib_update_image()
424 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
425 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
428 NTFS-3g capture now only warns about two conditions previously treated
431 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
434 wimlib now correctly detects and returns an error when reading a WIM
435 image with a cyclic directory structure. (Fun fact: such a WIM will
436 crash Microsoft's software.)
439 Added new "extract" and "update" subcommands to wimlib-imagex, along
440 with associated APIs in the library. These commands are intended mainly
441 for Windows use but can be used on UNIX as well.
443 Many documentation improvements.
445 Fixed a bug in the Windows build where relative symbolic links were not
446 captured in reparse-point fixup mode.
448 Fixed a bug in the Windows build where file handles were left open to
449 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
451 Fixed a bug in the Windows build of wimlib-imagex where globbing
452 split-WIM parts could cause the program to crash.
454 Fixed a bug where the creation time of WIM images would be shown instead
455 of the last modification time.
457 With the Windows build it is now possible to restore a WIM containing
458 symbolic links as a non-Administrator; however you will receive warnings
459 about not being able to extract the symbolic links.
462 Capturing a WIM image should now be significantly faster in most cases
463 due to improved use of the operating system's cache and avoiding reading
464 files twice whenever possible.
466 The Windows build should now work on Windows XP.
468 The Windows build now supports capturing and restoring hidden,
469 compressed, sparse, and encrypted files.
471 The Windows build now supports capturing and applying WIM images from
472 filesystems other than NTFS (with some reduced functionality).
474 The Windows build now extracts short names correctly.
476 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
477 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
478 capture' and `wimlib-imagex apply'.
480 The performance of splitting and joining WIMs should be slightly
483 The LZX and XPRESS compression and decompression functions are now
484 exported from the library.
487 Improvements and bugfixes for the Windows build.
489 Added --strict-acls options.
491 Fixed the way that wimlib determines the order of images in the WIM.
494 Since wimlib can now be used on Windows, wimlib's implementation of
495 ImageX has been renamed to wimlib-imagex to avoid confusion with
496 Microsoft's implementation of ImageX, which would have the same file
497 name ("imagex.exe"). If you really don't like this you can pass the
498 --with-imagex-progname option to `configure' to choose a different name,
499 or even simply rename the binary yourself (but the former way will
500 configure the man pages to use the chosen name).
502 Various bugs fixed in the Windows build. Mainly to do with capturing
503 and restoring alternate data streams correctly in weird cases, and
504 requesting the correct privileges when opening files. Also added the
505 --noacls options to wimlib-imagex capture, append, and apply.
507 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
508 dynamically loaded, so this may make the library compatible with Windows
509 XP (however, there may still be other problems).
512 Added experimental support for native Windows builds. Binaries can be
513 downloaded from the SourceForge page.
515 --source-list option added to `imagex capture' and `imagex append'.
517 Better support for different character encodings.
520 Storing UNIX file owners, groups, and modes in WIM images is now
521 possible using `imagex capture' with the --unix-data flag.
523 Minor bug fixes and documentation fixes.
526 NTFS capture: Fixed capturing duplicate reparse points.
528 NTFS capture: Capture first unnamed stream if there are more than one
529 (print warning instead of error).
531 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
534 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
537 Update to work with ntfs-3g version 2013.1.13.
540 Fixed truncating file to shorter but non-zero length on read-write
543 Various code cleanups and minor documentation fixes.
546 LZX and XPRESS decompression have received some additional optimizations
547 and should now be even faster. (Although, they were already pretty
548 fast--- much faster than typical I/O speeds.)
550 Fixed a bug introduced in v1.2.1 that would cause a directory tree
551 containing hard links to be captured incorrectly in some cases.
554 By default, unmounting a read-write mounted WIM with 'imagex unmount
555 --commit' will now change the WIM in-place without needing to write the
556 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
559 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
560 for a response from the daemon servicing the mounted WIM. Instead,
561 every second 'imagex unmount' will check if the daemon is still alive,
562 and keep waiting if so, otherwise terminate with an error.
564 'imagex unmount --commit' on a read-write mounted WIM will now print
565 progress information regarding the writing of new or modified streams
566 the WIM, just like when capturing or appending a WIM.
568 A small change has been made to XPRESS compression and it should improve
569 the compression ratio slightly.
571 A change was made that may improve performance slightly when applying a
572 WIM image to a NTFS volume.
574 Microsoft has managed to introduce even more bugs into their software,
575 and now the WIMs for Windows 8 have incorrect (too low) reference counts
576 for some streams. This is unsafe because such streams can be removed
577 when they are in actuality still referenced in the WIM (perhaps by a
578 different image). wimlib will now work around this problem by fixing
579 the stream reference counts. This is only done when wimlib_delete_image() is
580 called ('imagex delete') or when wimlib_mount_image() is called with
581 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
582 requires reading the metadata for all images in the WIM, so this will
583 make these operations noticably slower on WIMs with multiple images.
585 Various other bugfixes.
588 Appending images to a WIM is now be done by default without re-building
589 the whole WIM. Use the --rebuild flag to get the old behavior (which
590 was to re-build the entire WIM when a new image is appended).
592 A new command `imagex optimize' is now available to manually re-build a
593 WIM that has wasted space due to repeated appends.
595 Progress information has been improved, and now arbitrary callback
596 functions can be used to show the progress of a WIM operation.
598 A possible bug with changing the bootable image of a WIM was fixed.
600 Some advisory locking is now done to prevent two processes from
601 modifying a WIM at the same time (but only in some cases). For example,
602 you cannot mount two images from a WIM read-write at the same time.
604 Some functions have been reorganized:
605 * wimlib_mount() renamed to wimlib_mount_image().
606 * wimlib_unmount() renamed to wimlib_unmount_image().
607 * wimlib_overwrite_xml_and_header() removed as
608 wimlib_overwrite() suffices now.
609 * wimlib_apply_image_to_ntfs_volume() removed as
610 wimlib_extract_image() suffices now.
611 * wimlib_add_image_from_ntfs_volume() removed as
612 * wimlib_add_image() suffices now.
614 Previously, the soname of libwim.so has been 0.0.0, despite many
615 interface changes. The soname is now updated to 1.0.0 and will now be
616 updated each release.
619 Resources will now be compressed using multiple threads by default.
620 (This applies to `imagex capture', `imagex append', and `imagex
623 Some performance improvements in mounted WIMs.
625 More progress information is shown when capturing a WIM.
628 Lots of minor fixes, code cleanups, and some documentation updates.
629 Nothing in particular is really noteworthy.
632 LZX and XPRESS compression improvements.
634 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
635 Link Bytes of the WIM.
638 Fixed bug when capturing NTFS file with multiple named data streams.
640 Internally, we are now using inode structures, even though these don't
641 appear literally in the WIM file. This simplifies some of the code
642 (mainly for WIM mounting) and likely fixed a few problems, although it
646 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
650 Enough changes to call it version 1.0.0!
652 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
653 to a NTFS volume, is now supported.
655 Hard links and symbolic links have much improved support. They are
656 supported for WIM capture, WIM application, and mounted WIMs (you can

659 Alternate data streams are now supported on mounted WIMs through an
660 xattr or a Windows-style stream interface. Also they are supported when
661 capturing a WIM from NTFS or applying a WIM to NTFS.
663 Split WIMs are better supported. You may now apply an image directly
664 from a split WIM, mount an image from a split WIM read-only, or export
665 an image from a split WIM.
667 Using a capture configuration file is now supported (but not fully yet).

678 Support for joining and splitting WIMs.
679 Also, security data is now preserved by default.
682 Can now build with older gcc and system headers, like on CentOS 5.
