2 More compression performance improvements.
4 Fixes for setting short names on Windows.
6 Faster "WIMBoot" extraction on Windows.
8 Updated dependent DLLs in Windows release. libxml2 is slimmed down.
11 Added file count progress data for
12 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
13 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
15 Added support for testing file exclusions via the user-provided
18 Some documentation improvements.
21 Made more improvements to the XPRESS, LZX, and LZMS compressors.
23 The default compression mode for wimcapture is now LZX compression in
24 its default mode, which is the same as '--compress=maximum'.
26 You can now specify an optional integer compression level to the
27 '--compress' option; e.g. '--compress=lzx:75'.
29 Made a minor change to the LZMS compressor and decompressor to fix an
30 incompatibility with the Microsoft implementation. In the unlikely
31 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
32 earlier and a checksum error is reported when extracting files from it
33 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
36 Added 'verify' subcommand to wimlib-imagex.
38 Notable library changes:
40 Custom compressor parameters have been removed from the library
41 in favor of the simpler level-based API.
43 Decompressor parameters have been removed entirely.
45 Library users can now specify a custom file for warning and
46 error messages to be sent to, rather than the default of
49 New progress messages:
50 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
51 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
53 New function: wimlib_verify_wim().
56 Improved compression, decompression, and extraction performance.
58 Improved compatibility with version 3584 WIM / ESD files:
59 - Add support for reading and writing multiple solid blocks per
60 archive, which WIMGAPI/DISM can create when appending an image.
61 - Correctly create solid blocks larger than 4 GiB.
63 'add' commands passed to wimupdate will now replace existing
64 nondirectory files by default. Use the --no-replace option to get the
67 The license for the library now contains an exception that allows using
68 it under the LGPL. See the COPYING file for details.
70 In reparse-point fixup mode (the default for capture), symbolic links
71 and junctions that point outside the tree being captured are no longer
72 excluded from capture.
74 Added support for "WIMBoot" capture and extraction. See the
75 documentation for the new '--wimboot' option to wimcapture and wimapply
78 On UNIX-like systems, you can now backup and restore device nodes, named
79 pipes, and sockets. In addition, 32-bit user and group IDs are now
82 The way that UNIX data is stored in WIM files has been changed. If you
83 captured any WIMs with the --unix-data option, to upgrade them you'll
84 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
85 re-capture them with --unix-data using this version.
87 wimlib now understands tagged metadata items, such as object IDs, that
88 can be stored in WIM directory entries.
90 Removed the --hardlink and --symlink options to wimapply, since I don't
91 think they are too useful and they got in the way of improving the code.
93 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
95 The 'mkwinpeimg' script now supports writing the ISO image to standard
98 The <ARCH> element in WIM XML data is now exported correctly.
100 On Windows, sparse file attributes are no longer set on extracted files.
101 Oddly enough, this actually saves disk space in some cases.
103 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
104 supported. Mounting WIM images now always requires extended attribute
105 support. Use --without-fuse to disable support for mounting WIM images;
106 this will also disable the need for extended attribute support.
108 Configuring with --enable-ssse3-sha1 now works correctly.
110 The shared library version has been bumped up. The main
111 incompatibilities are:
113 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
114 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
117 - User-provided progress functions are now registered using a
118 separate function, wimlib_register_progress_function(). The
119 'progress_func' argument to many functions no longer exists.
121 - The return value from user-provided progress functions is now
124 - A context argument has been added to the prototype of
125 user-provided progress functions.
127 - 'struct wimlib_capture_config' has been removed. The library
128 now takes the path to the configuration file directly. This
129 affects wimlib_add_image(), wimlib_add_image_multisource(),
130 and wimlib_update_image(). However, a NULL value passed in
131 the argument retains the same meaning.
133 - Removed deprecated functions: some (de)compression functions,
134 wimlib_extract_files(), and wimlib_print_metadata().
136 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
137 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
138 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
140 - Removed some progress messages:
141 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
142 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
143 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
146 - Removed some error codes. Numbering stays the same.
148 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
149 WIMLIB_UNMOUNT_FLAG_FORCE.
151 - WIM paths passed to progress functions now have a leading
155 Case-insensitive comparisons of strings (e.g. filenames) containing
156 UTF-16 codepoints above 32767 are now done correctly.
158 Fixed build failure on Mac OS X.
160 wimunmount now provides the '--new-image' option to cause changes to a
161 read-write mounted image to be committed as a new image rather than as
162 an update of the mounted image. (The corresponding new library flag is
163 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
165 The LZMS ("recovery") compression chunk size, or "dictionary size", may
166 now be up to 1 GiB (1,073,741,824 bytes).
168 The performance of LZX ("maximum") and LZMS ("recovery") compression
169 with large chunk sizes has been slightly improved.
172 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
173 decompressed correctly.
175 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
176 occurred in an unlikely case, and due to validity checks it did not
177 affect successfully created archives.
179 Fixed a minor compatibility issue with the LZMS compressor and
180 decompressor. This is *not* the default compression type and was only
181 introduced in v1.6.0. In the unlikely event that you created an
182 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
183 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
186 Memory usage for LZMS and LZX compression has been decreased.
188 wimextract now allows wildcard characters in paths specified on the
189 command line. Also, the '--strict-wildcards' option has been removed
190 and replaced with the inverse option '--nullglob'. See the
191 documentation for wimextract for more details and changes.
193 The wimlib_extract_files() function is now considered deprecated in
194 favor of wimlib_extract_paths().
196 Fixed more permissions problems when extracting files on Windows.
198 A new '--no-attributes' option has been added to wimapply and
199 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
201 The default chunk size is now set correctly when changing the
202 compression type of a WIM, for example with 'wimoptimize'.
204 The '--metadata' option to wiminfo has been replaced with the
205 '--detailed' option to wimdir.
207 In relevant wimlib-imagex commands, '--solid' may now be used as an
208 alias for '--pack-streams'.
211 Support for extracting and updating the new version 3584 WIMs has been
212 added. These WIMs typically pack many streams ("files") together into a
213 single compressed resource, thereby saving space. This degrades the
214 performance of random access (such as that which occurs on a mounted
215 image), but optimizations have been implemented for extraction. These
216 new WIM files also typically use a new compression format (LZMS), which
217 is similar to LZMA and can offer a better compression ratio than LZX.
218 These new WIM files can be created using `wimcapture' with
219 the '--compress=lzms --pack-streams' options. Note: this new WIM format
220 is used by the Windows 8 web downloader, but important segments of the
221 raw '.esd' files are encrypted, so wimlib will not be able to extract
222 such files until they are first decrypted.
224 wimlib now supports extracting files and directories from a WIM image
225 based on a "listfile" that itself contains the list of paths to extract.
226 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
227 and for the library itself, the new APIs are wimlib_extract_pathlist()
228 and wimlib_extract_paths(). Path globs containing wildcard characters
231 For searching WIM files, wimlib now has configurable case sensitivity.
232 The default on Windows is still case-insensitive and the default on
233 UNIX-like systems is still case-sensitive, but this can be overridden
234 on either platform through flags to wimlib_global_init(). For
235 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
236 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
239 Support for compression chunk sizes greater than the default of 32768
240 bytes has been added. A larger chunk size typically results in a better
241 compression ratio. However, the MS implementation is seemingly not
242 compatible with all chunk sizes, especially for LZX compression, so the
243 defaults remain unchanged, with the exception of the new LZMS-compressed
244 WIMs, which use a larger chunk size by default.
246 The compression/decompression API exported by wimlib has been changed.
247 Now one set of functions handles all supported compression formats.
249 `wimcapture' and `wimappend' will now display the progress of scanning
250 the directory tree to capture, in addition to the progress of writing
251 data to the WIM. The '--verbose' option no longer does anything. The
252 library API change for this is the addition of several members to
253 `struct wimlib_progress_info_scan' available to progress callbacks.
255 `mkwinpeimg' now correctly handles the '--start-script' option when the
256 start script is not in the working directory.
258 Sequential extraction, previously requested by using
259 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
260 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
261 behavior (extract in file order).
264 The new LZX compressor added in v1.5.2 has been improved and is now
265 enabled by default, except when `wimcapture' or `wimappend' is run
266 *without* the '--compress' option, in which case the faster LZX
267 compressor is used (the same as before). This behavior is reasonably
268 consistent with ImageX which actually uses "fast" (XPRESS) compression
269 by default. In those cases, use '--compress=maximum' to explicitly
270 capture a WIM image using the new (slower but better) LZX compressor.
272 The '--compress-slow' option still exists to `wimlib-imagex optimize',
273 but its new behavior is to tweak the new LZX compressor even more to
274 produce an even better compression ratio at the cost of more time spent
277 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
278 which recompresses the WIM file using the specified compression TYPE.
279 The new library API function used for this is
280 wimlib_set_output_compression_type().
282 Added the wimlib_get_xml_data() function to allow library clients to
283 easily retrieve the raw XML data from a WIM file if needed.
285 Fixed a bug that could cause an error code to be incorrectly returned
286 when writing XML data containing a <WINDOWS> element.
288 Mounted WIM images will now correctly show the default file stream even
289 if appears in the alternate data stream entries of the corresponding WIM
293 Added a new experimental LZX compressor which can be enabled by passing
294 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
295 optimize'. (The latter is only applicable if the WIM is already
296 LZX-compressed and the '--recompress' option is also given.) The
297 experimental compressor is much slower but compresses the data slightly
298 more --- currently usually to within a fraction of a percent of the
299 results from WIMGAPI/ImageX.
301 A workaround has been added for compatibility with versions of WinPE
302 that interpret alternate data stream entries in the boot WIM
305 An alignment bug that caused a crash in the LZX decompressor on some
308 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
309 the WIM header when restoring the previous state of a WIM it failed to
312 Added a workaround to avoid an access denied error on Windows when
313 replacing a WIM file that another process has opened.
316 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
317 needed to be handled.
319 A bug in the interpretation of negative IMAGE indices in the
320 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
321 `wimlib-imagex append' has been fixed.
323 A workaround has been added to successfully apply security descriptors
324 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
325 2013.1.13 or earlier.
327 `wimlib-imagex capture' can now accept the '--delta-from' option
331 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
332 to standard output and applying images from standard input, but they are
333 not compatible with Microsoft's software and are not created by default.
334 See the documentation for --pipable flag of `wimlib-imagex capture' for
337 To better support incremental backups, added support for declaring an
338 image as a modified form of another image. See the documentation for
339 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
342 Added supported for "delta" WIMs. See the documentation for the
343 '--delta-from' option of `wimlib-imagex capture'.
345 The library support for managing split WIMs has been changed to support
346 other arrangements, such as delta WIMs, and be easier to use. This
347 change is visible in `wimlib-imagex', which also can now accept the
348 '--ref' option multiple times, and also now supports "delta" WIMs as
351 wimlib now preserves WIM integrity tables by default, even if
352 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
353 behavior of `wimlib-imagex' whenever the WIM being operated on contains
354 an integrity table and the '--check' option is not specified.
356 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
357 (when --compress is not specified). This provides the best compression
358 ratio by default, which is usually what is desired, at a cost of some
361 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
362 is the command as in `wimlib-imagex COMMAND'; for example, it can be
363 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
364 appropriate hard links are created in UNIX installations of
365 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
366 batch files that emulate this behavior are generated.
368 Security descriptors are now extracted correctly on Windows.
370 Fixed archiving DOS names in NTFS-3g capture mode.
372 The extraction code has been rewritten and it will now be easier to
373 support new features on all supported backends (currently Win32, UNIX,
374 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
375 now supported on all backends, not just UNIX.
377 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
378 than the WAIK itself.
380 wimlib_global_init() now, by default, attempts to acquire additional
381 privileges on Windows, so library clients need not do this.
383 This update bumps the shared library version number up to 9, since it is
384 not binary compatibible with previous releases.
387 Fixed bug in `wimlib-imagex export' that made it impossible to export an
388 image from a WIM that is readonly at the filesystem level.
390 Return error code rather than segfaulting when trying to list files from
391 a non-first part of a split WIM.
393 Joining a WIM will now preserve the RP_FIX and READONLY flags.
396 On Windows, paths given to wimlib-imagex are now treated case
399 Improved behavior regarding invalid filenames; in particular, on
400 Windows, wimlib-imagex will, when extracting, now omit (with an option
401 to override this default) filenames differing only in case, or filenames
402 containing characters not valid on Windows.
404 On Windows, wimlib now supports capturing and extracting long paths
405 (longer than the so-called MAX_PATH).
407 On Windows, `wimlib-imagex update' now acquires proper privileges when
408 running as an Administrator.
410 `wimlib-imagex update' will now complain if no image is specified when
411 trying to update a multi-image WIM.
413 `wimlib-imagex update' now supports specifying a single update command
414 directly on the command line using the --command option.
416 wimlib-imagex will now choose different units for progress messages,
417 depending on the amount of data that needs to be processed.
419 `wimlib-imagex append' will now generate a unique WIM image name if no
420 name is specified and the defaulted name already exists in the WIM.
422 wimlib now allows you to create unnamed WIM images, which can then only
423 be referred to by index.
425 wimlib now allows you to explicitly declare you want write access to a
426 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
429 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
432 Progress callbacks have been added to wimlib's wimlib_update_image()
435 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
436 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
439 NTFS-3g capture now only warns about two conditions previously treated
442 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
445 wimlib now correctly detects and returns an error when reading a WIM
446 image with a cyclic directory structure. (Fun fact: such a WIM will
447 crash Microsoft's software.)
450 Added new "extract" and "update" subcommands to wimlib-imagex, along
451 with associated APIs in the library. These commands are intended mainly
452 for Windows use but can be used on UNIX as well.
454 Many documentation improvements.
456 Fixed a bug in the Windows build where relative symbolic links were not
457 captured in reparse-point fixup mode.
459 Fixed a bug in the Windows build where file handles were left open to
460 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
462 Fixed a bug in the Windows build of wimlib-imagex where globbing
463 split-WIM parts could cause the program to crash.
465 Fixed a bug where the creation time of WIM images would be shown instead
466 of the last modification time.
468 With the Windows build it is now possible to restore a WIM containing
469 symbolic links as a non-Administrator; however you will receive warnings
470 about not being able to extract the symbolic links.
473 Capturing a WIM image should now be significantly faster in most cases
474 due to improved use of the operating system's cache and avoiding reading
475 files twice whenever possible.
477 The Windows build should now work on Windows XP.
479 The Windows build now supports capturing and restoring hidden,
480 compressed, sparse, and encrypted files.
482 The Windows build now supports capturing and applying WIM images from
483 filesystems other than NTFS (with some reduced functionality).
485 The Windows build now extracts short names correctly.
487 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
488 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
489 capture' and `wimlib-imagex apply'.
491 The performance of splitting and joining WIMs should be slightly
494 The LZX and XPRESS compression and decompression functions are now
495 exported from the library.
498 Improvements and bugfixes for the Windows build.
500 Added --strict-acls options.
502 Fixed the way that wimlib determines the order of images in the WIM.
505 Since wimlib can now be used on Windows, wimlib's implementation of
506 ImageX has been renamed to wimlib-imagex to avoid confusion with
507 Microsoft's implementation of ImageX, which would have the same file
508 name ("imagex.exe"). If you really don't like this you can pass the
509 --with-imagex-progname option to `configure' to choose a different name,
510 or even simply rename the binary yourself (but the former way will
511 configure the man pages to use the chosen name).
513 Various bugs fixed in the Windows build. Mainly to do with capturing
514 and restoring alternate data streams correctly in weird cases, and
515 requesting the correct privileges when opening files. Also added the
516 --noacls options to wimlib-imagex capture, append, and apply.
518 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
519 dynamically loaded, so this may make the library compatible with Windows
520 XP (however, there may still be other problems).
523 Added experimental support for native Windows builds. Binaries can be
524 downloaded from the SourceForge page.
526 --source-list option added to `imagex capture' and `imagex append'.
528 Better support for different character encodings.
531 Storing UNIX file owners, groups, and modes in WIM images is now
532 possible using `imagex capture' with the --unix-data flag.
534 Minor bug fixes and documentation fixes.
537 NTFS capture: Fixed capturing duplicate reparse points.
539 NTFS capture: Capture first unnamed stream if there are more than one
540 (print warning instead of error).
542 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
545 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
548 Update to work with ntfs-3g version 2013.1.13.
551 Fixed truncating file to shorter but non-zero length on read-write
554 Various code cleanups and minor documentation fixes.
557 LZX and XPRESS decompression have received some additional optimizations
558 and should now be even faster. (Although, they were already pretty
559 fast--- much faster than typical I/O speeds.)
561 Fixed a bug introduced in v1.2.1 that would cause a directory tree
562 containing hard links to be captured incorrectly in some cases.
565 By default, unmounting a read-write mounted WIM with 'imagex unmount
566 --commit' will now change the WIM in-place without needing to write the
567 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
570 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
571 for a response from the daemon servicing the mounted WIM. Instead,
572 every second 'imagex unmount' will check if the daemon is still alive,
573 and keep waiting if so, otherwise terminate with an error.
575 'imagex unmount --commit' on a read-write mounted WIM will now print
576 progress information regarding the writing of new or modified streams
577 the WIM, just like when capturing or appending a WIM.
579 A small change has been made to XPRESS compression and it should improve
580 the compression ratio slightly.
582 A change was made that may improve performance slightly when applying a
583 WIM image to a NTFS volume.
585 Microsoft has managed to introduce even more bugs into their software,
586 and now the WIMs for Windows 8 have incorrect (too low) reference counts
587 for some streams. This is unsafe because such streams can be removed
588 when they are in actuality still referenced in the WIM (perhaps by a
589 different image). wimlib will now work around this problem by fixing
590 the stream reference counts. This is only done when wimlib_delete_image() is
591 called ('imagex delete') or when wimlib_mount_image() is called with
592 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
593 requires reading the metadata for all images in the WIM, so this will
594 make these operations noticably slower on WIMs with multiple images.
596 Various other bugfixes.
599 Appending images to a WIM is now be done by default without re-building
600 the whole WIM. Use the --rebuild flag to get the old behavior (which
601 was to re-build the entire WIM when a new image is appended).
603 A new command `imagex optimize' is now available to manually re-build a
604 WIM that has wasted space due to repeated appends.
606 Progress information has been improved, and now arbitrary callback
607 functions can be used to show the progress of a WIM operation.
609 A possible bug with changing the bootable image of a WIM was fixed.
611 Some advisory locking is now done to prevent two processes from
612 modifying a WIM at the same time (but only in some cases). For example,
613 you cannot mount two images from a WIM read-write at the same time.
615 Some functions have been reorganized:
616 * wimlib_mount() renamed to wimlib_mount_image().
617 * wimlib_unmount() renamed to wimlib_unmount_image().
618 * wimlib_overwrite_xml_and_header() removed as
619 wimlib_overwrite() suffices now.
620 * wimlib_apply_image_to_ntfs_volume() removed as
621 wimlib_extract_image() suffices now.
622 * wimlib_add_image_from_ntfs_volume() removed as
623 * wimlib_add_image() suffices now.
625 Previously, the soname of libwim.so has been 0.0.0, despite many
626 interface changes. The soname is now updated to 1.0.0 and will now be
627 updated each release.
630 Resources will now be compressed using multiple threads by default.
631 (This applies to `imagex capture', `imagex append', and `imagex
634 Some performance improvements in mounted WIMs.
636 More progress information is shown when capturing a WIM.
639 Lots of minor fixes, code cleanups, and some documentation updates.
640 Nothing in particular is really noteworthy.
643 LZX and XPRESS compression improvements.
645 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
646 Link Bytes of the WIM.
649 Fixed bug when capturing NTFS file with multiple named data streams.
651 Internally, we are now using inode structures, even though these don't
652 appear literally in the WIM file. This simplifies some of the code
