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