2 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
3 some Microsoft software would not correctly recognize data in the
4 resulting filesystem. Users of the (UNIX-only) NTFS-3g based WIM
5 extraction support should not use wimlib v1.8.1 or wimlib v1.8.2.
8 This release primarily contains various minor bug fixes and
9 improvements, including:
11 Improved handling of deep directory structures.
13 Fixed a bug where on 32-bit systems, the library could enter an
14 infinite loop if a WIM file was malformed in a specific way.
16 Added a workaround for a case where libntfs-3g may report
17 duplicate streams in an NTFS file.
19 Windows symbolic links and junctions in mounted WIM images are
20 now automatically rewritten to be valid in the mounted location.
22 Reparse point fixes: correctly handle the "ReparseReserved"
23 field, and correctly handle "empty" (data-less) reparse points.
25 On Windows, wimlib now acquires SeManageVolumePrivilege, which
26 is needed to create externally backed files using the
29 Improved validation of filenames.
31 Improved LZMS decompression speed.
33 The configure script now honors alternate pkg-config settings.
35 Links have been updated to point to the new website.
37 In addition, experimental support has been added for compressing
38 extracted files using System Compression on Windows 10. This
39 functionality is available through the new '--compact' option to
40 'wimapply' and 'wimextract' as well as new library flags.
43 Fixed a bug in the LZX decompressor: malicious input data could cause
44 out of bounds writes to memory (since wimlib v1.2.2).
46 The output of the 'wiminfo' command now consolidates various boolean
47 flags (such as "Relative path junction") into a single line.
49 A file can now have both an unnamed data stream ("file contents") and a
50 reparse point stream. Such files can exist as a result of the use of
51 certain Windows features, such as offline storage, including "OneDrive".
52 wimlib will now store and restore both streams on Windows as well as in
53 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
55 On Windows, named data streams of encrypted files are no longer stored
56 twice in WIM archives.
58 On Windows, named data streams are now correctly extracted to existing
59 "readonly" directories. Before, an error would be reported.
61 On Windows, it is now possible to do a "WIMBoot mode" extraction with
62 non-standalone WIMs such as delta WIMs.
64 On Windows, when doing an extraction in "WIMBoot mode", files larger
65 than 4 gigabytes are now never extracted as externally backed. This
66 works around a bug in Microsoft's "WOF" driver.
68 The '--enable-verify-compression' configure option has been removed. If
69 you want to verify a WIM file, use the 'wimverify' program.
71 The way the "file count", "directory count", "total bytes", and "hard
72 link bytes" image statistics (stored in the WIM XML data) is calculated
73 has been slightly changed.
75 In mounted WIM images, the disk usage provided for each file (st_blocks)
76 is now the compressed size rather than the uncompressed size.
78 The performance of the NTFS-3g and Windows capture modes has been
81 On UNIX-like systems, symbolic links whose targets contain the backslash
82 character are now handled correctly (losslessly).
85 Improved the LZX compressor. It is now 15-20% faster than before and
86 provides a slightly better compression ratio.
88 Improved the LZMS compressor. It now provides a compression ratio
89 slightly better than WIMGAPI while still being faster and using slightly
92 The compression chunk size in solid resources, e.g. when capturing or
93 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
94 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
95 better compression ratio and is the same value that WIMGAPI uses. The
96 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
97 lower than WIMGAPI's memory usage, but if it is too much, it is still
98 possible to choose a lower value, e.g. with the '--solid-chunk-size'
99 option to wimlib-imagex.
101 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
102 accept the 'K', 'M', and 'G' suffixes.
104 Files are now sorted by name extension when creating a solid WIM file.
106 Fixed various issues related to capture/apply of EFS-encrypted files on
109 The file list printed by 'wimdir' is now sorted by the platform-specific
110 case sensitivity setting, rather than always case sensitively. This
111 also affects the library function wimlib_iterate_dir_tree().
113 On Windows, some error and warning messages have been improved.
116 The Windows binary distribution no longer contains third party DLLs.
117 These dependencies are instead compiled directly into the libwim DLL.
119 Added more fixes for wimlib on non-x86 architectures such as ARM.
121 Extracting files to a Windows PE in-memory filesystem no longer fails if
122 the target files do not yet exist.
124 Improved the performance of XPRESS compression and LZMS decompression.
126 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
127 It will automatically be faster on newer Intel and AMD processors.
129 Removed the --with-imagex-progname and --enable-more-assertions
133 Fix for very slow export from solid WIM / ESD files.
135 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
137 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
138 may use this to treat some types of errors as non-fatal.
140 The library now permits making in-memory changes to a WIMStruct backed
141 by a read-only WIM file.
143 Fixes for "WIMBoot" extraction mode (Windows only):
145 When not using the WOF driver, extraction no longer fails if the
146 disk containing the WIM file has too many partitions.
148 When matching patterns in [PrepopulateList], all hard links of
149 each file are now considered.
151 The system registry files are now automatically treated as being
152 in [PrepopulateList].
154 Added a hack to try to work around an intermittent bug in
155 Microsoft's WOF (Windows Overlay Filesystem) driver.
158 Made more improvements to the XPRESS, LZX, and LZMS compressors.
160 A number of improvements to the Windows port:
162 Fixes for setting short filenames.
164 Faster "WIMBoot" extraction.
166 Updated and slimmed down the dependent DLLs.
168 ACL inheritence bits are now restored.
170 Mandatory integrity labels are now backed up and restored.
172 Added a workaround for an issue where in rare cases, wimlib could create
173 a compressed data stream that could not be read correctly by Windows
174 after an extraction in "WIMBoot" mode.
177 Added file count progress data for
178 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
179 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
181 Added support for testing file exclusions via the user-provided
184 Some documentation improvements.
186 Made some clarifications to the license text in the COPYING file.
189 Made more improvements to the XPRESS, LZX, and LZMS compressors.
191 The default compression mode for wimcapture is now LZX compression in
192 its default mode, which is the same as '--compress=maximum'.
194 You can now specify an optional integer compression level to the
195 '--compress' option; e.g. '--compress=lzx:75'.
197 Made a minor change to the LZMS compressor and decompressor to fix an
198 incompatibility with the Microsoft implementation. In the unlikely
199 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
200 earlier and a checksum error is reported when extracting files from it
201 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
204 Added 'verify' subcommand to wimlib-imagex.
206 Notable library changes:
208 Custom compressor parameters have been removed from the library
209 in favor of the simpler level-based API.
211 Decompressor parameters have been removed entirely.
213 Library users can now specify a custom file for warning and
214 error messages to be sent to, rather than the default of
217 New progress messages:
218 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
219 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
221 New function: wimlib_verify_wim().
224 Improved compression, decompression, and extraction performance.
226 Improved compatibility with version 3584 WIM / ESD files:
227 - Add support for reading and writing multiple solid blocks per
228 archive, which WIMGAPI/DISM can create when appending an image.
229 - Correctly create solid blocks larger than 4 GiB.
231 'add' commands passed to wimupdate will now replace existing
232 nondirectory files by default. Use the --no-replace option to get the
235 The license for the library now contains an exception that allows using
236 it under the LGPL. See the COPYING file for details.
238 In reparse-point fixup mode (the default for capture), symbolic links
239 and junctions that point outside the tree being captured are no longer
240 excluded from capture.
242 Added support for "WIMBoot" capture and extraction. See the
243 documentation for the new '--wimboot' option to wimcapture and wimapply
244 for more information.
246 On UNIX-like systems, you can now backup and restore device nodes, named
247 pipes, and sockets. In addition, 32-bit user and group IDs are now
250 The way that UNIX data is stored in WIM files has been changed. If you
251 captured any WIMs with the --unix-data option, to upgrade them you'll
252 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
253 re-capture them with --unix-data using this version.
255 wimlib now understands tagged metadata items, such as object IDs, that
256 can be stored in WIM directory entries.
258 Removed the --hardlink and --symlink options to wimapply, since I don't
259 think they are too useful and they got in the way of improving the code.
261 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
263 The 'mkwinpeimg' script now supports writing the ISO image to standard
266 The <ARCH> element in WIM XML data is now exported correctly.
268 On Windows, sparse file attributes are no longer set on extracted files.
269 Oddly enough, this actually saves disk space in some cases.
271 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
272 supported. Mounting WIM images now always requires extended attribute
273 support. Use --without-fuse to disable support for mounting WIM images;
274 this will also disable the need for extended attribute support.
276 Configuring with --enable-ssse3-sha1 now works correctly.
278 The shared library version has been bumped up. The main
279 incompatibilities are:
281 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
282 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
285 - User-provided progress functions are now registered using a
286 separate function, wimlib_register_progress_function(). The
287 'progress_func' argument to many functions no longer exists.
289 - The return value from user-provided progress functions is now
292 - A context argument has been added to the prototype of
293 user-provided progress functions.
295 - 'struct wimlib_capture_config' has been removed. The library
296 now takes the path to the configuration file directly. This
297 affects wimlib_add_image(), wimlib_add_image_multisource(),
298 and wimlib_update_image(). However, a NULL value passed in
299 the argument retains the same meaning.
301 - Removed deprecated functions: some (de)compression functions,
302 wimlib_extract_files(), and wimlib_print_metadata().
304 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
305 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
306 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
308 - Removed some progress messages:
309 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
310 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
311 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
314 - Removed some error codes. Numbering stays the same.
316 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
317 WIMLIB_UNMOUNT_FLAG_FORCE.
319 - WIM paths passed to progress functions now have a leading
323 Case-insensitive comparisons of strings (e.g. filenames) containing
324 UTF-16 codepoints above 32767 are now done correctly.
326 Fixed build failure on Mac OS X.
328 wimunmount now provides the '--new-image' option to cause changes to a
329 read-write mounted image to be committed as a new image rather than as
330 an update of the mounted image. (The corresponding new library flag is
331 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
333 The LZMS ("recovery") compression chunk size, or "dictionary size", may
334 now be up to 1 GiB (1,073,741,824 bytes).
336 The performance of LZX ("maximum") and LZMS ("recovery") compression
337 with large chunk sizes has been slightly improved.
340 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
341 decompressed correctly.
343 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
344 occurred in an unlikely case, and due to validity checks it did not
345 affect successfully created archives.
347 Fixed a minor compatibility issue with the LZMS compressor and
348 decompressor. This is *not* the default compression type and was only
349 introduced in v1.6.0. In the unlikely event that you created an
350 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
351 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
354 Memory usage for LZMS and LZX compression has been decreased.
356 wimextract now allows wildcard characters in paths specified on the
357 command line. Also, the '--strict-wildcards' option has been removed
358 and replaced with the inverse option '--nullglob'. See the
359 documentation for wimextract for more details and changes.
361 The wimlib_extract_files() function is now considered deprecated in
362 favor of wimlib_extract_paths().
364 Fixed more permissions problems when extracting files on Windows.
366 A new '--no-attributes' option has been added to wimapply and
367 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
369 The default chunk size is now set correctly when changing the
370 compression type of a WIM, for example with 'wimoptimize'.
372 The '--metadata' option to wiminfo has been replaced with the
373 '--detailed' option to wimdir.
375 In relevant wimlib-imagex commands, '--solid' may now be used as an
376 alias for '--pack-streams'.
379 Support for extracting and updating the new version 3584 WIMs has been
380 added. These WIMs typically pack many streams ("files") together into a
381 single compressed resource, thereby saving space. This degrades the
382 performance of random access (such as that which occurs on a mounted
383 image), but optimizations have been implemented for extraction. These
384 new WIM files also typically use a new compression format (LZMS), which
385 is similar to LZMA and can offer a better compression ratio than LZX.
386 These new WIM files can be created using `wimcapture' with
387 the '--compress=lzms --pack-streams' options. Note: this new WIM format
388 is used by the Windows 8 web downloader, but important segments of the
389 raw '.esd' files are encrypted, so wimlib will not be able to extract
390 such files until they are first decrypted.
392 wimlib now supports extracting files and directories from a WIM image
393 based on a "listfile" that itself contains the list of paths to extract.
394 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
395 and for the library itself, the new APIs are wimlib_extract_pathlist()
396 and wimlib_extract_paths(). Path globs containing wildcard characters
399 For searching WIM files, wimlib now has configurable case sensitivity.
400 The default on Windows is still case-insensitive and the default on
401 UNIX-like systems is still case-sensitive, but this can be overridden
402 on either platform through flags to wimlib_global_init(). For
403 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
404 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
407 Support for compression chunk sizes greater than the default of 32768
408 bytes has been added. A larger chunk size typically results in a better
409 compression ratio. However, the MS implementation is seemingly not
410 compatible with all chunk sizes, especially for LZX compression, so the
411 defaults remain unchanged, with the exception of the new LZMS-compressed
412 WIMs, which use a larger chunk size by default.
414 The compression/decompression API exported by wimlib has been changed.
415 Now one set of functions handles all supported compression formats.
417 `wimcapture' and `wimappend' will now display the progress of scanning
418 the directory tree to capture, in addition to the progress of writing
419 data to the WIM. The '--verbose' option no longer does anything. The
420 library API change for this is the addition of several members to
421 `struct wimlib_progress_info_scan' available to progress callbacks.
423 `mkwinpeimg' now correctly handles the '--start-script' option when the
424 start script is not in the working directory.
426 Sequential extraction, previously requested by using
427 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
428 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
429 behavior (extract in file order).
432 The new LZX compressor added in v1.5.2 has been improved and is now
433 enabled by default, except when `wimcapture' or `wimappend' is run
434 *without* the '--compress' option, in which case the faster LZX
435 compressor is used (the same as before). This behavior is reasonably
436 consistent with ImageX which actually uses "fast" (XPRESS) compression
437 by default. In those cases, use '--compress=maximum' to explicitly
438 capture a WIM image using the new (slower but better) LZX compressor.
440 The '--compress-slow' option still exists to `wimlib-imagex optimize',
441 but its new behavior is to tweak the new LZX compressor even more to
442 produce an even better compression ratio at the cost of more time spent
445 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
446 which recompresses the WIM file using the specified compression TYPE.
447 The new library API function used for this is
448 wimlib_set_output_compression_type().
450 Added the wimlib_get_xml_data() function to allow library clients to
451 easily retrieve the raw XML data from a WIM file if needed.
453 Fixed a bug that could cause an error code to be incorrectly returned
454 when writing XML data containing a <WINDOWS> element.
456 Mounted WIM images will now correctly show the default file stream even
457 if appears in the alternate data stream entries of the corresponding WIM
461 Added a new experimental LZX compressor which can be enabled by passing
462 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
463 optimize'. (The latter is only applicable if the WIM is already
464 LZX-compressed and the '--recompress' option is also given.) The
465 experimental compressor is much slower but compresses the data slightly
466 more --- currently usually to within a fraction of a percent of the
467 results from WIMGAPI/ImageX.
469 A workaround has been added for compatibility with versions of WinPE
470 that interpret alternate data stream entries in the boot WIM
473 An alignment bug that caused a crash in the LZX decompressor on some
476 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
477 the WIM header when restoring the previous state of a WIM it failed to
480 Added a workaround to avoid an access denied error on Windows when
481 replacing a WIM file that another process has opened.
484 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
485 needed to be handled.
487 A bug in the interpretation of negative IMAGE indices in the
488 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
489 `wimlib-imagex append' has been fixed.
491 A workaround has been added to successfully apply security descriptors
492 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
493 2013.1.13 or earlier.
495 `wimlib-imagex capture' can now accept the '--delta-from' option
499 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
500 to standard output and applying images from standard input, but they are
501 not compatible with Microsoft's software and are not created by default.
502 See the documentation for --pipable flag of `wimlib-imagex capture' for
505 To better support incremental backups, added support for declaring an
506 image as a modified form of another image. See the documentation for
507 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
510 Added supported for "delta" WIMs. See the documentation for the
511 '--delta-from' option of `wimlib-imagex capture'.
513 The library support for managing split WIMs has been changed to support
514 other arrangements, such as delta WIMs, and be easier to use. This
515 change is visible in `wimlib-imagex', which also can now accept the
516 '--ref' option multiple times, and also now supports "delta" WIMs as
519 wimlib now preserves WIM integrity tables by default, even if
520 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
521 behavior of `wimlib-imagex' whenever the WIM being operated on contains
522 an integrity table and the '--check' option is not specified.
524 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
525 (when --compress is not specified). This provides the best compression
526 ratio by default, which is usually what is desired, at a cost of some
529 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
530 is the command as in `wimlib-imagex COMMAND'; for example, it can be
531 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
532 appropriate hard links are created in UNIX installations of
533 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
534 batch files that emulate this behavior are generated.
536 Security descriptors are now extracted correctly on Windows.
538 Fixed archiving DOS names in NTFS-3g capture mode.
540 The extraction code has been rewritten and it will now be easier to
541 support new features on all supported backends (currently Win32, UNIX,
542 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
543 now supported on all backends, not just UNIX.
545 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
546 than the WAIK itself.
548 wimlib_global_init() now, by default, attempts to acquire additional
549 privileges on Windows, so library clients need not do this.
551 This update bumps the shared library version number up to 9, since it is
552 not binary compatibible with previous releases.
555 Fixed bug in `wimlib-imagex export' that made it impossible to export an
556 image from a WIM that is readonly at the filesystem level.
558 Return error code rather than segfaulting when trying to list files from
559 a non-first part of a split WIM.
561 Joining a WIM will now preserve the RP_FIX and READONLY flags.
564 On Windows, paths given to wimlib-imagex are now treated case
567 Improved behavior regarding invalid filenames; in particular, on
568 Windows, wimlib-imagex will, when extracting, now omit (with an option
569 to override this default) filenames differing only in case, or filenames
570 containing characters not valid on Windows.
572 On Windows, wimlib now supports capturing and extracting long paths
573 (longer than the so-called MAX_PATH).
575 On Windows, `wimlib-imagex update' now acquires proper privileges when
576 running as an Administrator.
578 `wimlib-imagex update' will now complain if no image is specified when
579 trying to update a multi-image WIM.
581 `wimlib-imagex update' now supports specifying a single update command
582 directly on the command line using the --command option.
584 wimlib-imagex will now choose different units for progress messages,
585 depending on the amount of data that needs to be processed.
587 `wimlib-imagex append' will now generate a unique WIM image name if no
588 name is specified and the defaulted name already exists in the WIM.
590 wimlib now allows you to create unnamed WIM images, which can then only
591 be referred to by index.
593 wimlib now allows you to explicitly declare you want write access to a
594 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
597 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
600 Progress callbacks have been added to wimlib's wimlib_update_image()
603 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
604 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
607 NTFS-3g capture now only warns about two conditions previously treated
610 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
613 wimlib now correctly detects and returns an error when reading a WIM
614 image with a cyclic directory structure. (Fun fact: such a WIM will
615 crash Microsoft's software.)
618 Added new "extract" and "update" subcommands to wimlib-imagex, along
619 with associated APIs in the library. These commands are intended mainly
620 for Windows use but can be used on UNIX as well.
622 Many documentation improvements.
624 Fixed a bug in the Windows build where relative symbolic links were not
625 captured in reparse-point fixup mode.
627 Fixed a bug in the Windows build where file handles were left open to
628 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
630 Fixed a bug in the Windows build of wimlib-imagex where globbing
631 split-WIM parts could cause the program to crash.
633 Fixed a bug where the creation time of WIM images would be shown instead
634 of the last modification time.
636 With the Windows build it is now possible to restore a WIM containing
637 symbolic links as a non-Administrator; however you will receive warnings
638 about not being able to extract the symbolic links.
641 Capturing a WIM image should now be significantly faster in most cases
642 due to improved use of the operating system's cache and avoiding reading
643 files twice whenever possible.
645 The Windows build should now work on Windows XP.
647 The Windows build now supports capturing and restoring hidden,
648 compressed, sparse, and encrypted files.
650 The Windows build now supports capturing and applying WIM images from
651 filesystems other than NTFS (with some reduced functionality).
653 The Windows build now extracts short names correctly.
655 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
656 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
657 capture' and `wimlib-imagex apply'.
659 The performance of splitting and joining WIMs should be slightly
662 The LZX and XPRESS compression and decompression functions are now
663 exported from the library.
666 Improvements and bugfixes for the Windows build.
668 Added --strict-acls options.
670 Fixed the way that wimlib determines the order of images in the WIM.
673 Since wimlib can now be used on Windows, wimlib's implementation of
674 ImageX has been renamed to wimlib-imagex to avoid confusion with
675 Microsoft's implementation of ImageX, which would have the same file
676 name ("imagex.exe"). If you really don't like this you can pass the
677 --with-imagex-progname option to `configure' to choose a different name,
678 or even simply rename the binary yourself (but the former way will
679 configure the man pages to use the chosen name).
681 Various bugs fixed in the Windows build. Mainly to do with capturing
682 and restoring alternate data streams correctly in weird cases, and
683 requesting the correct privileges when opening files. Also added the
684 --noacls options to wimlib-imagex capture, append, and apply.
686 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
687 dynamically loaded, so this may make the library compatible with Windows
688 XP (however, there may still be other problems).
691 Added experimental support for native Windows builds. Binaries can be
692 downloaded from the SourceForge page.
694 --source-list option added to `imagex capture' and `imagex append'.
696 Better support for different character encodings.
699 Storing UNIX file owners, groups, and modes in WIM images is now
700 possible using `imagex capture' with the --unix-data flag.
702 Minor bug fixes and documentation fixes.
705 NTFS capture: Fixed capturing duplicate reparse points.
707 NTFS capture: Capture first unnamed stream if there are more than one
708 (print warning instead of error).
710 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
713 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
716 Update to work with ntfs-3g version 2013.1.13.
719 Fixed truncating file to shorter but non-zero length on read-write
722 Various code cleanups and minor documentation fixes.
725 LZX and XPRESS decompression have received some additional optimizations
726 and should now be even faster. (Although, they were already pretty
727 fast--- much faster than typical I/O speeds.)
729 Fixed a bug introduced in v1.2.1 that would cause a directory tree
730 containing hard links to be captured incorrectly in some cases.
733 By default, unmounting a read-write mounted WIM with 'imagex unmount
734 --commit' will now change the WIM in-place without needing to write the
735 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
738 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
739 for a response from the daemon servicing the mounted WIM. Instead,
740 every second 'imagex unmount' will check if the daemon is still alive,
741 and keep waiting if so, otherwise terminate with an error.
743 'imagex unmount --commit' on a read-write mounted WIM will now print
744 progress information regarding the writing of new or modified streams
745 the WIM, just like when capturing or appending a WIM.
747 A small change has been made to XPRESS compression and it should improve
748 the compression ratio slightly.
750 A change was made that may improve performance slightly when applying a
751 WIM image to a NTFS volume.
753 Microsoft has managed to introduce even more bugs into their software,
754 and now the WIMs for Windows 8 have incorrect (too low) reference counts
755 for some streams. This is unsafe because such streams can be removed
756 when they are in actuality still referenced in the WIM (perhaps by a
757 different image). wimlib will now work around this problem by fixing
758 the stream reference counts. This is only done when wimlib_delete_image() is
759 called ('imagex delete') or when wimlib_mount_image() is called with
760 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
761 requires reading the metadata for all images in the WIM, so this will
762 make these operations noticably slower on WIMs with multiple images.
764 Various other bugfixes.
767 Appending images to a WIM is now be done by default without re-building
768 the whole WIM. Use the --rebuild flag to get the old behavior (which
769 was to re-build the entire WIM when a new image is appended).
771 A new command `imagex optimize' is now available to manually re-build a
772 WIM that has wasted space due to repeated appends.
774 Progress information has been improved, and now arbitrary callback
775 functions can be used to show the progress of a WIM operation.
777 A possible bug with changing the bootable image of a WIM was fixed.
779 Some advisory locking is now done to prevent two processes from
780 modifying a WIM at the same time (but only in some cases). For example,
781 you cannot mount two images from a WIM read-write at the same time.
783 Some functions have been reorganized:
784 * wimlib_mount() renamed to wimlib_mount_image().
785 * wimlib_unmount() renamed to wimlib_unmount_image().
786 * wimlib_overwrite_xml_and_header() removed as
787 wimlib_overwrite() suffices now.
788 * wimlib_apply_image_to_ntfs_volume() removed as
789 wimlib_extract_image() suffices now.
790 * wimlib_add_image_from_ntfs_volume() removed as
791 * wimlib_add_image() suffices now.
793 Previously, the soname of libwim.so has been 0.0.0, despite many
794 interface changes. The soname is now updated to 1.0.0 and will now be
795 updated each release.
798 Resources will now be compressed using multiple threads by default.
799 (This applies to `imagex capture', `imagex append', and `imagex
802 Some performance improvements in mounted WIMs.
804 More progress information is shown when capturing a WIM.
807 Lots of minor fixes, code cleanups, and some documentation updates.
808 Nothing in particular is really noteworthy.
811 LZX and XPRESS compression improvements.
813 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
814 Link Bytes of the WIM.
817 Fixed bug when capturing NTFS file with multiple named data streams.
819 Internally, we are now using inode structures, even though these don't
820 appear literally in the WIM file. This simplifies some of the code
821 (mainly for WIM mounting) and likely fixed a few problems, although it
825 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
829 Enough changes to call it version 1.0.0!
831 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
832 to a NTFS volume, is now supported.
834 Hard links and symbolic links have much improved support. They are
835 supported for WIM capture, WIM application, and mounted WIMs (you can
836 even make them on read-write mounted WIMs).
838 Alternate data streams are now supported on mounted WIMs through an
839 xattr or a Windows-style stream interface. Also they are supported when
840 capturing a WIM from NTFS or applying a WIM to NTFS.
842 Split WIMs are better supported. You may now apply an image directly
843 from a split WIM, mount an image from a split WIM read-only, or export
844 an image from a split WIM.
846 Using a capture configuration file is now supported (but not fully yet).
848 SHA1 message digests are checked in more places, so we can make sure
849 applied and captured data is correct.
851 Man pages have been updated and consolidated.
854 Fixed segfault when unmounting read-only WIM.
857 Support for joining and splitting WIMs.
858 Also, security data is now preserved by default.
861 Can now build with older gcc and system headers, like on CentOS 5.
864 Fixed bug that made it impossible to overwrite files in read-write
868 Write byte-order mark before WIM XML data. (imagex.exe requires this to
