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.
7 Made some small improvements to the compression algorithms.
9 Improved handling of WIM XML data and added two new API functions:
10 wimlib_get_image_property() and wimlib_set_image_property().
12 Several improvements to System Compression (compact mode) support:
14 wof.sys (or wofadk.sys) is now automatically attached to the
15 target volume if needed.
17 Compact-mode extractions now work correctly with wofadk.sys on
18 older versions of Windows.
20 For compatibility with the Windows bootloader, the requested
21 compression format now is overridden on certain files.
24 This release primarily contains various minor bug fixes and
25 improvements, including:
27 Improved handling of deep directory structures.
29 Fixed a bug where on 32-bit systems, the library could enter an
30 infinite loop if a WIM file was malformed in a specific way.
32 Added a workaround for a case where libntfs-3g may report
33 duplicate streams in an NTFS file.
35 Windows symbolic links and junctions in mounted WIM images are
36 now automatically rewritten to be valid in the mounted location.
38 Reparse point fixes: correctly handle the "ReparseReserved"
39 field, and correctly handle "empty" (data-less) reparse points.
41 On Windows, wimlib now acquires SeManageVolumePrivilege, which
42 is needed to create externally backed files using the
45 Improved validation of filenames.
47 Improved LZMS decompression speed.
49 The configure script now honors alternate pkg-config settings.
51 Links have been updated to point to the new website.
53 In addition, experimental support has been added for compressing
54 extracted files using System Compression on Windows 10. This
55 functionality is available through the new '--compact' option to
56 'wimapply' and 'wimextract' as well as new library flags.
59 Fixed a bug in the LZX decompressor: malicious input data could cause
60 out of bounds writes to memory (since wimlib v1.2.2).
62 The output of the 'wiminfo' command now consolidates various boolean
63 flags (such as "Relative path junction") into a single line.
65 A file can now have both an unnamed data stream ("file contents") and a
66 reparse point stream. Such files can exist as a result of the use of
67 certain Windows features, such as offline storage, including "OneDrive".
68 wimlib will now store and restore both streams on Windows as well as in
69 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
71 On Windows, named data streams of encrypted files are no longer stored
72 twice in WIM archives.
74 On Windows, named data streams are now correctly extracted to existing
75 "readonly" directories. Before, an error would be reported.
77 On Windows, it is now possible to do a "WIMBoot mode" extraction with
78 non-standalone WIMs such as delta WIMs.
80 On Windows, when doing an extraction in "WIMBoot mode", files larger
81 than 4 gigabytes are now never extracted as externally backed. This
82 works around a bug in Microsoft's "WOF" driver.
84 The '--enable-verify-compression' configure option has been removed. If
85 you want to verify a WIM file, use the 'wimverify' program.
87 The way the "file count", "directory count", "total bytes", and "hard
88 link bytes" image statistics (stored in the WIM XML data) is calculated
89 has been slightly changed.
91 In mounted WIM images, the disk usage provided for each file (st_blocks)
92 is now the compressed size rather than the uncompressed size.
94 The performance of the NTFS-3g and Windows capture modes has been
97 On UNIX-like systems, symbolic links whose targets contain the backslash
98 character are now handled correctly (losslessly).
101 Improved the LZX compressor. It is now 15-20% faster than before and
102 provides a slightly better compression ratio.
104 Improved the LZMS compressor. It now provides a compression ratio
105 slightly better than WIMGAPI while still being faster and using slightly
108 The compression chunk size in solid resources, e.g. when capturing or
109 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
110 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
111 better compression ratio and is the same value that WIMGAPI uses. The
112 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
113 lower than WIMGAPI's memory usage, but if it is too much, it is still
114 possible to choose a lower value, e.g. with the '--solid-chunk-size'
115 option to wimlib-imagex.
117 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
118 accept the 'K', 'M', and 'G' suffixes.
120 Files are now sorted by name extension when creating a solid WIM file.
122 Fixed various issues related to capture/apply of EFS-encrypted files on
125 The file list printed by 'wimdir' is now sorted by the platform-specific
126 case sensitivity setting, rather than always case sensitively. This
127 also affects the library function wimlib_iterate_dir_tree().
129 On Windows, some error and warning messages have been improved.
132 The Windows binary distribution no longer contains third party DLLs.
133 These dependencies are instead compiled directly into the libwim DLL.
135 Added more fixes for wimlib on non-x86 architectures such as ARM.
137 Extracting files to a Windows PE in-memory filesystem no longer fails if
138 the target files do not yet exist.
140 Improved the performance of XPRESS compression and LZMS decompression.
142 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
143 It will automatically be faster on newer Intel and AMD processors.
145 Removed the --with-imagex-progname and --enable-more-assertions
149 Fix for very slow export from solid WIM / ESD files.
151 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
153 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
154 may use this to treat some types of errors as non-fatal.
156 The library now permits making in-memory changes to a WIMStruct backed
157 by a read-only WIM file.
159 Fixes for "WIMBoot" extraction mode (Windows only):
161 When not using the WOF driver, extraction no longer fails if the
162 disk containing the WIM file has too many partitions.
164 When matching patterns in [PrepopulateList], all hard links of
165 each file are now considered.
167 The system registry files are now automatically treated as being
168 in [PrepopulateList].
170 Added a hack to try to work around an intermittent bug in
171 Microsoft's WOF (Windows Overlay Filesystem) driver.
174 Made more improvements to the XPRESS, LZX, and LZMS compressors.
176 A number of improvements to the Windows port:
178 Fixes for setting short filenames.
180 Faster "WIMBoot" extraction.
182 Updated and slimmed down the dependent DLLs.
184 ACL inheritence bits are now restored.
186 Mandatory integrity labels are now backed up and restored.
188 Added a workaround for an issue where in rare cases, wimlib could create
189 a compressed data stream that could not be read correctly by Windows
190 after an extraction in "WIMBoot" mode.
193 Added file count progress data for
194 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
195 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
197 Added support for testing file exclusions via the user-provided
200 Some documentation improvements.
202 Made some clarifications to the license text in the COPYING file.
205 Made more improvements to the XPRESS, LZX, and LZMS compressors.
207 The default compression mode for wimcapture is now LZX compression in
208 its default mode, which is the same as '--compress=maximum'.
210 You can now specify an optional integer compression level to the
211 '--compress' option; e.g. '--compress=lzx:75'.
213 Made a minor change to the LZMS compressor and decompressor to fix an
214 incompatibility with the Microsoft implementation. In the unlikely
215 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
216 earlier and a checksum error is reported when extracting files from it
217 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
220 Added 'verify' subcommand to wimlib-imagex.
222 Notable library changes:
224 Custom compressor parameters have been removed from the library
225 in favor of the simpler level-based API.
227 Decompressor parameters have been removed entirely.
229 Library users can now specify a custom file for warning and
230 error messages to be sent to, rather than the default of
233 New progress messages:
234 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
235 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
237 New function: wimlib_verify_wim().
240 Improved compression, decompression, and extraction performance.
242 Improved compatibility with version 3584 WIM / ESD files:
243 - Add support for reading and writing multiple solid blocks per
244 archive, which WIMGAPI/DISM can create when appending an image.
245 - Correctly create solid blocks larger than 4 GiB.
247 'add' commands passed to wimupdate will now replace existing
248 nondirectory files by default. Use the --no-replace option to get the
251 The license for the library now contains an exception that allows using
252 it under the LGPL. See the COPYING file for details.
254 In reparse-point fixup mode (the default for capture), symbolic links
255 and junctions that point outside the tree being captured are no longer
256 excluded from capture.
258 Added support for "WIMBoot" capture and extraction. See the
259 documentation for the new '--wimboot' option to wimcapture and wimapply
260 for more information.
262 On UNIX-like systems, you can now backup and restore device nodes, named
263 pipes, and sockets. In addition, 32-bit user and group IDs are now
266 The way that UNIX data is stored in WIM files has been changed. If you
267 captured any WIMs with the --unix-data option, to upgrade them you'll
268 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
269 re-capture them with --unix-data using this version.
271 wimlib now understands tagged metadata items, such as object IDs, that
272 can be stored in WIM directory entries.
274 Removed the --hardlink and --symlink options to wimapply, since I don't
275 think they are too useful and they got in the way of improving the code.
277 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
279 The 'mkwinpeimg' script now supports writing the ISO image to standard
282 The <ARCH> element in WIM XML data is now exported correctly.
284 On Windows, sparse file attributes are no longer set on extracted files.
285 Oddly enough, this actually saves disk space in some cases.
287 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
288 supported. Mounting WIM images now always requires extended attribute
289 support. Use --without-fuse to disable support for mounting WIM images;
290 this will also disable the need for extended attribute support.
292 Configuring with --enable-ssse3-sha1 now works correctly.
294 The shared library version has been bumped up. The main
295 incompatibilities are:
297 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
298 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
301 - User-provided progress functions are now registered using a
302 separate function, wimlib_register_progress_function(). The
303 'progress_func' argument to many functions no longer exists.
305 - The return value from user-provided progress functions is now
308 - A context argument has been added to the prototype of
309 user-provided progress functions.
311 - 'struct wimlib_capture_config' has been removed. The library
312 now takes the path to the configuration file directly. This
313 affects wimlib_add_image(), wimlib_add_image_multisource(),
314 and wimlib_update_image(). However, a NULL value passed in
315 the argument retains the same meaning.
317 - Removed deprecated functions: some (de)compression functions,
318 wimlib_extract_files(), and wimlib_print_metadata().
320 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
321 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
322 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
324 - Removed some progress messages:
325 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
326 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
327 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
330 - Removed some error codes. Numbering stays the same.
332 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
333 WIMLIB_UNMOUNT_FLAG_FORCE.
335 - WIM paths passed to progress functions now have a leading
339 Case-insensitive comparisons of strings (e.g. filenames) containing
340 UTF-16 codepoints above 32767 are now done correctly.
342 Fixed build failure on Mac OS X.
344 wimunmount now provides the '--new-image' option to cause changes to a
345 read-write mounted image to be committed as a new image rather than as
346 an update of the mounted image. (The corresponding new library flag is
347 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
349 The LZMS ("recovery") compression chunk size, or "dictionary size", may
350 now be up to 1 GiB (1,073,741,824 bytes).
352 The performance of LZX ("maximum") and LZMS ("recovery") compression
353 with large chunk sizes has been slightly improved.
356 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
357 decompressed correctly.
359 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
360 occurred in an unlikely case, and due to validity checks it did not
361 affect successfully created archives.
363 Fixed a minor compatibility issue with the LZMS compressor and
364 decompressor. This is *not* the default compression type and was only
365 introduced in v1.6.0. In the unlikely event that you created an
366 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
367 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
370 Memory usage for LZMS and LZX compression has been decreased.
372 wimextract now allows wildcard characters in paths specified on the
373 command line. Also, the '--strict-wildcards' option has been removed
374 and replaced with the inverse option '--nullglob'. See the
375 documentation for wimextract for more details and changes.
377 The wimlib_extract_files() function is now considered deprecated in
378 favor of wimlib_extract_paths().
380 Fixed more permissions problems when extracting files on Windows.
382 A new '--no-attributes' option has been added to wimapply and
383 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
385 The default chunk size is now set correctly when changing the
386 compression type of a WIM, for example with 'wimoptimize'.
388 The '--metadata' option to wiminfo has been replaced with the
389 '--detailed' option to wimdir.
391 In relevant wimlib-imagex commands, '--solid' may now be used as an
392 alias for '--pack-streams'.
395 Support for extracting and updating the new version 3584 WIMs has been
396 added. These WIMs typically pack many streams ("files") together into a
397 single compressed resource, thereby saving space. This degrades the
398 performance of random access (such as that which occurs on a mounted
399 image), but optimizations have been implemented for extraction. These
400 new WIM files also typically use a new compression format (LZMS), which
401 is similar to LZMA and can offer a better compression ratio than LZX.
402 These new WIM files can be created using `wimcapture' with
403 the '--compress=lzms --pack-streams' options. Note: this new WIM format
404 is used by the Windows 8 web downloader, but important segments of the
405 raw '.esd' files are encrypted, so wimlib will not be able to extract
406 such files until they are first decrypted.
408 wimlib now supports extracting files and directories from a WIM image
409 based on a "listfile" that itself contains the list of paths to extract.
410 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
411 and for the library itself, the new APIs are wimlib_extract_pathlist()
412 and wimlib_extract_paths(). Path globs containing wildcard characters
415 For searching WIM files, wimlib now has configurable case sensitivity.
416 The default on Windows is still case-insensitive and the default on
417 UNIX-like systems is still case-sensitive, but this can be overridden
418 on either platform through flags to wimlib_global_init(). For
419 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
420 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
423 Support for compression chunk sizes greater than the default of 32768
424 bytes has been added. A larger chunk size typically results in a better
425 compression ratio. However, the MS implementation is seemingly not
426 compatible with all chunk sizes, especially for LZX compression, so the
427 defaults remain unchanged, with the exception of the new LZMS-compressed
428 WIMs, which use a larger chunk size by default.
430 The compression/decompression API exported by wimlib has been changed.
431 Now one set of functions handles all supported compression formats.
433 `wimcapture' and `wimappend' will now display the progress of scanning
434 the directory tree to capture, in addition to the progress of writing
435 data to the WIM. The '--verbose' option no longer does anything. The
436 library API change for this is the addition of several members to
437 `struct wimlib_progress_info_scan' available to progress callbacks.
439 `mkwinpeimg' now correctly handles the '--start-script' option when the
440 start script is not in the working directory.
442 Sequential extraction, previously requested by using
443 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
444 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
445 behavior (extract in file order).
448 The new LZX compressor added in v1.5.2 has been improved and is now
449 enabled by default, except when `wimcapture' or `wimappend' is run
450 *without* the '--compress' option, in which case the faster LZX
451 compressor is used (the same as before). This behavior is reasonably
452 consistent with ImageX which actually uses "fast" (XPRESS) compression
453 by default. In those cases, use '--compress=maximum' to explicitly
454 capture a WIM image using the new (slower but better) LZX compressor.
456 The '--compress-slow' option still exists to `wimlib-imagex optimize',
457 but its new behavior is to tweak the new LZX compressor even more to
458 produce an even better compression ratio at the cost of more time spent
461 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
462 which recompresses the WIM file using the specified compression TYPE.
463 The new library API function used for this is
464 wimlib_set_output_compression_type().
466 Added the wimlib_get_xml_data() function to allow library clients to
467 easily retrieve the raw XML data from a WIM file if needed.
469 Fixed a bug that could cause an error code to be incorrectly returned
470 when writing XML data containing a <WINDOWS> element.
472 Mounted WIM images will now correctly show the default file stream even
473 if appears in the alternate data stream entries of the corresponding WIM
477 Added a new experimental LZX compressor which can be enabled by passing
478 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
479 optimize'. (The latter is only applicable if the WIM is already
480 LZX-compressed and the '--recompress' option is also given.) The
481 experimental compressor is much slower but compresses the data slightly
482 more --- currently usually to within a fraction of a percent of the
483 results from WIMGAPI/ImageX.
485 A workaround has been added for compatibility with versions of WinPE
486 that interpret alternate data stream entries in the boot WIM
489 An alignment bug that caused a crash in the LZX decompressor on some
492 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
493 the WIM header when restoring the previous state of a WIM it failed to
496 Added a workaround to avoid an access denied error on Windows when
497 replacing a WIM file that another process has opened.
500 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
501 needed to be handled.
503 A bug in the interpretation of negative IMAGE indices in the
504 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
505 `wimlib-imagex append' has been fixed.
507 A workaround has been added to successfully apply security descriptors
508 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
509 2013.1.13 or earlier.
511 `wimlib-imagex capture' can now accept the '--delta-from' option
515 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
516 to standard output and applying images from standard input, but they are
517 not compatible with Microsoft's software and are not created by default.
518 See the documentation for --pipable flag of `wimlib-imagex capture' for
521 To better support incremental backups, added support for declaring an
522 image as a modified form of another image. See the documentation for
523 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
526 Added supported for "delta" WIMs. See the documentation for the
527 '--delta-from' option of `wimlib-imagex capture'.
529 The library support for managing split WIMs has been changed to support
530 other arrangements, such as delta WIMs, and be easier to use. This
531 change is visible in `wimlib-imagex', which also can now accept the
532 '--ref' option multiple times, and also now supports "delta" WIMs as
535 wimlib now preserves WIM integrity tables by default, even if
536 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
537 behavior of `wimlib-imagex' whenever the WIM being operated on contains
538 an integrity table and the '--check' option is not specified.
540 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
541 (when --compress is not specified). This provides the best compression
542 ratio by default, which is usually what is desired, at a cost of some
545 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
546 is the command as in `wimlib-imagex COMMAND'; for example, it can be
547 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
548 appropriate hard links are created in UNIX installations of
549 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
550 batch files that emulate this behavior are generated.
552 Security descriptors are now extracted correctly on Windows.
554 Fixed archiving DOS names in NTFS-3g capture mode.
556 The extraction code has been rewritten and it will now be easier to
557 support new features on all supported backends (currently Win32, UNIX,
558 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
559 now supported on all backends, not just UNIX.
561 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
562 than the WAIK itself.
564 wimlib_global_init() now, by default, attempts to acquire additional
565 privileges on Windows, so library clients need not do this.
567 This update bumps the shared library version number up to 9, since it is
568 not binary compatibible with previous releases.
571 Fixed bug in `wimlib-imagex export' that made it impossible to export an
572 image from a WIM that is readonly at the filesystem level.
574 Return error code rather than segfaulting when trying to list files from
575 a non-first part of a split WIM.
577 Joining a WIM will now preserve the RP_FIX and READONLY flags.
580 On Windows, paths given to wimlib-imagex are now treated case
583 Improved behavior regarding invalid filenames; in particular, on
584 Windows, wimlib-imagex will, when extracting, now omit (with an option
585 to override this default) filenames differing only in case, or filenames
586 containing characters not valid on Windows.
588 On Windows, wimlib now supports capturing and extracting long paths
589 (longer than the so-called MAX_PATH).
591 On Windows, `wimlib-imagex update' now acquires proper privileges when
592 running as an Administrator.
594 `wimlib-imagex update' will now complain if no image is specified when
595 trying to update a multi-image WIM.
597 `wimlib-imagex update' now supports specifying a single update command
598 directly on the command line using the --command option.
600 wimlib-imagex will now choose different units for progress messages,
601 depending on the amount of data that needs to be processed.
603 `wimlib-imagex append' will now generate a unique WIM image name if no
604 name is specified and the defaulted name already exists in the WIM.
606 wimlib now allows you to create unnamed WIM images, which can then only
607 be referred to by index.
609 wimlib now allows you to explicitly declare you want write access to a
610 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
613 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
616 Progress callbacks have been added to wimlib's wimlib_update_image()
619 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
620 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
623 NTFS-3g capture now only warns about two conditions previously treated
626 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
629 wimlib now correctly detects and returns an error when reading a WIM
630 image with a cyclic directory structure. (Fun fact: such a WIM will
631 crash Microsoft's software.)
634 Added new "extract" and "update" subcommands to wimlib-imagex, along
635 with associated APIs in the library. These commands are intended mainly
636 for Windows use but can be used on UNIX as well.
638 Many documentation improvements.
640 Fixed a bug in the Windows build where relative symbolic links were not
641 captured in reparse-point fixup mode.
643 Fixed a bug in the Windows build where file handles were left open to
644 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
646 Fixed a bug in the Windows build of wimlib-imagex where globbing
647 split-WIM parts could cause the program to crash.
649 Fixed a bug where the creation time of WIM images would be shown instead
650 of the last modification time.
652 With the Windows build it is now possible to restore a WIM containing
653 symbolic links as a non-Administrator; however you will receive warnings
654 about not being able to extract the symbolic links.
657 Capturing a WIM image should now be significantly faster in most cases
658 due to improved use of the operating system's cache and avoiding reading
659 files twice whenever possible.
661 The Windows build should now work on Windows XP.
663 The Windows build now supports capturing and restoring hidden,
664 compressed, sparse, and encrypted files.
666 The Windows build now supports capturing and applying WIM images from
667 filesystems other than NTFS (with some reduced functionality).
669 The Windows build now extracts short names correctly.
671 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
672 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
673 capture' and `wimlib-imagex apply'.
675 The performance of splitting and joining WIMs should be slightly
678 The LZX and XPRESS compression and decompression functions are now
679 exported from the library.
682 Improvements and bugfixes for the Windows build.
684 Added --strict-acls options.
686 Fixed the way that wimlib determines the order of images in the WIM.
689 Since wimlib can now be used on Windows, wimlib's implementation of
690 ImageX has been renamed to wimlib-imagex to avoid confusion with
691 Microsoft's implementation of ImageX, which would have the same file
692 name ("imagex.exe"). If you really don't like this you can pass the
693 --with-imagex-progname option to `configure' to choose a different name,
694 or even simply rename the binary yourself (but the former way will
695 configure the man pages to use the chosen name).
697 Various bugs fixed in the Windows build. Mainly to do with capturing
698 and restoring alternate data streams correctly in weird cases, and
699 requesting the correct privileges when opening files. Also added the
700 --noacls options to wimlib-imagex capture, append, and apply.
702 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
703 dynamically loaded, so this may make the library compatible with Windows
704 XP (however, there may still be other problems).
707 Added experimental support for native Windows builds. Binaries can be
708 downloaded from the SourceForge page.
710 --source-list option added to `imagex capture' and `imagex append'.
712 Better support for different character encodings.
715 Storing UNIX file owners, groups, and modes in WIM images is now
716 possible using `imagex capture' with the --unix-data flag.
718 Minor bug fixes and documentation fixes.
721 NTFS capture: Fixed capturing duplicate reparse points.
723 NTFS capture: Capture first unnamed stream if there are more than one
724 (print warning instead of error).
726 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
729 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
732 Update to work with ntfs-3g version 2013.1.13.
735 Fixed truncating file to shorter but non-zero length on read-write
738 Various code cleanups and minor documentation fixes.
741 LZX and XPRESS decompression have received some additional optimizations
742 and should now be even faster. (Although, they were already pretty
743 fast--- much faster than typical I/O speeds.)
745 Fixed a bug introduced in v1.2.1 that would cause a directory tree
746 containing hard links to be captured incorrectly in some cases.
749 By default, unmounting a read-write mounted WIM with 'imagex unmount
750 --commit' will now change the WIM in-place without needing to write the
751 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
754 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
755 for a response from the daemon servicing the mounted WIM. Instead,
756 every second 'imagex unmount' will check if the daemon is still alive,
757 and keep waiting if so, otherwise terminate with an error.
759 'imagex unmount --commit' on a read-write mounted WIM will now print
760 progress information regarding the writing of new or modified streams
761 the WIM, just like when capturing or appending a WIM.
763 A small change has been made to XPRESS compression and it should improve
764 the compression ratio slightly.
766 A change was made that may improve performance slightly when applying a
767 WIM image to a NTFS volume.
769 Microsoft has managed to introduce even more bugs into their software,
770 and now the WIMs for Windows 8 have incorrect (too low) reference counts
771 for some streams. This is unsafe because such streams can be removed
772 when they are in actuality still referenced in the WIM (perhaps by a
773 different image). wimlib will now work around this problem by fixing
774 the stream reference counts. This is only done when wimlib_delete_image() is
775 called ('imagex delete') or when wimlib_mount_image() is called with
776 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
777 requires reading the metadata for all images in the WIM, so this will
778 make these operations noticably slower on WIMs with multiple images.
780 Various other bugfixes.
783 Appending images to a WIM is now be done by default without re-building
784 the whole WIM. Use the --rebuild flag to get the old behavior (which
785 was to re-build the entire WIM when a new image is appended).
787 A new command `imagex optimize' is now available to manually re-build a
788 WIM that has wasted space due to repeated appends.
790 Progress information has been improved, and now arbitrary callback
791 functions can be used to show the progress of a WIM operation.
793 A possible bug with changing the bootable image of a WIM was fixed.
795 Some advisory locking is now done to prevent two processes from
796 modifying a WIM at the same time (but only in some cases). For example,
797 you cannot mount two images from a WIM read-write at the same time.
799 Some functions have been reorganized:
800 * wimlib_mount() renamed to wimlib_mount_image().
801 * wimlib_unmount() renamed to wimlib_unmount_image().
802 * wimlib_overwrite_xml_and_header() removed as
803 wimlib_overwrite() suffices now.
804 * wimlib_apply_image_to_ntfs_volume() removed as
805 wimlib_extract_image() suffices now.
806 * wimlib_add_image_from_ntfs_volume() removed as
807 * wimlib_add_image() suffices now.
809 Previously, the soname of libwim.so has been 0.0.0, despite many
810 interface changes. The soname is now updated to 1.0.0 and will now be
811 updated each release.
814 Resources will now be compressed using multiple threads by default.
815 (This applies to `imagex capture', `imagex append', and `imagex
818 Some performance improvements in mounted WIMs.
820 More progress information is shown when capturing a WIM.
823 Lots of minor fixes, code cleanups, and some documentation updates.
824 Nothing in particular is really noteworthy.
827 LZX and XPRESS compression improvements.
829 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
830 Link Bytes of the WIM.
833 Fixed bug when capturing NTFS file with multiple named data streams.
835 Internally, we are now using inode structures, even though these don't
836 appear literally in the WIM file. This simplifies some of the code
837 (mainly for WIM mounting) and likely fixed a few problems, although it
841 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
845 Enough changes to call it version 1.0.0!
847 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
848 to a NTFS volume, is now supported.
850 Hard links and symbolic links have much improved support. They are
851 supported for WIM capture, WIM application, and mounted WIMs (you can
852 even make them on read-write mounted WIMs).
854 Alternate data streams are now supported on mounted WIMs through an
855 xattr or a Windows-style stream interface. Also they are supported when
856 capturing a WIM from NTFS or applying a WIM to NTFS.
858 Split WIMs are better supported. You may now apply an image directly
859 from a split WIM, mount an image from a split WIM read-only, or export
860 an image from a split WIM.
862 Using a capture configuration file is now supported (but not fully yet).
864 SHA1 message digests are checked in more places, so we can make sure
865 applied and captured data is correct.
867 Man pages have been updated and consolidated.
870 Fixed segfault when unmounting read-only WIM.
873 Support for joining and splitting WIMs.
874 Also, security data is now preserved by default.
877 Can now build with older gcc and system headers, like on CentOS 5.
880 Fixed bug that made it impossible to overwrite files in read-write
884 Write byte-order mark before WIM XML data. (imagex.exe requires this to
