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 Several improvements to System Compression (compact mode) support:
9 wof.sys (or wofadk.sys) is now automatically attached to the
10 target volume if needed.
12 Compact-mode extractions now work correctly with wofadk.sys on
13 older versions of Windows.
15 For compatibility with the Windows bootloader, XPRESS4K
16 compression is now automatically forced on certain files.
19 This release primarily contains various minor bug fixes and
20 improvements, including:
22 Improved handling of deep directory structures.
24 Fixed a bug where on 32-bit systems, the library could enter an
25 infinite loop if a WIM file was malformed in a specific way.
27 Added a workaround for a case where libntfs-3g may report
28 duplicate streams in an NTFS file.
30 Windows symbolic links and junctions in mounted WIM images are
31 now automatically rewritten to be valid in the mounted location.
33 Reparse point fixes: correctly handle the "ReparseReserved"
34 field, and correctly handle "empty" (data-less) reparse points.
36 On Windows, wimlib now acquires SeManageVolumePrivilege, which
37 is needed to create externally backed files using the
40 Improved validation of filenames.
42 Improved LZMS decompression speed.
44 The configure script now honors alternate pkg-config settings.
46 Links have been updated to point to the new website.
48 In addition, experimental support has been added for compressing
49 extracted files using System Compression on Windows 10. This
50 functionality is available through the new '--compact' option to
51 'wimapply' and 'wimextract' as well as new library flags.
54 Fixed a bug in the LZX decompressor: malicious input data could cause
55 out of bounds writes to memory (since wimlib v1.2.2).
57 The output of the 'wiminfo' command now consolidates various boolean
58 flags (such as "Relative path junction") into a single line.
60 A file can now have both an unnamed data stream ("file contents") and a
61 reparse point stream. Such files can exist as a result of the use of
62 certain Windows features, such as offline storage, including "OneDrive".
63 wimlib will now store and restore both streams on Windows as well as in
64 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
66 On Windows, named data streams of encrypted files are no longer stored
67 twice in WIM archives.
69 On Windows, named data streams are now correctly extracted to existing
70 "readonly" directories. Before, an error would be reported.
72 On Windows, it is now possible to do a "WIMBoot mode" extraction with
73 non-standalone WIMs such as delta WIMs.
75 On Windows, when doing an extraction in "WIMBoot mode", files larger
76 than 4 gigabytes are now never extracted as externally backed. This
77 works around a bug in Microsoft's "WOF" driver.
79 The '--enable-verify-compression' configure option has been removed. If
80 you want to verify a WIM file, use the 'wimverify' program.
82 The way the "file count", "directory count", "total bytes", and "hard
83 link bytes" image statistics (stored in the WIM XML data) is calculated
84 has been slightly changed.
86 In mounted WIM images, the disk usage provided for each file (st_blocks)
87 is now the compressed size rather than the uncompressed size.
89 The performance of the NTFS-3g and Windows capture modes has been
92 On UNIX-like systems, symbolic links whose targets contain the backslash
93 character are now handled correctly (losslessly).
96 Improved the LZX compressor. It is now 15-20% faster than before and
97 provides a slightly better compression ratio.
99 Improved the LZMS compressor. It now provides a compression ratio
100 slightly better than WIMGAPI while still being faster and using slightly
103 The compression chunk size in solid resources, e.g. when capturing or
104 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
105 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
106 better compression ratio and is the same value that WIMGAPI uses. The
107 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
108 lower than WIMGAPI's memory usage, but if it is too much, it is still
109 possible to choose a lower value, e.g. with the '--solid-chunk-size'
110 option to wimlib-imagex.
112 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
113 accept the 'K', 'M', and 'G' suffixes.
115 Files are now sorted by name extension when creating a solid WIM file.
117 Fixed various issues related to capture/apply of EFS-encrypted files on
120 The file list printed by 'wimdir' is now sorted by the platform-specific
121 case sensitivity setting, rather than always case sensitively. This
122 also affects the library function wimlib_iterate_dir_tree().
124 On Windows, some error and warning messages have been improved.
127 The Windows binary distribution no longer contains third party DLLs.
128 These dependencies are instead compiled directly into the libwim DLL.
130 Added more fixes for wimlib on non-x86 architectures such as ARM.
132 Extracting files to a Windows PE in-memory filesystem no longer fails if
133 the target files do not yet exist.
135 Improved the performance of XPRESS compression and LZMS decompression.
137 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
138 It will automatically be faster on newer Intel and AMD processors.
140 Removed the --with-imagex-progname and --enable-more-assertions
144 Fix for very slow export from solid WIM / ESD files.
146 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
148 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
149 may use this to treat some types of errors as non-fatal.
151 The library now permits making in-memory changes to a WIMStruct backed
152 by a read-only WIM file.
154 Fixes for "WIMBoot" extraction mode (Windows only):
156 When not using the WOF driver, extraction no longer fails if the
157 disk containing the WIM file has too many partitions.
159 When matching patterns in [PrepopulateList], all hard links of
160 each file are now considered.
162 The system registry files are now automatically treated as being
163 in [PrepopulateList].
165 Added a hack to try to work around an intermittent bug in
166 Microsoft's WOF (Windows Overlay Filesystem) driver.
169 Made more improvements to the XPRESS, LZX, and LZMS compressors.
171 A number of improvements to the Windows port:
173 Fixes for setting short filenames.
175 Faster "WIMBoot" extraction.
177 Updated and slimmed down the dependent DLLs.
179 ACL inheritence bits are now restored.
181 Mandatory integrity labels are now backed up and restored.
183 Added a workaround for an issue where in rare cases, wimlib could create
184 a compressed data stream that could not be read correctly by Windows
185 after an extraction in "WIMBoot" mode.
188 Added file count progress data for
189 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
190 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
192 Added support for testing file exclusions via the user-provided
195 Some documentation improvements.
197 Made some clarifications to the license text in the COPYING file.
200 Made more improvements to the XPRESS, LZX, and LZMS compressors.
202 The default compression mode for wimcapture is now LZX compression in
203 its default mode, which is the same as '--compress=maximum'.
205 You can now specify an optional integer compression level to the
206 '--compress' option; e.g. '--compress=lzx:75'.
208 Made a minor change to the LZMS compressor and decompressor to fix an
209 incompatibility with the Microsoft implementation. In the unlikely
210 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
211 earlier and a checksum error is reported when extracting files from it
212 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
215 Added 'verify' subcommand to wimlib-imagex.
217 Notable library changes:
219 Custom compressor parameters have been removed from the library
220 in favor of the simpler level-based API.
222 Decompressor parameters have been removed entirely.
224 Library users can now specify a custom file for warning and
225 error messages to be sent to, rather than the default of
228 New progress messages:
229 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
230 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
232 New function: wimlib_verify_wim().
235 Improved compression, decompression, and extraction performance.
237 Improved compatibility with version 3584 WIM / ESD files:
238 - Add support for reading and writing multiple solid blocks per
239 archive, which WIMGAPI/DISM can create when appending an image.
240 - Correctly create solid blocks larger than 4 GiB.
242 'add' commands passed to wimupdate will now replace existing
243 nondirectory files by default. Use the --no-replace option to get the
246 The license for the library now contains an exception that allows using
247 it under the LGPL. See the COPYING file for details.
249 In reparse-point fixup mode (the default for capture), symbolic links
250 and junctions that point outside the tree being captured are no longer
251 excluded from capture.
253 Added support for "WIMBoot" capture and extraction. See the
254 documentation for the new '--wimboot' option to wimcapture and wimapply
255 for more information.
257 On UNIX-like systems, you can now backup and restore device nodes, named
258 pipes, and sockets. In addition, 32-bit user and group IDs are now
261 The way that UNIX data is stored in WIM files has been changed. If you
262 captured any WIMs with the --unix-data option, to upgrade them you'll
263 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
264 re-capture them with --unix-data using this version.
266 wimlib now understands tagged metadata items, such as object IDs, that
267 can be stored in WIM directory entries.
269 Removed the --hardlink and --symlink options to wimapply, since I don't
270 think they are too useful and they got in the way of improving the code.
272 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
274 The 'mkwinpeimg' script now supports writing the ISO image to standard
277 The <ARCH> element in WIM XML data is now exported correctly.
279 On Windows, sparse file attributes are no longer set on extracted files.
280 Oddly enough, this actually saves disk space in some cases.
282 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
283 supported. Mounting WIM images now always requires extended attribute
284 support. Use --without-fuse to disable support for mounting WIM images;
285 this will also disable the need for extended attribute support.
287 Configuring with --enable-ssse3-sha1 now works correctly.
289 The shared library version has been bumped up. The main
290 incompatibilities are:
292 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
293 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
296 - User-provided progress functions are now registered using a
297 separate function, wimlib_register_progress_function(). The
298 'progress_func' argument to many functions no longer exists.
300 - The return value from user-provided progress functions is now
303 - A context argument has been added to the prototype of
304 user-provided progress functions.
306 - 'struct wimlib_capture_config' has been removed. The library
307 now takes the path to the configuration file directly. This
308 affects wimlib_add_image(), wimlib_add_image_multisource(),
309 and wimlib_update_image(). However, a NULL value passed in
310 the argument retains the same meaning.
312 - Removed deprecated functions: some (de)compression functions,
313 wimlib_extract_files(), and wimlib_print_metadata().
315 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
316 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
317 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
319 - Removed some progress messages:
320 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
321 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
322 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
325 - Removed some error codes. Numbering stays the same.
327 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
328 WIMLIB_UNMOUNT_FLAG_FORCE.
330 - WIM paths passed to progress functions now have a leading
334 Case-insensitive comparisons of strings (e.g. filenames) containing
335 UTF-16 codepoints above 32767 are now done correctly.
337 Fixed build failure on Mac OS X.
339 wimunmount now provides the '--new-image' option to cause changes to a
340 read-write mounted image to be committed as a new image rather than as
341 an update of the mounted image. (The corresponding new library flag is
342 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
344 The LZMS ("recovery") compression chunk size, or "dictionary size", may
345 now be up to 1 GiB (1,073,741,824 bytes).
347 The performance of LZX ("maximum") and LZMS ("recovery") compression
348 with large chunk sizes has been slightly improved.
351 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
352 decompressed correctly.
354 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
355 occurred in an unlikely case, and due to validity checks it did not
356 affect successfully created archives.
358 Fixed a minor compatibility issue with the LZMS compressor and
359 decompressor. This is *not* the default compression type and was only
360 introduced in v1.6.0. In the unlikely event that you created an
361 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
362 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
365 Memory usage for LZMS and LZX compression has been decreased.
367 wimextract now allows wildcard characters in paths specified on the
368 command line. Also, the '--strict-wildcards' option has been removed
369 and replaced with the inverse option '--nullglob'. See the
370 documentation for wimextract for more details and changes.
372 The wimlib_extract_files() function is now considered deprecated in
373 favor of wimlib_extract_paths().
375 Fixed more permissions problems when extracting files on Windows.
377 A new '--no-attributes' option has been added to wimapply and
378 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
380 The default chunk size is now set correctly when changing the
381 compression type of a WIM, for example with 'wimoptimize'.
383 The '--metadata' option to wiminfo has been replaced with the
384 '--detailed' option to wimdir.
386 In relevant wimlib-imagex commands, '--solid' may now be used as an
387 alias for '--pack-streams'.
390 Support for extracting and updating the new version 3584 WIMs has been
391 added. These WIMs typically pack many streams ("files") together into a
392 single compressed resource, thereby saving space. This degrades the
393 performance of random access (such as that which occurs on a mounted
394 image), but optimizations have been implemented for extraction. These
395 new WIM files also typically use a new compression format (LZMS), which
396 is similar to LZMA and can offer a better compression ratio than LZX.
397 These new WIM files can be created using `wimcapture' with
398 the '--compress=lzms --pack-streams' options. Note: this new WIM format
399 is used by the Windows 8 web downloader, but important segments of the
400 raw '.esd' files are encrypted, so wimlib will not be able to extract
401 such files until they are first decrypted.
403 wimlib now supports extracting files and directories from a WIM image
404 based on a "listfile" that itself contains the list of paths to extract.
405 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
406 and for the library itself, the new APIs are wimlib_extract_pathlist()
407 and wimlib_extract_paths(). Path globs containing wildcard characters
410 For searching WIM files, wimlib now has configurable case sensitivity.
411 The default on Windows is still case-insensitive and the default on
412 UNIX-like systems is still case-sensitive, but this can be overridden
413 on either platform through flags to wimlib_global_init(). For
414 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
415 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
418 Support for compression chunk sizes greater than the default of 32768
419 bytes has been added. A larger chunk size typically results in a better
420 compression ratio. However, the MS implementation is seemingly not
421 compatible with all chunk sizes, especially for LZX compression, so the
422 defaults remain unchanged, with the exception of the new LZMS-compressed
423 WIMs, which use a larger chunk size by default.
425 The compression/decompression API exported by wimlib has been changed.
426 Now one set of functions handles all supported compression formats.
428 `wimcapture' and `wimappend' will now display the progress of scanning
429 the directory tree to capture, in addition to the progress of writing
430 data to the WIM. The '--verbose' option no longer does anything. The
431 library API change for this is the addition of several members to
432 `struct wimlib_progress_info_scan' available to progress callbacks.
434 `mkwinpeimg' now correctly handles the '--start-script' option when the
435 start script is not in the working directory.
437 Sequential extraction, previously requested by using
438 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
439 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
440 behavior (extract in file order).
443 The new LZX compressor added in v1.5.2 has been improved and is now
444 enabled by default, except when `wimcapture' or `wimappend' is run
445 *without* the '--compress' option, in which case the faster LZX
446 compressor is used (the same as before). This behavior is reasonably
447 consistent with ImageX which actually uses "fast" (XPRESS) compression
448 by default. In those cases, use '--compress=maximum' to explicitly
449 capture a WIM image using the new (slower but better) LZX compressor.
451 The '--compress-slow' option still exists to `wimlib-imagex optimize',
452 but its new behavior is to tweak the new LZX compressor even more to
453 produce an even better compression ratio at the cost of more time spent
456 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
457 which recompresses the WIM file using the specified compression TYPE.
458 The new library API function used for this is
459 wimlib_set_output_compression_type().
461 Added the wimlib_get_xml_data() function to allow library clients to
462 easily retrieve the raw XML data from a WIM file if needed.
464 Fixed a bug that could cause an error code to be incorrectly returned
465 when writing XML data containing a <WINDOWS> element.
467 Mounted WIM images will now correctly show the default file stream even
468 if appears in the alternate data stream entries of the corresponding WIM
472 Added a new experimental LZX compressor which can be enabled by passing
473 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
474 optimize'. (The latter is only applicable if the WIM is already
475 LZX-compressed and the '--recompress' option is also given.) The
476 experimental compressor is much slower but compresses the data slightly
477 more --- currently usually to within a fraction of a percent of the
478 results from WIMGAPI/ImageX.
480 A workaround has been added for compatibility with versions of WinPE
481 that interpret alternate data stream entries in the boot WIM
484 An alignment bug that caused a crash in the LZX decompressor on some
487 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
488 the WIM header when restoring the previous state of a WIM it failed to
491 Added a workaround to avoid an access denied error on Windows when
492 replacing a WIM file that another process has opened.
495 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
496 needed to be handled.
498 A bug in the interpretation of negative IMAGE indices in the
499 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
500 `wimlib-imagex append' has been fixed.
502 A workaround has been added to successfully apply security descriptors
503 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
504 2013.1.13 or earlier.
506 `wimlib-imagex capture' can now accept the '--delta-from' option
510 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
511 to standard output and applying images from standard input, but they are
512 not compatible with Microsoft's software and are not created by default.
513 See the documentation for --pipable flag of `wimlib-imagex capture' for
516 To better support incremental backups, added support for declaring an
517 image as a modified form of another image. See the documentation for
518 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
521 Added supported for "delta" WIMs. See the documentation for the
522 '--delta-from' option of `wimlib-imagex capture'.
524 The library support for managing split WIMs has been changed to support
525 other arrangements, such as delta WIMs, and be easier to use. This
526 change is visible in `wimlib-imagex', which also can now accept the
527 '--ref' option multiple times, and also now supports "delta" WIMs as
530 wimlib now preserves WIM integrity tables by default, even if
531 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
532 behavior of `wimlib-imagex' whenever the WIM being operated on contains
533 an integrity table and the '--check' option is not specified.
535 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
536 (when --compress is not specified). This provides the best compression
537 ratio by default, which is usually what is desired, at a cost of some
540 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
541 is the command as in `wimlib-imagex COMMAND'; for example, it can be
542 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
543 appropriate hard links are created in UNIX installations of
544 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
545 batch files that emulate this behavior are generated.
547 Security descriptors are now extracted correctly on Windows.
549 Fixed archiving DOS names in NTFS-3g capture mode.
551 The extraction code has been rewritten and it will now be easier to
552 support new features on all supported backends (currently Win32, UNIX,
553 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
554 now supported on all backends, not just UNIX.
556 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
557 than the WAIK itself.
559 wimlib_global_init() now, by default, attempts to acquire additional
560 privileges on Windows, so library clients need not do this.
562 This update bumps the shared library version number up to 9, since it is
563 not binary compatibible with previous releases.
566 Fixed bug in `wimlib-imagex export' that made it impossible to export an
567 image from a WIM that is readonly at the filesystem level.
569 Return error code rather than segfaulting when trying to list files from
570 a non-first part of a split WIM.
572 Joining a WIM will now preserve the RP_FIX and READONLY flags.
575 On Windows, paths given to wimlib-imagex are now treated case
578 Improved behavior regarding invalid filenames; in particular, on
579 Windows, wimlib-imagex will, when extracting, now omit (with an option
580 to override this default) filenames differing only in case, or filenames
581 containing characters not valid on Windows.
583 On Windows, wimlib now supports capturing and extracting long paths
584 (longer than the so-called MAX_PATH).
586 On Windows, `wimlib-imagex update' now acquires proper privileges when
587 running as an Administrator.
589 `wimlib-imagex update' will now complain if no image is specified when
590 trying to update a multi-image WIM.
592 `wimlib-imagex update' now supports specifying a single update command
593 directly on the command line using the --command option.
595 wimlib-imagex will now choose different units for progress messages,
596 depending on the amount of data that needs to be processed.
598 `wimlib-imagex append' will now generate a unique WIM image name if no
599 name is specified and the defaulted name already exists in the WIM.
601 wimlib now allows you to create unnamed WIM images, which can then only
602 be referred to by index.
604 wimlib now allows you to explicitly declare you want write access to a
605 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
608 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
611 Progress callbacks have been added to wimlib's wimlib_update_image()
614 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
615 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
618 NTFS-3g capture now only warns about two conditions previously treated
621 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
624 wimlib now correctly detects and returns an error when reading a WIM
625 image with a cyclic directory structure. (Fun fact: such a WIM will
626 crash Microsoft's software.)
629 Added new "extract" and "update" subcommands to wimlib-imagex, along
630 with associated APIs in the library. These commands are intended mainly
631 for Windows use but can be used on UNIX as well.
633 Many documentation improvements.
635 Fixed a bug in the Windows build where relative symbolic links were not
636 captured in reparse-point fixup mode.
638 Fixed a bug in the Windows build where file handles were left open to
639 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
641 Fixed a bug in the Windows build of wimlib-imagex where globbing
642 split-WIM parts could cause the program to crash.
644 Fixed a bug where the creation time of WIM images would be shown instead
645 of the last modification time.
647 With the Windows build it is now possible to restore a WIM containing
648 symbolic links as a non-Administrator; however you will receive warnings
649 about not being able to extract the symbolic links.
652 Capturing a WIM image should now be significantly faster in most cases
653 due to improved use of the operating system's cache and avoiding reading
654 files twice whenever possible.
656 The Windows build should now work on Windows XP.
658 The Windows build now supports capturing and restoring hidden,
659 compressed, sparse, and encrypted files.
661 The Windows build now supports capturing and applying WIM images from
662 filesystems other than NTFS (with some reduced functionality).
664 The Windows build now extracts short names correctly.
666 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
667 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
668 capture' and `wimlib-imagex apply'.
670 The performance of splitting and joining WIMs should be slightly
673 The LZX and XPRESS compression and decompression functions are now
674 exported from the library.
677 Improvements and bugfixes for the Windows build.
679 Added --strict-acls options.
681 Fixed the way that wimlib determines the order of images in the WIM.
684 Since wimlib can now be used on Windows, wimlib's implementation of
685 ImageX has been renamed to wimlib-imagex to avoid confusion with
686 Microsoft's implementation of ImageX, which would have the same file
687 name ("imagex.exe"). If you really don't like this you can pass the
688 --with-imagex-progname option to `configure' to choose a different name,
689 or even simply rename the binary yourself (but the former way will
690 configure the man pages to use the chosen name).
692 Various bugs fixed in the Windows build. Mainly to do with capturing
693 and restoring alternate data streams correctly in weird cases, and
694 requesting the correct privileges when opening files. Also added the
695 --noacls options to wimlib-imagex capture, append, and apply.
697 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
698 dynamically loaded, so this may make the library compatible with Windows
699 XP (however, there may still be other problems).
702 Added experimental support for native Windows builds. Binaries can be
703 downloaded from the SourceForge page.
705 --source-list option added to `imagex capture' and `imagex append'.
707 Better support for different character encodings.
710 Storing UNIX file owners, groups, and modes in WIM images is now
711 possible using `imagex capture' with the --unix-data flag.
713 Minor bug fixes and documentation fixes.
716 NTFS capture: Fixed capturing duplicate reparse points.
718 NTFS capture: Capture first unnamed stream if there are more than one
719 (print warning instead of error).
721 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
724 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
727 Update to work with ntfs-3g version 2013.1.13.
730 Fixed truncating file to shorter but non-zero length on read-write
733 Various code cleanups and minor documentation fixes.
736 LZX and XPRESS decompression have received some additional optimizations
737 and should now be even faster. (Although, they were already pretty
738 fast--- much faster than typical I/O speeds.)
740 Fixed a bug introduced in v1.2.1 that would cause a directory tree
741 containing hard links to be captured incorrectly in some cases.
744 By default, unmounting a read-write mounted WIM with 'imagex unmount
745 --commit' will now change the WIM in-place without needing to write the
746 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
749 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
750 for a response from the daemon servicing the mounted WIM. Instead,
751 every second 'imagex unmount' will check if the daemon is still alive,
752 and keep waiting if so, otherwise terminate with an error.
754 'imagex unmount --commit' on a read-write mounted WIM will now print
755 progress information regarding the writing of new or modified streams
756 the WIM, just like when capturing or appending a WIM.
758 A small change has been made to XPRESS compression and it should improve
759 the compression ratio slightly.
761 A change was made that may improve performance slightly when applying a
762 WIM image to a NTFS volume.
764 Microsoft has managed to introduce even more bugs into their software,
765 and now the WIMs for Windows 8 have incorrect (too low) reference counts
766 for some streams. This is unsafe because such streams can be removed
767 when they are in actuality still referenced in the WIM (perhaps by a
768 different image). wimlib will now work around this problem by fixing
769 the stream reference counts. This is only done when wimlib_delete_image() is
770 called ('imagex delete') or when wimlib_mount_image() is called with
771 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
772 requires reading the metadata for all images in the WIM, so this will
773 make these operations noticably slower on WIMs with multiple images.
775 Various other bugfixes.
778 Appending images to a WIM is now be done by default without re-building
779 the whole WIM. Use the --rebuild flag to get the old behavior (which
780 was to re-build the entire WIM when a new image is appended).
782 A new command `imagex optimize' is now available to manually re-build a
783 WIM that has wasted space due to repeated appends.
785 Progress information has been improved, and now arbitrary callback
786 functions can be used to show the progress of a WIM operation.
788 A possible bug with changing the bootable image of a WIM was fixed.
790 Some advisory locking is now done to prevent two processes from
791 modifying a WIM at the same time (but only in some cases). For example,
792 you cannot mount two images from a WIM read-write at the same time.
794 Some functions have been reorganized:
795 * wimlib_mount() renamed to wimlib_mount_image().
796 * wimlib_unmount() renamed to wimlib_unmount_image().
797 * wimlib_overwrite_xml_and_header() removed as
798 wimlib_overwrite() suffices now.
799 * wimlib_apply_image_to_ntfs_volume() removed as
800 wimlib_extract_image() suffices now.
801 * wimlib_add_image_from_ntfs_volume() removed as
802 * wimlib_add_image() suffices now.
804 Previously, the soname of libwim.so has been 0.0.0, despite many
805 interface changes. The soname is now updated to 1.0.0 and will now be
806 updated each release.
809 Resources will now be compressed using multiple threads by default.
810 (This applies to `imagex capture', `imagex append', and `imagex
813 Some performance improvements in mounted WIMs.
815 More progress information is shown when capturing a WIM.
818 Lots of minor fixes, code cleanups, and some documentation updates.
819 Nothing in particular is really noteworthy.
822 LZX and XPRESS compression improvements.
824 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
825 Link Bytes of the WIM.
828 Fixed bug when capturing NTFS file with multiple named data streams.
830 Internally, we are now using inode structures, even though these don't
831 appear literally in the WIM file. This simplifies some of the code
832 (mainly for WIM mounting) and likely fixed a few problems, although it
836 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
840 Enough changes to call it version 1.0.0!
842 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
843 to a NTFS volume, is now supported.
845 Hard links and symbolic links have much improved support. They are
846 supported for WIM capture, WIM application, and mounted WIMs (you can
847 even make them on read-write mounted WIMs).
849 Alternate data streams are now supported on mounted WIMs through an
850 xattr or a Windows-style stream interface. Also they are supported when
851 capturing a WIM from NTFS or applying a WIM to NTFS.
853 Split WIMs are better supported. You may now apply an image directly
854 from a split WIM, mount an image from a split WIM read-only, or export
855 an image from a split WIM.
857 Using a capture configuration file is now supported (but not fully yet).
859 SHA1 message digests are checked in more places, so we can make sure
860 applied and captured data is correct.
862 Man pages have been updated and consolidated.
865 Fixed segfault when unmounting read-only WIM.
868 Support for joining and splitting WIMs.
869 Also, security data is now preserved by default.
872 Can now build with older gcc and system headers, like on CentOS 5.
875 Fixed bug that made it impossible to overwrite files in read-write
879 Write byte-order mark before WIM XML data. (imagex.exe requires this to
