2 Fixed a bug: on 32-bit systems, the library would enter an infinite loop
3 if WIM image metadata was malformed in a very specific way.
5 Reduced the stack space used by directory tree scans.
7 Windows symbolic links and junctions in mounted WIM images are now
8 automatically rewritten to be valid in the mounted location.
11 Fixed a bug in the LZX decompressor: malicious input data could cause
12 out of bounds writes to memory (since wimlib v1.2.2).
14 The output of the 'wiminfo' command now consolidates various boolean
15 flags (such as "Relative path junction") into a single line.
17 A file can now have both an unnamed data stream ("file contents") and a
18 reparse point stream. Such files can exist as a result of the use of
19 certain Windows features, such as offline storage, including "OneDrive".
20 wimlib will now store and restore both streams on Windows as well as in
21 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
23 On Windows, named data streams of encrypted files are no longer stored
24 twice in WIM archives.
26 On Windows, named data streams are now correctly extracted to existing
27 "readonly" directories. Before, an error would be reported.
29 On Windows, it is now possible to do a "WIMBoot mode" extraction with
30 non-standalone WIMs such as delta WIMs.
32 On Windows, when doing an extraction in "WIMBoot mode", files larger
33 than 4 gigabytes are now never extracted as externally backed. This
34 works around a bug in Microsoft's "WOF" driver.
36 The '--enable-verify-compression' configure option has been removed. If
37 you want to verify a WIM file, use the 'wimverify' program.
39 The way the "file count", "directory count", "total bytes", and "hard
40 link bytes" image statistics (stored in the WIM XML data) is calculated
41 has been slightly changed.
43 In mounted WIM images, the disk usage provided for each file (st_blocks)
44 is now the compressed size rather than the uncompressed size.
46 The performance of the NTFS-3g and Windows capture modes has been
49 On UNIX-like systems, symbolic links whose targets contain the backslash
50 character are now handled correctly (losslessly).
53 Improved the LZX compressor. It is now 15-20% faster than before and
54 provides a slightly better compression ratio.
56 Improved the LZMS compressor. It now provides a compression ratio
57 slightly better than WIMGAPI while still being faster and using slightly
60 The compression chunk size in solid resources, e.g. when capturing or
61 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
62 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
63 better compression ratio and is the same value that WIMGAPI uses. The
64 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
65 lower than WIMGAPI's memory usage, but if it is too much, it is still
66 possible to choose a lower value, e.g. with the '--solid-chunk-size'
67 option to wimlib-imagex.
69 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
70 accept the 'K', 'M', and 'G' suffixes.
72 Files are now sorted by name extension when creating a solid WIM file.
74 Fixed various issues related to capture/apply of EFS-encrypted files on
77 The file list printed by 'wimdir' is now sorted by the platform-specific
78 case sensitivity setting, rather than always case sensitively. This
79 also affects the library function wimlib_iterate_dir_tree().
81 On Windows, some error and warning messages have been improved.
84 The Windows binary distribution no longer contains third party DLLs.
85 These dependencies are instead compiled directly into the libwim DLL.
87 Added more fixes for wimlib on non-x86 architectures such as ARM.
89 Extracting files to a Windows PE in-memory filesystem no longer fails if
90 the target files do not yet exist.
92 Improved the performance of XPRESS compression and LZMS decompression.
94 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
95 It will automatically be faster on newer Intel and AMD processors.
97 Removed the --with-imagex-progname and --enable-more-assertions
101 Fix for very slow export from solid WIM / ESD files.
103 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
105 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
106 may use this to treat some types of errors as non-fatal.
108 The library now permits making in-memory changes to a WIMStruct backed
109 by a read-only WIM file.
111 Fixes for "WIMBoot" extraction mode (Windows only):
113 When not using the WOF driver, extraction no longer fails if the
114 disk containing the WIM file has too many partitions.
116 When matching patterns in [PrepopulateList], all hard links of
117 each file are now considered.
119 The system registry files are now automatically treated as being
120 in [PrepopulateList].
122 Added a hack to try to work around an intermittent bug in
123 Microsoft's WOF (Windows Overlay Filesystem) driver.
126 Made more improvements to the XPRESS, LZX, and LZMS compressors.
128 A number of improvements to the Windows port:
130 Fixes for setting short filenames.
132 Faster "WIMBoot" extraction.
134 Updated and slimmed down the dependent DLLs.
136 ACL inheritence bits are now restored.
138 Mandatory integrity labels are now backed up and restored.
140 Added a workaround for an issue where in rare cases, wimlib could create
141 a compressed data stream that could not be read correctly by Windows
142 after an extraction in "WIMBoot" mode.
145 Added file count progress data for
146 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
147 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
149 Added support for testing file exclusions via the user-provided
152 Some documentation improvements.
154 Made some clarifications to the license text in the COPYING file.
157 Made more improvements to the XPRESS, LZX, and LZMS compressors.
159 The default compression mode for wimcapture is now LZX compression in
160 its default mode, which is the same as '--compress=maximum'.
162 You can now specify an optional integer compression level to the
163 '--compress' option; e.g. '--compress=lzx:75'.
165 Made a minor change to the LZMS compressor and decompressor to fix an
166 incompatibility with the Microsoft implementation. In the unlikely
167 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
168 earlier and a checksum error is reported when extracting files from it
169 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
172 Added 'verify' subcommand to wimlib-imagex.
174 Notable library changes:
176 Custom compressor parameters have been removed from the library
177 in favor of the simpler level-based API.
179 Decompressor parameters have been removed entirely.
181 Library users can now specify a custom file for warning and
182 error messages to be sent to, rather than the default of
185 New progress messages:
186 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
187 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
189 New function: wimlib_verify_wim().
192 Improved compression, decompression, and extraction performance.
194 Improved compatibility with version 3584 WIM / ESD files:
195 - Add support for reading and writing multiple solid blocks per
196 archive, which WIMGAPI/DISM can create when appending an image.
197 - Correctly create solid blocks larger than 4 GiB.
199 'add' commands passed to wimupdate will now replace existing
200 nondirectory files by default. Use the --no-replace option to get the
203 The license for the library now contains an exception that allows using
204 it under the LGPL. See the COPYING file for details.
206 In reparse-point fixup mode (the default for capture), symbolic links
207 and junctions that point outside the tree being captured are no longer
208 excluded from capture.
210 Added support for "WIMBoot" capture and extraction. See the
211 documentation for the new '--wimboot' option to wimcapture and wimapply
212 for more information.
214 On UNIX-like systems, you can now backup and restore device nodes, named
215 pipes, and sockets. In addition, 32-bit user and group IDs are now
218 The way that UNIX data is stored in WIM files has been changed. If you
219 captured any WIMs with the --unix-data option, to upgrade them you'll
220 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
221 re-capture them with --unix-data using this version.
223 wimlib now understands tagged metadata items, such as object IDs, that
224 can be stored in WIM directory entries.
226 Removed the --hardlink and --symlink options to wimapply, since I don't
227 think they are too useful and they got in the way of improving the code.
229 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
231 The 'mkwinpeimg' script now supports writing the ISO image to standard
234 The <ARCH> element in WIM XML data is now exported correctly.
236 On Windows, sparse file attributes are no longer set on extracted files.
237 Oddly enough, this actually saves disk space in some cases.
239 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
240 supported. Mounting WIM images now always requires extended attribute
241 support. Use --without-fuse to disable support for mounting WIM images;
242 this will also disable the need for extended attribute support.
244 Configuring with --enable-ssse3-sha1 now works correctly.
246 The shared library version has been bumped up. The main
247 incompatibilities are:
249 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
250 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
253 - User-provided progress functions are now registered using a
254 separate function, wimlib_register_progress_function(). The
255 'progress_func' argument to many functions no longer exists.
257 - The return value from user-provided progress functions is now
260 - A context argument has been added to the prototype of
261 user-provided progress functions.
263 - 'struct wimlib_capture_config' has been removed. The library
264 now takes the path to the configuration file directly. This
265 affects wimlib_add_image(), wimlib_add_image_multisource(),
266 and wimlib_update_image(). However, a NULL value passed in
267 the argument retains the same meaning.
269 - Removed deprecated functions: some (de)compression functions,
270 wimlib_extract_files(), and wimlib_print_metadata().
272 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
273 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
274 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
276 - Removed some progress messages:
277 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
278 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
279 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
282 - Removed some error codes. Numbering stays the same.
284 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
285 WIMLIB_UNMOUNT_FLAG_FORCE.
287 - WIM paths passed to progress functions now have a leading
291 Case-insensitive comparisons of strings (e.g. filenames) containing
292 UTF-16 codepoints above 32767 are now done correctly.
294 Fixed build failure on Mac OS X.
296 wimunmount now provides the '--new-image' option to cause changes to a
297 read-write mounted image to be committed as a new image rather than as
298 an update of the mounted image. (The corresponding new library flag is
299 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
301 The LZMS ("recovery") compression chunk size, or "dictionary size", may
302 now be up to 1 GiB (1,073,741,824 bytes).
304 The performance of LZX ("maximum") and LZMS ("recovery") compression
305 with large chunk sizes has been slightly improved.
308 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
309 decompressed correctly.
311 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
312 occurred in an unlikely case, and due to validity checks it did not
313 affect successfully created archives.
315 Fixed a minor compatibility issue with the LZMS compressor and
316 decompressor. This is *not* the default compression type and was only
317 introduced in v1.6.0. In the unlikely event that you created an
318 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
319 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
322 Memory usage for LZMS and LZX compression has been decreased.
324 wimextract now allows wildcard characters in paths specified on the
325 command line. Also, the '--strict-wildcards' option has been removed
326 and replaced with the inverse option '--nullglob'. See the
327 documentation for wimextract for more details and changes.
329 The wimlib_extract_files() function is now considered deprecated in
330 favor of wimlib_extract_paths().
332 Fixed more permissions problems when extracting files on Windows.
334 A new '--no-attributes' option has been added to wimapply and
335 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
337 The default chunk size is now set correctly when changing the
338 compression type of a WIM, for example with 'wimoptimize'.
340 The '--metadata' option to wiminfo has been replaced with the
341 '--detailed' option to wimdir.
343 In relevant wimlib-imagex commands, '--solid' may now be used as an
344 alias for '--pack-streams'.
347 Support for extracting and updating the new version 3584 WIMs has been
348 added. These WIMs typically pack many streams ("files") together into a
349 single compressed resource, thereby saving space. This degrades the
350 performance of random access (such as that which occurs on a mounted
351 image), but optimizations have been implemented for extraction. These
352 new WIM files also typically use a new compression format (LZMS), which
353 is similar to LZMA and can offer a better compression ratio than LZX.
354 These new WIM files can be created using `wimcapture' with
355 the '--compress=lzms --pack-streams' options. Note: this new WIM format
356 is used by the Windows 8 web downloader, but important segments of the
357 raw '.esd' files are encrypted, so wimlib will not be able to extract
358 such files until they are first decrypted.
360 wimlib now supports extracting files and directories from a WIM image
361 based on a "listfile" that itself contains the list of paths to extract.
362 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
363 and for the library itself, the new APIs are wimlib_extract_pathlist()
364 and wimlib_extract_paths(). Path globs containing wildcard characters
367 For searching WIM files, wimlib now has configurable case sensitivity.
368 The default on Windows is still case-insensitive and the default on
369 UNIX-like systems is still case-sensitive, but this can be overridden
370 on either platform through flags to wimlib_global_init(). For
371 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
372 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
375 Support for compression chunk sizes greater than the default of 32768
376 bytes has been added. A larger chunk size typically results in a better
377 compression ratio. However, the MS implementation is seemingly not
378 compatible with all chunk sizes, especially for LZX compression, so the
379 defaults remain unchanged, with the exception of the new LZMS-compressed
380 WIMs, which use a larger chunk size by default.
382 The compression/decompression API exported by wimlib has been changed.
383 Now one set of functions handles all supported compression formats.
385 `wimcapture' and `wimappend' will now display the progress of scanning
386 the directory tree to capture, in addition to the progress of writing
387 data to the WIM. The '--verbose' option no longer does anything. The
388 library API change for this is the addition of several members to
389 `struct wimlib_progress_info_scan' available to progress callbacks.
391 `mkwinpeimg' now correctly handles the '--start-script' option when the
392 start script is not in the working directory.
394 Sequential extraction, previously requested by using
395 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
396 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
397 behavior (extract in file order).
400 The new LZX compressor added in v1.5.2 has been improved and is now
401 enabled by default, except when `wimcapture' or `wimappend' is run
402 *without* the '--compress' option, in which case the faster LZX
403 compressor is used (the same as before). This behavior is reasonably
404 consistent with ImageX which actually uses "fast" (XPRESS) compression
405 by default. In those cases, use '--compress=maximum' to explicitly
406 capture a WIM image using the new (slower but better) LZX compressor.
408 The '--compress-slow' option still exists to `wimlib-imagex optimize',
409 but its new behavior is to tweak the new LZX compressor even more to
410 produce an even better compression ratio at the cost of more time spent
413 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
414 which recompresses the WIM file using the specified compression TYPE.
415 The new library API function used for this is
416 wimlib_set_output_compression_type().
418 Added the wimlib_get_xml_data() function to allow library clients to
419 easily retrieve the raw XML data from a WIM file if needed.
421 Fixed a bug that could cause an error code to be incorrectly returned
422 when writing XML data containing a <WINDOWS> element.
424 Mounted WIM images will now correctly show the default file stream even
425 if appears in the alternate data stream entries of the corresponding WIM
429 Added a new experimental LZX compressor which can be enabled by passing
430 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
431 optimize'. (The latter is only applicable if the WIM is already
432 LZX-compressed and the '--recompress' option is also given.) The
433 experimental compressor is much slower but compresses the data slightly
434 more --- currently usually to within a fraction of a percent of the
435 results from WIMGAPI/ImageX.
437 A workaround has been added for compatibility with versions of WinPE
438 that interpret alternate data stream entries in the boot WIM
441 An alignment bug that caused a crash in the LZX decompressor on some
444 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
445 the WIM header when restoring the previous state of a WIM it failed to
448 Added a workaround to avoid an access denied error on Windows when
449 replacing a WIM file that another process has opened.
452 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
453 needed to be handled.
455 A bug in the interpretation of negative IMAGE indices in the
456 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
457 `wimlib-imagex append' has been fixed.
459 A workaround has been added to successfully apply security descriptors
460 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
461 2013.1.13 or earlier.
463 `wimlib-imagex capture' can now accept the '--delta-from' option
467 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
468 to standard output and applying images from standard input, but they are
469 not compatible with Microsoft's software and are not created by default.
470 See the documentation for --pipable flag of `wimlib-imagex capture' for
473 To better support incremental backups, added support for declaring an
474 image as a modified form of another image. See the documentation for
475 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
478 Added supported for "delta" WIMs. See the documentation for the
479 '--delta-from' option of `wimlib-imagex capture'.
481 The library support for managing split WIMs has been changed to support
482 other arrangements, such as delta WIMs, and be easier to use. This
483 change is visible in `wimlib-imagex', which also can now accept the
484 '--ref' option multiple times, and also now supports "delta" WIMs as
487 wimlib now preserves WIM integrity tables by default, even if
488 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
489 behavior of `wimlib-imagex' whenever the WIM being operated on contains
490 an integrity table and the '--check' option is not specified.
492 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
493 (when --compress is not specified). This provides the best compression
494 ratio by default, which is usually what is desired, at a cost of some
497 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
498 is the command as in `wimlib-imagex COMMAND'; for example, it can be
499 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
500 appropriate hard links are created in UNIX installations of
501 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
502 batch files that emulate this behavior are generated.
504 Security descriptors are now extracted correctly on Windows.
506 Fixed archiving DOS names in NTFS-3g capture mode.
508 The extraction code has been rewritten and it will now be easier to
509 support new features on all supported backends (currently Win32, UNIX,
510 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
511 now supported on all backends, not just UNIX.
513 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
514 than the WAIK itself.
516 wimlib_global_init() now, by default, attempts to acquire additional
517 privileges on Windows, so library clients need not do this.
519 This update bumps the shared library version number up to 9, since it is
520 not binary compatibible with previous releases.
523 Fixed bug in `wimlib-imagex export' that made it impossible to export an
524 image from a WIM that is readonly at the filesystem level.
526 Return error code rather than segfaulting when trying to list files from
527 a non-first part of a split WIM.
529 Joining a WIM will now preserve the RP_FIX and READONLY flags.
532 On Windows, paths given to wimlib-imagex are now treated case
535 Improved behavior regarding invalid filenames; in particular, on
536 Windows, wimlib-imagex will, when extracting, now omit (with an option
537 to override this default) filenames differing only in case, or filenames
538 containing characters not valid on Windows.
540 On Windows, wimlib now supports capturing and extracting long paths
541 (longer than the so-called MAX_PATH).
543 On Windows, `wimlib-imagex update' now acquires proper privileges when
544 running as an Administrator.
546 `wimlib-imagex update' will now complain if no image is specified when
547 trying to update a multi-image WIM.
549 `wimlib-imagex update' now supports specifying a single update command
550 directly on the command line using the --command option.
552 wimlib-imagex will now choose different units for progress messages,
553 depending on the amount of data that needs to be processed.
555 `wimlib-imagex append' will now generate a unique WIM image name if no
556 name is specified and the defaulted name already exists in the WIM.
558 wimlib now allows you to create unnamed WIM images, which can then only
559 be referred to by index.
561 wimlib now allows you to explicitly declare you want write access to a
562 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
565 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
568 Progress callbacks have been added to wimlib's wimlib_update_image()
571 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
572 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
575 NTFS-3g capture now only warns about two conditions previously treated
578 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
581 wimlib now correctly detects and returns an error when reading a WIM
582 image with a cyclic directory structure. (Fun fact: such a WIM will
583 crash Microsoft's software.)
586 Added new "extract" and "update" subcommands to wimlib-imagex, along
587 with associated APIs in the library. These commands are intended mainly
588 for Windows use but can be used on UNIX as well.
590 Many documentation improvements.
592 Fixed a bug in the Windows build where relative symbolic links were not
593 captured in reparse-point fixup mode.
595 Fixed a bug in the Windows build where file handles were left open to
596 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
598 Fixed a bug in the Windows build of wimlib-imagex where globbing
599 split-WIM parts could cause the program to crash.
601 Fixed a bug where the creation time of WIM images would be shown instead
602 of the last modification time.
604 With the Windows build it is now possible to restore a WIM containing
605 symbolic links as a non-Administrator; however you will receive warnings
606 about not being able to extract the symbolic links.
609 Capturing a WIM image should now be significantly faster in most cases
610 due to improved use of the operating system's cache and avoiding reading
611 files twice whenever possible.
613 The Windows build should now work on Windows XP.
615 The Windows build now supports capturing and restoring hidden,
616 compressed, sparse, and encrypted files.
618 The Windows build now supports capturing and applying WIM images from
619 filesystems other than NTFS (with some reduced functionality).
621 The Windows build now extracts short names correctly.
623 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
624 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
625 capture' and `wimlib-imagex apply'.
627 The performance of splitting and joining WIMs should be slightly
630 The LZX and XPRESS compression and decompression functions are now
631 exported from the library.
634 Improvements and bugfixes for the Windows build.
636 Added --strict-acls options.
638 Fixed the way that wimlib determines the order of images in the WIM.
641 Since wimlib can now be used on Windows, wimlib's implementation of
642 ImageX has been renamed to wimlib-imagex to avoid confusion with
643 Microsoft's implementation of ImageX, which would have the same file
644 name ("imagex.exe"). If you really don't like this you can pass the
645 --with-imagex-progname option to `configure' to choose a different name,
646 or even simply rename the binary yourself (but the former way will
647 configure the man pages to use the chosen name).
649 Various bugs fixed in the Windows build. Mainly to do with capturing
650 and restoring alternate data streams correctly in weird cases, and
651 requesting the correct privileges when opening files. Also added the
652 --noacls options to wimlib-imagex capture, append, and apply.
654 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
655 dynamically loaded, so this may make the library compatible with Windows
656 XP (however, there may still be other problems).
659 Added experimental support for native Windows builds. Binaries can be
660 downloaded from the SourceForge page.
662 --source-list option added to `imagex capture' and `imagex append'.
664 Better support for different character encodings.
667 Storing UNIX file owners, groups, and modes in WIM images is now
668 possible using `imagex capture' with the --unix-data flag.
670 Minor bug fixes and documentation fixes.
673 NTFS capture: Fixed capturing duplicate reparse points.
675 NTFS capture: Capture first unnamed stream if there are more than one
676 (print warning instead of error).
678 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
681 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
684 Update to work with ntfs-3g version 2013.1.13.
687 Fixed truncating file to shorter but non-zero length on read-write
690 Various code cleanups and minor documentation fixes.
693 LZX and XPRESS decompression have received some additional optimizations
694 and should now be even faster. (Although, they were already pretty
695 fast--- much faster than typical I/O speeds.)
697 Fixed a bug introduced in v1.2.1 that would cause a directory tree
698 containing hard links to be captured incorrectly in some cases.
701 By default, unmounting a read-write mounted WIM with 'imagex unmount
702 --commit' will now change the WIM in-place without needing to write the
703 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
706 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
707 for a response from the daemon servicing the mounted WIM. Instead,
708 every second 'imagex unmount' will check if the daemon is still alive,
709 and keep waiting if so, otherwise terminate with an error.
711 'imagex unmount --commit' on a read-write mounted WIM will now print
712 progress information regarding the writing of new or modified streams
713 the WIM, just like when capturing or appending a WIM.
715 A small change has been made to XPRESS compression and it should improve
716 the compression ratio slightly.
718 A change was made that may improve performance slightly when applying a
719 WIM image to a NTFS volume.
721 Microsoft has managed to introduce even more bugs into their software,
722 and now the WIMs for Windows 8 have incorrect (too low) reference counts
723 for some streams. This is unsafe because such streams can be removed
724 when they are in actuality still referenced in the WIM (perhaps by a
725 different image). wimlib will now work around this problem by fixing
726 the stream reference counts. This is only done when wimlib_delete_image() is
727 called ('imagex delete') or when wimlib_mount_image() is called with
728 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
729 requires reading the metadata for all images in the WIM, so this will
730 make these operations noticably slower on WIMs with multiple images.
732 Various other bugfixes.
735 Appending images to a WIM is now be done by default without re-building
736 the whole WIM. Use the --rebuild flag to get the old behavior (which
737 was to re-build the entire WIM when a new image is appended).
739 A new command `imagex optimize' is now available to manually re-build a
740 WIM that has wasted space due to repeated appends.
742 Progress information has been improved, and now arbitrary callback
743 functions can be used to show the progress of a WIM operation.
745 A possible bug with changing the bootable image of a WIM was fixed.
747 Some advisory locking is now done to prevent two processes from
748 modifying a WIM at the same time (but only in some cases). For example,
749 you cannot mount two images from a WIM read-write at the same time.
751 Some functions have been reorganized:
752 * wimlib_mount() renamed to wimlib_mount_image().
753 * wimlib_unmount() renamed to wimlib_unmount_image().
754 * wimlib_overwrite_xml_and_header() removed as
755 wimlib_overwrite() suffices now.
756 * wimlib_apply_image_to_ntfs_volume() removed as
757 wimlib_extract_image() suffices now.
758 * wimlib_add_image_from_ntfs_volume() removed as
759 * wimlib_add_image() suffices now.
761 Previously, the soname of libwim.so has been 0.0.0, despite many
762 interface changes. The soname is now updated to 1.0.0 and will now be
763 updated each release.
766 Resources will now be compressed using multiple threads by default.
767 (This applies to `imagex capture', `imagex append', and `imagex
770 Some performance improvements in mounted WIMs.
772 More progress information is shown when capturing a WIM.
775 Lots of minor fixes, code cleanups, and some documentation updates.
776 Nothing in particular is really noteworthy.
779 LZX and XPRESS compression improvements.
781 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
782 Link Bytes of the WIM.
785 Fixed bug when capturing NTFS file with multiple named data streams.
787 Internally, we are now using inode structures, even though these don't
788 appear literally in the WIM file. This simplifies some of the code
789 (mainly for WIM mounting) and likely fixed a few problems, although it
793 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
797 Enough changes to call it version 1.0.0!
799 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
800 to a NTFS volume, is now supported.
802 Hard links and symbolic links have much improved support. They are
803 supported for WIM capture, WIM application, and mounted WIMs (you can
804 even make them on read-write mounted WIMs).
806 Alternate data streams are now supported on mounted WIMs through an
807 xattr or a Windows-style stream interface. Also they are supported when
808 capturing a WIM from NTFS or applying a WIM to NTFS.
810 Split WIMs are better supported. You may now apply an image directly
811 from a split WIM, mount an image from a split WIM read-only, or export
812 an image from a split WIM.
814 Using a capture configuration file is now supported (but not fully yet).
816 SHA1 message digests are checked in more places, so we can make sure
817 applied and captured data is correct.
819 Man pages have been updated and consolidated.
822 Fixed segfault when unmounting read-only WIM.
825 Support for joining and splitting WIMs.
826 Also, security data is now preserved by default.
829 Can now build with older gcc and system headers, like on CentOS 5.
832 Fixed bug that made it impossible to overwrite files in read-write
836 Write byte-order mark before WIM XML data. (imagex.exe requires this to
