2 This release contains various minor bug fixes and improvements,
5 Reduced the stack space used by directory tree scans.
7 Fixed a bug where on 32-bit systems, the library could enter an
8 infinite loop if a WIM file was malformed in a specific way.
10 Windows symbolic links and junctions in mounted WIM images are
11 now automatically rewritten to be valid in the mounted location.
13 Reparse point fixes: correctly handle the "ReparseReserved"
14 field, and correctly handle "empty" (data-less) reparse points.
16 Improved validation of filenames.
18 Fixed the test scripts to work in a Turkish locale.
20 Fixed handling of EINTR during data I/O.
22 Optimized memory usage of some data structures.
25 Fixed a bug in the LZX decompressor: malicious input data could cause
26 out of bounds writes to memory (since wimlib v1.2.2).
28 The output of the 'wiminfo' command now consolidates various boolean
29 flags (such as "Relative path junction") into a single line.
31 A file can now have both an unnamed data stream ("file contents") and a
32 reparse point stream. Such files can exist as a result of the use of
33 certain Windows features, such as offline storage, including "OneDrive".
34 wimlib will now store and restore both streams on Windows as well as in
35 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
37 On Windows, named data streams of encrypted files are no longer stored
38 twice in WIM archives.
40 On Windows, named data streams are now correctly extracted to existing
41 "readonly" directories. Before, an error would be reported.
43 On Windows, it is now possible to do a "WIMBoot mode" extraction with
44 non-standalone WIMs such as delta WIMs.
46 On Windows, when doing an extraction in "WIMBoot mode", files larger
47 than 4 gigabytes are now never extracted as externally backed. This
48 works around a bug in Microsoft's "WOF" driver.
50 The '--enable-verify-compression' configure option has been removed. If
51 you want to verify a WIM file, use the 'wimverify' program.
53 The way the "file count", "directory count", "total bytes", and "hard
54 link bytes" image statistics (stored in the WIM XML data) is calculated
55 has been slightly changed.
57 In mounted WIM images, the disk usage provided for each file (st_blocks)
58 is now the compressed size rather than the uncompressed size.
60 The performance of the NTFS-3g and Windows capture modes has been
63 On UNIX-like systems, symbolic links whose targets contain the backslash
64 character are now handled correctly (losslessly).
67 Improved the LZX compressor. It is now 15-20% faster than before and
68 provides a slightly better compression ratio.
70 Improved the LZMS compressor. It now provides a compression ratio
71 slightly better than WIMGAPI while still being faster and using slightly
74 The compression chunk size in solid resources, e.g. when capturing or
75 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
76 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
77 better compression ratio and is the same value that WIMGAPI uses. The
78 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
79 lower than WIMGAPI's memory usage, but if it is too much, it is still
80 possible to choose a lower value, e.g. with the '--solid-chunk-size'
81 option to wimlib-imagex.
83 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
84 accept the 'K', 'M', and 'G' suffixes.
86 Files are now sorted by name extension when creating a solid WIM file.
88 Fixed various issues related to capture/apply of EFS-encrypted files on
91 The file list printed by 'wimdir' is now sorted by the platform-specific
92 case sensitivity setting, rather than always case sensitively. This
93 also affects the library function wimlib_iterate_dir_tree().
95 On Windows, some error and warning messages have been improved.
98 The Windows binary distribution no longer contains third party DLLs.
99 These dependencies are instead compiled directly into the libwim DLL.
101 Added more fixes for wimlib on non-x86 architectures such as ARM.
103 Extracting files to a Windows PE in-memory filesystem no longer fails if
104 the target files do not yet exist.
106 Improved the performance of XPRESS compression and LZMS decompression.
108 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
109 It will automatically be faster on newer Intel and AMD processors.
111 Removed the --with-imagex-progname and --enable-more-assertions
115 Fix for very slow export from solid WIM / ESD files.
117 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
119 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
120 may use this to treat some types of errors as non-fatal.
122 The library now permits making in-memory changes to a WIMStruct backed
123 by a read-only WIM file.
125 Fixes for "WIMBoot" extraction mode (Windows only):
127 When not using the WOF driver, extraction no longer fails if the
128 disk containing the WIM file has too many partitions.
130 When matching patterns in [PrepopulateList], all hard links of
131 each file are now considered.
133 The system registry files are now automatically treated as being
134 in [PrepopulateList].
136 Added a hack to try to work around an intermittent bug in
137 Microsoft's WOF (Windows Overlay Filesystem) driver.
140 Made more improvements to the XPRESS, LZX, and LZMS compressors.
142 A number of improvements to the Windows port:
144 Fixes for setting short filenames.
146 Faster "WIMBoot" extraction.
148 Updated and slimmed down the dependent DLLs.
150 ACL inheritence bits are now restored.
152 Mandatory integrity labels are now backed up and restored.
154 Added a workaround for an issue where in rare cases, wimlib could create
155 a compressed data stream that could not be read correctly by Windows
156 after an extraction in "WIMBoot" mode.
159 Added file count progress data for
160 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
161 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
163 Added support for testing file exclusions via the user-provided
166 Some documentation improvements.
168 Made some clarifications to the license text in the COPYING file.
171 Made more improvements to the XPRESS, LZX, and LZMS compressors.
173 The default compression mode for wimcapture is now LZX compression in
174 its default mode, which is the same as '--compress=maximum'.
176 You can now specify an optional integer compression level to the
177 '--compress' option; e.g. '--compress=lzx:75'.
179 Made a minor change to the LZMS compressor and decompressor to fix an
180 incompatibility with the Microsoft implementation. In the unlikely
181 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
182 earlier and a checksum error is reported when extracting files from it
183 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
186 Added 'verify' subcommand to wimlib-imagex.
188 Notable library changes:
190 Custom compressor parameters have been removed from the library
191 in favor of the simpler level-based API.
193 Decompressor parameters have been removed entirely.
195 Library users can now specify a custom file for warning and
196 error messages to be sent to, rather than the default of
199 New progress messages:
200 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
201 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
203 New function: wimlib_verify_wim().
206 Improved compression, decompression, and extraction performance.
208 Improved compatibility with version 3584 WIM / ESD files:
209 - Add support for reading and writing multiple solid blocks per
210 archive, which WIMGAPI/DISM can create when appending an image.
211 - Correctly create solid blocks larger than 4 GiB.
213 'add' commands passed to wimupdate will now replace existing
214 nondirectory files by default. Use the --no-replace option to get the
217 The license for the library now contains an exception that allows using
218 it under the LGPL. See the COPYING file for details.
220 In reparse-point fixup mode (the default for capture), symbolic links
221 and junctions that point outside the tree being captured are no longer
222 excluded from capture.
224 Added support for "WIMBoot" capture and extraction. See the
225 documentation for the new '--wimboot' option to wimcapture and wimapply
226 for more information.
228 On UNIX-like systems, you can now backup and restore device nodes, named
229 pipes, and sockets. In addition, 32-bit user and group IDs are now
232 The way that UNIX data is stored in WIM files has been changed. If you
233 captured any WIMs with the --unix-data option, to upgrade them you'll
234 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
235 re-capture them with --unix-data using this version.
237 wimlib now understands tagged metadata items, such as object IDs, that
238 can be stored in WIM directory entries.
240 Removed the --hardlink and --symlink options to wimapply, since I don't
241 think they are too useful and they got in the way of improving the code.
243 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
245 The 'mkwinpeimg' script now supports writing the ISO image to standard
248 The <ARCH> element in WIM XML data is now exported correctly.
250 On Windows, sparse file attributes are no longer set on extracted files.
251 Oddly enough, this actually saves disk space in some cases.
253 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
254 supported. Mounting WIM images now always requires extended attribute
255 support. Use --without-fuse to disable support for mounting WIM images;
256 this will also disable the need for extended attribute support.
258 Configuring with --enable-ssse3-sha1 now works correctly.
260 The shared library version has been bumped up. The main
261 incompatibilities are:
263 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
264 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
267 - User-provided progress functions are now registered using a
268 separate function, wimlib_register_progress_function(). The
269 'progress_func' argument to many functions no longer exists.
271 - The return value from user-provided progress functions is now
274 - A context argument has been added to the prototype of
275 user-provided progress functions.
277 - 'struct wimlib_capture_config' has been removed. The library
278 now takes the path to the configuration file directly. This
279 affects wimlib_add_image(), wimlib_add_image_multisource(),
280 and wimlib_update_image(). However, a NULL value passed in
281 the argument retains the same meaning.
283 - Removed deprecated functions: some (de)compression functions,
284 wimlib_extract_files(), and wimlib_print_metadata().
286 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
287 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
288 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
290 - Removed some progress messages:
291 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
292 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
293 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
296 - Removed some error codes. Numbering stays the same.
298 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
299 WIMLIB_UNMOUNT_FLAG_FORCE.
301 - WIM paths passed to progress functions now have a leading
305 Case-insensitive comparisons of strings (e.g. filenames) containing
306 UTF-16 codepoints above 32767 are now done correctly.
308 Fixed build failure on Mac OS X.
310 wimunmount now provides the '--new-image' option to cause changes to a
311 read-write mounted image to be committed as a new image rather than as
312 an update of the mounted image. (The corresponding new library flag is
313 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
315 The LZMS ("recovery") compression chunk size, or "dictionary size", may
316 now be up to 1 GiB (1,073,741,824 bytes).
318 The performance of LZX ("maximum") and LZMS ("recovery") compression
319 with large chunk sizes has been slightly improved.
322 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
323 decompressed correctly.
325 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
326 occurred in an unlikely case, and due to validity checks it did not
327 affect successfully created archives.
329 Fixed a minor compatibility issue with the LZMS compressor and
330 decompressor. This is *not* the default compression type and was only
331 introduced in v1.6.0. In the unlikely event that you created an
332 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
333 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
336 Memory usage for LZMS and LZX compression has been decreased.
338 wimextract now allows wildcard characters in paths specified on the
339 command line. Also, the '--strict-wildcards' option has been removed
340 and replaced with the inverse option '--nullglob'. See the
341 documentation for wimextract for more details and changes.
343 The wimlib_extract_files() function is now considered deprecated in
344 favor of wimlib_extract_paths().
346 Fixed more permissions problems when extracting files on Windows.
348 A new '--no-attributes' option has been added to wimapply and
349 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
351 The default chunk size is now set correctly when changing the
352 compression type of a WIM, for example with 'wimoptimize'.
354 The '--metadata' option to wiminfo has been replaced with the
355 '--detailed' option to wimdir.
357 In relevant wimlib-imagex commands, '--solid' may now be used as an
358 alias for '--pack-streams'.
361 Support for extracting and updating the new version 3584 WIMs has been
362 added. These WIMs typically pack many streams ("files") together into a
363 single compressed resource, thereby saving space. This degrades the
364 performance of random access (such as that which occurs on a mounted
365 image), but optimizations have been implemented for extraction. These
366 new WIM files also typically use a new compression format (LZMS), which
367 is similar to LZMA and can offer a better compression ratio than LZX.
368 These new WIM files can be created using `wimcapture' with
369 the '--compress=lzms --pack-streams' options. Note: this new WIM format
370 is used by the Windows 8 web downloader, but important segments of the
371 raw '.esd' files are encrypted, so wimlib will not be able to extract
372 such files until they are first decrypted.
374 wimlib now supports extracting files and directories from a WIM image
375 based on a "listfile" that itself contains the list of paths to extract.
376 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
377 and for the library itself, the new APIs are wimlib_extract_pathlist()
378 and wimlib_extract_paths(). Path globs containing wildcard characters
381 For searching WIM files, wimlib now has configurable case sensitivity.
382 The default on Windows is still case-insensitive and the default on
383 UNIX-like systems is still case-sensitive, but this can be overridden
384 on either platform through flags to wimlib_global_init(). For
385 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
386 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
389 Support for compression chunk sizes greater than the default of 32768
390 bytes has been added. A larger chunk size typically results in a better
391 compression ratio. However, the MS implementation is seemingly not
392 compatible with all chunk sizes, especially for LZX compression, so the
393 defaults remain unchanged, with the exception of the new LZMS-compressed
394 WIMs, which use a larger chunk size by default.
396 The compression/decompression API exported by wimlib has been changed.
397 Now one set of functions handles all supported compression formats.
399 `wimcapture' and `wimappend' will now display the progress of scanning
400 the directory tree to capture, in addition to the progress of writing
401 data to the WIM. The '--verbose' option no longer does anything. The
402 library API change for this is the addition of several members to
403 `struct wimlib_progress_info_scan' available to progress callbacks.
405 `mkwinpeimg' now correctly handles the '--start-script' option when the
406 start script is not in the working directory.
408 Sequential extraction, previously requested by using
409 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
410 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
411 behavior (extract in file order).
414 The new LZX compressor added in v1.5.2 has been improved and is now
415 enabled by default, except when `wimcapture' or `wimappend' is run
416 *without* the '--compress' option, in which case the faster LZX
417 compressor is used (the same as before). This behavior is reasonably
418 consistent with ImageX which actually uses "fast" (XPRESS) compression
419 by default. In those cases, use '--compress=maximum' to explicitly
420 capture a WIM image using the new (slower but better) LZX compressor.
422 The '--compress-slow' option still exists to `wimlib-imagex optimize',
423 but its new behavior is to tweak the new LZX compressor even more to
424 produce an even better compression ratio at the cost of more time spent
427 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
428 which recompresses the WIM file using the specified compression TYPE.
429 The new library API function used for this is
430 wimlib_set_output_compression_type().
432 Added the wimlib_get_xml_data() function to allow library clients to
433 easily retrieve the raw XML data from a WIM file if needed.
435 Fixed a bug that could cause an error code to be incorrectly returned
436 when writing XML data containing a <WINDOWS> element.
438 Mounted WIM images will now correctly show the default file stream even
439 if appears in the alternate data stream entries of the corresponding WIM
443 Added a new experimental LZX compressor which can be enabled by passing
444 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
445 optimize'. (The latter is only applicable if the WIM is already
446 LZX-compressed and the '--recompress' option is also given.) The
447 experimental compressor is much slower but compresses the data slightly
448 more --- currently usually to within a fraction of a percent of the
449 results from WIMGAPI/ImageX.
451 A workaround has been added for compatibility with versions of WinPE
452 that interpret alternate data stream entries in the boot WIM
455 An alignment bug that caused a crash in the LZX decompressor on some
458 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
459 the WIM header when restoring the previous state of a WIM it failed to
462 Added a workaround to avoid an access denied error on Windows when
463 replacing a WIM file that another process has opened.
466 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
467 needed to be handled.
469 A bug in the interpretation of negative IMAGE indices in the
470 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
471 `wimlib-imagex append' has been fixed.
473 A workaround has been added to successfully apply security descriptors
474 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
475 2013.1.13 or earlier.
477 `wimlib-imagex capture' can now accept the '--delta-from' option
481 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
482 to standard output and applying images from standard input, but they are
483 not compatible with Microsoft's software and are not created by default.
484 See the documentation for --pipable flag of `wimlib-imagex capture' for
487 To better support incremental backups, added support for declaring an
488 image as a modified form of another image. See the documentation for
489 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
492 Added supported for "delta" WIMs. See the documentation for the
493 '--delta-from' option of `wimlib-imagex capture'.
495 The library support for managing split WIMs has been changed to support
496 other arrangements, such as delta WIMs, and be easier to use. This
497 change is visible in `wimlib-imagex', which also can now accept the
498 '--ref' option multiple times, and also now supports "delta" WIMs as
501 wimlib now preserves WIM integrity tables by default, even if
502 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
503 behavior of `wimlib-imagex' whenever the WIM being operated on contains
504 an integrity table and the '--check' option is not specified.
506 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
507 (when --compress is not specified). This provides the best compression
508 ratio by default, which is usually what is desired, at a cost of some
511 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
512 is the command as in `wimlib-imagex COMMAND'; for example, it can be
513 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
514 appropriate hard links are created in UNIX installations of
515 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
516 batch files that emulate this behavior are generated.
518 Security descriptors are now extracted correctly on Windows.
520 Fixed archiving DOS names in NTFS-3g capture mode.
522 The extraction code has been rewritten and it will now be easier to
523 support new features on all supported backends (currently Win32, UNIX,
524 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
525 now supported on all backends, not just UNIX.
527 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
528 than the WAIK itself.
530 wimlib_global_init() now, by default, attempts to acquire additional
531 privileges on Windows, so library clients need not do this.
533 This update bumps the shared library version number up to 9, since it is
534 not binary compatibible with previous releases.
537 Fixed bug in `wimlib-imagex export' that made it impossible to export an
538 image from a WIM that is readonly at the filesystem level.
540 Return error code rather than segfaulting when trying to list files from
541 a non-first part of a split WIM.
543 Joining a WIM will now preserve the RP_FIX and READONLY flags.
546 On Windows, paths given to wimlib-imagex are now treated case
549 Improved behavior regarding invalid filenames; in particular, on
550 Windows, wimlib-imagex will, when extracting, now omit (with an option
551 to override this default) filenames differing only in case, or filenames
552 containing characters not valid on Windows.
554 On Windows, wimlib now supports capturing and extracting long paths
555 (longer than the so-called MAX_PATH).
557 On Windows, `wimlib-imagex update' now acquires proper privileges when
558 running as an Administrator.
560 `wimlib-imagex update' will now complain if no image is specified when
561 trying to update a multi-image WIM.
563 `wimlib-imagex update' now supports specifying a single update command
564 directly on the command line using the --command option.
566 wimlib-imagex will now choose different units for progress messages,
567 depending on the amount of data that needs to be processed.
569 `wimlib-imagex append' will now generate a unique WIM image name if no
570 name is specified and the defaulted name already exists in the WIM.
572 wimlib now allows you to create unnamed WIM images, which can then only
573 be referred to by index.
575 wimlib now allows you to explicitly declare you want write access to a
576 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
579 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
582 Progress callbacks have been added to wimlib's wimlib_update_image()
585 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
586 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
589 NTFS-3g capture now only warns about two conditions previously treated
592 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
595 wimlib now correctly detects and returns an error when reading a WIM
596 image with a cyclic directory structure. (Fun fact: such a WIM will
597 crash Microsoft's software.)
600 Added new "extract" and "update" subcommands to wimlib-imagex, along
601 with associated APIs in the library. These commands are intended mainly
602 for Windows use but can be used on UNIX as well.
604 Many documentation improvements.
606 Fixed a bug in the Windows build where relative symbolic links were not
607 captured in reparse-point fixup mode.
609 Fixed a bug in the Windows build where file handles were left open to
610 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
612 Fixed a bug in the Windows build of wimlib-imagex where globbing
613 split-WIM parts could cause the program to crash.
615 Fixed a bug where the creation time of WIM images would be shown instead
616 of the last modification time.
618 With the Windows build it is now possible to restore a WIM containing
619 symbolic links as a non-Administrator; however you will receive warnings
620 about not being able to extract the symbolic links.
623 Capturing a WIM image should now be significantly faster in most cases
624 due to improved use of the operating system's cache and avoiding reading
625 files twice whenever possible.
627 The Windows build should now work on Windows XP.
629 The Windows build now supports capturing and restoring hidden,
630 compressed, sparse, and encrypted files.
632 The Windows build now supports capturing and applying WIM images from
633 filesystems other than NTFS (with some reduced functionality).
635 The Windows build now extracts short names correctly.
637 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
638 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
639 capture' and `wimlib-imagex apply'.
641 The performance of splitting and joining WIMs should be slightly
644 The LZX and XPRESS compression and decompression functions are now
645 exported from the library.
648 Improvements and bugfixes for the Windows build.
650 Added --strict-acls options.
652 Fixed the way that wimlib determines the order of images in the WIM.
655 Since wimlib can now be used on Windows, wimlib's implementation of
656 ImageX has been renamed to wimlib-imagex to avoid confusion with
657 Microsoft's implementation of ImageX, which would have the same file
658 name ("imagex.exe"). If you really don't like this you can pass the
659 --with-imagex-progname option to `configure' to choose a different name,
660 or even simply rename the binary yourself (but the former way will
661 configure the man pages to use the chosen name).
663 Various bugs fixed in the Windows build. Mainly to do with capturing
664 and restoring alternate data streams correctly in weird cases, and
665 requesting the correct privileges when opening files. Also added the
666 --noacls options to wimlib-imagex capture, append, and apply.
668 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
669 dynamically loaded, so this may make the library compatible with Windows
670 XP (however, there may still be other problems).
673 Added experimental support for native Windows builds. Binaries can be
674 downloaded from the SourceForge page.
676 --source-list option added to `imagex capture' and `imagex append'.
678 Better support for different character encodings.
681 Storing UNIX file owners, groups, and modes in WIM images is now
682 possible using `imagex capture' with the --unix-data flag.
684 Minor bug fixes and documentation fixes.
687 NTFS capture: Fixed capturing duplicate reparse points.
689 NTFS capture: Capture first unnamed stream if there are more than one
690 (print warning instead of error).
692 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
695 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
698 Update to work with ntfs-3g version 2013.1.13.
701 Fixed truncating file to shorter but non-zero length on read-write
704 Various code cleanups and minor documentation fixes.
707 LZX and XPRESS decompression have received some additional optimizations
708 and should now be even faster. (Although, they were already pretty
709 fast--- much faster than typical I/O speeds.)
711 Fixed a bug introduced in v1.2.1 that would cause a directory tree
712 containing hard links to be captured incorrectly in some cases.
715 By default, unmounting a read-write mounted WIM with 'imagex unmount
716 --commit' will now change the WIM in-place without needing to write the
717 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
720 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
721 for a response from the daemon servicing the mounted WIM. Instead,
722 every second 'imagex unmount' will check if the daemon is still alive,
723 and keep waiting if so, otherwise terminate with an error.
725 'imagex unmount --commit' on a read-write mounted WIM will now print
726 progress information regarding the writing of new or modified streams
727 the WIM, just like when capturing or appending a WIM.
729 A small change has been made to XPRESS compression and it should improve
730 the compression ratio slightly.
732 A change was made that may improve performance slightly when applying a
733 WIM image to a NTFS volume.
735 Microsoft has managed to introduce even more bugs into their software,
736 and now the WIMs for Windows 8 have incorrect (too low) reference counts
737 for some streams. This is unsafe because such streams can be removed
738 when they are in actuality still referenced in the WIM (perhaps by a
739 different image). wimlib will now work around this problem by fixing
740 the stream reference counts. This is only done when wimlib_delete_image() is
741 called ('imagex delete') or when wimlib_mount_image() is called with
742 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
743 requires reading the metadata for all images in the WIM, so this will
744 make these operations noticably slower on WIMs with multiple images.
746 Various other bugfixes.
749 Appending images to a WIM is now be done by default without re-building
750 the whole WIM. Use the --rebuild flag to get the old behavior (which
751 was to re-build the entire WIM when a new image is appended).
753 A new command `imagex optimize' is now available to manually re-build a
754 WIM that has wasted space due to repeated appends.
756 Progress information has been improved, and now arbitrary callback
757 functions can be used to show the progress of a WIM operation.
759 A possible bug with changing the bootable image of a WIM was fixed.
761 Some advisory locking is now done to prevent two processes from
762 modifying a WIM at the same time (but only in some cases). For example,
763 you cannot mount two images from a WIM read-write at the same time.
765 Some functions have been reorganized:
766 * wimlib_mount() renamed to wimlib_mount_image().
767 * wimlib_unmount() renamed to wimlib_unmount_image().
768 * wimlib_overwrite_xml_and_header() removed as
769 wimlib_overwrite() suffices now.
770 * wimlib_apply_image_to_ntfs_volume() removed as
771 wimlib_extract_image() suffices now.
772 * wimlib_add_image_from_ntfs_volume() removed as
773 * wimlib_add_image() suffices now.
775 Previously, the soname of libwim.so has been 0.0.0, despite many
776 interface changes. The soname is now updated to 1.0.0 and will now be
777 updated each release.
780 Resources will now be compressed using multiple threads by default.
781 (This applies to `imagex capture', `imagex append', and `imagex
784 Some performance improvements in mounted WIMs.
786 More progress information is shown when capturing a WIM.
789 Lots of minor fixes, code cleanups, and some documentation updates.
790 Nothing in particular is really noteworthy.
793 LZX and XPRESS compression improvements.
795 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
796 Link Bytes of the WIM.
799 Fixed bug when capturing NTFS file with multiple named data streams.
801 Internally, we are now using inode structures, even though these don't
802 appear literally in the WIM file. This simplifies some of the code
803 (mainly for WIM mounting) and likely fixed a few problems, although it
807 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
811 Enough changes to call it version 1.0.0!
813 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
814 to a NTFS volume, is now supported.
816 Hard links and symbolic links have much improved support. They are
817 supported for WIM capture, WIM application, and mounted WIMs (you can
818 even make them on read-write mounted WIMs).
820 Alternate data streams are now supported on mounted WIMs through an
821 xattr or a Windows-style stream interface. Also they are supported when
822 capturing a WIM from NTFS or applying a WIM to NTFS.
824 Split WIMs are better supported. You may now apply an image directly
825 from a split WIM, mount an image from a split WIM read-only, or export
826 an image from a split WIM.
828 Using a capture configuration file is now supported (but not fully yet).
830 SHA1 message digests are checked in more places, so we can make sure
831 applied and captured data is correct.
833 Man pages have been updated and consolidated.
836 Fixed segfault when unmounting read-only WIM.
839 Support for joining and splitting WIMs.
840 Also, security data is now preserved by default.
843 Can now build with older gcc and system headers, like on CentOS 5.
846 Fixed bug that made it impossible to overwrite files in read-write
850 Write byte-order mark before WIM XML data. (imagex.exe requires this to
