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