2 This release primarily contains various minor bug fixes and
3 improvements, including:
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.
24 Improved LZMS decompression speed.
26 The configure script now honors alternate pkg-config settings.
28 In addition, *experimental* support has been added for compressing
29 extracted files using System Compression on Windows 10. This
30 functionality is available through the new '--compact' option to
31 'wimapply' and 'wimextract' as well as new library flags.
34 Fixed a bug in the LZX decompressor: malicious input data could cause
35 out of bounds writes to memory (since wimlib v1.2.2).
37 The output of the 'wiminfo' command now consolidates various boolean
38 flags (such as "Relative path junction") into a single line.
40 A file can now have both an unnamed data stream ("file contents") and a
41 reparse point stream. Such files can exist as a result of the use of
42 certain Windows features, such as offline storage, including "OneDrive".
43 wimlib will now store and restore both streams on Windows as well as in
44 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
46 On Windows, named data streams of encrypted files are no longer stored
47 twice in WIM archives.
49 On Windows, named data streams are now correctly extracted to existing
50 "readonly" directories. Before, an error would be reported.
52 On Windows, it is now possible to do a "WIMBoot mode" extraction with
53 non-standalone WIMs such as delta WIMs.
55 On Windows, when doing an extraction in "WIMBoot mode", files larger
56 than 4 gigabytes are now never extracted as externally backed. This
57 works around a bug in Microsoft's "WOF" driver.
59 The '--enable-verify-compression' configure option has been removed. If
60 you want to verify a WIM file, use the 'wimverify' program.
62 The way the "file count", "directory count", "total bytes", and "hard
63 link bytes" image statistics (stored in the WIM XML data) is calculated
64 has been slightly changed.
66 In mounted WIM images, the disk usage provided for each file (st_blocks)
67 is now the compressed size rather than the uncompressed size.
69 The performance of the NTFS-3g and Windows capture modes has been
72 On UNIX-like systems, symbolic links whose targets contain the backslash
73 character are now handled correctly (losslessly).
76 Improved the LZX compressor. It is now 15-20% faster than before and
77 provides a slightly better compression ratio.
79 Improved the LZMS compressor. It now provides a compression ratio
80 slightly better than WIMGAPI while still being faster and using slightly
83 The compression chunk size in solid resources, e.g. when capturing or
84 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
85 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
86 better compression ratio and is the same value that WIMGAPI uses. The
87 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
88 lower than WIMGAPI's memory usage, but if it is too much, it is still
89 possible to choose a lower value, e.g. with the '--solid-chunk-size'
90 option to wimlib-imagex.
92 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
93 accept the 'K', 'M', and 'G' suffixes.
95 Files are now sorted by name extension when creating a solid WIM file.
97 Fixed various issues related to capture/apply of EFS-encrypted files on
100 The file list printed by 'wimdir' is now sorted by the platform-specific
101 case sensitivity setting, rather than always case sensitively. This
102 also affects the library function wimlib_iterate_dir_tree().
104 On Windows, some error and warning messages have been improved.
107 The Windows binary distribution no longer contains third party DLLs.
108 These dependencies are instead compiled directly into the libwim DLL.
110 Added more fixes for wimlib on non-x86 architectures such as ARM.
112 Extracting files to a Windows PE in-memory filesystem no longer fails if
113 the target files do not yet exist.
115 Improved the performance of XPRESS compression and LZMS decompression.
117 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
118 It will automatically be faster on newer Intel and AMD processors.
120 Removed the --with-imagex-progname and --enable-more-assertions
124 Fix for very slow export from solid WIM / ESD files.
126 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
128 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
129 may use this to treat some types of errors as non-fatal.
131 The library now permits making in-memory changes to a WIMStruct backed
132 by a read-only WIM file.
134 Fixes for "WIMBoot" extraction mode (Windows only):
136 When not using the WOF driver, extraction no longer fails if the
137 disk containing the WIM file has too many partitions.
139 When matching patterns in [PrepopulateList], all hard links of
140 each file are now considered.
142 The system registry files are now automatically treated as being
143 in [PrepopulateList].
145 Added a hack to try to work around an intermittent bug in
146 Microsoft's WOF (Windows Overlay Filesystem) driver.
149 Made more improvements to the XPRESS, LZX, and LZMS compressors.
151 A number of improvements to the Windows port:
153 Fixes for setting short filenames.
155 Faster "WIMBoot" extraction.
157 Updated and slimmed down the dependent DLLs.
159 ACL inheritence bits are now restored.
161 Mandatory integrity labels are now backed up and restored.
163 Added a workaround for an issue where in rare cases, wimlib could create
164 a compressed data stream that could not be read correctly by Windows
165 after an extraction in "WIMBoot" mode.
168 Added file count progress data for
169 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
170 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
172 Added support for testing file exclusions via the user-provided
175 Some documentation improvements.
177 Made some clarifications to the license text in the COPYING file.
180 Made more improvements to the XPRESS, LZX, and LZMS compressors.
182 The default compression mode for wimcapture is now LZX compression in
183 its default mode, which is the same as '--compress=maximum'.
185 You can now specify an optional integer compression level to the
186 '--compress' option; e.g. '--compress=lzx:75'.
188 Made a minor change to the LZMS compressor and decompressor to fix an
189 incompatibility with the Microsoft implementation. In the unlikely
190 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
191 earlier and a checksum error is reported when extracting files from it
192 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
195 Added 'verify' subcommand to wimlib-imagex.
197 Notable library changes:
199 Custom compressor parameters have been removed from the library
200 in favor of the simpler level-based API.
202 Decompressor parameters have been removed entirely.
204 Library users can now specify a custom file for warning and
205 error messages to be sent to, rather than the default of
208 New progress messages:
209 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
210 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
212 New function: wimlib_verify_wim().
215 Improved compression, decompression, and extraction performance.
217 Improved compatibility with version 3584 WIM / ESD files:
218 - Add support for reading and writing multiple solid blocks per
219 archive, which WIMGAPI/DISM can create when appending an image.
220 - Correctly create solid blocks larger than 4 GiB.
222 'add' commands passed to wimupdate will now replace existing
223 nondirectory files by default. Use the --no-replace option to get the
226 The license for the library now contains an exception that allows using
227 it under the LGPL. See the COPYING file for details.
229 In reparse-point fixup mode (the default for capture), symbolic links
230 and junctions that point outside the tree being captured are no longer
231 excluded from capture.
233 Added support for "WIMBoot" capture and extraction. See the
234 documentation for the new '--wimboot' option to wimcapture and wimapply
235 for more information.
237 On UNIX-like systems, you can now backup and restore device nodes, named
238 pipes, and sockets. In addition, 32-bit user and group IDs are now
241 The way that UNIX data is stored in WIM files has been changed. If you
242 captured any WIMs with the --unix-data option, to upgrade them you'll
243 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
244 re-capture them with --unix-data using this version.
246 wimlib now understands tagged metadata items, such as object IDs, that
247 can be stored in WIM directory entries.
249 Removed the --hardlink and --symlink options to wimapply, since I don't
250 think they are too useful and they got in the way of improving the code.
252 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
254 The 'mkwinpeimg' script now supports writing the ISO image to standard
257 The <ARCH> element in WIM XML data is now exported correctly.
259 On Windows, sparse file attributes are no longer set on extracted files.
260 Oddly enough, this actually saves disk space in some cases.
262 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
263 supported. Mounting WIM images now always requires extended attribute
264 support. Use --without-fuse to disable support for mounting WIM images;
265 this will also disable the need for extended attribute support.
267 Configuring with --enable-ssse3-sha1 now works correctly.
269 The shared library version has been bumped up. The main
270 incompatibilities are:
272 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
273 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
276 - User-provided progress functions are now registered using a
277 separate function, wimlib_register_progress_function(). The
278 'progress_func' argument to many functions no longer exists.
280 - The return value from user-provided progress functions is now
283 - A context argument has been added to the prototype of
284 user-provided progress functions.
286 - 'struct wimlib_capture_config' has been removed. The library
287 now takes the path to the configuration file directly. This
288 affects wimlib_add_image(), wimlib_add_image_multisource(),
289 and wimlib_update_image(). However, a NULL value passed in
290 the argument retains the same meaning.
292 - Removed deprecated functions: some (de)compression functions,
293 wimlib_extract_files(), and wimlib_print_metadata().
295 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
296 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
297 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
299 - Removed some progress messages:
300 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
301 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
302 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
305 - Removed some error codes. Numbering stays the same.
307 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
308 WIMLIB_UNMOUNT_FLAG_FORCE.
310 - WIM paths passed to progress functions now have a leading
314 Case-insensitive comparisons of strings (e.g. filenames) containing
315 UTF-16 codepoints above 32767 are now done correctly.
317 Fixed build failure on Mac OS X.
319 wimunmount now provides the '--new-image' option to cause changes to a
320 read-write mounted image to be committed as a new image rather than as
321 an update of the mounted image. (The corresponding new library flag is
322 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
324 The LZMS ("recovery") compression chunk size, or "dictionary size", may
325 now be up to 1 GiB (1,073,741,824 bytes).
327 The performance of LZX ("maximum") and LZMS ("recovery") compression
328 with large chunk sizes has been slightly improved.
331 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
332 decompressed correctly.
334 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
335 occurred in an unlikely case, and due to validity checks it did not
336 affect successfully created archives.
338 Fixed a minor compatibility issue with the LZMS compressor and
339 decompressor. This is *not* the default compression type and was only
340 introduced in v1.6.0. In the unlikely event that you created an
341 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
342 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
345 Memory usage for LZMS and LZX compression has been decreased.
347 wimextract now allows wildcard characters in paths specified on the
348 command line. Also, the '--strict-wildcards' option has been removed
349 and replaced with the inverse option '--nullglob'. See the
350 documentation for wimextract for more details and changes.
352 The wimlib_extract_files() function is now considered deprecated in
353 favor of wimlib_extract_paths().
355 Fixed more permissions problems when extracting files on Windows.
357 A new '--no-attributes' option has been added to wimapply and
358 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
360 The default chunk size is now set correctly when changing the
361 compression type of a WIM, for example with 'wimoptimize'.
363 The '--metadata' option to wiminfo has been replaced with the
364 '--detailed' option to wimdir.
366 In relevant wimlib-imagex commands, '--solid' may now be used as an
367 alias for '--pack-streams'.
370 Support for extracting and updating the new version 3584 WIMs has been
371 added. These WIMs typically pack many streams ("files") together into a
372 single compressed resource, thereby saving space. This degrades the
373 performance of random access (such as that which occurs on a mounted
374 image), but optimizations have been implemented for extraction. These
375 new WIM files also typically use a new compression format (LZMS), which
376 is similar to LZMA and can offer a better compression ratio than LZX.
377 These new WIM files can be created using `wimcapture' with
378 the '--compress=lzms --pack-streams' options. Note: this new WIM format
379 is used by the Windows 8 web downloader, but important segments of the
380 raw '.esd' files are encrypted, so wimlib will not be able to extract
381 such files until they are first decrypted.
383 wimlib now supports extracting files and directories from a WIM image
384 based on a "listfile" that itself contains the list of paths to extract.
385 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
386 and for the library itself, the new APIs are wimlib_extract_pathlist()
387 and wimlib_extract_paths(). Path globs containing wildcard characters
390 For searching WIM files, wimlib now has configurable case sensitivity.
391 The default on Windows is still case-insensitive and the default on
392 UNIX-like systems is still case-sensitive, but this can be overridden
393 on either platform through flags to wimlib_global_init(). For
394 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
395 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
398 Support for compression chunk sizes greater than the default of 32768
399 bytes has been added. A larger chunk size typically results in a better
400 compression ratio. However, the MS implementation is seemingly not
401 compatible with all chunk sizes, especially for LZX compression, so the
402 defaults remain unchanged, with the exception of the new LZMS-compressed
403 WIMs, which use a larger chunk size by default.
405 The compression/decompression API exported by wimlib has been changed.
406 Now one set of functions handles all supported compression formats.
408 `wimcapture' and `wimappend' will now display the progress of scanning
409 the directory tree to capture, in addition to the progress of writing
410 data to the WIM. The '--verbose' option no longer does anything. The
411 library API change for this is the addition of several members to
412 `struct wimlib_progress_info_scan' available to progress callbacks.
414 `mkwinpeimg' now correctly handles the '--start-script' option when the
415 start script is not in the working directory.
417 Sequential extraction, previously requested by using
418 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
419 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
420 behavior (extract in file order).
423 The new LZX compressor added in v1.5.2 has been improved and is now
424 enabled by default, except when `wimcapture' or `wimappend' is run
425 *without* the '--compress' option, in which case the faster LZX
426 compressor is used (the same as before). This behavior is reasonably
427 consistent with ImageX which actually uses "fast" (XPRESS) compression
428 by default. In those cases, use '--compress=maximum' to explicitly
429 capture a WIM image using the new (slower but better) LZX compressor.
431 The '--compress-slow' option still exists to `wimlib-imagex optimize',
432 but its new behavior is to tweak the new LZX compressor even more to
433 produce an even better compression ratio at the cost of more time spent
436 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
437 which recompresses the WIM file using the specified compression TYPE.
438 The new library API function used for this is
439 wimlib_set_output_compression_type().
441 Added the wimlib_get_xml_data() function to allow library clients to
442 easily retrieve the raw XML data from a WIM file if needed.
444 Fixed a bug that could cause an error code to be incorrectly returned
445 when writing XML data containing a <WINDOWS> element.
447 Mounted WIM images will now correctly show the default file stream even
448 if appears in the alternate data stream entries of the corresponding WIM
452 Added a new experimental LZX compressor which can be enabled by passing
453 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
454 optimize'. (The latter is only applicable if the WIM is already
455 LZX-compressed and the '--recompress' option is also given.) The
456 experimental compressor is much slower but compresses the data slightly
457 more --- currently usually to within a fraction of a percent of the
458 results from WIMGAPI/ImageX.
460 A workaround has been added for compatibility with versions of WinPE
461 that interpret alternate data stream entries in the boot WIM
464 An alignment bug that caused a crash in the LZX decompressor on some
467 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
468 the WIM header when restoring the previous state of a WIM it failed to
471 Added a workaround to avoid an access denied error on Windows when
472 replacing a WIM file that another process has opened.
475 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
476 needed to be handled.
478 A bug in the interpretation of negative IMAGE indices in the
479 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
480 `wimlib-imagex append' has been fixed.
482 A workaround has been added to successfully apply security descriptors
483 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
484 2013.1.13 or earlier.
486 `wimlib-imagex capture' can now accept the '--delta-from' option
490 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
491 to standard output and applying images from standard input, but they are
492 not compatible with Microsoft's software and are not created by default.
493 See the documentation for --pipable flag of `wimlib-imagex capture' for
496 To better support incremental backups, added support for declaring an
497 image as a modified form of another image. See the documentation for
498 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
501 Added supported for "delta" WIMs. See the documentation for the
502 '--delta-from' option of `wimlib-imagex capture'.
504 The library support for managing split WIMs has been changed to support
505 other arrangements, such as delta WIMs, and be easier to use. This
506 change is visible in `wimlib-imagex', which also can now accept the
507 '--ref' option multiple times, and also now supports "delta" WIMs as
510 wimlib now preserves WIM integrity tables by default, even if
511 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
512 behavior of `wimlib-imagex' whenever the WIM being operated on contains
513 an integrity table and the '--check' option is not specified.
515 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
516 (when --compress is not specified). This provides the best compression
517 ratio by default, which is usually what is desired, at a cost of some
520 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
521 is the command as in `wimlib-imagex COMMAND'; for example, it can be
522 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
523 appropriate hard links are created in UNIX installations of
524 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
525 batch files that emulate this behavior are generated.
527 Security descriptors are now extracted correctly on Windows.
529 Fixed archiving DOS names in NTFS-3g capture mode.
531 The extraction code has been rewritten and it will now be easier to
532 support new features on all supported backends (currently Win32, UNIX,
533 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
534 now supported on all backends, not just UNIX.
536 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
537 than the WAIK itself.
539 wimlib_global_init() now, by default, attempts to acquire additional
540 privileges on Windows, so library clients need not do this.
542 This update bumps the shared library version number up to 9, since it is
543 not binary compatibible with previous releases.
546 Fixed bug in `wimlib-imagex export' that made it impossible to export an
547 image from a WIM that is readonly at the filesystem level.
549 Return error code rather than segfaulting when trying to list files from
550 a non-first part of a split WIM.
552 Joining a WIM will now preserve the RP_FIX and READONLY flags.
555 On Windows, paths given to wimlib-imagex are now treated case
558 Improved behavior regarding invalid filenames; in particular, on
559 Windows, wimlib-imagex will, when extracting, now omit (with an option
560 to override this default) filenames differing only in case, or filenames
561 containing characters not valid on Windows.
563 On Windows, wimlib now supports capturing and extracting long paths
564 (longer than the so-called MAX_PATH).
566 On Windows, `wimlib-imagex update' now acquires proper privileges when
567 running as an Administrator.
569 `wimlib-imagex update' will now complain if no image is specified when
570 trying to update a multi-image WIM.
572 `wimlib-imagex update' now supports specifying a single update command
573 directly on the command line using the --command option.
575 wimlib-imagex will now choose different units for progress messages,
576 depending on the amount of data that needs to be processed.
578 `wimlib-imagex append' will now generate a unique WIM image name if no
579 name is specified and the defaulted name already exists in the WIM.
581 wimlib now allows you to create unnamed WIM images, which can then only
582 be referred to by index.
584 wimlib now allows you to explicitly declare you want write access to a
585 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
588 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
591 Progress callbacks have been added to wimlib's wimlib_update_image()
594 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
595 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
598 NTFS-3g capture now only warns about two conditions previously treated
601 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
604 wimlib now correctly detects and returns an error when reading a WIM
605 image with a cyclic directory structure. (Fun fact: such a WIM will
606 crash Microsoft's software.)
609 Added new "extract" and "update" subcommands to wimlib-imagex, along
610 with associated APIs in the library. These commands are intended mainly
611 for Windows use but can be used on UNIX as well.
613 Many documentation improvements.
615 Fixed a bug in the Windows build where relative symbolic links were not
616 captured in reparse-point fixup mode.
618 Fixed a bug in the Windows build where file handles were left open to
619 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
621 Fixed a bug in the Windows build of wimlib-imagex where globbing
622 split-WIM parts could cause the program to crash.
624 Fixed a bug where the creation time of WIM images would be shown instead
625 of the last modification time.
627 With the Windows build it is now possible to restore a WIM containing
628 symbolic links as a non-Administrator; however you will receive warnings
629 about not being able to extract the symbolic links.
632 Capturing a WIM image should now be significantly faster in most cases
633 due to improved use of the operating system's cache and avoiding reading
634 files twice whenever possible.
636 The Windows build should now work on Windows XP.
638 The Windows build now supports capturing and restoring hidden,
639 compressed, sparse, and encrypted files.
641 The Windows build now supports capturing and applying WIM images from
642 filesystems other than NTFS (with some reduced functionality).
644 The Windows build now extracts short names correctly.
646 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
647 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
648 capture' and `wimlib-imagex apply'.
650 The performance of splitting and joining WIMs should be slightly
653 The LZX and XPRESS compression and decompression functions are now
654 exported from the library.
657 Improvements and bugfixes for the Windows build.
659 Added --strict-acls options.
661 Fixed the way that wimlib determines the order of images in the WIM.
664 Since wimlib can now be used on Windows, wimlib's implementation of
665 ImageX has been renamed to wimlib-imagex to avoid confusion with
666 Microsoft's implementation of ImageX, which would have the same file
667 name ("imagex.exe"). If you really don't like this you can pass the
668 --with-imagex-progname option to `configure' to choose a different name,
669 or even simply rename the binary yourself (but the former way will
670 configure the man pages to use the chosen name).
672 Various bugs fixed in the Windows build. Mainly to do with capturing
673 and restoring alternate data streams correctly in weird cases, and
674 requesting the correct privileges when opening files. Also added the
675 --noacls options to wimlib-imagex capture, append, and apply.
677 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
678 dynamically loaded, so this may make the library compatible with Windows
679 XP (however, there may still be other problems).
682 Added experimental support for native Windows builds. Binaries can be
683 downloaded from the SourceForge page.
685 --source-list option added to `imagex capture' and `imagex append'.
687 Better support for different character encodings.
690 Storing UNIX file owners, groups, and modes in WIM images is now
691 possible using `imagex capture' with the --unix-data flag.
693 Minor bug fixes and documentation fixes.
696 NTFS capture: Fixed capturing duplicate reparse points.
698 NTFS capture: Capture first unnamed stream if there are more than one
699 (print warning instead of error).
701 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
704 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
707 Update to work with ntfs-3g version 2013.1.13.
710 Fixed truncating file to shorter but non-zero length on read-write
713 Various code cleanups and minor documentation fixes.
716 LZX and XPRESS decompression have received some additional optimizations
717 and should now be even faster. (Although, they were already pretty
718 fast--- much faster than typical I/O speeds.)
720 Fixed a bug introduced in v1.2.1 that would cause a directory tree
721 containing hard links to be captured incorrectly in some cases.
724 By default, unmounting a read-write mounted WIM with 'imagex unmount
725 --commit' will now change the WIM in-place without needing to write the
726 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
729 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
730 for a response from the daemon servicing the mounted WIM. Instead,
731 every second 'imagex unmount' will check if the daemon is still alive,
732 and keep waiting if so, otherwise terminate with an error.
734 'imagex unmount --commit' on a read-write mounted WIM will now print
735 progress information regarding the writing of new or modified streams
736 the WIM, just like when capturing or appending a WIM.
738 A small change has been made to XPRESS compression and it should improve
739 the compression ratio slightly.
741 A change was made that may improve performance slightly when applying a
742 WIM image to a NTFS volume.
744 Microsoft has managed to introduce even more bugs into their software,
745 and now the WIMs for Windows 8 have incorrect (too low) reference counts
746 for some streams. This is unsafe because such streams can be removed
747 when they are in actuality still referenced in the WIM (perhaps by a
748 different image). wimlib will now work around this problem by fixing
749 the stream reference counts. This is only done when wimlib_delete_image() is
750 called ('imagex delete') or when wimlib_mount_image() is called with
751 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
752 requires reading the metadata for all images in the WIM, so this will
753 make these operations noticably slower on WIMs with multiple images.
755 Various other bugfixes.
758 Appending images to a WIM is now be done by default without re-building
759 the whole WIM. Use the --rebuild flag to get the old behavior (which
760 was to re-build the entire WIM when a new image is appended).
762 A new command `imagex optimize' is now available to manually re-build a
763 WIM that has wasted space due to repeated appends.
765 Progress information has been improved, and now arbitrary callback
766 functions can be used to show the progress of a WIM operation.
768 A possible bug with changing the bootable image of a WIM was fixed.
770 Some advisory locking is now done to prevent two processes from
771 modifying a WIM at the same time (but only in some cases). For example,
772 you cannot mount two images from a WIM read-write at the same time.
774 Some functions have been reorganized:
775 * wimlib_mount() renamed to wimlib_mount_image().
776 * wimlib_unmount() renamed to wimlib_unmount_image().
777 * wimlib_overwrite_xml_and_header() removed as
778 wimlib_overwrite() suffices now.
779 * wimlib_apply_image_to_ntfs_volume() removed as
780 wimlib_extract_image() suffices now.
781 * wimlib_add_image_from_ntfs_volume() removed as
782 * wimlib_add_image() suffices now.
784 Previously, the soname of libwim.so has been 0.0.0, despite many
785 interface changes. The soname is now updated to 1.0.0 and will now be
786 updated each release.
789 Resources will now be compressed using multiple threads by default.
790 (This applies to `imagex capture', `imagex append', and `imagex
793 Some performance improvements in mounted WIMs.
795 More progress information is shown when capturing a WIM.
798 Lots of minor fixes, code cleanups, and some documentation updates.
799 Nothing in particular is really noteworthy.
802 LZX and XPRESS compression improvements.
804 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
805 Link Bytes of the WIM.
808 Fixed bug when capturing NTFS file with multiple named data streams.
810 Internally, we are now using inode structures, even though these don't
811 appear literally in the WIM file. This simplifies some of the code
812 (mainly for WIM mounting) and likely fixed a few problems, although it
816 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
820 Enough changes to call it version 1.0.0!
822 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
823 to a NTFS volume, is now supported.
825 Hard links and symbolic links have much improved support. They are
826 supported for WIM capture, WIM application, and mounted WIMs (you can
827 even make them on read-write mounted WIMs).
829 Alternate data streams are now supported on mounted WIMs through an
830 xattr or a Windows-style stream interface. Also they are supported when
831 capturing a WIM from NTFS or applying a WIM to NTFS.
833 Split WIMs are better supported. You may now apply an image directly
834 from a split WIM, mount an image from a split WIM read-only, or export
835 an image from a split WIM.
837 Using a capture configuration file is now supported (but not fully yet).
839 SHA1 message digests are checked in more places, so we can make sure
840 applied and captured data is correct.
842 Man pages have been updated and consolidated.
845 Fixed segfault when unmounting read-only WIM.
848 Support for joining and splitting WIMs.
849 Also, security data is now preserved by default.
852 Can now build with older gcc and system headers, like on CentOS 5.
855 Fixed bug that made it impossible to overwrite files in read-write
859 Write byte-order mark before WIM XML data. (imagex.exe requires this to
