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 In addition, *experimental* support has been added for compressing
25 extracted files using System Compression on Windows 10. This
26 functionality is available through the new '--compact' option to
27 'wimapply' and 'wimextract' as well as new library flags.
30 Fixed a bug in the LZX decompressor: malicious input data could cause
31 out of bounds writes to memory (since wimlib v1.2.2).
33 The output of the 'wiminfo' command now consolidates various boolean
34 flags (such as "Relative path junction") into a single line.
36 A file can now have both an unnamed data stream ("file contents") and a
37 reparse point stream. Such files can exist as a result of the use of
38 certain Windows features, such as offline storage, including "OneDrive".
39 wimlib will now store and restore both streams on Windows as well as in
40 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
42 On Windows, named data streams of encrypted files are no longer stored
43 twice in WIM archives.
45 On Windows, named data streams are now correctly extracted to existing
46 "readonly" directories. Before, an error would be reported.
48 On Windows, it is now possible to do a "WIMBoot mode" extraction with
49 non-standalone WIMs such as delta WIMs.
51 On Windows, when doing an extraction in "WIMBoot mode", files larger
52 than 4 gigabytes are now never extracted as externally backed. This
53 works around a bug in Microsoft's "WOF" driver.
55 The '--enable-verify-compression' configure option has been removed. If
56 you want to verify a WIM file, use the 'wimverify' program.
58 The way the "file count", "directory count", "total bytes", and "hard
59 link bytes" image statistics (stored in the WIM XML data) is calculated
60 has been slightly changed.
62 In mounted WIM images, the disk usage provided for each file (st_blocks)
63 is now the compressed size rather than the uncompressed size.
65 The performance of the NTFS-3g and Windows capture modes has been
68 On UNIX-like systems, symbolic links whose targets contain the backslash
69 character are now handled correctly (losslessly).
72 Improved the LZX compressor. It is now 15-20% faster than before and
73 provides a slightly better compression ratio.
75 Improved the LZMS compressor. It now provides a compression ratio
76 slightly better than WIMGAPI while still being faster and using slightly
79 The compression chunk size in solid resources, e.g. when capturing or
80 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
81 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
82 better compression ratio and is the same value that WIMGAPI uses. The
83 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
84 lower than WIMGAPI's memory usage, but if it is too much, it is still
85 possible to choose a lower value, e.g. with the '--solid-chunk-size'
86 option to wimlib-imagex.
88 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
89 accept the 'K', 'M', and 'G' suffixes.
91 Files are now sorted by name extension when creating a solid WIM file.
93 Fixed various issues related to capture/apply of EFS-encrypted files on
96 The file list printed by 'wimdir' is now sorted by the platform-specific
97 case sensitivity setting, rather than always case sensitively. This
98 also affects the library function wimlib_iterate_dir_tree().
100 On Windows, some error and warning messages have been improved.
103 The Windows binary distribution no longer contains third party DLLs.
104 These dependencies are instead compiled directly into the libwim DLL.
106 Added more fixes for wimlib on non-x86 architectures such as ARM.
108 Extracting files to a Windows PE in-memory filesystem no longer fails if
109 the target files do not yet exist.
111 Improved the performance of XPRESS compression and LZMS decompression.
113 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
114 It will automatically be faster on newer Intel and AMD processors.
116 Removed the --with-imagex-progname and --enable-more-assertions
120 Fix for very slow export from solid WIM / ESD files.
122 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
124 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
125 may use this to treat some types of errors as non-fatal.
127 The library now permits making in-memory changes to a WIMStruct backed
128 by a read-only WIM file.
130 Fixes for "WIMBoot" extraction mode (Windows only):
132 When not using the WOF driver, extraction no longer fails if the
133 disk containing the WIM file has too many partitions.
135 When matching patterns in [PrepopulateList], all hard links of
136 each file are now considered.
138 The system registry files are now automatically treated as being
139 in [PrepopulateList].
141 Added a hack to try to work around an intermittent bug in
142 Microsoft's WOF (Windows Overlay Filesystem) driver.
145 Made more improvements to the XPRESS, LZX, and LZMS compressors.
147 A number of improvements to the Windows port:
149 Fixes for setting short filenames.
151 Faster "WIMBoot" extraction.
153 Updated and slimmed down the dependent DLLs.
155 ACL inheritence bits are now restored.
157 Mandatory integrity labels are now backed up and restored.
159 Added a workaround for an issue where in rare cases, wimlib could create
160 a compressed data stream that could not be read correctly by Windows
161 after an extraction in "WIMBoot" mode.
164 Added file count progress data for
165 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
166 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
168 Added support for testing file exclusions via the user-provided
171 Some documentation improvements.
173 Made some clarifications to the license text in the COPYING file.
176 Made more improvements to the XPRESS, LZX, and LZMS compressors.
178 The default compression mode for wimcapture is now LZX compression in
179 its default mode, which is the same as '--compress=maximum'.
181 You can now specify an optional integer compression level to the
182 '--compress' option; e.g. '--compress=lzx:75'.
184 Made a minor change to the LZMS compressor and decompressor to fix an
185 incompatibility with the Microsoft implementation. In the unlikely
186 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
187 earlier and a checksum error is reported when extracting files from it
188 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
191 Added 'verify' subcommand to wimlib-imagex.
193 Notable library changes:
195 Custom compressor parameters have been removed from the library
196 in favor of the simpler level-based API.
198 Decompressor parameters have been removed entirely.
200 Library users can now specify a custom file for warning and
201 error messages to be sent to, rather than the default of
204 New progress messages:
205 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
206 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
208 New function: wimlib_verify_wim().
211 Improved compression, decompression, and extraction performance.
213 Improved compatibility with version 3584 WIM / ESD files:
214 - Add support for reading and writing multiple solid blocks per
215 archive, which WIMGAPI/DISM can create when appending an image.
216 - Correctly create solid blocks larger than 4 GiB.
218 'add' commands passed to wimupdate will now replace existing
219 nondirectory files by default. Use the --no-replace option to get the
222 The license for the library now contains an exception that allows using
223 it under the LGPL. See the COPYING file for details.
225 In reparse-point fixup mode (the default for capture), symbolic links
226 and junctions that point outside the tree being captured are no longer
227 excluded from capture.
229 Added support for "WIMBoot" capture and extraction. See the
230 documentation for the new '--wimboot' option to wimcapture and wimapply
231 for more information.
233 On UNIX-like systems, you can now backup and restore device nodes, named
234 pipes, and sockets. In addition, 32-bit user and group IDs are now
237 The way that UNIX data is stored in WIM files has been changed. If you
238 captured any WIMs with the --unix-data option, to upgrade them you'll
239 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
240 re-capture them with --unix-data using this version.
242 wimlib now understands tagged metadata items, such as object IDs, that
243 can be stored in WIM directory entries.
245 Removed the --hardlink and --symlink options to wimapply, since I don't
246 think they are too useful and they got in the way of improving the code.
248 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
250 The 'mkwinpeimg' script now supports writing the ISO image to standard
253 The <ARCH> element in WIM XML data is now exported correctly.
255 On Windows, sparse file attributes are no longer set on extracted files.
256 Oddly enough, this actually saves disk space in some cases.
258 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
259 supported. Mounting WIM images now always requires extended attribute
260 support. Use --without-fuse to disable support for mounting WIM images;
261 this will also disable the need for extended attribute support.
263 Configuring with --enable-ssse3-sha1 now works correctly.
265 The shared library version has been bumped up. The main
266 incompatibilities are:
268 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
269 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
272 - User-provided progress functions are now registered using a
273 separate function, wimlib_register_progress_function(). The
274 'progress_func' argument to many functions no longer exists.
276 - The return value from user-provided progress functions is now
279 - A context argument has been added to the prototype of
280 user-provided progress functions.
282 - 'struct wimlib_capture_config' has been removed. The library
283 now takes the path to the configuration file directly. This
284 affects wimlib_add_image(), wimlib_add_image_multisource(),
285 and wimlib_update_image(). However, a NULL value passed in
286 the argument retains the same meaning.
288 - Removed deprecated functions: some (de)compression functions,
289 wimlib_extract_files(), and wimlib_print_metadata().
291 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
292 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
293 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
295 - Removed some progress messages:
296 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
297 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
298 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
301 - Removed some error codes. Numbering stays the same.
303 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
304 WIMLIB_UNMOUNT_FLAG_FORCE.
306 - WIM paths passed to progress functions now have a leading
310 Case-insensitive comparisons of strings (e.g. filenames) containing
311 UTF-16 codepoints above 32767 are now done correctly.
313 Fixed build failure on Mac OS X.
315 wimunmount now provides the '--new-image' option to cause changes to a
316 read-write mounted image to be committed as a new image rather than as
317 an update of the mounted image. (The corresponding new library flag is
318 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
320 The LZMS ("recovery") compression chunk size, or "dictionary size", may
321 now be up to 1 GiB (1,073,741,824 bytes).
323 The performance of LZX ("maximum") and LZMS ("recovery") compression
324 with large chunk sizes has been slightly improved.
327 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
328 decompressed correctly.
330 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
331 occurred in an unlikely case, and due to validity checks it did not
332 affect successfully created archives.
334 Fixed a minor compatibility issue with the LZMS compressor and
335 decompressor. This is *not* the default compression type and was only
336 introduced in v1.6.0. In the unlikely event that you created an
337 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
338 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
341 Memory usage for LZMS and LZX compression has been decreased.
343 wimextract now allows wildcard characters in paths specified on the
344 command line. Also, the '--strict-wildcards' option has been removed
345 and replaced with the inverse option '--nullglob'. See the
346 documentation for wimextract for more details and changes.
348 The wimlib_extract_files() function is now considered deprecated in
349 favor of wimlib_extract_paths().
351 Fixed more permissions problems when extracting files on Windows.
353 A new '--no-attributes' option has been added to wimapply and
354 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
356 The default chunk size is now set correctly when changing the
357 compression type of a WIM, for example with 'wimoptimize'.
359 The '--metadata' option to wiminfo has been replaced with the
360 '--detailed' option to wimdir.
362 In relevant wimlib-imagex commands, '--solid' may now be used as an
363 alias for '--pack-streams'.
366 Support for extracting and updating the new version 3584 WIMs has been
367 added. These WIMs typically pack many streams ("files") together into a
368 single compressed resource, thereby saving space. This degrades the
369 performance of random access (such as that which occurs on a mounted
370 image), but optimizations have been implemented for extraction. These
371 new WIM files also typically use a new compression format (LZMS), which
372 is similar to LZMA and can offer a better compression ratio than LZX.
373 These new WIM files can be created using `wimcapture' with
374 the '--compress=lzms --pack-streams' options. Note: this new WIM format
375 is used by the Windows 8 web downloader, but important segments of the
376 raw '.esd' files are encrypted, so wimlib will not be able to extract
377 such files until they are first decrypted.
379 wimlib now supports extracting files and directories from a WIM image
380 based on a "listfile" that itself contains the list of paths to extract.
381 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
382 and for the library itself, the new APIs are wimlib_extract_pathlist()
383 and wimlib_extract_paths(). Path globs containing wildcard characters
386 For searching WIM files, wimlib now has configurable case sensitivity.
387 The default on Windows is still case-insensitive and the default on
388 UNIX-like systems is still case-sensitive, but this can be overridden
389 on either platform through flags to wimlib_global_init(). For
390 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
391 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
394 Support for compression chunk sizes greater than the default of 32768
395 bytes has been added. A larger chunk size typically results in a better
396 compression ratio. However, the MS implementation is seemingly not
397 compatible with all chunk sizes, especially for LZX compression, so the
398 defaults remain unchanged, with the exception of the new LZMS-compressed
399 WIMs, which use a larger chunk size by default.
401 The compression/decompression API exported by wimlib has been changed.
402 Now one set of functions handles all supported compression formats.
404 `wimcapture' and `wimappend' will now display the progress of scanning
405 the directory tree to capture, in addition to the progress of writing
406 data to the WIM. The '--verbose' option no longer does anything. The
407 library API change for this is the addition of several members to
408 `struct wimlib_progress_info_scan' available to progress callbacks.
410 `mkwinpeimg' now correctly handles the '--start-script' option when the
411 start script is not in the working directory.
413 Sequential extraction, previously requested by using
414 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
415 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
416 behavior (extract in file order).
419 The new LZX compressor added in v1.5.2 has been improved and is now
420 enabled by default, except when `wimcapture' or `wimappend' is run
421 *without* the '--compress' option, in which case the faster LZX
422 compressor is used (the same as before). This behavior is reasonably
423 consistent with ImageX which actually uses "fast" (XPRESS) compression
424 by default. In those cases, use '--compress=maximum' to explicitly
425 capture a WIM image using the new (slower but better) LZX compressor.
427 The '--compress-slow' option still exists to `wimlib-imagex optimize',
428 but its new behavior is to tweak the new LZX compressor even more to
429 produce an even better compression ratio at the cost of more time spent
432 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
433 which recompresses the WIM file using the specified compression TYPE.
434 The new library API function used for this is
435 wimlib_set_output_compression_type().
437 Added the wimlib_get_xml_data() function to allow library clients to
438 easily retrieve the raw XML data from a WIM file if needed.
440 Fixed a bug that could cause an error code to be incorrectly returned
441 when writing XML data containing a <WINDOWS> element.
443 Mounted WIM images will now correctly show the default file stream even
444 if appears in the alternate data stream entries of the corresponding WIM
448 Added a new experimental LZX compressor which can be enabled by passing
449 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
450 optimize'. (The latter is only applicable if the WIM is already
451 LZX-compressed and the '--recompress' option is also given.) The
452 experimental compressor is much slower but compresses the data slightly
453 more --- currently usually to within a fraction of a percent of the
454 results from WIMGAPI/ImageX.
456 A workaround has been added for compatibility with versions of WinPE
457 that interpret alternate data stream entries in the boot WIM
460 An alignment bug that caused a crash in the LZX decompressor on some
463 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
464 the WIM header when restoring the previous state of a WIM it failed to
467 Added a workaround to avoid an access denied error on Windows when
468 replacing a WIM file that another process has opened.
471 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
472 needed to be handled.
474 A bug in the interpretation of negative IMAGE indices in the
475 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
476 `wimlib-imagex append' has been fixed.
478 A workaround has been added to successfully apply security descriptors
479 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
480 2013.1.13 or earlier.
482 `wimlib-imagex capture' can now accept the '--delta-from' option
486 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
487 to standard output and applying images from standard input, but they are
488 not compatible with Microsoft's software and are not created by default.
489 See the documentation for --pipable flag of `wimlib-imagex capture' for
492 To better support incremental backups, added support for declaring an
493 image as a modified form of another image. See the documentation for
494 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
497 Added supported for "delta" WIMs. See the documentation for the
498 '--delta-from' option of `wimlib-imagex capture'.
500 The library support for managing split WIMs has been changed to support
501 other arrangements, such as delta WIMs, and be easier to use. This
502 change is visible in `wimlib-imagex', which also can now accept the
503 '--ref' option multiple times, and also now supports "delta" WIMs as
506 wimlib now preserves WIM integrity tables by default, even if
507 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
508 behavior of `wimlib-imagex' whenever the WIM being operated on contains
509 an integrity table and the '--check' option is not specified.
511 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
512 (when --compress is not specified). This provides the best compression
513 ratio by default, which is usually what is desired, at a cost of some
516 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
517 is the command as in `wimlib-imagex COMMAND'; for example, it can be
518 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
519 appropriate hard links are created in UNIX installations of
520 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
521 batch files that emulate this behavior are generated.
523 Security descriptors are now extracted correctly on Windows.
525 Fixed archiving DOS names in NTFS-3g capture mode.
527 The extraction code has been rewritten and it will now be easier to
528 support new features on all supported backends (currently Win32, UNIX,
529 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
530 now supported on all backends, not just UNIX.
532 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
533 than the WAIK itself.
535 wimlib_global_init() now, by default, attempts to acquire additional
536 privileges on Windows, so library clients need not do this.
538 This update bumps the shared library version number up to 9, since it is
539 not binary compatibible with previous releases.
542 Fixed bug in `wimlib-imagex export' that made it impossible to export an
543 image from a WIM that is readonly at the filesystem level.
545 Return error code rather than segfaulting when trying to list files from
546 a non-first part of a split WIM.
548 Joining a WIM will now preserve the RP_FIX and READONLY flags.
551 On Windows, paths given to wimlib-imagex are now treated case
554 Improved behavior regarding invalid filenames; in particular, on
555 Windows, wimlib-imagex will, when extracting, now omit (with an option
556 to override this default) filenames differing only in case, or filenames
557 containing characters not valid on Windows.
559 On Windows, wimlib now supports capturing and extracting long paths
560 (longer than the so-called MAX_PATH).
562 On Windows, `wimlib-imagex update' now acquires proper privileges when
563 running as an Administrator.
565 `wimlib-imagex update' will now complain if no image is specified when
566 trying to update a multi-image WIM.
568 `wimlib-imagex update' now supports specifying a single update command
569 directly on the command line using the --command option.
571 wimlib-imagex will now choose different units for progress messages,
572 depending on the amount of data that needs to be processed.
574 `wimlib-imagex append' will now generate a unique WIM image name if no
575 name is specified and the defaulted name already exists in the WIM.
577 wimlib now allows you to create unnamed WIM images, which can then only
578 be referred to by index.
580 wimlib now allows you to explicitly declare you want write access to a
581 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
584 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
587 Progress callbacks have been added to wimlib's wimlib_update_image()
590 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
591 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
594 NTFS-3g capture now only warns about two conditions previously treated
597 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
600 wimlib now correctly detects and returns an error when reading a WIM
601 image with a cyclic directory structure. (Fun fact: such a WIM will
602 crash Microsoft's software.)
605 Added new "extract" and "update" subcommands to wimlib-imagex, along
606 with associated APIs in the library. These commands are intended mainly
607 for Windows use but can be used on UNIX as well.
609 Many documentation improvements.
611 Fixed a bug in the Windows build where relative symbolic links were not
612 captured in reparse-point fixup mode.
614 Fixed a bug in the Windows build where file handles were left open to
615 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
617 Fixed a bug in the Windows build of wimlib-imagex where globbing
618 split-WIM parts could cause the program to crash.
620 Fixed a bug where the creation time of WIM images would be shown instead
621 of the last modification time.
623 With the Windows build it is now possible to restore a WIM containing
624 symbolic links as a non-Administrator; however you will receive warnings
625 about not being able to extract the symbolic links.
628 Capturing a WIM image should now be significantly faster in most cases
629 due to improved use of the operating system's cache and avoiding reading
630 files twice whenever possible.
632 The Windows build should now work on Windows XP.
634 The Windows build now supports capturing and restoring hidden,
635 compressed, sparse, and encrypted files.
637 The Windows build now supports capturing and applying WIM images from
638 filesystems other than NTFS (with some reduced functionality).
640 The Windows build now extracts short names correctly.
642 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
643 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
644 capture' and `wimlib-imagex apply'.
646 The performance of splitting and joining WIMs should be slightly
649 The LZX and XPRESS compression and decompression functions are now
650 exported from the library.
653 Improvements and bugfixes for the Windows build.
655 Added --strict-acls options.
657 Fixed the way that wimlib determines the order of images in the WIM.
660 Since wimlib can now be used on Windows, wimlib's implementation of
661 ImageX has been renamed to wimlib-imagex to avoid confusion with
662 Microsoft's implementation of ImageX, which would have the same file
663 name ("imagex.exe"). If you really don't like this you can pass the
664 --with-imagex-progname option to `configure' to choose a different name,
665 or even simply rename the binary yourself (but the former way will
666 configure the man pages to use the chosen name).
668 Various bugs fixed in the Windows build. Mainly to do with capturing
669 and restoring alternate data streams correctly in weird cases, and
670 requesting the correct privileges when opening files. Also added the
671 --noacls options to wimlib-imagex capture, append, and apply.
673 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
674 dynamically loaded, so this may make the library compatible with Windows
675 XP (however, there may still be other problems).
678 Added experimental support for native Windows builds. Binaries can be
679 downloaded from the SourceForge page.
681 --source-list option added to `imagex capture' and `imagex append'.
683 Better support for different character encodings.
686 Storing UNIX file owners, groups, and modes in WIM images is now
687 possible using `imagex capture' with the --unix-data flag.
689 Minor bug fixes and documentation fixes.
692 NTFS capture: Fixed capturing duplicate reparse points.
694 NTFS capture: Capture first unnamed stream if there are more than one
695 (print warning instead of error).
697 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
700 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
703 Update to work with ntfs-3g version 2013.1.13.
706 Fixed truncating file to shorter but non-zero length on read-write
709 Various code cleanups and minor documentation fixes.
712 LZX and XPRESS decompression have received some additional optimizations
713 and should now be even faster. (Although, they were already pretty
714 fast--- much faster than typical I/O speeds.)
716 Fixed a bug introduced in v1.2.1 that would cause a directory tree
717 containing hard links to be captured incorrectly in some cases.
720 By default, unmounting a read-write mounted WIM with 'imagex unmount
721 --commit' will now change the WIM in-place without needing to write the
722 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
725 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
726 for a response from the daemon servicing the mounted WIM. Instead,
727 every second 'imagex unmount' will check if the daemon is still alive,
728 and keep waiting if so, otherwise terminate with an error.
730 'imagex unmount --commit' on a read-write mounted WIM will now print
731 progress information regarding the writing of new or modified streams
732 the WIM, just like when capturing or appending a WIM.
734 A small change has been made to XPRESS compression and it should improve
735 the compression ratio slightly.
737 A change was made that may improve performance slightly when applying a
738 WIM image to a NTFS volume.
740 Microsoft has managed to introduce even more bugs into their software,
741 and now the WIMs for Windows 8 have incorrect (too low) reference counts
742 for some streams. This is unsafe because such streams can be removed
743 when they are in actuality still referenced in the WIM (perhaps by a
744 different image). wimlib will now work around this problem by fixing
745 the stream reference counts. This is only done when wimlib_delete_image() is
746 called ('imagex delete') or when wimlib_mount_image() is called with
747 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
748 requires reading the metadata for all images in the WIM, so this will
749 make these operations noticably slower on WIMs with multiple images.
751 Various other bugfixes.
754 Appending images to a WIM is now be done by default without re-building
755 the whole WIM. Use the --rebuild flag to get the old behavior (which
756 was to re-build the entire WIM when a new image is appended).
758 A new command `imagex optimize' is now available to manually re-build a
759 WIM that has wasted space due to repeated appends.
761 Progress information has been improved, and now arbitrary callback
762 functions can be used to show the progress of a WIM operation.
764 A possible bug with changing the bootable image of a WIM was fixed.
766 Some advisory locking is now done to prevent two processes from
767 modifying a WIM at the same time (but only in some cases). For example,
768 you cannot mount two images from a WIM read-write at the same time.
770 Some functions have been reorganized:
771 * wimlib_mount() renamed to wimlib_mount_image().
772 * wimlib_unmount() renamed to wimlib_unmount_image().
773 * wimlib_overwrite_xml_and_header() removed as
774 wimlib_overwrite() suffices now.
775 * wimlib_apply_image_to_ntfs_volume() removed as
776 wimlib_extract_image() suffices now.
777 * wimlib_add_image_from_ntfs_volume() removed as
778 * wimlib_add_image() suffices now.
780 Previously, the soname of libwim.so has been 0.0.0, despite many
781 interface changes. The soname is now updated to 1.0.0 and will now be
782 updated each release.
785 Resources will now be compressed using multiple threads by default.
786 (This applies to `imagex capture', `imagex append', and `imagex
789 Some performance improvements in mounted WIMs.
791 More progress information is shown when capturing a WIM.
794 Lots of minor fixes, code cleanups, and some documentation updates.
795 Nothing in particular is really noteworthy.
798 LZX and XPRESS compression improvements.
800 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
801 Link Bytes of the WIM.
804 Fixed bug when capturing NTFS file with multiple named data streams.
806 Internally, we are now using inode structures, even though these don't
807 appear literally in the WIM file. This simplifies some of the code
808 (mainly for WIM mounting) and likely fixed a few problems, although it
812 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
816 Enough changes to call it version 1.0.0!
818 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
819 to a NTFS volume, is now supported.
821 Hard links and symbolic links have much improved support. They are
822 supported for WIM capture, WIM application, and mounted WIMs (you can
823 even make them on read-write mounted WIMs).
825 Alternate data streams are now supported on mounted WIMs through an
826 xattr or a Windows-style stream interface. Also they are supported when
827 capturing a WIM from NTFS or applying a WIM to NTFS.
829 Split WIMs are better supported. You may now apply an image directly
830 from a split WIM, mount an image from a split WIM read-only, or export
831 an image from a split WIM.
833 Using a capture configuration file is now supported (but not fully yet).
835 SHA1 message digests are checked in more places, so we can make sure
836 applied and captured data is correct.
838 Man pages have been updated and consolidated.
841 Fixed segfault when unmounting read-only WIM.
844 Support for joining and splitting WIMs.
845 Also, security data is now preserved by default.
848 Can now build with older gcc and system headers, like on CentOS 5.
851 Fixed bug that made it impossible to overwrite files in read-write
855 Write byte-order mark before WIM XML data. (imagex.exe requires this to
