2 Fixed a bug in the LZX decompressor: malicious input data could cause
3 out of bounds writes to memory (since wimlib v1.2.2).
5 The output of the 'wiminfo' command now consolidates various boolean
6 flags (such as "Relative path junction") into a single line.
8 A file can now have both an unnamed data stream ("file contents") and a
9 reparse point stream. Such files can exist as a result of the use of
10 certain Windows features, such as offline storage, including "OneDrive".
11 wimlib will now store and restore both streams on Windows as well as in
12 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
14 On Windows, named data streams of encrypted files are no longer stored
15 twice in WIM archives.
17 On Windows, named data streams are now correctly extracted to existing
18 "readonly" directories. Before, an error would be reported.
20 On Windows, when doing an extraction in "WIMBoot mode", files larger
21 than 4 gigabytes are now never extracted as externally backed. This
22 works around a bug in Microsoft's "WOF" driver.
24 The '--enable-verify-compression' configure option has been removed. If
25 you want to verify a WIM file, use the 'wimverify' program.
27 The way the "file count", "directory count", "total bytes", and "hard
28 link bytes" image statistics (stored in the WIM XML data) is calculated
29 has been slightly changed.
31 In mounted WIM images, the disk usage provided for each file (st_blocks)
32 is now the compressed size rather than the uncompressed size.
34 The performance of the NTFS-3g and Windows capture modes has been
37 On UNIX-like systems, symbolic links whose targets contain the backslash
38 character are now handled correctly (losslessly).
41 Improved the LZX compressor. It is now 15-20% faster than before and
42 provides a slightly better compression ratio.
44 Improved the LZMS compressor. It now provides a compression ratio
45 slightly better than WIMGAPI while still being faster and using slightly
48 The compression chunk size in solid resources, e.g. when capturing or
49 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
50 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
51 better compression ratio and is the same value that WIMGAPI uses. The
52 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
53 lower than WIMGAPI's memory usage, but if it is too much, it is still
54 possible to choose a lower value, e.g. with the '--solid-chunk-size'
55 option to wimlib-imagex.
57 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
58 accept the 'K', 'M', and 'G' suffixes.
60 Files are now sorted by name extension when creating a solid WIM file.
62 Fixed various issues related to capture/apply of EFS-encrypted files on
65 The file list printed by 'wimdir' is now sorted by the platform-specific
66 case sensitivity setting, rather than always case sensitively. This
67 also affects the library function wimlib_iterate_dir_tree().
69 On Windows, some error and warning messages have been improved.
72 The Windows binary distribution no longer contains third party DLLs.
73 These dependencies are instead compiled directly into the libwim DLL.
75 Added more fixes for wimlib on non-x86 architectures such as ARM.
77 Extracting files to a Windows PE in-memory filesystem no longer fails if
78 the target files do not yet exist.
80 Improved the performance of XPRESS compression and LZMS decompression.
82 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
83 It will automatically be faster on newer Intel and AMD processors.
85 Removed the --with-imagex-progname and --enable-more-assertions
89 Fix for very slow export from solid WIM / ESD files.
91 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
93 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
94 may use this to treat some types of errors as non-fatal.
96 The library now permits making in-memory changes to a WIMStruct backed
97 by a read-only WIM file.
99 Fixes for "WIMBoot" extraction mode (Windows only):
101 When not using the WOF driver, extraction no longer fails if the
102 disk containing the WIM file has too many partitions.
104 When matching patterns in [PrepopulateList], all hard links of
105 each file are now considered.
107 The system registry files are now automatically treated as being
108 in [PrepopulateList].
110 Added a hack to try to work around an intermittent bug in
111 Microsoft's WOF (Windows Overlay Filesystem) driver.
114 Made more improvements to the XPRESS, LZX, and LZMS compressors.
116 A number of improvements to the Windows port:
118 Fixes for setting short filenames.
120 Faster "WIMBoot" extraction.
122 Updated and slimmed down the dependent DLLs.
124 ACL inheritence bits are now restored.
126 Mandatory integrity labels are now backed up and restored.
128 Added a workaround for an issue where in rare cases, wimlib could create
129 a compressed data stream that could not be read correctly by Windows
130 after an extraction in "WIMBoot" mode.
133 Added file count progress data for
134 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
135 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
137 Added support for testing file exclusions via the user-provided
140 Some documentation improvements.
142 Made some clarifications to the license text in the COPYING file.
145 Made more improvements to the XPRESS, LZX, and LZMS compressors.
147 The default compression mode for wimcapture is now LZX compression in
148 its default mode, which is the same as '--compress=maximum'.
150 You can now specify an optional integer compression level to the
151 '--compress' option; e.g. '--compress=lzx:75'.
153 Made a minor change to the LZMS compressor and decompressor to fix an
154 incompatibility with the Microsoft implementation. In the unlikely
155 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
156 earlier and a checksum error is reported when extracting files from it
157 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
160 Added 'verify' subcommand to wimlib-imagex.
162 Notable library changes:
164 Custom compressor parameters have been removed from the library
165 in favor of the simpler level-based API.
167 Decompressor parameters have been removed entirely.
169 Library users can now specify a custom file for warning and
170 error messages to be sent to, rather than the default of
173 New progress messages:
174 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
175 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
177 New function: wimlib_verify_wim().
180 Improved compression, decompression, and extraction performance.
182 Improved compatibility with version 3584 WIM / ESD files:
183 - Add support for reading and writing multiple solid blocks per
184 archive, which WIMGAPI/DISM can create when appending an image.
185 - Correctly create solid blocks larger than 4 GiB.
187 'add' commands passed to wimupdate will now replace existing
188 nondirectory files by default. Use the --no-replace option to get the
191 The license for the library now contains an exception that allows using
192 it under the LGPL. See the COPYING file for details.
194 In reparse-point fixup mode (the default for capture), symbolic links
195 and junctions that point outside the tree being captured are no longer
196 excluded from capture.
198 Added support for "WIMBoot" capture and extraction. See the
199 documentation for the new '--wimboot' option to wimcapture and wimapply
200 for more information.
202 On UNIX-like systems, you can now backup and restore device nodes, named
203 pipes, and sockets. In addition, 32-bit user and group IDs are now
206 The way that UNIX data is stored in WIM files has been changed. If you
207 captured any WIMs with the --unix-data option, to upgrade them you'll
208 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
209 re-capture them with --unix-data using this version.
211 wimlib now understands tagged metadata items, such as object IDs, that
212 can be stored in WIM directory entries.
214 Removed the --hardlink and --symlink options to wimapply, since I don't
215 think they are too useful and they got in the way of improving the code.
217 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
219 The 'mkwinpeimg' script now supports writing the ISO image to standard
222 The <ARCH> element in WIM XML data is now exported correctly.
224 On Windows, sparse file attributes are no longer set on extracted files.
225 Oddly enough, this actually saves disk space in some cases.
227 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
228 supported. Mounting WIM images now always requires extended attribute
229 support. Use --without-fuse to disable support for mounting WIM images;
230 this will also disable the need for extended attribute support.
232 Configuring with --enable-ssse3-sha1 now works correctly.
234 The shared library version has been bumped up. The main
235 incompatibilities are:
237 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
238 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
241 - User-provided progress functions are now registered using a
242 separate function, wimlib_register_progress_function(). The
243 'progress_func' argument to many functions no longer exists.
245 - The return value from user-provided progress functions is now
248 - A context argument has been added to the prototype of
249 user-provided progress functions.
251 - 'struct wimlib_capture_config' has been removed. The library
252 now takes the path to the configuration file directly. This
253 affects wimlib_add_image(), wimlib_add_image_multisource(),
254 and wimlib_update_image(). However, a NULL value passed in
255 the argument retains the same meaning.
257 - Removed deprecated functions: some (de)compression functions,
258 wimlib_extract_files(), and wimlib_print_metadata().
260 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
261 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
262 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
264 - Removed some progress messages:
265 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
266 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
267 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
270 - Removed some error codes. Numbering stays the same.
272 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
273 WIMLIB_UNMOUNT_FLAG_FORCE.
275 - WIM paths passed to progress functions now have a leading
279 Case-insensitive comparisons of strings (e.g. filenames) containing
280 UTF-16 codepoints above 32767 are now done correctly.
282 Fixed build failure on Mac OS X.
284 wimunmount now provides the '--new-image' option to cause changes to a
285 read-write mounted image to be committed as a new image rather than as
286 an update of the mounted image. (The corresponding new library flag is
287 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
289 The LZMS ("recovery") compression chunk size, or "dictionary size", may
290 now be up to 1 GiB (1,073,741,824 bytes).
292 The performance of LZX ("maximum") and LZMS ("recovery") compression
293 with large chunk sizes has been slightly improved.
296 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
297 decompressed correctly.
299 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
300 occurred in an unlikely case, and due to validity checks it did not
301 affect successfully created archives.
303 Fixed a minor compatibility issue with the LZMS compressor and
304 decompressor. This is *not* the default compression type and was only
305 introduced in v1.6.0. In the unlikely event that you created an
306 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
307 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
310 Memory usage for LZMS and LZX compression has been decreased.
312 wimextract now allows wildcard characters in paths specified on the
313 command line. Also, the '--strict-wildcards' option has been removed
314 and replaced with the inverse option '--nullglob'. See the
315 documentation for wimextract for more details and changes.
317 The wimlib_extract_files() function is now considered deprecated in
318 favor of wimlib_extract_paths().
320 Fixed more permissions problems when extracting files on Windows.
322 A new '--no-attributes' option has been added to wimapply and
323 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
325 The default chunk size is now set correctly when changing the
326 compression type of a WIM, for example with 'wimoptimize'.
328 The '--metadata' option to wiminfo has been replaced with the
329 '--detailed' option to wimdir.
331 In relevant wimlib-imagex commands, '--solid' may now be used as an
332 alias for '--pack-streams'.
335 Support for extracting and updating the new version 3584 WIMs has been
336 added. These WIMs typically pack many streams ("files") together into a
337 single compressed resource, thereby saving space. This degrades the
338 performance of random access (such as that which occurs on a mounted
339 image), but optimizations have been implemented for extraction. These
340 new WIM files also typically use a new compression format (LZMS), which
341 is similar to LZMA and can offer a better compression ratio than LZX.
342 These new WIM files can be created using `wimcapture' with
343 the '--compress=lzms --pack-streams' options. Note: this new WIM format
344 is used by the Windows 8 web downloader, but important segments of the
345 raw '.esd' files are encrypted, so wimlib will not be able to extract
346 such files until they are first decrypted.
348 wimlib now supports extracting files and directories from a WIM image
349 based on a "listfile" that itself contains the list of paths to extract.
350 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
351 and for the library itself, the new APIs are wimlib_extract_pathlist()
352 and wimlib_extract_paths(). Path globs containing wildcard characters
355 For searching WIM files, wimlib now has configurable case sensitivity.
356 The default on Windows is still case-insensitive and the default on
357 UNIX-like systems is still case-sensitive, but this can be overridden
358 on either platform through flags to wimlib_global_init(). For
359 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
360 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
363 Support for compression chunk sizes greater than the default of 32768
364 bytes has been added. A larger chunk size typically results in a better
365 compression ratio. However, the MS implementation is seemingly not
366 compatible with all chunk sizes, especially for LZX compression, so the
367 defaults remain unchanged, with the exception of the new LZMS-compressed
368 WIMs, which use a larger chunk size by default.
370 The compression/decompression API exported by wimlib has been changed.
371 Now one set of functions handles all supported compression formats.
373 `wimcapture' and `wimappend' will now display the progress of scanning
374 the directory tree to capture, in addition to the progress of writing
375 data to the WIM. The '--verbose' option no longer does anything. The
376 library API change for this is the addition of several members to
377 `struct wimlib_progress_info_scan' available to progress callbacks.
379 `mkwinpeimg' now correctly handles the '--start-script' option when the
380 start script is not in the working directory.
382 Sequential extraction, previously requested by using
383 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
384 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
385 behavior (extract in file order).
388 The new LZX compressor added in v1.5.2 has been improved and is now
389 enabled by default, except when `wimcapture' or `wimappend' is run
390 *without* the '--compress' option, in which case the faster LZX
391 compressor is used (the same as before). This behavior is reasonably
392 consistent with ImageX which actually uses "fast" (XPRESS) compression
393 by default. In those cases, use '--compress=maximum' to explicitly
394 capture a WIM image using the new (slower but better) LZX compressor.
396 The '--compress-slow' option still exists to `wimlib-imagex optimize',
397 but its new behavior is to tweak the new LZX compressor even more to
398 produce an even better compression ratio at the cost of more time spent
401 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
402 which recompresses the WIM file using the specified compression TYPE.
403 The new library API function used for this is
404 wimlib_set_output_compression_type().
406 Added the wimlib_get_xml_data() function to allow library clients to
407 easily retrieve the raw XML data from a WIM file if needed.
409 Fixed a bug that could cause an error code to be incorrectly returned
410 when writing XML data containing a <WINDOWS> element.
412 Mounted WIM images will now correctly show the default file stream even
413 if appears in the alternate data stream entries of the corresponding WIM
417 Added a new experimental LZX compressor which can be enabled by passing
418 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
419 optimize'. (The latter is only applicable if the WIM is already
420 LZX-compressed and the '--recompress' option is also given.) The
421 experimental compressor is much slower but compresses the data slightly
422 more --- currently usually to within a fraction of a percent of the
423 results from WIMGAPI/ImageX.
425 A workaround has been added for compatibility with versions of WinPE
426 that interpret alternate data stream entries in the boot WIM
429 An alignment bug that caused a crash in the LZX decompressor on some
432 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
433 the WIM header when restoring the previous state of a WIM it failed to
436 Added a workaround to avoid an access denied error on Windows when
437 replacing a WIM file that another process has opened.
440 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
441 needed to be handled.
443 A bug in the interpretation of negative IMAGE indices in the
444 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
445 `wimlib-imagex append' has been fixed.
447 A workaround has been added to successfully apply security descriptors
448 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
449 2013.1.13 or earlier.
451 `wimlib-imagex capture' can now accept the '--delta-from' option
455 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
456 to standard output and applying images from standard input, but they are
457 not compatible with Microsoft's software and are not created by default.
458 See the documentation for --pipable flag of `wimlib-imagex capture' for
461 To better support incremental backups, added support for declaring an
462 image as a modified form of another image. See the documentation for
463 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
466 Added supported for "delta" WIMs. See the documentation for the
467 '--delta-from' option of `wimlib-imagex capture'.
469 The library support for managing split WIMs has been changed to support
470 other arrangements, such as delta WIMs, and be easier to use. This
471 change is visible in `wimlib-imagex', which also can now accept the
472 '--ref' option multiple times, and also now supports "delta" WIMs as
475 wimlib now preserves WIM integrity tables by default, even if
476 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
477 behavior of `wimlib-imagex' whenever the WIM being operated on contains
478 an integrity table and the '--check' option is not specified.
480 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
481 (when --compress is not specified). This provides the best compression
482 ratio by default, which is usually what is desired, at a cost of some
485 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
486 is the command as in `wimlib-imagex COMMAND'; for example, it can be
487 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
488 appropriate hard links are created in UNIX installations of
489 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
490 batch files that emulate this behavior are generated.
492 Security descriptors are now extracted correctly on Windows.
494 Fixed archiving DOS names in NTFS-3g capture mode.
496 The extraction code has been rewritten and it will now be easier to
497 support new features on all supported backends (currently Win32, UNIX,
498 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
499 now supported on all backends, not just UNIX.
501 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
502 than the WAIK itself.
504 wimlib_global_init() now, by default, attempts to acquire additional
505 privileges on Windows, so library clients need not do this.
507 This update bumps the shared library version number up to 9, since it is
508 not binary compatibible with previous releases.
511 Fixed bug in `wimlib-imagex export' that made it impossible to export an
512 image from a WIM that is readonly at the filesystem level.
514 Return error code rather than segfaulting when trying to list files from
515 a non-first part of a split WIM.
517 Joining a WIM will now preserve the RP_FIX and READONLY flags.
520 On Windows, paths given to wimlib-imagex are now treated case
523 Improved behavior regarding invalid filenames; in particular, on
524 Windows, wimlib-imagex will, when extracting, now omit (with an option
525 to override this default) filenames differing only in case, or filenames
526 containing characters not valid on Windows.
528 On Windows, wimlib now supports capturing and extracting long paths
529 (longer than the so-called MAX_PATH).
531 On Windows, `wimlib-imagex update' now acquires proper privileges when
532 running as an Administrator.
534 `wimlib-imagex update' will now complain if no image is specified when
535 trying to update a multi-image WIM.
537 `wimlib-imagex update' now supports specifying a single update command
538 directly on the command line using the --command option.
540 wimlib-imagex will now choose different units for progress messages,
541 depending on the amount of data that needs to be processed.
543 `wimlib-imagex append' will now generate a unique WIM image name if no
544 name is specified and the defaulted name already exists in the WIM.
546 wimlib now allows you to create unnamed WIM images, which can then only
547 be referred to by index.
549 wimlib now allows you to explicitly declare you want write access to a
550 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
553 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
556 Progress callbacks have been added to wimlib's wimlib_update_image()
559 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
560 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
563 NTFS-3g capture now only warns about two conditions previously treated
566 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
569 wimlib now correctly detects and returns an error when reading a WIM
570 image with a cyclic directory structure. (Fun fact: such a WIM will
571 crash Microsoft's software.)
574 Added new "extract" and "update" subcommands to wimlib-imagex, along
575 with associated APIs in the library. These commands are intended mainly
576 for Windows use but can be used on UNIX as well.
578 Many documentation improvements.
580 Fixed a bug in the Windows build where relative symbolic links were not
581 captured in reparse-point fixup mode.
583 Fixed a bug in the Windows build where file handles were left open to
584 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
586 Fixed a bug in the Windows build of wimlib-imagex where globbing
587 split-WIM parts could cause the program to crash.
589 Fixed a bug where the creation time of WIM images would be shown instead
590 of the last modification time.
592 With the Windows build it is now possible to restore a WIM containing
593 symbolic links as a non-Administrator; however you will receive warnings
594 about not being able to extract the symbolic links.
597 Capturing a WIM image should now be significantly faster in most cases
598 due to improved use of the operating system's cache and avoiding reading
599 files twice whenever possible.
601 The Windows build should now work on Windows XP.
603 The Windows build now supports capturing and restoring hidden,
604 compressed, sparse, and encrypted files.
606 The Windows build now supports capturing and applying WIM images from
607 filesystems other than NTFS (with some reduced functionality).
609 The Windows build now extracts short names correctly.
611 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
612 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
613 capture' and `wimlib-imagex apply'.
615 The performance of splitting and joining WIMs should be slightly
618 The LZX and XPRESS compression and decompression functions are now
619 exported from the library.
622 Improvements and bugfixes for the Windows build.
624 Added --strict-acls options.
626 Fixed the way that wimlib determines the order of images in the WIM.
629 Since wimlib can now be used on Windows, wimlib's implementation of
630 ImageX has been renamed to wimlib-imagex to avoid confusion with
631 Microsoft's implementation of ImageX, which would have the same file
632 name ("imagex.exe"). If you really don't like this you can pass the
633 --with-imagex-progname option to `configure' to choose a different name,
634 or even simply rename the binary yourself (but the former way will
635 configure the man pages to use the chosen name).
637 Various bugs fixed in the Windows build. Mainly to do with capturing
638 and restoring alternate data streams correctly in weird cases, and
639 requesting the correct privileges when opening files. Also added the
640 --noacls options to wimlib-imagex capture, append, and apply.
642 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
643 dynamically loaded, so this may make the library compatible with Windows
644 XP (however, there may still be other problems).
647 Added experimental support for native Windows builds. Binaries can be
648 downloaded from the SourceForge page.
650 --source-list option added to `imagex capture' and `imagex append'.
652 Better support for different character encodings.
655 Storing UNIX file owners, groups, and modes in WIM images is now
656 possible using `imagex capture' with the --unix-data flag.
658 Minor bug fixes and documentation fixes.
661 NTFS capture: Fixed capturing duplicate reparse points.
663 NTFS capture: Capture first unnamed stream if there are more than one
664 (print warning instead of error).
666 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
669 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
672 Update to work with ntfs-3g version 2013.1.13.
675 Fixed truncating file to shorter but non-zero length on read-write
678 Various code cleanups and minor documentation fixes.
681 LZX and XPRESS decompression have received some additional optimizations
682 and should now be even faster. (Although, they were already pretty
683 fast--- much faster than typical I/O speeds.)
685 Fixed a bug introduced in v1.2.1 that would cause a directory tree
686 containing hard links to be captured incorrectly in some cases.
689 By default, unmounting a read-write mounted WIM with 'imagex unmount
690 --commit' will now change the WIM in-place without needing to write the
691 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
694 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
695 for a response from the daemon servicing the mounted WIM. Instead,
696 every second 'imagex unmount' will check if the daemon is still alive,
697 and keep waiting if so, otherwise terminate with an error.
699 'imagex unmount --commit' on a read-write mounted WIM will now print
700 progress information regarding the writing of new or modified streams
701 the WIM, just like when capturing or appending a WIM.
703 A small change has been made to XPRESS compression and it should improve
704 the compression ratio slightly.
706 A change was made that may improve performance slightly when applying a
707 WIM image to a NTFS volume.
709 Microsoft has managed to introduce even more bugs into their software,
710 and now the WIMs for Windows 8 have incorrect (too low) reference counts
711 for some streams. This is unsafe because such streams can be removed
712 when they are in actuality still referenced in the WIM (perhaps by a
713 different image). wimlib will now work around this problem by fixing
714 the stream reference counts. This is only done when wimlib_delete_image() is
715 called ('imagex delete') or when wimlib_mount_image() is called with
716 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
717 requires reading the metadata for all images in the WIM, so this will
718 make these operations noticably slower on WIMs with multiple images.
720 Various other bugfixes.
723 Appending images to a WIM is now be done by default without re-building
724 the whole WIM. Use the --rebuild flag to get the old behavior (which
725 was to re-build the entire WIM when a new image is appended).
727 A new command `imagex optimize' is now available to manually re-build a
728 WIM that has wasted space due to repeated appends.
730 Progress information has been improved, and now arbitrary callback
731 functions can be used to show the progress of a WIM operation.
733 A possible bug with changing the bootable image of a WIM was fixed.
735 Some advisory locking is now done to prevent two processes from
736 modifying a WIM at the same time (but only in some cases). For example,
737 you cannot mount two images from a WIM read-write at the same time.
739 Some functions have been reorganized:
740 * wimlib_mount() renamed to wimlib_mount_image().
741 * wimlib_unmount() renamed to wimlib_unmount_image().
742 * wimlib_overwrite_xml_and_header() removed as
743 wimlib_overwrite() suffices now.
744 * wimlib_apply_image_to_ntfs_volume() removed as
745 wimlib_extract_image() suffices now.
746 * wimlib_add_image_from_ntfs_volume() removed as
747 * wimlib_add_image() suffices now.
749 Previously, the soname of libwim.so has been 0.0.0, despite many
750 interface changes. The soname is now updated to 1.0.0 and will now be
751 updated each release.
754 Resources will now be compressed using multiple threads by default.
755 (This applies to `imagex capture', `imagex append', and `imagex
758 Some performance improvements in mounted WIMs.
760 More progress information is shown when capturing a WIM.
763 Lots of minor fixes, code cleanups, and some documentation updates.
764 Nothing in particular is really noteworthy.
767 LZX and XPRESS compression improvements.
769 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
770 Link Bytes of the WIM.
773 Fixed bug when capturing NTFS file with multiple named data streams.
775 Internally, we are now using inode structures, even though these don't
776 appear literally in the WIM file. This simplifies some of the code
777 (mainly for WIM mounting) and likely fixed a few problems, although it
781 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
785 Enough changes to call it version 1.0.0!
787 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
788 to a NTFS volume, is now supported.
790 Hard links and symbolic links have much improved support. They are
791 supported for WIM capture, WIM application, and mounted WIMs (you can
792 even make them on read-write mounted WIMs).
794 Alternate data streams are now supported on mounted WIMs through an
795 xattr or a Windows-style stream interface. Also they are supported when
796 capturing a WIM from NTFS or applying a WIM to NTFS.
798 Split WIMs are better supported. You may now apply an image directly
799 from a split WIM, mount an image from a split WIM read-only, or export
800 an image from a split WIM.
802 Using a capture configuration file is now supported (but not fully yet).
804 SHA1 message digests are checked in more places, so we can make sure
805 applied and captured data is correct.
807 Man pages have been updated and consolidated.
810 Fixed segfault when unmounting read-only WIM.
813 Support for joining and splitting WIMs.
814 Also, security data is now preserved by default.
817 Can now build with older gcc and system headers, like on CentOS 5.
820 Fixed bug that made it impossible to overwrite files in read-write
824 Write byte-order mark before WIM XML data. (imagex.exe requires this to
