-Only the most important changes more recent than version 0.6 are noted here.
+Version 1.9.0-BETA:
+ Added experimental support for Windows VSS (Volume Shadow Copy Service).
+ The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
+ create and use a temporary VSS snapshot when capturing a WIM image.
-Version 1.7.0-BETA:
- Improved compatibility with version 3584 WIM / ESD files.
+ Implemented setting of Windows-specific XML information, such as
+ architecture, system root, and version details. This information is now
+ automatically set in newly captured WIM images, when appropriate.
- Performance improvements, including for extraction.
+ Added a new '--image-property' option to 'wimcapture', 'wimappend', and
+ 'wiminfo'. This option lets you assign values to elements in a WIM
+ file's XML document by name.
+
+ The wimlib_get_image_property() and wimlib_set_image_property() API
+ functions now support numerically indexed elements.
+
+ Fixed a bug where, on Windows, wimlib would change the security
+ descriptor of the target directory of an extraction even when the
+ '--no-acls' option was specified.
+
+Version 1.8.3:
+ Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
+ some Microsoft software would not correctly recognize data in the
+ resulting filesystem.
+
+ Made some small improvements to the compression algorithms:
+ LZX compression ratio was slightly improved.
+ XPRESS compression ratio and speed was slightly improved.
+ LZMS compression speed was slightly improved.
+
+ Improved handling of WIM XML data. wimlib no longer drops unrecognized
+ elements when exporting images. In addition, two API functions were
+ added for better access to elements in the XML document:
+ wimlib_get_image_property() and wimlib_set_image_property().
+
+ Added support for (unsafe) in-place compaction of WIM files.
+
+ Improved performance of image export by reusing metadata resources
+ instead of always rebuilding and recompressing them.
+
+ Improved performance of wimlib_update_image() by delaying the update to
+ the WIM's XML document until a write is requested.
+
+ On Windows, the target of an extraction may now be a reparse point
+ (which will be dereferenced).
+
+ On Windows, wimlib now correctly restores non-Microsoft reparse points.
+ However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
+
+ On Windows, wimlib now has improved performance when archiving files
+ from a filesystem backed by a WIM (a "WIMBoot" setup).
+
+ Several improvements to System Compression (compact mode) support:
+
+ wof.sys (or wofadk.sys) is now automatically attached to the
+ target volume if needed.
+
+ Compact-mode extractions now work correctly with wofadk.sys on
+ older versions of Windows.
+
+ For compatibility with the Windows bootloader, the requested
+ compression format now is overridden on certain files.
+
+ Other minor bugfixes.
+
+Version 1.8.2:
+ This release primarily contains various minor bug fixes and
+ improvements, including:
+
+ Improved handling of deep directory structures.
+
+ Fixed a bug where on 32-bit systems, the library could enter an
+ infinite loop if a WIM file was malformed in a specific way.
+
+ Added a workaround for a case where libntfs-3g may report
+ duplicate streams in an NTFS file.
+
+ Windows symbolic links and junctions in mounted WIM images are
+ now automatically rewritten to be valid in the mounted location.
+
+ Reparse point fixes: correctly handle the "ReparseReserved"
+ field, and correctly handle "empty" (data-less) reparse points.
+
+ On Windows, wimlib now acquires SeManageVolumePrivilege, which
+ is needed to create externally backed files using the
+ "wofadk.sys" driver.
+
+ Improved validation of filenames.
+
+ Improved LZMS decompression speed.
+
+ The configure script now honors alternate pkg-config settings.
+
+ Links have been updated to point to the new website.
+
+ In addition, experimental support has been added for compressing
+ extracted files using System Compression on Windows 10. This
+ functionality is available through the new '--compact' option to
+ 'wimapply' and 'wimextract' as well as new library flags.
+
+Version 1.8.1:
+ Fixed a bug in the LZX decompressor: malicious input data could cause
+ out of bounds writes to memory (since wimlib v1.2.2).
+
+ The output of the 'wiminfo' command now consolidates various boolean
+ flags (such as "Relative path junction") into a single line.
+
+ A file can now have both an unnamed data stream ("file contents") and a
+ reparse point stream. Such files can exist as a result of the use of
+ certain Windows features, such as offline storage, including "OneDrive".
+ wimlib will now store and restore both streams on Windows as well as in
+ NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
+
+ On Windows, named data streams of encrypted files are no longer stored
+ twice in WIM archives.
+
+ On Windows, named data streams are now correctly extracted to existing
+ "readonly" directories. Before, an error would be reported.
+
+ On Windows, it is now possible to do a "WIMBoot mode" extraction with
+ non-standalone WIMs such as delta WIMs.
+
+ On Windows, when doing an extraction in "WIMBoot mode", files larger
+ than 4 gigabytes are now never extracted as externally backed. This
+ works around a bug in Microsoft's "WOF" driver.
+
+ The '--enable-verify-compression' configure option has been removed. If
+ you want to verify a WIM file, use the 'wimverify' program.
+
+ The way the "file count", "directory count", "total bytes", and "hard
+ link bytes" image statistics (stored in the WIM XML data) is calculated
+ has been slightly changed.
+
+ In mounted WIM images, the disk usage provided for each file (st_blocks)
+ is now the compressed size rather than the uncompressed size.
+
+ The performance of the NTFS-3g and Windows capture modes has been
+ slightly improved.
+
+ On UNIX-like systems, symbolic links whose targets contain the backslash
+ character are now handled correctly (losslessly).
+
+Version 1.8.0:
+ Improved the LZX compressor. It is now 15-20% faster than before and
+ provides a slightly better compression ratio.
+
+ Improved the LZMS compressor. It now provides a compression ratio
+ slightly better than WIMGAPI while still being faster and using slightly
+ less memory.
+
+ The compression chunk size in solid resources, e.g. when capturing or
+ exporting a WIM file using the '--solid' option, now defaults to 64 MiB
+ (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
+ better compression ratio and is the same value that WIMGAPI uses. The
+ memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
+ lower than WIMGAPI's memory usage, but if it is too much, it is still
+ possible to choose a lower value, e.g. with the '--solid-chunk-size'
+ option to wimlib-imagex.
+
+ The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
+ accept the 'K', 'M', and 'G' suffixes.
+
+ Files are now sorted by name extension when creating a solid WIM file.
+
+ Fixed various issues related to capture/apply of EFS-encrypted files on
+ Windows.
+
+ The file list printed by 'wimdir' is now sorted by the platform-specific
+ case sensitivity setting, rather than always case sensitively. This
+ also affects the library function wimlib_iterate_dir_tree().
+
+ On Windows, some error and warning messages have been improved.
+
+Version 1.7.4:
+ The Windows binary distribution no longer contains third party DLLs.
+ These dependencies are instead compiled directly into the libwim DLL.
+
+ Added more fixes for wimlib on non-x86 architectures such as ARM.
+
+ Extracting files to a Windows PE in-memory filesystem no longer fails if
+ the target files do not yet exist.
+
+ Improved the performance of XPRESS compression and LZMS decompression.
+
+ Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
+ It will automatically be faster on newer Intel and AMD processors.
+
+ Removed the --with-imagex-progname and --enable-more-assertions
+ configure options.
+
+Version 1.7.3:
+ Fix for very slow export from solid WIM / ESD files.
+
+ Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
+
+ New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
+ may use this to treat some types of errors as non-fatal.
+
+ The library now permits making in-memory changes to a WIMStruct backed
+ by a read-only WIM file.
+
+ Fixes for "WIMBoot" extraction mode (Windows only):
+
+ When not using the WOF driver, extraction no longer fails if the
+ disk containing the WIM file has too many partitions.
+
+ When matching patterns in [PrepopulateList], all hard links of
+ each file are now considered.
+
+ The system registry files are now automatically treated as being
+ in [PrepopulateList].
+
+ Added a hack to try to work around an intermittent bug in
+ Microsoft's WOF (Windows Overlay Filesystem) driver.
+
+Version 1.7.2:
+ Made more improvements to the XPRESS, LZX, and LZMS compressors.
+
+ A number of improvements to the Windows port:
+
+ Fixes for setting short filenames.
+
+ Faster "WIMBoot" extraction.
+
+ Updated and slimmed down the dependent DLLs.
+
+ ACL inheritence bits are now restored.
+
+ Mandatory integrity labels are now backed up and restored.
+
+ Added a workaround for an issue where in rare cases, wimlib could create
+ a compressed data stream that could not be read correctly by Windows
+ after an extraction in "WIMBoot" mode.
+
+ Library changes:
+ Added file count progress data for
+ WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
+ WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
+
+ Added support for testing file exclusions via the user-provided
+ progress function.
+
+ Some documentation improvements.
+
+ Made some clarifications to the license text in the COPYING file.
+
+Version 1.7.1:
+ Made more improvements to the XPRESS, LZX, and LZMS compressors.
+
+ The default compression mode for wimcapture is now LZX compression in
+ its default mode, which is the same as '--compress=maximum'.
+
+ You can now specify an optional integer compression level to the
+ '--compress' option; e.g. '--compress=lzx:75'.
+
+ Made a minor change to the LZMS compressor and decompressor to fix an
+ incompatibility with the Microsoft implementation. In the unlikely
+ event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
+ earlier and a checksum error is reported when extracting files from it
+ with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
+ v1.7.1.
+
+ Added 'verify' subcommand to wimlib-imagex.
+
+ Notable library changes:
+
+ Custom compressor parameters have been removed from the library
+ in favor of the simpler level-based API.
+
+ Decompressor parameters have been removed entirely.
+
+ Library users can now specify a custom file for warning and
+ error messages to be sent to, rather than the default of
+ standard error.
+
+ New progress messages:
+ WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
+ WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
+
+ New function: wimlib_verify_wim().
+
+Version 1.7.0:
+ Improved compression, decompression, and extraction performance.
+
+ Improved compatibility with version 3584 WIM / ESD files:
+ - Add support for reading and writing multiple solid blocks per
+ archive, which WIMGAPI/DISM can create when appending an image.
+ - Correctly create solid blocks larger than 4 GiB.
'add' commands passed to wimupdate will now replace existing
nondirectory files by default. Use the --no-replace option to get the
old behavior.
+ The license for the library now contains an exception that allows using
+ it under the LGPL. See the COPYING file for details.
+
+ In reparse-point fixup mode (the default for capture), symbolic links
+ and junctions that point outside the tree being captured are no longer
+ excluded from capture.
+
Added support for "WIMBoot" capture and extraction. See the
documentation for the new '--wimboot' option to wimcapture and wimapply
for more information.
The 'mkwinpeimg' script now supports writing the ISO image to standard
output.
- The <ARCH> element in WIM XML data will now be exported correctly.
+ The <ARCH> element in WIM XML data is now exported correctly.
On Windows, sparse file attributes are no longer set on extracted files.
+ Oddly enough, this actually saves disk space in some cases.
On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
supported. Mounting WIM images now always requires extended attribute
- support. Use --without-fuse to disable support for mounting WIM images.
+ support. Use --without-fuse to disable support for mounting WIM images;
+ this will also disable the need for extended attribute support.
+
+ Configuring with --enable-ssse3-sha1 now works correctly.
The shared library version has been bumped up. The main
incompatibilities are:
WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
WIMGAPI).
- - Progress functions, including their prototypes as well as how
- they are provided to the library, have been changed.
+ - User-provided progress functions are now registered using a
+ separate function, wimlib_register_progress_function(). The
+ 'progress_func' argument to many functions no longer exists.
+
+ - The return value from user-provided progress functions is now
+ significant.
+
+ - A context argument has been added to the prototype of
+ user-provided progress functions.
- 'struct wimlib_capture_config' has been removed. The library
now takes the path to the configuration file directly. This
affects wimlib_add_image(), wimlib_add_image_multisource(),
- and wimlib_update_image(). However no code changes are
- necessary if a NULL configuration was being used.
+ and wimlib_update_image(). However, a NULL value passed in
+ the argument retains the same meaning.
- Removed deprecated functions: some (de)compression functions,
wimlib_extract_files(), and wimlib_print_metadata().
- Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
- WIMLIB_EXTRACT_FLAG_SYMLINK, and
- WIMLIB_EXTRACT_FLAG_FILE_ORDER.
+ WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
+ and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
- - Removed progress messages:
+ - Removed some progress messages:
WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
- WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END.
+ WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
+ stays the same.
+
+ - Removed some error codes. Numbering stays the same.
+
+ - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
+ WIMLIB_UNMOUNT_FLAG_FORCE.
- WIM paths passed to progress functions now have a leading
slash.
