-Version 1.7.5-BETA:
- The performance of LZX compression has been improved by 15-20%. This is
- the default compression mode of wimlib-imagex.
+Version 1.8.4-BETA:
+ 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.
+
+ 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.
+
+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().
- Fixed various issues related to capture/apply of EFS-encrypted files on
- Windows.
+ On Windows, some error and warning messages have been improved.
Version 1.7.4:
The Windows binary distribution no longer contains third party DLLs.
