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.
