On any platform, you can now capture a WIM - as WIMBoot-compatible. In addition, on Windows, you can now apply a WIM - archive in a special mode that causes extracted files to be externally - backed by the WIM archive. See the documentation for the new - '--wimboot' option to wimcapture and wimapply for more information. + The default compression mode for wimcapture is now LZX compression in + its default mode, which is the the same as '--compress=maximum'. + + You can now specify an optional integer compression level to the + '--compress' or '--solid-compress' options; e.g. '--compress=lzx:75'. + Currently, the default level in all cases is 50. This capability + deprecates the '--compress-slow' (or '--recompress-slow') option to + several wimlib-imagex commands. + + The '--pack-streams', '--pack-compress', and '--pack-chunk-size' options + to several wimlib-imagex commands have been deprecated in favor of more + "standard" names: '--solid', '--solid-compress', and + '--solid-chunk-size', respectively. + + The XPRESS compressor no longer supports chunks larger than 65536 bytes. + There is little point in having larger chunks, since the LZ77 sliding + window for XPRESS cannot be larger than 65536 bytes. This change does + not affect the default XPRESS chunk size, which is 32768. + + The new (as of v1.7.0) extraction code will no longer run out of file + handles when extracting many (1000+) identical files. + + 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. + + The maximum XPRESS chunk size has been reduced, as mentioned + above. + + Library users can now initialize and de-initialize the library + multiple times in one run of an application program. + + Library users will now receive WIMLIB_PROGRESS_MSG_WRITE_STREAMS + and WIMLIB_PROGRESS_MSG_EXTRACT_STREAMS messages more frequently + when writing or extracting large WIM files. + + Added experimental new write flag: + WIMLIB_WRITE_FLAG_SEND_DONE_WITH_FILE_MESSAGES. + + Library users can now specify a custom file for warning and + error messages to be sent to, rather than the default of + standard error. + +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. - Fixed reading out-of-order entries in lookup table of version 3584 WIM / - ESD files. + 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. + + On UNIX-like systems, you can now backup and restore device nodes, named + pipes, and sockets. In addition, 32-bit user and group IDs are now + supported. - The shared library version has been bumped up; however, there are only a - few incompatibilities: + The way that UNIX data is stored in WIM files has been changed. If you + captured any WIMs with the --unix-data option, to upgrade them you'll + need to apply them with --unix-data using wimlib-imagex v1.6.2, then + re-capture them with --unix-data using this version. + + wimlib now understands tagged metadata items, such as object IDs, that + can be stored in WIM directory entries. + + Removed the --hardlink and --symlink options to wimapply, since I don't + think they are too useful and they got in the way of improving the code. + + WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize). + + The 'mkwinpeimg' script now supports writing the ISO image to standard + output. + + The 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; + 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_XPRESS is now 1 and WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as WIMGAPI). + - 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, WIMLIB_EXTRACT_FLAG_FILE_ORDER, + and WIMLIB_EXTRACT_FLAG_SEQUENTIAL. + + - Removed some progress messages: + WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS, + WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN, + 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.
