Use the --no-replace option to get the + old behavior. + + Added support for "WIMBoot" capture and extraction.

If you captured any WIMs with + the --unix-data option, to upgrade them you'll need to apply them with + --unix-data using wimlib 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. + + On Windows, sparse file attributes are no longer set on extracted files. + + 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). + + - Progress functions, including their prototypes as well as how + they are provided to the library, have been changed. + + - '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. + + - 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. + + - Removed progress messages: + WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS, + WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN, + WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. + + - WIM paths passed to progress functions now have a leading + slash. + +Version 1.6.2: + Case-insensitive comparisons of strings (e.g. filenames) containing + UTF-16 codepoints above 32767 are now done correctly. + + Fixed build failure on Mac OS X. + + wimunmount now provides the '--new-image' option to cause changes to a + read-write mounted image to be committed as a new image rather than as + an update of the mounted image. (The corresponding new library flag is + WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.) + + The LZMS ("recovery") compression chunk size, or "dictionary size", may + now be up to 1 GiB (1,073,741,824 bytes). + + The performance of LZX ("maximum") and LZMS ("recovery") compression + with large chunk sizes has been slightly improved. + +Version 1.6.1: + Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now + decompressed correctly. + + Fixed a bug in the LZX compressor introduced in v1.5.3. The bug + occurred in an unlikely case, and due to validity checks it did not + affect successfully created archives. + + Fixed a minor compatibility issue with the LZMS compressor and + decompressor. This is *not* the default compression type and was only + introduced in v1.6.0. In the unlikely event that you created an + LZMS-compressed WIM with v1.6.0 and a checksum error is reported when + applying it with v1.6.1, decompress it with v1.6.0 then compress it with + v1.6.1. + + Memory usage for LZMS and LZX compression has been decreased. + + wimextract now allows wildcard characters in paths specified on the + command line. Also, the '--strict-wildcards' option has been removed + and replaced with the inverse option '--nullglob'. See the + documentation for wimextract for more details and changes. + + The wimlib_extract_files() function is now considered deprecated in + favor of wimlib_extract_paths(). + + Fixed more permissions problems when extracting files on Windows. + + A new '--no-attributes' option has been added to wimapply and + wimextract.
