These WIMs typically pack many streams ("files") together into a + single compressed resource, thereby saving space. This degrades the + performance of random access (such as that which occurs on a mounted + image), but optimizations have been implemented for extraction. These + new WIM files also typically use a new compression format (LZMS), which + is similar to LZMA and can offer a better compression ratio than LZX. + These new WIM files can be created using `wimcapture' with + the '--compress=lzms --pack-streams' options. Note: this new WIM format + is used by the Windows 8 web downloader, but important segments of the + raw '.esd' files are encrypted, so wimlib will not be able to extract + such files until they are first decrypted. + + wimlib now supports extracting files and directories from a WIM image + based on a "listfile" that itself contains the list of paths to extract. + For `wimextract', the syntax is to specify @LISTFILE instead of a PATH, + and for the library itself, the new APIs are wimlib_extract_pathlist() + and wimlib_extract_paths(). Path globs containing wildcard characters + are supported. + + For searching WIM files, wimlib now has configurable case sensitivity. + The default on Windows is still case-insensitive and the default on + UNIX-like systems is still case-sensitive, but this can be overridden + on either platform through flags to wimlib_global_init(). For + `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE + can be set to 1 or 0 for case-insensitive or case-sensitive behavior, + respectively. + + Support for compression chunk sizes greater than the default of 32768 + bytes has been added. A larger chunk size typically results in a better + compression ratio. However, the MS implementation is seemingly not + compatible with all chunk sizes, especially for LZX compression, so the + defaults remain unchanged, with the exception of the new LZMS-compressed + WIMs, which use a larger chunk size by default. + + The compression/decompression API exported by wimlib has been changed. + Now one set of functions handles all supported compression formats. + + `wimcapture' and `wimappend' will now display the progress of scanning + the directory tree to capture, in addition to the progress of writing + data to the WIM. The '--verbose' option no longer does anything. The + library API change for this is the addition of several members to + `struct wimlib_progress_info_scan' available to progress callbacks. + + `mkwinpeimg' now correctly handles the '--start-script' option when the + start script is not in the working directory. + + Sequential extraction, previously requested by using + WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default. + WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default + behavior (extract in file order). + +Version 1.5.3: + The new LZX compressor added in v1.5.2 has been improved and is now + enabled by default, except when `wimcapture' or `wimappend' is run + *without* the '--compress' option, in which case the faster LZX + compressor is used (the same as before). This behavior is reasonably + consistent with ImageX which actually uses "fast" (XPRESS) compression + by default. In those cases, use '--compress=maximum' to explicitly + capture a WIM image using the new (slower but better) LZX compressor. + + The '--compress-slow' option still exists to `wimlib-imagex optimize', + but its new behavior is to tweak the new LZX compressor even more to + produce an even better compression ratio at the cost of more time spent + compressing. + + `wimlib-imagex optimize' now supports the '--compress=TYPE' option, + which recompresses the WIM file using the specified compression TYPE. + The new library API function used for this is + wimlib_set_output_compression_type(). + + Added the wimlib_get_xml_data() function to allow library clients to + easily retrieve the raw XML data from a WIM file if needed. + + Fixed a bug that could cause an error code to be incorrectly returned + when writing XML data containing a element. + + Mounted WIM images will now correctly show the default file stream even + if appears in the alternate data stream entries of the corresponding WIM + directory entry. + Version 1.5.2: Added a new experimental LZX compressor which can be enabled by passing '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
