On any platform, you can now capture a WIM + as WIMBoot-compatible. In addition, on Windows, specifically Windows + 8.1 Update 1 and later, 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, respectively, for more information. + + The shared library version has been bumped up; however, there are only + a few incompatibilities: + + - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and + WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as + WIMGAPI). + + - '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(). + + Otherwise the API and ABI is the same. + +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. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES. + + The default chunk size is now set correctly when changing the + compression type of a WIM, for example with 'wimoptimize'. + + The '--metadata' option to wiminfo has been replaced with the + '--detailed' option to wimdir. + + In relevant wimlib-imagex commands, '--solid' may now be used as an + alias for '--pack-streams'. + +Version 1.6.0: + Support for extracting and updating the new version 3584 WIMs has been + added. 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 + optimize'. (The latter is only applicable if the WIM is already + LZX-compressed and the '--recompress' option is also given.) The + experimental compressor is much slower but compresses the data slightly + more --- currently usually to within a fraction of a percent of the + results from WIMGAPI/ImageX. + + A workaround has been added for compatibility with versions of WinPE + that interpret alternate data stream entries in the boot WIM + incorrectly. + An alignment bug that caused a crash in the LZX decompressor on some builds was fixed. @@ -8,9 +184,8 @@ Version 1.5.2: the WIM header when restoring the previous state of a WIM it failed to successfully update. - A workaround has been added for compatibility with versions of WinPE - that interpret alternate data stream entries in the boot WIM - incorrectly. + Added a workaround to avoid an access denied error on Windows when + replacing a WIM file that another process has opened.
