-Only the most important changes more recent than version 0.6 are noted here.
+Version 1.7.2-BETA:
+ 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.
+
+ Library changes:
+ Added file count progress data for
+ WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
+ WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
+
+ Added support for testing file exclusions via the user-provided
+ progress function.
+
+ Some documentation improvements.
+
+Version 1.7.1:
+ Made more improvements to the XPRESS, LZX, and LZMS compressors.
+
+ The default compression mode for wimcapture is now LZX compression in
+ its default mode, which is the same as '--compress=maximum'.
+
+ You can now specify an optional integer compression level to the
+ '--compress' option; e.g. '--compress=lzx:75'.
+
+ Made a minor change to the LZMS compressor and decompressor to fix an
+ incompatibility with the Microsoft implementation. In the unlikely
+ event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
+ earlier and a checksum error is reported when extracting files from it
+ with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
+ v1.7.1.
+
+ Added 'verify' subcommand to wimlib-imagex.
+
+ Notable 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.
+
+ Library users can now specify a custom file for warning and
+ error messages to be sent to, rather than the default of
+ standard error.
+
+ New progress messages:
+ WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
+ WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
+
+ New function: wimlib_verify_wim().
+
+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.
+
+ 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 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 <ARCH> 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, 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.
+
+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 <WINDOWS> 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.
+
+ wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
+ the WIM header when restoring the previous state of a WIM it failed to
+ successfully update.
+
+ Added a workaround to avoid an access denied error on Windows when
+ replacing a WIM file that another process has opened.
Version 1.5.1:
wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
needed to be handled.
- A bug related to the interpretation of the IMAGE in the
- --update-of=[WIMFILE:]IMAGE argument to `wimlib-imagex capture' and
+ A bug in the interpretation of negative IMAGE indices in the
+ --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
`wimlib-imagex append' has been fixed.
+ A workaround has been added to successfully apply security descriptors
+ with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
+ 2013.1.13 or earlier.
+
+ `wimlib-imagex capture' can now accept the '--delta-from' option
+ multiple times.
+
Version 1.5.0:
Added support for "pipable" WIMs. Pipable WIMs allow capturing images
to standard output and applying images from standard input, but they are
