Only the most important changes more recent than version 0.6 are noted here.
+Version 1.7.0-BETA:
+ 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.
+
+ Improved decompression, compression, and extraction performance.
+
+ 'add' commands passed to wimupdate will now replace existing
+ nondirectory files by default. Use the --no-replace option to get the
+ old behavior.
+
+ 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 will now be 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.
+
+ 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, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
+ and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
+
+ - Removed 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 a
+ 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.
- Paths passed to wimlib_extract_paths() and wimlib_iterate_dir_tree() may
- now use either forwards or backwards slashes, as documented.
+ A new '--no-attributes' option has been added to wimapply and
+ wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
- Fixed a potential stack overflow when extracting solid archives
- containing more than about 100000 files.
+ The default chunk size is now set correctly when changing the
+ compression type of a WIM, for example with 'wimoptimize'.
- Memory usage for LZMS and LZX compression has been decreased.
+ The '--metadata' option to wiminfo has been replaced with the
+ '--detailed' option to wimdir.
- For wimcapture, wimoptimize, and wimexport, '--solid' may now be used as
- an alias for '--pack-streams'.
+ 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
