Only the most important changes more recent than version 0.6 are noted here.
-Version 1.6.2 (BETA):
+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.
+
+ Performance improvements, including for extraction.
+
+ '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.
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 same image. (The corresponding new library flag is
+ an update of the mounted image. (The corresponding new library flag is
WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
- The LZMS compression chunk size, or "dictionary size", may now be up to
- 1 GiB (2^30).
+ 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 and LZMS compression with large chunk sizes has
- been slightly improved.
+ 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
