-Only the most important changes more recent than version 0.6 are noted here.
+Version 1.7.3-BETA:
+ Fix for very slow export from solid WIM / ESD files.
+
+ Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
+
+ New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
+ may use this to treat some types of errors as non-fatal.
+
+ The library now permits making in-memory changes to a WIMStruct backed
+ by a read-only WIM file.
+
+ Fixes for "WIMBoot" extraction mode (Windows only):
+
+ When not using the WOF driver, extraction no longer fails if the
+ disk containing the WIM file has too many partitions.
+
+ When matching patterns in [PrepopulateList], all hard links of
+ each file are now considered.
+
+ The system registry files are now automatically treated as being
+ in [PrepopulateList].
+
+ Added a hack to try to work around an intermittent bug in
+ Microsoft's WOF (Windows Overlay Filesystem) driver.
+
+Version 1.7.2:
+ 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.
+
+ Added a workaround for an issue where in rare cases, wimlib could create
+ a compressed data stream that could not be read correctly by Windows
+ after an extraction in "WIMBoot" mode.
+
+ 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.
+
+ Made some clarifications to the license text in the COPYING file.
+
+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 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.
- wimextract now allows wildcard characters in paths specified on the
- command line (not just in a list file, as was added in v1.6.0).
-
- wimextract now allows a command line to contain multiple list files,
- possibly interspersed with direct paths.
+ Memory usage for LZMS and LZX compression has been decreased.
- The '--strict-wildcards' option to wimextract has been removed and
- replaced with the inverse option '--nullglob' --- that is, the default
- behavior is now to issue an error when any path (possibly containing
- wildcard characters) does not match any paths in the WIM image, and this
- can be changed by specifying '--nullglob'.
+ 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.
- Added '--preserve-dir-structure' option to wimextract.
+ The wimlib_extract_files() function is now considered deprecated in
+ favor of wimlib_extract_paths().
Fixed more permissions problems when extracting files on Windows.
- Memory usage for LZMS and LZX compression has been decreased.
-
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 (this bug caused wimoptimize to fail when
- changing the compression type from None to LZX with no chunk size
- explicitly specified, for example).
-
- wiminfo no longer accepts the '--metadata' option. Use the new
- '--detailed' option to wimdir instead. (This is primarily for
- debugging.)
-
- Paths passed to wimlib_extract_paths() and wimlib_iterate_dir_tree() may
- now use either forwards or backwards slashes, as documented.
+ compression type of a WIM, for example with 'wimoptimize'.
- Fixed a potential stack overflow when extracting solid archives
- containing more than about 100000 files.
+ 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
