Only the most important changes more recent than version 0.6 are noted here.
+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.
+
+ 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.
+
+ A workaround has been added for compatibility with versions of WinPE
+ that interpret alternate data stream entries in the boot WIM
+ incorrectly.
+
+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 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
+ not compatible with Microsoft's software and are not created by default.
+ See the documentation for --pipable flag of `wimlib-imagex capture' for
+ more information.
+
+ To better support incremental backups, added support for declaring an
+ image as a modified form of another image. See the documentation for
+ the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
+ capture'.
+
+ Added supported for "delta" WIMs. See the documentation for the
+ '--delta-from' option of `wimlib-imagex capture'.
+
+ The library support for managing split WIMs has been changed to support
+ other arrangements, such as delta WIMs, and be easier to use. This
+ change is visible in `wimlib-imagex', which also can now accept the
+ '--ref' option multiple times, and also now supports "delta" WIMs as
+ mentioned above.
+
+ wimlib now preserves WIM integrity tables by default, even if
+ WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
+ behavior of `wimlib-imagex' whenever the WIM being operated on contains
+ an integrity table and the '--check' option is not specified.
+
+ `wimlib-imagex capture' now creates LZX-compressed WIMs by default
+ (when --compress is not specified). This provides the best compression
+ ratio by default, which is usually what is desired, at a cost of some
+ speed.
+
+ `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
+ is the command as in `wimlib-imagex COMMAND'; for example, it can be
+ invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
+ appropriate hard links are created in UNIX installations of
+ `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
+ batch files that emulate this behavior are generated.
+
+ Security descriptors are now extracted correctly on Windows.
+
+ Fixed archiving DOS names in NTFS-3g capture mode.
+
+ The extraction code has been rewritten and it will now be easier to
+ support new features on all supported backends (currently Win32, UNIX,
+ and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
+ now supported on all backends, not just UNIX.
+
+ `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
+ than the WAIK itself.
+
+ wimlib_global_init() now, by default, attempts to acquire additional
+ privileges on Windows, so library clients need not do this.
+
+ This update bumps the shared library version number up to 9, since it is
+ not binary compatibible with previous releases.
+
+Version 1.4.2:
+ Fixed bug in `wimlib-imagex export' that made it impossible to export an
+ image from a WIM that is readonly at the filesystem level.
+
+ Return error code rather than segfaulting when trying to list files from
+ a non-first part of a split WIM.
+
+ Joining a WIM will now preserve the RP_FIX and READONLY flags.
+
+Version 1.4.1:
+ On Windows, paths given to wimlib-imagex are now treated case
+ insensitively.
+
+ Improved behavior regarding invalid filenames; in particular, on
+ Windows, wimlib-imagex will, when extracting, now omit (with an option
+ to override this default) filenames differing only in case, or filenames
+ containing characters not valid on Windows.
+
+ On Windows, wimlib now supports capturing and extracting long paths
+ (longer than the so-called MAX_PATH).
+
+ On Windows, `wimlib-imagex update' now acquires proper privileges when
+ running as an Administrator.
+
+ `wimlib-imagex update' will now complain if no image is specified when
+ trying to update a multi-image WIM.
+
+ `wimlib-imagex update' now supports specifying a single update command
+ directly on the command line using the --command option.
+
+ wimlib-imagex will now choose different units for progress messages,
+ depending on the amount of data that needs to be processed.
+
+ `wimlib-imagex append' will now generate a unique WIM image name if no
+ name is specified and the defaulted name already exists in the WIM.
+
+ wimlib now allows you to create unnamed WIM images, which can then only
+ be referred to by index.
+
+ wimlib now allows you to explicitly declare you want write access to a
+ WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
+ wimlib_open_wim().
+
+ wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
+ header.
+
+ Progress callbacks have been added to wimlib's wimlib_update_image()
+ function.
+
+ Added wimlib_get_wim_info(), wimlib_set_wim_info(),
+ wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
+ to the library.
+
+ NTFS-3g capture now only warns about two conditions previously treated
+ as errors.
+
+ Fixed a couple issues with using wimlib-imagex on UDF filesystems on
+ Windows.
+
+ wimlib now correctly detects and returns an error when reading a WIM
+ image with a cyclic directory structure. (Fun fact: such a WIM will
+ crash Microsoft's software.)
+
+Version 1.4.0:
+ Added new "extract" and "update" subcommands to wimlib-imagex, along
+ with associated APIs in the library. These commands are intended mainly
+ for Windows use but can be used on UNIX as well.
+
+ Many documentation improvements.
+
+ Fixed a bug in the Windows build where relative symbolic links were not
+ captured in reparse-point fixup mode.
+
+ Fixed a bug in the Windows build where file handles were left open to
+ the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
+
+ Fixed a bug in the Windows build of wimlib-imagex where globbing
+ split-WIM parts could cause the program to crash.
+
+ Fixed a bug where the creation time of WIM images would be shown instead
+ of the last modification time.
+
+ With the Windows build it is now possible to restore a WIM containing
+ symbolic links as a non-Administrator; however you will receive warnings
+ about not being able to extract the symbolic links.
+
+Version 1.3.3:
+ Capturing a WIM image should now be significantly faster in most cases
+ due to improved use of the operating system's cache and avoiding reading
+ files twice whenever possible.
+
+ The Windows build should now work on Windows XP.
+
+ The Windows build now supports capturing and restoring hidden,
+ compressed, sparse, and encrypted files.
+
+ The Windows build now supports capturing and applying WIM images from
+ filesystems other than NTFS (with some reduced functionality).
+
+ The Windows build now extracts short names correctly.
+
+ Added support for "reparse-point" fixups (i.e. fixing up of symbolic
+ links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
+ capture' and `wimlib-imagex apply'.
+
+ The performance of splitting and joining WIMs should be slightly
+ improved.
+
+ The LZX and XPRESS compression and decompression functions are now
+ exported from the library.
+
+Version 1.3.2:
+ Improvements and bugfixes for the Windows build.
+
+ Added --strict-acls options.
+
+ Fixed the way that wimlib determines the order of images in the WIM.
+
+Version 1.3.1:
+ Since wimlib can now be used on Windows, wimlib's implementation of
+ ImageX has been renamed to wimlib-imagex to avoid confusion with
+ Microsoft's implementation of ImageX, which would have the same file
+ name ("imagex.exe"). If you really don't like this you can pass the
+ --with-imagex-progname option to `configure' to choose a different name,
+ or even simply rename the binary yourself (but the former way will
+ configure the man pages to use the chosen name).
+
+ Various bugs fixed in the Windows build. Mainly to do with capturing
+ and restoring alternate data streams correctly in weird cases, and
+ requesting the correct privileges when opening files. Also added the
+ --noacls options to wimlib-imagex capture, append, and apply.
+
+ Windows build again: FindFirstStreamW() and FindNextStreamW() are now
+ dynamically loaded, so this may make the library compatible with Windows
+ XP (however, there may still be other problems).
+
+Version 1.3.0:
+ Added experimental support for native Windows builds. Binaries can be
+ downloaded from the SourceForge page.
+
+ --source-list option added to `imagex capture' and `imagex append'.
+
+ Better support for different character encodings.
+
+Version 1.2.6:
+ Storing UNIX file owners, groups, and modes in WIM images is now
+ possible using `imagex capture' with the --unix-data flag.
+
+ Minor bug fixes and documentation fixes.
+
+Version 1.2.5:
+ NTFS capture: Fixed capturing duplicate reparse points.
+
+ NTFS capture: Capture first unnamed stream if there are more than one
+ (print warning instead of error).
+
+ Allow multiple test cases to execute concurrently (e.g. make -j2 check).
+
+Version 1.2.4:
+ Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
+ from the WAIK.
+
+ Update to work with ntfs-3g version 2013.1.13.
+
+Version 1.2.3:
+ Fixed truncating file to shorter but non-zero length on read-write
+ mounted WIM image.
+
+ Various code cleanups and minor documentation fixes.
+
+Version 1.2.2:
+ LZX and XPRESS decompression have received some additional optimizations
+ and should now be even faster. (Although, they were already pretty
+ fast--- much faster than typical I/O speeds.)
+
+ Fixed a bug introduced in v1.2.1 that would cause a directory tree
+ containing hard links to be captured incorrectly in some cases.
+
+Version 1.2.1:
+ By default, unmounting a read-write mounted WIM with 'imagex unmount
+ --commit' will now change the WIM in-place without needing to write the
+ entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
+ old behavior.
+
+ 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
+ for a response from the daemon servicing the mounted WIM. Instead,
+ every second 'imagex unmount' will check if the daemon is still alive,
+ and keep waiting if so, otherwise terminate with an error.
+
+ 'imagex unmount --commit' on a read-write mounted WIM will now print
+ progress information regarding the writing of new or modified streams
+ the WIM, just like when capturing or appending a WIM.
+
+ A small change has been made to XPRESS compression and it should improve
+ the compression ratio slightly.
+
+ A change was made that may improve performance slightly when applying a
+ WIM image to a NTFS volume.
+
+ Microsoft has managed to introduce even more bugs into their software,
+ and now the WIMs for Windows 8 have incorrect (too low) reference counts
+ for some streams. This is unsafe because such streams can be removed
+ when they are in actuality still referenced in the WIM (perhaps by a
+ different image). wimlib will now work around this problem by fixing
+ the stream reference counts. This is only done when wimlib_delete_image() is
+ called ('imagex delete') or when wimlib_mount_image() is called with
+ WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
+ requires reading the metadata for all images in the WIM, so this will
+ make these operations noticably slower on WIMs with multiple images.
+
+ Various other bugfixes.
+
+Version 1.2.0:
+ Appending images to a WIM is now be done by default without re-building
+ the whole WIM. Use the --rebuild flag to get the old behavior (which
+ was to re-build the entire WIM when a new image is appended).
+
+ A new command `imagex optimize' is now available to manually re-build a
+ WIM that has wasted space due to repeated appends.
+
+ Progress information has been improved, and now arbitrary callback
+ functions can be used to show the progress of a WIM operation.
+
+ A possible bug with changing the bootable image of a WIM was fixed.
+
+ Some advisory locking is now done to prevent two processes from
+ modifying a WIM at the same time (but only in some cases). For example,
+ you cannot mount two images from a WIM read-write at the same time.
+
+ Some functions have been reorganized:
+ * wimlib_mount() renamed to wimlib_mount_image().
+ * wimlib_unmount() renamed to wimlib_unmount_image().
+ * wimlib_overwrite_xml_and_header() removed as
+ wimlib_overwrite() suffices now.
+ * wimlib_apply_image_to_ntfs_volume() removed as
+ wimlib_extract_image() suffices now.
+ * wimlib_add_image_from_ntfs_volume() removed as
+ * wimlib_add_image() suffices now.
+
+ Previously, the soname of libwim.so has been 0.0.0, despite many
+ interface changes. The soname is now updated to 1.0.0 and will now be
+ updated each release.
+
+Version 1.1.0:
+ Resources will now be compressed using multiple threads by default.
+ (This applies to `imagex capture', `imagex append', and `imagex
+ export').
+
+ Some performance improvements in mounted WIMs.
+
+ More progress information is shown when capturing a WIM.
+
+Version 1.0.4:
+ Lots of minor fixes, code cleanups, and some documentation updates.
+ Nothing in particular is really noteworthy.
+
+Version 1.0.3:
+ LZX and XPRESS compression improvements.
+
+ Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
+ Link Bytes of the WIM.
+
+Version 1.0.2:
+ Fixed bug when capturing NTFS file with multiple named data streams.
+
+ Internally, we are now using inode structures, even though these don't
+ appear literally in the WIM file. This simplifies some of the code
+ (mainly for WIM mounting) and likely fixed a few problems, although it
+ needs more testing.
+
+Version 1.0.1:
+ Fixed problem when exporting images from XPRESS to LZX compressed WIM or
+ vice versa
+
Version 1.0.0:
Enough changes to call it version 1.0.0!
xattr or a Windows-style stream interface. Also they are supported when
capturing a WIM from NTFS or applying a WIM to NTFS.
+ Split WIMs are better supported. You may now apply an image directly
+ from a split WIM, mount an image from a split WIM read-only, or export
+ an image from a split WIM.
+
Using a capture configuration file is now supported (but not fully yet).
