Only the most important changes more recent than version 0.6 are noted here.
+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 with Dism using '/compress recovery',
+ or using `wimcapture' using '--pack-streams', although wimlib's LZMS
+ compressor is not yet very good, the latter is not recommended. 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 overwridden
+ 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
