Only the most important changes more recent than version 0.6 are noted here.
+Version 1.6.3-BETA:
+ Added support for "WIMBoot". On any platform, you can now capture a WIM
+ as WIMBoot-compatible. In addition, on Windows, you can now apply a WIM
+ archive in a special mode that causes extracted files to be externally
+ backed by the WIM archive. See the documentation for the new
+ '--wimboot' option to wimcapture and wimapply for more information.
+
+ 'add' commands passed to wimupdate will now replace existing
+ nondirectory files by default. Use the --no-replace option to get the
+ old behavior.
+
+ Fixed reading out-of-order entries in lookup table of version 3584 WIM /
+ ESD files.
+
+ The shared library version has been bumped up; however, there are only a
+ few incompatibilities:
+
+ - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
+ WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
+ WIMGAPI).
+
+ - '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().
+
+ - 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.
