Only the most important changes more recent than version 0.6 are noted here. 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). 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! Capturing a WIM directly from a NTFS volume, and applying a WIM directly to a NTFS volume, is now supported. Hard links and symbolic links have much improved support. They are supported for WIM capture, WIM application, and mounted WIMs (you can even make them on read-write mounted WIMs). Alternate data streams are now supported on mounted WIMs through an 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). SHA1 message digests are checked in more places, so we can make sure applied and captured data is correct. Man pages have been updated and consolidated. Version 0.7.2: Fixed segfault when unmounting read-only WIM. Version 0.7.1: Support for joining and splitting WIMs. Also, security data is now preserved by default. Version 0.6.3: Can now build with older gcc and system headers, like on CentOS 5. Version 0.6.2: Fixed bug that made it impossible to overwrite files in read-write mount. Version 0.6.1: Write byte-order mark before WIM XML data. (imagex.exe requires this to be there.)
