1 Only the most important changes more recent than version 0.6 are noted here.
4 Capturing a WIM image should now be significantly faster in most cases
5 due to improved use of the operating system's cache and avoiding reading
6 files twice whenever possible.
8 The Windows build now works on Windows XP.
10 On the Windows build, hidden directories are now correctly restored as
11 hidden. Also compressed, encrypted, and sparse files are now restored
14 The performance of splitting and joining WIMs should be slightly
17 The compression and decompression functions are now exported from the
21 Improvements and bugfixes for the Windows build.
23 Added --strict-acls options.
25 Fixed the way that wimlib determines the order of images in the WIM.
28 Since wimlib can now be used on Windows, wimlib's implementation of
29 ImageX has been renamed to wimlib-imagex to avoid confusion with
30 Microsoft's implementation of ImageX, which would have the same file
31 name ("imagex.exe"). If you really don't like this you can pass the
32 --with-imagex-progname option to `configure' to choose a different name,
33 or even simply rename the binary yourself (but the former way will
34 configure the man pages to use the chosen name).
36 Various bugs fixed in the Windows build. Mainly to do with capturing
37 and restoring alternate data streams correctly in weird cases, and
38 requesting the correct privileges when opening files. Also added the
39 --noacls options to wimlib-imagex capture, append, and apply.
41 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
42 dynamically loaded, so this may make the library compatible with Windows
43 XP (however, there may still be other problems).
46 Added experimental support for native Windows builds. Binaries can be
47 downloaded from the SourceForge page.
49 --source-list option added to `imagex capture' and `imagex append'.
51 Better support for different character encodings.
54 Storing UNIX file owners, groups, and modes in WIM images is now
55 possible using `imagex capture' with the --unix-data flag.
57 Minor bug fixes and documentation fixes.
60 NTFS capture: Fixed capturing duplicate reparse points.
62 NTFS capture: Capture first unnamed stream if there are more than one
63 (print warning instead of error).
65 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
68 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
71 Update to work with ntfs-3g version 2013.1.13.
74 Fixed truncating file to shorter but non-zero length on read-write
77 Various code cleanups and minor documentation fixes.
80 LZX and XPRESS decompression have received some additional optimizations
81 and should now be even faster. (Although, they were already pretty
82 fast--- much faster than typical I/O speeds.)
84 Fixed a bug introduced in v1.2.1 that would cause a directory tree
85 containing hard links to be captured incorrectly in some cases.
88 By default, unmounting a read-write mounted WIM with 'imagex unmount
89 --commit' will now change the WIM in-place without needing to write the
90 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
93 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
94 for a response from the daemon servicing the mounted WIM. Instead,
95 every second 'imagex unmount' will check if the daemon is still alive,
96 and keep waiting if so, otherwise terminate with an error.
98 'imagex unmount --commit' on a read-write mounted WIM will now print
99 progress information regarding the writing of new or modified streams
100 the WIM, just like when capturing or appending a WIM.
102 A small change has been made to XPRESS compression and it should improve
103 the compression ratio slightly.
105 A change was made that may improve performance slightly when applying a
106 WIM image to a NTFS volume.
108 Microsoft has managed to introduce even more bugs into their software,
109 and now the WIMs for Windows 8 have incorrect (too low) reference counts
110 for some streams. This is unsafe because such streams can be removed
111 when they are in actuality still referenced in the WIM (perhaps by a
112 different image). wimlib will now work around this problem by fixing
113 the stream reference counts. This is only done when wimlib_delete_image() is
114 called ('imagex delete') or when wimlib_mount_image() is called with
115 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
116 requires reading the metadata for all images in the WIM, so this will
117 make these operations noticably slower on WIMs with multiple images.
119 Various other bugfixes.
122 Appending images to a WIM is now be done by default without re-building
123 the whole WIM. Use the --rebuild flag to get the old behavior (which
124 was to re-build the entire WIM when a new image is appended).
126 A new command `imagex optimize' is now available to manually re-build a
127 WIM that has wasted space due to repeated appends.
129 Progress information has been improved, and now arbitrary callback
130 functions can be used to show the progress of a WIM operation.
132 A possible bug with changing the bootable image of a WIM was fixed.
134 Some advisory locking is now done to prevent two processes from
135 modifying a WIM at the same time (but only in some cases). For example,
136 you cannot mount two images from a WIM read-write at the same time.
138 Some functions have been reorganized:
139 * wimlib_mount() renamed to wimlib_mount_image().
140 * wimlib_unmount() renamed to wimlib_unmount_image().
141 * wimlib_overwrite_xml_and_header() removed as
142 wimlib_overwrite() suffices now.
143 * wimlib_apply_image_to_ntfs_volume() removed as
144 wimlib_extract_image() suffices now.
145 * wimlib_add_image_from_ntfs_volume() removed as
146 * wimlib_add_image() suffices now.
148 Previously, the soname of libwim.so has been 0.0.0, despite many
149 interface changes. The soname is now updated to 1.0.0 and will now be
150 updated each release.
153 Resources will now be compressed using multiple threads by default.
154 (This applies to `imagex capture', `imagex append', and `imagex
157 Some performance improvements in mounted WIMs.
159 More progress information is shown when capturing a WIM.
162 Lots of minor fixes, code cleanups, and some documentation updates.
163 Nothing in particular is really noteworthy.
166 LZX and XPRESS compression improvements.
168 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
169 Link Bytes of the WIM.
172 Fixed bug when capturing NTFS file with multiple named data streams.
174 Internally, we are now using inode structures, even though these don't
175 appear literally in the WIM file. This simplifies some of the code
176 (mainly for WIM mounting) and likely fixed a few problems, although it
180 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
184 Enough changes to call it version 1.0.0!
186 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
187 to a NTFS volume, is now supported.
189 Hard links and symbolic links have much improved support. They are
190 supported for WIM capture, WIM application, and mounted WIMs (you can
191 even make them on read-write mounted WIMs).
193 Alternate data streams are now supported on mounted WIMs through an
194 xattr or a Windows-style stream interface. Also they are supported when
195 capturing a WIM from NTFS or applying a WIM to NTFS.
197 Split WIMs are better supported. You may now apply an image directly
198 from a split WIM, mount an image from a split WIM read-only, or export
199 an image from a split WIM.
201 Using a capture configuration file is now supported (but not fully yet).
203 SHA1 message digests are checked in more places, so we can make sure
204 applied and captured data is correct.
206 Man pages have been updated and consolidated.
209 Fixed segfault when unmounting read-only WIM.
212 Support for joining and splitting WIMs.
213 Also, security data is now preserved by default.
216 Can now build with older gcc and system headers, like on CentOS 5.
219 Fixed bug that made it impossible to overwrite files in read-write
223 Write byte-order mark before WIM XML data. (imagex.exe requires this to
