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