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