1 Only the most important changes more recent than version 0.6 are noted here.
4 Fixed a bug in the Windows build where relative symbolic links were not
5 captured in reparse-point fixup mode.
7 Fixed a bug in the Windows build where file handles were left open to
8 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
10 Fixed a bug in the Windows build of wimlib-imagex where globbing
11 split-WIM parts could cause a crash.
13 With the Windows build it is now possible to restore a WIM containing
14 symbolic links as a non-Administrator; however you will receive warnings
15 about not being able to extract the symbolic links.
18 Capturing a WIM image should now be significantly faster in most cases
19 due to improved use of the operating system's cache and avoiding reading
20 files twice whenever possible.
22 The Windows build should now work on Windows XP.
24 The Windows build now supports capturing and restoring hidden,
25 compressed, sparse, and encrypted files.
27 The Windows build now supports capturing and applying WIM images from
28 filesystems other than NTFS (with some reduced functionality).
30 The Windows build now extracts short names correctly.
32 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
33 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
34 capture' and `wimlib-imagex apply'.
36 The performance of splitting and joining WIMs should be slightly
39 The LZX and XPRESS compression and decompression functions are now
40 exported from the library.
43 Improvements and bugfixes for the Windows build.
45 Added --strict-acls options.
47 Fixed the way that wimlib determines the order of images in the WIM.
50 Since wimlib can now be used on Windows, wimlib's implementation of
51 ImageX has been renamed to wimlib-imagex to avoid confusion with
52 Microsoft's implementation of ImageX, which would have the same file
53 name ("imagex.exe"). If you really don't like this you can pass the
54 --with-imagex-progname option to `configure' to choose a different name,
55 or even simply rename the binary yourself (but the former way will
56 configure the man pages to use the chosen name).
58 Various bugs fixed in the Windows build. Mainly to do with capturing
59 and restoring alternate data streams correctly in weird cases, and
60 requesting the correct privileges when opening files. Also added the
61 --noacls options to wimlib-imagex capture, append, and apply.
63 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
64 dynamically loaded, so this may make the library compatible with Windows
65 XP (however, there may still be other problems).
68 Added experimental support for native Windows builds. Binaries can be
69 downloaded from the SourceForge page.
71 --source-list option added to `imagex capture' and `imagex append'.
73 Better support for different character encodings.
76 Storing UNIX file owners, groups, and modes in WIM images is now
77 possible using `imagex capture' with the --unix-data flag.
79 Minor bug fixes and documentation fixes.
82 NTFS capture: Fixed capturing duplicate reparse points.
84 NTFS capture: Capture first unnamed stream if there are more than one
85 (print warning instead of error).
87 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
90 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
93 Update to work with ntfs-3g version 2013.1.13.
96 Fixed truncating file to shorter but non-zero length on read-write
99 Various code cleanups and minor documentation fixes.
102 LZX and XPRESS decompression have received some additional optimizations
103 and should now be even faster. (Although, they were already pretty
104 fast--- much faster than typical I/O speeds.)
106 Fixed a bug introduced in v1.2.1 that would cause a directory tree
107 containing hard links to be captured incorrectly in some cases.
110 By default, unmounting a read-write mounted WIM with 'imagex unmount
111 --commit' will now change the WIM in-place without needing to write the
112 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
115 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
116 for a response from the daemon servicing the mounted WIM. Instead,
117 every second 'imagex unmount' will check if the daemon is still alive,
118 and keep waiting if so, otherwise terminate with an error.
120 'imagex unmount --commit' on a read-write mounted WIM will now print
121 progress information regarding the writing of new or modified streams
122 the WIM, just like when capturing or appending a WIM.
124 A small change has been made to XPRESS compression and it should improve
125 the compression ratio slightly.
127 A change was made that may improve performance slightly when applying a
128 WIM image to a NTFS volume.
130 Microsoft has managed to introduce even more bugs into their software,
131 and now the WIMs for Windows 8 have incorrect (too low) reference counts
132 for some streams. This is unsafe because such streams can be removed
133 when they are in actuality still referenced in the WIM (perhaps by a
134 different image). wimlib will now work around this problem by fixing
135 the stream reference counts. This is only done when wimlib_delete_image() is
136 called ('imagex delete') or when wimlib_mount_image() is called with
137 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
138 requires reading the metadata for all images in the WIM, so this will
139 make these operations noticably slower on WIMs with multiple images.
141 Various other bugfixes.
144 Appending images to a WIM is now be done by default without re-building
145 the whole WIM. Use the --rebuild flag to get the old behavior (which
146 was to re-build the entire WIM when a new image is appended).
148 A new command `imagex optimize' is now available to manually re-build a
149 WIM that has wasted space due to repeated appends.
151 Progress information has been improved, and now arbitrary callback
152 functions can be used to show the progress of a WIM operation.
154 A possible bug with changing the bootable image of a WIM was fixed.
156 Some advisory locking is now done to prevent two processes from
157 modifying a WIM at the same time (but only in some cases). For example,
158 you cannot mount two images from a WIM read-write at the same time.
160 Some functions have been reorganized:
161 * wimlib_mount() renamed to wimlib_mount_image().
162 * wimlib_unmount() renamed to wimlib_unmount_image().
163 * wimlib_overwrite_xml_and_header() removed as
164 wimlib_overwrite() suffices now.
165 * wimlib_apply_image_to_ntfs_volume() removed as
166 wimlib_extract_image() suffices now.
167 * wimlib_add_image_from_ntfs_volume() removed as
168 * wimlib_add_image() suffices now.
170 Previously, the soname of libwim.so has been 0.0.0, despite many
171 interface changes. The soname is now updated to 1.0.0 and will now be
172 updated each release.
175 Resources will now be compressed using multiple threads by default.
176 (This applies to `imagex capture', `imagex append', and `imagex
179 Some performance improvements in mounted WIMs.
181 More progress information is shown when capturing a WIM.
184 Lots of minor fixes, code cleanups, and some documentation updates.
185 Nothing in particular is really noteworthy.
188 LZX and XPRESS compression improvements.
190 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
191 Link Bytes of the WIM.
194 Fixed bug when capturing NTFS file with multiple named data streams.
196 Internally, we are now using inode structures, even though these don't
197 appear literally in the WIM file. This simplifies some of the code
198 (mainly for WIM mounting) and likely fixed a few problems, although it
202 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
206 Enough changes to call it version 1.0.0!
208 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
209 to a NTFS volume, is now supported.
211 Hard links and symbolic links have much improved support. They are
212 supported for WIM capture, WIM application, and mounted WIMs (you can
213 even make them on read-write mounted WIMs).
215 Alternate data streams are now supported on mounted WIMs through an
216 xattr or a Windows-style stream interface. Also they are supported when
217 capturing a WIM from NTFS or applying a WIM to NTFS.
219 Split WIMs are better supported. You may now apply an image directly
220 from a split WIM, mount an image from a split WIM read-only, or export
221 an image from a split WIM.
223 Using a capture configuration file is now supported (but not fully yet).
225 SHA1 message digests are checked in more places, so we can make sure
226 applied and captured data is correct.
228 Man pages have been updated and consolidated.
231 Fixed segfault when unmounting read-only WIM.
234 Support for joining and splitting WIMs.
235 Also, security data is now preserved by default.
238 Can now build with older gcc and system headers, like on CentOS 5.
241 Fixed bug that made it impossible to overwrite files in read-write
245 Write byte-order mark before WIM XML data. (imagex.exe requires this to
