1 Only the most important changes more recent than version 0.6 are noted here.
4 On Windows, paths given to wimlib-imagex are now treated case
7 Improved behavior regarding invalid filenames; in particular, on
8 Windows, wimlib-imagex will, when extracting, now omit (with an option
9 to override this default) filenames differing only in case, or filenames
10 containing characters not valid on Windows.
12 On Windows, wimlib now supports capturing and extracting long paths
13 (longer than the so-called MAX_PATH).
15 On Windows, `wimlib-imagex update' now acquires proper privileges when
16 running as an Administrator.
18 `wimlib-imagex update' will now complain if no image is specified when
19 trying to update a multi-image WIM.
21 `wimlib-imagex update' now supports specifying a single update command
22 directly on the command line using the --command option.
24 wimlib-imagex will now choose different units for progress messages,
25 depending on the amount of data that needs to be processed.
28 Added new "extract" and "update" subcommands to wimlib-imagex, along
29 with associated APIs in the library. These commands are intended mainly
30 for Windows use but can be used on UNIX as well.
32 Many documentation improvements.
34 Fixed a bug in the Windows build where relative symbolic links were not
35 captured in reparse-point fixup mode.
37 Fixed a bug in the Windows build where file handles were left open to
38 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
40 Fixed a bug in the Windows build of wimlib-imagex where globbing
41 split-WIM parts could cause the program to crash.
43 Fixed a bug where the creation time of WIM images would be shown instead
44 of the last modification time.
46 With the Windows build it is now possible to restore a WIM containing
47 symbolic links as a non-Administrator; however you will receive warnings
48 about not being able to extract the symbolic links.
51 Capturing a WIM image should now be significantly faster in most cases
52 due to improved use of the operating system's cache and avoiding reading
53 files twice whenever possible.
55 The Windows build should now work on Windows XP.
57 The Windows build now supports capturing and restoring hidden,
58 compressed, sparse, and encrypted files.
60 The Windows build now supports capturing and applying WIM images from
61 filesystems other than NTFS (with some reduced functionality).
63 The Windows build now extracts short names correctly.
65 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
66 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
67 capture' and `wimlib-imagex apply'.
69 The performance of splitting and joining WIMs should be slightly
72 The LZX and XPRESS compression and decompression functions are now
73 exported from the library.
76 Improvements and bugfixes for the Windows build.
78 Added --strict-acls options.
80 Fixed the way that wimlib determines the order of images in the WIM.
83 Since wimlib can now be used on Windows, wimlib's implementation of
84 ImageX has been renamed to wimlib-imagex to avoid confusion with
85 Microsoft's implementation of ImageX, which would have the same file
86 name ("imagex.exe"). If you really don't like this you can pass the
87 --with-imagex-progname option to `configure' to choose a different name,
88 or even simply rename the binary yourself (but the former way will
89 configure the man pages to use the chosen name).
91 Various bugs fixed in the Windows build. Mainly to do with capturing
92 and restoring alternate data streams correctly in weird cases, and
93 requesting the correct privileges when opening files. Also added the
94 --noacls options to wimlib-imagex capture, append, and apply.
96 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
97 dynamically loaded, so this may make the library compatible with Windows
98 XP (however, there may still be other problems).
101 Added experimental support for native Windows builds. Binaries can be
102 downloaded from the SourceForge page.
104 --source-list option added to `imagex capture' and `imagex append'.
106 Better support for different character encodings.
109 Storing UNIX file owners, groups, and modes in WIM images is now
110 possible using `imagex capture' with the --unix-data flag.
112 Minor bug fixes and documentation fixes.
115 NTFS capture: Fixed capturing duplicate reparse points.
117 NTFS capture: Capture first unnamed stream if there are more than one
118 (print warning instead of error).
120 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
123 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
126 Update to work with ntfs-3g version 2013.1.13.
129 Fixed truncating file to shorter but non-zero length on read-write
132 Various code cleanups and minor documentation fixes.
135 LZX and XPRESS decompression have received some additional optimizations
136 and should now be even faster. (Although, they were already pretty
137 fast--- much faster than typical I/O speeds.)
139 Fixed a bug introduced in v1.2.1 that would cause a directory tree
140 containing hard links to be captured incorrectly in some cases.
143 By default, unmounting a read-write mounted WIM with 'imagex unmount
144 --commit' will now change the WIM in-place without needing to write the
145 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
148 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
149 for a response from the daemon servicing the mounted WIM. Instead,
150 every second 'imagex unmount' will check if the daemon is still alive,
151 and keep waiting if so, otherwise terminate with an error.
153 'imagex unmount --commit' on a read-write mounted WIM will now print
154 progress information regarding the writing of new or modified streams
155 the WIM, just like when capturing or appending a WIM.
157 A small change has been made to XPRESS compression and it should improve
158 the compression ratio slightly.
160 A change was made that may improve performance slightly when applying a
161 WIM image to a NTFS volume.
163 Microsoft has managed to introduce even more bugs into their software,
164 and now the WIMs for Windows 8 have incorrect (too low) reference counts
165 for some streams. This is unsafe because such streams can be removed
166 when they are in actuality still referenced in the WIM (perhaps by a
167 different image). wimlib will now work around this problem by fixing
168 the stream reference counts. This is only done when wimlib_delete_image() is
169 called ('imagex delete') or when wimlib_mount_image() is called with
170 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
171 requires reading the metadata for all images in the WIM, so this will
172 make these operations noticably slower on WIMs with multiple images.
174 Various other bugfixes.
177 Appending images to a WIM is now be done by default without re-building
178 the whole WIM. Use the --rebuild flag to get the old behavior (which
179 was to re-build the entire WIM when a new image is appended).
181 A new command `imagex optimize' is now available to manually re-build a
182 WIM that has wasted space due to repeated appends.
184 Progress information has been improved, and now arbitrary callback
185 functions can be used to show the progress of a WIM operation.
187 A possible bug with changing the bootable image of a WIM was fixed.
189 Some advisory locking is now done to prevent two processes from
190 modifying a WIM at the same time (but only in some cases). For example,
191 you cannot mount two images from a WIM read-write at the same time.
193 Some functions have been reorganized:
194 * wimlib_mount() renamed to wimlib_mount_image().
195 * wimlib_unmount() renamed to wimlib_unmount_image().
196 * wimlib_overwrite_xml_and_header() removed as
197 wimlib_overwrite() suffices now.
198 * wimlib_apply_image_to_ntfs_volume() removed as
199 wimlib_extract_image() suffices now.
200 * wimlib_add_image_from_ntfs_volume() removed as
201 * wimlib_add_image() suffices now.
203 Previously, the soname of libwim.so has been 0.0.0, despite many
204 interface changes. The soname is now updated to 1.0.0 and will now be
205 updated each release.
208 Resources will now be compressed using multiple threads by default.
209 (This applies to `imagex capture', `imagex append', and `imagex
212 Some performance improvements in mounted WIMs.
214 More progress information is shown when capturing a WIM.
217 Lots of minor fixes, code cleanups, and some documentation updates.
218 Nothing in particular is really noteworthy.
221 LZX and XPRESS compression improvements.
223 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
224 Link Bytes of the WIM.
227 Fixed bug when capturing NTFS file with multiple named data streams.
229 Internally, we are now using inode structures, even though these don't
230 appear literally in the WIM file. This simplifies some of the code
231 (mainly for WIM mounting) and likely fixed a few problems, although it
235 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
239 Enough changes to call it version 1.0.0!
241 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
242 to a NTFS volume, is now supported.
244 Hard links and symbolic links have much improved support. They are
245 supported for WIM capture, WIM application, and mounted WIMs (you can
246 even make them on read-write mounted WIMs).
248 Alternate data streams are now supported on mounted WIMs through an
249 xattr or a Windows-style stream interface. Also they are supported when
250 capturing a WIM from NTFS or applying a WIM to NTFS.
252 Split WIMs are better supported. You may now apply an image directly
253 from a split WIM, mount an image from a split WIM read-only, or export
254 an image from a split WIM.
256 Using a capture configuration file is now supported (but not fully yet).
258 SHA1 message digests are checked in more places, so we can make sure
259 applied and captured data is correct.
261 Man pages have been updated and consolidated.
264 Fixed segfault when unmounting read-only WIM.
267 Support for joining and splitting WIMs.
268 Also, security data is now preserved by default.
271 Can now build with older gcc and system headers, like on CentOS 5.
274 Fixed bug that made it impossible to overwrite files in read-write
278 Write byte-order mark before WIM XML data. (imagex.exe requires this to
