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.
27 `wimlib-imagex append' will now generate a unique WIM image name if no
28 name is specified and the defaulted name already exists in the WIM.
30 wimlib now allows you to create unnamed WIM images, which can then only
31 be referred to by index.
33 wimlib now allows you to explicitly declare you want write access to a
34 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
37 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
40 Progress callbacks have been added to wimlib's wimlib_update_image()
43 NTFS-3g capture now only warns about two conditions previously treated
46 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
49 wimlib now correctly detects and returns an error when reading a WIM
50 image with a cyclic directory structure. (Fun fact: such a WIM will
51 crash Microsoft's software.)
54 Added new "extract" and "update" subcommands to wimlib-imagex, along
55 with associated APIs in the library. These commands are intended mainly
56 for Windows use but can be used on UNIX as well.
58 Many documentation improvements.
60 Fixed a bug in the Windows build where relative symbolic links were not
61 captured in reparse-point fixup mode.
63 Fixed a bug in the Windows build where file handles were left open to
64 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
66 Fixed a bug in the Windows build of wimlib-imagex where globbing
67 split-WIM parts could cause the program to crash.
69 Fixed a bug where the creation time of WIM images would be shown instead
70 of the last modification time.
72 With the Windows build it is now possible to restore a WIM containing
73 symbolic links as a non-Administrator; however you will receive warnings
74 about not being able to extract the symbolic links.
77 Capturing a WIM image should now be significantly faster in most cases
78 due to improved use of the operating system's cache and avoiding reading
79 files twice whenever possible.
81 The Windows build should now work on Windows XP.
83 The Windows build now supports capturing and restoring hidden,
84 compressed, sparse, and encrypted files.
86 The Windows build now supports capturing and applying WIM images from
87 filesystems other than NTFS (with some reduced functionality).
89 The Windows build now extracts short names correctly.
91 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
92 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
93 capture' and `wimlib-imagex apply'.
95 The performance of splitting and joining WIMs should be slightly
98 The LZX and XPRESS compression and decompression functions are now
99 exported from the library.
102 Improvements and bugfixes for the Windows build.
104 Added --strict-acls options.
106 Fixed the way that wimlib determines the order of images in the WIM.
109 Since wimlib can now be used on Windows, wimlib's implementation of
110 ImageX has been renamed to wimlib-imagex to avoid confusion with
111 Microsoft's implementation of ImageX, which would have the same file
112 name ("imagex.exe"). If you really don't like this you can pass the
113 --with-imagex-progname option to `configure' to choose a different name,
114 or even simply rename the binary yourself (but the former way will
115 configure the man pages to use the chosen name).
117 Various bugs fixed in the Windows build. Mainly to do with capturing
118 and restoring alternate data streams correctly in weird cases, and
119 requesting the correct privileges when opening files. Also added the
120 --noacls options to wimlib-imagex capture, append, and apply.
122 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
123 dynamically loaded, so this may make the library compatible with Windows
124 XP (however, there may still be other problems).
127 Added experimental support for native Windows builds. Binaries can be
128 downloaded from the SourceForge page.
130 --source-list option added to `imagex capture' and `imagex append'.
132 Better support for different character encodings.
135 Storing UNIX file owners, groups, and modes in WIM images is now
136 possible using `imagex capture' with the --unix-data flag.
138 Minor bug fixes and documentation fixes.
141 NTFS capture: Fixed capturing duplicate reparse points.
143 NTFS capture: Capture first unnamed stream if there are more than one
144 (print warning instead of error).
146 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
149 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
152 Update to work with ntfs-3g version 2013.1.13.
155 Fixed truncating file to shorter but non-zero length on read-write
158 Various code cleanups and minor documentation fixes.
161 LZX and XPRESS decompression have received some additional optimizations
162 and should now be even faster. (Although, they were already pretty
163 fast--- much faster than typical I/O speeds.)
165 Fixed a bug introduced in v1.2.1 that would cause a directory tree
166 containing hard links to be captured incorrectly in some cases.
169 By default, unmounting a read-write mounted WIM with 'imagex unmount
170 --commit' will now change the WIM in-place without needing to write the
171 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
174 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
175 for a response from the daemon servicing the mounted WIM. Instead,
176 every second 'imagex unmount' will check if the daemon is still alive,
177 and keep waiting if so, otherwise terminate with an error.
179 'imagex unmount --commit' on a read-write mounted WIM will now print
180 progress information regarding the writing of new or modified streams
181 the WIM, just like when capturing or appending a WIM.
183 A small change has been made to XPRESS compression and it should improve
184 the compression ratio slightly.
186 A change was made that may improve performance slightly when applying a
187 WIM image to a NTFS volume.
189 Microsoft has managed to introduce even more bugs into their software,
190 and now the WIMs for Windows 8 have incorrect (too low) reference counts
191 for some streams. This is unsafe because such streams can be removed
192 when they are in actuality still referenced in the WIM (perhaps by a
193 different image). wimlib will now work around this problem by fixing
194 the stream reference counts. This is only done when wimlib_delete_image() is
195 called ('imagex delete') or when wimlib_mount_image() is called with
196 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
197 requires reading the metadata for all images in the WIM, so this will
198 make these operations noticably slower on WIMs with multiple images.
200 Various other bugfixes.
203 Appending images to a WIM is now be done by default without re-building
204 the whole WIM. Use the --rebuild flag to get the old behavior (which
205 was to re-build the entire WIM when a new image is appended).
207 A new command `imagex optimize' is now available to manually re-build a
208 WIM that has wasted space due to repeated appends.
210 Progress information has been improved, and now arbitrary callback
211 functions can be used to show the progress of a WIM operation.
213 A possible bug with changing the bootable image of a WIM was fixed.
215 Some advisory locking is now done to prevent two processes from
216 modifying a WIM at the same time (but only in some cases). For example,
217 you cannot mount two images from a WIM read-write at the same time.
219 Some functions have been reorganized:
220 * wimlib_mount() renamed to wimlib_mount_image().
221 * wimlib_unmount() renamed to wimlib_unmount_image().
222 * wimlib_overwrite_xml_and_header() removed as
223 wimlib_overwrite() suffices now.
224 * wimlib_apply_image_to_ntfs_volume() removed as
225 wimlib_extract_image() suffices now.
226 * wimlib_add_image_from_ntfs_volume() removed as
227 * wimlib_add_image() suffices now.
229 Previously, the soname of libwim.so has been 0.0.0, despite many
230 interface changes. The soname is now updated to 1.0.0 and will now be
231 updated each release.
234 Resources will now be compressed using multiple threads by default.
235 (This applies to `imagex capture', `imagex append', and `imagex
238 Some performance improvements in mounted WIMs.
240 More progress information is shown when capturing a WIM.
243 Lots of minor fixes, code cleanups, and some documentation updates.
244 Nothing in particular is really noteworthy.
247 LZX and XPRESS compression improvements.
249 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
250 Link Bytes of the WIM.
253 Fixed bug when capturing NTFS file with multiple named data streams.
255 Internally, we are now using inode structures, even though these don't
256 appear literally in the WIM file. This simplifies some of the code
257 (mainly for WIM mounting) and likely fixed a few problems, although it
261 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
265 Enough changes to call it version 1.0.0!
267 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
268 to a NTFS volume, is now supported.
270 Hard links and symbolic links have much improved support. They are
271 supported for WIM capture, WIM application, and mounted WIMs (you can
272 even make them on read-write mounted WIMs).
274 Alternate data streams are now supported on mounted WIMs through an
275 xattr or a Windows-style stream interface. Also they are supported when
276 capturing a WIM from NTFS or applying a WIM to NTFS.
278 Split WIMs are better supported. You may now apply an image directly
279 from a split WIM, mount an image from a split WIM read-only, or export
280 an image from a split WIM.
282 Using a capture configuration file is now supported (but not fully yet).
284 SHA1 message digests are checked in more places, so we can make sure
285 applied and captured data is correct.
287 Man pages have been updated and consolidated.
290 Fixed segfault when unmounting read-only WIM.
293 Support for joining and splitting WIMs.
294 Also, security data is now preserved by default.
297 Can now build with older gcc and system headers, like on CentOS 5.
300 Fixed bug that made it impossible to overwrite files in read-write
304 Write byte-order mark before WIM XML data. (imagex.exe requires this to
