1 Only the most important changes more recent than version 0.6 are noted here.
4 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
5 to standard output and applying images from standard input, but they are
6 not compatible with Microsoft's software and are not created by default.
7 See the documentation for --pipable flag of `wimlib-imagex capture' for
8 more information. Two new functions have been added to the library to
9 fully support this: wimlib_write_to_fd() and
10 wimlib_extract_image_from_pipe().
12 wimlib now preserve WIM integrity tables by default, even if
13 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
14 behavior of `wimlib-imagex' whenever the WIM being operated on contains
15 an integrity table and the '--check' option is not specified.
17 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
18 (when --compress is not specified). This provides the best compression
19 ratio by default, which is usually what is desired, at a cost of some
22 For convenience, `wimlib-imagex' now supports being invoked as
23 wimCOMMAND, where COMMAND is the command as in `wimlib-imagex COMMAND';
24 for example, it can be invoked as `wimapply' as an alternative to
25 `wimlib-imagex apply'. The appropriate hard links are created in UNIX
26 installations of `wimlib-imagex', while for the Windows distribution of
27 `wimlib-imagex', batch files that emulate this behavior are generated.
29 `wimlib-imagex' no longer recognizes the 'mount', 'mountrw', and
30 'unmount' commands on Windows, since they didn't work on Windows anyway.
32 Security descriptors are now extracted correctly on Windows.
34 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
37 The test suite no longer fails when run in a locale where the decimal
38 separator is not a period.
40 From the library, WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed
41 and WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use. Also,
42 WIMLIB_PROGRESS_MSG_JOIN_STREAMS has been removed, but
43 WIMLIB_PROGRESS_MSG_WRITE_STREAMS will be received instead and now
44 provides WIM part numbers.
46 The extraction code has been rewritten and it will now be easier to
47 support new features on all supported backends (currently Win32, UNIX,
48 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
49 now supported on all backends, not just UNIX.
51 The LZX compression and decompression code now compiles correctly on the
52 ARM architecture (where 'char' is unsigned).
54 wimlib_split() progress messages now report the total number of parts
57 A few changes were made to the error codes returned by library routines.
59 To make wimlib easier to use on Windows, wimlib_global_init() now
60 automatically attempts to acquire additional privileges on Windows, so
61 library clients need not do this (although they can provide a flag to
62 get the old behavior and manage privileges themselves).
64 This update bumps the shared library version number up to 9, since it
65 doesn't quite maintain binary compatibility with previous releases.
68 Fixed bug in `wimlib-imagex export' that made it impossible to export an
69 image from a WIM that is readonly at the filesystem level.
71 Return error code rather than segfaulting when trying to list files from
72 a non-first part of a split WIM.
74 Joining a WIM will now preserve the RP_FIX and READONLY flags.
77 On Windows, paths given to wimlib-imagex are now treated case
80 Improved behavior regarding invalid filenames; in particular, on
81 Windows, wimlib-imagex will, when extracting, now omit (with an option
82 to override this default) filenames differing only in case, or filenames
83 containing characters not valid on Windows.
85 On Windows, wimlib now supports capturing and extracting long paths
86 (longer than the so-called MAX_PATH).
88 On Windows, `wimlib-imagex update' now acquires proper privileges when
89 running as an Administrator.
91 `wimlib-imagex update' will now complain if no image is specified when
92 trying to update a multi-image WIM.
94 `wimlib-imagex update' now supports specifying a single update command
95 directly on the command line using the --command option.
97 wimlib-imagex will now choose different units for progress messages,
98 depending on the amount of data that needs to be processed.
100 `wimlib-imagex append' will now generate a unique WIM image name if no
101 name is specified and the defaulted name already exists in the WIM.
103 wimlib now allows you to create unnamed WIM images, which can then only
104 be referred to by index.
106 wimlib now allows you to explicitly declare you want write access to a
107 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
110 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
113 Progress callbacks have been added to wimlib's wimlib_update_image()
116 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
117 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
120 NTFS-3g capture now only warns about two conditions previously treated
123 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
126 wimlib now correctly detects and returns an error when reading a WIM
127 image with a cyclic directory structure. (Fun fact: such a WIM will
128 crash Microsoft's software.)
131 Added new "extract" and "update" subcommands to wimlib-imagex, along
132 with associated APIs in the library. These commands are intended mainly
133 for Windows use but can be used on UNIX as well.
135 Many documentation improvements.
137 Fixed a bug in the Windows build where relative symbolic links were not
138 captured in reparse-point fixup mode.
140 Fixed a bug in the Windows build where file handles were left open to
141 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
143 Fixed a bug in the Windows build of wimlib-imagex where globbing
144 split-WIM parts could cause the program to crash.
146 Fixed a bug where the creation time of WIM images would be shown instead
147 of the last modification time.
149 With the Windows build it is now possible to restore a WIM containing
150 symbolic links as a non-Administrator; however you will receive warnings
151 about not being able to extract the symbolic links.
154 Capturing a WIM image should now be significantly faster in most cases
155 due to improved use of the operating system's cache and avoiding reading
156 files twice whenever possible.
158 The Windows build should now work on Windows XP.
160 The Windows build now supports capturing and restoring hidden,
161 compressed, sparse, and encrypted files.
163 The Windows build now supports capturing and applying WIM images from
164 filesystems other than NTFS (with some reduced functionality).
166 The Windows build now extracts short names correctly.
168 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
169 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
170 capture' and `wimlib-imagex apply'.
172 The performance of splitting and joining WIMs should be slightly
175 The LZX and XPRESS compression and decompression functions are now
176 exported from the library.
179 Improvements and bugfixes for the Windows build.
181 Added --strict-acls options.
183 Fixed the way that wimlib determines the order of images in the WIM.
186 Since wimlib can now be used on Windows, wimlib's implementation of
187 ImageX has been renamed to wimlib-imagex to avoid confusion with
188 Microsoft's implementation of ImageX, which would have the same file
189 name ("imagex.exe"). If you really don't like this you can pass the
190 --with-imagex-progname option to `configure' to choose a different name,
191 or even simply rename the binary yourself (but the former way will
192 configure the man pages to use the chosen name).
194 Various bugs fixed in the Windows build. Mainly to do with capturing
195 and restoring alternate data streams correctly in weird cases, and
196 requesting the correct privileges when opening files. Also added the
197 --noacls options to wimlib-imagex capture, append, and apply.
199 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
200 dynamically loaded, so this may make the library compatible with Windows
201 XP (however, there may still be other problems).
204 Added experimental support for native Windows builds. Binaries can be
205 downloaded from the SourceForge page.
207 --source-list option added to `imagex capture' and `imagex append'.
209 Better support for different character encodings.
212 Storing UNIX file owners, groups, and modes in WIM images is now
213 possible using `imagex capture' with the --unix-data flag.
215 Minor bug fixes and documentation fixes.
218 NTFS capture: Fixed capturing duplicate reparse points.
220 NTFS capture: Capture first unnamed stream if there are more than one
221 (print warning instead of error).
223 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
226 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
229 Update to work with ntfs-3g version 2013.1.13.
232 Fixed truncating file to shorter but non-zero length on read-write
235 Various code cleanups and minor documentation fixes.
238 LZX and XPRESS decompression have received some additional optimizations
239 and should now be even faster. (Although, they were already pretty
240 fast--- much faster than typical I/O speeds.)
242 Fixed a bug introduced in v1.2.1 that would cause a directory tree
243 containing hard links to be captured incorrectly in some cases.
246 By default, unmounting a read-write mounted WIM with 'imagex unmount
247 --commit' will now change the WIM in-place without needing to write the
248 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
251 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
252 for a response from the daemon servicing the mounted WIM. Instead,
253 every second 'imagex unmount' will check if the daemon is still alive,
254 and keep waiting if so, otherwise terminate with an error.
256 'imagex unmount --commit' on a read-write mounted WIM will now print
257 progress information regarding the writing of new or modified streams
258 the WIM, just like when capturing or appending a WIM.
260 A small change has been made to XPRESS compression and it should improve
261 the compression ratio slightly.
263 A change was made that may improve performance slightly when applying a
264 WIM image to a NTFS volume.
266 Microsoft has managed to introduce even more bugs into their software,
267 and now the WIMs for Windows 8 have incorrect (too low) reference counts
268 for some streams. This is unsafe because such streams can be removed
269 when they are in actuality still referenced in the WIM (perhaps by a
270 different image). wimlib will now work around this problem by fixing
271 the stream reference counts. This is only done when wimlib_delete_image() is
272 called ('imagex delete') or when wimlib_mount_image() is called with
273 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
274 requires reading the metadata for all images in the WIM, so this will
275 make these operations noticably slower on WIMs with multiple images.
277 Various other bugfixes.
280 Appending images to a WIM is now be done by default without re-building
281 the whole WIM. Use the --rebuild flag to get the old behavior (which
282 was to re-build the entire WIM when a new image is appended).
284 A new command `imagex optimize' is now available to manually re-build a
285 WIM that has wasted space due to repeated appends.
287 Progress information has been improved, and now arbitrary callback
288 functions can be used to show the progress of a WIM operation.
290 A possible bug with changing the bootable image of a WIM was fixed.
292 Some advisory locking is now done to prevent two processes from
293 modifying a WIM at the same time (but only in some cases). For example,
294 you cannot mount two images from a WIM read-write at the same time.
296 Some functions have been reorganized:
297 * wimlib_mount() renamed to wimlib_mount_image().
298 * wimlib_unmount() renamed to wimlib_unmount_image().
299 * wimlib_overwrite_xml_and_header() removed as
300 wimlib_overwrite() suffices now.
301 * wimlib_apply_image_to_ntfs_volume() removed as
302 wimlib_extract_image() suffices now.
303 * wimlib_add_image_from_ntfs_volume() removed as
304 * wimlib_add_image() suffices now.
306 Previously, the soname of libwim.so has been 0.0.0, despite many
307 interface changes. The soname is now updated to 1.0.0 and will now be
308 updated each release.
311 Resources will now be compressed using multiple threads by default.
312 (This applies to `imagex capture', `imagex append', and `imagex
315 Some performance improvements in mounted WIMs.
317 More progress information is shown when capturing a WIM.
320 Lots of minor fixes, code cleanups, and some documentation updates.
321 Nothing in particular is really noteworthy.
324 LZX and XPRESS compression improvements.
326 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
327 Link Bytes of the WIM.
330 Fixed bug when capturing NTFS file with multiple named data streams.
332 Internally, we are now using inode structures, even though these don't
333 appear literally in the WIM file. This simplifies some of the code
334 (mainly for WIM mounting) and likely fixed a few problems, although it
338 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
342 Enough changes to call it version 1.0.0!
344 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
345 to a NTFS volume, is now supported.
347 Hard links and symbolic links have much improved support. They are
348 supported for WIM capture, WIM application, and mounted WIMs (you can
349 even make them on read-write mounted WIMs).
351 Alternate data streams are now supported on mounted WIMs through an
352 xattr or a Windows-style stream interface. Also they are supported when
353 capturing a WIM from NTFS or applying a WIM to NTFS.
355 Split WIMs are better supported. You may now apply an image directly
356 from a split WIM, mount an image from a split WIM read-only, or export
357 an image from a split WIM.
359 Using a capture configuration file is now supported (but not fully yet).
361 SHA1 message digests are checked in more places, so we can make sure
362 applied and captured data is correct.
364 Man pages have been updated and consolidated.
367 Fixed segfault when unmounting read-only WIM.
370 Support for joining and splitting WIMs.
371 Also, security data is now preserved by default.
374 Can now build with older gcc and system headers, like on CentOS 5.
377 Fixed bug that made it impossible to overwrite files in read-write
381 Write byte-order mark before WIM XML data. (imagex.exe requires this to
