1 Only the most important changes more recent than version 0.6 are noted here.
4 Added support for "pipable" WIMs. This support allows capturing images
5 to standard output or applying images from standard input, but they are
6 not compatible with Microsoft's software and are not created by default.
7 See documentation for --pipable flag of `wimlib-imagex capture' for more
8 information. Two new functions have been added to the library to fully
9 support this: wimlib_write_to_fd() and wimlib_extract_image_from_pipe().
11 wimlib now preserve WIM integrity tables by default, even if
12 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This affects
13 wimlib-imagex's behavior when --check is not specified.
15 Security descriptors are now extracted correctly on Windows.
17 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
20 The test suite no longer fails when run in a locale where the decimal
21 separator is not a period.
23 WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed and
24 WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use.
26 The extraction code has been rewritten and it will now be easier to
27 support new features on all supported backends (currently Win32, UNIX,
28 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
29 now supported on all backends, not just UNIX.
31 A few changes were made to the error codes returned by library routines.
34 Fixed bug in `wimlib-imagex export' that made it impossible to export an
35 image from a WIM that is readonly at the filesystem level.
37 Return error code rather than segfaulting when trying to list files from
38 a non-first part of a split WIM.
40 Joining a WIM will now preserve the RP_FIX and READONLY flags.
43 On Windows, paths given to wimlib-imagex are now treated case
46 Improved behavior regarding invalid filenames; in particular, on
47 Windows, wimlib-imagex will, when extracting, now omit (with an option
48 to override this default) filenames differing only in case, or filenames
49 containing characters not valid on Windows.
51 On Windows, wimlib now supports capturing and extracting long paths
52 (longer than the so-called MAX_PATH).
54 On Windows, `wimlib-imagex update' now acquires proper privileges when
55 running as an Administrator.
57 `wimlib-imagex update' will now complain if no image is specified when
58 trying to update a multi-image WIM.
60 `wimlib-imagex update' now supports specifying a single update command
61 directly on the command line using the --command option.
63 wimlib-imagex will now choose different units for progress messages,
64 depending on the amount of data that needs to be processed.
66 `wimlib-imagex append' will now generate a unique WIM image name if no
67 name is specified and the defaulted name already exists in the WIM.
69 wimlib now allows you to create unnamed WIM images, which can then only
70 be referred to by index.
72 wimlib now allows you to explicitly declare you want write access to a
73 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
76 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
79 Progress callbacks have been added to wimlib's wimlib_update_image()
82 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
83 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
86 NTFS-3g capture now only warns about two conditions previously treated
89 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
92 wimlib now correctly detects and returns an error when reading a WIM
93 image with a cyclic directory structure. (Fun fact: such a WIM will
94 crash Microsoft's software.)
97 Added new "extract" and "update" subcommands to wimlib-imagex, along
98 with associated APIs in the library. These commands are intended mainly
99 for Windows use but can be used on UNIX as well.
101 Many documentation improvements.
103 Fixed a bug in the Windows build where relative symbolic links were not
104 captured in reparse-point fixup mode.
106 Fixed a bug in the Windows build where file handles were left open to
107 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
109 Fixed a bug in the Windows build of wimlib-imagex where globbing
110 split-WIM parts could cause the program to crash.
112 Fixed a bug where the creation time of WIM images would be shown instead
113 of the last modification time.
115 With the Windows build it is now possible to restore a WIM containing
116 symbolic links as a non-Administrator; however you will receive warnings
117 about not being able to extract the symbolic links.
120 Capturing a WIM image should now be significantly faster in most cases
121 due to improved use of the operating system's cache and avoiding reading
122 files twice whenever possible.
124 The Windows build should now work on Windows XP.
126 The Windows build now supports capturing and restoring hidden,
127 compressed, sparse, and encrypted files.
129 The Windows build now supports capturing and applying WIM images from
130 filesystems other than NTFS (with some reduced functionality).
132 The Windows build now extracts short names correctly.
134 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
135 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
136 capture' and `wimlib-imagex apply'.
138 The performance of splitting and joining WIMs should be slightly
141 The LZX and XPRESS compression and decompression functions are now
142 exported from the library.
145 Improvements and bugfixes for the Windows build.
147 Added --strict-acls options.
149 Fixed the way that wimlib determines the order of images in the WIM.
152 Since wimlib can now be used on Windows, wimlib's implementation of
153 ImageX has been renamed to wimlib-imagex to avoid confusion with
154 Microsoft's implementation of ImageX, which would have the same file
155 name ("imagex.exe"). If you really don't like this you can pass the
156 --with-imagex-progname option to `configure' to choose a different name,
157 or even simply rename the binary yourself (but the former way will
158 configure the man pages to use the chosen name).
160 Various bugs fixed in the Windows build. Mainly to do with capturing
161 and restoring alternate data streams correctly in weird cases, and
162 requesting the correct privileges when opening files. Also added the
163 --noacls options to wimlib-imagex capture, append, and apply.
165 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
166 dynamically loaded, so this may make the library compatible with Windows
167 XP (however, there may still be other problems).
170 Added experimental support for native Windows builds. Binaries can be
171 downloaded from the SourceForge page.
173 --source-list option added to `imagex capture' and `imagex append'.
175 Better support for different character encodings.
178 Storing UNIX file owners, groups, and modes in WIM images is now
179 possible using `imagex capture' with the --unix-data flag.
181 Minor bug fixes and documentation fixes.
184 NTFS capture: Fixed capturing duplicate reparse points.
186 NTFS capture: Capture first unnamed stream if there are more than one
187 (print warning instead of error).
189 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
192 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
195 Update to work with ntfs-3g version 2013.1.13.
198 Fixed truncating file to shorter but non-zero length on read-write
201 Various code cleanups and minor documentation fixes.
204 LZX and XPRESS decompression have received some additional optimizations
205 and should now be even faster. (Although, they were already pretty
206 fast--- much faster than typical I/O speeds.)
208 Fixed a bug introduced in v1.2.1 that would cause a directory tree
209 containing hard links to be captured incorrectly in some cases.
212 By default, unmounting a read-write mounted WIM with 'imagex unmount
213 --commit' will now change the WIM in-place without needing to write the
214 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
217 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
218 for a response from the daemon servicing the mounted WIM. Instead,
219 every second 'imagex unmount' will check if the daemon is still alive,
220 and keep waiting if so, otherwise terminate with an error.
222 'imagex unmount --commit' on a read-write mounted WIM will now print
223 progress information regarding the writing of new or modified streams
224 the WIM, just like when capturing or appending a WIM.
226 A small change has been made to XPRESS compression and it should improve
227 the compression ratio slightly.
229 A change was made that may improve performance slightly when applying a
230 WIM image to a NTFS volume.
232 Microsoft has managed to introduce even more bugs into their software,
233 and now the WIMs for Windows 8 have incorrect (too low) reference counts
234 for some streams. This is unsafe because such streams can be removed
235 when they are in actuality still referenced in the WIM (perhaps by a
236 different image). wimlib will now work around this problem by fixing
237 the stream reference counts. This is only done when wimlib_delete_image() is
238 called ('imagex delete') or when wimlib_mount_image() is called with
239 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
240 requires reading the metadata for all images in the WIM, so this will
241 make these operations noticably slower on WIMs with multiple images.
243 Various other bugfixes.
246 Appending images to a WIM is now be done by default without re-building
247 the whole WIM. Use the --rebuild flag to get the old behavior (which
248 was to re-build the entire WIM when a new image is appended).
250 A new command `imagex optimize' is now available to manually re-build a
251 WIM that has wasted space due to repeated appends.
253 Progress information has been improved, and now arbitrary callback
254 functions can be used to show the progress of a WIM operation.
256 A possible bug with changing the bootable image of a WIM was fixed.
258 Some advisory locking is now done to prevent two processes from
259 modifying a WIM at the same time (but only in some cases). For example,
260 you cannot mount two images from a WIM read-write at the same time.
262 Some functions have been reorganized:
263 * wimlib_mount() renamed to wimlib_mount_image().
264 * wimlib_unmount() renamed to wimlib_unmount_image().
265 * wimlib_overwrite_xml_and_header() removed as
266 wimlib_overwrite() suffices now.
267 * wimlib_apply_image_to_ntfs_volume() removed as
268 wimlib_extract_image() suffices now.
269 * wimlib_add_image_from_ntfs_volume() removed as
270 * wimlib_add_image() suffices now.
272 Previously, the soname of libwim.so has been 0.0.0, despite many
273 interface changes. The soname is now updated to 1.0.0 and will now be
274 updated each release.
277 Resources will now be compressed using multiple threads by default.
278 (This applies to `imagex capture', `imagex append', and `imagex
281 Some performance improvements in mounted WIMs.
283 More progress information is shown when capturing a WIM.
286 Lots of minor fixes, code cleanups, and some documentation updates.
287 Nothing in particular is really noteworthy.
290 LZX and XPRESS compression improvements.
292 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
293 Link Bytes of the WIM.
296 Fixed bug when capturing NTFS file with multiple named data streams.
298 Internally, we are now using inode structures, even though these don't
299 appear literally in the WIM file. This simplifies some of the code
300 (mainly for WIM mounting) and likely fixed a few problems, although it
304 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
308 Enough changes to call it version 1.0.0!
310 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
311 to a NTFS volume, is now supported.
313 Hard links and symbolic links have much improved support. They are
314 supported for WIM capture, WIM application, and mounted WIMs (you can
315 even make them on read-write mounted WIMs).
317 Alternate data streams are now supported on mounted WIMs through an
318 xattr or a Windows-style stream interface. Also they are supported when
319 capturing a WIM from NTFS or applying a WIM to NTFS.
321 Split WIMs are better supported. You may now apply an image directly
322 from a split WIM, mount an image from a split WIM read-only, or export
323 an image from a split WIM.
325 Using a capture configuration file is now supported (but not fully yet).
327 SHA1 message digests are checked in more places, so we can make sure
328 applied and captured data is correct.
330 Man pages have been updated and consolidated.
333 Fixed segfault when unmounting read-only WIM.
336 Support for joining and splitting WIMs.
337 Also, security data is now preserved by default.
340 Can now build with older gcc and system headers, like on CentOS 5.
343 Fixed bug that made it impossible to overwrite files in read-write
347 Write byte-order mark before WIM XML data. (imagex.exe requires this to
