1 Only the most important changes more recent than version 0.6 are noted here.
4 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
7 A bug in the interpretation of negative IMAGE indices in the
8 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
9 `wimlib-imagex append' has been fixed.
11 A workaround has been added to successfully apply security descriptors
12 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
15 `wimlib-imagex capture' can now accept the '--delta-from' option
19 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
20 to standard output and applying images from standard input, but they are
21 not compatible with Microsoft's software and are not created by default.
22 See the documentation for --pipable flag of `wimlib-imagex capture' for
25 To better support incremental backups, added support for declaring an
26 image as a modified form of another image. See the documentation for
27 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
30 Added supported for "delta" WIMs. See the documentation for the
31 '--delta-from' option of `wimlib-imagex capture'.
33 The library support for managing split WIMs has been changed to support
34 other arrangements, such as delta WIMs, and be easier to use. This
35 change is visible in `wimlib-imagex', which also can now accept the
36 '--ref' option multiple times, and also now supports "delta" WIMs as
39 wimlib now preserves WIM integrity tables by default, even if
40 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
41 behavior of `wimlib-imagex' whenever the WIM being operated on contains
42 an integrity table and the '--check' option is not specified.
44 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
45 (when --compress is not specified). This provides the best compression
46 ratio by default, which is usually what is desired, at a cost of some
49 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
50 is the command as in `wimlib-imagex COMMAND'; for example, it can be
51 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
52 appropriate hard links are created in UNIX installations of
53 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
54 batch files that emulate this behavior are generated.
56 Security descriptors are now extracted correctly on Windows.
58 Fixed archiving DOS names in NTFS-3g capture mode.
60 The extraction code has been rewritten and it will now be easier to
61 support new features on all supported backends (currently Win32, UNIX,
62 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
63 now supported on all backends, not just UNIX.
65 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
68 wimlib_global_init() now, by default, attempts to acquire additional
69 privileges on Windows, so library clients need not do this.
71 This update bumps the shared library version number up to 9, since it is
72 not binary compatibible with previous releases.
75 Fixed bug in `wimlib-imagex export' that made it impossible to export an
76 image from a WIM that is readonly at the filesystem level.
78 Return error code rather than segfaulting when trying to list files from
79 a non-first part of a split WIM.
81 Joining a WIM will now preserve the RP_FIX and READONLY flags.
84 On Windows, paths given to wimlib-imagex are now treated case
87 Improved behavior regarding invalid filenames; in particular, on
88 Windows, wimlib-imagex will, when extracting, now omit (with an option
89 to override this default) filenames differing only in case, or filenames
90 containing characters not valid on Windows.
92 On Windows, wimlib now supports capturing and extracting long paths
93 (longer than the so-called MAX_PATH).
95 On Windows, `wimlib-imagex update' now acquires proper privileges when
96 running as an Administrator.
98 `wimlib-imagex update' will now complain if no image is specified when
99 trying to update a multi-image WIM.
101 `wimlib-imagex update' now supports specifying a single update command
102 directly on the command line using the --command option.
104 wimlib-imagex will now choose different units for progress messages,
105 depending on the amount of data that needs to be processed.
107 `wimlib-imagex append' will now generate a unique WIM image name if no
108 name is specified and the defaulted name already exists in the WIM.
110 wimlib now allows you to create unnamed WIM images, which can then only
111 be referred to by index.
113 wimlib now allows you to explicitly declare you want write access to a
114 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
117 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
120 Progress callbacks have been added to wimlib's wimlib_update_image()
123 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
124 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
127 NTFS-3g capture now only warns about two conditions previously treated
130 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
133 wimlib now correctly detects and returns an error when reading a WIM
134 image with a cyclic directory structure. (Fun fact: such a WIM will
135 crash Microsoft's software.)
138 Added new "extract" and "update" subcommands to wimlib-imagex, along
139 with associated APIs in the library. These commands are intended mainly
140 for Windows use but can be used on UNIX as well.
142 Many documentation improvements.
144 Fixed a bug in the Windows build where relative symbolic links were not
145 captured in reparse-point fixup mode.
147 Fixed a bug in the Windows build where file handles were left open to
148 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
150 Fixed a bug in the Windows build of wimlib-imagex where globbing
151 split-WIM parts could cause the program to crash.
153 Fixed a bug where the creation time of WIM images would be shown instead
154 of the last modification time.
156 With the Windows build it is now possible to restore a WIM containing
157 symbolic links as a non-Administrator; however you will receive warnings
158 about not being able to extract the symbolic links.
161 Capturing a WIM image should now be significantly faster in most cases
162 due to improved use of the operating system's cache and avoiding reading
163 files twice whenever possible.
165 The Windows build should now work on Windows XP.
167 The Windows build now supports capturing and restoring hidden,
168 compressed, sparse, and encrypted files.
170 The Windows build now supports capturing and applying WIM images from
171 filesystems other than NTFS (with some reduced functionality).
173 The Windows build now extracts short names correctly.
175 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
176 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
177 capture' and `wimlib-imagex apply'.
179 The performance of splitting and joining WIMs should be slightly
182 The LZX and XPRESS compression and decompression functions are now
183 exported from the library.
186 Improvements and bugfixes for the Windows build.
188 Added --strict-acls options.
190 Fixed the way that wimlib determines the order of images in the WIM.
193 Since wimlib can now be used on Windows, wimlib's implementation of
194 ImageX has been renamed to wimlib-imagex to avoid confusion with
195 Microsoft's implementation of ImageX, which would have the same file
196 name ("imagex.exe"). If you really don't like this you can pass the
197 --with-imagex-progname option to `configure' to choose a different name,
198 or even simply rename the binary yourself (but the former way will
199 configure the man pages to use the chosen name).
201 Various bugs fixed in the Windows build. Mainly to do with capturing
202 and restoring alternate data streams correctly in weird cases, and
203 requesting the correct privileges when opening files. Also added the
204 --noacls options to wimlib-imagex capture, append, and apply.
206 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
207 dynamically loaded, so this may make the library compatible with Windows
208 XP (however, there may still be other problems).
211 Added experimental support for native Windows builds. Binaries can be
212 downloaded from the SourceForge page.
214 --source-list option added to `imagex capture' and `imagex append'.
216 Better support for different character encodings.
219 Storing UNIX file owners, groups, and modes in WIM images is now
220 possible using `imagex capture' with the --unix-data flag.
222 Minor bug fixes and documentation fixes.
225 NTFS capture: Fixed capturing duplicate reparse points.
227 NTFS capture: Capture first unnamed stream if there are more than one
228 (print warning instead of error).
230 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
233 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
236 Update to work with ntfs-3g version 2013.1.13.
239 Fixed truncating file to shorter but non-zero length on read-write
242 Various code cleanups and minor documentation fixes.
245 LZX and XPRESS decompression have received some additional optimizations
246 and should now be even faster. (Although, they were already pretty
247 fast--- much faster than typical I/O speeds.)
249 Fixed a bug introduced in v1.2.1 that would cause a directory tree
250 containing hard links to be captured incorrectly in some cases.
253 By default, unmounting a read-write mounted WIM with 'imagex unmount
254 --commit' will now change the WIM in-place without needing to write the
255 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
258 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
259 for a response from the daemon servicing the mounted WIM. Instead,
260 every second 'imagex unmount' will check if the daemon is still alive,
261 and keep waiting if so, otherwise terminate with an error.
263 'imagex unmount --commit' on a read-write mounted WIM will now print
264 progress information regarding the writing of new or modified streams
265 the WIM, just like when capturing or appending a WIM.
267 A small change has been made to XPRESS compression and it should improve
268 the compression ratio slightly.
270 A change was made that may improve performance slightly when applying a
271 WIM image to a NTFS volume.
273 Microsoft has managed to introduce even more bugs into their software,
274 and now the WIMs for Windows 8 have incorrect (too low) reference counts
275 for some streams. This is unsafe because such streams can be removed
276 when they are in actuality still referenced in the WIM (perhaps by a
277 different image). wimlib will now work around this problem by fixing
278 the stream reference counts. This is only done when wimlib_delete_image() is
279 called ('imagex delete') or when wimlib_mount_image() is called with
280 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
281 requires reading the metadata for all images in the WIM, so this will
282 make these operations noticably slower on WIMs with multiple images.
284 Various other bugfixes.
287 Appending images to a WIM is now be done by default without re-building
288 the whole WIM. Use the --rebuild flag to get the old behavior (which
289 was to re-build the entire WIM when a new image is appended).
291 A new command `imagex optimize' is now available to manually re-build a
292 WIM that has wasted space due to repeated appends.
294 Progress information has been improved, and now arbitrary callback
295 functions can be used to show the progress of a WIM operation.
297 A possible bug with changing the bootable image of a WIM was fixed.
299 Some advisory locking is now done to prevent two processes from
300 modifying a WIM at the same time (but only in some cases). For example,
301 you cannot mount two images from a WIM read-write at the same time.
303 Some functions have been reorganized:
304 * wimlib_mount() renamed to wimlib_mount_image().
305 * wimlib_unmount() renamed to wimlib_unmount_image().
306 * wimlib_overwrite_xml_and_header() removed as
307 wimlib_overwrite() suffices now.
308 * wimlib_apply_image_to_ntfs_volume() removed as
309 wimlib_extract_image() suffices now.
310 * wimlib_add_image_from_ntfs_volume() removed as
311 * wimlib_add_image() suffices now.
313 Previously, the soname of libwim.so has been 0.0.0, despite many
314 interface changes. The soname is now updated to 1.0.0 and will now be
315 updated each release.
318 Resources will now be compressed using multiple threads by default.
319 (This applies to `imagex capture', `imagex append', and `imagex
322 Some performance improvements in mounted WIMs.
324 More progress information is shown when capturing a WIM.
327 Lots of minor fixes, code cleanups, and some documentation updates.
328 Nothing in particular is really noteworthy.
331 LZX and XPRESS compression improvements.
333 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
334 Link Bytes of the WIM.
337 Fixed bug when capturing NTFS file with multiple named data streams.
339 Internally, we are now using inode structures, even though these don't
340 appear literally in the WIM file. This simplifies some of the code
341 (mainly for WIM mounting) and likely fixed a few problems, although it
345 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
349 Enough changes to call it version 1.0.0!
351 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
352 to a NTFS volume, is now supported.
354 Hard links and symbolic links have much improved support. They are
355 supported for WIM capture, WIM application, and mounted WIMs (you can
356 even make them on read-write mounted WIMs).
358 Alternate data streams are now supported on mounted WIMs through an
359 xattr or a Windows-style stream interface. Also they are supported when
360 capturing a WIM from NTFS or applying a WIM to NTFS.
362 Split WIMs are better supported. You may now apply an image directly
363 from a split WIM, mount an image from a split WIM read-only, or export
364 an image from a split WIM.
366 Using a capture configuration file is now supported (but not fully yet).
368 SHA1 message digests are checked in more places, so we can make sure
369 applied and captured data is correct.
371 Man pages have been updated and consolidated.
374 Fixed segfault when unmounting read-only WIM.
377 Support for joining and splitting WIMs.
378 Also, security data is now preserved by default.
381 Can now build with older gcc and system headers, like on CentOS 5.
384 Fixed bug that made it impossible to overwrite files in read-write
388 Write byte-order mark before WIM XML data. (imagex.exe requires this to
