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