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