1 Only the most important changes more recent than version 0.6 are noted here.
4 Paths given to wimlib-imagex on Windows 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 `wimlib-imagex update' now acquires proper privileges on Windows when
13 running as an Administrator.
15 `wimlib-imagex update' will now complain if no image is specified when
16 trying to update a multi-image WIM.
18 wimlib-imagex will now choose different units for progress messages,
19 depending on the amount of data that needs to be processed.
22 Added new "extract" and "update" subcommands to wimlib-imagex, along
23 with associated APIs in the library. These commands are intended mainly
24 for Windows use but can be used on UNIX as well.
26 Many documentation improvements.
28 Fixed a bug in the Windows build where relative symbolic links were not
29 captured in reparse-point fixup mode.
31 Fixed a bug in the Windows build where file handles were left open to
32 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
34 Fixed a bug in the Windows build of wimlib-imagex where globbing
35 split-WIM parts could cause the program to crash.
37 Fixed a bug where the creation time of WIM images would be shown instead
38 of the last modification time.
40 With the Windows build it is now possible to restore a WIM containing
41 symbolic links as a non-Administrator; however you will receive warnings
42 about not being able to extract the symbolic links.
45 Capturing a WIM image should now be significantly faster in most cases
46 due to improved use of the operating system's cache and avoiding reading
47 files twice whenever possible.
49 The Windows build should now work on Windows XP.
51 The Windows build now supports capturing and restoring hidden,
52 compressed, sparse, and encrypted files.
54 The Windows build now supports capturing and applying WIM images from
55 filesystems other than NTFS (with some reduced functionality).
57 The Windows build now extracts short names correctly.
59 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
60 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
61 capture' and `wimlib-imagex apply'.
63 The performance of splitting and joining WIMs should be slightly
66 The LZX and XPRESS compression and decompression functions are now
67 exported from the library.
70 Improvements and bugfixes for the Windows build.
72 Added --strict-acls options.
74 Fixed the way that wimlib determines the order of images in the WIM.
77 Since wimlib can now be used on Windows, wimlib's implementation of
78 ImageX has been renamed to wimlib-imagex to avoid confusion with
79 Microsoft's implementation of ImageX, which would have the same file
80 name ("imagex.exe"). If you really don't like this you can pass the
81 --with-imagex-progname option to `configure' to choose a different name,
82 or even simply rename the binary yourself (but the former way will
83 configure the man pages to use the chosen name).
85 Various bugs fixed in the Windows build. Mainly to do with capturing
86 and restoring alternate data streams correctly in weird cases, and
87 requesting the correct privileges when opening files. Also added the
88 --noacls options to wimlib-imagex capture, append, and apply.
90 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
91 dynamically loaded, so this may make the library compatible with Windows
92 XP (however, there may still be other problems).
95 Added experimental support for native Windows builds. Binaries can be
96 downloaded from the SourceForge page.
98 --source-list option added to `imagex capture' and `imagex append'.
100 Better support for different character encodings.
103 Storing UNIX file owners, groups, and modes in WIM images is now
104 possible using `imagex capture' with the --unix-data flag.
106 Minor bug fixes and documentation fixes.
109 NTFS capture: Fixed capturing duplicate reparse points.
111 NTFS capture: Capture first unnamed stream if there are more than one
112 (print warning instead of error).
114 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
117 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
120 Update to work with ntfs-3g version 2013.1.13.
123 Fixed truncating file to shorter but non-zero length on read-write
126 Various code cleanups and minor documentation fixes.
129 LZX and XPRESS decompression have received some additional optimizations
130 and should now be even faster. (Although, they were already pretty
131 fast--- much faster than typical I/O speeds.)
133 Fixed a bug introduced in v1.2.1 that would cause a directory tree
134 containing hard links to be captured incorrectly in some cases.
137 By default, unmounting a read-write mounted WIM with 'imagex unmount
138 --commit' will now change the WIM in-place without needing to write the
139 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
142 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
143 for a response from the daemon servicing the mounted WIM. Instead,
144 every second 'imagex unmount' will check if the daemon is still alive,
145 and keep waiting if so, otherwise terminate with an error.
147 'imagex unmount --commit' on a read-write mounted WIM will now print
148 progress information regarding the writing of new or modified streams
149 the WIM, just like when capturing or appending a WIM.
151 A small change has been made to XPRESS compression and it should improve
152 the compression ratio slightly.
154 A change was made that may improve performance slightly when applying a
155 WIM image to a NTFS volume.
157 Microsoft has managed to introduce even more bugs into their software,
158 and now the WIMs for Windows 8 have incorrect (too low) reference counts
159 for some streams. This is unsafe because such streams can be removed
160 when they are in actuality still referenced in the WIM (perhaps by a
161 different image). wimlib will now work around this problem by fixing
162 the stream reference counts. This is only done when wimlib_delete_image() is
163 called ('imagex delete') or when wimlib_mount_image() is called with
164 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
165 requires reading the metadata for all images in the WIM, so this will
166 make these operations noticably slower on WIMs with multiple images.
168 Various other bugfixes.
171 Appending images to a WIM is now be done by default without re-building
172 the whole WIM. Use the --rebuild flag to get the old behavior (which
173 was to re-build the entire WIM when a new image is appended).
175 A new command `imagex optimize' is now available to manually re-build a
176 WIM that has wasted space due to repeated appends.
178 Progress information has been improved, and now arbitrary callback
179 functions can be used to show the progress of a WIM operation.
181 A possible bug with changing the bootable image of a WIM was fixed.
183 Some advisory locking is now done to prevent two processes from
184 modifying a WIM at the same time (but only in some cases). For example,
185 you cannot mount two images from a WIM read-write at the same time.
187 Some functions have been reorganized:
188 * wimlib_mount() renamed to wimlib_mount_image().
189 * wimlib_unmount() renamed to wimlib_unmount_image().
190 * wimlib_overwrite_xml_and_header() removed as
191 wimlib_overwrite() suffices now.
192 * wimlib_apply_image_to_ntfs_volume() removed as
193 wimlib_extract_image() suffices now.
194 * wimlib_add_image_from_ntfs_volume() removed as
195 * wimlib_add_image() suffices now.
197 Previously, the soname of libwim.so has been 0.0.0, despite many
198 interface changes. The soname is now updated to 1.0.0 and will now be
199 updated each release.
202 Resources will now be compressed using multiple threads by default.
203 (This applies to `imagex capture', `imagex append', and `imagex
206 Some performance improvements in mounted WIMs.
208 More progress information is shown when capturing a WIM.
211 Lots of minor fixes, code cleanups, and some documentation updates.
212 Nothing in particular is really noteworthy.
215 LZX and XPRESS compression improvements.
217 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
218 Link Bytes of the WIM.
221 Fixed bug when capturing NTFS file with multiple named data streams.
223 Internally, we are now using inode structures, even though these don't
224 appear literally in the WIM file. This simplifies some of the code
225 (mainly for WIM mounting) and likely fixed a few problems, although it
229 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
233 Enough changes to call it version 1.0.0!
235 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
236 to a NTFS volume, is now supported.
238 Hard links and symbolic links have much improved support. They are
239 supported for WIM capture, WIM application, and mounted WIMs (you can
240 even make them on read-write mounted WIMs).
242 Alternate data streams are now supported on mounted WIMs through an
243 xattr or a Windows-style stream interface. Also they are supported when
244 capturing a WIM from NTFS or applying a WIM to NTFS.
246 Split WIMs are better supported. You may now apply an image directly
247 from a split WIM, mount an image from a split WIM read-only, or export
248 an image from a split WIM.
250 Using a capture configuration file is now supported (but not fully yet).
252 SHA1 message digests are checked in more places, so we can make sure
253 applied and captured data is correct.
255 Man pages have been updated and consolidated.
258 Fixed segfault when unmounting read-only WIM.
261 Support for joining and splitting WIMs.
262 Also, security data is now preserved by default.
265 Can now build with older gcc and system headers, like on CentOS 5.
268 Fixed bug that made it impossible to overwrite files in read-write
272 Write byte-order mark before WIM XML data. (imagex.exe requires this to
