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