1 Only the most important changes more recent than version 0.6 are noted here.
4 LZX and XPRESS decompression have received some additional optimizations
5 and should now be even faster. (Although, they were already pretty
6 fast--- much faster than typical I/O speeds.)
9 By default, unmounting a read-write mounted WIM with 'imagex unmount
10 --commit' will now change the WIM in-place without needing to write the
11 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
14 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
15 for a response from the daemon servicing the mounted WIM. Instead,
16 every second 'imagex unmount' will check if the daemon is still alive,
17 and keep waiting if so, otherwise terminate with an error.
19 'imagex unmount --commit' on a read-write mounted WIM will now print
20 progress information regarding the writing of new or modified streams
21 the WIM, just like when capturing or appending a WIM.
23 A small change has been made to XPRESS compression and it should improve
24 the compression ratio slightly.
26 A change was made that may improve performance slightly when applying a
27 WIM image to a NTFS volume.
29 Microsoft has managed to introduce even more bugs into their software,
30 and now the WIMs for Windows 8 have incorrect (too low) reference counts
31 for some streams. This is unsafe because such streams can be removed
32 when they are in actuality still referenced in the WIM (perhaps by a
33 different image). wimlib will now work around this problem by fixing
34 the stream reference counts. This is only done when wimlib_delete_image() is
35 called ('imagex delete') or when wimlib_mount_image() is called with
36 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
37 requires reading the metadata for all images in the WIM, so this will
38 make these operations noticably slower on WIMs with multiple images.
40 Various other bugfixes.
43 Appending images to a WIM is now be done by default without re-building
44 the whole WIM. Use the --rebuild flag to get the old behavior (which
45 was to re-build the entire WIM when a new image is appended).
47 A new command `imagex optimize' is now available to manually re-build a
48 WIM that has wasted space due to repeated appends.
50 Progress information has been improved, and now arbitrary callback
51 functions can be used to show the progress of a WIM operation.
53 A possible bug with changing the bootable image of a WIM was fixed.
55 Some advisory locking is now done to prevent two processes from
56 modifying a WIM at the same time (but only in some cases). For example,
57 you cannot mount two images from a WIM read-write at the same time.
59 Some functions have been reorganized:
60 * wimlib_mount() renamed to wimlib_mount_image().
61 * wimlib_unmount() renamed to wimlib_unmount_image().
62 * wimlib_overwrite_xml_and_header() removed as
63 wimlib_overwrite() suffices now.
64 * wimlib_apply_image_to_ntfs_volume() removed as
65 wimlib_extract_image() suffices now.
66 * wimlib_add_image_from_ntfs_volume() removed as
67 * wimlib_add_image() suffices now.
69 Previously, the soname of libwim.so has been 0.0.0, despite many
70 interface changes. The soname is now updated to 1.0.0 and will now be
74 Resources will now be compressed using multiple threads by default.
75 (This applies to `imagex capture', `imagex append', and `imagex
78 Some performance improvements in mounted WIMs.
80 More progress information is shown when capturing a WIM.
83 Lots of minor fixes, code cleanups, and some documentation updates.
84 Nothing in particular is really noteworthy.
87 LZX and XPRESS compression improvements.
89 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
90 Link Bytes of the WIM.
93 Fixed bug when capturing NTFS file with multiple named data streams.
95 Internally, we are now using inode structures, even though these don't
96 appear literally in the WIM file. This simplifies some of the code
97 (mainly for WIM mounting) and likely fixed a few problems, although it
101 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
105 Enough changes to call it version 1.0.0!
107 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
108 to a NTFS volume, is now supported.
110 Hard links and symbolic links have much improved support. They are
111 supported for WIM capture, WIM application, and mounted WIMs (you can
112 even make them on read-write mounted WIMs).
114 Alternate data streams are now supported on mounted WIMs through an
115 xattr or a Windows-style stream interface. Also they are supported when
116 capturing a WIM from NTFS or applying a WIM to NTFS.
118 Split WIMs are better supported. You may now apply an image directly
119 from a split WIM, mount an image from a split WIM read-only, or export
120 an image from a split WIM.
122 Using a capture configuration file is now supported (but not fully yet).
124 SHA1 message digests are checked in more places, so we can make sure
125 applied and captured data is correct.
127 Man pages have been updated and consolidated.
130 Fixed segfault when unmounting read-only WIM.
133 Support for joining and splitting WIMs.
134 Also, security data is now preserved by default.
137 Can now build with older gcc and system headers, like on CentOS 5.
140 Fixed bug that made it impossible to overwrite files in read-write
144 Write byte-order mark before WIM XML data. (imagex.exe requires this to
