+2.1.27:
+ - Implement page migration support so the kernel can move memory used
+ by NTFS files and directories around for management purposes.
+ - Add support for writing to sparse files created with Windows XP SP2.
+ - Many minor improvements and bug fixes.
+2.1.26:
+ - Implement support for sector sizes above 512 bytes (up to the maximum
+ supported by NTFS which is 4096 bytes).
+ - Enhance support for NTFS volumes which were supported by Windows but
+ not by Linux due to invalid attribute list attribute flags.
+ - A few minor updates and bug fixes.
+2.1.25:
+ - Write support is now extended with write(2) being able to both
+ overwrite existing file data and to extend files. Also, if a write
+ to a sparse region occurs, write(2) will fill in the hole. Note,
+ mmap(2) based writes still do not support writing into holes or
+ writing beyond the initialized size.
+ - Write support has a new feature and that is that truncate(2) and
+ open(2) with O_TRUNC are now implemented thus files can be both made
+ smaller and larger.
+ - Note: Both write(2) and truncate(2)/open(2) with O_TRUNC still have
+ limitations in that they
+ - only provide limited support for highly fragmented files.
+ - only work on regular, i.e. uncompressed and unencrypted files.
+ - never create sparse files although this will change once directory
+ operations are implemented.
+ - Lots of bug fixes and enhancements across the board.
+2.1.24:
+ - Support journals ($LogFile) which have been modified by chkdsk. This
+ means users can boot into Windows after we marked the volume dirty.
+ The Windows boot will run chkdsk and then reboot. The user can then
+ immediately boot into Linux rather than having to do a full Windows
+ boot first before rebooting into Linux and we will recognize such a
+ journal and empty it as it is clean by definition.
+ - Support journals ($LogFile) with only one restart page as well as
+ journals with two different restart pages. We sanity check both and
+ either use the only sane one or the more recent one of the two in the
+ case that both are valid.
+ - Lots of bug fixes and enhancements across the board.
+2.1.23:
+ - Stamp the user space journal, aka transaction log, aka $UsnJrnl, if
+ it is present and active thus telling Windows and applications using
+ the transaction log that changes can have happened on the volume
+ which are not recorded in $UsnJrnl.
+ - Detect the case when Windows has been hibernated (suspended to disk)
+ and if this is the case do not allow (re)mounting read-write to
+ prevent data corruption when you boot back into the suspended
+ Windows session.
+ - Implement extension of resident files using the normal file write
+ code paths, i.e. most very small files can be extended to be a little
+ bit bigger but not by much.
+ - Add new mount option "disable_sparse". (See list of mount options
+ above for details.)
+ - Improve handling of ntfs volumes with errors and strange boot sectors
+ in particular.
+ - Fix various bugs including a nasty deadlock that appeared in recent
+ kernels (around 2.6.11-2.6.12 timeframe).
