Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
+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).
2.1.22:
- Improve handling of ntfs volumes with errors.
- Fix various bugs and race conditions.
