 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.
+	- Improve handling of ntfs volumes with errors and strange boot sectors
+	  in particular.
+	- Fix various bugs.
 2.1.22:
 	- Improve handling of ntfs volumes with errors.
 	- Fix various bugs and race conditions.

 	- Add printk rate limiting for ntfs_warning() and ntfs_error() when
 	  compiled without debug.  This avoids a possible denial of service
 	  attack.  Thanks to Carl-Daniel Hailfinger from SuSE for pointing this
 	  out.
 	- Fix compilation warnings on ia64.  (Randy Dunlap)
-	- Use i_size_read() in fs/ntfs/attrib.c::ntfs_attr_set().
+	- Use i_size_{read,write}() instead of reading i_size by hand and cache
-	- Use i_size_read() in fs/ntfs/logfile.c::ntfs_{check,empty}_logfile().

-	- Use i_size_read() once and then use the cached value in
-	  fs/ntfs/lcnalloc.c::ntfs_cluster_alloc().
-	- Use i_size_read() in fs/ntfs/file.c::ntfs_file_open().
 	- Add size_lock to the ntfs_inode structure.  This is an rw spinlock
 	  and it locks against access to the inode sizes.  Note, ->size_lock
 	  is also accessed from irq context so you must use the _irqsave and
-	  _irqrestore lock and unlock functions, respectively.

-	- Use i_size_read() in fs/ntfs/compress.c at the start of the read and
+	  accesses to allocated_size, initialized_size, and compressed_size.
-	  use the cached value afterwards.  Cache the initialized_size in the
-	  same way and protect access to the two sizes using the size_lock.
-	- Use i_size_read() in fs/ntfs/dir.c once and then use the cached
-	  value afterwards.
-	- Use i_size_read() in fs/ntfs/super.c once and then use the cached
-	  value afterwards.  Cache the initialized_size in the same way and
-	  protect access to the two sizes using the size_lock.
 	- Minor optimization to fs/ntfs/super.c::ntfs_statfs() and its helpers.
-	- Use i_size_read() in fs/ntfs/inode.c once and then use the cached
-	  value afterwards when reading the size of the bitmap inode.
-	- Use i_size_{read,write}() in fs/ntfs/{aops.c,mft.c} and protect
-	  access to the i_size and other size fields using the size_lock.
 	- Implement extension of resident files in the regular file write code
 	  paths (fs/ntfs/aops.c::ntfs_{prepare,commit}_write()).  At present
 	  this only works until the data attribute becomes too big for the mft
