-- This is a complete rewrite of the NTFS driver that used to be in the kernel.
-  This new driver implements NTFS read support and is functionally equivalent
-  to the old ntfs driver.
+- This is a complete rewrite of the NTFS driver that used to be in the 2.4 and
+  earlier kernels.  This new driver implements NTFS read support and is
+  functionally equivalent to the old ntfs driver and it also implements limited
+  write support.  The biggest limitation at present is that files/directories
+  cannot be created or deleted.  See below for the list of write features that
+  are so far supported.  Another limitation is that writing to compressed files
+  is not implemented at all.  Also, neither read nor write access to encrypted
+  files is so far implemented.
 - The new driver has full support for sparse files on NTFS 3.x volumes which
   the old driver isn't happy with.
 - The new driver supports execution of binaries due to mmap() now being

 - The new driver supports fsync(2), fdatasync(2), and msync(2).
 - The new driver supports readv(2) and writev(2).
 - The new driver supports access time updates (including mtime and ctime).
-
+- The new driver supports truncate(2) and open(2) with O_TRUNC.  But at present
+  only very limited support for highly fragmented files, i.e. ones which have
+  their data attribute split across multiple extents, is included.  Another
+  limitation is that at present truncate(2) will never create sparse files,
+  since to mark a file sparse we need to modify the directory entry for the
+  file and we do not implement directory modifications yet.
+- The new driver supports write(2) which can both overwrite existing data and
+  extend the file size so that you can write beyond the existing data.  Also,
+  writing into sparse regions is supported and the holes are filled in with
+  clusters.  But at present only limited support for highly fragmented files,
+  i.e. ones which have their data attribute split across multiple extents, is
+  included.  Another limitation is that write(2) will never create sparse

@@ -439,6 +457,22 @@ ChangeLog
 
 Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
 
+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.
