 Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
 
+2.0.13:
+	- Internal changes towards using iget5_locked() in preparation for
+	  fake inodes and small cleanups to ntfs_volume structure.
+2.0.12:
+	- Internal cleanups in address space operations made possible by the
+	  changes introduced in the previous release.
+2.0.11:
+	- Internal updates and cleanups introducing the first step towards
+	  fake inode based attribute i/o.
 2.0.10:
 	- Microsoft says that the maximum number of inodes is 2^32 - 1. Update
 	  the driver accordingly to only use 32-bits to store inode numbers on

 	- Consider if ntfs_file_read_compressed_block() shouldn't be coping
 	  with initialized_size < data_size. I don't think it can happen but
 	  it requires more careful consideration.
-	- CLEANUP: Modularise and reuse code in aops.c. At the moment we have
-	  several copies of almost identicall functions and the functions are
-	  quite big. Modularising them a bit, e.g. a-la get_block(), will make

+	- CLEANUP: At the moment we have two copies of almost identical

+	  based attribute i/o is further developed.
+	- CLEANUP: Modularising code in aops.c a bit, e.g. a-la get_block(),
+	  will be cleaner and make code reuse easier.
+	- Modify ntfs_read_locked_inode() to return an error code and update
+	  callers, i.e. ntfs_iget(), to pass that error code up instead of just
+	  using -EIO.
+	- Enable NFS exporting of NTFS.
+	- Use fake inodes for address space i/o.
+
+2.0.13 - Use iget5_locked() in preparation for fake inodes and small cleanups.
+
+	- Remove nr_mft_bits and the now superfluous union with nr_mft_records
+	  from ntfs_volume structure.
+	- Remove nr_lcn_bits and the now superfluous union with nr_clusters
+	  from ntfs_volume structure.
+	- Use iget5_locked() and friends instead of conventional iget(). Wrap
+	  the call in fs/ntfs/inode.c::ntfs_iget() and update callers of iget()
+	  to use ntfs_iget(). Leave only one iget() call at mount time so we
+	  don't need an ntfs_iget_mount().
+	- Change fs/ntfs/inode.c::ntfs_new_extent_inode() to take mft_no as an
+	  additional argument.
+
+2.0.12 - Initial cleanup of address space operations following 2.0.11 changes.
+
+	- Merge fs/ntfs/aops.c::end_buffer_read_mst_async() and
+	  fs/ntfs/aops.c::end_buffer_read_file_async() into one function
+	  fs/ntfs/aops.c::end_buffer_read_attr_async() using NInoMstProtected()
+	  to determine whether to apply mst fixups or not.
+	- Above change allows merging fs/ntfs/aops.c::ntfs_file_read_block()
+	  and fs/ntfs/aops.c::ntfs_mst_readpage() into one function
+	  fs/ntfs/aops.c::ntfs_attr_read_block(). Also, create a tiny wrapper
+	  fs/ntfs/aops.c::ntfs_mst_readpage() to transform the parameters from
+	  the VFS readpage function prototype to the ntfs_attr_read_block()
+	  function prototype.
+
+2.0.11 - Initial preparations for fake inode based attribute i/o.
+
+	- Move definition of ntfs_inode_state_bits to fs/ntfs/inode.h and
+	  do some macro magic (adapted from include/linux/buffer_head.h) to
+	  expand all the helper functions NInoFoo(), NInoSetFoo(), and
+	  NInoClearFoo().
+	- Add new flag to ntfs_inode_state_bits: NI_Sparse.
+	- Add new fields to ntfs_inode structure to allow use of fake inodes
+	  for attribute i/o: type, name, name_len. Also add new state bits:
+	  NI_Attr, which, if set, indicates the inode is a fake inode, and
+	  NI_MstProtected, which, if set, indicates the attribute uses multi
+	  sector transfer protection, i.e. fixups need to be applied after
+	  reads and before/after writes.
+	- Rename fs/ntfs/inode.c::ntfs_{new,clear,destroy}_inode() to
+	  ntfs_{new,clear,destroy}_extent_inode() and update callers.
+	- Use ntfs_clear_extent_inode() in fs/ntfs/inode.c::__ntfs_clear_inode()
+	  instead of ntfs_destroy_extent_inode().
+	- Cleanup memory deallocations in {__,}ntfs_clear_{,big_}inode().
+	- Make all operations on ntfs inode state bits use the NIno* functions.
+	- Set up the new ntfs inode fields and state bits in
+	  fs/ntfs/inode.c::ntfs_read_inode() and add appropriate cleanup of
+	  allocated memory to __ntfs_clear_inode().
