 Summary of changes between versions 1.0.0 and 1.0.1
 ---------------------------------------------------
 
- - Update for 2.6.26
+ - Support for descriptor sense format added
 
- - Minor fixes and cleanups
+ - Makefiles made more packager friendly (Ruben Laban)
+
+ - Support for variable lenght CDB added
+
+ - Support for Async. Event Notifications added
+ 
+ - Implemented "plug-and-play" notifications about new devices in security
+   groups, deleted devices from security groups and changed size of a
+   device. They can be delivered either through AENs (if supported), or
+   Unit Attentions.
+  
+ - New command "resync_size" added to scst_vdisk proc interface to tell
+   scst_vdisk to reread size of the corresponding device after it was
+   changed
+
+ - Added pattern matching for initiator names in SCST access control
+   (Gennadiy Nerubayev)
+
+ - Now only sent for execution commands are counted to wait for in TM
+   commands, which made processing of TM commands faster
+
+ - Now devices blocked only in reset TM commands. ABORTs, etc. now done
+   without devices blocking.
+
+ - scst_unregister_session_ex() removed, since there are no users of it
+
+ -  New functions added to scst_user interface:
+ 
+    * SCST_USER_UNREGISTER_DEVICE - to unregister device, flush mem reuse
+     (SGV) cache and send UCMD_STATE_ON_CACHE_FREEING notifications for all
+     freed buffers to the user space handler. Simple device close doesn't
+     allow that, so all the cached buffers might look as "leaked" from the
+     user space handler POV.
+  
+    * SCST_USER_FLUSH_CACHE - to flush mem reuse (SGV) cache and send
+      UCMD_STATE_ON_CACHE_FREEING notifications for all freed buffers to
+      the user space handler
+
+    * SCST_USER_DEVICE_CAPACITY_CHANGED - to notify SCST core that the
+      corresponding device has changed its capacity
+
+ - Clustering of scst_user pages added
+
+ - Added autogenerated SCSI SN in vdisk handler
+
+ - Fixed race in scst_user, which could have lead to usage of already freed
+   command. A misbehaving user space handler could have made ucmd to get
+   dead immediately after the lock is released and that is caught
+   now.
+
+ - Support for CentOS 5.2 added (Bart Van Assche)
+
+ - In scst_vdisk new module parameter num_threads added to specify a
+   number of threads for each vdisk/vcdrom. Default is 5.
+
+ - Access control docs updated
+
+ - Set memory limits according to LOWMEM, not TOTALMEM
+
+ - Major performance increase working with disk based storage
+
+ - Now task_mgmt_fn() callback called for TARGET RESET and NEXUS LOSS
+   functions only once for tgt_dev, which belongs to the session, from
+   which the corresponding request came
+
+ - SGV cache related parameters moved from scst.h to scst_sgv.h
+
+ - Log level mgmt_minor for messages like "Warning: expected transfer
+   length X for opcode Y" changed to be disabled by default
+
+ - Added possibility to coexist if both target driver and dev handler
+   need custom memory allocation. Direct consequences: (1) scst_local
+   can work with scst_user's devices and (2) scst_user now compatible
+   with iscsi-scst if put_page_callback patch not applied.
+
+ - Depecated scst_cmd_get_tgt_resp_flags() removed
+
+ - SWP and TAS parameters made changable in vdisk handler
+
+ - External interface changed to fix usage of in_atomic(). Now target
+   drivers and dev handlers need to explicitly supply preferred execution
+   context in scst_cmd_done() and scst_tgt_cmd_done()
+
+ - Handling of internal REQUEST SENSE fixed.
+
+ - Fixed SAM violation (HiSup bit must be set in INQUIRY response)
+
+ - Fixed handling of VERIFY commands that comes with BYTCHK unset
+
+ - Handling of double reset UAs made more reliable
+
+ - A lot of kernel style, checkpatch and sparse fixes (Bart Van Assche)
+
+ - In-kernel build integration (Bart Van Assche)
+
+ - Update for kernels up to 2.6.29
+
+ - A lot of fixes and cleanups (many people)
