-    - detangled receiver streaming from data call back in client

-    - (eiger) software trigger made to work along with blocking acquire
-    - bug fix for locks in blocking acquire
-    - parameter file allows for modular commands

 2. Resolved Issues
 ==================          
 
-    Client
-    ------
+    Detector Server (Eiger)
+    -----------------------
     
-    1.  Registering data call back (registerDataCallback) used to enable data streaming 
-        via zmq in both receiver and client. Sending NULL unregistered call back, 
-        but did not disable streaming. 
-        Now, registering/unregistering this call back will only enable data streaming
-        in client. Data streaming in receiver will have to be explicitly enabled.
+    1.  Vcal dac set to 0 at on-board detector server start up to
+        reduce noise.
 
-    2.  (Eiger)
-        Software trigger triggered via the stop server and hence, can be triggered
-        also during blocking acquire.
+    2.  Deactivate will deactivate a module even if FEB does not work.
 
-    3.  If stop acquisition command was given immediately after starting a blocking acquire,
-        it might have hanged the process. This bug is fixed now.
+    3.  Trimbits values checked for values 0 - 63.
 
-    4.  Parameter file now allows modular commands (using ':'). They are not ignored anymore.
-    
+    Receiver
+    --------
+
+    1.  zmq socket send memory not overlapping
+    2. fifo size not be large (and memory allocated print to mb)
+
+    - subexptime also sets subperiod in master fle
