+2. New Features
+===============
+
+    Receiver
+    --------
+    1.  Memory in receiver is now byte aligned and write to every page
+        at memory allocation to ensure complete memory allocated right
+        from start. Removed file buffering when writing to file. Replaced
+        pausing on keepRunning variable with semaphore to reduce cpu
+        load.
+
+    Client
+    ------
+    1.  Added setflippeddatax to users class.

 ==================          
 
     Detector Server (Eiger)
     -----------------------
-    
     1.  Vcal dac set to 0 at on-board detector server start up to
         reduce noise.
 
-    2.  Deactivate will deactivate a module even if FEB does not work.
+    2.  Setting activate to 0 sent to both control and stop server.
+        So, deactivate a module can be done even if FEB communication fails.
+        Restarting the server will activate the module again.
 
-    3.  Trimbits values checked for values 0 - 63.
+    3.  Setting all trimbits values checked for values 0 - 63.
 
     Receiver
     --------
+    1.  Earlier, setting rx_fifodepth to a high value would set to 
+        a lower value, printing this low value to console, 
+        but not giving an error. Memory allocated can now take in 64 bits.
+    
+    2.  Modifying subexptime now also updates subperiod in master file.
+        Also, the print for subperiod name to console is corrected.
 
-    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
-
-3. Known Issues
-===============
+    Package
+    -------
+    1.  Many warnings have been fixed, including those with overlapping 
+        memory copies for source and destination.
