   The latest version released is:
 
-  * ngspice-28 (released on ../../2018)
+  * ngspice-29 (released on ../../2018)
 
 
  2.2.  What are the latest features in the current release?
 
 - New features:
-    + VDMOS power MOS model added
-    + if 'set ngbehavior=ps' is given in .spiceinit, device libraries loaded
-      via .include may have PSPICE syntax 
-    + --enable-oldapps configure flag to compile the old, seldom used apps
-      ngmakeidx, ngmultidec, ngproc2mod, ngsconvert
-    + add command mc_source to internally re-load the circuit
-    + add command alterparam to alter the value of a parameter xxx given in .param xxx=value    
-    + add the fiunction i(xyz) to measure the current in node 1 of device xyz, to be
-      used in .params and behavioral models.
-    + new label 'noretraceplot' for the 'plot' command, if graphs in a plot show unwanted
-      retracing lines.
-    + The hyphen '-' is a valid character in model, device and subcircuit names
-    + add noise for behavioral resistor
-    + add a new vector type "temperature"
-    + support instance parameter defaults on .model lines
-    + New functions for XSPICE event node data export from shared ngspice: 
-      ngGet_Evt_NodeInfo(char*) and ngSpice_AllEvtNodes(void)
-    + 'edisplay' command now showing node name, node type and number of events per node 
-    + add flag 'none' to the 'save' commandfor shared ngspice. 
-      Output data will not be stored, but are available via callback function ng_data.
-    + add a function cm_get_circuit to allow accessing the circuit structure ckt 
-      from within an XSPICE code model.
-    + add variable 'sim_status' to indicate if a simulation has been aborted
-    + add pkg-config file
+    + configure flag --with-fftw3 If set to 'no', internal fast fourier is used
+      instead of fftw
+    + command setseed to set the seed value for the random number generator
+    + option seed=[val|random]
+    + variable inputdir to remeber and retrieve the last input file directory
+    + example directory 'digital' with analog, behavioral and digital example input files
+    + new XSPICE filesource, d_source, and state-machine examples
+    + +, - maybe part of instance name
+    + Quasi-saturation VDMOS example
+    + add environmental variable SOURCE_DATE_EPOCH to allow reproducible executables
+    + new parameters to command setplot: setplot next, setplot previous
+    + updates to commands cd, rusage, print
+    + update to bipolar and diode temperature equations
 
 - Bug fixes:
-    + many, many ... as always
+    + several bug fixes
+    + lots of memory leaks removed, especially when XSPICE circuits are called several
+      times in a loop.
