+============
+- New features:
+    + Add multiplier flag 'm' to behavioral capacitor and inductor
+    + Re-enable dc sweep after transient sim
+    + When plotting the phase, standard now is "Radiant".
+    + Add Lundin's geometry correction to the inductance formula
+    + New variable keep#branch to write the current to raw file
+      in the old fashion     	1	v1#branch	current
+    + Translate PSPICE U instances into equivaalent XSPICE code models.
+    + New configure flag --enable-shortcheck to enable a shortened make check
+     (only BSIM3 and BSIM4)
+    + B source will accept parameters in statistical functions like agauss
+    + WinGUI: Add a button 'Stop' to stop a simulation in intercative
+      or control mode.
+    + Update to the .probe p command (power measurement)
+    + Update to XSPICE aswitch and pswitch
+    + Make FROM/TO work in TRIG/TARG and WHEN variants of .meas/meas command.
+    + Limits to exp function, allow 0 for log (returning -1e99)
+      when starting iteration
+    + Insert XSPICE bridging devices automatically when an analogue node
+      has the same name as an XSPICE event node.
+    + New options savecurrents_bsim3, savecurrents_bsim4, and savecurrents_mos1
+    + pwlts: a pwl v/i source with time input, smoothing and limiting functions
+    + New functions to the Code Model Library: cm_get_node_name()
+      and cm_probe_node()
+    + XSPICE: Add bidirectional digital/analog bridge.
+    + Search for .spiceinit firstly in a user defined directory named in env
+      SPICE_USERINIT_DIR, then in the current directory, then in HOME, then
+      in USERPROFILE.
+    + If compatmode is lt, change the pow(x,y) and x**y functions:
+      If x < 0, output only if y is integer number, otherwise output 0
+    + Add a limit of 0.999 to bipolar parameters mje, mjc, and mjs.
+
+- Bug fixes:
+    + many bugs fixed and code improvements (see bugs 583 and up)
+    + making error messages more verbose
+    + memory leaks removed
+
