+* Fri Apr 13 2012 Paul Howarth <paul@city-fan.org> 3.3.35-1
+- update to 3.3.35

+    yes in the rcfile to enable (e.g., for viewing interpolated analog
+    waveforms)
+  - added vcd_preserve_glitches support to FST as --optimize uses FST
+  - added vcd_preserve_glitches_real (for VCD/FST) rcfile variable that turns
+    off deglitching only for real signals
+  - fix for do_initial_zoom_fit when file requester used
+  - changed contact address for bug reports to bybell at rocketmail.com
+  - added fstWriterSetParallelMode()
