- Update to version 35:
* New features:
+ Libtool version info for shared ngspice
+ Version info in sharedspice.h.
+ Replace double braces {{...}} by {(...)} in netlist (PSLT
mode).
+ Add plotting of graphics in SVG format.
+ Setting variable 'nounits' allows suppressing the unit in a
graph.
+ Update of macOS configure script.
+ In sharedspice API, convert all boolean variables to type
integer for C++ compatibility.
+ Add geometry scaling to diode device model (level 3).
+ In PS mode exp function is limited to exp(14).
+ Speed enhancement for using SkyWater PDK under Linux.
+ Add option Cshunt which adds a capacitor to each circuit
voltage node.
+ Diode device model now has a self heating option.
+ Allow opening files with names containing ANSI special
characters.
+ Enable using parameters in .options lines.
+ For C and R devices enable value tokens like 4k7 or 1u2
in addition to 4.7k and 1.2u.
+ New XSPICE pswitch for internally replacing the vswitch.
+ Within a single run, allow multiple PS or SVG plots with
different names.
+ Don't replace a device model name by a parameter,
if both have the same names.
+ Analog delay code model 'delay'.
+ B source (ASRC) will acknowledge temp and dtemp instance
parameters.
+ In CIDER printing of either ASCII or binary is supported.
+ PSP models now support NMOS and PMOS, update to parameters
and examples.
+ E and G source TABLE function replaces by a B source pwl.
+ re-enable making the old help system for Linux/Cygwin
by --enable-help --enable-oldapps.
+ Enable the m parameter in E, G, B, R behavioral
source/devices.
* Bug fixes:
+ Many bugs fixed and code improvements (see ngspice bugs
539 and up, at SourceForge).
+ Memory leaks removed.

This *should* solve boo#1184825, but I haven't test or passed any additional build flags.
