    Release Notes: Several bugs have been fixed, improving stability and reliability. A compatibility mode for dealing with other simulators was added. BSIM 4 was updated to release 4.6.5. BSIMSOI was updated to version 4.3.1. Transmission lines from kspice were updated and corrected. B sources were improved with a PWL function, the addition of "HERTZ", "time" and "temper" variables, and the addition of a Ternary function. PWL sources were improved with a repeat parameter (r=value) and a delay parameter (td=value).

      Release Notes: The Tclspice simulator library has been merged with ngspice. New options have been introduced: brief, listing, autostop, and scale. Support for .lib files has been introduced. .measure statements: avg, integ, rms, max, min, delay, and param. .global statement support. .func macros for inlining functions into netlists. The numparam library has been improved to support fully parametrized netlists. BSIM model binning. New multi-input gate VCVS using XSPICE extensions.

          Release Notes: Most of the bugs have been fixed, so ngspice is more stable, especially the xspice extension, subcircuit handling, and numparam library. The syntax has been expanded, allowing for end-of-line comments. A ".global" card has beed added to define global nodes. It is possible to define TC for resistors on the instance line. The editline library can be used instead of readline. ngspice now works (with xspice) on Windows using MINGW/MSYS.

              Release Notes: The Xspice simulator and the Cider simulator were added. The Numparam library was added, allowing for parameter substitution at the netlist level. The models were improved: the Diode model includes periphery and high level of injection effects. BJT and BJT2 were enhanced. BSIM3 now includes ACM. The BSIM4 implementation was corrected. New models include VBIC (3 Terminals, no excess phase and thermal network) and HiSIM. Frontend leaks were closed. Many new example files were added. The Xgraph plotting program is included.

                  Release Notes: There is now no more segfault at start. Other minor fixes have been made in the frontend.
