[Pkg-electronics-devel] Bug#1108620: ngspice: Prospective upgrade of blt to 3.0 affects ngspice

[Holger Vogt]

Carsten,

the next ngspice release (45) is planned for end of July.

Up to now I did not consider any changes to the tclspice port.

I will have a look at the BLT 3 sources.

What about putting these changes into ngspice-46 (end of 2025)?

Best regards

Holger
