Qucs-S 24.3.0

New features

• SpiceLibComp redesign. This device is renamed to Spice Library Device and provides an easy way
  to add SPICE model to schematic and assign symbol to it. See #679
• Added possibity to import SPICE model for Diode, BJT, MOSFET, and JFET unified devices (blue) #795
• Implemeted symbol files (*.sym) editing mode. These files are needed to attach symbol to SPICE devices #700
• Redesign of schematic rendering engine. Improve rendering quality on HiDPI displays #723 (by @wawuwo )
• Improved Qucsconv GUI to reflect new converter features #826
• Improved libraries portability, relative path support for libraries, show libraries from project directory #567
• Added a global setting for Ngspice compatibility mode (LTspice, HSPICE, etc.) #851
• Add global Ngspice compatibility mode (LTspice/HSPICE/S3) setting #851
• Updated attenuator and filter synthesis tools (by @andresmmera )
• QucsatorRF updated to version 1.0.1

Deprecated features

• The *.qucs binary archives are not supported anymore. Use system archivers to pack the projects instead #811
• The SweepModel property of Parameter Sweep simulaiton has been deprecated. It is not needed anymore after Ngspice
  has added variable sweep feature. Use variable sweep instead #839
• Toolbars and status bar made always visible #852
• Icons theme settings removed from settings dialog. These settings have no effect since v2.1.0
  when unified and auto-generated icons were introduced.

Packaging

• Linux DEB and RPM packages switched to Qt6
• Windows package switched to Qt6
• Introduced continous release of Linux, Windows, and Mac packages #719
• Added MacOS package build #797 and homebrew support #804 (thanks @dsm )
• Windows installer includes asco.exe optimizer

General improvements

• The TEMP and TEMPER variables are recognized by parameter sweep to apply temperature sweep #816
• Fixed ASCO optimization with QucsatorRF #830
• Enabled variables as parameters for unified nonlinear devices and pulsed source #838 and #808
• Fixed issues with XYCE simulation #701
• Improved attenuator synthesis tool #722
• Improved filter synthesis tool #715 #673
• Redesign File->Open examples menu. Show open dialog instead of file manager #672
• Qucs-S now follows XDG standard for cached data location #145
• Apply .OPTION INTERP when simulating transient with parameter sweep; prevent broken par. sweep data #766
• Implemented relative paths support for library devices #567

Component library

• Added PWM controllers (TL494, UC384x, etc.) library #846
• Added Germanium diodes library #846
• Added Mixer IC library containing SA612 model #846
• Added Diodes extended library containing different USSR diodes models
• Added new Varactor library #759
• Added new PIN diode library #764

Localization

• Russian translation update
