Qucs-S 1.0.0

About this release

I am glad to present Qucs-S v1.0.0! Switching to v1.0.0 version number indicates that Qucs-S is a mature software ready for professional usage. Thanks Tom Hajjar @tomhajjar and Sergey Krasilnikov @zergud for testing and contribution!

New features

• Added basic support for logic gates simulation (Ngspice >= 38) required #97
• Added possibility to set engineering notation (like 1k, 1M, etc.) for numbers on diagrams #92
• Added symbol preview and search feature for component library in main windows #135
• Backported qucs-attenuator, qucs-transcalc and qucs-powercombining from Qucs-0.0.20 #142
• Added possibility to set dB units for Y-axis on digrams from the diagram properties dialog #92
• Backported advanced features for projects tree from Qucs-0.0.20 #95
• Show warning if schematic file name changed, but dataset/display file name are not updated #111
• Revised examples tree (by Tom Hajjar @tomhajjar); legacy Ngspice-incompatible examples
  moved to examples/qucsator subdirectory

Component library

• Qucs-lib tool has been removed from the application; all its features are
  availbale now from the main window left panel #139
• Fixed Tubes.lib and LEDs.lib libraries (by @tomhajjar)

General improvements

• Fixed numerous bug reports. Thanks @tomhajjar and @zergud for testing and providing patches.

Windows

• Added 32-bit Windows portable package

Known issues

• Parameter sweep doesn't work when using the Fourier simulation with XYCE backend #73
• Netlister may produce duplicate .SUBCKT entry when using the same component from user and system library #82
• Auto-scaling on diagram may fail on some conditions for Windows 64-bit platform #133 Other platforms are not affected
• The 1-point AC simulation produce a set of 1x1 plot if ParameterSweep instead of smooth curve is attached #156
