Overflow 0.6.1 released

We're pleased to announce the release of Overflow 0.6.1. This release has mostly focused on bug fixing and improving the core library. This release is compatible at the XML level with 0.6.0 but not at the source/binary level. Those who have
nodes coded in C++ should 's/specificInitialize/initialize/' their source file.

Changes :

  • Method renamed: specificInitialize() has been renamed to initialize(). This affects those who write their own nodes.
  • Cancelling a program with the "stop" button has now less chances fo crashing Overflow.
  • Node CAllPole was renamed to IIR, making it more clear what the node is doing.
  • Various GUI improvements
  • Many bug fixes (possibly new ones)
  • Real-Time Clock (/dev/rtc) support for timing/waiting
  • Added user-defined struct-like types throught the use of the MakeComposite and GetComposite nodes
  • Various GUI improvements.... read more
