    * 1998-2003 Development continued at Caltech, including embedding CAST-like syntax within the Modula-3 language. This version was used to design the Lutonium processor.
    * 2004 A language that provided the same functionality as CAST but with syntax for new features (not implemented) was developed at Cornell by Rajit Manohar, based on lessons from using CAST for chip design. This was called ACT (version 0; 0 because the new features were not supported yet)

    * 2005-2010 An open-source (GPLed) implementation of an ACT v0 variant (called "HACKT") was developed by David Fang (student in Rajit Manohar's group) as part of his Ph.D. dissertation.
    * 2005-2014: ACT was used to implement a large number of asynchronous chips, including microprocessors, FPGAs, a GPS baseband engine, digital circuits in continuous-time signal processing hardware, neuromorphic hardware, etc.
