Major update on the testing features:

  • Support for template-based program generation
  • Support for template macros
  • Support for multi-mode test cases (kernel mode, user mode, VM mode, and transitions between them)
  • Support for actors: Isolated parts of test case that have their own code and data, and that can interact with each other
  • Added architectural fuzzing mode for detecting mismatches between the model and the executor
  • Added TSC (time stamp counter) measurement mode
  • Rewritten analyzer to support multiple analysis modes. Changed default analyzer to a statistics (chi2)-based one
  • Added an option to track instruction coverage
  • Added value speculation contracts
  • Added a non-interference model for testing information flows between actors

Wider support for x86-64 ISA:

  • Support for 128-bit SIMD (SSE 1-4)
  • Correct handling of IDIV
  • Intel MPX exceptions

Stability features:

  • Synchronized seeds for both program and input generators
  • Multi-pass testing of detected violations to gradually remove various known types of False Positives
  • Many improvements to the logging infrastructure
  • Pass-based re-implementation of minimizer
  • Graceful propagation of errors from executor up to the user interface
  • Implemented full fault sandbox for catching bugs in executor without causing crashes
  • State machine-based monitoring of incomplete measurements in executor

And also a bit more documentation on cli, config, and minimization.
