• Instrumentation optimizations that provide a significant runtime speedup
• Metadata and ground-truth control flow information are now stored to the database
• Adds the ability to track multiple input files as well as writes to output files
• Adds an instrumentation-time option to omit control-flow tracking data, providing a significant speedup
• Adds a new feature to map input byte offsets to output byte offsets, e.g., to detect "cavities" in the input file (i.e., regions of the input file that neither affect control flow nor influence a byte written to an output file).
