@ -5,6 +5,7 @@ Language Features:
Compiler Features:
* Command Line Interface: Report error if file could not be read in ``--standard-json`` mode.
* Command Line interface: Report proper error for each output file which could not be written. Previously an exception was thrown, and execution aborted, on the first error.
* SMTChecker: Add division by zero checks in the CHC engine.
* SMTChecker: Support ``selector`` for expressions with value known at compile-time.
* Command Line Interface: New option ``--model-checker-timeout`` sets a timeout in milliseconds for each individual query performed by the SMTChecker.
