Compiler Features:
* SMTChecker: Properties that are proved safe are now reported explicitly at the end of the analysis. By default, only the number of safe properties is shown. The CLI option ``--model-checker-show-proved-safe`` and the JSON option ``settings.modelChecker.showProvedSafe`` can be enabled to show the full list of safe properties.

There is no precise heuristic on how and when to split verification targets,
but it can be useful especially when dealing with large contracts.
Proved Targets
==============
If there are any proved targets, the SMTChecker issues one warning per engine stating
how many targets were proved. If the user wishes to see all the specific
proved targets, the CLI option ``--model-checker-show-proved`` and
the JSON option ``settings.modelChecker.showProved = true`` can be used.
Unproved Targets
================
