CPAchecker Release 4.2 (unix)

Published November 24, 2025 | Version 4.2 (unix)

Software Open

Changes from CPAchecker 4.1 to CPAchecker 4.2

Java 21 or later is required now.
When parsing C code, CPAchecker now immediately attempts to parse the code with an external pre-processor to resolve system headers in case the usual parsing failed. To use the previous behavior, which did not use an external pre-processor, set the option cfa.usePreprocessor to false.
There is now support for analyzing SV-LIB programs with predicate analysis in CPAchecker.
CPAchecker can now validate violation witnesses for termination in YAML format version 2.1. Moreover, there is a new validation technique that can also be used for witnesses in version 1.0.
There is an export of termination witnesses in YAML format version 2.1 that constructs transition invariants from ranking functions.
CPAchecker can now validate correctness witnesses for termination in YAML format 2.1.
CPAchecker now supports the sequentialization of concurrent programs which it can export and/or verify internally using its sequential analyses.
