| Cppcheck 2.19.0 Dec 22, 2025 |
Major bug fixes & crashes: Crash in CheckClass::checkConst() fuzzing crash (assert) in Token::update_property_info() Crash in checkConstVariable() Crash in valueFlowLifetimeClassConstructor() GUI: scratch pad crash Assert failure in getParentValueTypes() Crash in simplecpp::Macro::expand() crash in Tokenizer::simplifyCPPAttribute() New checks: Detect zero initialization of unions in which its largest member is not declared as the first one. Depending on the compiler, there's no guarantee that the complete union will be zero initialized in such scenarios leading to potential access of uninitialized memory. Added warning when main() throws an exception C/C++ support: Fixed syntax error for C++23 lambda without parameter clause Added support for typeof and __typeof operators GUI: Fix bug: checks multiple configurations even though user provides defines Changed interface: some preprocessorErrorDirective and syntaxError errors got more specific error IDs. Removed deprecated platforms unix32-unsigned and unix64-unsigned Improve progress value Added float bits support in platform configuration Fixed --showtime not accounting for addons Performance: Introduced cache for followAllReferences() calls Infrastructure & dependencies: Removed deprecated support for builds with Qt5. Added make variables CXXOPTS and LDOPTS to extend existing CXXFLAGS and LDFLAGS. Added make variables CPPOPTS to extend existing CPPFLAGS. CPPFLAGS are not longer being passed to the linker command for cppcheck and testrunner. Updated Qt to 6.10.0 (official Windows release only). The official Windows binary is now built against Boost 1.89 for increased performance. Updated to simplecpp 1.6.2 The Visual Studio builds not longer set the WIN32 define. Added DISALLOW_PROCESS_EXECUTOR for building without fork(). |

Improved checking: constVariable; checking multidimensional arrays constVariablePointer; nested array access deallocuse Changed interface: SARIF output. Use --output-format=sarif to activate this. Add option --output-format=. Allowed formats are sarif and xml. Deprecations: The previously deprecated support for Python 2.7 has been removed. please use Python 3 instead. The maximum value for --max-ctu-depth is currently capped at 10. This limitation will be removed in a future release. Other: "missingInclude" is no longer implicitly enabled with "information" - you need to enable it explicitly now. Fixed checkers report when --addon=misra.py or --addon=misra.json is used. |
| Cppcheck 2.15.0 Aug 31, 2024 |
New checks: suspiciousFloatingPointCast flags unnecessary floating point casts that cause loss of precision GUI: Added misra/cert/autosar reports Fixed "Recheck" Add "inline suppressions" option in project file Make it possible to define extra defines when importing a project Changed interface: Added command-line option --cpp-header-probe (and --no-cpp-header-probe) to probe headers and extension-less files for Emacs marker (see https://trac.cppcheck.net/ticket/10692 for more details) Deprecations: Support for Python 2.7 has been deprecated (it went EOL in January 2020) and will be removed in Cppcheck 2.16 - please use Python 3.x instead. The already deprecated support for qmake will be removed in Cppcheck 2.16 - please use CMake instead. Other: Add support for 'CLICOLOR_FORCE'/'NO_COLOR' environment variables to force/disable ANSI color output for diagnostics. Add "remark comments" that can be used to generate reports with justifications for warnings The whole program analysis is now being executed when "--project" is being used. Improved import of Visual Studio projects, support shared items projects (*.vcxitems). |

Summary: Fixed 23 "crash" tickets Fixed 69 "false positive" tickets Fixed 36 "improve check" tickets New checks: eraseIteratorOutOfBounds: warns when erase() is called on an iterator that is out of bounds returnByReference: warns when a large class member is returned by value from a getter function GUI: -Make it possible to suppress warnings in all files in a folder Changed interface: Fixed crash with '--rule-file=' if some data was missing. '--rule-file' will now bail out if a rule could not be added or a file contains unexpected data. Add option '--check-version', you can use it to pin the cppcheck version in a script. Added '--template=simple'. It is expands to '{file}:{line}:{column}: {severity}:{inconclusive:inconclusive:} {message} [{id}]' without any additional location details. Removed deprecated platform type 'Unspecified'. Please use 'unspecified' instead. Add --file-filter=- option that reads file filters from stdin. Added for a plugin. |

New checks: uselessOverride finds overriding functions that either duplicate code from or delegate back to the base class implementation knownPointerToBool finds pointer to bool conversions that are always true or false Improved checking: truncLongCastAssignment and truncLongCastReturn check additional types, including float/double/long double duplInheritedMember also reports duplicated member functions constParameter*/constVariable* checks find more instances of pointers/references that can be const, e.g. when calling library functions GUI: Show in statistics which checkers have been activated in latest analysis Make it more visible if there has been critical errors that caused checkers to be skipped Changed interface: Write how many checkers was activated after a run Added --checkers-report that can be used to generate a report in a file that shows what checkers was activated and disabled |

Improved checking: Improve useStlAlgorithm check to handle many more conditions in the loop for any_of, all_of and none_of algorithms ValueFlow can evaluate the return value of functions even when conditionals are used ValueFlow will now forward the container sizes being returned from a function ValueFlow can infer possible values from possible symbolic values Improve valueflow after pushing to container GUI: The platform type 'Unspecified' within .cppcheck projects has been deprecated and will be removed in Cppcheck 2.14. Please use 'unspecified' instead. Do not replace relative paths with absolute paths in suppressions in the project file dialog |
