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.

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
