The default executor was changed to standalone to match other tools.

New cppcoreguidelines-avoid-const-or-ref-data-members check.

Warns when a struct or class uses const or reference (lvalue or rvalue) data members.

New check aliases ¶

New alias cert-msc54-cpp to bugprone-signal-handler was added.

Changes in existing checks ¶

Fixed a false positive in bugprone-assignment-in-if-condition check when there was an assignement in a lambda found in the condition of an if.
Improved bugprone-signal-handler check. Partial support for C++14 signal handler rules was added. Bug report generation was improved.
Fixed a false positive in cppcoreguidelines-pro-type-member-init when warnings would be emitted for uninitialized members of an anonymous union despite there being an initializer for one of the other members.
Improved modernize-use-emplace check.

The check now supports detecting inefficient invocations of push and push_front on STL-style containers and replacing them with emplace or emplace_front.

The check now supports detecting alias cases of push_back push and push_front on STL-style containers and replacing them with emplace_back, emplace or emplace_front.
Improved modernize-use-equals-default check.

The check now skips unions/union-like classes since in this case a default constructor with empty body is not equivalent to the explicitly defaulted one. The check also skips copy assignment operators with nonstandard return types. The check is restricted to c++11-or-later.
