  Finds cases where an integer expression is added to or subtracted from the
  result of a memory allocation function (``malloc()``, ``calloc()``,
  ``realloc()``, ``alloca()``) instead of its argument.

- New :doc:`bugprone-reserved-identifier
  <clang-tidy/checks/bugprone-reserved-identifier>` check.

  Checks for usages of identifiers reserved for use by the implementation.

- New :doc:`cert-oop57-cpp
  <clang-tidy/checks/cert-oop57-cpp>` check.

  Flags use of the `C` standard library functions ``memset``, ``memcpy`` and
  ``memcmp`` and similar derivatives on non-trivial types.

- New :doc:`objc-dealloc-in-category
  <clang-tidy/checks/objc-dealloc-in-category>` check.

  Finds implementations of -dealloc in Objective-C categories.

- New :doc:`misc-no-recursion
  <clang-tidy/checks/misc-no-recursion>` check.

  Finds recursive functions and diagnoses them.

New check aliases
^^^^^^^^^^^^^^^^^

- New alias :doc:`cert-dcl37-c

  :doc:`bugprone-reserved-identifier
  <clang-tidy/checks/bugprone-reserved-identifier>` was added.

- New alias :doc:`cert-dcl51-cpp
  <clang-tidy/checks/cert-dcl51-cpp>` to

Changes in existing checks
^^^^^^^^^^^^^^^^^^^^^^^^^^

- Improved :doc:`readability-qualified-auto
  <clang-tidy/checks/readability-qualified-auto>` check now supports a 
  `AddConstToQualified` to enable adding ``const`` qualifiers to variables
  typed with ``auto *`` and ``auto &``.

- Improved :doc:`readability-redundant-string-init
  <clang-tidy/checks/readability-redundant-string-init>` check now supports a
  `StringNames` option enabling its application to custom string classes. The
  check now detects in class initializers and constructor initializers which
  are deemed to be redundant.
