arguments. So when porting a query to C++, remove all instances of trailing
comma (otherwise C++ compiler will just complain about "expected expression").
-Improvements to include-cleaner
--------------------------------
-- Deprecated the ``-insert`` and ``-remove`` command line options, and added
- the ``-disable-remove`` and ``-disable-insert`` command line options as
- replacements. The previous command line options were confusing because they
- did not imply the default state of the option (which is inserts and removes
- being enabled). The new options are easier to understand the semantics of.
-
Improvements to clang-tidy
--------------------------
-- Changed the :program:`check_clang_tidy.py` tool to use FileCheck's
- ``--match-full-lines`` instead of ``strict-whitespace`` for ``CHECK-FIXES``
- clauses. Added a ``--match-partial-fixes`` option to keep previous behavior on
- specific tests. This may break tests for users with custom out-of-tree checks
- who use :program:`check_clang_tidy.py` as-is.
-
-- Improved :program:`clang-tidy-diff.py` script. Add the `-warnings-as-errors`
- argument to treat warnings as errors.
-
-- Improved :program:`clang-tidy` to show `CheckOptions` only for checks enabled
- in `Checks` when running ``--dump-config``.
-
-- Fixed bug in :program:`clang-tidy` by which `HeaderFilterRegex` did not take
- effect when passed via the `.clang-tidy` file.
-
-- Fixed bug in :program:`run_clang_tidy.py` where the program would not
- correctly display the checks enabled by the top-level `.clang-tidy` file.
-
New checks
^^^^^^^^^^
-- New :doc:`bugprone-capturing-this-in-member-variable
- <clang-tidy/checks/bugprone/capturing-this-in-member-variable>` check.
-
- Finds lambda captures and ``bind`` function calls that capture the ``this``
- pointer and store it as class members without handle the copy and move
- constructors and the assignments.
-
-- New :doc:`bugprone-misleading-setter-of-reference
- <clang-tidy/checks/bugprone/misleading-setter-of-reference>` check.

- reference member of the same class with the pointed value.
-
-- New :doc:`bugprone-unintended-char-ostream-output
- <clang-tidy/checks/bugprone/unintended-char-ostream-output>` check.
-
- Finds unintended character output from ``unsigned char`` and ``signed char``
- to an ``ostream``.
-
-- New :doc:`cppcoreguidelines-use-enum-class
- <clang-tidy/checks/cppcoreguidelines/use-enum-class>` check.

-
-- New :doc:`portability-avoid-pragma-once
- <clang-tidy/checks/portability/avoid-pragma-once>` check.
-
- Finds uses of ``#pragma once`` and suggests replacing them with standard
- include guards (``#ifndef``/``#define``/``#endif``) for improved portability.
-
-- New :doc:`readability-ambiguous-smartptr-reset-call
- <clang-tidy/checks/readability/ambiguous-smartptr-reset-call>` check.
-
- Finds potentially erroneous calls to ``reset`` method on smart pointers when
- the pointee type also has a ``reset`` method.
-
-- New :doc:`readability-use-concise-preprocessor-directives
- <clang-tidy/checks/readability/use-concise-preprocessor-directives>` check.
-
- Finds uses of ``#if`` that can be simplified to ``#ifdef`` or ``#ifndef`` and,

- or ``#elifndef``.
