-  ``reset()`` calls on moved-from ``std::optional`` and ``std::any`` objects,
-  similarly to smart pointers.

-  fix false positive that floating point variable is only used in increment
-  expression.
-
-- Improved :doc:`cppcoreguidelines-avoid-const-or-ref-data-members
-  <clang-tidy/checks/cppcoreguidelines/avoid-const-or-ref-data-members>` check to
-  avoid false positives when detecting a templated class with inheritance.
-
-- Improved :doc:`cppcoreguidelines-init-variables
-  <clang-tidy/checks/cppcoreguidelines/init-variables>` check by fixing the
-  insertion location for function pointers.
-
-- Improved :doc:`cppcoreguidelines-prefer-member-initializer
-  <clang-tidy/checks/cppcoreguidelines/prefer-member-initializer>` check to
-  avoid false positive when member initialization depends on a structured

-
-- Fixed :doc:`cppcoreguidelines-pro-type-union-access

-  report a location even when the member location is not valid.
-
-- Improved :doc:`misc-definitions-in-headers
-  <clang-tidy/checks/misc/definitions-in-headers>` check by rewording the

-
-- Improved :doc:`misc-redundant-expression
-  <clang-tidy/checks/misc/redundant-expression>` check by extending the
-  checker to detect floating point and integer literals in redundant

-  false positive for C++23 deducing this.
-
-- Improved :doc:`misc-use-internal-linkage
-  <clang-tidy/checks/misc/use-internal-linkage>` check to insert ``static``
-  keyword before type qualifiers such as ``const`` and ``volatile`` and fix
-  false positives for function declaration without body and fix false positives

-
-- Improved :doc:`modernize-use-std-format
-  <clang-tidy/checks/modernize/use-std-format>` check to support replacing

-
-- Improved :doc:`modernize-use-std-print
-  <clang-tidy/checks/modernize/use-std-print>` check to support replacing

-  ``find()`` case.
-
-- Improved :doc:`readability-enum-initial-value
-  <clang-tidy/checks/readability/enum-initial-value>` check by only issuing
-  diagnostics for the definition of an ``enum``, by not emitting a redundant
