Improvements to clang-tidy
--------------------------

- New :doc:`abseil-duration-division
  <clang-tidy/checks/abseil-duration-division>` check.

  Checks for uses of ``absl::Duration`` division that is done in a
  floating-point context, and recommends the use of a function that
  returns a floating-point value.

- New :doc:`abseil-faster-strsplit-delimiter
  <clang-tidy/checks/abseil-faster-strsplit-delimiter>` check.

  Finds instances of ``absl::StrSplit()`` or ``absl::MaxSplits()`` where the
  delimiter is a single character string literal and replaces with a character.

- New :doc:`abseil-no-internal-dependencies
  <clang-tidy/checks/abseil-no-internal-dependencies>` check.
  
  Gives a warning if code using Abseil depends on internal details.

- New :doc:`abseil-no-namespace
  <clang-tidy/checks/abseil-no-namespace>` check.

  Ensures code does not open ``namespace absl`` as that violates Abseil's
  compatibility guidelines.

- New :doc:`abseil-redundant-strcat-calls
  <clang-tidy/checks/abseil-redundant-strcat-calls>` check.

  Suggests removal of unnecessary calls to ``absl::StrCat`` when the result is
  being passed to another ``absl::StrCat`` or ``absl::StrAppend``.

- New :doc:`abseil-str-cat-append
  <clang-tidy/checks/abseil-str-cat-append>` check.

  Flags uses of ``absl::StrCat()`` to append to a ``std::string``. Suggests 
  ``absl::StrAppend()`` should be used instead.

- New :doc:`readability-magic-numbers
  <clang-tidy/checks/readability-magic-numbers>` check.

  Detects usage of magic numbers, numbers that are used as literals instead of
  introduced via constants or symbols.
