 Improvements to clang-query
 ---------------------------
 
-- A new command line parameter ``--preload`` was added to
-  run commands from a file and then start the interactive interpreter.
-
-- The command ``q`` can was added as an alias for ``quit`` to exit the
-  ``clang-query`` interpreter.
-
-- It is now possible to bind to named values (the result of ``let``
-  expressions). For example:
-
-  .. code-block:: none
-
-    let fn functionDecl()
-    match fn.bind("foo")
-
-- It is now possible to write comments in ``clang-query`` code. This
-  is primarily useful when using script-mode. Comments are all content
-  following the ``#`` character on a line:
-
-  .. code-block:: none
-
-    # This is a comment
-    match fn.bind("foo") # This is a trailing comment
-
-- The new ``set print-matcher true`` command now causes ``clang-query`` to
-  print the evaluated matcher together with the resulting bindings.
-
-- A new output mode ``detailed-ast`` was added to ``clang-query``. The
-  existing ``dump`` output mode is now a deprecated alias
-  for ``detailed-ast``
-
-- Output modes can now be enabled or disabled non-exclusively.  For example,
-
-  .. code-block:: none
-
-    # Enable detailed-ast without disabling other output, such as diag
-    enable output detailed-ast
-    m functionDecl()
-
-    # Disable detailed-ast only
-    disable output detailed-ast
-    m functionDecl()

 Improvements to Clang's diagnostics
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-- ``-Wextra-semi-stmt`` is a new diagnostic that diagnoses extra semicolons,
-  much like ``-Wextra-semi``. This new diagnostic diagnoses all *unnecessary*
-  null statements (expression statements without an expression), unless: the
-  semicolon directly follows a macro that was expanded to nothing or if the
-  semicolon is within the macro itself. This applies to macros defined in system
-  headers as well as user-defined macros.

-      #define NULLMACRO(varname)

-
-        NULLMACRO(v2); // ignored, NULLMACRO expanded to nothing.
-      }
-
-- ``-Wempty-init-stmt`` is a new diagnostic that diagnoses empty init-statements
-  of ``if``, ``switch``, ``range-based for``, unless: the semicolon directly
-  follows a macro that was expanded to nothing or if the semicolon is within the
-  macro itself (both macros from system headers, and normal macros). This
-  diagnostic is in the ``-Wextra-semi-stmt`` group and is enabled in
-  ``-Wextra``.

-- The internals of libc++ include directory detection on MacOS have changed.
-  Instead of running a search based on the ``-resource-dir`` flag, the search
-  is now based on the path of the compiler in the filesystem. The default
-  behaviour should not change. However, if you override ``-resource-dir``
-  manually and rely on the old behaviour you will need to add appropriate
-  compiler flags for finding the corresponding libc++ include directory.
 
 New Compiler Flags

-- ``-fprofile-filter-files=[regexes]`` and ``-fprofile-exclude-files=[regexes]``.

 Undefined Behavior Sanitizer (UBSan)
 ------------------------------------
 
-* The Implicit Conversion Sanitizer (``-fsanitize=implicit-conversion``) group
-  was extended. One more type of issues is caught - implicit integer sign change.
-  (``-fsanitize=implicit-integer-sign-change``).
-  This makes the Implicit Conversion Sanitizer feature-complete,
-  with only missing piece being bitfield handling.
-  While there is a ``-Wsign-conversion`` diagnostic group that catches this kind
-  of issues, it is both noisy, and does not catch **all** the cases.

-        (void)consume((unsigned int)val); // OK, the conversion is explicit.
-      }
-
-  Like some other ``-fsanitize=integer`` checks, these issues are **not**
-  undefined behaviour. But they are not *always* intentional, and are somewhat
-  hard to track down. This group is **not** enabled by ``-fsanitize=undefined``,
-  but the ``-fsanitize=implicit-integer-sign-change`` check
-  is enabled by ``-fsanitize=integer``.

 API Changes
 -----------
-- Building libc++ for Mac OSX 10.6 is not supported anymore.
-- Starting with LLVM 8.0.0, users that wish to link together translation units
-  built with different versions of libc++'s headers into the same final linked
-  image MUST define the _LIBCPP_HIDE_FROM_ABI_PER_TU macro to 1 when building
-  those translation units. Not defining _LIBCPP_HIDE_FROM_ABI_PER_TU to 1 and
-  linking translation units built with different versions of libc++'s headers
-  together may lead to ODR violations and ABI issues. On the flipside, code
-  size improvements should be expected for everyone not defining the macro.
-- Starting with LLVM 8.0.0, std::dynarray has been removed from the library.
-  std::dynarray was a feature proposed for C++14 that was pulled from the
-  Standard at the last minute and was never standardized. Since there are no
-  plans to standardize this facility it is being removed.
-- Starting with LLVM 8.0.0, std::bad_array_length has been removed from the
-  library. std::bad_array_length was a feature proposed for C++14 alongside
-  std::dynarray, but it never actually made it into the C++ Standard. There
-  are no plans to standardize this feature at this time. Formally speaking,
-  this removal constitutes an ABI break because the symbols were shipped in
-  the shared library. However, on macOS systems, the feature was not usable
-  because it was hidden behind availability annotations. We do not expect
-  any actual breakage to happen from this change.

-* lld can now automatically import data variables from DLLs without the

-
-* lld can now use existing normal MinGW sysroots with import libraries and
-  CRT startup object files for GNU binutils. lld can handle most object
-  files produced by GCC, and thus works as a drop-in replacement for
-  ld.bfd in such environments. (There are known issues with linking crtend.o
-  from GCC in setups with DWARF exceptions though, where object files are
