OK, clang-tidy summary of changes from 3.6.2 final:

Added new checks:
  * google-global-names-in-headers: flag global namespace pollution in
header files.
  * misc-assert-side-effect: detects `assert()` conditions with side
effects which can cause different behavior in debug / release builds.
  * misc-assign-operator-signature: finds declarations of assign operators
with the wrong return and/or argument types.
  * misc-inaccurate-erase: warns when some elements of a container are not
removed due to using the `erase()` algorithm incorrectly.
  * misc-inefficient-algorithm: warns on inefficient use of STL algorithms
on associative containers.
  * misc-macro-parentheses: finds macros that can have unexpected behavior
due to missing parentheses.
  * misc-macro-repeated-side-effects: checks for repeated argument with
side effects in macros.
  * misc-noexcept-move-constructor: flags user-defined move constructors
and assignment operators not marked with `noexcept` or marked with
`noexcept(expr)` where `expr` evaluates to `false` (but is not a `false`
literal itself).
  * misc-static-assert: replaces `assert()` with `static_assert()` if the
condition is evaluatable at compile time.
  * readability-container-size-empty: checks whether a call to the `size()`
method can be replaced with a call to `empty()`.
  * readability-else-after-return: flags conditional statements having the
`else` branch, when the `true` branch has a `return` as the last statement.
  * readability-redundant-string-cstr: finds unnecessary calls to
`std::string::c_str()`.
  * readability-shrink-to-fit: replaces copy and swap tricks on shrinkable
containers with the `shrink_to_fit()` method call.
  * readability-simplify-boolean-expr: looks for boolean expressions
involving boolean constants and simplifies them to use the appropriate
boolean expression directly (`if (x == true) ... -> if (x)`, etc.)

+ minor fixes and improvements
