Merge branch 'develop'

They are being removed from the standard in C++17, and were never really
required.

@@ -269,4 +269,38 @@ C++11 support has resulted in some breaking changes:
 * Fix potential overflow when calculating number of buckets to allocate
   ([@https://github.com/boostorg/unordered/pull/4 GitHub #4]).
 
+[h2 Boost 1.62.0]
+
+* Remove use of deprecated `boost::iterator`.
+* Remove `BOOST_NO_STD_DISTANCE` workaround.
+* Remove `BOOST_UNORDERED_DEPRECATED_EQUALITY` warning.
+* Simpler implementation of assignment, fixes an exception safety issue
+  for `unordered_multiset` and `unordered_multimap`. Might be a little slower.
+* Stop using return value SFINAE which some older compilers have issues
+  with.
+
+[h2 Boost 1.63.0]
+
+* Check hint iterator in `insert`/`emplace_hint`.
+* Fix some warnings, mostly in the tests.
+* Manually write out `emplace_args` for small numbers of arguments -
+  should make template error messages a little more bearable.
+* Remove superfluous use of `boost::forward` in emplace arguments,
+  which fixes emplacing string literals in old versions of Visual C++.
+* Fix an exception safety issue in assignment. If bucket allocation
+  throws an exception, it can overwrite the hash and equality functions while
+  leaving the existing elements in place. This would mean that the function
+  objects wouldn't match the container elements, so elements might be in the
+  wrong bucket and equivalent elements would be incorrectly handled.
+* Various reference documentation improvements.
+* Better allocator support ([ticket 12459]).
+* Make the no argument constructors implicit.
+* Implement missing allocator aware constructors.
+* Fix assigning the hash/key equality functions for empty containers.
+* Remove unary/binary_function from the examples in the documentation.
+  They are removed in C++17.
+* Support 10 constructor arguments in emplace. It was meant to support up to 10
+  arguments, but an off by one error in the preprocessor code meant it only
+  supports up to 10.
