[section:changes Change Log]

 |

[h2 Review Version]
 | 
						|
 | 
						|
Initial review version, for the review conducted from 7th December 2007 to
 | 
						|
16th December 2007.
 | 
						|
 | 
						|
[h2 1.35.0 Add-on - 31st March 2008]
 | 
						|
 | 
						|
Unofficial release uploaded to vault, to be used with Boost 1.35.0. Incorporated
 | 
						|
many of the suggestions from the review.
 | 
						|
 | 
						|
* Improved portability thanks to Boost regression testing.
 | 
						|
* Fix lots of typos, and clearer text in the documentation.
 | 
						|
* Fix floating point to `std::size_t` conversion when calculating sizes from
 | 
						|
  the max load factor, and use `double` in the calculation for greater accuracy.
 | 
						|
* Fix some errors in the examples.
 | 
						|
 | 
						|
[h2 Boost 1.36.0]
 | 
						|
 | 
						|
First official release.
 | 
						|
 | 
						|
* Rearrange the internals.
 | 
						|
* Move semantics - full support when rvalue references are available, emulated
 | 
						|
  using a cut down version of the Adobe move library when they are not.
 | 
						|
* Emplace support when rvalue references and variadic template are available.
 | 
						|
* More efficient node allocation when rvalue references and variadic template
 | 
						|
  are available.
 | 
						|
* Added equality operators.
 | 
						|
 | 
						|
[h2 Boost 1.37.0]
 | 
						|
 | 
						|
* Rename overload of `emplace` with hint, to `emplace_hint` as specified in
 | 
						|
  [@http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2691.pdf n2691].
 | 
						|
* Provide forwarding headers at `<boost/unordered/unordered_map_fwd.hpp>` and
 | 
						|
  `<boost/unordered/unordered_set_fwd.hpp>`.
 | 
						|
* Move all the implementation inside `boost/unordered`, to assist
 | 
						|
  modularization and hopefully make it easier to track changes in subversion.
 | 
						|
 | 
						|
[h2 Boost 1.38.0]
 | 
						|
 | 
						|
* Use [@boost:/libs/utility/swap.html `boost::swap`].
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/2237 Ticket 2237]:
 | 
						|
  Document that the equality and inequality operators are undefined for two
 | 
						|
  objects if their equality predicates aren't equivalent. Thanks to Daniel
 | 
						|
  Krügler.
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/1710 Ticket 1710]: 
 | 
						|
  Use a larger prime number list. Thanks to Thorsten Ottosen and Hervé
 | 
						|
  Brönnimann.
 | 
						|
* Use
 | 
						|
  [@boost:/libs/type_traits/doc/html/boost_typetraits/category/alignment.html
 | 
						|
  aligned storage] to store the types. This changes the way the allocator is
 | 
						|
  used to construct nodes. It used to construct the node with two calls to
 | 
						|
  the allocator's `construct` method - once for the pointers and once for the
 | 
						|
  value. It now constructs the node with a single call to construct and
 | 
						|
  then constructs the value using in place construction.
 | 
						|
* Add support for C++0x initializer lists where they're available (currently
 | 
						|
  only g++ 4.4 in C++0x mode).
 | 
						|
 | 
						|
[h2 Boost 1.39.0]
 | 
						|
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/2756 Ticket 2756]: Avoid a warning
 | 
						|
  on Visual C++ 2009.
 | 
						|
* Some other minor internal changes to the implementation, tests and
 | 
						|
  documentation.
 | 
						|
* Avoid an unnecessary copy in `operator[]`.
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]: Fix length of
 | 
						|
  prime number list.
 | 
						|
 | 
						|
[h2 Boost 1.40.0]
 | 
						|
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]:
 | 
						|
  Store the prime list as a preprocessor sequence - so that it will always get
 | 
						|
  the length right if it changes again in the future.
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/1978 Ticket 1978]:
 | 
						|
  Implement `emplace` for all compilers.
 | 
						|
* Better configuration for C++0x features when the headers aren't available.
 | 
						|
* [@https://svn.boost.org/trac/boost/ticket/2908 Ticket 2908]:
 | 
						|
  Add explicit destructors to all containers.
 |
