## Change Log

### Review Version

Initial review version, for the review conducted from 7th December 2007 to 16th December 2007.

### 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.

### 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.

### Boost 1.37.0

- Rename overload of `emplace` with hint, to `emplace_hint` as specified in 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.

### Boost 1.38.0

- Use `boost::swap`.
- 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.
- Ticket 1710: Use a larger prime number list. Thanks to Thorsten Ottosen and Hervé Brönnimann.
- Use 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).
