## Change Log

### Boost 1.33.0

- Initial Release

### Boost 1.33.1

- Fixed the points example, as pointed out by 沈慧峰.

### Boost 1.34.0

- Use declarations for standard classes, so that the library doesn't need to include all of their headers
- Deprecated the `<boost/functional/hash/*.hpp>` headers. Now a single header, <`boost/functional/hash.hpp`> is used.
- Add support for the `BOOST_HASH_NO_EXTENSIONS` macro, which disables the extensions to TR1.
- Minor improvements to the hash functions for floating point numbers.
- Update the portable example to hopefully be more generally portable.

### Boost 1.34.1

- Ticket 952: Suppress incorrect 64-bit warning on Visual C++.

### Boost 1.35.0

- Support for `long long`, `std::complex`.
- Improved algorithm for hashing floating point numbers:
  - Improved portablity, as described by Daniel Krügler in a post to the boost users list.
  - Fits more information into each combine loop, which can reduce the the number of times combine is called and hopefully give a better quality hash function.
  - Improved the algorithm for hashing floating point numbers.
  - On Cygwin use a binary hash function for floating point numbers, as Cygwin doesn't have decent floating point functions for `long double`.
  - Never uses `fpclass` which doesn't support `long double`.
  - Ticket 1064: Removed unnecessary use of `errno`.
- Explicitly overload for more built in types.
- Minor improvements to the documentation.
- A few bug and warning fixes:
  - Ticket 1509: Suppress another Visual C++ warning.
  - Some workarounds for the Sun compilers.

### Boost 1.36.0

- Stop using OpenBSD's dodgy `std::numeric_limits`.
- Using the boost typedefs for `long long` and `unsigned long long`.
- Move the extensions into their own header.
