---------------
* The API has been streamlined: ``make_bond()`` is now the primary method of
constructing ``Bond`` objects, independently of the interpreter language.
The old language constructors are still supported, but are deprecated and
will be removed in a future release.
* All functions/objects/methods are now documented with docstrings.
* Bond initialization errors, especially errors related to missing
dependencies, are now much easier to understand.
* Serialization exceptions on the remote side have been renamed to
``_BOND_SerializationException`` for consistency with other languages.
* JavaScript/Node.js support was previously limited to versions >= 0.10. Any
version of Node.js starting with 0.6.12 is now supported.
* PHP support was previously limited to versions >= 5.6. Any version of PHP
starting with 5.3 is now supported.
* A Perl dependency on ``IO::String`` was previously missing, and has now been
correctly documented.
