Shared libraries are now versioned by ABI: 3.1 instead of 3.1.0 etc. Threading behavior is now documented and can be queried. Configuring with --with-tr1=boost will cause the BOOST shared_ptr to be used. Read-only transactions are now supported. binarystring::str() is no longer cached and no longer returns a reference. It is now possible to check whether a prepared statement has been defined. Results now have an iterator as well as const_iterator. robusttransaction logic was rewritten and may actually do its job now. Build fixes were made for Solaris, Red Hat, and Visual C++.
