Release Notes: This release has minor updates. Most of the changes are for compatibility with newer compilers, C++11, and different operating systems. The updates also include support for the REPEATABLE READ isolation level.
Release Notes: The theme for 4.0 is simplicity, but there have been many other improvements as well. At last, there's a viable Visual C++ build.
Release Notes: 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++.
