Release 1.2.1 is a bug fix release for 1.2.0.
Added PHP API with limited support, documentation and testing. For more information please see the src/php4/README in your download package.
Fix a bug in the query processor where queries that combined an equality and a presence lookup, in that order, would not optimize away the presence lookup. [#9437]
Fix a bug where substring queries for values with more than five characters caused an assertion failure. [9504]
Fix a bug where a substring search for 3-character string did not normalize the string. [#9573]
                    Fix a bug where Python failed to find a function
                    overload.  This occurred in all overloaded
                    XmlContainer methods that take a
                    DbTxn * as their first argument, notable
                    XmlContainer::deleteDocument()
                    and
                    XmlContainer::queryWithXPath().
                    This problem would only occur in release 1.2.0 [#9443]
