On the SQL front here are the highlights:
* Nested complex types support
That is multi dimensional arrays, rows in rows, arrays in rows etc...
JDBC is also supporting this.
* NVL2, HEXTORAW functions
* Allow scalar functions returning arrays in the FROM clause
That means you have defacto another way to write complex
table function
* anonymous blocks with rollback.
Anonymous blocks are now compiled in an autonomous transactions.
That means you can rollback within the block beyond the beginning of
the block.
