## SQLite Release 3.6.15 On 2009-06-15

1. Refactor the internal representation of SQL expressions so that they use less memory on embedded platforms.
2. Reduce the amount of stack space used
3. Fix an 64-bit alignment bug on HP/UX and Sparc
4. The sqlite3_create_function() family of interfaces now return SQLITE_MISUSE instead of SQLITE_ERROR when passed invalid parameter combinations.
5. When new tables are created using CREATE TABLE ... AS SELECT ... the datatype of the columns is the simplified SQLite datatype (TEXT, INT, REAL, NUMERIC, or BLOB) instead of a copy of the original datatype from the source table.
6. Resolve race conditions when checking for a hot rollback journal.
7. The sqlite3_shutdown() interface frees all mutexes under windows.
8. Enhanced robustness against corrupt database files
9. Continuing improvements to the test suite and fixes to obscure bugs and inconsistencies that the test suite improvements are uncovering.
