SQLite Release 3.6.15 On 2009-06-15 (3.6.15)

• Refactor the internal representation of SQL expressions so that they use less memory on embedded platforms.
• Reduce the amount of stack space used
• Fix an 64-bit alignment bug on HP/UX and Sparc
• The sqlite3_create_function() family of interfaces now return SQLITE_MISUSE instead of SQLITE_ERROR when passed invalid parameter combinations.
• 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.
• Resolve race conditions when checking for a hot rollback journal.
• The sqlite3_shutdown() interface frees all mutexes under windows.
• Enhanced robustness against corrupt database files
• Continuing improvements to the test suite and fixes to obscure bugs and inconsistencies that the test suite improvements are uncovering.
