hamsterdb Embedded Database 1.1.1 released

This release fixes a few minor bugs and adds a performance for In-Memory Databases: Users can now request a pointer to the stored record data by specifying the flag HAM_DIRECT_ACCES to ham_find, ham_cursor_find[_ex] and ham_cursor_move. Thus they can overwrite the record data without calling ham_insert or ham_cursor_overwrite. Also, a few flags were removed and the interface for ham_get_key_count was changed - please see the README.
