## SQLite Release 3.29.0 On 2019-07-10

1. Added the SQLITE_DBCONFIG_DQS_DML and SQLITE_DBCONFIG_DQS_DDL actions to sqlite3_db_config() for activating and deactivating the double-quoted string literal misfeature. Both default to "on" for legacy compatibility, but developers are encouraged to turn them "off", perhaps using the -DSQLITE_DQS=0 compile-time option.
2. -DSQLITE_DQS=0 is now a recommended compile-time option.
3. Improvements to the query planner:
   1. Improved optimization of AND and OR operators when one or the other operand is a constant.
   2. Enhancements to the LIKE optimization for cases when the left-hand side column has numeric affinity.
4. Added the "sqlite_dbdata" virtual table for extracting raw low-level content from an SQLite database, even a database that is corrupt.
5. Enhancements to the CLI:
   1. Add the ".recover" command which tries to recover as much content as possible from a corrupt database file.
   2. Add the ".filectrl" command useful for testing.
   3. Add the long-standing ".testctrl" command to the ".help" menu.
   4. Added the ".dbconfig" command
