SQLite Release 3.34.0 On 2020-12-01

Added the sqlite3_txn_state() interface for reporting on the current transaction state of the database connection. Improved error messages on CHECK constraint failures. CLI enhancements: The .read dot-command now accepts a pipeline in addition to a filename. Query planner improvements: Improved estimates for the cost of running a DISTINCT operator. When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. Hashes: SQLITE_SOURCE_ID: pending SHA3-256 for sqlite3.c: pending
