SQLite Release 3.45.0 On 2024-01-15

  1. Added the SQLITE_RESULT_SUBTYPE property for application-defined SQL functions. All application defined SQL functions that invokes sqlite3_result_subtype() must be registered with this new property. Failure to do so might cause the call to sqlite3_result_subtype() to behave as a no-op. Compile with -DSQLITE_STRICT_SUBTYPE=1 to cause an SQL error to be raised if a function that is not SQLITE_RESULT_SUBTYPE tries invokes sqlite3_result_subtype(). The use of -DSQLITE_STRICT_SUBTYPE=1 is a recommended compile-time option for every application that makes use of subtypes.
  2. Enhancements to the JSON SQL functions:
    1. All JSON functions are rewritten to use a new internal parse tree format called JSONB. The new parse-tree format is serializable and hence can be stored in the database to avoid unnecessary re-parsing whenever the JSON value is used.
    2. New versions of JSON-generating functions generate binary JSONB instead of JSON text.
    3. The json_valid() function adds an optional second argument that specifies what it means for the first argument to be "well-formed".
  3. Add the FTS5 tokendata option to the FTS5 virtual table.
  4. The SQLITE_DIRECT_OVERFLOW_READ optimization is now enabled by default. Disable it at compile-time using -DSQLITE_DIRECT_OVERFLOW_READ=0.
  5. Query planner improvements:
    1. Do not allow the transitive constraint optimization to trick the query planner into using a range constraint when a better equality constraint is available. (Forum post 2568d1f6e6.)
    2. The query planner now does a better job of disregarding indexes that ANALYZE identifies as low-quality. (Forum post 6f0958b03b.)
  6. Increase the default value for SQLITE_MAX_PAGE_COUNT from 1073741824 to 4294967294.
  7. Enhancements to the CLI:
    1. Improvements to the display of UTF-8 content on Windows
    2. Automatically detect playback of ".dump" scripts and make appropriate changes to settings such as ".dbconfig defensive off" and ".dbconfig dqs_dll on".


  8. SQLITE_SOURCE_ID: 2024-01-15 17:01:13 1066602b2b1976fe58b5150777cced894af17c803e068f5918390d6915b46e1d
  9. SHA3-256 for sqlite3.c: f56d8e5e8c61d87b957f1cc60b3042c134d7bc0ca3aba002e6999e8f0af310a3
