- Update to version 3.21.0 * Take advantage of the atomic-write capabilities in the F2FS filesystem when available, for greatly reduced transaction overhead. This currently requires the SQLITE_ENABLE_BATCH_ATOMIC_WRITE compile-time option. * Allow ATTACH and DETACH commands to work inside of a transaction. * Allow WITHOUT ROWID virtual tables to be writable if the PRIMARY KEY contains exactly one column. * The "fsync()" that occurs after the header is written in a WAL reset now uses the sync settings for checkpoints. This means it will use a "fullfsync" on macs if PRAGMA checkpoint_fullfsync set on. * The sqlite3_sourceid() function tries to detect if the source code has been modified from what is checked into version control and if there are modifications, the last four characters of the version hash are shown as "alt1" or "alt2". The objective is to detect accidental and/or careless edits. A forger can subvert this feature. * Improved de-quoting of column names for CREATE TABLE AS statements with an aggregate query on the right-hand side. * Fewer "stat()" system calls issued by the unix VFS. * Enhanced the LIKE optimization so that it works with an ESCAPE clause. * Enhanced PRAGMA integrity_check and PRAGMA quick_check to detect obscure row corruption that they were formerly missing. Also update both pragmas so that they return error text rather than SQLITE_CORRUPT when encountering corruption in records. * The query planner now prefers to implement FROM-clause

- Update to 3.19.0 * The SQLITE_READ authorizer callback is invoked once with a column name that is an empty string for every table referenced in a query from which no columns are extracted. * When using an index on an expression, try to use expression values already available in the index, rather than loading the original columns and recomputing the expression. * Enhance the flattening optimization so that it is able to flatten views on the right-hand side of a LEFT JOIN. * Use replace() instead of char() for escaping newline and carriage-return characters embedded in strings in the .dump output from the command-line shell. * Avoid unnecessary foreign key processing in UPDATE statements that do not touch the columns that are constrained by the foreign keys. * On a DISTINCT query that uses an index, try to skip ahead to the next distinct entry using the index rather than stepping through rows, when an appropriate index is available. * Avoid unnecessary invalidation of sqlite3_blob handles when making changes to unrelated tables. * Transfer any terms of the HAVING clause that use only columns mentioned in the GROUP BY clause over to the WHERE clause for faster processing. * Reuse the same materialization of a VIEW if that VIEW appears more than once in the same query. * Enhance PRAGMA integrity_check so that it identifies tables that have two or more rows with the same rowid. * Enhance the FTS5 query syntax so that column filters may be applied to arbitrary expressions. * Enhance the json_extract() function to cache and

- Update to 3.18.0 * Added the PRAGMA optimize command * The SQLite version identifier returned by the sqlite_source_id() SQL function and the sqlite3_sourceid() C API and found in the SQLITE_SOURCE_ID macro is now a 64-digit SHA3-256 hash instead of a 40-digit SHA1 hash. * Added the json_patch() SQL function to the JSON1 extension. * Enhance the LIKE optimization so that it works for arbitrary expressions on the left-hand side as long as the LIKE pattern on the right-hand side does not begin with a digit or minus sign. * Added the sqlite3_set_last_insert_rowid() interface and use the new interface in the FTS3, FTS4, and FTS5 extensions to ensure that the sqlite3_last_insert_rowid() interface always returns reasonable values. * Enhance PRAGMA integrity_check and PRAGMA quick_check so that they verify CHECK constraints. * Enhance the query plans for joins to detect empty tables early and halt without doing unnecessary work. * Enhance the sqlite3_mprintf() family of interfaces and the printf SQL function to put comma separators at the thousands marks for integers, if the "," format modifier is used in between the "%" and the "d" (example: "%,d"). * Added the -DSQLITE_MAX_MEMORY=N compile-time option. * Added the .sha3sum dot-command and the .selftest dot-command to the command-line shell * Begin enforcing SQLITE_LIMIT_VDBE_OP. This can be used, for example, to prevent excessively large prepared statements in systems that accept SQL queries from untrusted users. * Various performance improvements. * Ensure that indexed expressions with collating sequences are

- Update to 3.17.0 * Approximately 25% better performance from the R-Tree extension. * Add the SQLITE_DEFAULT_LOOKASIDE compile-time option. * Increase the default lookaside size from 512,125 to 1200,100 as this provides better performance while only adding 56KB of extra memory per connection. * Use compiler built-ins __builtin_sub_overflow(), __builtin_add_overflow(), and __builtin_mul_overflow() when available. * Added the SQLITE_ENABLE_NULL_TRIM compile-time option, which can result in significantly smaller database files for some applications, at the risk of being incompatible with older versions of SQLite. * Change SQLITE_DEFAULT_PCACHE_INITSZ from 100 to 20, for improved performance. * Added the SQLITE_UINT64_TYPE compile-time option as an analog to SQLITE_INT64_TYPE. * Perform some UPDATE operations in a single pass instead of in two passes. * Enhance the session extension to support WITHOUT ROWID tables. * Fixed performance problems and potential stack overflows when creating views from multi-row VALUES clauses with hundreds of thousands of rows. * Added the sha1.c extension. * In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". * Enhance the SQLITE_DIRECT_OVERFLOW_READ option so that it works in WAL mode as long as the pages being read are not in the WAL file.
