SQLite 3.23.0 (64-bit)

What's new in this version:

- Add the sqlite3_serialize() and sqlite3_deserialize() interfaces when the SQLITE_ENABLE_DESERIALIZE compile-time option is used
- Recognize TRUE and FALSE as constants. (For compatibility, if there exist columns named "true" or "false", then the identifiers refer to the columns rather than Boolean constants)
- Support operators IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE
- Added the SQLITE_DBSTATUS_CACHE_SPILL option to sqlite3_db_status() for reporting the number of cache spills that have occurred
- The "alternate-form-2" flag ("!") on the built-in printf implementation now causes string substitutions to measure the width and precision in characters instead of bytes
- If the xColumn method in a virtual table implementation returns an error message using sqlite3_result_error() then give that error message preference over internally-generated messages
- Added the -A command-line option to the CLI to make it easier to manage SQLite Archive files
- Add support for INSERT OR REPLACE, INSERT OR IGNORE, and UPDATE OR REPLACE in the Zipfile virtual table
- Enhance the sqlite3changeset_apply() interface so that it is hardened against attacks from deliberately corrupted changeset objects
- Added the sqlite3_normalize() extension function

Query optimizer enhancements:
- Improve the omit-left-join optimization so that it works in cases where the right-hand table is UNIQUE but not necessarily NOT NULL
- Improve the push-down optimization so that it works for many LEFT JOINs
- Add the LEFT JOIN strength reduction optimization that converts a LEFT JOIN into an ordinary JOIN if there exist terms in the WHERE clause that would prevent the extra all-NULL row of the LEFT JOIN from appearing in the output set
- Avoid unnecessary writes to the sqlite_sequence table when an AUTOINCREMENT table is updated with an rowid that is less than the maximum

Bug fixes:
- Fix the parser to accept valid row value syntax
- Fix the query planner so that it takes into account dependencies in the arguments to table-valued functions in subexpressions in the WHERE clause
- Fix incorrect result with complex OR-connected WHERE and STAT4
- Fix potential corruption in indexes on expressions due to automatic datatype conversions
- Assertion fault in FTS4
- Incorrect result on the less-than operator in row values
- Always interpret non-zero floating-point values as TRUE, even if the integer part is zero
- Fix an issue in the fsdir(PATH) table-valued function to the fileio.c extension, that caused a segfault if the fsdir() table was used as the inner table of a join
- Issue an error rather instead of an assertion-fault or null-pointer dereference when the sqlite_master table is corrupted so that the sqlite_sequence table root page is really a btree-index page
- Fix the ANALYZE command so that it computes statistics on tables whose names begin with "sqlite"

Additional fixes for issues detected by OSSFuzz:
- Fix a possible infinite loop on VACUUM for corrupt database files
- Disallow parameters in the WITH clause of triggers and views
- Fix a potential memory leak in row value processing
- Improve the performance of the replace() SQL function for cases where there are many substitutions on megabyte-sized strings, in an attempt to avoid OSSFuzz timeouts during testing
- Provide an appropriate error message when the sqlite_master table contains a CREATE TABLE AS statement. Formerly this caused either an assertion fault or null pointer dereference. Problem found by OSSFuzz on the GDAL project
- Incorrect assert() statement removed
- Fix a problem with using the LIKE optimization on an INTEGER PRIMARY KEY
