SQLite (32-bit)

What's new in this version:

- Added the VACUUM INTO command
- Issue an SQLITE_WARNING message on the error log if a double-quoted string literal is used.
- The sqlite3_normalized_sql() interface works on any prepared statement created using sqlite3_prepare_v2() or sqlite3_prepare_v3(). It is no longer necessary to use sqlite3_prepare_v3() with SQLITE_PREPARE_NORMALIZE in order to use sqlite3_normalized_sql()
- Added the remove_diacritics=2 option to FTS3 and FTS5
- Added the SQLITE_PREPARE_NO_VTAB option to sqlite3_prepare_v3(). Use that option to prevent circular references to shadow tables from causing resource leaks

Enhancements to the sqlite3_deserialize() interface:
- Add the SQLITE_FCNTL_SIZE_LIMIT file-control for setting an upper bound on the size of the in-memory database created by sqlite3_deserialize. The default upper bound is 1GiB, or whatever alternative value is specified by sqlite3_config(SQLITE_CONFIG_MEMDB_MAXSIZE) and/or SQLITE_MEMDB_DEFAULT_MAXSIZE.
- Honor the SQLITE_DESERIALIZE_READONLY flag, which was previously described in the documentation, but was previously a no-op
- Enhance the "deserialize" command of the TCL Interface to give it new "--maxsize N" and "--readonly BOOLEAN" options

Enhancements to the CLI, mostly to support testing and debugging of the SQLite library itself:
- Add support for ".open --hexdb". The "dbtotxt" utility program used to generate the text for the "hexdb" is added to the source tree
- Add support for the "--maxsize N" option on ".open --deserialize"
- Add the "--memtrace" command-line option, to show all memory allocations and deallocations
- Add the ".eqp trace" option on builds with SQLITE_DEBUG, to enable bytecode program listing with indentation and PRAGMA vdbe_trace all in one step
- Add the ".progress" command for accessing the sqlite3_progress_handler() interface
- Add the "--async" option to the ".backup" command
- Add options "--expanded", "--normalized", "--plain", "--profile", "--row", "--stmt", and "--close" to the ".trace" command
- Omit deprecated PRAGMA statements when compiling with SQLITE_OMIT_DEPRECATED
- Increased robustness against malicious SQL that is run against a maliciously corrupted database

Bug fixes:
- Do not use a partial index to do a table scan on an IN operator
- Fix the query flattener so that it works on queries that contain subqueries that use window functions
- Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers
- Fix a parser bug that prevented the use of parentheses around table-valued functions
- Fix a problem with the OR optimization on indexes on expressions
- Fix a problem with the LEFT JOIN strength reduction optimization in which the optimization was being applied inappropriately due to an IS NOT NULL operator
- Fix the REPLACE command so that it is no longer able to sneak a NULL value into a NOT NULL column even if the NOT NULL column has a default value of NULL
- Fix a problem with the use of window functions used within correlated subqueries
- Fix the ALTER TABLE RENAME COLUMN command so that it works for tables that have redundant UNIQUE constraints
- Fix a bug that caused zeroblob values to be truncated when inserted into a table that uses an expression index
