* CVE-2019-9936, bsc#1130326: running fts5 prefix queries inside
a transaction could trigger a heap-based buffer over-read.
* CVE-2019-9937, bsc#1130325: interleaving reads and writes in a
single transaction with an fts5 virtual table will lead to a
NULL Pointer Dereference.
* Enhanced window functions
* Enhanced VACUUM INTO so that it works for read-only databases.
* New query optimizations.
* Added the sqlite3_value_frombind() API for determining if the
argument to an SQL function is from a bound parameter.
* Security and compatibilities enhancements to fts3_tokenizer().
* Improved robustness against corrupt database files.

- SQLite 3.26.0:
* Optimization: When doing an UPDATE on a table with indexes on
expressions, do not update the expression indexes if they do
not refer to any of the columns of the table being updated.
* Allow the xBestIndex() method of virtual table implementations
to return SQLITE_CONSTRAINT to indicate that the proposed query
plan is unusable and should not be given further consideration.
* Added the SQLITE_DBCONFIG_DEFENSIVE option which disables the
ability to create corrupt database files using ordinary SQL.
* Added support for read-only shadow tables when the
SQLITE_DBCONFIG_DEFENSIVE option is enabled.
* Added the PRAGMA legacy_alter_table command, which if enabled
causes the ALTER TABLE command to behave like older version of
SQLite (prior to version 3.25.0) for compatibility.
* Added PRAGMA table_xinfo that works just like PRAGMA table_info
except that it also shows hidden columns in virtual tables.
* Added the explain virtual table as a run-time loadable
extension.
* Add a limit counter to the query planner to prevent excessive
sqlite3_prepare() times for certain pathological SQL inputs.
* Added support for the sqlite3_normalized_sql() interface, when
compiling with SQLITE_ENABLE_NORMALIZE.
* Enhanced triggers so that they can use table-valued functions
that exist in schemas other than the schema where the trigger
is defined.
* Improvements to the ".help" command in the CLI.
* The SQLITE_HISTORY environment variable, if it exists,
specifies the name of the command-line editing history file.
* The --deserialize option associated with opening a new database
in the CLI cause the database file to be read into memory and
accessed using the sqlite3_deserialize() API. This simplifies
running tests on a database without modifying the file on disk.

- 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 3.19.2
* Fix a bug in the LEFT JOIN flattening optimization.
Ticket cad1ab4cb7b0fc.
* Fix more bugs in the LEFT JOIN flattening optimization.
Ticket 7fde638e94287d2c.
- 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

* 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,

* 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.

two passes.

* Fixed performance problems and potential stack overflows when
creating views from multi-row VALUES clauses with hundreds of
thousands of rows.

* 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.
