* Improved robustness while parsing the tokenize= arguments in FTS5.
* Enhancements to covering index prediction in the query planner.
* Do not let the number of terms on a VALUES clause be limited by SQLITE_LIMIT_COMPOUND_SELECT, even if the VALUES clause contains elements that appear to be variables due to double-quoted string literals.
* Fix the window function version of group_concat() so that it returns an empty string if it has one or more empty string inputs.
* In FTS5 secure-delete mode, fix false-positive integrity-check reports about corrupt indexes.
* Syntax errors in ALTER TABLE should always return SQLITE_ERROR. In some cases, they were formerly returning SQLITE_INTERNAL.
* Other minor fixes.

* https://sqlite.org/releaselog/3_46_0.html
* Enhance PRAGMA optimize in multiple ways.
* Enhancements to the date and time functions.
* Add support for underscore (\"_\") characters between digits in numeric literals.
* Add the json_pretty() SQL function.
* Query planner improvements.
* Allocate additional memory from the heap for the SQL parser stack if that stack overflows, rather than reporting a \"parser stack overflow\" error.
* Allow ASCII control characters within JSON5 string literals.

* Fix a long-standing bug in which a NULL pointer dereference might occur in the bytecode engine due to incorrect bytecode being generated for a class of SQL statements that are deliberately designed to stress the query planner but which are otherwise pointless.
* Fix an error in UPSERT, introduced in version 3.35.0.
* Reduce the scope of the NOT NULL strength reduction optimization that was added in version 3.35.0.- Add sqlite3-float-i586.patch to fix build on i586.- sqlite3-rtree-i686.patch is not needed anymore.- Abort build when %version and %tarversion don\'t match.

* Query planner improvements.
* Add the --unsafe-testing command-line option.
* Allow commands \".log on\" and \".log off\", even in --safe mode.

* Added the sqlite3_autovacuum_pages() interface.
* The sqlite3_deserialize() does not and has never worked for the TEMP database. That limitation is now noted in the documentation.
* The query planner now omits ORDER BY clauses on subqueries and views if removing those clauses does not change the semantics of the query.
* The generate_series table-valued function extension is modified so that the first parameter (\"START\") is now required.

* The sqlite3_deserialize() and sqlite3_serialize() interfaces are now enabled by default. The -DSQLITE_ENABLE_DESERIALIZE compile-time option is no longer required. Instead, there is a new -DSQLITE_OMIT_DESERIALIZE compile-time option to omit those interfaces.
* The \"memdb\" VFS now allows the same in-memory database to be shared among multiple database connections in the same process as long as the database name begins with \"/\".
* Back out the EXISTS-to-IN optimization (item 8b in the SQLite 3.35.0 change log) as it was found to slow down queries more often than speed them up.

* Fix to the SELECT statement syntax diagram so that the FROM clause syntax is shown correctly
* Fix the EBCDIC character classifier so that it understands newlines as whitespace

* The --init option reports an error if the file named as its argument cannot be opened. The --init option also now honors the - -bail option.
* Improved estimates for the cost of running a DISTINCT operator.
* When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks.

* 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.

* Pass information about !=, IS, IS NOT, NOT NULL, and IS NULL constraints into the xBestIndex method of virtual tables.
* Enhanced the CSV virtual table so that it accepts the last row of input if the final new-line character is missing.

* 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.

* 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.

* 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.

* Mon Nov 21 2016 astiegerAATTsuse.com- SQLite 3.15.1:
* Fix the VACUUM command so that it spills excess content to disk rather than holding everything in memory, and possible causing an out-of-memory error for larger database files
* Fix a case where OR-connected terms in the ON clause of a LEFT JOIN might cause incorrect results
