* 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 the -> and ->> JSON operators so that when the right-hand side operand is a string that looks like an integer it is still treated as a string, because that is what PostgreSQL does.

*\" values of an UPDATE trigger to be incorrect if that trigger fires in response to an UPSERT.
* Reduce the scope of the NOT NULL strength reduction optimization that was added as item 8e in version 3.35.0. The optimization was being attempted in some contexts where it did not work, resulting in incorrect query results.- Add SQLITE_STRICT_SUBTYPE=1 as recommended by upstream.
* Tue Mar 12 2024 Reinhard Max - Update to release 3.45.2:
* Added the SQLITE_RESULT_SUBTYPE property for application- defined SQL functions.

* Query planner improvements
* Increase the default value for SQLITE_MAX_PAGE_COUNT from 1073741824 to 4294967294.
* Enhancements to the CLI

* Fix a long-standing bug in which a read of a few bytes past the end of a memory-mapped segment might occur when accessing a craftily corrupted database using memory-mapped database.
* 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.

* Thu Oct 19 2023 Reinhard Max - sqlite3-rtree-i686.patch: temporary build fix for 32-bit x86.
* Tue Oct 10 2023 Reinhard Max - Update to: 3.43.2:
* Fix a couple of obscure UAF errors and an obscure memory leak.

* Fix a regression in the way that the sum(), avg(), and total() aggregate functions handle infinities.
* Fix a bug in the json_array_length() function that occurs when the argument comes directly from json_remove().

* Sat Aug 26 2023 Andrea Manzini - Update to 3.43.0:
* Add support for Contentless-Delete FTS5 Indexes. This is a variety of FTS5 full-text search index that omits storing the content that is being indexed while also allowing records to be deleted.
* Enhancements to the date and time functions: + Added new time shift modifiers of the form ±YYYY-MM-DD HH:MM:SS.SSS. + Added the timediff() SQL function.
* Added the octet_length(X) SQL function.
* Added the sqlite3_stmt_explain() API.

Rename it to OUTER JOIN strength reduction. + Enhance the theorem prover in the OUTER JOIN strength reduction optimization so that it returns fewer false-negatives.
* Enhancements to the decimal extension: + New function decimal_pow2(N) returns the N-th power of 2 for integer N between -20000 and +20000. + New function decimal_exp(X) works like decimal(X) except that it returns the result in exponential notation - with a \"e+NN\" at the end. + If X is a floating-point value, then the decimal(X) function now does a full expansion of that value into its exact decimal equivalent.

* Query planner improvements.
* Add the --unsafe-testing command-line option.
* Allow commands \".log on\" and \".log off\", even in --safe mode.
* \"--\" as a command-line argument means all subsequent arguments that start with \"-\" are interpreted as normal non-option argument.

* Allow the session extension to be configured to capture changes from tables that lack an explicit ROWID.
* Added the subsecond modifier to the date and time functions.
* Negative values passed into sqlite3_sleep() are henceforth interpreted as 0.

* Add the --safe command-line option that disables dot-commands and SQL statements that might cause side-effects that extend beyond the single database file named on the command-line.
* CLI: Performance improvements when reading SQL statements that span many lines.
* 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. This is done as a way to demonstrate how to write table-valued functions with required parameters. The legacy behavior is available using the -DZERO_ARGUMENT_GENERATE_SERIES compile-time option.

* 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.

* Enhance the OP_OpenDup opcode of the bytecode engine so that it works even if the cursor being duplicated itself came from OP_OpenDup

* Fix some incorrect assert() statements
* 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

* Fri Mar 19 2021 Martin Liška - Fix typo in macro definition.
* Wed Mar 17 2021 Andreas Stieger - SQLite 3.35.2:

* Limit the new UNION ALL optimization described by item 8c in the 3.35.0 release so that it does not try to make too many new subqueries.- include changes from 3.35.1:
* Fix a bug in the new DROP COLUMN feature when used on columns that are indexed and that are quoted in the index definition.
* Improve the built-in documentation for the .dump command in the CLI.
* Mon Mar 15 2021 Dirk Müller - update to 3.35.0:

* The final ON CONFLICT clause may omit the conflict target and yet still use DO UPDATE.
* Add support for the RETURNING clause on DELETE, INSERT, and UPDATE statements.
* Use less memory when running VACUUM on databases containing very large TEXT or BLOB values. It is no longer necessary to hold the entire TEXT or BLOB in memory all at once.

* The SQLITE_DBCONFIG_ENABLE_TRIGGER and SQLITE_DBCONFIG_ENABLE_VIEW settings are modified so that they only control triggers and views in the main database schema or in attached database schemas and not in the TEMP schema. TEMP triggers and views are always allowed.
* Query planner/optimizer improvements
* Enhance the \".stats\" command to accept new arguments \"stmt\" and \"vmstep\", causing prepare statement statistics and only the virtual-machine step count to be shown, respectively.

* Enhance the \".once\" and \".output\" commands so that if the destination argument begins with \"|\" (indicating that output is redirected into a pipe) then the argument does not need to be quoted.

* Fix documentation typos
* Fix minor problems in extensions
* Wed Dec 02 2020 Reinhard Max - SQLite 3.34.0:
* Added the sqlite3_txn_state() interface for reporting on the current transaction state of the database connection.
* Enhance recursive common table expressions to support two or more recursive terms as is done by SQL Server, since this helps make queries against graphs easier to write and faster to execute.

* 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.

* The BEGIN IMMEDIATE and BEGIN EXCLUSIVE commands now work even if one or more attached database files are read-only.
* Enhanced FTS5 to support trigram indexes.
* Improved performance of WAL mode locking primitives in cases where there are hundreds of connections all accessing the same database file at once.
