 - **Database:** Fixed a bug in ``Database::connect()`` which was causing to store non-shared connection instances in shared cache.
 - **Database:** Fixed a bug in ``Connection::getFieldData()`` for ``SQLSRV`` and ``OCI8`` where extra characters were returned in column default values (specific to those handlers), instead of following the convention used by other drivers.
 - **Database:** Fixed a bug in ``BaseBuilder::compileOrderBy()`` where the method could overwrite ``QBOrderBy`` with a string instead of keeping it as an array, causing type errors and preventing additional ``ORDER BY`` clauses from being appended.
+- **Database:** Fixed a bug in ``SQLite3`` where the password parameter was ignored unless it was an empty string.
 - **Forge:** Fixed a bug in ``Postgre`` and ``SQLSRV`` where changing a column's default value using ``Forge::modifyColumn()`` method produced incorrect SQL syntax.
 - **Model:** Fixed a bug in ``Model::replace()`` where ``created_at`` field (when available) wasn't set correctly.
 - **Model:** Fixed a bug in ``Model::insertBatch()`` and ``Model::updateBatch()`` where casts were not applied to inserted or updated values.
