- update to 3.42.0.0:
* Shell: Errors when SQLite are preparing a statement now show
the relevant extract of the query, and where the error was
detected.
* Shell: Output modes table (ASCII line drawing, lots of
sanitization), box (Unicode line drawing) and
qbox (box with quoted values) available.
* Shell: if started interactively then box is the default mode
(list remains the default in non-interactive)
* Added :meth:`Connection.pragma` to execute pragmas
and get results.
* Added :attr:`Cursor.get` returning query results with the
least amount of structure.
* Fixed execution tracers should return comment text for
comment only queries, and add :attr:`Cursor.has_vdbe`.
* Ensure that all applicable options are implemented for
:func:`apsw.config`, :meth:`Connection.config` and similar.
* Added :func:`apsw.sleep`
* Strings for :meth:`apsw.VFS.xNextSystemCall` are interned
* Detect unbound recursion not handled by CPython, and handle
better.
