==========

Added `SQLITE_CONFIG_URI
<https://sqlite.org/c3ref/c_config_getmalloc.htmlsqliteconfiguri>`__
and support for it in :meth:`config`, and the open flag
`SQLITE_OPEN_URI
<https://sqlite.org/c3ref/c_open_autoproxy.html>`__. This makes it
easy to use `URI filenames <https://sqlite.org/uri.html>`__.

The :ref:`shell` now uses `URI filenames
<https://sqlite.org/uri.html>`__ by default.

New `extended error constants
<https://sqlite.org/c3ref/c_busy_recovery.html>`__:
SQLITE_CORRUPT_VTAB, SQLITE_IOERR_SEEK, SQLITE_IOERR_SHMMAP,
SQLITE_READONLY_CANTLOCK and SQLITE_READONLY_RECOVERY.

64 bit platforms
(`LP64 - most non-Windows
<http://en.wikipedia.org/wiki/64-bitSpecific_C-language_data_models>`__)
and Python 2: The Python int type is returned for 64 bit integers
instead of Python long type.

==========

When invoking the shell by calling :func:`apsw.main` it will not
become interactive if you supply SQL commands as command line
arguments. This is to have the same behaviour as the SQLite shell
(:issue:`115`).

The shell has a *.find* command making it easy to search for values
across all columns of some or all tables.

The shell has a *.autoimport* command making it easy to import a data
file automatically deducing separators, column names and data types.

Detect attempted use of a cursor as input data for itself.

==========

Fixed :issue:`117` where the
shell could report an I/O error on changing output target for some
operating systems. Thanks to Edzard Pasma for finding and diagnosing
this.

Added support for VFS version 3 which allows redirecting :meth:`system
calls <VFS.xSetSystemCall>` used by some VFS implementations (eg for
testing or sandboxing).

:exc:`NotFoundError` exception added.

Added :meth:`Connection.config`.

Updated :meth:`Connection.wal_checkpoint` to use `sqlite3_wal_checkpoint_v2
<https://sqlite.org/c3ref/wal_checkpoint_v2.html>`__ which provides
more fine grained control over checkpointing and returns useful
information.

========

Backwards incompatible change in SQLite 3.7.5 for handling of
:meth:`~VFSFile.xFileControl`. If you implement this method in a VFS
then you must return True or False to indicate if the operation was
understood. :meth:`Connection.filecontrol` now returns that value.
(Previously you could not tell the difference between an op being
understood and an error resulting, or the op not being understood at
all.)

Windows Python 3.2 binaries now available.

========

Binary downloads for Windows 64 bit Python versions 2.6 and above
including Python 3 are now available.

:meth:`apsw.softheaplimit` now uses `sqlite3_soft_heap_limit64
<https://sqlite.org/c3ref/soft_heap_limit64.html>`__ so you can
provide values larger than 2GB. It is now also able to return the
previous value instead of None.

Improve getting shell timer information for 64 bit Windows.

:meth:`blob.reopen` is implemented.

FTS4 is enabled and in the binary builds. Note that it is an
augmentation of FTS3 rather than totally separate code and described
in the `SQLite documentation
<https://sqlite.org/fts3.htmlfts4>`__.

========

You can read blobs into pre-existing buffers using
:meth:`blob.readinto`. (This is more efficient than allocating new
buffers as :meth:`blob.read` does and then copying.) (:issue:`109`).

Fixed bug with unicode output in CSV mode in the shell.

`sqlite_create_function_v2
<https://sqlite.org/c3ref/create_function.html>`__ now means that some
housekeeping APSW did can be pushed back onto SQLite and the
consequent deletion of some code
