=========

Windows binary distribution includes Python 3.1.

Trivial tweaks to keep MSVC happy.

=========

Fixed :issue:`50` where :meth:`blob.read` was returning :const:`None`
on end of file instead of the documented (and correct) empty
string/bytes.

Corrected spelling of option in :ref:`apswtrace <apswtrace>` and only
output CURSORFROM if SQL tracing is on.

===========

Updated test code because SQLite 3.6.15 returns a different error code
on trying to register a function with too many arguments (see
:cvstrac:`3875`).

===========

Changed some internal symbol names so they won't clash with similar
new ones used by SQLite in the amalgamation.

Added :attr:`apsw.using_amalgamation` so you can tell if APSW was
compiled using the `SQLite amalgamation
<https://sqlite.org/cvstrac/wiki?p=TheAmalgamation>`__. Using the
amalgamation means that SQLite shared libraries are not used and will
not affect your code.

Added a checksums file so that when :file:`setup.py` downloads SQLite,
we know it hasn't been tampered with. (The :ref:`--fetch-sqlite
<setup_py_flags>` argument can be used to automatically download
SQLite.)

=========

Added SQLITE_LOCKED_SHAREDCACHE `extended error code <https://sqlite.org/c3ref/c_ioerr_access.html>`_.

Updated tests as the VFS delete error handling code in SQLite now
returns the same high level error code between Windows and
non-Windows.

The CHM format help file produced by the Windows HTML Help Compiler is
viewable again under Windows HTML Help Viewer.

=========

You can now use the `hot backup functionality
<https://sqlite.org/backup.html>`_ introduced in SQLite 3.6.11.

Updated a VFS test to reflect changes in SQLite underlying error
handling. (Previously SQLite almost always returned :exc:`FullError`
on any write that had an error but now returns :exc:`SQLError`.)

Changed close methods so that Connections can be released earlier.

In prior releases a :meth:`closed cursor <Cursor.close>` could still be used
(reincarnated). That is no longer the case and you will get
:exc:`CursorClosedError`.
