=========

setup.py attempts to use setuptools if present, before falling back to
distutils. This allows setuptools only commands such as bdist_wheel to work. You
can force use of distutils by setting the environment variable
APSW_FORCE_DISTUTILS to any value. Note that setuptools may also affect the
output file names. (:issue:`207`)

==========

The shell dump command now outputs the page size and user version. They were
both output before as comments.

Updated SQLite download logic for 2016 folder.

Updated VFS test suite due to changes in SQLite default VFS implemented methods.

Added SQLITE_INDEX_CONSTRAINT_LIKE, SQLITE_INDEX_CONSTRAINT_REGEXP,
SQLITE_INDEX_CONSTRAINT_GLOB, SQLITE_IOERR_AUTH, SQLITE_FCNTL_JOURNAL_POINTER,
and SQLITE_FCNTL_VFS_POINTER constants.

Allow :class:`Connection` subclasses for backup api (:issue:`199`).

`FTS5 <https://www.sqlite.org/fts5.html>`__ and `JSON1
<https://www.sqlite.org/json1.html>`__ extensions are now built by default for
:code:`--enable-all-extensions`. It is recommended you wait a few more
releases for these extensions to mature.

Added a mapping for `virtual table scan flags
<https://sqlite.org/c3ref/c_index_scan_unique.html>`__

Use `SQLITE_ENABLE_API_ARMOR
<https://www.sqlite.org/compile.html#enable_api_armor>`__ for extra error
checking.

========

Added SQLITE_IOERR_VNODE constant.

Windows builds for Python 3.5 are now provided.

===========

Added SQLITE_FCNTL_RBU and SQLITE_FCNTL_ZIPVFS constants.

setup's fetch command can now get arbitrary fossil versions. For
example specify ``fossil-e596a6b6``.

Update tests due to a change in Python 3.5 (exception returned with
invalid strings for system calls changed from TypeError to
ValueError).

Adjusted some internal detection related to the :func:`fork checker
<fork_checker>`

===========

Added deterministic parameter to
:func:`Connection.create_scalar_function` (:issue:`187`)

Switched to new SQLite API returning 64 bit values for :func:`status`
(:issue:`191`)

========

Fixed column description caching which could be preserved between
multiple statements in the same execution (:issue:`186`)

Updated documentation building tool to use new database of information
from the SQLite site. This is simpler and more reliable. (Previously
used site scraping.)

Added SQLITE_AUTH_USER, SQLITE_FCNTL_LAST_ERRNO,
SQLITE_FCNTL_WAL_BLOCK, SQLITE_FCNTL_GET_LOCKPROXYFILE, and
SQLITE_FCNTL_SET_LOCKPROXYFILE constants.

Removed SQLITE_GET_LOCKPROXYFILE, SQLITE_SET_LOCKPROXYFILE,
SQLITE_LAST_ERRNO file control constants. These are deprecated - use
the versions with FCNTL in their name (eg
SQLITE_FCNTL_GET_LOCKPROXYFILE).

Added :ref:`mappings <sqliteconstants>` for conflict resolution modes,
virtual table configuration options and xShmLock VFS flags.
