Apsw

=========

Added SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION constant.

Added a pip command line in the download page.

<https://github.com/pypa/cibuildwheel/releases/tag/v2.20.0>`__, as
well as `older Python ARM64
<https://github.com/rogerbinns/apsw/pull/530>`__ are available.

=========

Call `PyUnicode_READY <https://www.python.org/dev/peps/pep-0393/#new-api>`__ for
Python 3.3 onwards. Fixes :issue:`208`, :issue:`132`, :issue:`168`.

SQLite 3.12 completely changed the semantics of :meth:`VFS.xGetLastError` in an
incompatible way. This required a rewrite of the relevant C, Python and test
code. If you implement or use this method then you have to rewrite your code
too. Also note that running the test suite from an earlier version of APSW
against this or future SQLite versions will result in consuming all memory, swap
or address space (an underlying integer changed meaning).

Added SQLITE_CONFIG_STMTJRNL_SPILL and SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER
constants.

Added support for SQLITE_CONFIG_STMTJRNL_SPILL in :meth:`apsw.config`.

=========

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.
