NEW FEATURES

- No new features, but tons of bugfixes. These mean that things now work
that
  didn't before:
- Transactional DDL now works
- You can use SAVEPOINTs now


BUILD PROCESS

- Python 2.7.x is now required. If trying to use it with Python 3, print a
  useful error message.  Integrated all fixes from the sqlite3 module in
Python
  2.7.10.


MAJOR IMPROVEMENTS

- Completety got rid of statement parsing. We now use SQLite functions to
  determine if a statement modifies the database or not. If a statement
  modifies the database, then we implicitly start a transaction. For
backwards
  compatibility reasons, we do NOT implicitly start a transaction if we
  encounter a DDL statement.

  You can, however, now have transactional DDL if you want to:

    cur = con.cursor()
    cur.execute("begin")
    cur.execute("create table foo(bar)")
    con.rollback()

  This also means that people can now finally use SAVEPOINTS.

- Use sqlite3_get_autocommit() to determine if we are within a transaction
  instead of trying to be smart.

- Switch to v2 statement API. This simplified the code and will increase
  stability.

MINOR IMPROVEMENTS

- You can use unicode strings as index for Row objects.


BUGFIXES

- Fixed a regression: statements should not be reset after a commit.


GENERAL CLEANUP AND DEPRECATIONS

- Since december 2005, row_factory is a feature of the Connection class
instead
  of the Cursor class. It was kept in the Cursor class for backwards
  compatibility. Now it was time to finally remove it from the Cursor class.
- DEPRECATE converters and adapters.
- DEPRECATE text_factory.
- Remove compatibility workarounds for old Python versions.
- Remove workarounds for old SQLite versions.
- Remove apsw related code.
