**Breaking changes**
~~~~~~~~~~~~~~~~~~~~

- Target PostgreSQL 14

- The wrapper classes used in previous versions, implemented in ``pglast.node``, are gone: now
everything works on top of the ``AST`` classes (`issue 80`__)

__ https://github.com/lelit/pglast/issues/80

- The ``Ancestor`` class is not iterable anymore: it was an internal implementation facility,
now moved to a ``_iter_members()`` method


Version 3

~~~~~~~~~~~~~~~~~

- Fix ``BooleanTest`` printer, enclosing expression within parens in more cases (`issue
129`__)

__ https://github.com/lelit/pglast/issues/129

- Fix ``Constraint`` printer, avoiding repetition of "DEFERRABLE INITIALLY DEFERRED" on some
kind of constraints (`issue 130`__)
