:ref:`Upgrade Notes <upgrade_v2_0>`

.. warning:: TinyDB changed the way data is stored. You may need to migrate
your databases to the new scheme. Check out the
:ref:`Upgrade Notes <upgrade_v2_0>` for details.

- The syntax ``query in db`` has been removed, use ``db.contains`` instead.
- The ``ConcurrencyMiddleware`` has been removed due to a insecure implementation
(see `issue 18 <https://github.com/msiemens/tinydb/issues/18>`_). Consider
:ref:`tinyrecord` instead.

- Better support for working with :ref:`Document IDs <document_ids>`.
- Added support for `nested comparisons <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#nested-queries>`_.
- Added ``all`` and ``any`` `comparisons on lists <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#nested-queries>`_.
- Added optional :<http://tinydb.readthedocs.io/en/v2.0.0/usage.html#smart-query-cache>`_.
- The query cache is now a :ref:`fixed size LRU cache <query_caching>`.

^^^^^^^^^^^^^^^^^^^

(see `issue 8 <https://github.com/msiemens/tinydb/issues/8>`_).

^^^^^^^^^^^^^^^^^^^

- Fixed `bug 7 <https://github.com/msiemens/tinydb/issues/7>`_: IDs not unique.
- Extended the API: ``db.count(where(...))`` and ``db.contains(where(...))``.
- The syntax ``query in db`` is now **deprecated** and replaced
by ``db.contains``.

^^^^^^^^^^^^^^^^^^^

(see `issue 6 <https://github.com/msiemens/tinydb/issues/6>`_).
