Tinydb

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

- Fix a bug when using unhashable documents (lists, dicts) with
``Query.any`` or ``Query.all`` queries
(see `a forum post by karibul <https://forum.m-siemens.de/d/4-error-with-any-and-all-queries>`_).

(see `a forum post by karibul <https://forum.m-siemens.de/d/4-error-with-any-and-all-queries>`_).

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

- Inserting a dictionary with data that is not JSON serializable doesn't
lead to corrupt files anymore (see `issue 89 <https://github.com/msiemens/tinydb/issues/89>`_).
- Fix a bug in the LRU cache that may lead to an invalid query cache
(see `issue 87 <https://github.com/msiemens/tinydb/issues/87>`_).

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

- ``db.update(...)`` and ``db.remove(...)`` now return affected document IDs
(see `issue 83 <https://github.com/msiemens/tinydb/issues/83>`_).
- Inserting an invalid document (i.e. not a ``dict``) now raises an error
instead of corrupting the database (see
`issue 74 <https://github.com/msiemens/tinydb/issues/74>`_).

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

- Overhauled Query model:

- ``where('...').contains('...')`` has been renamed to
``where('...').search('...')``.
- Support for ORM-like usage:
``User = Query(); db.search(User.name == 'John')``.
- ``where('foo')`` is an alias for ``Query().foo``.
- ``where('foo').has('bar')`` is replaced by either
``where('foo').bar`` or ``Query().foo.bar``.

- In case the key is not a valid Python identifier, array
notation can be used: ``where('a.b.c')`` is now
``Query()['a.b.c']``.

- Checking for the existence of a key has to be done explicitly:
``where('foo').exists()``.

- Migrations from v1 to v2 have been removed.
- ``SmartCacheTable`` has been moved to `msiemens/tinydb-smartcache`_.
- Serialization has been moved to `msiemens/tinydb-serialization`_.
- Empty storages are now expected to return ``None`` instead of raising ``ValueError``.

- Allow custom parameters for custom test functions
(see `issue 63 <https://github.com/msiemens/tinydb/issues/63>`_ and
