2.0.0.1
-------
- Improve exception handling while attempting to close connections and sockets.

2.0.0
-----
- Support multiple control connections with an upper limit and policy-controlled
  priority.
- Cabal file improvements: bounds, version, etc.
- Switch from unmaintained cryptonite to crypton
- Add sufficient API tools for token-routing aware policy:
  - Accessors to lookup the replication for a keyspace, and to get the replicas
    for a given prepared query and its query values.
- Pass prepared query and values to policy when selecting host
- Track replication information for keyspaces and nodes
- Better handling of prepared queries: Prevent re-prepare if the user has
  eagerly prepared a query.
- Better code sharing between default policies.
- Host events to pass Hosts, not addresses. This allows policies to better
  handle ups and downs, as well as re-numbering. It makes it easier to write a
  policy that prefers a given DC.
- Track peers more carefully, and track them via UUID, not address.
- Allow connection upgrading via min-max protocol version. Instead of setting a
  fixed protocol version, allow setting a min and max, and upgrade when
  possible.

Breaking Changes:
- Policy has a new `priority` function
- Policy Events now have `Host`s instead of addresses, except for the new
  `AddrDown` for the case of a `HostDown` CQL event where the `Host` in question
  can't be found.
- Policy `select` function accepts an additional argument with token-based
  routing information if it is available.
- Settings has `_minProtoVer` and `_maxProtoVer` instead of `_protoVersion`
- Settings has an additional field `_maxControlConnections`

Porting Guide:
  If using one of the included policies, the only necessary change should be to
set a minimum and maximum protocol versions instead of a single version.
  If not using an included policy, an existing policy can be ported by ignoring
the additional argument to select, and by adjusting the event handler to handle
`Host`s rather than addresses. Hosts have an address field, so porting should be
straightforward. However, the changed policy API makes it possible to have a
token aware routing policy. It's worth taking a look at that while porting. The
improved `HostEvent` API should make it easier to handle host renumbering more
gracefully as well.

1.1.1
-----
- Compatibility with `network >= 3`.

1.1.0
-----
- Improve configuration of retry settings and refactor exceptions
  (https://gitlab.com/twittner/cql-io/issues/13).
- Document and export the 'getResult' function alongside the low-level
  query API.
- Replace monad-control with unliftio.
- Remove dependency on tinylog, introducing a minimal logging interface that can
  be hooked up to any logging library. Tinylog integration has moved to
  the new cql-io-tinylog library.

1.0.1.1
-------

1.0.1
------

  problems with the automatic (re-)preparation of prepared queries upon
  'Unprepared' server responses.

------
- Add support for CQL V4 binary protocol.
- Remove support for CQL V2 binary protocol.
