| October 29, 2015 |
| |

| =========== |
| Feb 2, 2015 |
| |
| Features |
| -------- |
| * Libuv 1.x supported |
| |
| Other |
| -------- |
| * `cass_cluster_set_num_threads_io()` now returns an error code |
| * Fixed an issue where a node in a remote DC could reconnect even if it |
| was supposed to be ignored. |

| |
| 1.0.0-rc1 |
| =========== |
| Dec 22, 2014 |
| |
| Features |
| -------- |
| * Added global logging. Logging is no longer configured per session. |
| * DC-aware load balancing policy is now the default and uses the DC of the first |
| connected contact point. The DC-aware policy now has settings to control the |
| number of remote hosts used in each DC (after exhausting the hosts in the |
| local DC) and whether to ignore local consistency levels. |
| * Added socket options for TCP nodelay and keepalive: |
| `cass_cluster_set_tcp_nodelay()` and `cass_cluster_set_tcp_keepalive()`. |
| |
| Other |
| -------- |
| * `CassSession` objects must now be explicitly allocated/freed using |
| `cass_session_new()` and `cass_session_free()`. `cass_cluster_connect()` has been |
| removed and replaced by `cass_session_connect()`. |
| * SIGPIPE is ignored on driver threads |
| * Connection timeout now covers the entire connection handshake instead of just |
| the socket connection. |
| * UUID API has been updated to use explict state via `CassUuidGen` instead of |
| using internal global state. See `cass_uuid_gen_new()` and corresponding functions. |
| |
| 1.0.0-beta5 |
| =========== |
| Nov 20, 2014 |
| |
| Features |
| -------- |
| * Added SSL support |
| * Added token-aware load balancing. It''s enabled by default. It can |
| be disable using `cass_cluster_set_token_aware_routing()`. |
| * Added functions to get schema metadata, `cass_session_get_schema()` can |
| be use to get a snapshot of the schema metadata and `cass_meta_*()` functions |
| can be used to retrieve detailed information about keyspaces, tables, and columns. |
| |
| Other |
| -------- |
| * Significantly improved request throughput by batching socket writes. |
| Batch sizes can be configured using the function |
| `cass_cluster_set_max_requests_per_flush()`. The default is 128 because |
| the maximum write size is bounded by the number of pipelined requests |
| per connection (for version 1 and 2 of the native protocol). |
| * Added backpressure mechanism that can be configured for by the |
| number of outstanding bytes and the number of requests on a connection. These can |
| be configured using `cass_cluster_set_write_bytes_high_water_mark()`, |
| `cass_cluster_set_write_bytes_low_water_mark()`, |
| `cass_cluster_set_pending_requests_high_water_mark()`, and |
| `cass_cluster_set_pending_requests_low_water_mark()`. |
| * Fixed a crash caused by a request timing out followed by a |
| call to the connection read callback then the write callback. |
| * Fixed an issue that prevented the driver from recovering from |
| a full cluster outage. |
| * Fixed an issue that allowed `uv_queue_work()` to be called from an |
| application thread. |
| * Added logic to prevent redundant node refreshes when establishing |
| a new connection from multiple IO workers. |
| * Fixed a crash caused by Cassandra 2.1.0 not returning metadata on |
| execute requests. |
| * Fixed a memory leak that could leak request handlers if the control |
| connection ran out of stream ids. |
| * Fixed a crash caused by calling an invalid timeout callback |
| when waiting for connection to become available in a pool. |
| * Build will use an external version of Boost if present. |
| |
| 1.0.0-beta4 |

| |
| Features |
| -------- |
| * Added node discovery and now handle topology/status change events |
| * Queries that modify schema wait for cluster schema agreement |
| * Added DC aware load balancing policy. The default policy is set to |
| round robin. |
| * Added new methods to configure the load balancing policy, |
| `cass_cluster_set_load_balance_round_robin()` and |
| `cass_cluster_set_load_balance_dc_aware()` |
| * It is now possible for a session future to return an error when |
| connecting to a cluster. This can occur when the driver is unable to connect |
| to any contact points or the provided authentication credentials are invalid. |
| |
| 1.0.0-beta3 |
| =========== |

| * Values can be retrieved by name from result sets |
| |
| Other |
| --------- |

| `cass_cluster_set_max_simultaneous_creation()`, and |
| `cass_cluster_set_max_simultaneous_requests_threshold()` |
| * Added `cass_result_column_name()` to get column name from a result set |
| |
| Bug Fixes |
| --------- |
| * Fixed `StreamManager` so it no longer causes stack corruption |
| * Fixed issue where connections would log "'Timed out during startup' error on startup for ..." |
| when a Session was closed while a connection was during its startup process |
| * Fixed Row and collections iterator so they return the first and last item properly |
