+### APIs
+
+#### Remove deprecated methods in ExecutionConfig [FLINK-19084](https://issues.apache.org/jira/browse/FLINK-19084)
+
+Deprecated method `ExecutionConfig#isLatencyTrackingEnabled` was removed, you can use `ExecutionConfig#getLatencyTrackingInterval` instead. 
+
+Deprecated and methods without effect were removed: `ExecutionConfig#enable/disableSysoutLogging`, `ExecutionConfig#set/isFailTaskOnCheckpointError`.
+
+Removed `-q` flag from cli. The option had no effect. 
+
+#### Remove deprecated RuntimeContext#getAllAccumulators [FLINK-19032](https://issues.apache.org/jira/browse/FLINK-19032)
+
+The deprecated method `RuntimeContext#getAllAccumulators` was removed. Please use `RuntimeContext#getAccumulator` instead. 
+
+#### Deprecated CheckpointConfig#setPreferCheckpointForRecovery due to risk of data loss [FLINK-20441](https://issues.apache.org/jira/browse/FLINK-20441)
+
+The `CheckpointConfig#setPreferCheckpointForRecovery` method has been deprecated, because preferring older checkpoints over newer savepoints for recovery can lead to data loss.
+
+#### FLIP-134: Batch execution for the DataStream API
+
+- Allow explicitly configuring time behaviour on `KeyedStream.intervalJoin()` [FLINK-19032](https://issues.apache.org/jira/browse/FLINK-19032)
+
+  Before Flink 1.12 the `KeyedStream.intervalJoin()` operation was changing behavior based on the globally set Stream TimeCharacteristic. In Flink 1.12 we introduced explicit `inProcessingTime()` and `inEventTime()` methods on `IntervalJoin` and the join no longer changes behaviour based on the global characteristic. 
+
+- Deprecate `timeWindow()` operations in DataStream API [FLINK-19318](https://issues.apache.org/jira/browse/FLINK-19318)
+
+  In Flink 1.12 we deprecated the `timeWindow()` operations in the DataStream API. Please use `window(WindowAssigner)` with either a `TumblingEventTimeWindows`, `SlidingEventTimeWindows`, `TumblingProcessingTimeWindows`, or `SlidingProcessingTimeWindows`. For more information, see the deprecation description of `TimeCharacteristic`/`setStreamTimeCharacteristic`. 

Review comment:
       I assume this has been added because the deprecation of the timeWindow() is part of the time characteristic change, which is described in the deprecation description.
