Aljoscha Krettek updated FLINK-19326:
-------------------------------------
    Release Note: Before Flink 1.12 the CEP operations were changing their 
behavior based on the globally set Stream TimeCharacteristic. In Flink 1.12 we 
introduced explicit `inProcessingTime()` and `inEventTime()` methods on 
`PatternStream` and the CEP operations no longer change their behaviour based 
on the global characteristic.  (was: Before Flink 1.12 the CEP operations where 
changing their behavior based on the globally set Stream TimeCharacteristic. In 
Flink 1.12 we introduced explicit `inProcessingTime()` and `inEventTime()` 
methods on `PatternStream` and the CEP operations no longer change their 
behaviour based on the global characteristic.)

> With the deprecation of 
> {{StreamExecutionEnvironment.setStreamTimeCharacteristic()}} in FLINK-19319 
> we need a way of explicitly configuring the time behaviour of CEP operations. 
> Currently, all CEP operations use the characteristic to configure themselves.
