Consecutive windowed operations

In the 1.4 docs I stumbled on this section: Consecutive windowed operations <https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/stream/operators/windows.html#consecutive-windowed-operations>

This is very nice, but now I’m curious if it has always applied and was just not well documented or this is new behavior in 1.4 (side note: I’m trying to decide if I need to upgrade from 1.3.2 to 1.4).

Thanks!
Ron

Hi Ron,

chaining windows as shown in the example was also possible before 1.4.0.
So you can keep using Flink 1.3.2 if this would be the only reason to
update to 1.4.0.

Best, Fabian
