Subject Re: [VOTE] Release Apache Flink 1.3.1
Date Mon, 19 Jun 2017 12:02:09 GMT
I think this actually not true, since in 1.3.0 the field `enumConstants` in
`ScalaEnumSerializerConfigSnapshot` was always serialized as `null`. Thus,
due to this we wouldn't have to bump the format if we included FLINK-6948
in 1.3.1. If this weren't the case, we would have to bump it also for 1.3.1
(excluding FLINK-6948).

Cheers,
Till
