[ANNOUNCE] Weekly Community Update 2020/07

[Konstantin Knauf-2]

Dear community,

happy to share this week's community digest with the release of Flink 1.10, a proposal for better changelog support in Flink SQL, a documentation style guide, the Flink Forward San Francisco schedule and a bit more.

Flink Development

==============

* [releases] Apache Flink 1.10 has been released! [1] Read all about it in Marta's release blog post [2]. With the release of Flink 1.10 (technically already Flink 1.9.2), the maintenance of the "official" Flink Docker images [3] has moved to the Apache Flink project. [4]

* [releases] Moreover, you can now also find apache-flink on PyPi [5]

  * https://pypi.org/project/apache-flink/1.9.2/#files

  * https://pypi.org/project/apache-flink/1.10.0/#files

* [releases] Chesnay published a third release candidate for flink-shaded 10.0. on Wednesday. Only +1s so far. [6]

* [sql] Jark has published FLIP-105, which proposes to support changelog streams in Flink SQL. In essence, this means being able to interpret changelogs (Debezium, compacted topics, ...) as a dynamic table in update mode. Afterwards, the resulting continuously updating table could be directly used in a (temporal table) joins and aggregations. [7]

* [sql] Dawid has started a discussion on moving around packages in the Table API in order to greatly simplify the required imports for users of the Table API. [8]

* [cep] Shuai Xu proposes to support notFollowedBy() as the last part of a pattern, if an additional "within" time interval is given. He is waiting for feedback on his design document. [9]

* [development process] The documentation style guide [10] has finally been merged. Thanks to Marta, Robert, Aljoscha and others for driving this.

* [connectors] Dawid proposes to drop the ElasticSearch 2.x and 5.x connector. There is a consensus to drop 2.x, but some uncertainty about the current usage of 5.x connector. Please get involved in that thread if you are using ElasticSearch 5.x sink right now. [11]
