Many new contributors joining us. For example, Giorgio Zoppi is working for TsFIle/IoTDB C++, Robinet integrated IoTDB with Apache Karaf, Xin Wang and Jincheng integrated IoTDB with Flink etc..
The website is refactored.

Now Google Search Engine can index it.
The website provides a detailed User Guide and some System Designs both in English and Chinese.
Meetup and other talk materials (slides and videos) are shared on the website.
More documents to let users joining us （like Code of Conduct, How to be a committer, how to release, how to vote new committers, etc..) are provided on the website or the wiki.
