New Committer: Conglei Shi

[Jeff Feng <je...@airbnb.com.INVALID>]

The Project Management Committee (PMC) for Apache Superset has invited
Conglei Shi to become a committer and we are pleased to announce that he
has accepted.

Being a committer enables easier contribution to the project since there is
no need to go via the patch submission process. This should enable better
productivity.

Best,
Apache Superset PMC
