Today I wanted to set up a development environment for GraphX and when I visited Maven central repository (https://mvnrepository.com/artifact/org.apache.spark/spark-graphx) I saw that it was already available in 2.4.0 version. Does it mean that the new version of Apache Spark was released ? It seems quite surprising for me because I didn't find any release information and the 2.4 artifact was deployed 29/10/2018. Maybe somebody here has some explanation for that ?

Best regards,
