Right. It was announced as being retired back in 2016 [1] which ended in 2018 [2]: > > *DeprecationAstyanax has been retired and is no longer under active > development but may receive dependency updates to ease migration away from > Astyanax.In place of Astyanax consider using DataStax Java Driver for > Apache Cassandra which is under active development and encapsulates a lot > of lessons learned from Astyanax.

C* 2.1 is on maintenance mode and will no longer be supported when C* 4.0 is released [3]. Cheers!
