## Announcement gRPC Java releases 1.51.0, 1.51.1, and 1.52.0 have an important bug that can cause them to stop receiving updates from Traffic Director. We encourage users of gRPC Java to avoid these releases and use the older v1.50.x until patch releases with fixes are available. See the [public gRPC announcement](https://groups.google.com/g/grpc-io/c/roNyXX5pEAU?pli=1) for more information.
