• Moved io.grpc.Context and io.grpc.Deadline from grpc-core to its own artifact, grpc-context. This is to allow wider usage of the API and avoid circular dependencies. grpc-core depends on the new artifact. (#2226)
• Avoid creating unnecessary threads in InProcess transport, which improves performance for short-lived channels and prevents non-determinism when using direct executor in tests. (#2108)
• Fix bug where Errors could end up being wrapped in RuntimeException (#2131)
• Fix a deadlock in TransportSet (#2258)
