    💥 Breaking Changes

    • ✂ Remove deprecated TLS flags (#2790, @albertteoh):

      • --cassandra.tls is replaced by --cassandra.tls.enabled
      • --cassandra-archive.tls is replaced by --cassandra-archive.tls.enabled
      • --collector.grpc.tls is replaced by --collector.grpc.tls.enabled
      • --collector.grpc.tls.client.ca is replaced by --collector.grpc.tls.client-ca
      • --es.tls is replaced by --es.tls.enabled
      • --es-archive.tls is replaced by --es-archive.tls.enabled
      • --kafka.consumer.tls is replaced by --kafka.consumer.tls.enabled
      • --kafka.producer.tls is replaced by --kafka.producer.tls.enabled
      • --reporter.grpc.tls is replaced by --reporter.grpc.tls.enabled

    • ✂ Remove deprecated flags of Query Server --query.port and --query.host-port, please use dedicated HTTP --query.http-server.host-port (defaults to :16686) and gRPC --query.grpc-server.host-port (defaults to :16685) host-ports flags instead (#2772, @rjs211)

      • By default, if no flags are set, the query server starts on the dedicated ports. To use common port for gRPC and HTTP endpoints, the host-port flags have to be explicitly set

      • --collector.zipkin.http-port is replaced by --collector.zipkin.host-port

    • ✂ Remove deprecated flags --health-check-http-port & --admin-http-port, please use --admin.http.host-port (#2752, @pradeepnnv)

    • ✂ Remove deprecated flag --es.max-num-spans, please use --es.max-doc-count (#2482, @BernardTolosajr)

    • ✂ Remove deprecated flag --jaeger.tags, please use --agent.tags (#2753, @yurishkuro)

    • ✂ Remove deprecated Cassandra flags (#2789, @albertteoh):

      • --cassandra.enable-dependencies-v2 - Jaeger will automatically detect the version of the dependencies table
      • --cassandra.tls.verify-host - please use --cassandra.tls.skip-host-verify instead

    • ✂ Remove incorrectly scoped downsample flags from the query service (#2782, @joe-elliott)

      • --downsampling.hashsalt removed from jaeger-query
      • --downsampling.ratio removed from jaeger-query

    🆕 New Features

      • If TLS in enabled on either or both of gRPC or HTTP endpoints, the gRPC host-port and the HTTP host-port have to be different
      • If TLS is disabled on both endpoints, common HTTP and gRPC host-port can be explicitly set using the following host-port flags respectively:
        • Query: --query.http-server.host-port and --query.grpc-server.host-port
        • Collector: --collector.http-server.host-port and --collector.grpc-server.host-port
