 * Remove deprecated flag `--es.max-num-spans`, please use `--es.max-doc-count` ([#2482](https://github.com/jaegertracing/jaeger/pull/2482),[@BernardTolosajr](https://github.com/BernardTolosajr))
 
+* Remove deprecated flag `--jaeger.tags`, please use `--agent.tags` ([#2753](https://github.com/jaegertracing/jaeger/pull/2753), [@yurishkuro](https://github.com/yurishkuro))

 #### New Features
 
 * Add TLS Support for GRPC and HTTP endpoints of the Query server ([#2337](https://github.com/jaegertracing/jaeger/pull/2337), [@rjs211](https://github.com/rjs211))
 
     Enabling TLS in either or both of GRPC or HTTP endpoints forces the server to use dedicated host-port for the two endpoints.  The dedicated host-ports are set using the flags `--query.http-server.host-port` (defaults to `:16686`) and `--query.grpc-server.host-port` (defaults to `:16685`) for the HTTP and GRPC endpoints respectively. If either of both of the dedicated host-ports' flags are not explicitly set, the default values are used.
 
 
-    If TLS is disabled in both endpoints (default),  dedicated host-ports are used if either or both of `--query.http-server.host-port` or `--query.grpc-server.host-port`  is explicitly set. If only one of the dedicated host-port flags is set, the other flag uses its corresponding default value. If neither of the dedicated host-port flags are explicitly set, the common host-port infered from `--query.host-port` (defaults to `:16686`) is used for both the GRPC and HTTP endpoints.
