In the next release

0.1.1

linkerd-tcp 0.1.1 focuses on improving TLS support, and on updating linkerd-tcp's dependencies.

  • Trace negotiated SNI & ALPN at the end of the server handshake.
  • Improve handling and reporting of TLS configuration errors.
  • Update to latest versions of dependencies.
  • Switch the official Rust base docker image.
  • Remove use of deprecated downstream API members.
  • Remove dependency on nightly Rust to build linkerd-tcp.

0.1.0

linkerd-tcp 0.1.0 constitutes a major rewrite.

Previously, linkerd-tcp did not properly utilize tokio's task model, which lead to a number of performance and correctness problems. Furthermore, linkerd-tcp's configuration interface was substantially different from linkerd's, which caused some confusion.

  • Significant performance and correctness improvements.
  • Add support for connection and stream timeouts.
  • Add several additional metrics.
  • Breaking change: Change configuration file syntax to be structured like a Linkerd router:
    • Rename proxies key to routers
    • Change servers to take separate ip and port keys, rather than addr.
    • Change namerd section in server configuration to Linkerd-style interpreter section on a router configuration. The path key is now specified per-server as dstPath.

0.0.3

  • New admin endpoint! POST to /shutdown to tell the process to exit.
  • Fix connection leak when one peer disconnected.
  • Fix stat reporting issue for the rx bytes metric.
  • Improve error message when config file cannot be read.
  • Update examples to bind to all available sockets by default.
  • Add guidelines for contributing to the linkerd-tcp repo.
  • Add script for building a slimmer docker image.
  • Breaking change: Convert namerd config to use url field instead of addr.
  • Breaking change: Convert server config attributes from camel to snake case.

0.0.2

  • Expose a configurable admin server with Prometheus metrics.
