Announcing Linkerd2 edge-20.12.4


Alex Leong
 

Dear Linkerd-ers,

We're very pleased to announce that Linkerd2 edge-20-12.4 has been released!

This edge release continues to polish the Linkerd extension model and improves
the robustness of the opaque transport.

To install this edge release, run:
curl https://run.linkerd.io/install-edge | sh

Full release notes:
  • Improved the consistency of behavior of the check commands between
    Linkerd extensions
  • Fixed an issue where Linkerd extension commands could be run before the
    extension was fully installed
  • Renamed some extension Helm charts for consistency:
    • jaeger -> linkerd-jaeger
    • linkerd2-multicluster -> linkerd-multicluster
    • linkerd2-multicluster-link -> linkerd-multicluster-link
  • Fixed an issue that could cause the inbound proxy to fail meshed HTTP/1
    requests from older proxies (from the stable-2.8.x vintage)
  • Changed opaque-port transport to be advertised via ALPN so that new proxies
    will not initiate opaque-transport connections to proxies from prior edge
    releases
  • Added inbound proxy transport metrics with tls="passhtru" when forwarding
    non-mesh TLS connections
  • Thanks to @hs0210 for adding new unit tests!
As always, we're excited to hear your feedback! Please try out the new release and send questions/comments to us on this mailing list, and bugs via GitHub.

A quick correction: the version we released yesterday was edge-21.1.4.  Sorry for the confusion!
