From 565b5e43b9b8abea565fb83b1f945eb83b2ca8a8 Mon Sep 17 00:00:00 2001 From: Alejandro Pedraza Date: Thu, 3 Sep 2020 14:28:47 -0500 Subject: [PATCH] Edge-20.9.1 release notes (#4942) ## edge-20.9.1 This edge release contains an important proxy update that allows linkerd to continue to operate normally in HA during node outages. We're also adding full Kubernetes 1.19 support! * Improved the proxy's error handling for DNS errors encountered when discovering control plane addresses, which can be common during installation, before all components have been started * The destination and identity services had to be made headless in order to support that new controller discovery (which now can leverage SRV records) * Use SAN fields when generating the linkerd webhook configs; this completes the Kubernetes 1.19 support which enforces them * Fixed `linkerd check` for multicluster that was spuriously claiming the absence of some resources * Improved the injection test cleanup (thanks @zhouhao3!) * Added ability to run the integration test suite using a cluster in an ARM architecture (thanks @aliariff!) --- CHANGES.md | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/CHANGES.md b/CHANGES.md index 227cfde40..90df4d8c6 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -1,5 +1,24 @@ # Changes +## edge-20.9.1 + +This edge release contains an important proxy update that allows linkerd to +continue to operate normally in HA during node outages.
