 # Changelog
 
+## 2.3.0-rc2 (2019-04-21)
+
+### Changes since 2.3.0-rc1
++ Support parameter substitution in the volumes attribute (#1238)
+- Fix regression where argoexec wait would not return when podname was too long
+- wait will conditionally become privileged if main/sidecar privileged (issue #1323)
+- `argo list` was not displaying non-zero priorities correctly
+- Pod creation with secret volumemount (#1318)
+- Export the methods of `KubernetesClientInterface` (#1294)
+
+
+## 2.3.0-rc1 (2019-04-10)
+
+### Notes about upgrading from v2.2
+
+* Secrets are passed to the wait sidecar using volumeMounts instead of performing K8s API calls
+ performed by the. This is much more secure since it limits the privileges of the workflow pod
+ to no longer require namespace level secret access. However, as a consequence, workflow pods which
+ reference a secret that does not exist, will now indefinitely stay in a Pending state, as opposed
+ to the previous behavior of failing during runtime.
+
+
+### Deprecation Notice
+The workflow-controller-configmap introduces a new config field, `executor`, which is a container 
+spec and provides controls over the executor sidecar container (i.e. `init`/`wait`). The fields
+`executorImage`, `executorResources`, and `executorImagePullPolicy` are deprecated and will be
+removed in a future release.
+
+### New Features:
++ Support for PNS (Process Namespace Sharing) executor (#1214)
++ Support for K8s API based Executor (#1010) (@dtaniwaki)
++ Adds limited support for Kubelet/K8s API artifact collection by mirroring volume mounts to wait sidecar
++ Support HDFS Artifact (#1159) (@dtaniwaki)
++ System level workflow parallelism limits & priorities (#1065)
++ Support larger workflows through node status compression (#1264)
++ Support nested steps workflow parallelism (#1046) (@WeiTang114)
++ Add feature to continue workflow on failed/error steps/tasks (#1205) (@schrodit)
++ Parameter and Argument names should support snake case (#1048) (@bbc88ks)
++ Add support for ppc64le and s390x (#1102) (@chenzhiwei)
++ Install mime-support in argoexec to set proper mime types for S3 artifacts
++ Allow owner reference to be set in submit util (#1120) (@nareshku)
++ add support for hostNetwork & dnsPolicy config (#1161) (@Dreamheart)
++ Add schedulerName to workflow and template spec (#1184) (@houz42)
++ Executor can access the k8s apiserver with a out-of-cluster config file (@houz42)
++ Proxy Priority and PriorityClassName to pods (#1179) (@dtaniwaki)
++ Add the `mergeStrategy` option to resource patching (#1269) (@ian-howell)
++ Add workflow labels and annotations global vars (#1280) (@discordianfish)
++ Support for optional input/output artifacts (#1277)
++ Add dns config support (#1301) (@xianlubird)
++ Added support for artifact path references (#1300) (@Ark-kun)
++ Add support for init containers (#1183) (@dtaniwaki)
++ Secrets should be passed to pods using volumes instead of API calls (#1302)
++ Azure AKS authentication issues #1079 (@gerardaus)
+
+### New Features:
+* Update dependencies to K8s v1.12 and client-go 9.0
+* Add namespace explicitly to pod metadata (#1059) (@dvavili)
