+## v1.0.0 (2019-09-24)
+
+### New Features
+
+#### Sync Waves
+
+Sync waves feature allows executing a sync operation in a number of steps or waves. Within each synchronization phase (pre-sync, sync, post-sync) you can have one or more waves,
+than allows you to ensure certain resources are healthy before subsequent resources are synced.
+
+#### Optimized Interaction With Git
+
+Argo CD needs to execute `git fetch` operation to access application manifests and `git ls-remote` to resolve ambiguous git revision. The `git ls-remote` is executed very frequently
+and although the operation is very lightweight it adds unnecessary load on Git server and might cause performance issues. In v1.1 release, the application reconciliation process was
+optimized which significantly reduced the number of Git requests. With v1.1 release, Argo CD should send 3x ~ 5x fewer Git requests.
+
+#### User Defined Application Metadata
+
+User-defined Application metadata enables the user to define a list of useful URLs for their specific application and expose those links on the UI
+(e.g. reference tp a CI pipeline or an application-specific management tool). These links should provide helpful shortcuts that make easier to integrate Argo CD into existing
+systems by making it easier to find other components inside and outside Argo CD.
+
+### Deprecation Notice
+
+* Kustomize v1.0 is deprecated and support will be removed in the Argo CD v1.2 release.
