 # Changes
 
+## [0.65.0](https://www.github.com/googleapis/google-cloud-go/compare/v0.64.0...v0.65.0) (2020-08-27)
+
+
+### Announcements
+
+The following changes will be included in an upcoming release and are not 
+included in this one.
+
+#### Default Deadlines
+
+By default, non-streaming methods, like Create or Get methods, will have a
+default deadline applied to the context provided at call time, unless a context
+deadline is already set. Streaming methods have no default deadline and will run
+indefinitely, unless the context provided at call time contains a deadline.
+
+To opt-out of this behavior, set the environment variable
+`GOOGLE_API_GO_EXPERIMENTAL_DISABLE_DEFAULT_DEADLINE` to `true` prior to
+initializing a client. This opt-out mechanism will be removed in a later
+release, with a notice similar to this one ahead of its removal.
+
