+## [Depreaction Stages RFC is out!](https://github.com/emberjs/rfcs/pull/649)
+
+A new RFC takes Ember's promise of "stability without stagnation" to the next level
+by introducing "Deprecation Stages". After multiple months of weekly discussions,
+the [Deprecation Process strike team](https://discord.com/channels/480462759797063690/690649313457602651) details a process to introduce deprecations
+that will both allow early adopters to move <span style="font-style: italic;">faster</span> and large apps to wait for the
+dust to settle. [Check out the RFC and weigh in!](https://github.com/emberjs/rfcs/pull/649)
