 ## Current
 
-### Build new components
+**MWC is currently in maintenance mode,
+[see this announcement](https://github.com/material-components/material-web/discussions/5642)
+for more details.**
 
-*Planned for 2024*
+There is no current work planned for new features or components. Bug fixes or
+other contributions may be added on a case-by-case basis.
 
-One of our core goals is to provide Material Design components for the web.
-These are the components we are currently working on.
+## Future
+
+**Note: No future work is planned while MWC is in
+[maintenance mode](https://github.com/material-components/material-web/discussions/5642).**
+These roadmap items represent what used to be planned.

 ### Expand Material Design tokens
 
-*Planned for Q1 2024*
-
 We are adding shape and motion system tokens to support building expressive
 Material experiences.
 
 We also want to make it easier to use Material Design tokens, such as applying
 Material typescale, shape, and color to your own components.
 
-### Create TSX components
+### Density and spacing tokens
 
-*Planned for Q1 2024*
+Density allows components to take up less vertical space for larger displays.
+While we have some spacing tokens already, we need a comprehensive spacing
+system to fully support density across components.
+
+### Create TSX components
 
 [TSX](https://www.typescriptlang.org/docs/handbook/jsx.html) is a popular
 language extension for frameworks like [React](https://reactjs.org/). We want to
 make it easier and more seamless to use Material Web Components in TSX.
 
-### Follow accessibility best practices
-
-*Planned for Q2 2024*
-
-Everyone should be able to access and enjoy the web. We want our components to
-help others build accessible experiences.
-
-We are working on supporting all of the following screen readers:
-
-*   VoiceOver
-*   Talkback
-*   ChromeVox
-*   JAWS
-*   NVDA
-
 ### Explore Material Design layouts
 
-*Planned for Q4 2024*
-
 Components are only part of the story to build fully expressive Material Design
 applications. We want to explore ways to support building applications that
 follow
 [Material's layout patterns](https://m3.material.io/foundations/layout/understanding-layout/overview).
