+# SharePoint Framework v1.12.0 release notes
 
 This release introduces a new property & event in the Web Part API to detect the rendering width (and changes), improved support for Microsoft Teams solutions, and updates supported versions of Node.js.
 
 **Released:** March 15, 2021
 
-
 > [!CAUTION]
-> Version 1.12 release is currently considered as deprecated due the unexpected regressions. We recommend usage of [v1.11](release-1.11.0.md) until updated version is available.
-
-## Upgrading projects from v1.11 to v1.12
-
-1. In the project's **package.json** file, identify all SPFx v1.11 packages. For each SPFx package:
-    1. Uninstall the existing v1.11 package:
-
-        ```console
-        npm uninstall @microsoft/{spfx-package-name}@1.11
-        ```
-
-    1. Install the refreshed v1.12 {version-release} package:
-
-        ```console
-        npm install @microsoft/{spfx-package-name}@1.12 --save --save-exact
-        ```
-
-> [!TIP]
-> The [CLI for Microsoft 365](https://aka.ms/o365cli) provides an easy step-by-step guidance to [upgrade](https://pnp.github.io/cli-microsoft365/cmd/spfx/project/project-upgrade/) your solutions to latest SharePoint Framework version.

-## New features and capabilities
-
-- The **Sync to Teams** button in the Tenant App Catalog will use the Teams app manifest defined in the solution if present to create and publish a Teams app package to Microsoft Teams. If an app manifest file is not present, SharePoint will dynamically generate one.
-  - *See [Deployment options for SharePoint Framework solutions for Microsoft Teams](deployment-spfx-teams-solutions.md) for more details.*
-- A new API has been added to the SPFx web part class to determine the rendered width of a web part and optionally handle an event when it changes.
-  - *See [Determine the rendered web part size](web-parts/basics/determine-web-part-width.md) for more details.*
-- Preliminary support for Microsoft Teams meeting apps with the SharePoint Framework - full support is pending a fix for server side regression
-
-## Changes in this release
-
-- Add support for **Node.js v12**
-  - *See [Set up your SharePoint Framework development environment](set-up-your-development-environment.md) for details.*
-  - **Gulp v4** (installed globally) is required (*see [Regarding Gulp versions & Node.js v12+](#gulp-versions--nodejs-v12) for details*)
-- For all projects:
-  - Update the default version of TypeScript to **v3.7** (*via **@microsoft/rush-stack-compiler-3.7** v0.2.3*)
-  - Update the **Gulp** version used to **v4.0.2**
-- For projects that use React:
-  - Update the React NPM packages (**react** & **react-dom**) to **v16.9.0**.
-  - Update the Office UI Fabric React NPM package / Microsoft Fluent UI (**office-ui-fabric-react**) to **v7.156.0**.
-
-## Deprecations and removed items in this release
-
-- **Gulp v3** is not supported (*neither globally nor locally installed*) when using Node.js v12+.
-- **Local workbench is deprecated** - This is the last release that will include support for the local workbench.
-- This is the last release that will include a single generator that works for on-prem and SharePoint Online.  You'll still be able to create projects for on-prem, just by using the older generator.
-
-### Gulp versions & Node.js v12+
-
-Gulp v3 isn't supported with Node.js v12+ (*ref [gulpjs/gulp/#2324](https://github.com/gulpjs/gulp/issues/2324)*).
-
-This is not a change with SPFx. Its mentioned here to bring attention to it as this SPFx release adds support for Node.js v12.
+> Version 1.12 release is currently considered as deprecated and has been unpublished due the unexpected regressions.
+>
+> We recommend usage of [v1.11](release-1.11.0.md) until updated version is available.
